datagridview winform 4.0 [英] datagridview winform 4.0

问题描述

在datagridview的cellpainting事件中，我有以下代码:

Hi,
In the cellpainting event of the datagridview I have this code:

private void dgvMain_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
        {
            
            if ((e.ColumnIndex == 0) && (e.RowIndex >= 0))
            {
		...
		}

该程序不会进入if语句，因为在填充datagridview之后，我使用:
dgvMain.Columns["ID"].Visible = false;

问题:请问解决方案是什么?
谢谢

the program does not get into the if statements because after I populate the datagridview, I use:
dgvMain.Columns["ID"].Visible = false;

Question: What is the solution please?
Thanks

推荐答案

请问如何解决?"
如果将其隐藏，则不要检查第0列-因为如果它不可见，则不会被绘制.隐藏不会重新排列列或删除它们-只是使它们对用户不可见(因此不会被绘制).

尝试使用第二列或您要特别绘制的任何列.

"What is the solution please?"
Don''t check for column 0 if you hide it - because it won''t get painted if it isn''t visible. Hidiing doesn''t re-order columns, or delete them - it just makes them invisible to the user (and thus not painted).

Try using the second column, or whichever one you do want to paint specially.
