  // Create an instance of the CreationFilter. This needs to be Form-Level so // we can catch the event that fires when the CheckBox is clicked. CheckBoxOnHeader_CreationFilter aCheckBoxOnHea

using System;using System.Drawing;using System.Collections;using System.ComponentModel;using System.Windows.Forms;using System.Data;using Infragistics.Win;using Infragistics.Win.UltraWinTree;u

private void AfterEditorButtonCloseUp(object sender, EditorButtonEventArgs e){ if (e.Context != null) { var cell = e.Context as UltraGridCell; }}

cell.Band.Layout.Gridrow.Band.Layout.Grid

重点是把要放Tree的那个单元格用一个全局变量保存,在事件中好给它赋值using System;using System.Collections.Generic;using System.Data;using System.Linq;using System.Windows.Forms;using Infragistics.Win;using Infragistics.Win.Ultr

先说一下客户的需求，有点古怪就是在某一列中，放一个类似的CheckBoxList的控件那样，可以多选的东东，选择几项保存的时候就插几条记录进数据库，其余的字段内容一样。但是图上这个有CheckBoxList那行是Add上去的(Grid.DisplayLayout.

首先要说的是这两句达不到我要的效果comboRevision.DisplayLayout.Bands[0].HeaderVisible = false;comboRevision.DisplayLayout.Bands[0].Header.Band.H

要在控件的InitializeRow事件中写绑定的过程

/// /// 表示自定义UltraWinGrid控件的列合并模式（以显示文本合并） /// public class CustomMergedCellEvaluator : Infragistics.Win.UltraWinGrid.IMergedCellEvaluator { private string primaryKey; /// /// 获取或设置合并列的主键列的绑定名称 ///

多表头的功能实现以前就写过了，这里不再复述思路是这样:界面上左右放两个UltraGrid，都绑上同样的数据集，两个水平对齐，左边的表格只显示要固定的那几列，右边放不需要固定的列，各自不需要显示的列都隐藏掉，设置左边固定列表格滚动条隐藏GridDateTime.DisplayLayout.RowScrollRegions[0].Scrollbar = Scrollbar.Hide

<br />UltraWinGrid ->DisplayLayout-> NewColumnLoadStyle-> Hide<br />这样每次绑定隐藏列就不会出现

ultrawingrid 没有 rows clear()功能自己写了一个等同的功能代码

  using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;usin

grid.DisplayLayout.Bands[0].PerformAutoResizeCards(true);

说几点:DisplayLayout.AutoFitStyle 用这个属性起不到我要的效果 以下的代码可以起到效果  foreach (UltraGridColumn ugc in grid.DisplayLayout.Bands[0].Columns) ugc.PerformAutoResize(); 更好的一种写法:grid.DisplayLayou

private void ultraGrid1_InitializeRow(object sender, InitializeRowEventArgs e){ // Get the images that we might want to show in the cell. // You could optimize this method by caching the Bitm
