Hello,

After upgrading to Q1 2011 I am getting this exception from time to time:

System.InvalidOperationException: Cannot resolve all property references in the property path 'Effect.Progress'. Verify that applicable objects support the properties.

Any ideas ?

The RadCarouselPanel control looks more like a coverflow. Can it be modified like a horizontal slideshow?

Hi!
I'm using standard Telerik filtering control.
My question is: How to set filtering in code and make that selection visible in FilterControl.

I tried to set FilterDescriptor in code. It works fine. Grid filters rows but FilterControl does not check exact checkbox.

Thanks!

 

Hi all,

We have an issue with the TreeView, this issue is that when we select the checkbox of the parent, the child checkbox is not being selected. The weird part is that this behaviour only happens the first time when the tree is not expanded yet. If the tree is expanded then the behaviour works as expected.

I debugged on the events and I see that it only comes once in the event, which normally should happen twice. Is this a bug? Or how can I solve this issue?

Here is our TreeView:

<telerik:RadTreeView x:Name="treeModules"  SelectionMode="Extended" IsLineEnabled="True"
                                                        ItemsOptionListType="CheckList" IsOptionElementsEnabled="True"
                                                        IsRootLinesEnabled="True"  VerticalAlignment="Top" Margin="10" 
                                                        IsTriStateMode="True" Selected="treeModules_Selected"
                                                                         MouseRightButtonUp="treeModules_MouseRightButtonUp" ItemContainerStyle="{StaticResource ItemContainerStyle}"
                                                                         ItemsSource="{Binding ModuleListHelper, Mode=OneWay}" Checked="treeModules_Checked" Unchecked="treeModules_Checked">

                                                        <MenuItem x:Name="ctMenuDelete" Click="ctMenuDelete_Click" Header="Delete">
                                                            <MenuItem.Icon>
                                                                <Image Source="/images/trash.gif"/>
                                                            </MenuItem.Icon>
                                                        </MenuItem>

                                                </telerik:RadTreeView.ContextMenu>
                                            </telerik:RadTreeView>
                                                <telerik:RadTreeView.ContextMenu>

                                                            <MenuItem.Icon>
                                                                <Image Source="/images/trash.gif"/>
                                                            </MenuItem.Icon>
                                                        </MenuItem>
                                                    </ContextMenu>
                                                </telerik:RadTreeView.ContextMenu>
                                            </telerik:RadTreeView>

Thank you!

I just wanted to create completely custom styled <telerik:OrientedAppointmentItemStyleSelector.HorizontalStyle> items. I've created resources via Expression Blend and all that stuff.

Then I wanted to edit the template like follows - making it bigger and putting additional controls in it.

I can put additional controls in the grid, but it is not getting bigger. The size remains small and the content is cut off. The Height="150" property seems to have no effect. What's going on here?

Let DoubleValue be a wrapper type around a Double, with an attached TypeConverter that knows how to convert from/to Double. And suppose that we have a GridViewDataColumn bound, via DataMemberBinding, to a property of this type. Pasting numeric strings to this column doesn't work, internally generating an InvalidCast exception.

To me this looks like a bug, the column is ignoring the attached type descriptor. It should be doing

Hi,
I am facing an issue while using the telerik treeview in below scenerio.
the images of the expander has to be changed and it has to be dynamically chosen between two images based on the data is binded to it.
when data is binded to the treeview, based on the boolean column, the nodes has to display different images, if this value is true it has to show one image and if it false it has to show another image.
when the node has expanded, then the image of that noted should be rotated version of the image shown earlier (before expanding).

Hi,

What do I need to configure so that when ever user clicks a child item of the hierarchical grid SelectedItem is fired?

This is what I am observing

Parent 1
Child A
Parent 2
Child B

When selecting Child A SelectedItem is fired. Selecting Child B SelectedItem is fired as well. The problem is that Child A is still selected. How can unselect Child A.

I have read in this forum that the child and parent SelectionMode are independent.  Is there a way to tie them together?  I only want ONE record shown as selected regardless of whether it is a parent or child.

if * and BOLD means "selected/highlighted", this is what I am seeing:

* Parent 1
   * Child A
   * Child B
Parent 2
   * Child C
   * Child D

What I desire is if I clicked on Child A again is for all other rows to be deselected and ONLY Child A is highlighted, no parent records selected, no other children.   I would like SelectionMode = Single across all data relations.  Is this possible?

Parent 1
   * Child A
    Child B
Parent 2
    Child C
    Child D

I would show an image but I guess you can't do attachments in the forum.

Thanks in advance!

Is there a way to Cancel in the middle of editing an item in the RadDataForm?  
When I click on the Add Button, both the Commit Button and Cancel Button are enabled, so I can cancel out of creating a new record.
When I click on the Edit Button, the Commit Button is enabled, but the Cancel Button is grayed out.  

I am binding an ObservableCollection of objects to the RadDataForm ItemsSource property which gets loaded in the WindowLoaded event handler, and reloaded after adding, editing or deleting an item in the collection.   

I would like the user to be able to cancel an editing operation where the item being edited reverts to its previous state if the user clicks the Cancel Button.  Is this possible?
