一、常用控件样式
public void setDgv(DevExpress.XtraGrid.Views.Grid.GridView gridView1)
{
gridView1.OptionsView.ShowColumnHeaders = true; //显示列标题
gridView1.OptionsView.ShowIndicator = false; // 不显示行标题
gridView1.OptionsView.ShowGroupPanel = true; // 显示分组panel
gridView1.OptionsCustomization.AllowGroup = true; //是否允许分组
gridView1.OptionsView.ShowGroupedColumns = true; //显示分组的列
gridView1.OptionsView.ShowFilterPanelMode = DevExpress.XtraGrid.Views.Base.ShowFilterPanelMode.Never; //是否显示过滤面板
gridView1.OptionsCustomization.AllowFilter = true; //是否允许过滤
gridView1.OptionsCustomization.AllowColumnMoving = true; //是否允许移动列
gridView1.OptionsCustomization.AllowColumnResizing = false; //是否允许调整列宽
gridView1.OptionsCustomization.AllowSort = true; //是否允许排序
gridView1.OptionsSelection.EnableAppearanceFocusedCell = false; //是否允许选中单元格
gridView1.OptionsBehavior.EditorShowMode = DevExpress.Utils.EditorShowMode.Click;
gridView1.OptionsBehavior.Editable = false; //是否允许用户编辑单元格
gridView1.OptionsView.EnableAppearanceEvenRow = true; //是否启用偶数行外观
gridView1.OptionsView.EnableAppearanceOddRow = true; //是否启用奇数行外观
gridView1.OptionsMenu.EnableColumnMenu = false; //禁用列标题右键菜单
// gridView1.ClearSorting();//禁止排序
gridView1.PaintStyleName = "Flat"; //设置外观样式
DevExpress.XtraGrid.Views.Grid.GridViewAppearances Appearance1 = new DevExpress.XtraGrid.Views.Grid.GridViewAppearances(gridView1);
//列标题颜色：System.Drawing.Color.FromArgb(((int)(((byte)(198)))), ((int)(((byte)(232)))), ((int)(((byte)(243)))));
//奇数行
Appearance1.EvenRow.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(236)))), ((int)(((byte)(249)))), ((int)(((byte)(254)))));
Appearance1.EvenRow.Font = new System.Drawing.Font("宋体", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
//偶数行
Appearance1.OddRow.BackColor = System.Drawing.Color.White;
Appearance1.OddRow.Font = new System.Drawing.Font("宋体", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
//选中行
Appearance1.FocusedRow.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(254)))), ((int)(((byte)(211)))), ((int)(((byte)(128)))));
Appearance1.FocusedRow.ForeColor = System.Drawing.Color.Black;
//分组panel颜色
Appearance1.GroupPanel.BackColor = System.Drawing.Color.White;
Appearance1.GroupPanel.BackColor2 = System.Drawing.Color.CornflowerBlue;
//分组row颜色
Appearance1.GroupRow.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(198)))), ((int)(((byte)(232)))), ((int)(((byte)(243)))));
Appearance1.GroupRow.BackColor2 = System.Drawing.Color.FromArgb(((int)(((byte)(198)))), ((int)(((byte)(232)))), ((int)(((byte)(243)))));
//空白区域颜色
Appearance1.Empty.BackColor = System.Drawing.Color.LightYellow;
//列标题颜色
Appearance1.HeaderPanel.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(210)))), ((int)(((byte)(229)))), ((int)(((byte)(249)))));
//奇数行
gridView1.Appearance.EvenRow.BackColor = Appearance1.EvenRow.BackColor;
gridView1.Appearance.EvenRow.Font = Appearance1.EvenRow.Font;
//偶数行
gridView1.Appearance.OddRow.BackColor = Appearance1.OddRow.BackColor;
gridView1.Appearance.OddRow.Font = Appearance1.OddRow.Font;
//选中行
gridView1.Appearance.FocusedRow.BackColor = Appearance1.FocusedRow.BackColor; //选中的行
gridView1.Appearance.FocusedCell.BackColor = Appearance1.FocusedRow.BackColor; //选中的单元格
gridView1.Appearance.FocusedRow.ForeColor = Appearance1.FocusedRow.ForeColor; //字体颜色
gridView1.Appearance.GroupPanel.BackColor = Appearance1.GroupPanel.BackColor;
gridView1.Appearance.GroupPanel.BackColor2 = Appearance1.GroupPanel.BackColor2;
//分组row颜色
gridView1.Appearance.GroupRow.BackColor = Appearance1.GroupRow.BackColor;
// gridView1.Appearance.GroupRow.BackColor2 = Appearance1.GroupRow.BackColor2;
//空白区域颜色
gridView1.Appearance.Empty.BackColor = Appearance1.Empty.BackColor;
//列标题颜色
gridView1.Appearance.HeaderPanel.BackColor = Appearance1.HeaderPanel.BackColor;
//设置分组
gridView1.GroupSummary.Add(DevExpress.Data.SummaryItemType.Count, "分组1"); //添加分组1，如果不是count，则名称必须与字段名对应
gridView1.GroupFormat = "{1} {2}"; //默认"{0}: [#image]{1} {2}"; 字段名称：数据 计数=？
gridView1.Columns["部门名称"].GroupIndex = 0; //设置默认分组列
}
二、设置分组显示格式
gridView1.GroupFormat = "{0}: [#image]{1} {2}"; //"字段名：图标 字段值";
gridView1.GroupFormat = "{1} {2}"; //"字段值";
三、统计汇总字段
gridView1.GroupSummary.Add(DevExpress.Data.SummaryItemType.Count, "分组1"); //添加分组1，如果不是count，则名称必须与字段名对应
gridView1.GroupFormat = "{1} {2}"; //默认"{0}: [#image]{1} {2}"; 字段名称：数据 计数=？
gridView1.Columns["FieldName1"].GroupIndex = 0; //设置默认分组列
//分组列格式
gridView1.GroupSummary.Add(DevExpress.Data.SummaryItemType.Average, "id", gridView1.Columns["id"]);
gridView1.GroupSummary[1].DisplayFormat = "AVG={0:c}";
gridView1.GroupSummary.Add(DevExpress.Data.SummaryItemType.Count, "姓名", gridView1.Columns["姓名"]);
((DevExpress.XtraGrid.GridSummaryItem)gridView1.GroupSummary[gridView1.GroupSummary.Count - 1]).DisplayFormat = "小计：{0:N0}";
//展开
gridView1.ExpandAllGroups();
四、对列的操作
//设某一列只读或者不可编辑
gridView1.Columns[0].OptionsColumn.AllowEdit = false;
gridView1.Columns[0].OptionsColumn.ReadOnly = false;
//设某一列文字和标题局中显示
gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
//去掉某一列上面的自动筛选功能(Filter)
gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false;
gridView1.Columns[0].OptionsFilter.AllowFilter = false;
gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter = false;
//设置冻结列(左冻结)
gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;
//得到单元格数据(0行0列)
string ss = gridView1.GetRowCellDisplayText(0, gridView1.Columns[0]);
string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);
//设置单元格数据(将0行0列的单元格赋值123)
gridView1.SetRowCellValue(0, gridView1.Columns[0], "123");
//手动添加dev的列
DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn();
Col1.FieldName="FID";
Col1.Visible=true;
Col1.VisibleIndex=gridView1.Columns.Count;
gridView1.Columns.Add(Col1);
五、一些常用事件
//设置自动增加的行号,需要先添加给gridview添加事件CustomDrawRowIndicator
private void gridview_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
{
if (e.Info.IsRowIndicator && e.RowHandle >= 0)
e.Info.DisplayText = (e.RowHandle + 1).ToString();
}
//删除: (修改了dgvdel里的datagridviewdel方法)
public static void datagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv)
{
if (MessageBox.Show("你确定要删除选中的记录吗？", "删除提示", MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes)
{
int iSelectRowCount = Mydgv.SelectedRowsCount;
if (iSelectRowCount > 0)
{
Mydgv.DeleteSelectedRows();
}
}
}
//新增:
private void btn_add_Click(object sender, EventArgs e)
{
gridView1.AddNewRow();
}
//新增行初始值设置:
private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
{
ColumnView View = sender as ColumnView;
View.SetRowCellValue(e.RowHandle, View.Columns[0], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[0])); //复制最后一行的数据到新行
View.SetRowCellValue(e.RowHandle, View.Columns[1], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[1])); //复制最后一行的数据到新行
}
//保存 datagridviewsave
