Calling a functon in code behind by using an imagebutton in a gridview

Question

I have an ImageButton within a GridView in .aspx on clicking this ImageButton i have to call a function. This is how i tried and

Answer 1

Sure it won't be fired because it is nested in a Hyperlink. So the imagebutton serves as the text for the hperlink and hyperlink does not cause postback. ImageButton can cause the desired action only if it stands out of the Hyperlink. Try this:

ImageButton can do the job no need for Hyperlink just use the postbackurl and it will redirect you to the page. You can omit the HyperLink. Button controls (like LinkButton,ImageButton and Button) are designed to cause postback by default.

Edit: Make sure event name and arguments are correct. This is the event I used to test it. y the way don't forget to place the ImageButton in a TemplateField, refer the code above

protected void DeleteUrlImageButton_Click(object sender, ImageClickEventArgs e)
{
    TextBox5.Text = "Fired ";

 //Response.Redirect( ((ImageButton)sender).PostBackUrl);//uncomment this if the button does not automatically redirects. This line should be the last one 
}
