The users insert a number in the TextBox1 (eg. 5).In the Button1_Click funciont the code insert in the panel dinamically the RadionButtonList.Then the user select one of the 5 Items of the RadioButtonList, and click on the (created dinamically) Button "ReadChoice"
I have a listview which I would like to fill with self created user controls.But the problem is that the properties in the user control is not set. The usercontrols are displayed but the property values I enter is not set. Why is that?
Here is the aspx code.
[code]....
My users have "demanded" to have an export function to their gridviews, and since they're running from usercontrols there's no way to modify the response stream. My workaround is to create an aspx to run in a hidden iframe. To do that, and to make it modular, I'm trying to dynamically create everything from the querystring. This *seems* to work just fine until I bind my sqldatasource to the dummy gridview. I then get "Procedure or function 'xxx' expects parameter '@NumberResults', which was not supplied."
View 1 RepliesIve been playing around with the default ASP.NET web application template and the following code throws an exception:
Object reference not set to an instance of an object.when clicking the created button.
Note 1: The markup is just a blank page with a placeholder in it - see below.
Note 2: Substituting Button for LinkButton, and the code does not throw an exception and works.

I am having a gridview with an object datasource binded in the markup(aspx page).When page loads it directly works fine with all sorting and paging properties.However, i need to filter display on gridview so i have to change the datasource of the gridview on the code behindIt works fine.. i mean the filtering and displaying is good but paging and sorting doesnt work.
View 1 RepliesI've been manually adding the following line every time I create a new user control / web form in one of my ASP.NET web forms projects: Option Strict On. I can't just set it in web.config because it's a legacy project that has user controls / web forms that would bomb out if we turned on option strict for the entire site, so the current solution is to apply it to all new user controls / web forms and slowly update the older pages. Is there some sort of Visual Studio setting / template I can change so that "Option Strict On" is applied automatically when Visual Studio creates the codebehind files?
View 3 RepliesI have created button 2 below:
<input id="Button1" type="button" value="Stop"
onclick="alert('hello world');"/>
<input id="Button2" type="button" value="button" OnClik="alert('hello world');"/>
using a litteral tag on page load like this:
protected void Page_Load(object sender, EventArgs e)
{
Literal1.Text = "<input id="Button2" type="button" value="button" OnClik="alert('hello world');"/>";
}
Incredibly when testing in browser, click on button 1 works, not click on button 2 whereas the codes are the same !
I have been using LINQ to SQL for quite a while (about two years). Every thing was fine until now. As usual, I created LINQ to SQL classes and built the project, then created an aspx page. However, I cannot see the DataClassesDataContext in the code behind file. It is not listed in the intellisense list.
View 5 RepliesI just created an application in vwd2010. The software project defaulted to however vwd2010 ships. It tested fine on my system. I deployed it and it seems to be crashing because it says Codebehind instead of codefile. Why would Microsoft distribute vwd2010 so that it automatically creates and writes a codebehind file and automatically writes the header of the file to be "codebehind" but codebehind doesn't actually work in production. This is now a lot of work to fix and I don't even know if there is simply something I need to do on the server so that it will activate on "codebehind" instead of "codefile". I'm running asp.net 4 on the server.

What is the earliest time that a control can be focused on without causing an exception/server error? It seems that newly-created (in codebehind) controls cannot be focused on until they're added to the page (or another container on the page), but I'd like to confirm and make sure.

I have multiple questions about doing gridview in code behind.I used this code to fill my gridview at runtime.
[Code]....
My questions are:1. How to edit the column headers? When I bind the database to my gridview, obviously, the column headers of the database will be binded. For example "First_Name", I want to edit the column so I can omit the underscore.2. How to edit the column width?
Given the following code for a textbox in the EditItemTemplate of ListView:
TextBox txt = (TextBox)ListView.EditItem.FindControl("ImageURLTextBox");
How would we code for a textbox in the ItemTemplate of the same ListView?
I have a DDL bound to a sqldatasource where the dataTextName is the storeName (varchar) and the dataValueField is the storeID (PK Int). I'm holding the value of the storeID in a user's profile (using ASP.NET membership profile). So, when a user is created, they're assigned to a store (or not...it's optional). When I edit the user, I populate the DDL with all the stores in the table, but I need to set the selected item to the storeID in the profile (if it exists)...I'm not sure at what point to do it though. In my codebehind, I bind the ddl to the datasource and insert an additional item: if not page.ispostback then
REM: bind the company ddl
