GridViews/DetailsView (only Appear After Control Selection)
May 5, 2008
Hi all,
I want to be able to implement what the following site shows in regards to dynamically displaying Data views of various types:
http://quickstarts.asp.net/QuickStartv20/aspnet/samples/data/GridViewMasterDetails_vb.aspx
I follow everything to the 'T' but for some reason all my data views are showing even before any initial selection is made in the drop down. How can I have certain grids appear only after a selection from another control has been made?
Thanks in advance,
Nick
Can someone please tell me what I am doing wrong... I have a simple webform that has contains a GridView and a DetailsView. Once the GridView is populated the user simply selects a record from the list. The DetailsView is them populated with all of the data from the selected record. The DetailsView is bound to a SQL DataSource/CustomerData. I have made sure that the DV control has the Edit/Update Command listed. The user can click the Edit button and successfully edit the fields but when the user clicks the "Update" button I am getting the following message. Updating is not supported by data source 'CustomerData' unless UpdateCommand is specified Why isnt the control handling the Update. Many Thanks!!!! T
I have 2 Gridviews and a DetailsView for each GridView. The first Gridview and DetailsView work fine and I can Insert, Delete and Update the DetailsView just fine. However the second Gridview/DetailsView will only let me Insert but not Delete or Update. When I click on the "Delete" button it just ignores me. If I do an "Edit", when I try to click on the "Update" button it is ignored again and I have to click on "Cancel". I don't get any error messages...
Hi, i have a listbox with multiple selection enabled, the end user uses this listbox to select what data they want to view eg. they select "green" to view all the green cars, "red" to select all the red cars etc. i have the listbox as the control that is connected to the datasource (the sql used for it is select * from cars_table where color =@colorthis works fine when one item in the listbox is selected, but when multiples are selected it does not work what format does the =@color have to be when multiples are selected? i've tried "green, red" "green + red" etc. but cannot seem to get it workingdoes anybody have any working examples that i can take a look at? it seems to be a common action, yet i cannot seem to find any documentation on how to get it to workthanks in advance!
I have a form where a user can select multiple items from a listbox control.How can I pass each item selected to a sproc? Do i need to created a paramter for each item in my listbox in my sproc?Has anyone done this, I dont want to create dynamic sql to handle this and i dont really want to create 100 parameters to handle my listbox items.thanks
I have a page where there are two gridviews and possibly will be more. I plan on only showing the selected gridview via a radio-button list and a multi-view control. I don’t really see the need to have a new sqldatasource for every gridview, so wanted to just have one and “rebind” the sqldatasource to the selected Gridview at runtime. i.e. when the suer clicks a radio button, I want to change the select command of the sqldatasource, execute the command and bind the results to the gridview.
A couple of questions though...
1) Is the above possible? I’ve tried changing the following but it doesn’t seem to work:
All I get is whitespace, no error, no emptydata text, but no gridview either?Any ideas what I’m doing wrong?
2) What is the overhead like of having multiple datasource objects such as multiple sqldatasource controls? Would It be better (simpler and more efficient in terms of page loading times) to have multiple sources?
Hi,I am using detailsview to update my database and got a question regarding datetime format. Here is part of my code: <asp:TemplateField HeaderText="Project Deadline"> <EditItemTemplate> <asp:TextBox ID="txtDeadline_edit" runat="server" Text='<%# Bind("pro_app_deadline") %>'></asp:TextBox> <asp:CompareValidator ID="txtDeadlineedit_validator" runat="server" ErrorMessage="Not a valid date format" ControlToValidate="txtDeadline_edit" Operator="DataTypeCheck" Type="Date"></asp:CompareValidator> </EditItemTemplate> <ItemTemplate><asp:Label ID="txtDeadline" runat="server" Text='<%# Eval("pro_app_deadline") %>'></asp:Label> </ItemTemplate></asp:TemplateField> Since the format of my parameter 'pro_app_deadline' is datetime, it get stored as YYYY-MM-DD hh:mm:ss in datebase. If I want to validate user's input like above way, it always fails since hh:mm:ss append to YYYY-MM-DD. My question is, is there some way I can avoid hh:mm:ss? Thanks a lot!
Hi everybody,I have a little Problem with an update and Detailsview.I have 2 table (tblUser - uid,uName,rId) and (tblRole - rId, rDescription) In my update I don't want to use the roles id, I want to use the roles Description.Via sql I do a update the role to Admin like that UPDATE tblUser SET rId = (SELECT rId FROM dbo.tblRoles WHERE (rDescription = 'Admin')) But I don't get it to work for the detailsview update

Hi I have a Page with a DetailsView and SqlDataSource. When Editing the DetailsView the Sql;DataSource UpdateCommand does not seem to pick up the @parameters of the form fields. I have used OnItemUpdating to view all Keys/OldValues/NewValues passed into the UpdateCommand but nothing seems to be picked up. When I place a value into UpdateCommand it updates correctly but does not when I use the form. At this stage I have simplified the code down to typical Master-Details Pages (Separate) using a QueryString to filter the SelectCommand. But nothing seems to work. Please help! I have wasted so much time trying to resolve this and I am on deadline and need this to work. Thanks Dave
Hello Am developing a web site using ASP.net 2.0. I have page to manage the employees information in term of viewing, inserting and updating. The problem is that the updating part doesn't work and it didn't give me any error messages. My code is as following: <%@ Page Language="VB" AutoEventWireup="false"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Hi,I'm trying to create a registration page that I've divided into multiple pages (first page for basic details, next page for address, etc.). I insert the record in the first page, and update it in the other pages. I pass the newly created ID to the other pages using the Page.PreviousPage property. In the second page, I have the SqlDataSource configured as "SELECT * FROM [Table] WHERE ID = ?", and the UpdateCommand is "UPDATE .... WHERE ID = ?". In Page_Load, I am updating the SelectCommand to "SELECT ... WHERE ID = " & intID, and the UpdateCommand similarly. The I do a dtlsvw.Databind()But when I go to the next page (the newly created ID is being passed properly), the update doesn't do anything. The new record doesn't contain the values in the detailsview. Can somebody help me out? Thanks,Wild Thing
For some reason I can't make the stars align. Could someone spot the problem here? I'm looking to select the Identity of my last inserted record in the code behind my DetailsView. Here are the relavent bits: Stored Procedure:ALTER PROCEDURE usp_EW_INSERTMajor @StartDate datetime, @Finishdate datetime, @ProjectName nvarchar(1000), @WorkCell nvarchar(1000), @JobName nvarchar(1000), @PartName nvarchar(1000), @StatusID int, @ResponsibleID int, @FacilityID int
AS Set nocount on
DECLARE @ProjectID int /*This saves the bits to the Project table*/ INSERT INTO EW_Project (ProjectTypeID,FacilityID,StartDate,FinishDate,Status,EmployeeID) VALUES(1,@FacilityID,@StartDate,@FinishDate,@StatusID,@ResponsibleID)
/*This saves the bits to the Major table*/
SET @ProjectID = SCOPE_IDENTITY() INSERT INTO EW_MajorBasic(ProjectID,ProjectName,WorkCell,JobName,PartName) VALUES (@ProjectID,@Projectname,@WorkCell,@JobName,@PartName)
Code-Behind: Sub DetailsView1_ItemInserted(ByVal sender As Object, ByVal e As DetailsViewInsertedEventArgs) Handles DetailsView1.ItemInserted Dim newID As Integer = e.Values("ProjectID") testlabel.Text = newID End Sub
To be clear, everything is working. When I come to this page with an ID, the records display fine (Select works). The Update and Delete work just fine. The Insert works fine too. It's just that the ItemInserted part does not want to grab the ProjectID. Specifically, testlabel displays a Zero.
I have been stuck on this problem for over a week, and have ripped out about all of my hair, so here it goes.
I am working on a portfolio on a website that administrators are allowed to update, but the public may only view....easy enough? The grid has three parameters; CatID, Descrip, and Pic - as seen below.
Now as I was looking around on the web I saw many people converting the path of the image to binary and the casting it to the DB, and likewise retrieving it from the DB as binary and converting it to an image, the problem is, I don't know how to do this.
Any help to ease my troubles is apprechiated greatly.
Edit: Also I am not totally sure what the '<%Eval("Pic") %>' is doing, it was autofilled for me. Edit again: Another thing, if I replace any of the ImageUrl to an image path on the computer it does fill the space in the gridview/detailsview. However, with both cases I get a Operand type clash: nvarchar is incompatible with image error.
Hi, any suggestions on why my label doesn't show the current user.identity.name when used in a detailsview (header-field or insert-field), when it works just fine placed directly on my page ?

I have a SQLDataSource bound to a DetailsView. In which event would I catch a Primary Key violation? Would be an event of the SQLDataSource or the DetailsView? And which particular event? A small example would be great. Thx.
Hi All, I am placing a Matrix inside the table control for grouping requirements,but when we export the report to the Excel, the contents inside the table cell are ignored. Is there any way to get the full report exported, as per the Requirement.Please help me with this issue.
Hi all,We're selecting data from our database, FirstName, LastName, MobileNumber etc.We're using the detaials view function to return it in a table upon selection. However all of the variables are returned as they are in the database, ie: without spaces. We tried putting in spaces by selecting "AS what ever", but MSSQL does not seem to like spaces.Any ideas?Thanks
I am attempting to setup a Master-Details with GridView/DetailsView but I can't seem to find any information on using a stored procedure that requires parameters with the SqlDataSource control. SelectCommandType specifies that you are using a stored proc. SelectCommand specifies the name of the proc, but I haven't found any information on how to pass a parameter to the stored procedure.Is it even possible or do I have to forget about using the DetailsView control altogether?
I've been playing around with the new data controls (DetailsView,FormView) and have been having problems when attempting to update a record that has a uniqueidentifier as its primary key.I get the error message: Object must implement IConvertible. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidCastException: Object must implement IConvertible.I gather this is because there is a bug that has propagated from the beta version.One suggested work around is from http://64.233.183.104/search?q=cache:GDjA62POtgcJ:scottonwriting.net/sowBlog/archive/11162005.aspx+Implicit+conversion+from+data+type+sql_variant+to+uniqueidentifier+is+not+allowed.+Use+the+CONVERT+function+to+run+this+query.&hl=en The crux of the problem, it appears, is that the <asp:Parameter> value for the uniqueidentifier field is, by default, set to Type=�Object�. To fix this, simply remove the Type property altogether. That is, change the SqlDataSource parameter setting from something like: <asp:SqlDataSource ...> <InsertParameters> <asp:Parameter Name=�UserId� Type=�Object� /> ... </InsertParameters></asp:SqlDataSource> to: <asp:SqlDataSource ...> <InsertParameters> <asp:Parameter Name=�UserId� /> ... </InsertParameters></asp:SqlDataSource> This change worked for me; once the Type was removed the exception ceased and the updates/inserts worked as expected.Unfortunately this only partially worked for me as while it is fine for deletes it won't work for updates.If anyone can help shed any light on this I would greatly appreciate it.CheersMark
UPDATE #2: When it said "Do you want to install Microsoft SQL Server" I said "yes" and that caused it to work. I exited and re-ran and now the print runs w/o the "install SQL Server" (If the prompt had said "Do you want to install the print dialog" we wouldn't be having this discussion...)
UPDATE: After posting this i discovered that the same thing occurs when attempting to print the report direct from IE6: First a dialog pops up "Do you want to install this software?" Name: Microsoft SQL Server. When I click "Don't Install" I get the dialog "unable to load client print control." Since this happens direct from IE6 I suspect it's browser settings. I'll resume tomorrow and post a followup.
My WinForm C# app integrates Reporting Services by calling them from WebBrowser controls. The problem is attempts to print cause a dialog: "unable to load client print control."
I've read prior posts that say "enable Active-X in your browser" - I don't know how to do that from a WebBrowser control.
Any ideas how to support Reporting Services "Print" from within a WebBrowser control?

Hi, First off, let me state that i am new to ASP.net... and have had to hit the ground running... I have looked on the net but have not found a suitable explanation on how to do this. Let me explain what i am trying to do: In my aspx page, i have 2 dropdown boxes where the user will select a skill catagory, and then a skill. Based on that selection, i would like to compute what the Service line will be. There is a primary and foreign key on CatID on the skills and SkillCat tables. This data would need to be inserted into the another table aswell, and this would need to go into a report later. How do i go about doing this? Some examples would be greatly appreciated. And if you know of a good link, please post it for me. Skills Table
