強制按鈕導致回發

Question

我有一個按鈕，它將導致創建一個彈出窗口：

<ItemTemplate>
        <asp:Button ID="viewHoursButton" runat="server" Text="View Hours" OnClick="viewHoursButton_OnClick" />
        <ajaxToolkit:ModalPopupExtender ID="viewHoursPopup" runat="server"
                TargetControlID="viewHoursButton"
                PopupControlID="viewHoursPanel"
                CancelControlID="closeInfoPanelButton2"
                DropShadow="true">
                </ajaxToolkit:ModalPopupExtender>
    <asp:Panel ID="viewHoursPanel" runat="server" CssClass="infoPanel">
           //content of panel including gridview
    </asp:Panel>
</ItemTemplate>

彈出的面板具有gridview，並且在按下按鈕時會傳遞一個SQL參數。 ：

protected void viewHoursButton_OnClick(object sender, EventArgs e)
{
    Button btn = sender as Button;
    GridViewRow row = btn.NamingContainer as GridViewRow;
    SqlDataSource6.SelectParameters["nonScrumStoryId"].DefaultValue = storyGridView.DataKeys[row.RowIndex].Values[0].ToString();
    var viewHoursGridView = storyGridView.FindControl("viewHoursGridView") as GridView;
    if (viewHoursGridView != null)
    {
        viewHoursGridView.DataBind();
    }
}

問題是因為沒有回發到服務器，所以無法顯示gridview。 當向ajaxToolkit：ModalPopupExtender添加按鈕時，將發生回發。 我該如何找回？

嗨，我使用此代碼Javascript關閉彈出窗口並刷新父Web表單

    Dim str_java As String = "<script language='javascript'>"
    str_java += (" window.onunload = refreshParent; ")
    str_java += (" function refreshParent() { ")
    str_java += (" window.self.location.reload(true); } ")
    str_java += (" window.close(); ")
    str_java += ("</script>")

    ScriptManager.RegisterStartupScript(Me, GetType(Page), "cerrarpagina", str_java, False)

這可以幫助你

您可以通過將__doPostBack附加到事件來使用Javascript強制回發。

function doClick(sender, e) { 
__doPostBack(sender,e); 
}
