使用主/详细方法时隐藏详细信息视图

Question

I am using a GridView that populates DetailsViews (master/detail method). When I click on Select in the GridView and display a DetailsView, that view remains displayed after I Select another row from the GridView and it displays another DetailsView. My question is: how can I display only one DetailsView at the sameone time???

So far I have:

protected void grdMonster_SelectedIndexChanged(object sender, EventArgs e)
{
    //grdMonster is GridView and "BookTitle" is datafield and pnlBooks is panel around BookTitle  
    //DetailsView
    if (grdMonster.SelectedValue.ToString() != "BookTitle")
        pnlBooks.Visible = false;
    else
        pnlBooks.Visible = true;
} 

It doesn't work! The BookTitle DetailsView doesn't display! }

Answer 1

Fixed it by accident. "BookTitle" needed to be in the DataKeyNames along with the following code (I added this code for something else):

protected void grdMonster_SelectedIndexChanged(object sender, EventArgs e) { string BookTitle = grdMonster.DataKeys[grdMonster.SelectedIndex]["BookTitle"].ToString(); sqlDV1.SelectParameters.Clear(); sqlDV1.SelectParameters.Add("BookTitle", BookTitle); dtv1.DataBind(); }

Not quite sure how that works, but it does.
