Paging not responding to collapse of a Group

We too are concerned about the lack of an explanation of how to handle the collapse of a group in a paged grid. We've seen several references to dynamically updating the paging but are unsure exactly how to perform this.

We're about to decide between the Telerik and DevExpress controls - for several reasons we prefer the Telerik controls, but currently the DevExpress grid's handling of collapsed groups is driving us to use them. Not getting a general solution (or a fix/change to the standard behaviour) will prevent us from sticking with Telerik.

Looking forward to your response.

server double click event without the overhead of always posting back

Hello,

I need to fire code(move user to view the details of the record and do some other stuff) when the user double clicks on the grid.

Now the only way i was able to fire the server code was to enable .ClientSettings.EnablePostBackOnRowClick = true;
but this gives me the overhead of a single row click posting back and i do not want that behavior for obvious reasons.

is there a way around the this, or is this the best i can do?

thanks

J

Ajax postback of single dock

I have a portal-type application that allows the creation of various "portlets".

Each portlet consists of a dynamically created RadDock, which contains a dynamically created RadAjaxLoadingPanel and RadAjaxPanel, which contains a dynamically loaded user control (ascx).

Dock
|--RadAjaxLoadingPanel
|--RadAjaxPanel
|--UserControl

When the user control inside the dock initiates a postback the update panel works as expected, centering over the individual Dock.

However, when the Dock initiates the postback, say by clicking a DockCommand button, the RadAjaxLoadingPanel doesn't display.

So, my question is:

Is there a client-side way for the Dock to tell the control inside it to initiate an action?

This would actually be useful for other situations as well.

RadDatePicker MinDate error with lytebox.js include

Just thought I would post this in case anyone ever runs into the same error. It took me a while to isolate it. Apparently setting the mindate on a RadDatePicker when you include the lytebox.js file causes the following error:

this["get_" + _24[i]] is not a function

pProgrammatically created columns not filtering

Please help,

I have a grid with programmatically created columns, depending on what columns the user wants shown.

    
                                If column("DATA_TYPE") = "varchar" Or column("DATA_TYPE") = "nvarchar" Then 
        
                                    Dim boundcol As New GridBoundColumn()  
        
                                    boundcol.UniqueName = column("FullName")  
        
                                    boundcol.HeaderText = column("FriendlyColumnName")  
        
                                    boundcol.DataField = column("FullName")  
        
                                    boundcol.HeaderTooltip = boundcol.HeaderTooltip.ToString() + " - " + column("FullName") & " - " & column("Description")  
        
                                    boundcol.ReadOnly = Boolean.Parse(column("Readonly"))  
        
                                    gridServers.MasterTableView.Columns.Add(boundcol)  
        
                                    boundcol.SortExpression = column("FullName")  
        
                                    boundcol.Groupable = True 
        
                                    boundcol.GroupByExpression = column("FullName") + " Group By " + column("FullName")  
        
                                    boundcol.AllowFiltering = True

However I cannot get the filtering to work. The filter box is there and it allows me to enter a value, but it will go away and think about it and comes back with an empty filter box and nothing happens. It basically does nothing.

I have looked through all the properties of a bound column and can't see anything I havent set.

Thanks for your help, I love these controls :)

Hi Telerik,

            if (lnkbtnSupplierSearch != null)
            {
                RadToolTipManager1.ShowEvent = Telerik.Web.UI.ToolTipShowEvent.OnClick;
                RadToolTipManager1.HideEvent = Telerik.Web.UI.ToolTipHideEvent.FromCode;
                RadToolTipManager1.TargetControls.Add(lnkbtnSupplierSearch.ClientID, true);
            }

    {
        UpdatePanel panel = args.UpdatePanel;
        List<ISupplier> listSuppliers = DoSupplierSearch();

        Control cntrl = this.LoadControl("SupplierSearchResults.ascx");
        panel.ContentTemplateContainer.Controls.Add(cntrl);
        SupplierSearchResults supplierResultsCntrl = (SupplierSearchResults)cntrl;

Support Needed to overcome insufficient Mask Option Problem in RadMaskedTextBox

Hi,
I am using RadMaskedTextBox and trying to create a mask that matches both L.##.#.###.#.##.##.## and L.##.#.LLL.#.##.##.##.

Tree letters that I highligthed with green, can be both letters and numbers. As you seen above, I have to be sure that users will enter only Capital letters and wont be allowed to enter punctuations (. specially) to the highlighted part. So aaa is not a real solution for me. Do you have any idea about what I am suppossed to do now? I would appreaciate it a lot if someone could help me to find a mask.
Thanks,
Kind Regards
