Solution 1

You are creating textbox and assigning id As

MyTextBox.ID = "txtsno" + "" + ViewState["num"] + i;

but while finding textbox control in btnaddpopup_Click you are using
TextBox txtsno = (TextBox)panelserial.FindControl("txtsno");

Instead of that Try
TextBox txtsno = (TextBox)panelserial.FindControl("txtsno" + "" + ViewState["num"] + i);

The problem here is as you are creating the controls dynamicaly the dynamically created controls will be lost on Post Back.
So you can write a web method which insert the value into database.
call the webmethod from javascript on btnaddpopup click.

prasanna.raj 25-Jul-14 1:48am

ya your right but no need to write web method, i got the code...

private string GetValue(string ControlID)
{
string[] keys = Request.Form.AllKeys;
string value = string.Empty;
foreach (string key in keys)
{
if (key.IndexOf(ControlID) >= 0)
{
value += Request.Form[key] + ",";
}
}

return value;
}
