Question

我正在使用UpdatePanel和Ajax Tabcontainer。我有一个项目模板列，其中包含checkbox和radiobutton。基于一种类型的场，它们中的任何一个都是可见的。

<asp:GridView ID="gvAutoMatchFund" runat="server" AutoGenerateColumns="False" ClientIDMode="Static"
    AllowPaging="True" PageSize="50" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None"
    OnRowDataBound="gvAutoMatchFund_RowDataBound" BorderWidth="1px" CellPadding="3"
    onpageindexchanging="gvAutoMatchFund_PageIndexChanging" 
    Width="100%">
    <Columns>
        <asp:BoundField DataField="DYNAMO_FUNDNAME" HeaderText="Dynamo Fund Name" ItemStyle-Width="25%" />
        <asp:BoundField DataField="DYNAMO_FUNDID" HeaderText="Dynamo Fund ID" ItemStyle-Width="25%" />
        <asp:BoundField DataField="INVESTRAN_FUNDNAME" HeaderText="Investran Fund Name" ItemStyle-Width="25%" />
        <asp:BoundField DataField="INVESTRAN_SYSTEMFUNDID" HeaderText="Inv. Sys. Fund ID" />
        <asp:TemplateField ItemStyle-Width="80px" ItemStyle-HorizontalAlign="Center">
            <HeaderTemplate>
                <asp:CheckBox ID="chkSelAll" Text="Select" runat="server"  />
            </HeaderTemplate>
            <ItemTemplate>
                <asp:CheckBox ID="chkSel" runat="server" Visible='<%#(!(bool)Eval("ISMULTIPLE"))%>' />
                <asp:RadioButton ID="rdoSel" runat="server" Visible='<%#((bool)Eval("ISMULTIPLE"))%>' />                                                                    
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
    <FooterStyle BackColor="White" ForeColor="#000066" />
    <HeaderStyle BackColor="#C6E5F5" Font-Bold="True" ForeColor="#4695BD" />
    <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
    <RowStyle ForeColor="#000066" />
    <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
    <SortedAscendingCellStyle BackColor="#F1F1F1" />
    <SortedAscendingHeaderStyle BackColor="#007DBB" />
    <SortedDescendingCellStyle BackColor="#CAC9C9" />
    <SortedDescendingHeaderStyle BackColor="#00547E" />
    <EmptyDataRowStyle ForeColor="Maroon" />
</asp:GridView>

我在检查回发后填充它

 if (!Page.IsPostBack)
 {
    ...
    PopulateMyGV();
 }

当单击一个按钮时，我试图循环遍历此gridview中的每个项目，并使用FindControl方法查找复选框和单选按钮。到目前为止是有效的，但是即使选中了radiobutton，它仍然是假的。但是，如果选中或不选中复选框工作正常（为已检查属性提供正确的值）。见下面的代码

在按钮中单击

foreach (GridViewRow gvr in gvAutoMatchFund.Rows)
{   

    CheckBox chkSel = (CheckBox)gvr.FindControl("chkSel");      
    RadioButton rdoSel = (RadioButton)gvr.FindControl("rdoSel");

    if (chkSel != null)
    {
        if (chkSel.Checked)
        {
            ...
        }
    }

    if (rdoSel != null)
    {
        if (rdoSel.Checked)
        {
            ...
        }
    }

}

我错过了什么？

花了很多时间后，我们终于发现这种奇怪的行为是因为我们在RowDataBound事件中以编程方式更改了单选按钮的ID。请参阅下面的代码。

    protected void gvAutoMatchFund_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            USP_MDM_SUGGESTED_AUTOMATCH_FUNDResult objUSP_MDM_SUGGESTED_AUTOMATCH_FUNDResult = (USP_MDM_SUGGESTED_AUTOMATCH_FUNDResult)e.Row.DataItem;

            RadioButton rdoSel = (RadioButton)e.Row.FindControl("rdoSel");
            rdoSel.ID = "rdoSel_" + objUSP_MDM_SUGGESTED_AUTOMATCH_FUNDResult.DYNAMO_FUNDID
                        + "_" + objUSP_MDM_SUGGESTED_AUTOMATCH_FUNDResult.INVESTRAN_SYSTEMFUNDID
                        + "_" + objUSP_MDM_SUGGESTED_AUTOMATCH_FUNDResult.INVESTRAN_FUNDID;         

        }
    }

所以我删除了上面的逻辑并使用了以下逻辑来传递各种参数以及radiobutton

    protected void gvAutoMatchFund_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            USP_MDM_SUGGESTED_AUTOMATCH_FUNDResult objUSP_MDM_SUGGESTED_AUTOMATCH_FUNDResult = (USP_MDM_SUGGESTED_AUTOMATCH_FUNDResult)e.Row.DataItem;

            RadioButton rdoSel = (RadioButton)e.Row.FindControl("rdoSel");
            string sValue = "rdoSel_" + objUSP_MDM_SUGGESTED_AUTOMATCH_FUNDResult.DYNAMO_FUNDID
                        + "_" + objUSP_MDM_SUGGESTED_AUTOMATCH_FUNDResult.INVESTRAN_SYSTEMFUNDID
                        + "_" + objUSP_MDM_SUGGESTED_AUTOMATCH_FUNDResult.INVESTRAN_FUNDID;

            rdoSel.Attributes.Add("value", sValue);     

        }
    }

这解决了我上面描述的两个问题。

gridview中的单选按钮始终在ajax updatepanel内返回checked = false
