I am trying to get the GridView to work in a rather complex scenario that involves numerous dynamic columns all with their own editing and display criteria. I have come up with a solution that involves storing a metadata object on the column and then I bind to the properties on the metadata object in the Tag property.

This approach has been working fine or non-dynamic columns but I am unable to successfully determine the property to bind to in the cell template as the property name is decided at runtime, hence why I store it in the DynamicPropertyName property in the metadata.

I tried using a MultiValueConverter which works fine for the ConvertTo, but I am unable to provide the correct values in the ConvertBack.

This is my current cell template with the binding issue highlighted - if there is a way to also bind the Column.Tag.DynamicPropertyName property on the ParentRow. object which is a DynamicObject, then this approach would work in its current form.

                                       ShowColumnSortIndexes="True"
                                       ItemsSource="{Binding SizeDetailsList}"
                                         SelectionMode="Single"
                                       RowIndicatorVisibility="Visible"
                                       VerticalAlignment="Stretch"
                                         IsReadOnly="False" AddingNewDataItem="radGridSizeDetails_AddingNewDataItem">

Let me know if I miss anything.

RadDataBar: How to make the text fit at the end

I need to get the fit of the maximum on the length of the control, either that or move the label below the line.

For the first option, I was thinking of reducing the value,and then customizing the labeltext that shows up. Only issue is, not sure how to modify the textblock that shows that value.

Second option, kind of related to the first one, how can I use a datatemplate to have a template where the label is below the line?

Please refer to image attached.

Thanks!

[Solved] RadLegend

Hello,

I am struggling to include a <telerik:RadLegend> tag in my code. I have been using your documentation at http://www.telerik.com/help/wpf/radlegend-overview.html as a reference but always get an error message.

I have included a reference to Telerik.Windows.Controls.dll as well as including xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" as a namespace declaration in my XAML, but whenever I try to use a <telerik:RadLegend> tag I get an error stating "The type 'telerik:RadLegend' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been build."

Any help on this would be appreciated.

Andrew.

RadTabControl RadTabItems in a RadDataForm

Hi,

In the application (WPF - MVVM) I am working on, there is a RadDataForm inside which I have implemented a RadTabControl with 2-3 RadTabItems. Also there are "ReadOnlyTemplate" and "EditTemplate" for the RadDataForm.

There is an issue with particular operations. I will try my best to explain the situation. But let me know if further details are needed.

In "ReadOnlyTemplate" mode of the DataForm, I have a few fields that are DataFormDataFields. But these values are DataFormComboBoxFields when the RadDataForm is in "EditTemplate" mode. So when I Edit the form and change tabs and then save/cancel the changes, then when the RadDataForm goes back to the "ReadOnlyTemplate" mode, but the DataFormDataFields of these fields that were DataFormComboBoxFields in "EditTemplate" mode show blank values. but if I edit and not change the tabs in edit mode and then save/cancel changes, then everything is perfect. The bug is only when I change tabs in edit mode and then save/cancel changes .

It would be helpful if anyone can help me figure if its a bug or is it something I am doing wrong here.

Remove Arrow From Row Indicator

Is there way to remove the arrow from the rowindicator column? I am using the row indicator as more of a multi select piece and don't really want to show that arrow.

The other question I have is how do you have that arrow not show up until something is selected? I have tried to set selecteditem=null, but it still shows up.
