Hello,

I created my own PagerTemplate as described here. 

Because the Grid only groups the shown rows on the page I decided to disable the Paging so the user can see all grouped rows.

Before I created my own PagerTemplate the disable function of the behaviour worked.

Here is the asp code:

<script type="text/javascript">
<!--
function Grid_Paging_PageIndexChanged(sender)
 {
 var grid = $find('<%=Grid.ClientID%>');
 var parentGrid = grid.get_gridView();
 var dropdownlist = document.getElementById("ctl00_cphMain_DataControl1_Grid_ctl00_ctl00_DropDownList1");
 //var dropdownlist = document.getElementById("<%=Grid.ClientID%>".concat("_ctl00_ctl00_DropDownList1"));
dropdownlist.options[parentGrid.get_behaviors().get_paging().get_pageIndex()].selected = true;
 }
function PrevButton_Click()
 {
 var grid = $find('<%=Grid.ClientID%>');
 var parentGrid = grid.get_gridView();
 if (parentGrid.get_behaviors().get_paging().get_pageIndex() > 0) {
 parentGrid.get_behaviors().get_paging().set_pageIndex(parentGrid.get_behaviors().get_paging().get_pageIndex() - 1);
 }
}
function NextButton_Click() {
 var grid = $find('<%=Grid.ClientID%>');
 var parentGrid = grid.get_gridView();
 if (parentGrid.get_behaviors().get_paging().get_pageIndex() < parentGrid.get_behaviors().get_paging().get_pageCount() - 1) {
 parentGrid.get_behaviors().get_paging().set_pageIndex(parentGrid.get_behaviors().get_paging().get_pageIndex() + 1);
 }
}
function FirstButton_Click() {
 var grid = $find('<%=Grid.ClientID%>');
 var parentGrid = grid.get_gridView();
 parentGrid.get_behaviors().get_paging().set_pageIndex(0);
}
function LastButton_Click() {
 var grid = $find('<%=Grid.ClientID%>');
 var parentGrid = grid.get_gridView();
 parentGrid.get_behaviors().get_paging().set_pageIndex(parentGrid.get_behaviors().get_paging().get_pageCount() - 1);
}
function IndexChanged() {
 var grid = $find('<%=Grid.ClientID%>');
 var parentGrid = grid.get_gridView();
var dropdownlist = document.getElementById("ctl00_cphMain_DataControl1_Grid_ctl00_ctl00_DropDownList1");
 parentGrid.get_behaviors().get_paging().set_pageIndex(dropdownlist.selectedIndex);
}
</script>

In the code-behind I have disabled the Paging behaviour in the GroupedColumsChanged event.

protected void Grid_GroupedColumnsChanged(object sender, GroupedColumnsChangedEventArgs e)
 {
 if (e.GroupedColumns.Count > 0)
 {
 Grid.Behaviors.Paging.Enabled = false; 
 } 
 else
 {
 Grid.Behaviors.Paging.Enabled = true;
 //Grid.Rows[0].Items.FindItemByKey(e.GroupedColumns[0].ColumnKey).Column.Hidden = false;
 } 
 }

Can I disable the paging on the client?
