在下拉菜单项C#中使文本变为粗体 [英] Making text bold in dropdown menu item C#

问题描述

我有以下代码，并且我想使选中的项目变为粗体或选中.我的编译器给出一个错误，告诉我它是只读的.这里有什么解决方法吗?

谢谢！

Hi,

i have the following code, and I want to make the selected item bold or checked. My compiler gives an error which tells me it is read-only. Is there some sort of workaround here?

Thanks!

private void addprinter(string printername)
{

    ToolStripItem addItem = selectPrinterToolStripMenuItem1.DropDownItems.Add(printername);
    addItem.Click += new EventHandler(printerName_Click);


}
private void printerName_Click(object sender, EventArgs e)
{
    ToolStripItem item = (ToolStripItem)sender;
    SelectedPrinterName = item.Text;
    item.Font.Bold = true; // <-- error is here
    item.Checked = true; // <--and here
    MessageBox.Show(SelectedPrinterName, "SystemInformation #208", MessageBoxButtons.OK, MessageBoxIcon.Information);
}

推荐答案

我不确定该解决方案是否适合您，但是可以使用:

问题是字体内的属性是只读的.解决方案是创建一个新字体，如下所示:

I''m not sure if this solution will work for you, but here goes:

The problem is that the properties inside the Font are read-only. The solution is to create a new font, like this:

btn1.DropDown.Font = new Font(btn1.DropDown.Font, FontStyle.Bold);

Another potential way to do this is: This One[^]. You could perhaps use the concepts in this solution to apply against your selected item.
