When items with different values have the same text, a postback is not triggered when selecting another item with the same text as the current selection. The workaround is to place the following script under the ScriptManager:

Telerik.Web.UI.RadMultiColumnComboBox.prototype._shouldPostbackOnChange = function myfunction() {
    return true;
}

Reproduction code:

<telerik:RadMultiColumnComboBox ID="RadMultiColumnComboBox1" DataKeyNames="Additional" runat="server" DropDownWidth="Auto" AutoPostBack="true" >
    <ClientEvents OnSelect="OnSelect" />
    <ColumnsCollection>
        <%--<telerik:MultiColumnComboBoxColumn Field="ID"></telerik:MultiColumnComboBoxColumn>--%>
        <telerik:MultiColumnComboBoxColumn Field="Name"></telerik:MultiColumnComboBoxColumn>
        <telerik:MultiColumnComboBoxColumn Field="Additional"></telerik:MultiColumnComboBoxColumn>
    </ColumnsCollection>
</telerik:RadMultiColumnComboBox>
<script>
    function OnSelect(sender, args) {
        //alert("selection changed");
    }
    // Workaround
    Telerik.Web.UI.RadMultiColumnComboBox.prototype._shouldPostbackOnChange = function myfunction() {
        return true;
    }
</script>

public class MyClass
{
    public int ID { get; set; }
    public string Name { get; set; }
    public string Additional { get; set; }
}
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        RadMultiColumnComboBox1.DataSource = Enumerable.Range(1, 20).Select(x => new MyClass()
        {
            ID = x,
            Name = "Same Item text" ,
            Additional = "DataKey#" + x
        });
        RadMultiColumnComboBox1.DataTextField = "Name";
        RadMultiColumnComboBox1.DataValueField = "ID";
        RadMultiColumnComboBox1.DataBind();
    }

Replicated when the ClickToOpen is enabled: 

protected void Page_Load(object sender, EventArgs e) { RadGrid1.HeaderContextMenu.ClickToOpen = true; }

WORKAROUND: Loading the following script under the script manager

<script>

    Telerik.Web.UI.GridColumn.prototype._onContextMenuItemClicking = function (sender, args) {
        original.call(this, sender, args);
                
        var item = args.get_item();
        var itemValue = item.get_value();
        if (itemValue == "FilterList" || itemValue == "FilterMenuContainer" ||
            itemValue == "AggregatesContainer" || itemValue == "FilterMenuParent" || itemValue == "ColumnsContainer" ||
            (Telerik.Web.UI.RadMenuItem.isInstanceOfType(item.get_parent()) && item.get_parent().get_value() == "ColumnsContainer")) {
            if (sender.get_clickToOpen()) {
                args.get_item().open();
            }
        }

If you setup multiple RadEditor controls on a single page with RenderMode set to Lightweight then when you change the foreground or background colour on one control, the other controls update their toolbar at the same time.

Sample Page code
    <h1>Editor 1</h1>
    <telerik:RadEditor ID="editor1" runat="server" RenderMode="Lightweight"></telerik:RadEditor>

    <h1>Editor 2</h1>
    <telerik:RadEditor ID="editor2" runat="server" RenderMode="Lightweight"></telerik:RadEditor>

Endless Loading screen is shown over RadPane when the set_showContentDuringLoad(false) method before changing the contentUrl of a RadPane (which is already showing another external page).
 

Workaround: Set the ShowContentDuringLoad="false" property of the RadPane in the markup initially

 

Code to reproduce the bug:

        <script>
            function loadNewPage() {
                var contentPane = $find("RadPane2");
                contentPane.set_showContentDuringLoad(false);
                contentPane.set_contentUrl("newContentPage.aspx");
            }
        </script>

            <telerik:RadPane ID="RadPanel1" runat="server" Height="30px">
                <asp:Button Font-Italic="true" runat="server" Text="Load New Page" OnClientClick="loadNewPage(); return false;" />

If paging is disabled and the PageSize is set to less than the number of records bound to RadGrid, client item templates are not all rendered correctly.

Example:

If PageSize is 10, and records bound to Grid are 15, then the first 10 records will have templates rendered correctly, while the rest of 5 records will not.

Uncaught TypeError: Cannot read property 'dispose' of undefined

Workaround:
Enable the external dialogs of the Editor/ImageEditor and modify dispose() function of the Print.ascx dialog:

 

Print.ascx

				dispose: function ()
				{
					this._attachHandlers(false);

					this._printBtn.dispose();
					this._cancelBtn.dispose();

					$IE.Print.callBaseMethod(this, "dispose");

We recently added row group functionality to our grids and we and our users are very happy with this.

 Only thing that bothers us is the drop functionality on the grouppanel. We an issues to make the drop functionality of the grouppanel much more intuitive. Especially when the RadGrid is already grouped on multiple columns.

The drop marker indicated the new column to group will be added in front, but the column is added to the end of the grouped columns.

Forum reference:

This is reproducible in the demo on your site. See also the added video.

.hasChanges() results in records flagged for Delete to not actually get deleted when .saveChanges() executes.

I found the same behaviour on a LiveDemo example that checks .hasChanges(): Grid - Binding to Telerik ClientDataSource

Steps to reproduce:

  • Make any change to the first record, such as modifying the Contact Name.
  • On the second record, Click the "x" under the DELETE column to mark it for delete.
  • Click any column heading to sort.  (This calls a UserAction event handler that calls .hasChanges())
  • Choose to Cancel at the popup prompt.
  • Click "Save changes".
  • Monitor the browser console, you will find that webservice UpdateCustomers is called,  but DeleteCustomers is not.
