Has anyone found a way to force the minimum/initial size on tiles when you load them from a dataset? Following the online examples I set up the item template and content template, but it doesn't seem to matter what I set the minimum height and width to, the tiles resize so they all fit in the allocated window size, which causes an issue when I try to put 50 tiles in a 400 x 400 control. I tried wrapping a scroll viewer around it and letting it grow in that, but no luck.

Any thoughts or insight would be greatly appreciated.

Thanks!
Jan

Hi,

When I do the following actions:
1. Add a new row 
2. Start to edit a cell
3. Start to tab to the next cell
then I get the following error message:

Hello,
    I set the IsReadonly property of the grid to true. When I than try to set a column to writeable (gridname.Columns[0].IsReadOnly = false) it stays protected.
To get around this I set the grid's IsReadOnly propery to false and than protect certain columns by executing 
gridname.Columns[<Position of column to protect>].IsReadOnly = true

It would make more sense to allow the programmer to override the protection of the entire grid.

Is it possible today in the GridView to provide a menu in the column header that will turn on and off summary functions for columns? I can provide a way for my users to do this, but if there is built in support I would like to use it.

Thanks,
Mike

We're using the radtreeview and on the Selected event we fire off some asyncronous functionality that changes the underlying tree itemsource. The problem we're having is we're getting a null ref exception at the location below (see stack trace at the bottom).  We've tried previewSelected and get the same result there.  Our current workarond (not ideal) is to do our processing on MouseUp.  It appears that as we've removed the selected item the tree code isn't checking whether this is null.

I can’t get this to work. I can bind items to a listbox in the same way without problem…

 

 

 

<telerik:RadDocking DataContext="{Binding Source={StaticResource CustomerViewModel}}">

 

 

 

 

    <telerik:RadSplitContainer ItemsSource="{Binding Path=Customers}">

 

 

 

 

        <telerik:RadSplitContainer.ItemTemplate>

 

 

 

 

            <DataTemplate>

 

 

 

 

                <telerik:RadPaneGroup >

 

 

 

 

                    <telerik:RadPane Header="{Binding Path=CustomerName}">

 

 

 

 

                    </telerik:RadPane>

 

 

 

 

                </telerik:RadPaneGroup>

 

 

 

 

            </DataTemplate>

 

 

 

 

        </telerik:RadSplitContainer.ItemTemplate>

 

 

 

 

    </telerik:RadSplitContainer>

 

 

 

 

</telerik:RadDocking>

Hi,

I was told by Evan Hutnick that you were working on a TreeListView for WPF and that it should be made available in a Beta Release around the Q3 release. I cannot find it anywhere so I was wondering if I've missed something or what the status is on that control?

We have a project where such a control is very important and I would consider replacing the one we have with yours if it was good.

Hello,
I am having a problem with a combo box column in my GridView using WPF. 
The gridview rows and combo box are bound to two separate collections, linked by a key of type integer.
When the gridview loads both the rows and combobox column are filled with the correct data, but when I try to update the value in the combobox (select a different value) it does not work. 
I can open the combobox list and see the different values available, but when I try to select a value in the combo box it reverts back to the original value.

My gridview is setup with the following xaml:
<telerik:RadGridView Name="rgvAppConfig" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ScrollMode="RealTime" IsTabStop="False" 
                                             AutoGenerateColumns="False" ColumnsWidthMode="Auto" ItemsSource="{Binding}"                                                
                                            > 
                        <telerik:RadGridView.Columns> 
                                <telerik:GridViewDataColumn UniqueName="Id" IsVisible="False" /> 
                                <telerik:GridViewDataColumn UniqueName="MessageType" Header="Message Type"/> 
                                <telerik:GridViewDataColumn UniqueName="Description" Header="Description"/> 
                                <telerik:GridViewDataColumn UniqueName="SaveLocation" Header="Save Location"/> 
                                <telerik:GridViewDataColumn UniqueName="FieldDelimiter" Header="Field Delimiter"/> 
                                <telerik:GridViewDataColumn UniqueName="ComponentDelimiter" Header="Component Delimiter"/> 
                                <telerik:GridViewDataColumn UniqueName="SubComponentDelimiter" Header="SubComponent Delimiter"/> 
                            <telerik:GridViewComboBoxColumn UniqueName="ImageType" Header="Image Type" DisplayMemberPath="Name" DataMemberBinding="{Binding SaveImageType}" SelectedValueMemberPath="Id"  ItemsSource="{Binding}" /> 
                            <telerik:GridViewDataColumn UniqueName="Enabled" HeaderText="Enabled"/> 
                            </telerik:RadGridView.Columns> 
                        </telerik:RadGridView> 

</telerik:RadTabItem> 

Which is loaded with the following:
IList<Common.DAL.AppConfig> appConfig = 
                        (from x in Common.DAL.AppConfig.All() 
                         select x).ToList(); 
IList<Common.DAL.ComBinaryType> comBinaryType = 
                        (from x in Common.DAL.ComBinaryType.All() 
                         select x).ToList(); 
rgvAppConfig.Columns["ImageType"].DataContext = comBinaryType; 
rgvAppConfig.DataContext = appConfig; 

How can I resolve this so when a value it selected from the combo box it retains the value to was selected and updates the collection?

Thanks,
Matt

I have a Bar chart defined where the user can toggle between 2-D and 3-D.  XCategory labels work great in 2-D, but in 3-D pointmark values are displayed instead of labels.  Is there a way to show pointmark labels instead of values in 3-D?

Hello,
    I've loaded a datatable cell with some text but the associated grid cell is not showing anything unless I click on the cell. When I click on the cell 3-4 lines of text appear.
I have to set the grid to read-only so now nothing will show up because the cell is read-only.
Any help would be appreciated.
Thanks
