How Do I Get The SqlDataSource To Look At The Textbox
Mar 6, 2006
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?
I enter a id in the textbox and based on that it give me a list of all entries in gridview that use that id.This works.But if I leave it blank it gives me nothing. I want to make it so if I leave it blank it give me all the id's.Do I have to modify the sqldatasource on pageload?
Hi, I wants to bind textbox with sqldatasource in c#.net so I am using following code and has following error... Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.Source Error:

Hi! I have a page (a search page) with sqldatasource, gridview and set of textboxes. The sqldatasource is using stored procedure with parameters. Using the visual wizard i'm associating the parameters with apropriate textboxes controls. It all works, like a charm. The problem arises when I input some dangerous code in any textbox , like ' or % . I'm having exception about unenclosed strings, generally info about the possibility of sql injection. I thought that using ControlParameters, any Parameter in fact is sqlinjection safe, but apparently it isn't. Does anyone know the right way of achieving my goal? It's very urgent.
I have a SQL database with 1 column in it.. it is a do not call registry for my office. I want to make a web application so our leads can go on the web and request to be put on the do not call list. problem is, if their number already exists, it gets a violation of primary key... Normal handling for this would be to do a select query based on user input, and if it exists in the database, tell them that, else do the insert query... Problem is, i cant seem to figure out how to bind the result of the select query to a textbox or label so i can compare the results to do that logic. Any ideas? This is in asp .net 2.0. Thanks! -Dan
I have a DataReader on a web page: <asp:SqlDataSource ID="ChangeInfoRecord" runat="server" ConnectionString.......... I want to display the value of one of the returned field in a text box. What is the correct syntax? I tried RolledFromDisplay.Text = ChangeInfoRecord("RolledFrom") but that isn't it.
I have a sqlDatasource with 3 parameters based on the input of 3 text boxes on the page. The datasource returns sales details for a company based on a from and to date. I am attempting to set the value of the 3 parameters in the Selecting event of the datasource control but I'm not getting any data back. If I set the values literally then I get data back. Also when I step through the code I can see the 3 parameters getting their values from the textboxes and the drop down list as they should. This is driving me insane as I'm new to .net and just can't see what is stopping me retrieving the data when using the form fields to set the datasources parameters. Below is the aspx and the code behind for the page. Thanks in advance for any help. aspx..... <%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="LabelSales.aspx.cs" Inherits="LabelSales" Title="Untitled Page" %><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"> <asp:SqlDataSource ID="SqlDataSourceSales" runat="server" EnableCaching="false" ConnectionString="<%$ ConnectionStrings:streetwisedigitalConnectionString %>" SelectCommand="DL_GET_SALES_BY_LABEL" SelectCommandType="StoredProcedure" OnSelecting="SqlDataSourceSales_Selecting" > <SelectParameters> <asp:Parameter Name="fromDate" /> <asp:Parameter Name="toDate" /> <asp:Parameter Name="label" /> </SelectParameters> </asp:SqlDataSource> <asp:SqlDataSource ID="SqlDataSourceLabels" runat="server" SelectCommand="select label_id, label_name from dl_label order by label_name asc" ConnectionString="<%$ConnectionStrings:streetwisedigitalConnectionString%>"> </asp:SqlDataSource> <div> <table> <tr> <td>Start Date: </td> <td> <asp:TextBox ID="FromDate" Runat="server" Width="70"/> <asp:Button ID="btnFrom" Runat="server" Text="..."

Beginner question, I know -- but in ASP.NET 2.0, I can't figure out (or find out) how to populate a TextBox with data from the db using a SqlDataSource control (without using a formview control)??? Any help would be greatly appreciated!!
Hi, it is few days I posted here my question, but received no answer. Maybe the problem is just my problem, maybe I put my question some strange way. OK, I try to put it again, more simply. I have few textboxes, their values I need to transport to database. I set SqlDataSource, parameters... and used SqlDataSource.Insert() method. I got NULL values in the database's record. So I tried find problem by using Microsoft's sample code from address http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.sqldatasource.insert.aspx. After some changes I tried that code and everything went well, data were put into database. Next step was to separate code beside and structure of page to two separate files followed by new test. Good again, data were delivered to database. Next step: to use MasterPage, very simple, just with one ContentPlaceHolder. After this step the program stoped to deliver data to database and delivers only NULLs to new record. It is exactly the same problem which I have found in my application. The functionless code is here:http://forums.asp.net/thread/1437716.aspx I cannot find any answer this problem on forums worldwide. I cannot believe it is only my problem. I compared html code of two generated pages - with maserPage and without. There are differentions in code in ids' of input fields generated by NET.Framework:Without masterpage:<input name="NazevBox" type="text" id="NazevBox" /><span id="RequiredFieldValidator1" style='color:Red;visibility:hidden;'>Please enter a company name.</span><p><input name="CodeBox" type="text" id="CodeBox" /><span id="RequiredFieldValidator2" style='color:Red;visibility:hidden;'>Please enter a phone number.</span><p><input type="submit" name="Button1" value="Insert New Shipper" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("Button1", "", true, "", "", false, false))" id="Button1" /> With masterpage:<input name="ctl00$Obsah$NazevBox" type="text" id="ctl00_Obsah_NazevBox" /><span id="ctl00_Obsah_RequiredFieldValidator1" style='color:Red;visibility:hidden;'>Please enter a company name.</span><p><input name="ctl00$Obsah$CodeBox" type="text" id="ctl00_Obsah_CodeBox" /><span id="ctl00_Obsah_RequiredFieldValidator2" style='color:Red;visibility:hidden;'>Please enter a phone number.</span><p><input type="submit" name="ctl00$Obsah$Button1" value="Insert New Shipper" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$Obsah$Button1", "", true, "", "", false, false))" id="ctl00_Obsah_Button1" />In second case ids' of input fields have different names, but I hope it is inner business of NET.Framework.There must be something I haven't noticed, maybe NET's bug, maybe my own. Thanks for any suggestion.
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.
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.

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..
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! :)

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.
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:
I have a report with parameters but I show the parameters in a combo box (drop down list) with the valid values only, so, I need a single text box that autocomplete what the user types, could you help me with this please?
Hi, A report that looks perfect in the report designer has a minor problem when rendered. The textboxs widen if data is in them. If they are empty they are the proper length.
Do anyone know how I can replace or Substitute the current value of a form textbox with another value.For example, the string "YES" appears on the textbox but hit the SAVE button I would like "TRUE" to be entered in the SQL Server database table. Thanks.
I want to display 1 million characters in a SQL Server Report's text box, but it is only showing 32000 charcters....how can I display all 1 million character without any truncation.
I'm having an issue where the Textbox in a RS Report (1 page) is not showing up. I have 4 reports all of which are basically the same except 1 or 2 different wordings however on all of them they are not showing up using http://localhost/reports . If i'm in Visual Studio and click on preview report I see everything just fine. But when I view online (pdf, html, excel) it does not show. The footer however shows up fine on all of them. Does anyone have a fix?
PS: The wierd thing is that on Production they are working but on the Test server they are not and nothing has changed. Both servers are running the same version of SQL 2005. I need to re-deploy the reports coming soon with changes but I am afraid that Production will stop working then.
