    I have been searching for a solution to this issue on the forums but so far, have not found anything that makes the MultiColumnComboBox display the entire Gridview component without any scroll bars.  That is to say, I do not want the width of the gridview component to be constrained by the width of the combo box itself.  I am attaching a small picture of what I am looking for as an attachment (this picture came from the the following link: and is located at the bottom of the page.)  The attachment appears to use radmultiColumnComboBox control inside a grid.  I do not know if this makes any difference in the behavior of the combo box.

    Any advice on how this can be done?

    Thank you for reading my post and any assistance you can offer.

    I discovered a way to accomplish this by setting radMultiColumnComboBox.MultiColumnComboBoxElement.DropDownWidth to the width of the Gridview "inside" the drop down.

    Hi Steven,

    Thank you for writing.

    As far as I understand you would like to have the popup of RadMultiColumnComboBox size itself according to grid size. If this is the case, you can easily achieve the desired result by setting the following property:
    radMultiColumnComboBox1.AutoSizeDropDownToBestFit = true;

    I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.
