在Infragistic Ultra网格中隐藏列的Windows窗体

在使用Infragistic Ultra网格时，有时会需要隐藏某些列。通过Infragistic Ultra网格提供的列选择器选项，程序员可以轻松地隐藏列。以下是如何使用列选择器选项在Infragistic Ultra网格中隐藏列的步骤：

步骤1：设置列选择器选项

在Infragistic Ultra网格的属性中，找到 “列选择器选项” 并将其设置为 “启用”。

this.ultraGrid1.DisplayLayout.Override.HeaderStyle = HeaderStyle.Standard;
this.ultraGrid1.DisplayLayout.Override.RowSelectors = DefaultableBoolean.True;
this.ultraGrid1.DisplayLayout.Override.RowSelectorWidth = 22;
this.ultraGrid1.DisplayLayout.Override.SelectTypeRow = SelectType.Single;
this.ultraGrid1.DisplayLayout.Override.SummaryDisplayArea = SummaryDisplayAreas.None;
this.ultraGrid1.DisplayLayout.ScrollBounds = ScrollBounds.ScrollToFill;
this.ultraGrid1.DisplayLayout.ScrollStyle = ScrollStyle.Immediate;
this.ultraGrid1.DisplayLayout.TabNavigation = TabNavigation.NextCell;
this.ultraGrid1.DisplayLayout.ViewStyle = ViewStyle.SingleBand;
this.ultraGrid1.Dock = DockStyle.Fill;
this.ultraGrid1.Location = new Point(0, 0);
this.ultraGrid1.RightToLeft = RightToLeft.No;
this.ultraGrid1.Size = new Size(784, 362);
this.ultraGrid1.TabIndex = 0;
this.ultraGrid1.Text = "ultraGrid1";
this.ultraGrid1.DisplayLayout.Override.SelectTypeCol = SelectType.None;
this.ultraGrid1.DisplayLayout.Override.SelectTypeRow = SelectType.Single;
this.ultraGrid1.DisplayLayout.ColumnChooserEnabled = DefaultableBoolean.True;
this.ultraGrid1.DataSource = this.dataSet1;
this.ultraGrid1.DisplayLayout.ColumnChooserDisplayStyle = Infragistics.Win.UltraWinGrid.ColumnChooserDisplayStyle.DisplayTextAndCheckboxes;

步骤2：隐藏列

1. 右击Infragistic Ultra网格的列标题。
2. 在弹出的菜单中，选择“列选择器”。
3. 在弹出的列选择器选项对话框中，取消选择需要隐藏的列。
4. 单击“确定”按钮。

private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
{
    e.Layout.Override.ColumnChooserEnabled = Infragistics.Win.DefaultableBoolean.True;
    e.Layout.Override.ColumnChooserDisplayStyle = Infragistics.Win.UltraWinGrid.ColumnChooserDisplayStyle.DisplayTextAndChecks;
}

步骤3：更新网格

在重新加载网格之前，必须先调用Infragistic Ultra网格的更新方法。以下是一个示例：

private void HideColumn()
{
    // 隐藏列
    this.ultraGrid1.DisplayLayout.Bands[0].Columns["ColumnName"].Hidden = true;
    // 更新网格
    this.ultraGrid1.Update();
}

结论

如此简单，程序员就可以在Infragistic Ultra网格中隐藏不需要的列了。只需几个简单的步骤，即可完成这项任务。
