Modify the OpenCommand

[Missing User]

Hello!

I have an ImageEditor with custom UI and everything is working great, I just want to change some functionality of the Open button. When the user clicks on it, the OpenFileDialog open but the pre-defined file type is *.PNG and every time he need's to change it to .JPG.

Is there a way to override the OpenCommand and change the default file type of the Dialog window?

Here's the code of the button:

<telerik:RadImageEditorButton Grid.Column="0"
                              Image="/Telerik.Windows.Controls.ImageEditor;Component/Images/open.png"
                              Command="{Binding Commands.Open, ElementName=imageEditor}" />

Thanks!

Hello again,

I managed to modify the OpenCommand, I've created a class that inherits from OpenImageCommand and then override the ExecuteOverride method and implement my own logic to filter the Dialog for JPG images.

Thanks!

Hello Joao,

It is good to hear that you have managed to achieve the desired behavior by yourself. Implementing an OpenDocumentCommand which uses an OpenFileDialog with the filter you would like to have is indeed the correct way to do this.
