Question

i want a javascript code to hide/display a panel

The panel has a grid if the grid has data…then the panel should be displayed
and if the grid is empty then the panel should be hidden

I tried this code..but it does not work…

<script language="javascript" type = "text/javascript">
    var gridview = (document.getElementById("#<%= gridview1.ClientID %>")) ? true : false;
    if (gridview) {
        document.getElementById("Panel1").style.display = 'inline';
        }
    else {
  document.getElementById("Panel1").style.display = 'none';
    }
</script> 

Answer 1

Remove the # in document.getElementById("#<%= gridview1.ClientID %>").
