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

 

 1 //先定义一个类   2 internal class FragrantComboBox : GridComboBoxExEditControl   3 {   4       public FragrantComboBox(IEnumerable orderArray)   5       {   6            DataSource = orderArray;   7       }   8 }   9   10 //让后在窗体构造方法中的InitializeComponent后面添加代码  11 string[] orderArray = { "Asterids", "Eudicots", "Rosids" };  12             superGridControl1.PrimaryGrid.Columns["bm"].EditorType = typeof(FragrantComboBox);  13             superGridControl1.PrimaryGrid.Columns["bm"].EditorParams = new object[] { orderArray };

View Code

 

8、显示子表

 1  //在load方法中加载数据   2 private void MainForm_Load(object sender, EventArgs e)   3  {   4    5             SqlConnection conn = new SqlConnection();   6             conn.ConnectionString = "server=192.168.0.133;database=analyse_ipos;user id=sa;password=sa";   7             conn.Open();   8    9             DataSet set = new DataSet();  10   11             new SqlDataAdapter("select zddm,dz,sj from ipos_zdjbb", conn).Fill(set, "zdjbb");  12   13             superGridControl1.PrimaryGrid.DataSource = set;  14             superGridControl1.PrimaryGrid.DataMember = "zdjbb";  15   16             new SqlDataAdapter("select top 1000 id,djbh,zddm,sl,je,yyrq from ipos_qtlsd",conn).Fill(set,"qtlsd");  17             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");  18             set.Relations.Add("1", set.Tables["zdjbb"].Columns["zddm"], set.Tables["qtlsd"].Columns["zddm"]);  19             set.Relations.Add("2", set.Tables["qtlsd"].Columns["id"], set.Tables["qtlsdmx"].Columns["id"]);  20             conn.Close();  21              22 }  23   24  //数据绑定完成事件  25         private void superGridControl1_DataBindingComplete(object sender, GridDataBindingCompleteEventArgs e)  26         {  27               28             GridPanel panel = e.GridPanel;  29             //显示行号  30             panel.ShowRowGridIndex = true;  31             if (panel.DataMember == "qtlsdmx")  32             {  33                 double count = 0;  34                 foreach (GridElement item in panel.Rows)  35                 {  36                     GridRow row = item as GridRow;  37                     count += Convert.ToDouble(row["je"].Value);  38                 }  39   40                 panel.Footer.Text = string.Format("<font size=‘9‘ famaly=‘宋体‘>总金额:<font color=‘Green‘>{0}</font></font>", count);  41             }  42         }

 

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

1 this.superGridControl1.PrimaryGrid.CollapseImage = global::HRMS.Properties.Resources.BugRight;  2 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"]);
