Question

在我的Asp项目中，我的gridview中有一个单选按钮。单选按钮仅允许用户每次选择一次。

但是，当用户单击单选按钮时，将显示确认消息，并且只有在用户单击“确定”时才会保存记录。

一切正常，但现在我遇到了问题。当用户点击“确定”时，单选按钮oncheckedchanged似乎不会触发。一旦用户点击“确定”，我该如何触发单选按钮事件？

这是我的代码：的Javascript

function RadioCheck(rb) {
    var gv = document.getElementById('Content_PageContent_ucSubMenuItem_module_sales_customer_submenuitem_contactpersonlist_ascx_gvContactPersonList');var rbs = gv.getElementsByTagName("input");
    for (var i = 0; i < rbs.length; i++) {
        if (rbs[i].type == "radio") {
            //if radio button is check but not the selected value then false
            if (rbs[i].checked && rbs[i] != rb) {
                rbs[i].checked = false;
                break;
            }
        }
    }
    return confirm('Confirm Save?');

}

客户端

<asp:TemplateField HeaderText="Default" ItemStyle-HorizontalAlign="Center">
    <ItemTemplate>
        <asp:RadioButton ID="rdbtnDefault" runat="server" onclick="RadioCheck(this);" oncheckedchanged="rdbtnDefault_CheckedChanged" Visible='<%#((string)Eval("DEFAULT")) == "Y" ? false : true %>'/>
        <asp:Image ID="imgDefault" runat="server" Height="13px" ImageUrl="~/Styles/images/tick-48x48.png"  Width="13px" Visible='<% ((string)Eval("DEFAULT")) == "Y" ? true : false %>'  />
    </ItemTemplate>

服务器端

//--Register for in post back--
if (Page.ClientScript.IsClientScriptBlockRegistered(DataUCContactListing) == false) {
    ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "gvRdBtnSelectOnce", blcGenerateScript.gvRdBtnSelectOnce(gvContactPersonList.ClientID,true), true);
    ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "gvSelectAllChkBox", blcGenerateScript.gvSelectAllChkBox(gvContactPersonList.ClientID), true);
}

//**Register for script**
protected void rdbtnDefault_CheckedChanged(object sender, EventArgs e) {
    try {
        RadioButton lnBTNDone = (RadioButton)sender;
        GridViewRow row = (GridViewRow)lnBTNDone.NamingContainer;
        string accountID = gvContactPersonList.DataKeys[row.RowIndex].Values[0].ToString();
        int contactID = int.Parse(gvContactPersonList.DataKeys[row.RowIndex].Values[1].ToString());
        using (TransactionScope scope = new TransactionScope()) {
            dlcCustomerDB.updateAccountOtherDefaultN(accountID);
            dlcCustomerDB.updateAccountDefaultY(accountID, contactID);
            scope.Complete();
        }
        createGridView();
        this.Session[gbcMessageSessionID.message1] = gbcMessageAlert.saveSuccessfully;
        Response.Redirect(Request.Url.ToString());
    } catch (Exception ex) {
        logger.Error(ex.Message);
        throw;
    }
}

Radiobutton checked change event not firing in gridview
请查看此代码

<asp:RadioButton ID="rdbtnDefault" runat="server" onclick="return RadioCheck(this);" oncheckedchanged="rdbtnDefault_CheckedChanged" Visible='<%#((string)Eval("DEFAULT")) == "Y" ? false : true %>' AutoPostBack="True" />

我已添加＆＃34;返回＆＃34; RadioButton的onclick事件的关键字。

gridview事件内的确认单选按钮不会触发
