在C#后面的代码中打开Bootstrap模态形式

我一直在密切关注本指南中的教程，为GridView创建模式视图/编辑表单。一切似乎都在正常工作，然而，模态形式根本没有显示，<strong]屏幕变灰，但形式本身没有显示>此外，如果我检查页面的源代码，我可以看到模态表单包含我传递给它的数据

GridView代码

模态车身代码

    <div id="editModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="editModalLabel" aria-hidden="true">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
            <h3 id="editModalLabel">Edit Record</h3>
        </div>
        <asp:UpdatePanel ID="upEdit" runat="server" UpdateMode="Conditional">
            <ContentTemplate>
                <div class="modal-body">
                    <table class="table">
                        <tr><td>Country Code : <asp:Label ID="lblCountryCode" runat="server"></asp:Label></td>
                        </tr>
                        <tr>
                            <td>Population : <asp:TextBox ID="txtPopulation" runat="server"></asp:TextBox></td>
                        </tr>
                        <tr>
                             <td>Country Name:<asp:TextBox ID="txtName" runat="server"></asp:TextBox></td>
                        </tr>
                        <tr>
                            <td>Continent:<asp:TextBox ID="txtContinent1" runat="server"></asp:TextBox>
                            </td>
                        </tr>
                    </table>
                </div>
                <div class="modal-footer">
                    <asp:Label ID="lblResult" Visible="false" runat="server"></asp:Label>
                    <asp:Button ID="btnSave" runat="server" Text="Update" CssClass="btn btn-info" />
                    <button class="btn btn-info" data-dismiss="modal" aria-hidden="true">Close</button>
                </div>
            </ContentTemplate>
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="CompanyUserList" EventName="RowCommand"/>
                <%--<asp:AsyncPostBackTrigger ControlID="btnSave" EventName="Click" />--%>
            </Triggers>
        </asp:UpdatePanel>
    </div>

C#代码填充模式表单

    protected void CompanyUserList_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        int index = Convert.ToInt32(e.CommandArgument);
        GridViewRow gvrow = CompanyUserList.Rows[index];
        lblCountryCode.Text = HttpUtility.HtmlDecode("test");
        txtPopulation.Text = HttpUtility.HtmlDecode("test");
        txtName.Text = HttpUtility.HtmlDecode("test");
        txtContinent1.Text = HttpUtility.HtmlDecode("test");
        lblResult.Visible = false;
        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        sb.Append(@"<script type='text/javascript'>");
        sb.Append("$('#editModal').modal('show');");
        sb.Append(@"</script>");
        ScriptManager.RegisterClientScriptBlock(this, this.GetType(),
            "EditModalScript", sb.ToString(), false);
    }

现在，如果我不得不猜测ScriptManager.RegisterClientScriptBlock中的某个地方有问题，但我真的不能判断是否是这样，和/或应该做些什么来解决问题，因为我只了解c#。

有人能就问题出在哪里或如何解决给出一两个提示吗？
