Hi there,

I have a Radgrid with server-side databinding and an onneeddatasource-event. 
I want to change the pagesize dynamically in addiction to the mastertableview-size.
All looks good but when the TableView was updated with the new pagesize, i can't select the rows anymore...

The Script:
<script type="text/javascript">
    function GridCreated(sender, eventArgs) {
            //gets the main table scrollArea HTLM element  
            var scrollArea = document.getElementById(sender.get_element().id + "_GridData");
            var tvHeight = scrollArea.offsetHeight;
            var size = Math.floor(tvHeight / 64);
            //alert(size);
            var tableView = $find("<%= RadGridView.ClientID %>").get_masterTableView();
            tableView.set_pageSize(size);
    }
</script>

HTML-Code:
<telerik:RadGrid ID="RadGridView" AutoGenerateColumns="False" onitemdatabound="RadGridViewItemDataBound" OnItemCreated="RadGridViewItemCreated" AllowSorting="True" AllowPaging="True" EnableViewState="True" OnPageIndexChanged="RadGridPageIndexChanged" OnNeedDataSource="RadGridView_NeedDataSource" runat="server">
<PagerStyle Mode="NextPrev" Position="Bottom" AlwaysVisible="True" CssClass="RadGridPager" PagerTextFormat="Seite blättern: {4} Seite {0} / {1} - Einträge {2} - {3} / {5}"/>
<ClientSettings>
    <Selecting AllowRowSelect="true" />
    <Scrolling AllowScroll="true" UseStaticHeaders="true" SaveScrollPosition="true" />
    <ClientEvents OnGridCreated="GridCreated" />
</ClientSettings>
<MasterTableView TableLayout="Fixed" Font-Size="18px" ClientDataKeyNames="IsBlueLight,IsFailure,IsStopped,OrderNr,ObjectNr" DataKeyNames="OrderNr">
    <NoRecordsTemplate>
        <div>
            Keine Einträge
        </div>
    </NoRecordsTemplate>
    <Columns>
         .........
</telerik:RadGrid>

Code-Behind:
....
protected void RadGridView_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    RadGridView.DataSource = Session[Constants.ORDERLIST] as List<Auftrag>;
}
....


thanking you in anticipation

Best regards,
Markus

Hi Markus,

Note that this property is used with client-side data-binding. You cannot change the page size of a server-bound RadGrid on the client.
You could try the other way around - make the master table as high, as its fixed number of items currently are. For example, if you have a page size of 10 but the item height varies, you can use the following setting to make the grid auto-size to fit its content:
<ClientSettings>
    <Scrolling AllowScroll="true" ScrollHeight="" />
</ClientSettings>
