I'm trying to capture when the Enter key is pressed in a RadWatermarkTextBox without adding code to code-behind.

In the XAML I have:

            <telerik:RadWatermarkTextBox MinHeight="26"
                                         x:Name="searchCompleteBox"
                                         VerticalAlignment="Center"
                                         Text="{Binding SearchText, Mode=TwoWay}"
                                         Width="200" 
                                         WatermarkContent="Enter name, address, or ID">
                <telerik:EventToCommandBehavior.EventBindings>
                    <telerik:EventBinding Command="{Binding OnSearchCompleteBoxKeyDownCommand}"
                                     EventName="KeyDown"
                                     PassEventArgsToCommand="True" />
                </telerik:EventToCommandBehavior.EventBindings>
            </telerik:RadWatermarkTextBox>

In the ViewModel:

    private async void OnSearchCompleteBoxKeyDown(System.Windows.Input.KeyEventArgs e)
    {        
        if (e.Key == Key.Enter)
        {
            await SearchForMembersAsync();
        }
    }

The problem is SearchText is not updating. So if I type something like "smith" OnSearchCompleteBoxKeyDown fires five times, the if result is false five times, but SearchText contains an empty string instead of "smith".

SearchText is declared properly and is updated properly if I take the EventToCommandBehavior code out.  This all works properly if I use code-behind but I want to avoid that.

Hi,

does the RadWaterMarktextBox support validation at Property level like the DataGrid validation feature ? 

Thank you

Hi,

Would it be possible to have an editable RadMasked Part to mimic the RadWatermarkTextBox with floating Label?

I am trying to apply the same `Margin` style to a lot of `RadWatermarkTextBox` controls by defining the `Margin` as a Style resource:

<Window.Resources>
    <Style TargetType="{x:Type telerik:RadWatermarkTextBox}">
        <Setter Property="Margin">
            <Setter.Value>
                <Thickness Bottom="{x:Static controls:Measurements.UnrelatedDistance}" />
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>

Using the Style above makes the control look different compared to explicitly setting the `Margin` property for each control like below:

<telerik:RadWatermarkTextBox Text="Hello world">
    <telerik:RadWatermarkTextBox.Margin>
        <Thickness Bottom="{x:Static controls:Measurements.UnrelatedDistance}" />
    </telerik:RadWatermarkTextBox.Margin>
</telerik:RadWatermarkTextBox>

I am wondering what's the reason for this difference and how to use a Style resource to the make the control look like the way it does when explicitly setting the `Margin` property within the control.

Thank you.

Hi,

Would it be possible to have an editable AutoCompleteBox TextBox Part to mimic the RadWatermarkTextBox with floating Label?

Failed to focus RadWatermarkTextBox

<telerik:RadDropDownButton Margin="10 0" 
                        DropDownIndicatorVisibility="Collapsed"
                        DropDownPlacement="Mouse">
    <telerik:RadDropDownButton.DropDownContent>

Hi,

Would it be possible to have a editable RadComboBox TextBox Part to mimic the RadWatermarkTextBox with floating Label?

I am using WatermarkTextbox and somehow that looks like it is disabled,
previously I was using xctk:WatermarkTextBox in this I was using KeepWatermarkOnGotFocus="True" which was helping me.

In telerik I am not getting any property as such.

Kindly help me in this.

I want like this

<telerik:RadWatermarkTextBox
                                                HorizontalAlignment="Stretch"
                                                IsReadOnly="True"
                                                Text="{Binding MaterialPartAndName,
                                                               ValidatesOnDataErrors=True}"
                                                ToolTip="{Binding MaterialPartAndName}"
                                                cal:Message.Attach="[Event MouseEnter] = [ResetSelectedItem]"
                                                WatermarkContent="Please select a material...">

                                            </telerik:RadWatermarkTextBox>

I recently updated Telerik for WPF to the latest version. Since then I have following problem:

When I work with the designer I get this error:

[A]Telerik.Windows.Controls.RadWatermarkTextBox cannot be cast to [B]Telerik.Windows.Controls.RadWatermarkTextBox. Type A originates from 'Telerik.Windows.Controls, Version=2021.2.615.45, Culture=neutral, PublicKeyToken=...' in the context 'LoadFrom' at location 'C:\Program Files (x86)\Progress\Telerik UI for WPF R2 2021\Binaries\WPF45\Telerik.Windows.Controls.dll'. Type B originates from 'Telerik.Windows.Controls, Version=2021.2.615.45, Culture=neutral, PublicKeyToken=....' in the context 'LoadNeither' at location 'C:\Users\user\AppData\Local\Microsoft\VisualStudio\16.0_589b9641\Designer\ShadowCache\sc041jsc.3tf\nxls5byu.o3i\Telerik.Windows.Controls.dll'.

This only occurs on UserControls I want to insert somewhere. So I can use the RadWatermarkTextBox normally. But if it's in a UserControl this error is thrown.

How can I resolve this errror?

I have a WPF view that contains both watermark text boxes and multicolumn combo boxes. I would like to set their properties in the resources of the view. I am having an issue where the settings of the watermarktextbox are affecting the appearance of the multicolumncombobox. Below is my code for the settings (This is under the resources of the view)

        <Style TargetType="{x:Type telerik:RadWatermarkTextBox}">
            <Setter Property="Padding" Value="3" />
            <Setter Property="VerticalContentAlignment" Value="Center" />
            <Setter Property="telerik:StyleManager.Theme" Value="Office2019" />
            <Setter Property="Height" Value="25" />
            <Setter Property="Margin" Value="5 5 5 0" />
        </Style>

        <Style TargetType="{x:Type telerik:RadMultiColumnComboBox}">
            <Setter Property="Height" Value="25" />
            <Setter Property="Margin" Value="5,5,5,0"/>
            <Setter Property="telerik:StyleManager.Theme" Value="Office2019" />
        </Style>

Below is a screenshot of the of the view - notice the drop down icon of the combobox is off it has the downarrow on the right but then also up and down arrows to the left of the drop down arrow - i think its a scroll bar

I can fix this in a couple ways but neither are ideal:
 1) I can set the height of the multi column combobox to 31 to get rid of those scroll bars. However, I would like all of my controls to be 25

2) I can remove the Height and Margin setters from the watermarktextbox but then I would have to go through and add those properties to each individual watermark textbox in my view

is there a setter property I can add to either the resources that would cancel out the values from the watermarktextbox or is there a way to cancel them out via a setting on each individual multicolumncombobox??

Thank you!
