Hi,

We've had issues with horizontal scrolling in our RadGridViews with the Q1 2011 version of the WPF package for .NET 3.5 (both the first one and SP 1).

In our grids that reside inside RadExpanders (if that matters) we have several columns which in lower resolutions requires scrolling horizontally. We bind them as GridViewDataColumns. In some we have DataTemplates, but in most we just do a normal bind using the DataMemberBinding.

Until you start scrolling everything looks fine like it did in Q3 2010 and earlier versions, but when scrolling horizontally by dragging the scrollbar with the mouse especially the smaller columns tend to grow and be very wide instead of keeping the preferred width according to the content of the columns.

So now for the second time we have to revert to Q3 2010 until this gets fixed.

Has something changed which require us to add something to the XAML to make them keep the preferred width or is this a bug that will be fixed in future versions?

Hi,

I have set up a rowstyle for my radtreelistview,
however, the rows without any children are still displayed without the expand arrow infront of them

the reason for this is because I have implemented the loadondemand or lazy loading function using MVVM in the control
in order to make all the rows expandable, i have put a dummy child in each row's view model object
however, this throws me object not initialised error when I tried to filter the rows

the code below describe how i set up the rowstyle



please can you advise what was wrong? note I don't want to set IsExpandable as shown in the treelistview loadondemand demon as I'm using MVVM and want to keep the code behind clean

btw, I'm using radcontrol q1 2011

Cheers

Trying to install the latest WPF VSExtensions (2011.1.422.0) shows the following error in the log:

Since we can't change the install directory there is no way to install it, however the 419 and previous versions did work.

Hello,

I use a treeview with IsTristatemode="true", and binding CheckState property, all work's fine. For 90% of my nodes.

I have some particular nodes that are represented as hierarchical but they are not. In other word "Parts" need to behave "hierarchically", but Variable_other not.

I'd like to obtain these configurations :

[-] Part1
| -- [ ] Variable1
| -- [x] Variable2_other
       |-- [ ] Variable3
| -- [ ] Variable4

[-] Part1
| -- [ ] Variable1
| -- [ ] Variable2_other
       |-- [x] Variable3
| -- [ ] Variable4

I've tried to set IsTristatemode to false, but because of hierarchy, if I check "Variable3", "Variable2_other" is automatically checked and tristate indeterminate is not shown for Part (whereas i set in code the null value for checkstate).

I want to make the text in certain rows of my grid bold, based on a certain property of my object.  How can I create a style that has a property that I can bind to so that I can achieve this result?  I don't want to change the look at all of the GridViewCell's, just make the text inside of them bold or not bold.

EDIT:   It got it to work by using a DataTrigger.

Hi,

Another databinding question for PanelBar... I have ViewModel with two properties Header (string) and View (UserControl)

I want to bind "Header" property to the Header of RadPanelBarItem, and...
"View" property on my VM to the "content" area of the RadPanelBarItem.

For each ViewModel, there is only ONE Header and ONE View property.

I see from examples something like

<RadPanelBarItem>
  <RadPanelBarItem.Header>
      HEADER TEXT GOES HERE
  </RadPanelBarItem.Header>
 
   CONTENT GOES HERE
</RadPanelBarItem>

But I can not get this working with databindings... there are HierarchicalDataTemplate examples, but that does not compute for me, mostly because HierarchicalDataTemplate ItemsSource="{Binding View}", since View in my case is a singel property, not collection; and I am not sure if HierarchicalDataTemplate would work for a (singel value) property as a source.

This is what I got on my own...

<telerik:RadPanelBar ItemsSource="{Binding ...}">
   <telerik:RadPanelBar.ItemTemplate>
    <HierarchicalDataTemplate ItemsSource="{Binding View}">
     <TextBlock Text="{Binding Header}" />
     <HierarchicalDataTemplate.ItemTemplate>
      <DataTemplate>
       <ContentControl Content="{Binding View}" />
      </DataTemplate>
     </HierarchicalDataTemplate.ItemTemplate>
    </HierarchicalDataTemplate>
   </telerik:RadPanelBar.ItemTemplate>
  </telerik:RadPanelBar>

When trying to use IsVirtualizing we are running into an issue with checkboxes not in the initial view are set incorrectly on data load. We are not binding to IsChecked property but are binding to the CheckState property.

The following is used to define the RadTreeViewItems:


The RadTreeView includes the virtualization settings:


Does it look like the xaml is wrong?  If not, is there a work-around or a fix for this?

Without the virtualization, the RadTreeView is unacceptably slow on loading a list of just 7500 root level items.

Thanks,

T.
