How to find the parent row of a nested grid on a drag and drop

What's the easiest way to find the parent row of a nested grid that you just dragged and dropped to (ie destination).

Here's what I have and it works fine but I know there's a simpler way because I remember seeing one like a year or so ago and just can't remember.

    
            DirectCast(e.DestDataItem.Parent.Parent.Parent.Parent.Parent.Parent, Telerik.Web.UI.GridNestedViewItem).ParentItem

This does give me the parent row of a nested grid when I dragged and drop on the nested grid, but like I mentionned there's a simpler way and I just can't remember it.

Thanks

"this" in Telerik client events?

I am using a telerik:RadTabStrip in a .ascx user control. I want to call a function in a javascript object when the client tab is changed.

In the code-behind, I'm doing:

    
            radTabStrip.OnClientTabSelected = "foo.clientTabSelected";

Where "foo" is a javascript object that contains some data, and a number of functions - one of which is clientTabSelected.

    
            function Foo() 
        
            { 
        
                this.selectedTab = loadCookie('foo.cookie'); 
        
            } 
        
            Foo.prototype = { 
        
                clientTabSelected: function(sender, eventArgs) 
        
                {

                    debugger;

                    var tab = eventArgs.get_tab(); 
        
                    if (tab) 
        
                        this.selectedTab = tab.get_index(); 
        
                    storeCookie('foo.cookie', this.selectedTab); 
        
                }, 
        
                //... 
        
            }

The object "foo", of course, is initialized prior to the user clicking a tab.

The problem is that when the user clicks on the tab, the "clientSelected" function is called, but not on the object "foo". In other words, when I trace through the execution, the correct function is being called, but within the function, "this" is not set to the "foo" object.

Any ideas as to how I can connect a Telerik event to a function in a specific object?

RowClick & RowDoubleClick

Does anyone know if we are able to have both Rowclick AND RowDblClick fire together? If I have them both configured, only Rowclick seems to fire.

Any ideas?

Thanks!

Setting Selected Values from SqlDataSource

I have a SqlDataSource (Regions_SqlDataSource) populating the RadListBox.
I have another SqlDataSource (SelectedRegions_SqlDataSource) that gets the selected values from the database.

I cannot seem to figure out how to set the selected values of the RadListBox based on the SelectedRegions_SqlDataSource.
I can get it to select the first returned value of the SelectedRegions_SqlDataSource, but it does not select all of the returned values.

Here is my code.

    
            Dim regionsSql As DataView = DirectCast(SelectedRegions_SqlDataSource.Select(DataSourceSelectArguments.Empty), DataView)  
        
                    For Each regionsviewSql As DataRowView In regionsSql  
        
                        If Not Page.IsPostBack And regionsviewSql("PreferenceValue").ToString <> "" Then 
        
                            Regions_RadListBox.SelectedValue = regionsviewSql("PreferenceValue")  
        
                        End If 
        
                    Next

And here is the listbox and data sources.

    
            <telerik:RadListBox ID="Regions_RadListBox" runat="server" Width="200px"   
        
                  SelectionMode="Multiple" Rows="3" TextMode="MultiLine" DataSortField="Region"   
        
                  DataSourceID="Regions_SqlDataSource1" DataTextField="Region"   
        
                  DataValueField="RegionID" Height="60px">  
        
            </telerik:RadListBox>

    
            <asp:SqlDataSource ID="Regions_SqlDataSource1" runat="server"   
        
                ConnectionString="<%$ ConnectionStrings:SiteSqlServer %>"   
        
                SelectCommand="SELECT [RegionID], [Region] FROM [NC_CT_Regions]"></asp:SqlDataSource>  
        
            <asp:SqlDataSource ID="SelectedRegions_SqlDataSource" runat="server"   
        
                ConnectionString="<%$ ConnectionStrings:SiteSqlServer %>"   
        
                SelectCommand="SELECT PreferenceValue FROM NC_EmployeePreference WHERE PreferenceTypeID = '4' AND EmpID = @EmpID">  
        
                <SelectParameters>  
        
                    <asp:QueryStringParameter Name="EmpID" QueryStringField="EmpID" />  
        
                </SelectParameters>  
        
            </asp:SqlDataSource>

RadEditor as Textbox UI for Outlook Skin

Hi,
I have upgraded to the 2008.2.1001.35 release of RadTools.
I had implemented your solution for displaying the RadEditor with a single pixel border (to look like a simple imput box) using the Default skin.
The solution does not work for the Outlook skin.

Can you provide a modification to that solution which works with the Outlook skin?

This solution you provided was taken from documentation section your Web site.

Thanks, Andy

RadGrid load all data before paging

Hello,

currently I have ~300 rows and over 21 columns of data.(Both of those will rise over time) And I'm also implementing paging. It takes a long time to switch between pages, because RadGrid is accessing the Database each time I switch a page, is it possible to load all the data into the RadGrid, for all pages, so when I would change pages it would just show those from cache or somewhere and reduce the time taking between those page changes?

Thanks in advance and regards,
Thomas

ComboBox height

How can I reduce the height of combobox below 22 pixels as we need to use a lot on one page and it is effecting the layout of our page. I have tried changing the CSS but increasing the height works but decreasing it doesn't. I assume it is related to the images?

[Solved] Insert vs. Edit

I have a customvalidator a DataBoundColumn in a RadGrid. In the validator I need to know whether I am inserting a new item or editing an old item in the ServerValidate handler.

Is there any well to tell at that point?

Also, while in the ServerValidate handler is there a way to get the previous value of the control?

Thanks,
Steve

How can I clear Undo/Redo history on postback?

We are using an ajaxified Dropdown list and RadEdit to edit different content blobs from a database. We have found that the Undo function will load the content of the RadEdit from a previous content loaded/replaced by ajax event.

So my question is, how -- using js and/or code-behind -- can I clear the Undo history?
