TextSearchMode & IsSynchronizedWithCurrentItem

[Michael]

As far as I can tell, MultiColumnComboBox does not have a TextSearchMode or IsSynchronizedWithCurrentItem property like the RadComboBox.  I'm looking to implement the Contains value of TextSearchMode. 

I also want the MultiColumbComboBox to display the current item at startup.  (using only one item at a time)  Is there another way to do these things?  Thanks.

Hello Michael,

Let me go straight to your questions.

Indeed, RadMultiColumnComboBox does not have TextSearchMode property. However, you can set its AutoCompleteMode property to "Search". The Search mode filters and highlights the data. For a string property, the Contains operator will be applied, whereas for any other type the IsEqualTo will be used.

There is no out-of-the-box way of displaying the current item at startup. What you can do is to select the current item programmatically. Please check the Selection help article for a reference.

After adding the AutoCompleteMode="Search" property and value to the xaml, the RadMultiColumnComboBox no longer shows the name of any currently selected item.  It always appears blank.   I believe this happens because I also have SelectionBoxesVisibility="Collapsed" property and value.  Is this a bug?

Also, I'm not understanding how the Selection help article would allow me to achieve displaying the name of the currently selected item (index 0) in the RadMultiColumnComboBox at startup.  Thanks.

Hi Michael,

Indeed, there is a bug when SelectionBoxesVisibility property is set to Collapsed. It is already logged into our feedback portal. You can track its progress at the following link.

As for setting the selected item - you can use the SelectedItem or SelectedIndex property of the RadMultiColumnComboBox control in order to select the needed item programmatically. For, example, you can set one of the above properties at the application startup and the RadMultiColumnComboBox should visualize the item when it is loaded.

When I try to set the SelectedIndex in code behind when SelectionBoxesVisibility property is set to Collapsed, no selected item appears.  When switching to another item, it also remains blank.  I believe there is a bug related to this as well.

Hello Michael,

This is related to the bug I already mentioned. When fixing this bug we will make sure to test this scenario as well.

Thank you for suggesting it.
