Why are you adding the text box dynamically instead of declaring the text box in the item template of the control markup? See the reference to TemplateField here in the MS docs: http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.aspx[^]

To add the control you should be using the RowDataBound event (http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.rowdatabound.aspx[^]) like this: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e){ if(e.Row.RowType == RowType.DataRow){ txt = new TextBox(); strID = "textBox1"; txt.ID=strID; e.Row.Cells(1).Controls.Add(txt) } } Try recursively searching the result of : GridView1.Rows[i].Cells[j]. Instead of calling GridView1.Rows[i].Cells[j].FindControl(strTextId). Do a recursive search of each of the child controls like this: Control ctrl = GridView1.Rows[i].Cells[j]; TextBox txt = FindControlRecursive(ctrl, strTextId) as TextBox; if(txt != null){ //read the value of the text box } Where your recursive function looks like this: private Control FindControlRecursive(Control current, String textId){ Control result = current.FindControl(textId); if(result != null) return result; foreach(Control ctrl in current.Controls){ result = FindControlRecursive(ctrl, textId) if(result != null) return result; } return null; }
