Datagrid empty data hides header

[Roby Eisenbraun Martins]

Hi,

I have a gridview (NET 2005) and when it hasn't got values it shows a
nice "Not found" text message. But unfortunately all the gridview lay-out
hides( header, ... ).
Is there a property to keep the gridview visible even if the data is
empty?

Thank you,
Roby Eisenbraun Martins

Hi Roby,

I found in both ASP.NET 1.1 and 2.0 that you cannot do that except by having
another table (with its visible attribute set to false) on the page then upon
databinding you would set visible = true when the datasource is null, e.g.

protected void GridView1_DataBinding(boject sender, EventArgs e)
{
GridView gv= (GridView)sender;
DataView dv = (DataView)gv.DataSource;
//if you are using a Business Logic Layer then replace the prevous line with
//equivalent type casting
MyEmptyTable.visible=true; //this is the table that you left to display
if there were no data

}

I missed the line that checks for the dataview is null, e.g.

if (dv == null) {
MyEmptyTable.Visible=true;
GridView1.Visible = false;
}
