Check Filesize Clientsite - CustomValidator

Hello,
I readed this article about checking the filesize on clientsite: http://www.telerik.com/help/aspnet-ajax/upload_howtoclientfilesize.html

Now I customized this code for my project:

    
            <script type="text/javascript"> 
        
             function checkUploadedFilesSize(progressArea, args) 
        
             { 
        
               if (!progressArea.confirmed && 
        
                   args.get_progressData().RadUpload.RequestSize > 10485760) 
        
                 { 
        
                   progressArea.cancelRequest();    
        
                 } 
        
              } 
        
            </script>

It work's, but how can I set a custom validator to "false" after I canceld the request to show the user an error message??

My cumstom validator looks like this:

    
            <asp:CustomValidator  
        
              ID="checksizevalidator" runat="server" 
        
              Display="Dynamic"> 
        
            The total size of the selected files is more than the limit. 
        
            </asp:CustomValidator>

Thanks in advance for your help.

Regards
Dirk

Pivot grid with Detail tables

I want to provide a defaultDisplay (during development) which will display a single row from a table in a vertical manner. I would like associated detail tables to be presented in the normal horizontal manner.
I've used the PivotGrid examples to display this row as though it is a form. I have autoassigned the columns so that it can display table A, B or C according to some value passed to the form. The data is all provided by a dataset with the appropriate relations set up. I would like Table A to also be able to display its table subA details (using A.Id = SubA.Id).
I programmatically define the detail table because there are various detail tables according to whether Table A, B or C is being displayed.
If I programtatically define the detail table, because the MasterDetailTable has been pivoted, I pick up the incorrect details for the masterKey Values. How can I access the correct values when rows and columns are switched?

Basically can I mix vertical and horitontal RadGrids?

Automatically close RadWindow after 2 seconds

I would like to be able to auto close a Rad Window after 2 seconds. (Everything works except for the auto close after 2000ms). I have tried the setTimeout like this:

function openQuickActionRadWindow(tabid,XModID)

{

var oWnd = radopen("/Default.aspx?tabid=" + tabid + "&xmfid=5&SkinSrc=[G]Skins/Blue-NCPP/Plain&xmid=" + XModID, "RadWindow3" );

oWnd.Center();

oWnd.add_close(RefreshGrid);

setTimeout(oWnd.Close, 2000);

}

but I get a javascript error: Object doesn't support this property or method.

The details:
Browser: IE 8
Version: 2009.3.1208.35

Thanks,
Joe

Can't switch tab's with an <applet> inside a RadPageView

Hi There

I have a page where I am using two tabs. Within the RadPageView I am loading UserControls.

UC1 is the first to focus, and I can't seem to get UC2 to focus at all.

Here is the ASPX with the tabs

    
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

            </div>

I can confirm that my Applet is configured properly, and it loads without issue. But the problem is that I cannot switch to the "Page Properties" tab.

Thanks in advance.

Upgrading Controls - Can NOT Replace

I just upgraded from v2008 to v2009 AJAX .NET controls.

I have a huge website that I developed using these older controls. I want to use the newer versions going forward, but if I place one on the page it tells me that the file already exists and asks me if I want to replace "Bin/Telerik.Web.UI.dll"?

If I select yes than none of my pages work with the older controls - it tells me "that the 2008 version blah blah could not be found". if I select no, than wouldn't I really just be working with the older libraries and not even using the new controls?

Export to Excel issue with Ajax

Hi, I have an Export to Excel button (image button) that sits inside an Ajaxified RadPageView and a mult-tabbed interface and as you guessed by the title, The excel file does not export even though the following code executes without error.

Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExport.Click
        Dim filename As String
        filename = Membership.ApplicationName.ToString & txtFirstName.Text & "_" & txtLastName.Text & "_" & lblmemberID.Text & "_OrderHistory"
        RadGrid1.ExportSettings.OpenInNewWindow = True
        RadGrid1.ExportSettings.FileName = filename
        RadGrid1.ExportSettings.ExportOnlyData = True
        RadGrid1.ExportSettings.IgnorePaging = True

        RadGrid1.ExportSettings.OpenInNewWindow = True
        RadGrid1.MasterTableView.ExportToExcel()

    End Sub

Does anyone know how I can keep the Ajax but have the export perform as desired? Thanks.

Custom paging

I am trying to customize the paging of the radgrid but i hit the dead end.

Inside the NeedDataSource event handler i have these two lines:

    
            RadGrid1.VirtualItemCount = Catalog.ItemCount(Me.txtSearch.Text.Trim, _ 
        
                                                                                txtRangeFrom.Text, txtRangeTo.Text, _ 
        
                                                                                IIf(cmbDepartments.SelectedValue <> "", cmbDepartments.SelectedValue, 0), _ 
        
                                                                                IIf(cmbCategories.SelectedValue <> "", cmbCategories.SelectedValue, 0), _ 
        
                                                                                0) 
        
            RadGrid1.DataSource = Catalog.GetProducts(Me.txtSearch.Text.Trim, _ 
        
                                                                                 txtRangeFrom.Text, txtRangeTo.Text, _ 
        
                                                                                 IIf(cmbDepartments.SelectedValue <> "", cmbDepartments.SelectedValue, 0), _ 
        
                                                                                 IIf(cmbCategories.SelectedValue <> "", cmbCategories.SelectedValue, 0), _ 
        
                                                                                 0, Me.RadGrid1.CurrentPageIndex + 1, 10)

But it seems i am missing something because when i move through the pages after 10 or 20 pages it appears empty althrough it says that there are more pages remaining.

Also when i add some search criteria it does affect the items shown up in the grid itself but not the pager which still refers to the previously counted items/pages.

For instance if i enter search term "test" and click the search button calling RadGrid.Rebind method it affects only the first page of the grid but the pager does not change at all.

Am i missing something e.g. maybe i should replace the code for setting virtualItemCount property in another event?

Thanks

Advanced Databinding produces duplicate columns

Ok I need a solution to a problem I keep running into. Basically, I want the edit and delete command columns to be the rightmost columns on my grid. However, when I use the advanced databinding technique, the edit and delete command options are in the leftmost columns.

I tried explicitly declaring my data columns in the <column> section of the masterTableView, but the only thing that does is cause the needDataSource event to duplicate the collumns.

Here is my grid declairation markup:

    
            <telerik:RadGrid ID="gvFirmInfo" runat="server" Width="550px"> 
        
                <MasterTableView

                    CommandItemDisplay="Bottom" CommandItemStyle-BackColor = "#D8D8D8" 
        
                    ShowHeader="true" ShowHeadersWhenNoRecords="false" NoMasterRecordsText="" 
        
                    HeaderStyle-Font-Bold="true" HeaderStyle-BackColor ="#D8D8D8" 
        
                    ItemStyle-BackColor="White" ItemStyle-BorderColor="#C9C4D1"  
        
                    ItemStyle-BorderStyle="Solid" ItemStyle-BorderWidth="1px"  
        
                    AlternatingItemStyle-BackColor="#E0E0E0" AlternatingItemStyle-BorderStyle="Solid" 
        
                    AlternatingItemStyle-BorderWidth="0px" AlternatingItemStyle-BorderColor="#FFFFFF" 
        
                    BorderColor="#C9C4D1" BorderWidth="1px" BorderStyle="Solid" 
        
                    GridLines="None"> 
        
                    <CommandItemTemplate>  
        
                        <div style="text-align: right; padding: 8px;">

                        <telerik:GridBoundColumn DataField="Country" HeaderText="Country"> 
        
                        </telerik:GridBoundColumn> 
        
                        <telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="columnDelete" 
        
                            ConfirmText="Are you sure you want to delete this record?"> 
        
                        </telerik:GridButtonColumn> 
        
                        <telerik:GridEditCommandColumn UniqueName="EditCommandColumn"> 
        
                        </telerik:GridEditCommandColumn> 
        
                    </Columns> 
        
                    <EditFormSettings> 
        
                     <!-- I have a custom edit form in here --> 
        
                    </EditFormSettings> 
        
                </MasterTableView> 
        
                <ClientSettings> 
        
                    <ClientEvents OnPopUpShowing="PopUpShowing" /> 
        
                </ClientSettings> 
        
            </telerik:RadGrid>

Here is my VB:

    
                Protected Sub gvFirmInfo_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles gvFirmInfo.NeedDataSource

                        gvFirmInfo.DataSource = ds 

                    Catch ex As Exception 
        
                    End Try 
        
                End Sub
