}推荐答案
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);
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);
