Solution 1

Quote:
'System.Web.UI.WebControls.TextBox' to type 'System.Web.UI.WebControls.Label'

So, somewhere you are converting a Label to TextBox.

Debug line by line and find out where exactly you are seeing this exception. Then you can actually update that line of code.

C#

Label Jc = (Label)GridView1.Rows[e.RowIndex].FindControl("Jc");
//UD is a textbox you can not convert it to label
//<asp:textbox id="UD" runat="server" text="<%#Eval("Unregister_demand_to_be") %>" xmlns:asp="#unknown">
//Label udt = (Label)GridView1.Rows[e.RowIndex].FindControl("UD");
//corrected code
Label udt = (Label)GridView1.Rows[e.RowIndex].FindControl("udt");

Label IW = (Label)GridView1.Rows[e.RowIndex].FindControl("IW");
Label SC = (Label)GridView1.Rows[e.RowIndex].FindControl("SC");
TextBox Jc1 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("Jc1");
//udt is a label you can not convert it to textbox

//TextBox UD = (TextBox)GridView1.Rows[e.RowIndex].FindControl("udt");
//corrected code
TextBox UD = (TextBox)GridView1.Rows[e.RowIndex].FindControl("UD");

TextBox iwt = (TextBox)GridView1.Rows[e.RowIndex].FindControl("iwt");
TextBox sct = (TextBox)GridView1.Rows[e.RowIndex].FindControl("sct");
