c#-4.0 - 如何在组件一 FlexGrid 的列中添加文本和图像？

Question

我已经使用下面提到的代码片段来显示带有图像的文本。但是我无法用它显示图像。

无法从代码访问图像的路径吗？

C1.Win.C1FlexGrid.C1FlexGrid gAuditL = new C1.Win.C1FlexGrid.C1FlexGrid();
.
.
.
gAuditL.DataSource = AuditLogVieweryDT;// this is datasource
for (int i = gAuditL.Row.Fixed; i < gAuditL.Rows.Count; i++)
//foreach  row in grid 
{
 string severity = gAuditL[i, gAuditL.Cols["Severity"].Index].ToString();
 if (severity == "Information")
 {
   this.gAuditL.SetCellImage(i, 0,Image.FromFile(@".\\Resources\information.bmp"));
   this.gAuditL.SetData(i, 0, "Information");
 }
 if (severity == "Warning")
 {
   this.gAuditL.SetCellImage(i, 0, Image.FromFile(@".\\Resources\warning.bmp"));
   this.gAuditL.SetData(i, 0, "Warning");
 }
 if (severity == "Critical")
 {
   this.gAuditL.SetCellImage(i, 0, Image.FromFile(@".\\Resources\critical.bmp"));
   this.gAuditL.SetData(i, 0, "Critical");
 }
 if (severity == "Unspecified")
 {
   this.gAuditL.SetCellImage(i, 0, Image.FromFile(@".\\Resources\unspecified.bmp"));
   this.gAuditL.SetData(i, 0, "Unspecified");
 }

 this.gAuditL.Styles.Normal.ImageAlign = C1.Win.C1FlexGrid.ImageAlignEnum.LeftCenter;
 this.gAuditL.Styles.Normal.TextAlign = C1.Win.C1FlexGrid.TextAlignEnum.RightCenter;
}

            //draw text
            e.Graphics.DrawString(e.Text, e.Style.Font, Brushes.Black, e.Bounds.Location);
            e.Handled = true;
        }
