Single Column Sorting

Is it possible to just sort on one column at a time? I have alot of columns and don't want the user
clicking on a million columns to sort. It just gets to complicated. So I just need the column sorting on one
column at a time. Is this possible?

Thanks!

How to display the foreign key value in grid

I want to display the textual value of a foreign key, while binding to the id value in the orginal table in the grid and in edit have a combo box to edit.

e.g in a normal combo i would do something like:
<ComboBox Name="TypecomboBox" ItemsSource="{Binding Source={StaticResource personTypesData }}" DisplayMemberPath="Name" SelectedValuePath="PersonTypeID" SelectedValue="{Binding Path=PersonTypeID}" />

What's the equivalent to this in the grid control?

I can set the grid to edit as a combo using the comboeditor. How do i display the textual value rather than the ID?

Horizontal maximization not satisfactory

In my tile view, I have managed to maximize horizontally as shown below. The problem is that when I maximize an item, the minimized items are arranged horizontally below it.

I want this layout when an item is maximized:
_______
|             |
|______ |
|___|___|
|___|___|
|___|___|

And when all items are minimized:
_______
|___|___|
|___|___|
|___|___|

    <telerik:RadTileView Margin="0"
                      ColumnsCount="1"
                      ColumnWidth="400"
                      MinimizedItemsPosition="Bottom"
                      ContentTemplate="{StaticResource contentTemplate}"
                      IsAutoScrollingEnabled="True"
                      IsDockingEnabled="True"
                      IsVirtualizing="True"
                      ItemsSource="{Binding Images}"
                      ItemTemplate="{StaticResource headerTemplate}"
                      MinimizedColumnWidth="200"
                      MinimizedRowHeight="200"
                      PreservePositionWhenMaximized="True"
                      RowHeight="200"
                      TileStateChangeTrigger="SingleClick" />

App Key cause selection change before display context menu

When I press the App key or Shift+F10 on a selected node of my tree, the selection changes to the parent of the node and then it displays a wrong menu in the upper left-hand corner of the window.
I'm using a RadContextMenu with the RadTreeView.
Is there a fix or work-around for this behavior? Or am I doing something wrong?

Itemscontrol in column template is very slow

Hi,

For one of the columns in my gridview, I need to use an ItemsControl. That column is bound to a variable list of 'events', which are strings. For each of these events, a link/button needs to be generated in the column.

My column is defined as follows:

<telerik:GridViewDataColumn Header="Actions"

<telerik:GridViewColumn.CellTemplate

>

        <DataTemplate>

<ItemsControl ItemsSource="{Binding Path=Events}">

<ItemsControl.ItemTemplate>

<DataTemplate>

<Button cal:Message.Attach="ExecutePipEvent($dataContext)" Content="{Binding}"/>

</DataTemplate>

</ItemsControl.ItemTemplate>

<ItemsControl.ItemsPanel

<ItemsPanelTemplate>

<StackPanel Orientation="Horizontal"/>

</ItemsPanelTemplate

</ItemsControl.ItemsPanel

</ItemsControl

</DataTemplate

</telerik:GridViewColumn.CellTemplate

</telerik:GridViewDataColumn>

The problem is that this column makes the rendering of each row very slow. Without this row however, the grid is rendered fast.

Anyone experienced the same problem or knows what the problem is? That would be great!

Need sample

Hi,

we use VS2008 and telerik 2012.2.912.35 and we have a RadWindow and we're trying to use the êrsistenceFramework mechanism without any success :(

In our RadWindow, we have a RadRibbonView with RadDocking control and in the RadDocking control we have 3 panes. One pane contain a RadGridView, one pane contain a RadRichText and the last pane contain multiple TextBox.

In the application menu of the RadRibbonView, we implement an to to persist the layout of the RadWindow. Actually, when we click on the persist button, when in Loaded event we restore the layout, the application menu of the RadRibbonView appear open, the RadRichText contain the text of the moment when we persisted and it's the samething for all the TextBox.

After many hours of experimentation, we gave up :( Can you provide us a small demo on how to exclude the RadRibbonView and all the date of each controls from the persisting process.

Thank's

ContextMenu ItemsSource between Header and Footer Items

Hello,

is it possible to define an ItemsSource for a RadContextMenu only for a particular Part of the ContextMenu?
My Target is to have Header and Footer Items, which are always shown up (fixed Items) and to have Contextual Items which are filled from Item behind.
I tried it with an ItemsControl. This works so far, but if I hover one Contextual Item, the full ItemsControl is highlighted. Also the Icon is indented. Please see the attached Screenshot.

How can I remove the wrong highlighting and the Icon Indentation?

Thank you for your help!

My existing Source Code is the following (see ItemsControl):

RadContextMenu.Resources>

<DataTemplate x:Key="SubItemTemplate">

<telerik:RadMenuItem Header="{Binding DisplayName}" IsEnabled="{Binding Enabled}">

<telerik:RadMenuItem.Icon>

<Image Stretch="Fill" MinHeight="0" MinWidth="0" MaxWidth="16" MaxHeight="16" Width="Auto" Height="Auto" Source="{Binding Image}" />

</telerik:RadMenuItem.Icon>

</telerik:RadMenuItem>

</DataTemplate>

</telerik:RadContextMenu.Resources>

<telerik:RadMenuItem Header="Add" ItemsSource="{Binding Path=PossibleSubItems}" FontWeight="Bold" ItemTemplate="{StaticResource SubItemTemplate}">

<telerik:RadMenuItem.Icon>
