Simple Databinding With A Textbox ?
May 28, 2006
Hello,
I would like to databind a textbox (the Text property) and I have try the following syntax:
Text='<%# Bind("au_fname") %>'
but there's no Datasource property for this control. I have defined a SqlDatasource object but can I link it to my Textbox. I have looked at the properties of the control: there's a Expressions section in which I can configure a connection string but thar's all.
When I run the page I have no error but the textbox field is empty.
Thanks for your help.

hello...
Probably a simple question but I have to ask...using visual basic 2005 express...
I have two tables one with last name and basic info, one with detailed info. Both set up with Primary key and Foreign key.
I have a combo box that displays the last names and then by clicking
the last name, text boxes fill with the "other" data from table1,
however,
there are some text boxes that I would like to fill with data from the table2.
Any pointers??

I’m trying to teach myself C# and trying to create a simple (so I thought) little database using Infragistic's UltraWebGrid (Althought my question is more ASPish). Every sample I run across seems to only show the very basics and doesn’t seem to go into anything more than just a simple table and displaying it in a Gird. Which is pretty easy and I can do that all day and night.
Anyway, my database has three tables in a one-to-many relationship. The database is of Trucking companies and which states they service and they can service multiple states.
The database is like this:
Compnies:
TruckerID, Company Name, Address, etc.
ServiceStates:
TruckerID, StateID
StateNames:
StateID, StateName, StateAbbreviation
I would like to show the States that they service in a Hierarchical Grid.
I can write the SQL to do what I want to, basically do an inner join on ServicesStates and StateNames based on the TruckerID. I can sit all day and night getting what I would like to display in the WebGrid in the query builder on the SQL server. I figured it wouldn’t be much of a stretch to be able to do that in UltraWebGrid (Or whatever floats your boat).
Anyway, on to my question. :)
While browsing the samples on everything, I've figured out, that I will need to use the SqlDataAdapter Class, to access the database. Then I'll need to use the SQLConnection Class, and populate a DataSet.
Now while in VS I can go to WebSite -> Add New Item -> DataSet slap my tables on there and away I go (at least it seems that way). If I do that, what exactly is the difference between doing that and using the dataset class? When I do that, is that not creating the dataset? I see all the classes it created (I named mine Trucking). I see all the SQL statements in the classes.
I imagine I must be missing something *REALLY* simple or this just went way over my head at by at least 40,000 ft.
Thanks,
marly

Hi, I have a page created within VS 2005 which uses a detailsView with a SQLDataSource which has insert, edit and delete items allowed with it. The problem is that if I delete a record I dont want to refresh the page as I want to set a label value to say item deleted. The problem then though is to select the item to delete I have a drop down which populates the details view on index change, but if I delete the item I cannot do a databind when its complete because it just binds to the existing dataset and does not do a fresh call on the database.Is there a command I can run to refresh the dataset on click of the delete button?Thanks

Hey all,
I had a few questions about how to properly use the sqldatasource -
I have a form with a single dropdownlist, databound to an sqldatasource that just has a select statement. Over the course of time, the client has requested additional dropdownlists, all of which point to different sqldatasources. After I reached 4 or 5, I noticed the page started to load incredibly slower. I played around with the caching features, and after a good while of reading up on it, finally was able to cache the page /data and notice an increase.
Later, another 4 dropdownlists were added, 3 of which all take the same data. I assumed if I had 3 dropdownlists, which need the same data, I should use the same sqldatasource. What do you think? My page is behaving unaccepteably slow again.
As a test, I created a new page, and bound it in the same fashion. I slowly added more dropdownlists /sqldatasources, and found it lags a bit on the initial load time (maybe 10-12 seconds of processing time before the page loads). The tables it is pulling data from do not have a primary key, and i'm doing select statements that return roughly 100-200 rows of data (per dropdownlist on average). I'm only selecting 1 column name (no select * here)
I'm just curious if anyone has experienced similar issues, and also if there is anything I should do as a best practice while working with the sqldatasource. I've used hundreds of these on forms, and never experienced a problem. I only started noticing this on pages that have multiple. Also, when using multiple dropdowns that need the same data (I know that sounds goofy - why have 3 dropdownlists with the same data) should I use 3 individual datasources?
Thanks for your help in advance,
Mike

We are tired of null values coming out of from the database and we are directly coding behind UI decleratively.
We set up a null value coding standarts but I wonder what are the disadvantages to our approach
DataType The default value we send ALLOW NULL
int,bit,decimal 0 NOnvarchar(string) " "(one space) NOdatetime YESbinary YES
*in datetime we do not allow nulls in places such as _CREATEDATE and _LASTMODIFYDATE fields.
What are other approaches for null besides writing your own layer to handle it ?

Does anybody know a good way to get a (near) live view of a sqlce database that doesn't involve ResultSets? I tried to use a resultset with the Sensitive option set, but it doesn't like the joins that I have to do in order to have the data make sense to the user.
Thanks

I have a windows form containing some text boxes and radio buttons bount to an SQL Server database, with code like the following:
this.tbBorrowerLastName.DataBindings.Add (new Binding("Text", dsData.Tables["Results"],"BorrowerLastName"();
this.rbMale.DataBindings.Add(new Binding("Checked", dsData.Tables["Results"],"Male"))
If I add a new row and try to move there using the code below, nothing happens (neither movement to a new position nor error message), unless I remove the radio button bindings. (The same thing occurs if I attempt to move to any record that has a null value in the database field for a radio button).
myLastRow = dsData.Tables["Results"].NewRow();
dsData.Tables["Results"].Rows.Add(myLastRow);
I attempt to move by changing the value of the position property of the BindingContext object.
How can I retain the radio button bindings and still be able to add and move to a new row?
Any help would be appreciated.

Hello,
I have a page with a detailsview where I can add articles (Generated by visual studio). Now the table contains a field (Autor) wich must contain the username of the Autor from the article. But when I run my page now I have to give it in manually ( in a textbox). I've searching for a way to bind the Profile Username with the insert Sql Query, @Autor value.
I tought maybe I should insert the value of the Profile username in the textbox and put the textbox visibel on false.
But When i saw the component code I saw that Text= is already bound, so it's not possible to insert a value<asp:TextBox ID="auteurTextBox" Visible="true" runat="server" Text='<%# Bind("auteur") %>'> Here is whole the page code (line 23 is the textbox). 1 <asp:FormView ID="FormView1" runat="server" DataKeyNames="id" DataSourceID="SqlDataSource1" AllowPaging="True" CellPadding="4" ForeColor="#333333" style="left: 30%; position: relative">

Here's a new one I came across that stumped me for a bit.
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'xxxx'.
It appears that one of my dropdown menus was referencing the old SqlDataSource1for its data source id.
I had already changed the name of the of the id to something else though.
To fix it, I just updated the reference to the new name.
Thought I'd share, just in case

Hi,Seems like a lot of people are having a similiar problem that I am having right now, but I am not able to find the solution to it. On the Page_load event, the gridview does display the data from database. When I click a button to insert the same data but different Waste_Profile_Num value, it gives me the databinding error. Component_Profile_ID is declared as an Identity and it is the primary key to the table.

Hi!
I dont know if i will explain this correctly, but my problem is with reporting service.
I'm supposed to Sum value in one textbox and than that sum use it in sum in other textbox.
Something like this:
Sum(Fields!Abc.Value/(Fields!dfg.Value+Sum(Fields!abc.Value)),"matrix1_RowGroup1")*100
I get error msg 'The Value expression for the textbox 'textbox49' contains an aggregate function (or RunningValue or RowNumber functions) in the argument to another aggregate function (or RunningValue). Aggregate functions cannot be nested inside other aggregate functions.'
Something like this wont work either Sum(Fields!abc.Value/ReportItems("textbox56").Value)*100
Error The Value expression for the textbox 'textbox55' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers.
So, pls help if you know how to reference textbox in other in body of report.
Thx.

I am receiving funny results from a query. To simplify, I have 2 tables (todayyesterday). Each tbl has the same 8 columns. My query joins the two tables then looks where either of two columns has changed. What is happening is that when checking one of the columns it seems as though sql is flipping the column, causing it to be returned in error.
result set
colA colB colC colD colE colF colG colG (from yesterday)
1 1 a b c d e m
1 1 a b c d m e
So what's happening is that the record above is actually the same record and should not be returned. There is a daily pmt column that changes but I am not using that in the query. Aside from that the two records are identicle.
Any help is appreciated.

Hi,
I have the following situation (with a site that already works and i cannot modify the database architecture and following CrossRef tables -- you will see what i mean by CrossRef tables below)
I have:
Master table Hotel
table AddressCrossRef (with: RefID = Hotel.ID, RefType = 'Hotel', AddrID)
joins
table Address (key = AddrID)
table MediaCrossRef (with RefID = Hotel.ID, RefType= 'Hotel', MediaID)
joins
table Media (with MediaID,mediaType = 'thumbnail')
foreach hotel, there definitely is a crossRef entry in AddressCrossRef and Address tables respectively (since every hotel has an address)
however not all hotels have thumbnail image
hence i have hotel inner join AddressXReff inner join Address ..... however i must have
left outer join mediaXref left outer join media
the problem is that if there is no entry in Media or mediaXref, I don't get any results
i tried to get over it by using
where (media.mediaTyple like 'thumbnail' or media.mediaType is null)
but then i started getting multiple results for each hotel because media's of type movie or full_image or etc... all got returned
any clue?
thanks

Hey
I got a SQL DB with three tables, where two of the collums of the main table gets its data from two other tables, ok? Now, on one page, called "search" the user should be able to search in the DB, and on another page the user should be able to register some keywords, my question is how can the user register several keywords in the same textbox, using perhaps a ; as a separator between the words? I hope you understand what I mean..
Thx!

Hello
How do u update the datafield of a row using buttonClick in vb? I have a details view whereby it will display the username and timeleft once log in. currently the datafield, timeleft on one user in the database is null. I'm using sqldatasource.
Once log in, it will direct to this page where the user enters a code on the textbox and click the enter button. This will cause an update on the user's timeleft. But the code must not be entered to the database.
For eg. If code = 1111 then 'update timeleft = 60 The timeleft is in minutes. 60 will be stored as double in the user's row in the database. How do i do this?
Please help asap. Thanks! :)

I am working with a Detailsview. I am displaying information from a number of different tables, and so when I configure the datasource I have to specify a custom sql statement. I can get it to display the right columns, but I cannot seem to be able to use a where statement.
I am wanting to display the info in the Detailsview based on what is entered into a textbox, but I get an error when I try to add in the where statement. Can someone tell me what I am missing here?
Thanks

Hey guys, I am trying to create a report which features a lot of textboxes side by side, but I have the problem that even though they are the same size when the textboxes are placed side by side or above or below another textbox and then the preview tab is selected they often look different for example they may not be aligned correctly or the borders look thicker in different textboxes.
Is there a solution for this issue?
Many thanks.

Hi Folks,
I'm trying to assign multiple values to a textbox and I'm receiving an error. The error says, "The value expression for the textbox AcctName contains an error." The first value is account number and the second value is account name. An example follows:
1234 - SPC Travel Agency
My expression for the textbox contains the following:
=Fields!AcctNum.Value + ' - ' + Fields!AcctName.Value
Please help.
