hiding the radgrid if no rows are bound

[Jeff]

If RadGrid.rows.count = 0 then
RadGrid.visible = False
else
RadGrid.visible = True
End If

is this possible?

Hi Jeff,

Try the following code snippet to achieve the desired scenario.

CS:

  protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
       int RowCount= RadGrid1.MasterTableView.Items.Count;
       if (RowCount == 0)
       {
           RadGrid1.Visible = false;
       }
       else
           RadGrid1.Visible = true;
  }

You can also go through the following help article.
Visible/Invisible conventions

Thanks
Shinu.

if i set a break point on this and comment out the if logic - i run the page - initally nothing is bound from an object datasource - it steps through it and i can mouse over to seee that rowcount = 0 - so far so good - when i select something from the tree view and step through it stops and i can determine that the rowcount = 27 - but that's only when the if logic is commented out - if i uncomment the if logic and select something from the tree view - it does not step through this block like it never gets called. I've tried it from both within the radajax panel and out of it. please advise.

protected

void RadGrid2_DataBound(object sender, EventArgs e)
{
    int rowcount = RadGrid2.MasterTableView.Items.Count;
    if (rowcount < 1)
    {
        RadGrid2.Visible = false;
    }
    else
    {
        RadGrid2.Visible = true;
    }

}

i also tried this in the prerender area as well - please advise

Hello Jeff,

How do you bind your RadGrid? Please see if you can move all RadGrid-binding code to the NeedDataSource event and only set the data source for the respective tree view item. Then implement the below code snippet in RadGrid's PreRender event. Please share with us your observations.

via the object datasource.

if i do this - it doesn't showand the event is never called

int RowCount= RadGrid1.MasterTableView.Items.Count;

if (RowCount == 0)

{

RadGrid1.Visible = false;

}

else

RadGrid1.Visible = true;

but if i do this - the event is called and a mouse over of count shows me a number greater than 0

int RowCount= RadGrid1.MasterTableView.Items.Count;

//if (RowCount == 0)

//{

//   RadGrid1.Visible = false;

//}

//else

// RadGrid1.Visible = true;
