Hi,
We have looked into the source code and unfortunately the overflow:hidden is hard coded. So there is no way to turn that off. What you can do is to use a ContextMenu control instead of a ComboBox to do the selection it will be something like this:
Code: HTML/ASPX
<!-- The options should be defined as context menu item -->
<eo:ContextMenu runat="server" id="Menu1"
ClientSideOnItemClick="filter_selected"
....>
....
</eo:ContextMenu>
<!-- The Grid -->
<eo:Grid ...>
....
<Columns>
....
<eo:StaticColumn HeaderText="<div onclick='return select_filter(event);'>header</div>">
</eo:StaticColumn>
....
</Columns>
....
</eo:Grid>
Code: JavaScript
//This function is being called when user clicks on the
//header and it displays the context menu
function select_filter(event)
{
return eo_ShowContextMenu(event, "Menu1");
}
//This function is being called when user selects an item
//from the context menu
function filter_selected(e, eventInfo)
{
//Change this line to carry out your filtering process
alert(eventInfo.getItem().getText());
}
The key is the GridColumn's HeaderText is set to:
<div onclick='return select_filter(event);'>header</div>
Which triggers select_filter JavaScript function when clicked, which displays the context menu.
Hope this helps. Please feel free to let us know if you still have any more questions.
Thanks!
