int j=0 ; int n=GV.Rows.Count; for (int i = 0; i < 1 ; i++) { DropDownList dl = (DropDownList)GV.Rows[i].Cells[2].FindControl("ddlbudgetprd"); j = Convert.ToInt32(dl.SelectedValue); dl.Items.Clear(); TextBox tx1 = (TextBox)GV.Rows[i].Cells[4].FindControl("Txtbudgetamt1"); TextBox tx2 = (TextBox)GV.Rows[i].Cells[5].FindControl("Txtbudgetamt2"); TextBox tx3 = (TextBox)GV.Rows[i].Cells[6].FindControl("Txtbudgetamt3"); TextBox tx4 = (TextBox)GV.Rows[i].Cells[7].FindControl("Txtbudgetamt4"); TextBox tx5 = (TextBox)GV.Rows[i].Cells[8].FindControl("Txtbudgetamt5"); TextBox tx6 = (TextBox)GV.Rows[i].Cells[9].FindControl("Txtbudgetamt6"); TextBox tx7 = (TextBox)GV.Rows[i].Cells[10].FindControl("Txtbudgetamt7"); TextBox tx8 = (TextBox)GV.Rows[i].Cells[11].FindControl("Txtbudgetamt8"); TextBox tx9 = (TextBox)GV.Rows[i].Cells[12].FindControl("Txtbudgetamt9"); TextBox tx10 = (TextBox)GV.Rows[i].Cells[13].FindControl("Txtbudgetamt10"); TextBox tx11 = (TextBox)GV.Rows[i].Cells[14].FindControl("Txtbudgetamt11"); TextBox tx12 = (TextBox)GV.Rows[i].Cells[15].FindControl("Txtbudgetamt12"); if (j == 1) { tx1.Visible = true; tx2.Visible = false; tx3.Visible = false; tx4.Visible = false; tx5.Visible = false; tx6.Visible = false; tx7.Visible = false; tx8.Visible = false; tx9.Visible = false; tx10.Visible = false; tx11.Visible = false; tx12.Visible = false; } if (j ==2) { tx1.Visible = true; tx2.Visible = true; tx3.Visible = true; } else if (j == 3) { tx1.Visible = true; tx2.Visible = true; tx3.Visible = true; tx4.Visible = true; tx5.Visible = true; tx6.Visible = true; } else if (j == 4) { tx1.Visible = true; tx2.Visible = true; tx3.Visible = true; tx4.Visible = true; tx5.Visible = true; tx6.Visible = true; tx7.Visible = true; tx8.Visible = true; tx9.Visible = true; tx10.Visible = true; tx11.Visible = true; tx12.Visible = true; }

Hi one Selected index change event you need to rebind the Grid and hide the column or visible the column as per selected value.like.

1. Grid templeted set the visibility in column and bind with boolean values.
1. catch the event on dropdown.
2. apply the visibility column value and set the true or false.
3. bind the grid view again.
