How do I find the row index on a button click in a gridview?

Question

I have a gridview with a population of students. If there are reject reasons, a button appears in the last column of the gridview. When the button is clicked, I want to make a call to the database to get the reject reason codes. My button click event fires but I am having issues getting the row index or first name, last name in the row in which the button was clicked. How can I get the value of the cells where the button was clicked so I can pass those variables to the database?

Thanks!

My button code is:

                            <asp:TemplateField HeaderText="Incomplete Reason" >

Hi @RD , Welcome to Microsoft Q&A,

Updated:

If you want to get rowindex in Gridview of Asp.Net Web Form.

Try using GridView_RowCommand.

The official website has a good example.

How to use the RowCommand event to add the name of a customer from a GridView control to a ListBox control when a row's Add button is clicked

I showed how to use dataGridView1_CellClick to query various properties of the selected cell. In the example I show how to select only the type CheckBox.

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.ColumnIndex > -1 && e.RowIndex > -1 && e.RowIndex < dataGridView1.Rows.Count)
    {
        var dc = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
        //Determine whether it is a CheckBox column
        if (dc.Value is bool cellValue)
        {
            MessageBox.Show($"RowIndex:{e.RowIndex} ColumnIndex:{e.ColumnIndex} Value:{cellValue}");
        }
    }
}
