DataTable dt = new DataTable();
        
        DataRow dr = null;    
        dt.Columns.Add(new DataColumn("ItemNo", typeof(System.Int32)));
        dt.Columns.Add(new DataColumn("Description", typeof(string)));
        dt.Columns.Add(new DataColumn("Qty", typeof(System.Int32)));

this is the textbox declaration

TextBox box1 = (TextBox)ItemGv.Rows[rowIndex].Cells[1].FindControl("itemNotb");

                    TextBox box2 = (TextBox)ItemGv.Rows[rowIndex].Cells[2].FindControl("desctb");
                    TextBox box3 = (TextBox)ItemGv.Rows[rowIndex].Cells[3].FindControl("qtytb");
drCurrentRow = dtCurrentTable.NewRow();

                    drCurrentRow["ItemNo"] = box1.Text;
                    drCurrentRow["Description"] = box2.Text;
                    drCurrentRow["Qty"] = box3.Text;

Are you sure Cells collection itemas are numbered correctly? Collections usually number from 0, not 1. Try changing indexes, replacing
TextBox box3 = (TextBox)ItemGv.Rows[rowIndex].Cells[3].FindControl("qtytb");
with
TextBox box3 = (TextBox)ItemGv.Rows[rowIndex].Cells[2].FindControl("qtytb");

(and in previous lines as well)

Have you debugged your code?

I suspec that it is because you have forgotten that C# arrays are zero based, not one.
So a three element array would have the elements:

VB

myArray[0]
myArray[1]
myArray[2]

Rather than:

VB

myArray[1]
myArray[2]
myArray[3]

Change your numbers!

Solution 1

Check if you have valid rowIndex value. And your grid contains atleast 4 columns (as you have accessed cells[3]).
