Hello Jeff,
The main element of the
RadMaskedEditBox is initialized in the
CreateElement method of the control. The logic for adding the custom elements can be moved there. Please check my code snippet below:
public class CustomMaskedEditBox : RadMaskedEditBox
{
public override string ThemeClassName
{
get
{
return typeof(RadMaskedEditBox).FullName;
}
}
protected override void OnLoad(Size desiredSize)
{
base.OnLoad(desiredSize);
searchButton.ButtonFillElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
searchButton.ShowBorder = false;
}
RadButtonElement searchButton = new RadButtonElement();
protected override RadMaskedEditBoxElement CreateElement()
{
RadMaskedEditBoxElement baseElement = base.CreateElement();
baseElement.TextBoxItem.NullText = "Custom Mask";
searchButton.Click += new EventHandler(button_Click);
searchButton.Margin = new Padding(0, 0, 0, 0);
searchButton.Text = "Btn";
StackLayoutElement stackPanel = new StackLayoutElement();
stackPanel.Orientation = Orientation.Horizontal;
stackPanel.Margin = new Padding(1, 0, 1, 0);
stackPanel.Children.Add(searchButton);
RadTextBoxItem tbItem = baseElement.TextBoxItem;
baseElement.Children.Remove(tbItem);
DockLayoutPanel dockPanel = new DockLayoutPanel();
dockPanel.Children.Add(stackPanel);
dockPanel.Children.Add(tbItem);
DockLayoutPanel.SetDock(tbItem, Telerik.WinControls.Layouts.Dock.Left);
DockLayoutPanel.SetDock(stackPanel, Telerik.WinControls.Layouts.Dock.Right);
baseElement.Children.Add(dockPanel);
return baseElement;
}
public class SearchBoxEventArgs : EventArgs
{
private string searchText;
public string SearchText
{
get
{
return searchText;
}
set
{
searchText = value;
}
}
}
public event EventHandler<SearchBoxEventArgs> Search;
private void button_Click(object sender, EventArgs e)
{
SearchBoxEventArgs newEvent = new SearchBoxEventArgs();
newEvent.SearchText = this.Text;
SearchEventRaiser(newEvent);
}
private void SearchEventRaiser(SearchBoxEventArgs e)
{
if (Search != null)
Search(this, e);
}
}
Should you have further questions please do not hesitate to write back.
Regards,
Hristo
