//============================================================================ //===============================以下内容为收集=============================== //============================================================================
一、改变grid的样式。
DevExpress.XtraGrid.Design.XAppearances xapp;
xapp=newDevExpress.XtraGrid.Design.XAppearances(System.Environment.GetFolderPath(System.Environment.SpecialFolder.System) + \"\\\\DevExpress.XtraGrid.Appearances.xml \");
xapp.LoadScheme(“样式名字”, gridControl1.MainView);
二、选择单元设置和取所选的值
gridView1.OptionsSelection.MultiSelectMode=GridMultiSelectMode.CellSelect; gridView1.OptionsSelection.MultiSelectMode=GridMultiSelectMode.RowSelect;// gridView1.OptionsSelection.MultiSelect = ceMultiSelect.Checked; //多行选择
三、gridview的控制
///<取当前选中的值>
string GetSelectedRows(GridView view) { string ret = \"\";
int rowIndex = -1;
if(view.OptionsSelection.MultiSelectMode == GridMultiSelectMode.RowSelect) { foreach(int i in gridView1.GetSelectedRows()) { DataRow row = gridView1.GetDataRow(i); if(ret != \"\") ret += \"\\r\\n\";
ret += string.Format(\"Company Name: {0} (#{1})\", row[\"CompanyName\"], i); } } else {
foreach(GridCell cell in view.GetSelectedCells()) { if(rowIndex != cell.RowHandle) { if(ret != \"\") ret += \"\\r\\n\";
ret += string.Format(\"Row: #{0}\", cell.RowHandle); }
ret += \"\\r\\n \" + view.GetRowCellDisplayText(cell.RowHandle, cell.Column);
rowIndex = cell.RowHandle; } } return ret; }
///<设置选中的颜色>//半透明的效果
privatevoid icbTranslucentColors_CheckedChanged(object sender, System.EventArgs e) { if(icbTranslucentColors.Checked) {
gridView1.Appearance.SelectedRow.BackColor = Color.FromArgb(30, 0, 0, 240); gridView1.Appearance.FocusedRow.BackColor = Color.FromArgb(60, 0, 0, 240); } else {
gridView1.Appearance.SelectedRow.Reset(); gridView1.Appearance.FocusedRow.Reset(); } }
///<自动添加一行>
gridView1.OptionsView.NewItemRowPosition = NewItemRowPosition.Bottom//Top/None; ///<设置gridView的按钮>
gridView1.ShowButtonMode = ShowButtonModeEnum.。。。。。。
gridView1.OptionsBehavior.Editable = chEdit.Checked; //设置按钮是否可用
///向选中的空间输入字符串 SendKeys.Send(“fsfds”); ///控件焦点
gridControl1.Focus();
四、cardView的设置
///是否现实快捷按钮CustomizeButton
cardView1.OptionsView.ShowQuickCustomizeButton=true/false; ///设置CustomizeButton的能否排序和过滤 foreach(GridColumn col in cardView1.Columns) { col.OptionsColumn.AllowSort}
foreach(GridColumn col in cardView1.Columns) { col.OptionsFilter.AllowFilter}
///card的头上的ico显示 cardView1.LayoutChanged(); ///card的头上的标题改变显示 cardView1.CardCaptionFormat =””;
///cardview显示的单个记录的折叠按钮 cardView1.OptionsView.ShowCardExpandButton=true; ///
cardView1.MaximumCardColumns =iSize cardView1.MaximumCardRows = val; cardView1.OptionsBehavior.AutoHorzWidth ///多选
cardView1.OptionsSelection.MultiSelect = ceMultiSelect.Checked;
foreach(int i in cardView1.GetSelectedRows()) { DataRow row = cardView1.GetDataRow(i); if(ret != \"\") ret += \"\\r\\n\";
ret += string.Format(\"{0} / {1} : {2:$#,0.00}\", row[\"Trademark\"], row[\"Model\"], row[\"Price\"]);
}///查看选择中的记录
CellMerging(单元格合并的效果)
///
CellMerging(单元格合并的效果)
gridView1.OptionsView.AllowCellMerge = ceMerging.Checked;
Fixed Bands(bandedGridView)
///两边固定
gridBand3 的一列的Fixed属性改成 Right,Left,None ///固定与非固定列之间的距离用
bandedGridView2.FixedLineWidth = (int)numFixedLineWidth.Value; ///设置列的颜色
打开Run Designer 选中Columns 选中要改变的列 里面有AppearanceCell （设置列的外观）和 AppearanceHeader（设置表格头的外观） 或者选中该列查看“属性”里面也有这两个属性。
///统计（gridView bandedGridView通用） 分组统计和全部统计：
全部统计：在最下面显示统计的结果。
Run Designer->Total Summary //->General 设置显示
//->Columns 对特定列来设置统计
汇总结果是否显示：可以通过gridControl的view的ShowFooter属性来设置表格下面的汇总结果 分组统计：
以上就是“分组”的 显示在每个分组下面来显示汇总结果。
通过bandedGridView2.GroupFooterShowMode=GroupFooterShowMode.。。。。设置分组的显示模式。 ///GridView设置菜单
#region Grid events
privatevoid gridView1_ShowGridMenu(object sender,
DevExpress.XtraGrid.Views.Grid.GridMenuEventArgs e) {
if(e.MenuType == DevExpress.XtraGrid.Views.Grid.GridMenuType.Column) {
DevExpress.XtraGrid.Menu.GridViewColumnMenu
menu
=
e.Menu
as
DevExpress.XtraGrid.Menu.GridViewColumnMenu;
menu.Items.Clear(); if(menu.Column != null) {
menu.Items.Add(CreateCheckItem(\"Not menu.Items.Add(CreateCheckItem(\"Fixed
Fixed\", Left\",
menu.Column, menu.Column,
FixedStyle.None, imageList2.Images[0]));
FixedStyle.Left, imageList2.Images[1]));
}
#endregion
#region New column menu
DXMenuCheckItem CreateCheckItem(string caption, GridColumn column, FixedStyle style,
}
}
menu.Items.Add(CreateCheckItem(\"Fixed
Right\",
menu.Column,
FixedStyle.Right, imageList2.Images[2]));
Image image) {
DXMenuCheckItem item = newDXMenuCheckItem(caption, column.Fixed == style, image,
newEventHandler(OnFixedClick));
}
void OnFixedClick(object sender, EventArgs e) { }
classMenuInfo { }
public MenuInfo(GridColumn column, FixedStyle style) { }
publicFixedStyle Style; publicGridColumn Column;
this.Column = column; this.Style = style;
DXMenuItem item = sender asDXMenuItem; MenuInfo info = item.Tag asMenuInfo; if(info == null) return; info.Column.Fixed = info.Style; item.Tag = newMenuInfo(column, style); return item;
#endregion
///gridview cardView自动行高
行高自动匹配
gridView1.OptionsView.RowAutoHeight = ce.Checked;
cardView1.OptionsBehavior.FieldAutoHeight = ce.Checked;
当文字多的时候（行高自动匹配设置是才有用）
repositoryItemMemoEdit1.LinesCount = ce.Checked ? 0 : 1; 设置自动全部显示该的所有行。
///BandedGridView自己订制列的方法 advBandedGridView1.ColumnsCustomization(); advBandedGridView1.DestroyCustomization();
advBandedGridView1.OptionsCustomization.AllowChangeColumnParent = edit.Checked; advBandedGridView1.OptionsCustomization.AllowChangeBandParent = edit.Checked; advBandedGridView1.OptionsCustomization.ShowBandsInCustomizationForm = edit.Checked; ///设置 图片动画模式
gridView1.OptionsView.AnimationType = (GridAnimationType)
///根据字段来分组模式 switch(index) {
void SetInterval(GridColumn column, ColumnGroupInterval interval) {
column.GroupInterval = interval;
case 0:
SetInterval(gridColumn1, ColumnGroupInterval.Alphabetical); gridColumn2.GroupInterval = ColumnGroupInterval.Alphabetical; break;
图片时（行高自动匹配设置是才有用）
repositoryItemPictureEdit1.CustomHeight = ce.Checked ? 0 : 40;
case 1:
SetInterval(gridColumn5, ColumnGroupInterval.DateMonth); break;
SetInterval(gridColumn5, ColumnGroupInterval.DateYear); break;
case 2:
case 3:
SetInterval(gridColumn5, ColumnGroupInterval.DateRange); break;
case 4:
SetSortMode(gridColumn4, ColumnSortMode.Custom); break;
SetInterval(gridColumn2, ColumnGroupInterval.Value); break;
}
default:
}
column.GroupIndex = 0;
void SetSortMode(GridColumn column, ColumnSortMode sortMode) { }
column.SortMode = sortMode; column.GroupIndex = 0;
改变分组样式
gridView1.OptionsView.GroupDrawMode = (GroupDrawMode)
///清除分组
gridView1.ClearGrouping();
foreach(GridColumn column in gridView1.Columns) {
column.GroupInterval = ColumnGroupInterval.Default; column.SortMode = ColumnSortMode.Default;
}
///CustomDataSummaries设置Grop
privatevoid numCustom_ValueChanged(object sender, System.EventArgs e) { CustomGridView.UpdateSummary(); UpdateCaptions(numCustom.Value); }
privatevoid UpdateCaptions(decimal d) {
CustomGridView.GroupSummary[0].DisplayFormat = \"(Order Count [WHERE Freight >= \" + d.ToString() + \"] = {0})\"; OnSetCaption(\"\");
gridView2.FormatConditions[0].Value1 = d; }
protectedoverridevoid OnSetCaption(string fCaption) {
fCaption = \"count records WHERE Freight >= \" + numCustom.Value.ToString(); if(Caption != null)
Caption.Text = string.Format(\"{0} ({1})\", TutorialName, fCaption); }
///下面的效果的实现
Run Designere -> Style Conditions ->Add ->column设置列的 Condition设置条件 value1,value2是参数值 代码：
publicvoid setStyle(GridView gridView) {
StyleFormatCondition cn;
cn = newStyleFormatCondition(FormatConditionEnum.Equal, gridView.Columns[\"bd_c\"], null,false);
cn.ApplyToRow = true;//false只对列其作用。
cn.Appearance.Font = newFont(AppearanceObject.DefaultFont, FontStyle.Bold); cn.Appearance.ForeColor = Color.Brown; gridView.FormatConditions.Add(cn); }
///LayoutView
layoutView1.OptionsCarouselMode.PitchAngle = (float)(((int)flatFactor.EditValue) / 360.0f * 2 * Math.PI);///卡片的高度设置flatFactor.EditValue的值(0-360)
layoutView1.OptionsCarouselMode.RollAngle = (float)(((int)rollAngle.EditValue) / 360.0f * 2 * Math.PI);/////卡片的旋转角度设置rollAngle.EditValue的值(0-360)
layoutView1.OptionsCarouselMode.BottomCardScale = ((int)endSizeScale.EditValue) / 100.0f; ///卡片的距离设置endSizeScale.EditValue的值(0-100)
layoutView1.OptionsCarouselMode.BottomCardAlphaLevel = ((int)endAlpha.EditValue) / 100.0f; ///卡片的卡片透明程度设置endAlpha.EditValue的值(0-100)
layoutView1.OptionsCarouselMode.BottomCardFading = ((int)bottomCardFading.EditValue) / 100.0f;///卡片的卡片褪色程度设置bottomCardFading.EditValue的值(0-100) layoutView1.OptionsCarouselMode.CardCount = (int)cardsCount.EditValue; ///卡片的能显示数量设置cardsCount.EditValue的值(0-20)
layoutView1.OptionsCarouselMode.InterpolationMode = (InterpolationMode) //修改卡片的方式
///layout卡片的样式在 run designer -> layout里面设置
Size originalCardMinSize = Size.Empty;
privatevoid zoomTrackBarControl1_EditValueChanged(object sender, EventArgs e) { if(originalCardMinSize == Size.Empty) originalCardMinSize = layoutView1.CardMinSize; double koeff = ((int)zoomTrackBarControl1.EditValue) / 100.0 - 0.2;
Size newSize = newSize(originalCardMinSize.Width + (int)(originalCardMinSize.Width * koeff), originalCardMinSize.Height + (int)(originalCardMinSize.Height * koeff)); layoutView1.CardMinSize = newSize;
}////设置卡片的大小的（zoomTrackBarControl1z(0-100)）
