FilterTemplate filter value remains "All"

http://www.telerik.com/help/aspnet-ajax/radgrid-filter-template.html
The first time run it's correctly displaying "All", after I select a different dropdown item, the grid filters correctly, but the FilterDropDown still indicates "All". How do I make it display the value that was selected?

Update: It works now after I change it to use the client side version of example:

OnClientSelectedIndexChanged="TitleIndexChanged" SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Application").CurrentFilterValue %>'

The Server side still has the issue:

    
                                <FilterTemplate> 
        
                                    <telerik:RadComboBox runat="server" ID="FilterCombo" DataSourceID="srcApplication" AppendDataBoundItems="true" 
        
                                    DataValueField="Application" DataTextField="Application" AutoPostBack="true" 

                                    SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Application").CurrentFilterValue %>'

                                    OnSelectedIndexChanged="FilterCombo_SelectedIndexChanged"> 
        
                                        <Items> 
        
                                            <telerik:RadComboBoxItem Text="All" /> 
        
                                        </Items>                         
        
                                    </telerik:RadComboBox>            
        
                                </FilterTemplate>                     
        
                            </telerik:GridBoundColumn>

    
                Protected Sub FilterCombo_SelectedIndexChanged(ByVal o As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs) 
        
                    Dim filterExpression As String 
        
                    filterExpression = "([Application] = '" + e.Value + "')" 
        
                    RadGrid1.MasterTableView.FilterExpression = filterExpression 
        
                    RadGrid1.MasterTableView.Rebind() 
        
                End Sub

[Solved] Request for an EmptyTemplate

Can we get the ability to render out a definable empty template if there's no data in the tree?

...or if not doable for Q1 2011, can you just put in the ability for it to render out an Empty Message?

(I know I can do it myself, but I have a bunch of treelists I plan to make so I dont want to have to keep hiding\showing based on dataset results)

Thanks,
Steve

Detect when RadWindow is closed by the user.

I have a .NET asp page that opens a RadWindow. Is there a way to know when the RadWindow is closed by the user? I have a function that I need to execute when the RadWindow is closed. I have tried setting DestroyOnClose to true and calling my function through the OnClientClose event, but setting DestroyOnClose to true causes a popup error on my page. The error says "Exception while executing client event OnClientClose Error:'this._iframe' is null or not an object." I have no idea what is causing that error. Is there a way to detect when the user closes the RadWindow without using DestroyOnClose and OnClientClose? Do you know what is causing my error when I do use those things?

I appreciate any help. Thanks,
Erika

GridDateTimeColumn with DateTimePicker is grayed out and doesn't work

Hi,

I am having a problem that I can't figure out. I am trying to use the RadGrid to manage a list, part of which is a LastUpdated for each item. It is stored in a database as a DateTime and I am using a LINQ to SQL datasource object. Everything works great in the grid except the date time picker. I am using the following code for my Date Time column:

    
            <telerik:GridDateTimeColumn DataField="LastUpdated" HeaderText="LastUpdated"  
        
                                        SortExpression="LastUpdated" UniqueName="LastUpdated"  
        
                                        DataType="System.DateTime" PickerType="DateTimePicker">
        
            </telerik:GridDateTimeColumn>

The date and time picker icons show up but they are grayed out and I can't do anything with them. I have searched and searched and no one else seems to have had this problem and I have made sure my code is using the exact same syntax as others who have gotten theirs working. What am I doing wrong. Did I forget something important? I am using the ASPNET AJAX Q2 2008. Thanks in advance.
