Text manipulation in WatermarkTextBox

[Christie Admin]

Hi,

I'm on .Net 4.0 and I use Telerik V2014.1.331.40 and I would like to know how I can access the RadWatermarkTextBox inside the control? For my scenario, I need to do some manipulation on the text inside the RadWatermarkTextBox.

Thank's
Alain

Hello Alain,

Can you give us more information about what kind manipulation you want to achieve?

If you need to modifye the style of the control you can find all resources in the Themes.Implicit folder under your installation directory. For RadWatermartTextBox, you need to check the Themes.Implicit\OfficeBlack\Themes\Telerik.Windows.Controls.xaml file.

I hope it helps.

Hi Masha,

with the RadAutoCompleteBox and I use a AutoCompleteBoxGroupingFilteringBehavior. What I'm trying to do is to filter the contain of the dropdown depending ON which word the carret is into the the AutoCompeteBox.

Let me show an example:

AutoCompleteBox text: Masha Alain User1 User2 User3

So, if the carret is on the "Alain" word, I need to display in the dropdown only the items which contain the "Alain" word. Samething for "Masha". If the user enter the following: "User1 User2 Masha+Alain User3" and the carrte is on "Masha", I need to display in the dropdown on the items containing the "Masha" and "Alain".

Thank's
Alain

Hello Alain,

In order to find RadWatermarkTextBox inside RadAutoCompleteBox, you can use ChildrenOfType<T> method, for example:

private void RadAutoCompleteBox_Loaded(object sender, RoutedEventArgs e)
{
    var autoCompleteBox = sender as RadAutoCompleteBox;
    if (autoCompleteBox != null)
    {
        var watermark = autoCompleteBox.ChildrenOfType<RadWatermarkTextBox>().FirstOrDefault();
        if(watermark != null)
        {
            // watermark is found!
        }
    }
}

Hope this helps!
