Hi,

I have a Radgrid name grdActionList displaying data records.
I have a buttton as BtnAdd which, when clicked, opens a RadWindow which in turn has a NavigateUrl property set to AddData.aspx.

The AddData.aspx has a few textboxes and a "Add records" button named BtnAddRecords.
When the BtnAddRecords is clicked, the data from the textfields are stored in the DB and the RadWindow is closed.

How can I:

After the RadWindow is closed, the RadGrid is refresh / rebind.
All a message is displayed in the label just above the radgrid.

I have written a JS in the base page as to refresh the radgrid:

function OnClientClose()
{
$get("grdActionList").Rebind();
}

I have defined the RadWindow as:

<telerik:RadWindow ID="Window1" runat="server" EnableViewState="false" NavigateUrl="ActionPopup.aspx" Modal="true" Animation="Fade" VisibleStatusbar="false" Title="Manage Action" OnClientClose="OnClientClose" Behaviors="Close"></telerik:RadWindow>

This doesnot work!

Please help.

Thanks

Multiple control load approach

Hello!

I have a project with one treeview with checkboxes enabled. I also have a control, with just one property. What i need is to add control every time a node is checked, where the control property takes value from node value checked. It means if you check the first node, the control will be added. If you check a second one, than 2 controls will be shown, and so on. If you uncheck a node, of course the respective control should disappear.

Ok, i'm able to do this, by adding controls at runtime, but this means that every time a control is added or removed the whole zone (panel) will be refreshed. If already there are 10 controls this can take a long time (because this control has a grid inside).

I need an approach to add and remove this control without refreshing the whole panel. I don't know the best way for this... Maybe by adding (and removing) a panel for each control (inside a big panel)? Or is there any better way?

Thank you!

[Solved] How to set DatePicker Calendar attributes used in radgrid (inline) edit

Hello,

I need to set the calendar tooltips (to Dutch) of a DataPicker. The DataPicker is used within in an RadGrid.
I can set the attributes of the textbox, but I cannot set the attributes of the calendar control, that is, I can set them, but they are not used, the application shows the default values.

This is the relevant part of the aspx:

    
            <!-- snapshot from the RadGrid --> 
        
            <telerik:GridDateTimeColumn   
        
                DataField="Gebdatum" HeaderText="Geboorte datum" UniqueName="Gebdat" > 
        
            </telerik:GridDateTimeColumn>

And this is the code behind:

    
            Protected Sub FormatieRadGrid_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles FormatieRadGrid.ItemCreated  
        
                If (TypeOf e.Item Is Telerik.Web.UI.GridEditableItem AndAlso e.Item.IsInEditMode) Then 
        
                    'This is working  
        
                    Dim gebdat As Telerik.Web.UI.RadDatePicker = CType(CType(e.Item, Telerik.Web.UI.GridEditableItem)("Gebdat").Controls(0), Telerik.Web.UI.RadDatePicker)  
        
                    gebdat.Width = 80  
        
                    gebdat.tooltip = "geboorte datum" 
        
                    gebdat.EnableTyping = False 
        
                    'This does work as it gives no exceptions, but the code seems to be ignored   
        
                    Dim cal As Telerik.Web.UI.RadCalendar = CType(gebdat.FindControl("calendar"), Telerik.Web.UI.RadCalendar)  
        
                    cal.ToolTip = "Toon kalender popup" 
        
                    cal.FastNavigationSettings.EnableTodayButtonSelection = False 
        
                    cal.FastNavigationStep = 12  
        
                    cal.FastNavigationNextToolTip = "volgend jaar" 
        
                    cal.FastNavigationPrevToolTip = "vorig jaar" 
        
                    cal.NavigationNextToolTip = "volgende maand" 
        
                    cal.NavigationPrevToolTip = "vorige maand" 
        
                    'The calendar control still shows its defaults values in stead of the adapted ones    
        
                End If 
        
            End Sub

What am I doing wrong / why doesn't this work as expected?

Regards,
-Ruud.
