关于FlexGrid和DataGrid合并标题、冻结、合计等问题总结

登录

因为第一次使用c1 for wpf的FlexGrid和DataGrid控件，所以有很多地方不太熟悉，在社区里请教了无数次alice版主，在此表示由衷的感谢！

DataGrid及FlexGrid区别以及选择：
DataGrid以及FlexGrid都可以做到列标题合并，都可以做到合计。
不同之处，泛泛而言，FlexGrid小巧灵活、不限于绑定亦可后台灵活操作；DataGrid基于Wpf原有DataGrid，基于绑定。
两个控件的应用场景可以参考中文官网。
C1FlexGrid: http://www.gcpowertools.com.cn/p ... onewpf/flexgrid.htm
C1DataGrid: http://www.gcpowertools.com.cn/p ... onewpf/datagrid.htm
两个component美国论坛里的2个链接：

列标题合并及冻结：
DataGrid以及FlexGrid都可以做到列标题合并，但合并的方式不同(也许我仅知道这些方式)
DataGrid合并：

<c1:DataGridRowHeaderColumn Header="[生产厂区, 基本信息, 基本信息]"
Width="Auto" />
<c1:DataGridRowHeaderColumn Header="[生产厂区,生产设备, 生产机长]"
Width="Auto" />
<c1:DataGridRowHeaderColumn Header="[生产厂区,生产设备, 生产机台]"
Width="Auto" />
<c1:DataGridRowHeaderColumn Header="[目标产量, 目标产量, 目标产量]"
Width="Auto" />
<c1:DataGridTextColumn Header="[Country, Continent, 1]" />
<c1:DataGridTextColumn Header="[Country, Name, 1]" />

复制代码

在后台代码中具体代码参见：

以上示例为版主Alice所做，如果遇到全部或者部分没有合并的时候，注意一下代码：

// save headers rows and columns for later
_headerRowColumns = grid.Columns.Take(3).ToArray();
_headerColumnRows = grid.TopRows.Take(3).ToArray();

复制代码

FlexGrid合并：

FlexGrid.ColumnHeaders.Rows.Add(new Row());
FlexGrid.ColumnHeaders.Rows.Add(new Row());
FlexGrid.ColumnHeaders.Rows[0][0] = "生产厂区";
FlexGrid.ColumnHeaders.Rows[1][0] = "生产厂区";
FlexGrid.ColumnHeaders.Rows[2][0] = "生产厂区";
FlexGrid.ColumnHeaders.Columns[0].AllowMerging = true;
FlexGrid.AllowMerging = AllowMerging.All;

复制代码

其中冻结列，只有DataGrid有可拖动的冻结分割线，如下图：

合计：
DataGrid：

<c1:DataGridBoundColumn Header="开机天数" Binding="{Binding 开机天数}">
<c1:DataGridAggregate.AggregateFunctions>
<c1:DataGridAggregatesCollection>
<c1:DataGridAggregateSum ></c1:DataGridAggregateSum>
</c1:DataGridAggregatesCollection>
</c1:DataGridAggregate.AggregateFunctions>
</c1:DataGridBoundColumn>

复制代码

以上合计的格式无需特殊设置，会根据列的格式而随之而变。如果想加字符，可以ResultFormat="合计= {0}" ；

FlexGrid：

<c1:C1FlexGrid.ColumnFooterRows>
<c1:GroupRow FontWeight="Bold" FontSize="16" />
</c1:C1FlexGrid.ColumnFooterRows>

复制代码

设置columnheader列头为透明色的问题。
由于backgroud 使用了C1brushbuilder，只能把整个DataGridColumnHeaderPresenter重写来实现透明的效果。具体代码如下(或者直接运行3中提到的示例即可)：

<c1:C1DataGrid.ColumnHeaderStyle>
<Style TargetType="c1:DataGridColumnHeaderPresenter">

原来的DataGrid里数据多的时候，用虚拟化可以加快速度，我用c1DataGrid，没有这个属性了。
现在使用<c1:C1DataGrid Name="c1DataGrid1" ScrollMode="Deferred"/>即可

以后如有其他补充，随时修改

谢谢您费心的总结和反馈。
很详细。
我也会总结一篇有关C1DataGrid和C1FlexGrid的对比说明，发布博客。
完成后也请你看看。
