In Gridview, I want to capture the Column Id's value for the selected Row

问题

In Gridview, I want to capture the Column Id's value for the selected row. When I click "Select" and Click "Go" button, I receive this output:

Captured: MainContent_GridView1

How do I select the ID of that particular row?

protected void btnGo_Click(object sender, EventArgs e)
{
    try
    {

        GridViewRow row = GridView1.SelectedRow;

        String RowID = row.ClientID;


        Response.Write("Captured: " + RowID);


    }
    catch (Exception ex)
    {
        Response.Write("Error:"+ ex.ToString());
    }
}

One way to get the field values in a row is to add the field names to the DataKeyNames of the GridView:

<asp:GridView ID="GridView1" runat="server" DataKeyNames="Id,Phone" ... >

In code-behind, you can get the values this way:

int Id = (int)GridView1.DataKeys[row.RowIndex].Values["Id"];
string phone = (string)GridView1.DataKeys[row.RowIndex].Values["Phone"];

I included Phone in the list to show that several fields can be specified. In your case, DataKeyNames would only contain Id.

I think this is what you mean, you have a GridView that is showing the id in one of the columns. So, if it was the first column, you could do something like

GridViewRow row = GridView1.SelectedRow;
string id = row.Cells[0].Text;

Is that what you mean?

String Id = GridView1.SelectedRow.Cells[0].Text
