In these articles, here I am placing a Method for finding the event generator or you can say Page postback responsible Control in C#.
for example, if we want to know which control causes the Post back the page. you simply use this code.
Control cause = GetPostBackControl(Page); public static Control GetPostBackControl(Page page)
{
Control postbackControlInstance = null;
string postbackControlName = page.Request.Params.Get(“__EVENTTARGET”);
if (postbackControlName != null && postbackControlName != string.Empty)
{
postbackControlInstance = page.FindControl(postbackControlName);
}
else
{
// handle the Button control postbacks
for (int i = 0; i < page.Request.Form.Keys.Count; i++)
{
postbackControlInstance = page.FindControl(page.Request.Form.Keys[i]);
if (postbackControlInstance is System.Web.UI.WebControls.Button)
{
return postbackControlInstance;
}
}
}
// handle the ImageButton postbacks
if (postbackControlInstance == null)
{
for (int i = 0; i < page.Request.Form.Count; i++)
{
if (page.Request.Form.Keys[i] != null && ((page.Request.Form.Keys[i].EndsWith(“.x”)) || (page.Request.Form.Keys[i].EndsWith(“.y”))))
{
postbackControlInstance = page.FindControl(page.Request.Form.Keys[i].Substring(0, page.Request.Form.Keys[i].Length – 2));
return postbackControlInstance;
}
}
}
return postbackControlInstance;
}
