Infragistics控件使用-UltraGrid

1 UltraGrid风格设置函数
public static void ColorGrid(ref Infragistics.Win.UltraWinGrid.UltraGrid ug)
{
//标题
ug.DisplayLayout.CaptionAppearance.TextHAlign = Infragistics.Win.HAlign.Left;
ug.DisplayLayout.CaptionAppearance.BackColor = Color.LightSteelBlue;
//边框显示
ug.DisplayLayout.BorderStyle = Infragistics.Win.UIElementBorderStyle.Solid;
//背景色
ug.DisplayLayout.Appearance.BackColor = Color.White;
//默认颜色设置
ug.DisplayLayout.Override.HeaderAppearance.BackColor = Color.LightSteelBlue;//列
ug.DisplayLayout.Override.RowSelectorAppearance.BackColor = Color.LightSteelBlue;//行
//选中颜色设置
ug.DisplayLayout.Override.SelectedCellAppearance.BackColor = Color.SteelBlue;//选中单元格
ug.DisplayLayout.Override.SelectedRowAppearance.BackColor = Color.SteelBlue;//选中行
//ActiveRowx颜色设置
ug.DisplayLayout.Override.ActiveRowAppearance.BackColor = Color.SteelBlue;
}
2 UltraGrid 删除选中的行
this.ultraGrid1.DeleteSelectedRows(false);
3 委托
this.ultraGrid1.AfterCellUpdate -= new Infragistics.Win.UltraWinGrid.CellEventHandler(this.ultraGrid1_AfterCellUpdate);
this.ultraGrid1.Rows[0].Cells["字段名"].Value = "";
this.ultraGrid1.AfterCellUpdate += new Infragistics.Win.UltraWinGrid.CellEventHandler(this.ultraGrid1_AfterCellUpdate);
4 判断
e.Cell.Column.Key == "字段名"
5 判断某列是否重复
public static bool CheckIfSame(UltraGrid ug, string colname)
{
for(int i = 0; i < ug.Rows.Count; i++)
{
for(int j = i+1; j < ug.Rows.Count; j++)
{
if(ug.Rows[i].Cells[colname].Text == ug.Rows[j].Cells[colname].Text && ug.Rows[i].Cells[colname].Text != "")
{
return true;
}
}
}
return false;
}
6 Enter切换,在form_load事件里写
this.ultraGrid1.KeyActionMappings.Add(new Infragistics.Win.UltraWinGrid.GridKeyActionMapping(System.Windows.Forms.Keys.Enter, Infragistics.Win.UltraWinGrid.UltraGridAction.NextCell, Infragistics.Win.UltraWinGrid.UltraGridState.IsCheckbox, Infragistics.Win.UltraWinGrid.UltraGridState.Cell, 0, 0));
7 选中一行
this.ultraGrid1.Rows[i].Activate();
this.ultraGrid1.Rows[i].Selected = true;
