Hello,
is there any easy way to use a custom RadGridView as grid element of the MultiColumnComboBox?
Or do I need to override the hole object chain?
in RadMultiColumnComboBox.cs
protected virtual RadMultiColumnComboBoxElement CreateMultiColumnComboBoxElement()in RadMultiColumnComboBoxElement.cs
public MultiColumnComboPopupForm MultiColumnPopupForm // not virtual?!in MultiColumnComboPopupForm.cs
protected virtual void InitializeEditorElement()in GridViewHostItem.cs
public GridViewHostItem() : base(new MultiColumnComboGridView())public MultiColumnComboGridView HostedGridView // not virtual?!...
Are there any examples?
Kind regards,
Christian

Hello Christian,
Thank you for writing.
Currently, that is not possible without actually changing the source code. I logged a request on our feedback portal and I have also voted for it on your behalf. The item is located here: IMPROVE. RadMultiColumnComboBox - expose an API for using a custom RadGridView control in the popup form. Additionally, you can subscribe to it and be updated with all of its status changes. You Telerik points are also updated accordingly.
Can you please let me know what kind of custom behavior you would like to use with the custom grid control so that I can help you in achieving it?
I hope this helps. Looking forward to your reply.

Hello Hristo,
thank you for putting this to the feedback portal.
The case was that I've a custom grid with amongst other things there are a lot of helper methods which I wanted to use with the MultiColumnComboBox Grid. I've rewrote some of them now as extension methods. But there are other custom features which I'd like to use in the future.
Kind regards,
Christian

Hello,
Has there been some update this to override the editor control for the multicolumncombobox? I am using virtual mode to optimize searches, but I need to be able to filter and sort across multiple columns while still using autocompletemode.
Thank you,

Hi LT,
Still, the item is not yet completed so I added a vote for it on your behalf. We will do our best to address the request in the R2 2019 release, scheduled for the beginning of May. Once the item is fully tested it will be merged in our branch with internal builds and the compiled assemblies can be downloaded and tested even before the official R2 version.
Let me know if you need further assistance.
