Hello

I have a simple RadGrid bind on EntityDataSource,

when i pass AllowSorting="True", the header bar becomes invisible, Is he missing something?

 

<asp:EntityDataSource ID="MyData" runat="server" ConnectionString="name=AGIDE4_DEVEntities"
    OnSelecting="MyData_Selecting" OnSelected="MyData_Selected"
    DefaultContainerName="AGIDE4_DEVEntities" AutoSort="False"
    EntitySetName="CompteConnexion_Profil_Parametres" EntityTypeFilter="CompteConnexion_Profil_Parametres"
    EnableUpdate="True" EnableDelete="False" EnableInsert="False">
</asp:EntityDataSource>
 
<telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" />
 
<telerik:RadAjaxPanel runat="server" LoadingPanelID="RadAjaxLoadingPanel1">
    <telerik:RadGrid ID="RadGrid1" runat="server" EnableHeaderContextMenu="true" DataSourceID="MyData"
        OnSelectedIndexChanged="RadGrid1_SelectedIndexChanged"
        OnPreRender="RadGrid1_PreRender" OnColumnCreated="RadGrid1_ColumnCreated"
        OnColumnsReorder="RadGrid1_ColumnsReorder" OnEditCommand="RadGrid1_EditCommand"      
        PageSize="100" VirtualItemCount="100" ClientSettings-AllowColumnHide="false"
        AutoGenerateHierarchy="false" AutoGenerateColumns="true" AllowPaging="true"  AllowSorting="False"
        AllowFilteringByColumn="true">   
        <ClientSettings
            Virtualization-RetrievedItemsPerRequest="500"
            Virtualization-EnableCurrentPageScrollOnly="false"
            Virtualization-EnableVirtualization="false"
            Virtualization-ItemsPerView="100"
            Virtualization-InitiallyCachedItemsCount="500"
            Scrolling-EnableVirtualScrollPaging="false"
            Scrolling-AllowScroll="true"
            Scrolling-UseStaticHeaders="true"
            ReorderColumnsOnClient="true"
            AllowColumnsReorder="true"
            Selecting-AllowRowSelect="true"           
            ColumnsReorderMethod="Reorder" />

Hi Laurent,

The behavior you describe seems rather strange. I used the RadGrid code you have provided to assemble a sample project. The headers were displayed and the sorting was working as expected on my end. Check out the video below as illustration:


Would you disable AJAX by setting the EnableAJAX property of RadAjaxPanel to False and see if the behavior changes. Also, while AJAX is disabled press F12 to open the browser console and check if there are any errors listed.

Nothing Change.

In attache files:

one file with AllowSorting=false

and another with AllowSorting=true

 

thie is a code of my page :

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="UC_RadGrid.ascx.cs"
    Inherits="Agide_4.Composants.Graphique.Grille.UC_RadGrid" %>
 
<telerik:RadPersistenceManager ID="RadPersistenceManager1" runat="server">
    <PersistenceSettings>
        <telerik:PersistenceSetting ControlID="RadGrid1" />
    </PersistenceSettings>
</telerik:RadPersistenceManager>
 
<asp:EntityDataSource ID="MyData" runat="server" ConnectionString="name=AGIDE4_DEVEntities"
    OnSelecting="MyData_Selecting" OnSelected="MyData_Selected"
    DefaultContainerName="AGIDE4_DEVEntities" AutoSort="False"
    EnableUpdate="True" EnableDelete="False" EnableInsert="False">
</asp:EntityDataSource>
 
<telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" />
 
<telerik:RadAjaxPanel  runat="server" EnableAJAX="false"  LoadingPanelID="RadAjaxLoadingPanel1">
    <telerik:RadGrid ID="RadGrid1" runat="server" EnableHeaderContextMenu="true" DataSourceID="MyData"
        OnSelectedIndexChanged="RadGrid1_SelectedIndexChanged"
        OnPreRender="RadGrid1_PreRender" OnColumnCreated="RadGrid1_ColumnCreated"
        OnColumnsReorder="RadGrid1_ColumnsReorder" OnEditCommand="RadGrid1_EditCommand"      
        PageSize="100" VirtualItemCount="100" ClientSettings-AllowColumnHide="false"
        AutoGenerateHierarchy="false" AutoGenerateColumns="true" AllowPaging="true"  AllowSorting="False"
        AllowFilteringByColumn="true"  AllowMultiRowSelection="false" OnItemDataBound="RadGrid1_ItemDataBound" OnItemCommand="RadGrid1_ItemCommand" >
        <MasterTableView AllowMultiColumnSorting="true">
                <PagerStyle AlwaysVisible="true" />
            </MasterTableView>
 
        <ClientSettings
            Virtualization-RetrievedItemsPerRequest="500"
            Virtualization-EnableCurrentPageScrollOnly="false"
            Virtualization-EnableVirtualization="false"
            Virtualization-ItemsPerView="100"
            Virtualization-InitiallyCachedItemsCount="500"
            Scrolling-EnableVirtualScrollPaging="false"
            Scrolling-AllowScroll="true"
            Scrolling-UseStaticHeaders="true"
            ReorderColumnsOnClient="true"
            AllowColumnsReorder="true"
            Selecting-AllowRowSelect="true"           
            ColumnsReorderMethod="Reorder"         
            />
 
    </telerik:RadGrid>
 
</telerik:RadAjaxPanel>
 
<telerik:RadButton runat="server" Visible="true" ID="SaveRadGridSetting" Text="Save grid" AutoPostBack="true" OnClick="SaveRadGridSetting_Click" />
<telerik:RadButton runat="server" ID="ExportRadGrid" Text="Export grid" AutoPostBack="true" OnClick="ExportRadGrid_Click" />

Hello Laurent,

I used the code you have provided and created a sample project. I used dummy data for testing.

The sample is working as expected on my end. Please download the attachment and give it a try. Let me know how it works on your end.

I would appreciate it if you describe what should be different in the sample in order to replicate the behavior you are observing.
