Drop Down Height of GridViewComboBoxColumn

[Todd]

How do I set the height (number of entries) displayed when a user drops down a GridViewComboBoxColumn?

[Emanuel Varga]

Hello,

One very easy way to do that would be handling the CellBeginEdit event set the minimum displayed items in the dropdown there, like so:

void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
    var dropDownEditor = radGridView1.ActiveEditor as RadDropDownListEditor;
    if (dropDownEditor != null)
    {
        var dropDownEditorElement = dropDownEditor.EditorElement as RadDropDownListEditorElement;
        dropDownEditorElement.DefaultItemsCountInDropDown = 3;
    }
}

Hope this helps, if you have any other questions or comments, please let me know,

Best Regards,

Hi Emanuel,

Thanks for replying to my question.  I set the DefaultItemsCountInDropDown = 10.  But, only seven entries display in the ddl.  Is seven the maximun number entries you can display in a GridViewComboBoxColumn?

Hello Todd,

Try changing the DefaultItemsCountInDropDown with

dropDownEditorElement.MaxDropDownItems = 10;

This should show 10 items in the dropdown.

Hope this helps, if you have any other questions or comments, please let me know,
