Editor Events of PropertyGrid .NET Component

KetticPropertyGrid WinForms control allows you embed a number of data editors into individual cells for editing and better data presentation. This .NET UI component is able to control the process of editing, including the initialization, editors for validating and events value changing. There are also advanced data editing options available with the Property Grid Control. For instance, by using this control, the users can perform a specific operation based on the user input in the editor as it is opened by handling the events of the editors.

Handling Editor Events of PropertyGrid in C#.NET

In the example below, we are going to set specific text in the PropertyGrid editor. We should press Ctrl+D and then subscribe to the KeyDown event of the KetticTextBoxElement in the EditorInitialized event handler. It is because that the PropertyGrid editors are reusable, so we must define a field to prevent from subscribing to the KeyDown once again.

C# code for handling the events of PropertyGrid editors


public PropertyGridHandlingEditorsEvents()
{
    InitializeComponent();

    this.ketticPropertyGrid1.EditorInitialized += new PropertyGridItemEditorInitializedEventHandler(ketticPropertyGrid1_EditorInitialized);
}

bool tbSubscribed = false;

void ketticPropertyGrid1_EditorInitialized(object sender, PropertyGridItemEditorInitializedEventArgs e)
{
    PropertyGridTextBoxEditor editor = e.Editor as PropertyGridTextBoxEditor;

    if (editor != null)
    {
        if (!tbSubscribed)
        {
            tbSubscribed = true;
            KetticTextBoxElement tbElement = (KetticTextBoxElement)editor.EditorElement;
            tbElement.KeyDown += new KeyEventHandler(tbElement_KeyDown);
        }
    }
}

void tbElement_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Control)
    {
        if (e.KeyCode == Keys.D)
        {
            ((KetticTextBoxElement)sender).Text = "Default setting text";
        }
    }
}
