Hi David,

Thank you for your interest in Syncfusion Products.

At present it is not possible to resize the column and the rows in the dropdown using mouse. But we can resize the column width using ColWidths and RowHeights properties of the embedded grid in the MultiColumnComboBox.ListBox. Please refer to the KB provided below that ilustrates this:

Please let me know if any concerns.

This sample does NOT show how to change column widths.

Please update the sample to show how to get to the underlying datagrid and change the column widths

Hi Eric ,

 

Thanks for the update.

 

You can achieve your requirement by using the below code snippet,

 

[c#]

 

private void multiColumnBoundCombo_DropDown(object sender, EventArgs e)

        {

            this.multiColumnComboBox1.ListBox.Grid.Model.ColWidths[1] = 120;

            this.multiColumnComboBox1.ListBox.Grid.Model.ColWidths[2] = 120;

           

        }

I have attached the sample as per your requirements in the following link. Please run the sample and let us know if it helps you.
