RowDetail Question

[Lee]

I'm using a RadGridView with a custom RowDetail template that contains buttons for performing editing functions.  I want to be able to call a function that is located within the XAML that contains the parent grid to let it know that some editing has been done and completed.

Is there a way to call functions or modify properties in the parent grid from within the RowDetail template button click handlers?

Hi Lee Weisenberger,

From within your row details control, you can find the parent grid with the ParentOfType<RadGridView>() extension method and do anything to it. The extension method is in the Telerik.Windows.Controls namespace.

Let me know if there are problems.

I'm sorry, I misspoke when I said I wanted to access a function within the XAML.  I meant to say that I want to access a function within the codebehind for the XAML.

I have a public helper function in the MainPage.xaml.cs that is used to make some updates to private variables and then post those changes to a database.  Is there a way to call the public helper function from the RowDetails template codebehind?

Thanks.

Hi Lee Weisenberger,

The "function within the codebehind for the XAML" is a member of the user control that RadGridView is inside. So find this top-level user control with the ParentOfType<T> method. This is the control that owns the methods that you are talking about. Then execute them:

var mainWindow = this.ParentOfType<Window1>();
mainWindow.DoSomething();

I hope this helps.

Thanks Ross!  That's what I was looking for.

I did have to make one change to code to get it to work from within the codebehind of the RowDetail template.

In my case, I needed use the following code:

var parentGrid = this.ParentOfType<RadGridView>(); // Parent grid for the RowDetail
var mainWindow = parentGrid.ParentOfType<Window1>(); // this.ParentOfType<Window1>() returns null, use parentGrid instead of "this" keyword
mainWindow.DoSomething();

Thanks again.
