非常简单,我觉得自己是个白痴:(
我刚开始使用DevX Controls。它的文档和示例项目是SUCKS!
我的问题是:
我的aspx页面上有一个ASPxGridView:
<dx:ASPxGridView ID="dxdgMyGrid" runat="server" AutoGenerateColumns="False" OnStartRowEditing="DxGridStartRowEditing">
<SettingsEditing Mode="PopupEditForm" PopupEditFormHeight="200px" PopupEditFormWidth="500px"
EditFormColumnCount="2" PopupEditFormHorizontalAlign="Center" PopupEditFormVerticalAlign="Middle"
PopupEditFormModal="true" />
<Columns>
<dx:GridViewDataTextColumn FieldName="MyField1" VisibleIndex="1">
<EditFormSettings VisibleIndex="0" />
<EditItemTemplate>
<dx:ASPxDateEdit ID="dxdateMyField1" runat="server">
</dx:ASPxDateEdit>
</EditItemTemplate>
</dx:GridViewDataTextColumn>
<dx:GridViewDataColumn FieldName="MyField2" VisibleIndex="4">
<EditFormSettings VisibleIndex="1" />
<EditItemTemplate>
<dx:ASPxComboBox ID="dxcomboMyField2" runat="server">
</dx:ASPxComboBox>
</EditItemTemplate>
</dx:GridViewDataColumn>
</Columns>
如何在ASPX.CS文件上访问dxdateMyField1或dxcomboMyfield2?我想写:
dxcomboMyField2.DataSource = GetMyData2List();
dxcomboMyField2.SelectedItemIndex = 0;
... etc.
非常感谢。

您无法直接访问EditItemTemplate控件。您可以在HtmlRowCreated事件中访问它们:
if (e.RowType != GridViewRowType.InlineEdit) return;
ASPxTextBox txtBox = ASPxGridView1.FindEditRowCellTemplateControl(ASPxGridView1.Columns["Name"]
as GridViewDataColumn, "ASPxTextBox1") as ASPxTextBox;
检查访问模板中包含的控件的documentation
可以将ASPxLabel.NamingContainer属性强制转换为GridViewEditItemTemplateContainer,并通过GridViewEditItemTemplateContainer.Text属性获取列值。
但我喜欢technique of using the Init/Load event handler.
当网格切换到编辑模式时,会引发ASPxLabel.Load事件。请查看本文The general technique of using the Init/Load event handler以获取实施帮助。
[ASPX]
<dxe:ASPxTextBox ID="txtName" runat="server" Width="170px" OnInit="txtName_Init">
</dxe:ASPxTextBox>
[C#]
ASPxTextBox txtName;
protected void txtName_Init(object sender, EventArgs e)
{
txtName = (ASPxTextBox)sender;
GridViewEditFormTemplateContainer container = txtName.NamingContainer as GridViewEditFormTemplateContainer;
// You can remove the if statement, and try to insert a new record. You'll catch an exception, because the DataBinder returns null reference
if (!container.Grid.IsNewRowEditing)
txtName.Text = DataBinder.Eval(container.DataItem, "CategoryName").ToString();
}
更新活动:
protected void grid_RowUpdating(object sender, DevExpress.Web.Data.ASPxDataUpdatingEventArgs e)
{
e.NewValues["CategoryName"] = txtName.Text;
}
在DevExpress上已经存在一个问题 - ASPxGridView - How to find a control inside the EditItemTemplate。

您可以使用组合框init / load事件处理程序来设置组合数据源。如果这对您不起作用,请使用FindEditRowCellTemplateControl(使用注释中的链接进行进一步说明)。
