raise event handler for image button

Jan 21st, 2009

I have created image button at run time. But I want to know when I will click on this button then its click function will get call.How to create click event of this image button.

I have tried

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
Function bindgrid()
{
Buttonname.click+-new ImageClickEventHandler(Buttonname_click);
}
 
Protected void Buttonname_click(object sender, ImageClickEventArgs e)
{
}
Function bindgrid()
{
Buttonname.click+-new ImageClickEventHandler(Buttonname_click);
}

Protected void Buttonname_click(object sender, ImageClickEventArgs e)
{
}

But it is working only when bindgrid function calls on every post back.otherwise not if bindgrid function is put under (!page.postback)

On page load do this

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
       //Creating Dynamic Image Button
        ImageButton objImageButton = new ImageButton();
        objImageButton.ID="dynImageButton";
        objImageButton.ImageUrl="Your Image URL";
        //Add Click event handler
        objImageButton.Click += new System.Web.UI.ImageClickEventHandler(dynImageButton_Click);
        form1.Controls.Add(objImageButton);
       //Creating Dynamic Image Button
        ImageButton objImageButton = new ImageButton();
        objImageButton.ID="dynImageButton";
        objImageButton.ImageUrl="Your Image URL";
        //Add Click event handler
        objImageButton.Click += new System.Web.UI.ImageClickEventHandler(dynImageButton_Click);
        form1.Controls.Add(objImageButton);

Your click function should be like this

protected void dynImageButton_Click(object sender, EventArgs e)
{
Response.Write("Inside Image Button Click");
}

but the problem is this function is not getting called if I am writing in Pageload the whole thing inside

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
]if(1Page.IspostBack)
{//Creating Dynamic Image Button
        ImageButton objImageButton = new ImageButton();
        objImageButton.ID="dynImageButton";
        objImageButton.ImageUrl="Your Image URL";
        //Add Click event handler
        objImageButton.Click += new System.Web.UI.ImageClickEventHandler(dynImageButton_Click);
        form1.Controls.Add(objImageButton);       //Creating Dynamic Image Button
        ImageButton objImageButton = new ImageButton();
        objImageButton.ID="dynImageButton";
        objImageButton.ImageUrl="Your Image URL";
        //Add Click event handler
        objImageButton.Click += new System.Web.UI.ImageClickEventHandler(dynImageButton_Click);
        form1.Controls.Add(objImageButton);
 
}
protected void dynImageButton_Click(object sender, EventArgs e)
{
Response.Write("Inside Image Button Click");
}
]if(1Page.IspostBack)
{//Creating Dynamic Image Button
        ImageButton objImageButton = new ImageButton();
        objImageButton.ID="dynImageButton";
        objImageButton.ImageUrl="Your Image URL";
        //Add Click event handler
        objImageButton.Click += new System.Web.UI.ImageClickEventHandler(dynImageButton_Click);
        form1.Controls.Add(objImageButton);       //Creating Dynamic Image Button
        ImageButton objImageButton = new ImageButton();
        objImageButton.ID="dynImageButton";
        objImageButton.ImageUrl="Your Image URL";
        //Add Click event handler
        objImageButton.Click += new System.Web.UI.ImageClickEventHandler(dynImageButton_Click);
        form1.Controls.Add(objImageButton);

}
protected void dynImageButton_Click(object sender, EventArgs e)
{
Response.Write("Inside Image Button Click");
}

Remove the if(!Page.IspostBack) form your code which is preventing your dynamic control from recreating during postback. Let the control be created on every subsequent pageload(or postback).

 Help with Code Tags
