1.添加表头
sgc.PrimaryGrid.SelectionGranularity = SelectionGranularity.Row;//点击选中一行 DevComponents.DotNetBar.SuperGrid.GridColumn gc = null; gc = new DevComponents.DotNetBar.SuperGrid.GridColumn("ID"); sgc.PrimaryGrid.Columns.Add(gc); gc = new DevComponents.DotNetBar.SuperGrid.GridColumn("类型编码"); sgc.PrimaryGrid.Columns.Add(gc);
2.添加数据 加一行
sgc.PrimaryGrid.Rows.Add(new GridRow(new object[] { "a", "b" }));//也就是加一个GrindRow对像
3.设点击选中一行后 取第一行第一列的值
SelectedElementCollection col = sgc.PrimaryGrid.GetSelectedRows();//选中的行集合 if (col.Count > 0) { GridRow gr = (col[0] as GridRow);//把第一行转为GridRow fac.ID = int.Parse(gr.Cells[0].Value.ToString());//取第一列的Value转一下 //等效于int id= int.Parse((sgc.PrimaryGrid.GetSelectedRows()[0] as GridRow).Cells[0].Value.ToString()); }
4.增加一个下拉框
4.1
using DevComponents.DotNetBar.SuperGrid; using System; using System.Windows.Forms; namespace TestForm { public partial class Form1 : Form { public Form1() { InitializeComponent(); this.Load += Form1_Load; } private void Form1_Load(object sender, EventArgs e) { GridColumn col = new GridColumn("这是一个下拉框"); col.HeaderText = "这是一个下拉框"; col.Name = "这是一个下拉框"; col.AutoSizeMode = ColumnAutoSizeMode.DisplayedCells; col.EditorType = typeof(DefineGridCB); col.EditorParams = new object[] { new object[] { "第一个", "第二个" } }; superGridControl1.PrimaryGrid.Columns.Add(col); } //自定义控件 public class DefineGridCB : GridComboBoxExEditControl { public DefineGridCB(object source) { DataSource = source; } } //增加一行 private void buttonItem1_Click(object sender, EventArgs e) { superGridControl1.PrimaryGrid.NewRow(true); } } }
4.2 方法二 上边不传值 直接给一个无参构造方法
public class ThisGridComboBoxControl : GridComboBoxExEditControl { public ThisGridComboBoxControl() { CustomList cl = new CustomList("BSC201Compare"); DataTable dt = cl.GetList();//这里我是执行了一个sql查询 有符号和名称两个列 反回一个dataTable DataSource = dt; DisplayMember = "名称"; ValueMember = "符号"; DropDownStyle = ComboBoxStyle.DropDownList; DropDownColumns = "名称|符号"; MaxDropDownItems = 8; } }
4.2效果 
5.增加一个按钮
using DevComponents.DotNetBar.SuperGrid; using System; using System.Windows.Forms; using DevComponents.DotNetBar.SuperGrid.Style; namespace TestForm { public partial class Form1 : Form { public Form1() { InitializeComponent(); this.Load += Form1_Load; } private void Form1_Load(object sender, EventArgs e) { GridColumn col = new GridColumn("这是一个下拉框"); col.HeaderText = "这是一个下拉框"; col.Name = "这是一个下拉框"; col.AutoSizeMode = ColumnAutoSizeMode.DisplayedCells; col.EditorType = typeof(DefineGridCB); col.EditorParams = new object[] { new object[] { "第一个", "第二个" } }; superGridControl1.PrimaryGrid.Columns.Add(col); col = new GridColumn("这是一个按钮"); col.AutoSizeMode = ColumnAutoSizeMode.DisplayedCells; col.EditorType = typeof(DefineGridButtonX); superGridControl1.PrimaryGrid.Columns.Add(col); } /// <summary> /// 自己定义按钮 /// </summary> public class DefineGridButtonX : GridButtonXEditControl { public DefineGridButtonX() { this.Click += DefineGridButtonX_Click; } private void DefineGridButtonX_Click(object sender, EventArgs e) { MessageBox.Show("1"); } /// <summary> /// 控件属性 /// </summary> /// <param name="cell"></param> /// <param name="style"></param> public override void InitializeContext(GridCell cell, CellVisualStyle style) { base.InitializeContext(cell, style); this.Text = "这是一个按钮"; } } //自定义下拉控件 public class DefineGridCB : GridComboBoxExEditControl { public DefineGridCB(object source) { DataSource = source; } } //增加一行 private void buttonItem1_Click(object sender, EventArgs e) { superGridControl1.PrimaryGrid.NewRow(true); } } }
改变按钮颜色-依照别的列改变 在class的初始化中做如下操作
public override void InitializeContext(GridCell cell, CellVisualStyle style) { base.InitializeContext(cell, style);
BackColor = Color.Transparent;//这个必须加上 不然也没有效果 if ((EditorCell.GridRow["这是一个下拉框"].Value ?? "").ToString() != "") { unchecked { ForeColor = Color.FromArgb(255, 135, 206, 235); BackColor = Color.FromArgb(255, 135, 206, 235); } ColorTable = eButtonColor.Blue; } }
4~5效果
5.superGridControl一列变化 另一列自动加载对应的数据 判断一下值变货的单元格（后来看了看还是用cellClick会更好一些）
private void SuperGridControl1_CellValueChanged(object sender, GridCellValueChangedEventArgs e) { if (e.GridCell.GridColumn.Name == "下拉列") { superGridControl1.PrimaryGrid.Columns["下拉变动列"].EditorParams = new object[] { new object[] { "wf","HH"} }; } }
6.自动行高
SPG.PrimaryGrid.DefaultRowHeight = 0;
7.去掉列头行头
sgcCondition.SPG.PrimaryGrid.ShowColumnHeader = false; // sgcCondition.SPG.PrimaryGrid.ColumnHeader.Visible = false;//效果ms和上边一个样。。。 sgcCondition.SPG.PrimaryGrid.ShowRowHeaders = false;
8.选中行 默认选中首行
SPG.PrimaryGrid.SelectionGranularity = SelectionGranularity.Row;
SPG.PrimaryGrid.InitialSelection = RelativeSelection.Row;
9.增加一行
spgDetail.PrimaryGrid.NewRow(true);
10.删除选中行
SelectedElementCollection lstGR = spgDetail.PrimaryGrid.GetSelectedRows(); if (lstGR != null) if (lstGR.Count > 0) { foreach (GridRow gr in lstGR) { spgDetail.PrimaryGrid.Rows.Remove(gr); } }
11.显示行号 且从1开始
SPG.PrimaryGrid.ShowRowGridIndex = true; SPG.PrimaryGrid.RowHeaderIndexOffset=1;
12.交换两行数据 实现上移下移
public static object[] GetRowValues(GridContainer gcRow) { object[] obj = new object[(gcRow as GridRow).Cells.Count]; for (int i = 0; i < (gcRow as GridRow).Cells.Count; i++) { obj[i] = (gcRow as GridRow)[i].Value; } return obj; } /// <summary> /// 上、下移动表格行 /// </summary> /// <param name="spg"></param> /// <param name="gr"></param> /// <param name="isUp"></param> public static bool MoveSPGRow(SuperGridControl spg, bool isUp = true) { var atRow = spg.PrimaryGrid.ActiveRow; if (atRow == null) { PublicProperties.ShowInformation("请先选中要移动的行", AlertImage.Alert, 2000);//这里是个吐司函数就是提示一下 return false; } object[] objRow = GetRowValues(atRow); if (isUp) { if (atRow.RowIndex == 0) { PublicProperties.ShowInformation("已经是第一行了，无法再向上移动", AlertImage.Alert, 2000);//这里是个吐司函数就是提示一下 return false; } var atTop = spg.PrimaryGrid.Rows[atRow.RowIndex - 1]; object[] objTop = GetRowValues(atTop as GridRow); spg.PrimaryGrid.Rows[atRow.Index - 1] = new GridRow(objRow); spg.PrimaryGrid.Rows[atRow.Index] = new GridRow(objTop); spg.PrimaryGrid.SetActiveRow(spg.PrimaryGrid.Rows[atRow.Index - 1] as GridRow); spg.PrimaryGrid.SetSelected(spg.PrimaryGrid.Rows[atRow.Index] as GridRow, false); } else { if (atRow.RowIndex == spg.PrimaryGrid.Rows.Count - 1) { PublicProperties.ShowInformation("已经是最后一行了，无法再向下移动", AlertImage.Alert, 2000);//这里是个吐司函数就是提示一下 return false; } var atBottum = spg.PrimaryGrid.Rows[atRow.RowIndex + 1]; object[] objBottum = GetRowValues(atBottum as GridRow); spg.PrimaryGrid.Rows[atRow.Index + 1] = new GridRow(objRow); spg.PrimaryGrid.Rows[atRow.Index] = new GridRow(objBottum); spg.PrimaryGrid.SetActiveRow(spg.PrimaryGrid.Rows[atRow.Index + 1] as GridRow); spg.PrimaryGrid.SetSelected(spg.PrimaryGrid.Rows[atRow.Index] as GridRow, false); } return true; } }
13.编辑superGridCell时 焦点没离开cell 点不失焦点的控件 如bar的buttonItem 那么cell里的值不会变，这里可用SetActive()函数 使焦点离开cell
SPG.PrimaryGrid.SetActive(false)
14.选中行自动行高
/// <summary> /// 只对选中行自动行高 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void SPG_RowActivated(object sender, GridRowActivatedEventArgs e) { GridRow newrow = e.NewActiveRow == null ? new GridRow() : (e.NewActiveRow as GridRow); GridRow oldrow = e.OldActiveRow == null ? new GridRow() : e.OldActiveRow as GridRow; newrow.RowHeight = 0; if (newrow != oldrow) { oldrow.RowHeight = 21;//原始宽度 } }
15.superGrid 实现选中区域上下填充
/// <summary> /// 实现superGridControl选中区上下填充 /// </summary> /// <param name="isDown">true 向下 false 向上</param> /// <param name="isFolowCursor">true激活行跟随 false 不跟随</param> private static void FillCells(SuperGridControl SPG, bool isDown = true, bool isFolowCursor = true) { //var cellSel = spgData.SPG.GetSelectedCells(); //if (cellSel != null) //{ //} var cellSel = SPG.GetSelectedCells(); if (cellSel == null) { return; } int iFirst = (cellSel.First() as GridCell).RowIndex; int iEnd = (cellSel.Last() as GridCell).RowIndex; GridRow grFirst = SPG.PrimaryGrid.Rows[iFirst] as GridRow; GridRow grEnd = SPG.PrimaryGrid.Rows[iEnd] as GridRow; for (int j = iFirst; j <= iEnd; j++) { GridRow gr = SPG.PrimaryGrid.Rows[j] as GridRow; GridRow grTmp = null; if (isDown) grTmp = grFirst; else grTmp = grEnd; for (int i = 0; i < SPG.PrimaryGrid.Columns.Count; i++) { if (gr[i].IsSelected && gr[i].AllowEdit == true) { gr[i].Value = grTmp[i].Value; } } if (isFolowCursor) gr.SetActive(); } if (isFolowCursor) grFirst.SetActive(); }
16.superGridControl出现滚动条时 追加数据 始终显示最后一条
//SPG.PrimaryGrid.ScrollToBottom()//这个不知为什么不行 看意思好像行的样子 //如果对spg有其他操作要刷新一下 spg.Refresh()不刷新下边的代码将不起作用 SPG.PrimaryGrid.LastOnScreenRowIndex = (SPG.PrimaryGrid.Rows.Last() as GridRow).Index;
17.superGridControl 列的数据居中对齐
spgLoginInfo.DefaultVisualStyles.CellStyles.Default.Alignment = DevComponents.DotNetBar.SuperGrid.Style.Alignment.MiddleCenter;
18.改变列头颜色
spgLoginInfo.DefaultVisualStyles.ColumnHeaderStyles.Default.Background.Color1 = Color.FromArgb(8, 47, 76); spgLoginInfo.DefaultVisualStyles.ColumnHeaderStyles.Default.Background.Color2 = Color.FromArgb(8, 47, 76);
19.superGridControl透明
//整体透明 superGridControl1.BackColor = Color.Transparent; //面板透明 superGridControl1.DefaultVisualStyles.GridPanelStyle.Background.Color1= Color.Transparent; //行透明 superGridControl1.DefaultVisualStyles.RowStyles.Default.Background.Color1 = Color.Transparent; //单元格透明 superGridControl1.DefaultVisualStyles.CellStyles.Default.Background.Color1 = Color.Transparent; //改变单个单元格颜色 (superGridControl1.PrimaryGrid.Rows[0] as GridRow).Cells[0].CellStyles.Default.Background.Color1 = Color.Red;
