Custom args to WindowClosedEventArgs

[Michael Fooks]

When I use the WindowClosedEventArgs I need to be able to pass my own variable all the way through so i can use the variable on close.  Can we get an "arg" parameter or something to do this? ATM it looks like i'll have to make a bunch of member variables to hold the state.

Hello Bronwen Zande,

Can you elaborate more on what you try to achieve? What do you mean with "I need to be able to pass my own variable all the way through so i can use the variable on close"
Do you need to expose value from some control that is inside RadWindow and populate it on Closed event? If this is your case you can use Tag property to store some value in closed event and use it after that.

Let us know if that is not your case.

All the best,

I don't see a tag property on the WindowClosedEventArgs?
I only see DialogResult and PromptResult?

My scenario is...

I'm in Function A which has a parameter of say _resultObject
Under a certain condition I want to prompt for a response and if the response is true execute function B but function B needs access to _resultObject. ATM the only way i can do this is to make a member variable.
So what I want to be able to do is as follows:

public void MyFunctionA(var resultObject)
{
    if (needtoAskAQuestion)
    {
        RadWindow.Confirm(new EventHandler<WindowClosedEventArgs>(OnMyFunctionAClosed(arg=resultObject));
    }
    else
    {
        FunctionB(resultObject);
    }

 

 

protected override void OnMyFunctionBClosed(object sender, WindowClosedEventArgs e)

 

{

 

 

    if (e.DialogResult == true) 
    {
        FunctionB(e.arg);
    }
}

 

    private void FunctionB(var resultObject)
    {
           // do stuff with result object.
    }
}

Hello Bronwen,

 You could also use an anonymous method instead - this will let you use your local variable. Please refer to the following code:

public void MyFunctionA(var resultObject)
{
    if (needtoAskAQuestion)
    {
        RadWindow.Confirm(new EventHandler<WindowClosedEventArgs>((s, e) =>
{
if (e.DialogResult == true)
    {
        FunctionB(resultObject);
    }
});
    }
    else
    {
        FunctionB(resultObject);
    }

    private void FunctionB(var resultObject)
    {
           // do stuff with result object.
    }

Hope this helps!
