Event not firing. Adding controls dynamically to UserControl
I am adding controls to the UserControl dynamically and
then loading the UserControl Dynamically.But I am facing
problem with firing of click event of one of the buttons
within the UserControl.It does not fire.
If I do the same thing in a aspx page instead of a user
control then the event fires perfectly.
Adding of dynamic control in the User control is being
done as follows:
Page_Load
{
///
///
//
Table tbl = new Table();
tbl.Width = Unit.Percentage(100);
this.Controls.Add(tbl);
TableRow tr;
TableCell td;
btnSkipReg.ImageUrl = "../Images/btn_skip_reg.gif";
btnSkipReg.ID = "btnSkipReg";
btnSkipReg.Style.Add("cursor", "hand");
tr = new TableRow();
td = new TableCell();
td.Controls.Add(btnSkipReg);
tr.Cells.Add(td);
tbl.Rows.Add(tr);
///
///
///
}
private void InitializeComponent()
{
this.btnSkipReg.Click += new
System.Web.UI.ImageClickEventHandler(this.SkipReg_ Click);
}
private void SkipRegistration_Click(object sender,
System.Web.UI.ImageClickEventArgs e)
{
string redirectURL = "OrderConfUI.aspx";
Response.Redirect(redirectURL, true);
}

Victor Garcia Aprea [MVP] #2 Re: Event not firing. Adding controls dynamically to UserControl
Are you dynamically loading and adding the usercontrol at runtime? Or are
you adding it at design-time? A common problem for controls not firing
events happens when they're added too late in the control lifecycle (ie.
after Load).

Hi Nitin,
Did you solved this?
Try changing the loading code to Init instead of Load and let me know if the
problem still persists,
