[转]GridControl各种事件

重新绘制列样式事件:gridView1_CustomDrawCell
代码:
- private void gridView1_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
- {
- if (e.Column.FieldName == "数据")
- {
- GridCellInfo GridCellInfo = e.Cell as GridCellInfo;
- if (GridCellInfo.IsDataCell && double.Parse(GridCellInfo.CellValue.ToString()) <= -30)
- e.Appearance.BackColor = Color.Yellow;
- else if (GridCellInfo.IsDataCell && double.Parse(GridCellInfo.CellValue.ToString()) > -30
- && double.Parse(GridCellInfo.CellValue.ToString()) <= -50)
- e.Appearance.BackColor = Color.Green;
- else if (GridCellInfo.IsDataCell && double.Parse(GridCellInfo.CellValue.ToString()) > -50)
- e.Appearance.BackColor = Color.Red;
- }
- }
private void gridView1_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e) { if (e.Column.FieldName == "数据") { GridCellInfo GridCellInfo = e.Cell as GridCellInfo; if (GridCellInfo.IsDataCell && double.Parse(GridCellInfo.CellValue.ToString()) <= -30) e.Appearance.BackColor = Color.Yellow; else if (GridCellInfo.IsDataCell && double.Parse(GridCellInfo.CellValue.ToString()) > -30 && double.Parse(GridCellInfo.CellValue.ToString()) <= -50) e.Appearance.BackColor = Color.Green; else if (GridCellInfo.IsDataCell && double.Parse(GridCellInfo.CellValue.ToString()) > -50) e.Appearance.BackColor = Color.Red; } }

重新计算备注事件:gridView1_CalcPreviewText
![](http://my.csdn.net/uploads/201207/21/1342858345_6956.png)
代码:
- private void gridView1_CalcPreviewText(object sender, DevExpress.XtraGrid.Views.Grid.CalcPreviewTextEventArgs e)
- {
- DataRow dr = gridView1.GetDataRow(e.RowHandle);
- e.PreviewText = dr["name"].ToString() + " : " + dr["aihao"].ToString();
- }
private void gridView1_CalcPreviewText(object sender, DevExpress.XtraGrid.Views.Grid.CalcPreviewTextEventArgs e) { DataRow dr = gridView1.GetDataRow(e.RowHandle); e.PreviewText = dr["name"].ToString() + " : " + dr["aihao"].ToString(); }

注意:GridView中大多数事件我们都会并且必须用到e这个参数,我们可以从e这个参数中获取很多信息,包括单元格、列、行、表格、GridControl的信息。我们要根据事件的意义来了解这个e是单元格级别的,或是行级别的,或是列级别的等,因为我们可以获取e的层级以上的信息,层级以下的信息就不能获取了。
e中的属性都是大同小异,其中最常用的是e.RowHandle这个属性,它代表行号的意思,通过gridView1.GetDataRow(e.RowHandle)方法可以获得这一行的数据行DataRow;并以此来做很多操作。
上述我们也说过组行的RowHandle为负数,我们通过GetDataRow获取数据行是错误的,这时我们通过gridView1.GetDataRowHandleByGroupRowHandle(e.RowHandle);方法来转化,这时得到的数据行是该组的第一行数据。在此我们需特别注意。如果加入上述转换,我们选择数据时每组第一行数据就会重复,我们要做去重复处理。
