Combobox Width

[Susan]

Hopefully this is an easy question. In my gridview, I have a combobox column. Though I have the width of the box wide enough to show an item when selected, when the user selects to change the value in the column, the drop downlist is extremely narrow. How do I correct this? I haven't found an option for the column to do this yet.

Hello Susan,

Thanks for your question.

You can easily adjust the size of the drop-down of a RadComboBoxCellElement. Consider the following code snippet:

private void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
     RadComboBoxEditor editor = this.radGridView1.ActiveEditor as RadComboBoxEditor;
     if (editor != null)
     {
         editor.DropDownSizingMode = SizingMode.UpDownAndRightBottom;
         editor.DropDownMinSize = new Size(400, 400);
     }
}

Please note that you will have to enable the sizing mode of the drop down in order to be able to modify its size.

I hope this will help you achieve the desired behavior.

Do not hesitate to write back in case of further questions.

I couldn't find the DropDownMinSize in RadComboBoxEditor. I am using WinForms Q3 2009 SP1. Where is it located?

Thanks,
Angus

Hello Angus Cheung,

Actually DropDownMinSize is a property of RadComboBoxEditorElement. Here is the correct code:

void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
    RadComboBoxEditor editor = this.radGridView1.ActiveEditor as RadComboBoxEditor;
    if (editor != null)
    {
        editor.DropDownSizingMode = SizingMode.UpDownAndRightBottom;
        ((RadComboBoxEditorElement)editor.EditorElement).DropDownMinSize = new Size(400, 400);
    }
}

If you need further assistance with this, please write back.

Sincerely yours,
