Hi vinodkpasi ,
You can get the cell value by ;
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) { GridViewRow row = GridView1.Rows[e.RowIndex]; string id = ((TextBox)row.Cells[1].Controls[0]).Text; Response.Write("You cancelled the edit operation for employee with id: " + id); GridView1.EditIndex = -1; BindGrid(); }Result :
Best Regards,

Use DataKeyNames
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) { string EmployeeID = GridView1.DataKeys[e.RowIndex].Values[0].ToString(); }Suwandi - Non Graduate Programmer

Please place below code in your grid cancel event :
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
TextBox id = (TextBox)row.Cells[1].Controls[0];
var data = id.Text;
Response.Write("You cancelled the edit operation for employee with id: " + data);
GridView1.EditIndex = -1;
BindGrid();
