Hello,

 

Load on demand feature is requested in multicolumn combobox

 

Thanks,

We have just upgraded to the latest asp.net ajax version and excited about the new control 'RadMultiColumnComboBox', but we could not figure out how we can allow multiple selections.

Please let us know

Thanks,

Currently, the RadMultiColumnComboBox has smaller height than the AutoCompleteBox or the RadComboBox for example. 

A possible workaround can be using the following styles: 

<style>
    .RadMultiColumnComboBox .k-dropdown-wrap {
        padding: 4px 12px;
    }

    .RadMultiColumnComboBox .k-select {
        width: 1.42857143em;
        height: 1.42857143em;
        position: absolute;
        box-sizing: content-box;
        top: 0;
        bottom: 0;
        right: 0;
        left: auto;
        padding: 6px;
    }
</style>

What is the best approach to AutoSize the contents of the columns in a RadMultiColumnComboBox?  Is there a method or property I can use?

Currently, the only example for setting up virtualization is with .svc service.

The new MultiColumnComboBox control does not have any server side events.  Can you provide the same server side event that you have for the ComboBox? 

Currently, to make the MultiColumnComboBox control work in an EditTemplate of a Grid in Batch EditMode, custom implementation is needed as explained in Batch Editing Working With Templates and demonstrated here: Show short date, edit full date with batch editing.
