Question

在这种方法中，如果仅未选择该行，则需要写附加条件，然后使底色变淡。我该怎么办？

private void docsActiveBandedGridView_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
{        
    DataRow dtrow = docsActiveBandedGridView.GetDataRow(e.RowHandle);

    if (dtrow != null && executeDocIDs.Contains(decimal.Parse(dtrow["ID"].ToString())))
         e.Appearance.BackColor = Color.Thistle;
}

您可以使用GridView.RowCellStyle事件来实现自己的行样式。

private void docsActiveBandedGridView_RowCellStyle(object sender, RowCellStyleEventArgs e)
{
    //If row is selected or focused then do nothing   
     if(view.IsRowSelected(e.RowHandle) || view.FocusedRowHandle == e.RowHandle)
         return;   
     DataRow dtrow = docsActiveBandedGridView.GetDataRow(e.RowHandle);

     if (dtrow != null && executeDocIDs.Contains(decimal.Parse(dtrow["ID"].ToString())))
        e.Appearance.BackColor = Color.Thistle;
 }

要避免在现有代码中绘制选定的行或重点突出的行，只需检查选定的行或重点突出的行即可，不要忘记设置e.Handled= true：

private void docsActiveBandedGridView_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
{  
    //If row is selected or focused then do nothing   
    if(view.IsRowSelected(e.RowHandle) || view.FocusedRowHandle == e.RowHandle)
      return;   
    DataRow dtrow = docsActiveBandedGridView.GetDataRow(e.RowHandle);

    if (dtrow != null && executeDocIDs.Contains(decimal.Parse(dtrow["ID"].ToString())))
         e.Appearance.BackColor = Color.Thistle;
    e.Handled = true;  //Do not forget to set Handled property to true to know the grid that you handled painting of the grid cell

}

这应该告诉您是否选择了该行：

docsActiveBandedGridView.GetSelectedRows().Contains(e.RowHandle)

如果您没有启用多选（docsActiveBandedGridView.OptionsSelection.MultiSelect = false），那么使用集中的行句柄实际上可能会更好，因为知道突出显示的行不会超过：

docsActiveBandedGridView.FocusedRowHandle == e.RowHandle

Devexpress ActiveBandedGridView选定的行？
