Dear All

I have created a small sample Application to get more knowledge using Syncfusion. But I am still fighting with them :-)

So I created a standard empty webform asp.net page with masterpage.

In my master page I do have set the Scriptmanger.

When I now test the Page it looks pretty good design wise, but if I press the next page button it crashed.

If I set in the web.config file this

<add key="LoadEJResourcesFromAssembly" value="false" />

The page loads, next page is working well, but the design is not taken.

Here is my MasterPage:

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="mainMaster.master.cs" Inherits="SYNC_Telephony.mainMaster" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Testing Syncfusion Grid</title>
    <asp:ContentPlaceHolder ID="head" runat="server">
        <link rel="stylesheet" runat="server" rel='nofollow' href="Content/master.css" type="text/css" />
    <form id="form1" runat="server">
        <asp:ScriptManager runat="server"> </asp:ScriptManager>
        <link rel="stylesheet" runat="server" rel='nofollow' href="Content/master.css" type="text/css" />
            <asp:Panel runat="server" ID="pnl" CssClass="panel">
                <asp:Label ID="lbl" runat="server" Text="Testing Syncfusion Grid" CssClass="label" Font-Bold="True" Font-Size="XX-Large" Font-Strikeout="False"></asp:Label>
        <div class="divMenuContainer" runat="server">
            <ul id="menu-bar">

                <li id="myaboutLink" runat="server"><a rel='nofollow' href="about.aspx">About</a></li>
                <li id="mycontactLink" runat="server"><a rel='nofollow' href="contact.aspx">Contact</a></li>
        <div class="pageContent">
            <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

               © 2016 by Martin for testig Syncfusion, v1.0
        <input type="hidden" id="hdnLoaded" name="hdnLoaded" runat="server" />

and this is my default page:

Hi Martin, 

Thanks for contacting Syncfusion support. 

We checked your sample and we were unable to reproduce the mentioned error when we moved to the next page. In our sample, when theLoadEJResourcesFromAssembly and EJResources  appsettings keys is set to true in the web.config file, the necessary stylesheets were added to the grid  
If we set as true, the necessary stylesheets will be added to the header section of the current page dynamically to render the EJ components. So, we do not need to refer to the externalStyle sheet of the grid.   

Query 2 : “<add key="LoadEJResourcesFromAssembly" value="false" /> 
The page loads, next page is working well, but the design is not taken” 

In your code example, we found that you have referred both ej.web.all.min.css and ej.widget.all.min.css in the application.  
To apply styles to the grid control, you have to refer to ej.widgets.core.min.css and ej.theme.min.css files. If you use ej.widgets.all.min.css, then you don’t need to use ej.widgets.core.min.css and ej.theme.min.css because ej.widgets.all.min.css is a combination of these two. The ej.web.all.min.css is also a combination of ej.widgets.core.min.css and ej.theme.min.css files. So, remove anyone of the reference from your application.   

If you still face the same issue we need the following details. 
1. Provide the stackrace of an issue. 
2. Provide screenshot of the issue. 
3. Reproduce the issue in the attached sample. 
Refer to the Help document of getting started.
