Devexpress中Gridcontrol查找分组 ，具体代码如下所述：
private void button1_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("Group");
dt.Columns.Add("idex");
dt.Columns.Add("name");
for (int i = 0; i < 5; i++)
{
DataRow dr = dt.NewRow();
dr["Group"] = "<5";
dr["idex"] = i.ToString();
dr["name"] = "姓名" + i.ToString();
dt.Rows.Add(dr);
}
for (int i = 5; i <= 10; i++)
{
DataRow dr = dt.NewRow();
dr["Group"] = "(5,10]";
dr["idex"] = i.ToString();
dr["name"] = "姓名" + i.ToString();
dt.Rows.Add(dr);
}
for (int i = 10; i <= 15; i++)
{
DataRow dr = dt.NewRow();
dr["Group"] = "(10,15]";
dr["idex"] = i.ToString();
dr["name"] = "姓名" + i.ToString();
dt.Rows.Add(dr);
}
gridColumnNumber.FieldName = "idex";
gridColumnName.FieldName = "name";
gridColumnGroup.FieldName = "Group";
gridColumnGroup.GroupIndex = 0;
gdc.DataSource = dt;
gdv.ExpandAllGroups();
for (int i = -1; gdv.IsGroupRow(i); i--)
{
DataRow dr = gdv.GetDataRow(gdv.GetDataRowHandleByGroupRowHandle(i));
if (dr == null) return;
if (dr["Group"].ToString() == "(5,10]")
{
gdv.CollapseAllGroups();
gdv.FocusedRowHandle = i;
gdv.SetRowExpanded(i, true);
return;
}
}
}
