I would like to display "Yes" or "No" for a Boolean in RadGridView instead of a checkbox. I would like to implement this changes in xaml. Columns are generating dynamically. This is how it's created now:

 <telerik:RadGridView x:Name="Data" Grid.Row="3" Margin="5" AutoGenerateColumns="False" CanUserSortColumns="True" IsFilteringAllowed="True"
                                 grid:RadGridViewColumnsBinding.ColumnsCollection="{Binding Path=Columns}"
                                 IsReadOnly="False" CanUserResizeColumns="True"/>

 

I am new in Silverlight coding. Will really appreciate if someone can help.

Hello,

I'm attaching a sample project based on your requirements. All I've done is added a BooleanToYesNo converter and set it as the Converter for the respective binding. Please have a look and let me know whether this works for you.

Thank you for the attached project. This was very helpful. On a different note, currently in the checkbox, when none of data there in backend it shows a blue sign in the checkbox. (for 1 it shows as checked, for 0 shows as unchecked/blank). Any idea how this blue sign could be setup or how to get rid of the blue signfrom the Checkbox?

Hi,

I am not sure that I can understand your question. May I ask you to share more details? An image would be helpful.

In the image where it shows blank in checkbox for 'false' and checked for 'true'. Where no true false has been passed(the value is null), it shows this blue/purple sign in the checkbox. Want to get rid of it. Couldn't figure how it's implemented there.

Hello,

The blue sign you're referring to is the undetermined state of the Tri-State CheckBox.
One way to get rid of it, if applicable, is to make the respective boolean property of your business object non-nullable so that a default value of false is set.

Your other option is to style the CheckBoxColumn, and more specifically - the IndeterminatePath of its Indeterminate visual state, to your liking.

I hope you find these suggestions helpful.
