一：第一列显示行号 CustomDrawRowIndicator
this.gridViewDevice.IndicatorWidth = 40;
this.gridViewDevice.CustomDrawRowIndicator += new DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventHandler(gridViewDevice_CustomDrawRowIndicator);
void gridViewDevice_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
{
if (e.Info.IsRowIndicator && e.RowHandle >= 0)
{
e.Info.DisplayText = Convert.ToString(Convert.ToInt32(e.RowHandle.ToString()) + 1);
}}
二：不同行显示不同背景颜色 RowStyle
private void gridView1_RowStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)
{
DevExpress.XtraGrid.Views.Grid.GridView view = sender as DevExpress.XtraGrid.Views.Grid.GridView;
if (e.RowHandle >= 0)
{
String category = view.GetRowCellDisplayText(e.RowHandle, view.Columns["字段名称"]);
if (category == "显示颜色的条件")
{
e.Appearance.BackColor = Color.LightGreen;
}
}}
三：不同单元格显示不同背景色 RowCellStyle
private void gridView1_RowCellStyle(object sender, RowCellStyleEventArgs e)
{
GridView View = sender as GridView;
if (e.Column.FieldName == "绑定的字段")
{
string category = View.GetRowCellDisplayText(e.RowHandle, View.Columns["字段名称"]);
if (category == "满足字段的条件")
{
e.Appearance.BackColor = Color.LightCoral;
e.Appearance.BackColor2 = Color.LightPink;
}}}
四：添加列图标 CustomUnboundColumnData
添加图标列，FieldName设为Image
Hashtable Images = new Hashtable(); //图标集合
private void gridView1_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
{
if (e.Column.FieldName == "Image" && e.IsGetData)
{
String 条件 = (String)((DataRowView)e.Row)["查找字段"].ToString();
String fileName = "1.png";
switch (条件)
{
case "1":
fileName = "1.png";
break;
case "2":
fileName = "2.png";
break;
}
if (!Images.ContainsKey(fileName))
{
Image img = null;
try
{
String filePath = System.IO.Path.Combine(Application.StartupPath.ToString(), @"Resource\Icon", fileName);
img = Image.FromFile(filePath);
}
catch{}
Images.Add(fileName, img);
}
e.Value = Images[fileName];
}
}
