This sticky thread lists known issues and breaking changes introduced in the UI for ASP.NET AJAX releases.


Q3 2011 (Version number: 2011.3.1115)

Problem: When adding items to OData enabled controls (RadMenu, RadTreeView, RadListBox, RadComboBox) through design time erroneous markup is applied to the control:

<telerik:RadListBox runat="server" ID="RadListBox1">
        <Items>
        </Items>
        <WebServiceSettings>
            <ODataSettings InitialContainerName="">
            </ODataSettings>
        </WebServiceSettings>
    </telerik:RadListBox>

Please note the added ODataSettings section. It will cause JavaScript errors on the page.

Solution: Remove the ODataSetting section and the issue will vanish. The problem is also fixed in the Q3 SP1 release, version number 2011.3.1305

Have a Fileexplorer getting the results from an FTP connection.  What I would like to do is set the selected/highlighted item from the value that will be returned in a SQL Dataset.  

For example if FileExplorer currently has FileA, FileB, FileC, FileD listed and the database says for this record use FileB, well FileB is selected.

Also how do I add the value someone upload's so it can go into the database?


            <telerik:RadFileExplorer RenderMode="Lightweight" runat="server" ID="FileExplorer1" Width="520px" Height="200px" EnableCopy="true" ExplorerMode="FileTree">
                
            </telerik:RadFileExplorer>

 


            Dim paths As String() = New String() {"/"}
            FileExplorer1.Configuration.ViewPaths = paths

            Dim deletePaths As String() = New String() {"/", "/"}
            FileExplorer1.Configuration.DeletePaths = deletePaths

            Dim uploadPaths As String() = New String() {"/", "/"}
            FileExplorer1.Configuration.UploadPaths = uploadPaths

            'The "ROOT/CanDelAndUpload/" folder Is configured with full permissions
            FileExplorer1.Configuration.ContentProviderTypeName = GetType(FtpContentProvider).AssemblyQualifiedName

When apply pre-defined css class (from class dropdown) to <p> in editor it wraps the paragraph text with  <span> and applies class to <span>

E.g. on your demo page Telerik Web UI Editor Overview Demo | Telerik UI for ASP.NET AJAX after apply .red-text to the first paragraph it resulted in 

<p><span class="redText"><strong>Barcelona </strong>is an excellent place to discover world-class arts and culture. The sights in Barcelona are second to none. Don&rsquo;t miss the architectural wonder, <a href="http://demos.telerik.com/aspnet-ajax/imagegallery/DestinationDetails?Id=1"><em>Casa Mila</em></a> - otherwise known as La Pedrera. You&rsquo;ll want to see another one of Antoni Gaudi&rsquo;s architectural masterpieces, <a href="http://demos.telerik.com/aspnet-ajax/imagegallery/DestinationDetails?Id=1"><em>Casa Batllo</em></a>, which is located at the center of Barcelona.</span>  </p>

How to apply that class to <p> using toolbar and not switching to html mode?

I have this telerik tree view control

 <telerik:RadTreeView RenderMode="Lightweight" ID="RadTreeView2" runat="server"  Width="300px" Height="350px"
EnableDragAndDrop="True" OnNodeDrop="RadTreeView1_HandleDrop" OnClientNodeDropping="onNodeDropping" OnClientNodeDragging="onNodeDragging" EnableDragAndDropBetweenNodes="true">
                <DataBindings>
                    <telerik:RadTreeNodeBinding Expanded="True"></telerik:RadTreeNodeBinding>
                </DataBindings>
            </telerik:RadTreeView>

I need to call the server side event after drop so I have added OnNodeDrop="RadTreeView1_HandleDrop"and on the cs file I have this event.

        protected void RadTreeView1_HandleDrop(object sender, RadTreeNodeDragDropEventArgs e)
        {
            RadTreeNode sourceNode = e.SourceDragNode;
            RadTreeNode destNode = e.DestDragNode;
            RadTreeViewDropPosition dropPosition = e.DropPosition;
}

The Event is not hitting after the drop is there anything I am missing.

Something like what I have done with DropDownLists for an eternity:

if (RadMultiSelect1.Items.FindChildByValue("value") != null)
{
            RadMultiSelect1.Items.FindChildByValue("value").Selected = true;
}

Just looking to auto add the logged in user as already selected on page_load.

The above doesn't seem to work.

And as usual, I did dig through the documentation and DuckDuckGo it.

Is there a way to completely disable collapsing of the RadDropDownTree control?

I want to be able to collapse and expand all the nodes, I just don't want users to be able to completely collapse the control.

In other words, I want to use it like RadTreeView but with the benefit of RadDropDownTree filtering.

Thanks!

I've been trying to resolve an issue with my RadCalendar/Datepicker with Telerik, maybe with bootstrap messing up things.

After upgrading to bootstrap 5 the calendar displays 2 extra caption spaces below the title and below the calendar. How can I remove these caption spaces? I have something simple like this in a row.

<div class='col2' <telerik:raddatepicker id="1234" mindate:"5/5/5555" calendar-showheaders="false" calendar-tltleformat="mmm yyyy" skin="telirek"

</telerick:raddatepicker>

</div>

  treeView.DataTextField = "Name";
            treeView.DataFieldID = "ID";
            treeView.DataFieldParentID = "ParentID";
            treeView.DataSource = links;
            treeView.DataBind();

 

I am binding the treeview like this.

I want to get the ID of the node that is selected not Text How do I get that throught javascript

 var destinationNode = args.get_destNode();
   var parentnode=args.get_destNode().get_parent();
   var  parentnodetext=parentnode.get_text();

here I am getting the Text but I want the Id linked to it

I want to have nodes in multi columns.

It seems to me that there is no such settings.  So I use the Content Template.  However, I found that the content template width cannot be set.

How can I set the content template width in code behind? and in aspx?

BTW, it is great if the nodes can be set in multi columns.  It will be nice if it is included in next release.

Thanks.

Alfred
