问题描述

我为组合框的列表项设置了工具提示，但我无法在cobmobox中搜索文本时出现的autocomeplete建议列表中设置工具提示。



如何设置在C＃.net Winforms应用程序中使用自动完成组合框的建议项目上的工具提示。



我尝试过的方法：

I have set tooltip for List Items of combobox but i am not able set tooltip for autocomeplete suggest list which appears while searching text in cobmobox.

How to set tooltip on suggest items with autocomplete combobox in C#.net Winforms application.

What I have tried:

<pre>private void cmbGroupPractice_DrawItem(object sender, DrawItemEventArgs e)
        {
            if (e.Index == -1)
            {
                return;
            }

            //user mouse is hovering over this drop-down item, update its data  
            if ((e.State & DrawItemState.Selected) == DrawItemState.Selected)
            {
                // this tooltip simply shows the displayed text to the right of the drop-down  box, customize as needed  

                //toolTip1.Show(cmbGroupPractice.Items[e.Index].ToString(), cmbGroupPractice, e.Bounds.Right - 100 + e.Bounds.Height, e.Bounds.Top + e.Bounds.Width - 100);
                toolTip1.Show(cmbGroupPractice.Items[e.Index].ToString(), cmbGroupPractice, e.Bounds.Right - 100 + e.Bounds.Height, e.Bounds.Top + e.Bounds.Width - 100);
                
            }
            e.DrawBackground();
            // draw text strings  
            e.Graphics.DrawString(
                cmbGroupPractice.Items[e.Index].ToString(),
                e.Font,
                Brushes.Black, new Point(e.Bounds.X, e.Bounds.Y));
        }
