i tried for that also kiran...in that i got this error at same line when i took a string array..

like

Object reference not set to an instance of an object.

in this line

arr[i] = dataGridView1.Rows[i].Cells[3].Value.ToString();

you might have entered a no which exceeds the range of int
better store the mobile no as string itself
this will resolve your problem radhika

No row can be added to a DataGridView control that does not have columns. Columns must be added first.

am getting this execption in this line....
//this.dataGridView2.Rows.Add(dr);
