单个EventArgs用于多个ComboBox [英] Single EventArgs for multiple ComboBoxes

问题描述

我创建了一个ComboBox，其DrawMode为OwnerDrawVariable。有2个事件处理程序

Hi,
I have created a ComboBox with DrawMode as OwnerDrawVariable. There are 2 event handlers

this.comboBox3.DrawItem += new System.Windows.Forms.DrawItemEventHandler(this.AllcomboBox_DrawItem);
           this.comboBox3.MeasureItem += new System.Windows.Forms.MeasureItemEventHandler(this.AllcomboBox_MeasureItem);

以下是

Those are the following

private void AllcomboBox_MeasureItem(object sender, System.Windows.Forms.MeasureItemEventArgs e)
        {
            ComboBox cBox = (ComboBox)sender;
           //My code...
        }
private void AllcomboBox_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
        {
            ComboBox cBox = (ComboBox)sender;
           //My code...

        }

这个ComBoBox工作得很好。当我有另一个ComBoBox时，我添加了一个新的事件参数，如何为我表格中的所有组合框制作一个常见的 EventArgs 。



请帮助

It worked fine for this ComBoBox. When i have another ComBoBox, i added a new event args for that, How can i make a common EventArgs for all the comboboxes in my form.

Please help

粗线更改的代码行。

Hi,

Please check this.

Bolded the changed code lines.

private void AllcomboBox_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
        {
            ComboBox cBox = (ComboBox)sender;
            DataRowView drv = (DataRowView)cBox.Items[e.Index];
            string name = drv[0].ToString();
            Font myFont = new System.Drawing.Font("Comic Sans", 11);
            e.DrawBackground();
            e.DrawFocusRectangle();
            using (Brush textBrush = new SolidBrush(e.ForeColor))
            {
                Rectangle bounds = e.Bounds;
                using (StringFormat format = new StringFormat())
                {
                    format.LineAlignment = StringAlignment.Center;
                    format.Alignment = StringAlignment.Near;
                    e.Graphics.DrawString(name, cBox.Font, textBrush, bounds, format);
                }
            }
 
        }
