EevExpress中XtraGrid常用方法

1.girdView在第一列显示行号

　调整第一列的宽度 gridView1.IndicatorWidth = 40;

View Code

1 private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
2 {            
3     if (e.Info.IsRowIndicator && e.RowHandle >= 0)
4     {
5         e.Info.DisplayText = e.RowHandle.ToString();
6     }
7 }

2. 点击 gridView 列的单击事件获取自定列信息

View Code

 1 private void gridControl1_Click(object sender, EventArgs e)
 2         {
 3             if (gridView1.GetFocusedRow() != null)     
 4             { 
 5                 string name = "";
 6                 foreach (int rowId in gridView1.GetSelectedRows())
 7                 {
 8                     foreach (DevExpress.XtraGrid.Columns.GridColumn col in gridView1.VisibleColumns)
 9                     {
10 
11                         name += col.Caption+":"+gridView1.GetRowCellValue(rowId, col).ToString()+"\n";
12 
13                     }
14 
15                 }
16                 DevExpress.XtraEditors.XtraMessageBox.Show(name);                
17             }
18         }

3.根据指定条件设置单元格字体前景色

View Code

 1 private void gridView1_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
 2         {
 3             if (e.CellValue.ToString().Length > 0)
 4             {
 5                 if (e.Column.GetCaption() == "金额" && Convert.ToDouble(e.CellValue) < 100000)
 6                 {
 7                     e.Appearance.ForeColor = Color.Red;
 8                     e.Appearance.BackColor = Color.Yellow;
 9                 }
10             } 
11         }
