I have a GridView in which I'm redirecting to popup from bounded button click which has its row value from id.

But its throwing an exception:

index is out of range bigger than 127

I want to change type of index but its not working.

Here's my code:

protected void GridView1_OnRowCommand(object sender, GridViewCommandEventArgs e)
{
    int index = Convert.Toint16(e.CommandArgument);

    TextBox1.Text = GridView1.Rows[index].Cells[4].Text;
    TextBox2.Text = GridView1.Rows[index].Cells[5].Text;
    TextBox3.Text = GridView1.Rows[index].Cells[6].Text;
    TextBox4.Text = GridView1.Rows[index].Cells[7].Text;
    TextBox5.Text = GridView1.Rows[index].Cells[8].Text;
    TextBox6.Text = GridView1.Rows[index].Cells[9].Text;
}

Maybe something like this:

foreach (GridViewRow gvRow in gridview1.Rows)
{
    if ((int)gridview1.DataKeys[gvRow.DataItemIndex].Value == index)
    {
        gridview1.SelectedIndex = gvRow.DataItemIndex;
        break;
    }
}

Try this to find the index:

Option 1:

GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);

int index = row.RowIndex;

Option 2:

In your button in .aspx add:

CommandArgument='<%# Container.DataItemIndex %>'

And in .cs:

int index = e.CommandArgument;

Option 3:

Try it with ToInt32 instead of ToInt16:

int index = Convert.ToInt32(e.CommandArgument);
