Hi,

I would like to be able to begin typing the moment the MultiColumnComboBox has focus, which is not possible at the moment. I need to click in the control or tap Tab a second time before I can begin typing.

Best Regards,
Hans

Hello Hans,

I've tested two scenarios based on your description.

The first one was to click on the text input part of the control. In this case the focus is given to the input field and you can type right away.
The second scenario was to focus the control using its Focus() method. In this case you cannot just start typing because the focus doesn't propagate to the input field. In order to focus this you can use the GotFocus event of the RadMultiColumnComboBox control to manually set the focus to the text input. Here is an example in code:

private void multiColumnComboBox_GotFocus(object sender, RoutedEventArgs e)

{

    var tb = this.multiColumnComboBox.FindChildByType<RadWatermarkTextBox>();

    tb.Focus();

}

If this doesn't help, can you please tell me how exactly you focus the control, and what is its setup?

Hello Martin,

My MultiColumnComboBox gets the focus by tapping the Tab key. Your second scenario was the solution to my problem. Thanks !

Hello Raneesras,

You can get the selected items of the RadMultiColumnComboBox control using its SelectedItems property.

Hello Raneesras,

To do this you can set the CloseDropDownAfterSelectionInput property of the control to True.

<telerik:RadMultiColumnComboBox CloseDropDownAfterSelectionInput="True" />

Hello Raneesras,

Note that the CloseDropDownAfterSelectionInput was introduced with UI for WPF R1 2019 (version 2019_1_116).

Hello Raneesras,

Another approach is to use the SelectionChanged event of RadMultiColumnComboBox control and its CloseDropDown() method if you have access to this API.

private void RadMultiColumnComboBox_SelectionChanged(object sender, SelectionChangeEventArgs e)

{

this.multiColumnComboBox.CloseDropDown();

}

If this doesn't work for you, there is a solution shown in the following forum.
