Hi

Grid dynamically fill data, the dynamic Aggregate add dynamic columns, the problem starts here. No problem when a single group, multiple groups is by attaching the calculations do not understand the results.

<telerik:RadGrid ShowFooter="True" ID="RadGrid1" runat="server" AllowFilteringByColumn="True" AllowSorting="True" GridLines="None" ShowGroupPanel="True" Skin="Web20" PageSize="15">

<MasterTableView ShowGroupFooter="True" GroupLoadMode="Client" CellSpacing="-1"></MasterTableView>

<ClientSettings AllowDragToGroup="True"></ClientSettings>

<ExportSettings OpenInNewWindow="True" ExportOnlyData="True" FileName="DataExport"></ExportSettings>

</telerik:RadGrid>

Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles RadGrid1.ColumnCreated

If e.Column.DataType.Name = "DateTime" Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).DataFormatString = "{0:dd/MM/yyyy}"

End If

If e.Column.DataType.Name = "Decimal" Or e.Column.DataType.Name = "Double" Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).DataFormatString = "{0:N3}"

CType(e.Column, Telerik.Web.UI.GridBoundColumn).Aggregate = Telerik.Web.UI.GridAggregateFunction.Sum

End If

If e.Column.ColumnType = "GridBoundColumn" And counteklendi = False Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).Aggregate = Telerik.Web.UI.GridAggregateFunction.Count

CType(e.Column, Telerik.Web.UI.GridBoundColumn).FooterText = "Total : "

counteklendi = True

End If

End Sub

[Solved] Heirarchical Binding

Hi,

I have two columns available for creating a heirarchical treeview:

PositionNumber ReportsTo

10030 10004

10122 10030

10838 10030

10923 10030

11015 10030

11229 10030

11422 10030

11453 10030

When binding, I get the error "These columns don't currently have unique values".

I understand the error. There are two '11015' PositionNumber values. These are two distinct records thast have the same position number... How can I make my treeview use the values as set out above?

Actually, I don't care what the control is just so long as I can view my data heirarchically presented. If another control is more suited, do let me know!

Thanks,
Richard

RadListBoxItemCollection client API issue with forEach when using IE 8

I have the following javascript function for the OnClientTransferred event of a RadListBox. This function works fine with Firefox and Chrome but I get a javascript error with IE 8.
Here is my javascript.

    
                 <telerik:RadCodeBlock ID="RadCodeBlockMain" runat="server"> 
        
            <script type="text/javascript"> 
        
                       function OnClientTransferredHandler(sender, e) { 
        
                           var myitems; 
        
                           var radbox = $find('<%= CurrentlyTransferredValues.ClientId %>'); 
        
                           var radbox2 = $find('<%= SourceListBox.ClientId %>'); 
        
                           myitems = e.get_items(); 
        
                           myitems.forEach(function(item) { radbox.set_value(radbox.get_value() + item.get_value() + ","); }); 
        
                           radbox2.set_value(e.get_sourceListBox().get_id()); 
        
                       } 
        
             </script> 
        
               </telerik:RadCodeBlock>

The error from IE 8 is the following.
"Microsoft Jscript runtime error: Object doesn't support this property or method"
It seems to fail at line with the forEach statement.

Thanks in Advance

Change to RadTabStrip's RenderSelectedPageOnly property causing problems

In release 2011.1 519 an issue was fixed according to Telerik's release notes: Fixed: RadMultiPage: RenderSelectedPageOnly property was applied multiple times and too early in the Page Lifecycle, setting non-selected PageViews to Visible=false and causing troubles persisting state of some of the controls inside the views

This change seems to be causing me problems now.
It seems that the PageView only becomes visible now very late in the cycle! During Page.LoadComplete the selected page view seems to still be invisible, only becoming visible by PreRender.

This is making it difficult to deal with child controls of the PageView as the controls appear to be invisible until Page.PreRender, by which stage it is often too late to handle certain tasks.

Can you confirm this is correct?

The old behaviour wasn't causing me problems (as far as I am aware). Perhaps I could work around these new changes by manually setting the PageView to visible in my own code. Do you know of any workaround?

RadWindow is not displayed

Hello,

To test your RadWindow component for ajax, asp.net, i have create a page and did the same thing at the following exemple: http://demos.telerik.com/aspnet-ajax/window/examples/default/defaultcs.aspx. But i didn't get the same result: I don't have any window display in my page!
I have taken a look at "http://www.telerik.com/help/aspnet-ajax/window-overview-migrating-from-classic-to-prometheus.html" to see if there is any step missed. The explaination was not so clear to me since the links redirect to an error page "http://www.asp.net/ajaxlibrary/act.ashx".

You may have an idea about the origin of this problem. Thank You for help.

[Solved] LoadControl, updatepanel and postback

Hi,

I use LoadControl in CodeBehind, like this: RadMenuItem.Controls.Add(LoadControl("/login.ascx"));

It work out fine, and my login control are now inside r.a.d.menu.

BUT - if /login.ascx fail to login, I would like the r.a.d.menu item to open again and show the user, that a login problem occurred.

AND - if I implement an UpdatePanel in my /login.ascx file, it will fail with:
Cannot unregister UpdatePanel with ID '' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
Parameter name: UpdatePanel

Does anyone have solutions to these problems?
