Hi friends ,

In our application we are binding grid on client side.
On binding the grid the records are not displying.I am not getting what's wrong in our code.
Bellow is the code i have written,

-----------------test.aspx -----------------------
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">      
 function pageLoad(sender, eventArgs) {          
          
           var tableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
           $find("<%= RadAjaxLoadingPanel1.ClientID %>").show("<%= RadGrid1.ClientID %>");
           PageMethods.GetData(0, tableView.get_pageSize(),
                tableView.get_sortExpressions().toString(), tableView.get_filterExpressions().toList(),
                    updateGrid);
                   
           PageMethods.GetCount(tableView.get_filterExpressions().toList(), updateVirtualItemCount);
       }
function updateGrid(result) {          
           var tableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
           tableView.set_dataSource(result);
           tableView.dataBind();          
 
           $find("<%= RadAjaxLoadingPanel1.ClientID %>").hide("<%= RadGrid1.ClientID %>");
          
        }
 function updateVirtualItemCount(result)
        {
           var tableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
           tableView.set_virtualItemCount(result);
        }
  function RadGrid1_Command(sender, args) {         
            args.set_cancel(true);                       
            var pageSize = sender.get_masterTableView().get_pageSize();
            var sortExpressions = sender.get_masterTableView().get_sortExpressions();
            var filterExpressions = sender.get_masterTableView().get_filterExpressions();           
            var currentPageIndex = sender.get_masterTableView().get_currentPageIndex();               
            if (args.get_commandName() == "Filter")
                currentPageIndex = 0;
            var sortExpressionsAsSQL = sortExpressions.toString();
            var filterExpressionsAsSQL = filterExpressions.toString();
            $find("<%= RadAjaxLoadingPanel1.ClientID %>").show("<%= RadGrid1.ClientID %>");
            PageMethods.GetData(currentPageIndex * pageSize, pageSize, sortExpressionsAsSQL, filterExpressions.toList(), updateGrid);         
          
        }
</script>

Hi,

I have a radcombobox which gets bind on the prerender event of the update panel which is its parent.

I have these properties set on the combobox
EnableLoadOnDemand="True"
ShowMoreResultsBox="True"
MarkFirstMatch="true"
EnableVirtualScrolling="true"
EmptyMessage="--- Choose ---"

After the initial load of the combobox the showmoreresultsbox does not show anything but just a dropdown arrow. After i type something in the combobox and when it filters it shows "Items 1-2 out of 2"

How can i get the text on the showmoreresultsbox on the initial load. I have these methods in my code behind file:

    Private Function GetData(ByVal test As String) As DataView
        Dim NewDataview As DataView

        NewDataview = DataViewTest

        NewDataview.RowFilter = "ElementName LIKE '" + test + "%'"

        Return NewDataview
    End Function

    Private Shared Function GetStatusMessage(ByVal offset As Integer, ByVal total As Integer) As String
        If total <= 0 Then
            Return "No matches"
        End If

        Return [String].Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", offset, total)
    End Function

    Protected Sub ddlElements_ItemsRequested(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs) Handles ddlElements.ItemsRequested

        Dim data As DataTable = GetData(e.Text).ToTable

        Dim itemOffset As Integer = e.NumberOfItems
        Dim endOffset As Integer = Math.Min(itemOffset + ItemsPerRequest, data.Rows.Count)
        e.EndOfItems = endOffset = data.Rows.Count

        ddlElements.Items.Clear()


        For i As Integer = itemOffset To endOffset - 1
            ddlElements.Items.Add(New RadComboBoxItem(data.Rows(i)("ElementName").ToString(), data.Rows(i)("GroupID").ToString()))
        Next

        e.Message = GetStatusMessage(endOffset, data.Rows.Count)
    End Sub

Hi,
I am using latest Telerik.Web.UI.dll (version 2012.1.501.40)
I have a RadScheduler and i set Height=100%

the scroll bar is showing on IE8
but not showing on Chrome and Safari Browsers.
Am i missing anything?
Please find the screenshot attachments.

I have inserted a scheduler within a multipage which is associated with the radtabstrip.

Although the scheduler will come on to the screen when I click on the second tab, the scheduler is only showing approximatley 100px of height, even though I have manually set the scheduler to have a height of 500px .  Because my document background is formated in grey I can see a large portion of white space where the whole scheduler should be being displayed(which would make up the 500px).

 When I click on the "24 hour" / "day" / "Month" views the scheduler then fills in the white space.

If I drag and drop the calendar out of the Multipage it works fine so is there a problem with the UI or is there further configuration that I am missing?

Thanks,

JK

Hi Telerik,

In my case, I want to show or hide any rows by clicking the link in template column in rad grid, click '+' to show the current row and '-' to hdie the current row.  And whatever the user chooses show or hide, keep the column that contians sign '+' and '-' to re-show and re-hide the current row. ( the UI is as shown below) How to achieve it? Look forward to your reply.

Thanks in advance.

We have a rather peculiar issue going on with the ajax loading panel.

First, the changes we did:

• We have upgraded from Telerik Q3 2010 to Q3 2011
• We have updated the solution from VS 2008 to VS 2010
• We have also updated the project to use the .Net Framework version 4.0 from 2.0
• The project is being published to a separate machine running on IIS 7 (previously was on IIS 6 on the same separate machine)
• We are using a 64 bit application pool with integrated mode (previously was 32 bit classic mode)

We are not sure what else we might be missing?

I have an odd issue w/ my ajaxmanager - whenever it updates something, i get some odd text next to the controls I indicated that it updated  - attached is a screenshot.


what am I doing wrong?

I have a page and clicking of a button opens a small RadWindow. Here the user makes some selections and clicks 'Generate' button. Now the server will start to stream a PDF file. Now radWindow.VisibleOnPageLoad = false does not work because the response stream is now PDF and not normal content type text/html

Is there a way to close the RadWindow in this case or is it a bug/limitation with Telerik RadWindow? 

Is the above possible ?

Essentially, i've got a collection of html anchor tags. I've set them to runat server and added their i'd to the target controls of the RadToolTipManager.

What i want to do is have each of these anchor tags cause an ajaxupdate request of the tooltipmanager and show the tooltip.
Each of the anchor tags has an id, which relates to an id in my database. I therefore want to query the database with this ID and pull out the appropiate information associated with the anchor tag.

The anchor tag enscapsulates an image, so if there's an easier way in which i should use a different control/element let me know.

Regards,

Alan
