I have a combobox that is populated by a sqldatasource. I would like for the combobox to show..."Please select an item" or just have it blank, when the page loads. How do i accomplish this?

I am working on cleaning up an application and am running into a problem where there is an instance of a the schedular that displays as if its absolutely positioned in IE7, later browsers display it correctly. I don't think its a stylesheet issue as it uses the telerik skin. I also had this problem with the radgrid on the same page but solved it by removing some attributes that were off.

Can i change the "SearchPatterns" in the Fileexplorer window from another aspx-site. I use the File Selector Dialog. I would like use only "SearchPatterns"  jpg, png and gif from the one aspx-site and pdf, ppt ... from the other aspx-site. Can i transfer the right "SearchPatterns" to the Fileexplorer windows?

I have a simple RadListBox and RadFileExplorer on a page, I would like to click on an item in the listbox and change the ViewPaths, UploadPaths and DeletePaths of the RadFileExplorer based on the listbox selection.

I have configured a RadAjaxManager to update the RadFileExplorer when the Listbox selection is made.

Problem is that this new BindExplorer method available in the latest release is not accessible because it is protected.

Does anyone have any pointers?

Hi,

I am using rotator to show 8 images. Below is a sample code. First time when the page loads, it shows all images proper in the rotator.
But when I press the next or previous buttons, it cuts the image at the start or end.

This issue is also with Telerik's demo. I have attached it's image. Is there any specific property or any logic to show all images proper every time user clicks the next or previous buttons ?

Thanks for your reply

Hello,

We are using Telerik Controls Version 2009.2.826.20 in our application and we are experiencing difficulties with RAD TreeView Node in the Context Menu Item.

Below is the set of RAD Controls we are using in the Application:

1. Toolbar control. (This renders the functioanlity very fine)
2. RAD Splitter Control.
3. Left Pane we got RAD TreeView Control. (Implement Load on Demand using Page Behind Method)
4. Right Pane we got sub Panels using DIV Controls. We are show/hide the Div's depending on the items selected in the Context Menu of the Tree View Control.

When we run the application, we are able to expand or collapse the Nodes. When the User right click a Node and select an item from the Context Menu, the event for the Context menu throws Object Reference Error. Sometimes it works and some times it doesnt work.

Why is the behavior as such? Can you help us to resolve this issue?

Below is the Code we have in our application for the Context Menu Item Event:
(We are accessing the node using e.Node and if the e.Node is present it works. In so many cases e.Node is becoming NULL and this is giving us the error Object Reference not set to an instance of an Object)
(The application works if we use the button from the ToolBar. Because in ToolBar event, we are accessing the Node using SelectedNode property and that works)

    Protected Sub RdTViewPerspective_ContextMenuItemClick(ByVal sender As System.Object, ByVal e As Telerik.Web.UI.RadTreeViewContextMenuEventArgs) Handles RdTViewPerspective.ContextMenuItemClick
        Try
            Select Case e.MenuItem.Value.ToUpper()
                Case "SAP_INFO"
                    HideAllPanels()
                    DisplayGeneralInformation(e.Node)
                    DisplaySAPInfoPanel(e.Node)
                    ReSetToolBarButtons(e.Node)
                Case Else
                    'Nothing to do.
            End Select
        Catch ex As Exception
            log.Info(ex.Message.ToString())
            Response.Redirect("CustomError.aspx?Msg=" + Server.UrlEncode(ex.Message.ToString()) + "&ErrorSource=" + Server.UrlEncode(ex.Source.Replace(Environment.NewLine, "-----><BR>").ToString()) + "&ErrorStack=" + Server.UrlEncode(ex.StackTrace.ToString()), False)
        End Try
    End Sub

Thanks

I have a combo box in my grid, when I edit the underlying data I want the current data item to be selected in the combo box


in my codebehind I have this



this line
combo.FindItemByValue(DataBinder.Eval(e.Item.DataItem, "CastMemberName").ToString()).Selected = true;

should select the current name in the combo, but it doesnt.  The first item in the the combo is always set.
Ive used this method many, many times before and its always worked, yet in this case it wont !

Ive checked the value in CastMemberName and its a valid name that is in  the data bound to the combo.
Can anyone see what the problem is ?
