SuperGridControl 使用小技巧

1、显示行号

superGridControl1.PrimaryGrid.ShowRowGridIndex = true;

2、允许调整行头的宽度

superGridControl1.PrimaryGrid.AllowRowHeaderResize = true;

3、不允许显示行头

superGridControl1.PrimaryGrid.ShowRowHeaders = false;

4、让列头显示筛选图标

superGridControl1.PrimaryGrid.EnableFiltering = true;
superGridControl1.PrimaryGrid.EnableColumnFiltering = true;

5、在列头出显示图标

.gridColumn1.HeaderStyles.Default.Image = ((System.Drawing.Image)(resources.GetObject("resource.Image2")));

6、当鼠标移动某个列的单元格上显示图标

this.gridColumn4.CellStyles.MouseOver.Image = global::HRMS.Properties.Resources.BugUp;
this.gridColumn4.CellStyles.MouseOver.ImageAlignment = DevComponents.DotNetBar.SuperGrid.Style.Alignment.MiddleRight;
this.gridColumn4.CellStyles.SelectedMouseOver.Image = global::HRMS.Properties.Resources.BugUp;
this.gridColumn4.CellStyles.SelectedMouseOver.ImageAlignment = DevComponents.DotNetBar.SuperGrid.Style.Alignment.MiddleRight;

//如果该行设置了ReadOnly

  this.gridColumn4.CellStyles.ReadOnlyMouseOver.Image = global::HRMS.Properties.Resources.BugUp;
  this.gridColumn4.CellStyles.ReadOnlySelectedMouseOver.Image = global::HRMS.Properties.Resources.BugUp;

7、如何当单元格可以选择指定值

//先定义一个类
internal class FragrantComboBox : GridComboBoxExEditControl
{
      public FragrantComboBox(IEnumerable orderArray)
      {
           DataSource = orderArray;
      }
}

//让后在窗体构造方法中的InitializeComponent后面添加代码
string[] orderArray = { "Asterids", "Eudicots", "Rosids" };
            superGridControl1.PrimaryGrid.Columns["bm"].EditorType = typeof(FragrantComboBox);
            superGridControl1.PrimaryGrid.Columns["bm"].EditorParams = new object[] { orderArray };

8、显示子表

 //在load方法中加载数据
private void MainForm_Load(object sender, EventArgs e)
 {

            SqlConnection conn = new SqlConnection();
            conn.ConnectionString = "server=192.168.0.133;database=analyse_ipos;user id=sa;password=sa";
            conn.Open();

            DataSet set = new DataSet();

            new SqlDataAdapter("select zddm,dz,sj from ipos_zdjbb", conn).Fill(set, "zdjbb");

            superGridControl1.PrimaryGrid.DataSource = set;
            superGridControl1.PrimaryGrid.DataMember = "zdjbb";

            new SqlDataAdapter("select top 1000 id,djbh,zddm,sl,je,yyrq from ipos_qtlsd",conn).Fill(set,"qtlsd");
            new SqlDataAdapter("select q.id,q.djbh,spdm,sptm,m.sl,m.je from ipos_qtlsdmx m inner join (select top 1000 id,djbh from ipos_qtlsd) q on m.dj_id=q.id", conn).Fill(set, "qtlsdmx");
            set.Relations.Add("1", set.Tables["zdjbb"].Columns["zddm"], set.Tables["qtlsd"].Columns["zddm"]);
            set.Relations.Add("2", set.Tables["qtlsd"].Columns["id"], set.Tables["qtlsdmx"].Columns["id"]);
            conn.Close();
           
}

 //数据绑定完成事件
        private void superGridControl1_DataBindingComplete(object sender, GridDataBindingCompleteEventArgs e)
        {
            
            GridPanel panel = e.GridPanel;
            //显示行号
            panel.ShowRowGridIndex = true;
            if (panel.DataMember == "qtlsdmx")
            {
                double count = 0;
                foreach (GridElement item in panel.Rows)
                {
                    GridRow row = item as GridRow;
                    count += Convert.ToDouble(row["je"].Value);
                }

                panel.Footer.Text = string.Format("<font size='9' famaly='宋体'>总金额:<font color='Green'>{0}</font></font>", count);
            }
        }

9、设置行号的起始值（默认值为0）

superGridControl1.PrimaryGrid.RowHeaderIndexOffset = 1;

10、设置展开和收缩图标

this.superGridControl1.PrimaryGrid.CollapseImage = global::HRMS.Properties.Resources.BugRight;
this.superGridControl1.PrimaryGrid.ExpandImage = global::HRMS.Properties.Resources.BugUp;

11、显示Filter

this.superGridControl1.PrimaryGrid.Filter.Visible = true;

12、允许按列分组

this.superGridControl1.PrimaryGrid.GroupByRow.Visible = true;

13、使用分组

GridPanel panel = superGridControl1.PrimaryGrid;
panel.SetGroup(panel.Columns["Period"]);
