Question

I have a GridView and a select link in the GrdiView, when the item is selected I want it to read the contents to a textbox below the GridView. The only way I can think is by accessing the behind code for the onClick function of the select link. The problem is I am unsure how to do this.

UPDATED jams method:

C# code

protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
    GridView1.SelectedIndex = e.NewSelectedIndex;
    TextBox1.Text = GridView1.Rows[e.NewSelectedIndex].Cells[0].Text;
}

front code

<asp:GridView ID="GridView1" OnSelectedIndexChanging="GridView1_SelectedIndexChanging" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" 
GridLines="None">

UPDATE my method:

protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
    int i = GridView1.SelectedIndex;
    ds.Tables["Comments"].Rows[i]["Comment"] = TextBox1.Text;
}

also tried this but I get an error -> System.IndexOutOfRangeException: There is no row at position -1.

Thanks.

You need to attach OnSelectedIndexChanged event with your gridview

<asp:GridView OnSelectedIndexChanged="GridView1_SelectedIndexChanged" />

Then in code behind you could do:

void GridView1_SelectedIndexChanged(Object sender, EventArgs e)
  {

    GridViewRow row = CustomersGridView.SelectedRow;// you will get the selected row
    someLabel.Text =  row.Cells[0].Text;
  }
