c# - 在 telerik RadGridView comboboxcolumn 中更改下拉窗口

Question

我正在尝试使用 C# 和 WinForms 在 Telerik RadGridView GridViewComboBoxColumn 中设置下拉窗口的宽度。但是我只找到了设置整列宽度的方法:

foreach (GridViewColumn col in radGridView1.Columns)
{
    GridViewComboBoxColumn cbCol = col as GridViewComboBoxColumn;
    cbCol.Width = 200;
}

但这不是我想要的。我希望下拉窗口比列本身宽。我还找到了一个 DropDownStyle 属性:

cbCol.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown;
// or this
cbCol.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

但这没有任何区别(至少在视觉上对我来说没有)而且我找不到像 DropDownWidth 或类似的属性。

给你:

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);

        radGridView1.CellEditorInitialized += RadGridView1_CellEditorInitialized;
    }

    private void RadGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
    {
        RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;
        if (editor != null)
        {
            RadDropDownListEditorElement ddlElement =(RadDropDownListEditorElement ) editor.EditorElement;
            ddlElement.DropDownMinSize = new Size(200, 300);
        }
    }
