Need more details. Just debug it. It may be that FooterRow is null or it may be that TxtCustId is not found. Just use your watch window or your immediate window and you should be able to solve this very quickly.

Hi,

You should use some bullet proof solution. Check my previous answer[^] for similar problem...

Ra Selector class[^] is great thing to find/get controls on server side...

Most likely is that the control id is misspeled (case sensitivity also).Check piece by piece in debug.
Gridview1.FooterRow is not null and then Gridview1.FooterRow.FindControl("TxtCustId")) is not null. Based on that please see what is wrong.
Also make sure the control is available at the time of calling (is created). For eaxample if you try to call it on preinit the control is not created yet.

Solution 3

System.Web.UI.WebControls.TextBox txtBxText = (System.Web.UI.WebControls.TextBox)gridView.Rows[j].Cells[i].FindControl("txtbxID");

C#

Remember to loop through or give correct value of i and j
