Check if script is registered in manager

Hello,

I have a situation where I'm registering scripts with the script manager. I'm wondering if there is a check to see if the script is already registered in the manager before adding it.

I'm using a single page design model and what is happening is scripts are being added to the page more than once.

I'm looking for a property of the script manager or ajax manager to be something like IsScriptSet or even some functionality to simple check to ensure scripts are already added and if so, don't add again, just ignore the registration with the script manager.

The big issue, to clarify, is that my page is getting bloated with duplicate scripts being registered when users interact with my single page interface to my website. Please Help me stop the bloat!! :) Getting away from the single page design is not an option, it's in stone at the moment, so we need a check.

I appreciate any advice or feedback. Thanks very much.

How to subscribe to animation ended event?

Hi!

When a Dock is collapsed (dock.set_collapsed(true)), I do some custom javascript where I calculate heights of docks in my dock layout. But when using animation (dock.set_collapsed(true, true)), my calculations gets incorrect since the animation is ended AFTER my calculation.
Is there any way of subscribing to an animation ended event so I can do my calculations when the animation has ended?

Regards

Dock

Progress Animation On Save Command using RadAjaxLoadingPanel

Hi

I have followed the instructions in this article to allow me to add a Save button to my toolbar which uses a RadAjaxManager to run some Javascript which causes a postback to the server.

When the user presses the Save button I want to display a "Saving ..." animation while the server side script is executing. Is there an example which shows how this can be achieved using the RadAjaxLoadingPanel and RadAjaxManager ?

Thanks

Steve

NullReference exception at GetChildScriptDescriptorsRecursive

Hi,

I'm using the RadGrid in WebUserControl EditMode, and I've dynamically added two dropdownlists (they are inherited extensions of the ASP dropdownlists) and one CascadingDropDown from the AjaxControlToolkit.
If I do this inside my edit user control, I get a NullReference exception, the stacktrace is here:
   at AjaxControlToolkit.ExtenderControlBase.GetScriptDescriptors(Control targetControl)
   at System.Web.UI.ExtenderControl.System.Web.UI.IExtenderControl.GetScriptDescriptors(Control targetControl)
   at Telerik.Web.UI.ProxyScriptControl.GetChildScriptDescriptorsRecursive(Control parent, ArrayList scriptDescriptors)

   at System.Web.UI.Control.RenderControlInternal(HtmlTextWriter writer, ControlAdapter adapter)
   at System.Web.UI.Control.RenderControl(HtmlTextWriter writer, ControlAdapter adapter)
[...]

The edit control works if I don't add the CascadingDropDown to the control tree, and everything works if I add it outside the grid.

What should I try?

Thanks,

   At.

Problems binding Grid to List of EntityObject-objects (Entity Framework)

I use problems binding RadGrid to Entity Framework-objects.

I have two tables:

User:
UserID
Name
Age
GroupID

Group:
GroupID
Name

In entity framework, i get two Entitytypes. First User with properties UserID, Name, Age and Navigation property Group. Entity set name is set to Users. Second EntityType is Group with GroupID and Name as properties, and a navigation property named Users pointing to a collection of User-entities.

To fetch all users and include the group i use the following code:

    
            private List<User> GetUsers()  
        
            {  
        
             var users = from u in entities.Users  
        
               .include("Group")  
        
               select u;  
        
             return users.ToList();  
        
            }

Binding the grid to the list of User-objects is no problem.

    
            Grid.Datasource = GetUsers();  
        
            Grid.Databind();

I add the following columns to the grid.

    
            <telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name" />  
        
            <telerik:GridBoundColumn DataField="Age" UniqueName="Age" HeaderText="Age" />  
        
            <telerik:GridBoundColumn DataField="Group.Name" UniqueName="Group" HeaderText="Group Name" />

All data is displayed, no problem yet.

I want the 3rd column to be a GridDropDownColumn instead. I tried to use a GridDropDownColumn, but it didn't work, all rows were blank:

    
            <telerik:GridDropDownColumn DataField="Group.Name" UniqueName="Group" HeaderText="Group" />

I read in another thread that GridDropDownColumn is mainly for DataTables, so i tries to use GridTemplateColumn instead, and it almost works.

    
            <telerik:GridTemplateColumn DataField="Group.Name" UniqueName="Group" HeaderText="Group">  
        
             <ItemTemplate>  
        
              <asp:Label ID="Label1" runat="server" Text='<%#Bind("Group.Name") %>'></asp:Label>  
        
             </ItemTemplate>  
        
             <EditItemTemplate>  
        
              <telerik:RadComboBox ID="EditGroupRadComboBox"  runat="server" />  
        
             </EditItemTemplate>  
        
            </telerik:GridTemplateColumn>

The RadComboBox is bound to data in ItemDataBound:

    
            if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode)  
        
            {  
        
             GridEditableItem editedItem = e.Item as GridEditableItem;  
        
             RadComboBox combo = (RadComboBox)editedItem.FindControl("EditGroupRadComboBox");  
        
             combo.DataSource = GetGroups(); //returns List<Group>  
        
             combo.DataTextField = "Name";  
        
             combo.DataValueField = "GroupID";  
        
             combo.DataBind();  
        
             combo.SelectedValue = ((User)editedItem.DataItem).Group.GroupID.ToString();   
        
            }

It works as expected, the groups are displayed in the RadComboBox, and the correct option is selected.

Now to the problem, how do I perform the update? I tried he following in ItemCommand-event, but the user-object contains the old values

    
            if (e.CommandName == "Update")  
        
            {  
        
             User user = e.Item.DataItem as User;  
        
            }

I looked at the following thread, with a similar problem: http://www.telerik.com/community/forums/aspnet-ajax/grid/radcombobox-in-gridtemplatecolumn.aspx
I tried to set SelectedValue='<%#Bind("Group.GroupID") %>', but i get an exception, saying Group.GroupID is invalid.

Kind Regards, Johan

[Solved] Keep expanded item

Hi,

In a hierarchical datagrid with two levels I am trying to keep the edited item expanded through

    
            Public Sub Command_Row(ByVal Sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) 
        
            If (TypeOf (e.Item) Is GridDataItem) Then 
        
            'do the stuff here 
        
            dtgProducts.ReBind() 
        
            e.Item.OwnerTableView.ParentItem.Expanded = True 
        
            End if 
        
            End Sub

Does anybody have a clue why this isn't working?
