I've created a custom control in ASP.NET for showing a pop-up message box. In my MessageBox class, I have a Content property as ITemplate like the following:
[PersistenceMode(PersistenceMode.InnerProperty)]
[TemplateContainer(typeof(MessageBoxContent))]
[TemplateInstance(TemplateInstance.Single)]
public ITemplate Content { get; set; }
I used my custom control in my page like this:
<cc1:MessageBox ID="MessageBox1" runat="server">
<Content>
<asp:Button Text="Save" runat="server" ID="B_Save" />
</Content>
</cc1:MessageBox>
Even I set the the Content property's TemplateInstance to Single, I still can't have access to the Button control.
All I want to do is to handle the click event of the button. When I assign an event handler to the button control and run the project, it throws a NullReferenceException.
I have a blank user control (child) and during Page_Load i create some text boxes and a button. I also add an event to the button.
I then load that user control dynamically from a placeholder in another usercontrol (parent). Both controls are rendered correctly but when i click on the button, the event isnt fired. how to handle the event?
Child code:
[code].....
If i use the child control directy (ie without the parent the control) the click event is raised and handled nicely. But when i use the parent control, the debugger wont even hit a breakpoint inside UpdateButton_Click().
Using a listview control for the first time... I need a button for each item, and of course I need to handle the click event for the buttons... upon clicking a particular button I of course need to know which item the button is associated with so the appropriate action can be taken...
In VS, I can't select the button and see my list of available events in the properties window like is normally done for controls outside of templates like this... what do I need to do?
I have to click twice on button control to fire an event.
View 6 RepliesBackground: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.
Example of Button Definition (within GetAdministrationInterface)

View 1 RepliesOn grid RowDataBound based on some condition i've added imagebutton dynamically. parallelly i want to add event for this button click. here is my code snippet.
protected void GV3_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TableCell cell = new TableCell();
ImageButton bttn = new ImageButton();

That message popup box comes, but i'm unable to catch that click event. while click on a row i want to delete that row, so want to create event dynamically. for that i've used this following dynamic click event
bttn.Click += new ImageClickEventHandler(b_Click);
private void b_Click(object sender, EventArgs e)
{
//delete record
}
but this above code also not working.
