大家好...

我正在开发一个应用程序.net 2.0(Windows窗体-MDI应用程序).我需要在带有图像(已读和未读图像)的DataGridView中显示邮件.我使用了DataGridViewImage列，并且尝试将图像放在Cell_Painting事件的该列中.但是，在显示图像后，网格变得很奇怪.我可以看到网格下方的框架(透明).当我移动表格时，它将变得完美.也无法查看窗口上方的ant消息框.

一秒钟内将有近20封邮件来临，而邮件即将来临时，网格正在挂起.请任何人帮助我..

我尝试了Invalidate()和Refresh().但是nothg对我有用....

Hi All...

I am developing an application .net 2.0 (windows Forms - MDI Application.) I need to display mails in a DataGridView with Image (Read and Unread Image). I have used a DataGridViewImage column and i trying to put the image in that column in Cell_Painting event. But after displaying the image the grid is behaving weird. I can see the frame below the grid,(tranparent). When i move the Form, it will become perfect. Also am not able to view ant message box which comes over the window.

Almost 20 mails will come in one second, the grid is getting hanged while the mails are coming. Please anyonehelp me..

I tried with Invalidate() and Refresh(). But nothg works for me....
In cellpainting event of the grid............

If (.ColumnIndex = 1 )
{
e.value=Image.FromFile(f:\Read1.bmp;)
}

}
