-- ASPxGridView 模板
---------------------------------------------------------
ASPxGridView 提供以下几种自定义的模板视图
EditForm 编辑窗口。弹出式或附加在原记录下面
DetailRow 详细行。点击后以form方式查看记录的详细信息
PreviewRow 预览行。原记录下进行简短描述
DataRow 数据行视图。每一行的内容位置都是定制的。
注：列模板请参考文档《ASPxGridView.Column》

编辑表单模板(EditForm)
示例一：两个标签页，一个用标准的编辑面板，一个展示memo字段
<Templates>
<EditForm>
<div style="padding:4px 4px 3px 4px">
<dxtc:ASPxPageControl runat="server" ID="pageControl" Width="100%">
<TabPages>
<dxtc:TabPage Text="Info" Visible="true">
<Controls>
<dxwgv:ASPxGridViewTemplateReplacement ID="Editors" ReplacementType="EditFormEditors" runat="server"></dxwgv:ASPxGridViewTemplateReplacement>
</Controls>
</dxtc:TabPage>
<dxtc:TabPage Text="Notes" Visible="true">
<Controls>
<dxe:ASPxMemo runat="server" ID="notesEditor" Text='<%# Eval("Notes")%>' Width="100%" Height="93px"></dxe:ASPxMemo>
</Controls>
</dxtc:TabPage>
</TabPages>
</dxtc:ASPxPageControl>
</div>
<div style="text-align:right; padding:2px 2px 2px 2px">
<dxwgv:ASPxGridViewTemplateReplacement ID="UpdateButton" ReplacementType="EditFormUpdateButton" runat="server"></dxwgv:ASPxGridViewTemplateReplacement>
<dxwgv:ASPxGridViewTemplateReplacement ID="CancelButton" ReplacementType="EditFormCancelButton" runat="server"></dxwgv:ASPxGridViewTemplateReplacement>
</div>
</EditForm>
</Templates>
protected string GetMemoText() {
ASPxPageControl pageControl = grid.FindEditFormTemplateControl("pageControl") as ASPxPageControl;
ASPxMemo memo = pageControl.FindControl("notesEditor") as ASPxMemo;
return memo.Text;
}
protected void grid_RowUpdating(object sender, DevExpress.Web.Data.ASPxDataUpdatingEventArgs e) {
e.NewValues["Notes"] = GetMemoText();
}
protected void grid_RowInserting(object sender, DevExpress.Web.Data.ASPxDataInsertingEventArgs e) {
e.NewValues["Notes"] = GetMemoText();
}
