    [CLOSED] Linked Comboboxes Mask

    There is a problem clearing the mask on linked comboboxes.

    Using your example: (examples2.ext.net/#/Form/ComboBox/Linked_ComboBoxes/) ... if you select Belgium the cities load fine and the mask clears. Then select Brazil. The cities also load fine but the mask does not clear.

    I was unable to reproduce.

    What browser do you test with?

    Problem occurs in ie9, Firefox and Chrome. You need to select a city each time (as well as a country) and you'll find the loading mask will not disappear on the city combobox after multiple selections.

    Though it's not reproducible with the latest Ext.NET v2 sources.

    It would be rather hard to provide you with a fix, because it's related to many things. Please wait the next release.

    Thanks for the update and happy to wait for the next Ext.Net release for the fix. You can close this thread.

    I've this issue too and i'm using Ext.Net v2.
    The problem occurs also with the linked comboboxes and when the loading of the linked combobox takes a little bit longer. Then the mask doesn't disappear.
    So it's only when i already click the trigger of the linked combobox when the loading is not finished yet.

    Kind Regards

    Hi @Birgit,

    Could you provide us with exact steps to reproduce? I was unable to reproduce it.

    Hi Daniil,

    I finally managed to produce an example. I think the cause is the autorender option i use:

    <%@ Page Language="VB" AutoEventWireup="false" Culture="auto" uiculture="auto" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <script runat="server">
            <DirectMethod()> _
            Public Sub LoadStore1()
            End Sub
            Protected Sub Store1_Read(ByVal Sender As Object, ByVal e As StoreReadDataEventArgs)
                Dim _Data As New System.Data.DataTable
                Dim _DataRow As System.Data.DataRow
                Dim _Index01 As Integer
                _Data.Columns.Add(New System.Data.DataColumn("ID", GetType(Integer)))
                _Data.Columns.Add(New System.Data.DataColumn("DisplayName", GetType(System.String)))
                For _Index01 = 0 To 10
                    _DataRow = _Data.NewRow()
                    _DataRow("ID") = _Index01
                    _DataRow("DisplayName") = String.Concat("DisplayName" & _Index01)
                Me.Store1.DataSource = _Data
            End Sub
        <form id="form1" runat="server">
            <ext:ResourceManager ID="ResourceManager1" runat="server" DirectMethodNamespace="ParentMethods" /> 
            <ext:Button ID="btnLoad" runat="server" Text="LoadStore">
                    <Click Handler="ParentMethods.LoadStore1();" />
            <ext:Window ID="Window1" runat="server" 
                Title="Gridpanel Mask" 
                    <ext:GridPanel ID="GridPanel1" runat="server" Height="400">
                            <ext:Store runat="server" ID="Store1" OnReadData="Store1_Read" AutoLoad="false" >
                                    <ext:Model runat="server" IDProperty="ID">
                                            <ext:ModelField Name="DisplayName" />
                                            <ext:ModelField Name="ID" />
                                <ext:Column ID="colDisplayName" runat="server" DataIndex="DisplayName" Text="DisplayName" Flex="1" />

    Thank you for the sample.

    Please use Hidden="true" instead of AutoRender="false".

    Or load the Store into a WIndow's AfterRender listener.

    Hi Daniil,

    Thanx! but are there no other possibilities? Because i use the autorender for performance issues. And i also want the store to be loaded before the window is shown.
