infragistcs 又

1：UltraGrid风格设置函数

public static void ColorGrid(ref Infragistics.Win.UltraWinGrid.UltraGrid dgd)

{

//标题

dgd.DisplayLayout.CaptionAppearance.TextHAlign=Infragistics.Win.HAlign.Left;

dgd.DisplayLayout.CaptionAppearance.BackColor=Color.LightSteelBlue;

//边框显示

dgd.DisplayLayout.BorderStyle=Infragistics.Win.UlElementBorderStyle.Solid;

//背景色

dgd.DisplayLayout.Appearance.BackColor=Color.White;

//默认颜色设置

dgd.DisplayLayout.Override.HeaderAppearance.BackColor=Color.LightSteelBlue;//列

dgd.DisplayLayout.Override.RowSelectorAppearance.BackColor=Color.LightSteelBlue;

//选中颜色设置

dgd.DisplayLayout.Override.SelectedCellAppearance.BackColor=Color.SteelBlue;//选中单元格

dgd.DisplayLayout.Override.SelectedRowAppearance.BaceColor=Color.SteelBlue;//选中行

//ActiveRowx颜色设置

dgd.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.ultrGrid1_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.Is Checkbox,Infragistics.Win.UltraWinGrid.UltraGridState.Cell, 0, 0));

 

7: 选中一行

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

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