事件不触发？

Question

I want to create an imagebutton in code behind like this:

ImageButton img1 = new ImageButton();
img1.CssClass = "stylImage";
img1.ImageUrl = @"~/images/Workflow/esign.jpg";
img1.AlternateText = "Signature";
img1.CommandName = "edit";
img1.Click += new ImageClickEventHandler(Image_OnClientClick);
img1.Command += new CommandEventHandler(Image_OnCommand);
workdesk.Controls.Add(img1);

The button create and display on page, but none of the click or command event fire.
There is no error or exception too.

Any ideas?!?

Your code works fine and both the events fires perfectly as I tested.

There may be a chance that you have not specified the Event Definition correctly.

Please recheck the below code which works like a charme..!!

protected void Page_Load(object sender, EventArgs e)
{
    ImageButton img1 = new ImageButton();
    img1.CssClass = "stylImage";
    img1.ImageUrl = @"~/images/Workflow/esign.jpg";
    img1.AlternateText = "Signature";
    img1.CommandName = "edit";
    img1.Click += new ImageClickEventHandler(Image_OnClientClick);
    img1.Command += new CommandEventHandler(Image_OnCommand);
    form1.Controls.Add(img1);

}

protected void Image_OnClientClick(object sender, ImageClickEventArgs e)
{
    //some code...
}

protected void Image_OnCommand(object sender, CommandEventArgs e)
{
    //some code...
}

This may help you..!!
