UltraWinGrid常用技巧

1 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);

2 判断

e.Cell.Column.Key == "字段名"

3 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;

   }

4 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));

5 选中一行

this.ultraGrid1.Rows[i].Activate();

this.ultraGrid1.Rows[i].Selected = true;

6 新增一行,并将新行设为当前行

第一种:

Infragistics.Win.UltraWinGrid.UltraGridRow row = UltraGrid1.Rows.TemplateAddRow;

UltraGrid1.ActiveRow = row;

第二种

Infragistics.Win.UltraWinGrid.UltraGridRow row = UltraGrid1.Rows.Band.AddNew();

UltraGrid1.ActiveRow = row;

­

7 接受UltraGrid中编辑的值

UltraGrid1.UpdateData();

8 UltraGrid 删除选中的行

             if (ug_list.ActiveRow != null)

             {

                 if (MessageBox.Show("确定要删除选定行吗?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1) == DialogResult.Yes)

                 {

                     ug_list.DeleteSelectedRows(true);

                 }

             }

9。添加Column

Start\Basic Settings\Data Schema\Manually Define a Schema\添加Column，命名用数据库中的字段名。

10。添加Column中文名称

Band and Column Settings\Band [0]（手动添加Column后）\Columns\选择列\Header\修改Caption属性

11。整个表的属性在Basic Settings或职能按钮中修改；单列的属性在Band中修改。

12。Basic Settings中Data Schema用于设置数据列；Presets用于调整样式；Picker用于定义一些选项属性。

5。绑定数据

this.ultraGrid1.DataSource = myDataSet.Tables[0];

数据列也可以在DataTable中设定，Column[0].ColumnName或Column[0].Caption

13。Header换行

智能按钮/Wrap Header Text 设为true，默认为不换行的

14。排序：Picker/Filtring/Allow

15。分组：Picker/OutLook GroupBy/Active

16。编辑：Picker/Update

17。多行表头：Column Arrangement Designer/Add Group/Add Level/把相应的列拖到组下面，

18。隐藏列：Column Arrangement Designer/Show Hide

19。单列不可编辑：Band[0]/Column/AllowEdit

20。单击单元格选择状态：Band[0]/Column/CellClickAction

21。绑定控件：Band[0]/Column/EditorControl

22。单元格合并：Band[0]/Column/MergedCell。。。

23。定住不滚动列：Picker/Fixed Header

24。增加行：

     this.ultraGrid1.Rows.Band.AddNew();

     this.ultraGrid1.Rows[this.ultraGrid1.Rows.Count - 1].Cells["REC_ID"].Value = CommomFun.GetID();

25。删除行：

   if (this.ultraGrid1.Rows.Count <= 0)

                 {

                     MessageInfo.ShowMessage("m_system_client_0009");

                     return ;

                 }

                 #endregion

                 if (this.ultraGrid1.ActiveRow != null)

                 {

                     this.ultraGrid1.ActiveRow.Selected = true;

                 }

                 if (MessageInfo.ShowMessage("m_system_client_0003", MessageBoxButtons.YesNo) == DialogResult.Yes)

                 {

                     bool blnDeleted = false;

                     for (int i = 0; i < this.ultraGrid1.Rows.Count; i++)

                     {

                         if (this.ultraGrid1.Rows[i].Selected || this.ultraGrid1.Rows[i].IsActiveRow)

                         {

                             if (this.ultraGrid1.Rows[i].Delete(false))

                             {

                                 i--;

                             }

                             blnDeleted = true;

                         }

                     }

                  

                     if (!blnDeleted)

                     {

                         MessageInfo.ShowMessage("m_system_client_0009");

                     }

                 }

26 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;

   }

27 UltraGrid 删除选中的行

this.ultraGrid1.DeleteSelectedRows(false);

28 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);

29 格子的属性

   e.Cell.Column.Key   :字段名

   e.Cell.Column.Header.Caption   :字段标题名

   e.Cell.column.Band.Key :Band(表)的名称；

30 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;

   }

31 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));

32 选中一行

this.ultraGrid1.Rows[i].Activate();

       this.ultraGrid1.Rows[i].Selected = true;

33 空行

     是否显示空行this.UltraGrid1.DisplayLayout.EmptyRowSettings.ShowEmptyRows = true;

     空行样式

     EmptyRowStyle style = (EmptyRowStyle)this.ultraComboEditorStyle.Value;

     this.UltraGrid1.DisplayLayout.EmptyRowSettings.Style = style;

34.保存属性设置

   this.gridOne.DisplayLayout.Save(objLayout1,Infragistics.Win.UltraWinGrid.PropertyCategories.All);

35 重置属性设置

   this.gridOne.DisplayLayout.Load(this.m_objFancyLayout, Infragistics.Win.UltraWinGrid.PropertyCategories.All);

­

36.不同行样式

   this.gridRowProperties.DisplayLayout.Override.RowAlternateAppearance.BackColor = Color.Cyan;

   this.gridRowProperties.DisplayLayout.Override.RowAlternateAppearance.ForeColor = Color.DarkBlue;

37.下拉框UltraDropDown

   this.UltraDropDown1.ValueMember = "ProductID";

   this.UltraDropDown1.DisplayMember = "Name";

   this.ultraGrid1.DisplayLayout
