我有一个代码，其中包含一个 ASPxGridView 和一个 ASPxCheckBox 和标签，如下所示：

    <dx:ASPxGridView ID="gvTableSearchHomes" runat="server" DataSourceID="XmlHomes" Width="341px"
CssClass="tableViewSearchGrid" ClientInstanceName="gvTableSearchHomes"
AutoGenerateColumns="False" EnableRowsCache="false" KeyFieldName="ID">
<%--<Columns>--%>
    <%-- DXCOMMENT: Within ASPxGridView, add a column whose values will participate in filtering --%>
    <%--<dx:GridViewDataTextColumn FieldName="Address">
        <PropertiesTextEdit NullText="Search your home"></PropertiesTextEdit>
        <Settings AllowAutoFilterTextInputTimer="True" AutoFilterCondition="Contains" />
    </dx:GridViewDataTextColumn>
</Columns>--%>
    <Templates>
     <%--DXCOMMENT: Configure the grid's DataRow template in accordance with data source fields --%>
    <DataRow>
        <div class="gvItem">
            <dx:ASPxCheckBox ID="ChkBookList" runat="server"></dx:ASPxCheckBox>
            <dx:ASPxLabel ID="Address" runat="server" CssClass="address" Text='<%# Utils.ExtractFirstRow(Eval("Address")) %>' />
            <%--<p><dx:ASPxLabel ID="Address2" runat="server" CssClass="address2" Text='<%# Utils.ExtractSecondRow(Eval("Address")) %>' /></p>
            <p><dx:ASPxLabel ID="Price" runat="server" CssClass="price" Text='<%# Utils.GetPrice(Eval("Price")) %>' /></p>--%>
        </div>
    </DataRow>
</Templates>
<SettingsPager Visible="false" PageSize="1000" />
<Settings ShowVerticalScrollBar="True" ShowFilterRow="true" ShowColumnHeaders="false"/>
<SettingsBehavior AutoExpandAllGroups="true" AllowSelectSingleRowOnly="true" AllowSelectByRowClick="true"/>
<ClientSideEvents 
    Init="function(){ hr.TableViewLandscape_Adjust(); }" 
    EndCallback="function(){ hr.TableViewLandscape_Adjust(); }"
    SelectionChanged="OnGvTableSearchHomesSelectedChanged" />
<Styles>
    <SelectedRow ForeColor="White"></SelectedRow>
</Styles>

我无法通过 C# 代码访问这些控制。有谁能够帮我。请

Check the documentation methods to find controls in different gridview templates. e.g. ASPxGridView.FindRowTemplateControl Method

Source: http://developmentsolutionsjunction.blogspot.in/2011/11/find-controls-in-dataitemtemplate-of.html

//markup

    <dx:ASPxGridView ID="grvTest" AutoGenerateColumns="False" runat="server" DataSourceID="SqlDataSource1"
          OnHtmlRowPrepared="grvTest_HtmlRowPrepared" OnHtmlRowCreated="grvTest_HtmlRowCreated">
          <Columns>
              <dx:GridViewDataTextColumn Caption="RowID" Name="colRowID" VisibleIndex="0" Width="20px">
                  <DataItemTemplate>
                       <dx:ASPxLabel ID="lblRowID" runat="server" Text='Label'>
                      </dx:ASPxLabel>
                 </DataItemTemplate>
</dx:GridViewDataTextColumn>

//accessing template control in code-behind

protected void grvTest_HtmlRowCreated(object sender, ASPxGridViewTableRowEventArgs e)
        {
            if (e.RowType != GridViewRowType.Data) return;

            ASPxLabel label = grvTest.FindRowCellTemplateControl(e.VisibleIndex, null,
            "lblRowID") as ASPxLabel;
            label.Text = (e.VisibleIndex + 1).ToString();
        }

example code:

ASPxGridView grid = (ASPxGridView)sender;

ASPxPageControl myPages = grid.FindEditFormTemplateControl("CityEditTabs") 
                                                              as ASPxPageControl;

Some GridView code snippets to understand gridview concepts

Identify the VisibleIndex or RowHandle to get the control in particular template that you have created in your markup.

Hope above example will help you to solve your problem.

谢谢我解决了我的问题。我把这个

Protected Sub GvEncuesta_HtmlRowCreated(sender As Object, e As ASPxGridViewTableRowEventArgs)
    If (e.RowType <> GridViewRowType.Data) Then Return

    Try
        Dim cmbRespuesas As ASPxComboBox = GvEncuesta.FindRowCellTemplateControl(e.VisibleIndex, Nothing, "ASPxCmbRespuestas")

        cmbRespuesas.IncrementalFilteringMode = IncrementalFilteringMode.Contains
        cmbRespuesas.Visible = True
        cmbRespuesas.DataSource = wcfCap.RetrieveRespuestaEncuestaxEstado(1)
        cmbRespuesas.ValueField = "Cod_Respuesta"
        cmbRespuesas.TextField = "Nombre_Respuesta"
        cmbRespuesas.DataBindItems()
    Catch ex As Exception
    End Try
End Sub
