//============================================================================
//===============================以下内容为收集===============================
//============================================================================
一、改变grid的样式。
DevExpress.XtraGarances xapp;
xapp=newDevExpress.XtraGarances(SysteonmenlderPath(SysteonmenalFolm) + "DevExpress.XtraGrance ");
cheme(“样式名字”, gridControiew);
二、选择单元设置和取所选的值
gridVnsSelectioSelectMode=GridMultiSelectelect;
gridVnsSelectioSelectMode=GridMultiSelectlect;//
gridVnsSelectioSelect = ceMultiSeled; //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(nsSelectioSelectMode == GridMultiSelectlect) {
foreach(int i in gridVlectedRows()) {
DataRow row = gridVtaRow(i);
if(ret != "") ret += "rn";
ret += strint("Company Name: {0} (#{1})", row["CompanyName"], i);
}
}
else {
foreach(GridCell cell in lectedCells()) {
if(rowIndex != ndle) {
if(ret != "") ret += "rn";
ret += strint("Row: #{0}", ndle);
}
ret += "rn " + wCellDisplayText(ndle,
n);
rowIndex = ndle;
}
}
return ret;
}
///<设置选中的颜色>//半透明的效果
privatevoid icbTranslucentColors_CheckedChanged(object sender, SysteArgs e) {
if(icbTranslucentColors.Checked) {
gridVrance.SelectedRoolor = Color.FromArgb(30, 0, 0, 240);
gridVrance.FocusedRow.BackColor = Color.FromArgb(60, 0, 0, 240);
}
else {
gridVrance.SelectedRo();
gridVrance.FocusedRow.Reset();
}
}
///<自动添加一行>
gridVnsVieemRowPosition = NewItemRowPositm//Top/None;
///<设置gridView的按钮>
gridVuttonMode = ShowButtonModeEnum.。。。。。。
gridVnsBehavior.Editable = chEdied; //设置按钮是否可用
///向选中的空间输入字符串
SendK(“fsfds”);
///控件焦点
gridContro();
四、cardView的设置
///是否现实快捷按钮CustomizeButton
cardVnsVieuickCustomizeButton=true/false;
///设置CustomizeButton的能否排序和过滤
foreach(GridColumn col in cardVns)
{ nsColSort}
foreach(GridColumn col in cardVns)
{ nsFilFilter}
///card的头上的ico显示
cardVtChanged();
///card的头上的标题改变显示
cardVaptionFormat =””;
///cardview显示的单个记录的折叠按钮
cardVnsVieardExpandButton=true;
///
cardVumCardColumns =iSize
cardVumCardRows = val;
cardVnsBehavior.AutoHorzWidth
///多选
cardVnsSelectioSelect = ceMultiSeled;
foreach(int i in cardVlectedRows()) {
DataRow row = cardVtaRow(i);
if(ret != "") ret += "rn";
ret += strint("{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)
gridVnsVieCellMerge = ceMered;
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)numFixedLineWid;
///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bandedGridVieFooterShowMode=GroupFooterShowMode.。。。。设置分组的显示模式。
///GridView设置菜单
#region Grid events
privatevoid gridView1_ShowGridMenu(object sender,
DevExpress.XtraG.enuEventArgs e) {
if(ype == DevExpress.XtraG.enuTyn) {
DevExpress.XtraGiewColumnMenu menu = as
DevExpress.XtraGiewColumnMenu;
.Clear();
if(n != null) {
.Add(CreateCheckItem("Not
.Add(CreateCheckItem("Fixed
Fixed",
Left",
n,
n,
FixedStyle.None, imageList2.Images[0]));
FixedStyle.Left, imageList2.Images[1]));
}
#endregion
#region New column menu
DXMenuCheckItem CreateCheckItem(string caption, GridColumn column, FixedStyle style,
}
}
.Add(CreateCheckItem("Fixed Right", n,
FixedStyle.Right, imageList2.Images[2]));
Image image) {
DXMenuCheckItem item = newDXMenuCheckItem(caption, colum == style, image,
newEventHandler(OnFixedClick));
}
void OnFixedClick(object sender, EventArgs e) {
}
classMenuInfo {
}
public MenuInfo(GridColumn column, FixedStyle style) {
}
publicFixedStyle Style;
publicGridColumn Column;
n = column;
= style;
DXMenuItem item = sender asDXMenuItem;
MenuInfo info = asMenuInfo;
if(info == null) return;
= ;
= newMenuInfo(column, style);
return item;
#endregion
///gridview cardView自动行高
行高自动匹配
gridVnsVietoHeight = ed;
cardVnsBehavior.FieldAutoHeight = ed;
当文字多的时候（行高自动匹配设置是才有用）
repositoryItemMemoEdCount = ed ? 0 : 1;
设置自动全部显示该的所有行。
///BandedGridView自己订制列的方法
advBandedGridVinsCustomization();
advBandedGridVioyCustomization();
advBandedGridVinsCustomization.AllowChangeColumnParent = ed;
advBandedGridVinsCustomization.AllowChangeBandParent = ed;
advBandedGridVinsCustomization.ShowBandsInCustomizationForm = ed;
///设置 图片动画模式
gridVnsVietionType = (GridAnimationType)
///根据字段来分组模式
switch(index) {
void SetInterval(GridColumn column, ColumnGroupInterval interval) {
columInterval = interval;
case 0:
SetInterval(gridColumn1, ColumnGroupIntebetical);
gridColumnInterval = ColumnGroupIntebetical;
break;
图片时（行高自动匹配设置是才有用）
repositoryItemPictureEditmHeight = ed ? 0 : 40;
case 1:
SetInterval(gridColumn5, ColumnGroupInteonth);
break;
SetInterval(gridColumn5, ColumnGroupInteear);
break;
case 2:
case 3:
SetInterval(gridColumn5, ColumnGroupInteange);
break;
case 4:
SetSortMode(gridColumn4, ColumnSortm);
break;
SetInterval(gridColumn2, ColumnGroupInte);
break;
}
default:
}
columIndex = 0;
void SetSortMode(GridColumn column, ColumnSortMode sortMode) {
}
columode = sortMode;
columIndex = 0;
改变分组样式
gridVnsVieDrawMode = (GroupDrawMode)
///清除分组
gridVGrouping();
foreach(GridColumn column in gridVns) {
columInterval = ColumnGroupIntelt;
columode = ColumnSortlt;
}
///CustomDataSummaries设置Grop
privatevoid numCustom_ValueChanged(object sender, SysteArgs e) {
CustomGrideSummary();
UpdateCaptions(numCu);
}
privatevoid UpdateCaptions(decimal d) {
CustomGridSummary[0].DisplayFormat = "(Order Count [WHERE Freight >= " +
ing() + "] = {0})";
OnSetCaption("");
gridVtConditions[0].Value1 = d;
}
protectedoverridevoid OnSetCaption(string fCaption) {
fCaption = "count records WHERE Freight >= " + numCu.ToString();
if(Caption != null)
Capti = strint("{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(FormatCondition, gridVns["bd_c"],
null,false);
ToRow = true;//false只对列其作用。
rance.Font = newFont(AppearanceObjecltFont, FontS);
rance.ForeColor = Color.Brown;
gridVtCondition(cn);
}
///LayoutView
layoutViewnsCarouselAngle = (float)(((int)flatFactor.EditValue) / 360.0f * 2
* );///卡片的高度设置flatFactalue的值(0-360)
layoutViewnsCarouselngle = (float)(((int)rollAalue) / 360.0f * 2 *

///卡片的卡片透明程度设置endAalue的值(0-100)
layoutViewnsCarouselmCardFading = ((int)bottomCardFadinalue) /

layoutViewnsCarouselpolationMode = (InterpolationMode)
//修改卡片的方式
///layout卡片的样式在 run designer -> layout里面设置
