How to change background color of a cell in Devexpress Grid?
提问by Lavy
I have a devexpress xtragrid with 40 columns. I compare each cell value with other and if it is different then I want to change the cell background color. I try with GridViewInfo but it only takes the columns that are visible on the screen.But I want to do for all the columns.(Not with RowCellStyle) Do you have a solution for that? Thank you!
我有一个带有 40 列的 devexpress xtragrid。我将每个单元格值与其他值进行比较，如果不同，那么我想更改单元格背景颜色。我尝试使用 GridViewInfo 但它只需要屏幕上可见的列。但我想为所有列做。（不是 RowCellStyle）你有解决方案吗？谢谢！

Hook onto the RowStyle event of your xtragrid.
连接到 xtragrid 的 RowStyle 事件。
private void maintainDataControl_RowStyle(object sender, RowStyleEventArgs e)
{
if (e.RowHandle >= 0)
{
GridView view = sender as GridView;
// Some condition
if((string)view.GetRowCellValue(
e.RowHandle, view.Columns["SomeRow"]).Equals("Some Value"))
{
e.Appearance.BackColor = Color.Green;
}
}
}

You need to handle the CustomDrawCellof your GridView, here is a snip of code that change the color of the Name column, based on an other column valoe (age column)
您需要处理GridView的CustomDrawCell，这里是一段代码，根据其他列值（年龄列）更改名称列的颜色
private void gridView_CustomDrawCell(object sender, RowCellCustomDrawEventArgs e)
{
if (e.Column == colName)
{
var age = Convert.ToInt32(gridView.GetRowCellValue(e.RowHandle, colAge));
if (age < 18)
e.Appearance.BackColor = Color.FromArgb(0xFE, 0xDF, 0x98);
else
e.Appearance.BackColor = Color.FromArgb(0xD2, 0xFD, 0x91);
}
}
Good luck
祝你好运
