[英]Winforms Designer Error “An error occured while parsing EntityName”
I'am using a custom control code for my winforms application to create a custom colored progressbar. 我正在为winforms应用程序使用自定义控件代码来创建自定义彩色进度条。 I can build it, and it works fine, BUT everytime I try to use designer, it crashes.
我可以构建它,它工作正常,但每次我尝试使用设计师,它崩溃。 "An error occured while parsing EntityName"
“解析EntityName时发生错误”
If I add from the toolbox, this is what I get . 如果我从工具箱中添加, 这就是我得到的 。
If I insert a progressbar, then rewerite the code for my control (replace progressBar
with progressBarEx
), then this is what I get . 如果我插入一个进度条,然后重新使用我的控件的代码(用
progressBar
替换progressBarEx
),那么这就是我得到的 。
The code: 编码:
using System.Drawing;
using System.Windows.Forms;
namespace Crystal
{
public class ProgressBarEx : ProgressBar
{
private SolidBrush brush = null;
public ProgressBarEx()
{
this.SetStyle(ControlStyles.UserPaint, true);
}
protected override void OnPaint(PaintEventArgs e)
{
if (brush == null || brush.Color != this.ForeColor)
brush = new SolidBrush(this.ForeColor);
Rectangle rec = new Rectangle(0, 0, this.Width, this.Height);
if (ProgressBarRenderer.IsSupported)
ProgressBarRenderer.DrawHorizontalBar(e.Graphics, rec);
rec.Width = (int)(rec.Width * ((double)Value / Maximum)) - 4;
rec.Height = rec.Height - 4;
e.Graphics.FillRectangle(brush, 2, 2, rec.Width, rec.Height);
}
}
} }
