Hi

This isn't specifically for the Telerik guys, rather the community. Does anyone have any ideas how I would query the database to find either recurring events, or rooms that don't have events, when taking into consideration recurring events?

Hi

I've created a completely standard, empty web project in VS 2012 / 2013 - and the 2013 version doesnt allow me to see the png sprites and style sheets that _should_ be served by WebResource.axd. The Telerik.Web.UI.WebResource.axd requests seem to work just fine. 

In both projects I've referenced the Bin45 versions of Telerik.Web.UI.dll and Telerik.Web.UI.Skins.dll, located in the "dependencies" folder, but deleted to save file size in the upload.

In the 2013 version I have removed a reference to System.Core (probably irrelevant) and I have aligned the minor differences between the two project's web.config files. None of the changes I made caused any differences whatsoever.

I'm attaching screenshots of the 2012/2013 differences.

This is a copy of a support ticket I created, I'll post an answer here if I get one before the forum manages to fix the problem :o)

Here is the web.config that works in 2012, but not in 2013

The GridTest.aspx file

And the GridTest.aspx.cs

Hi Team
We have defined a custom button column which is inherited from GridButtonColumn. On page load we can see the column and button in it. As soon as it gets data from an Ajax call. Data is populated into the grid but it clears all the contents in the custom button cell.This option is working fine in version 2013.3.1114.35 . As soon as I migrated to version 2014.3.1024.35 this problem popped up. Please help us to solve the issue.
I investigated and found that there is some change in the telerik populating the data into the cell.

In the previous version (i.e. 2013) cell is populating the data based on grid.data.ColumnType =="GridButtonColumn" so even if we inherited column from GridButtonColumn we manage to set the required ColumnType of masterTableView to GridButtonColumn on client side so that telerik grid databinding method behave as expected and displays button column.

But In new version even though we checked that columntype is set to GridButtonColumn in masterTableView button column data is cleared while binding data. We are not sure how to bring the same behaviour so that we can get the button column working because in new version (i.e. 2014 Q3) data bind internally calls "populateCell" method which gives a call to a function which is fired based on column type I think (i.e. a.Grid.GridBoundColumn or a.Grid.GridButtonColumn etc.)

We have implemented the following code while inheriting the GridButtonColumn .

i.e.

public override GridColumn Clone()

{

    RequiredGridBoundColumn requiredGridBoundColumn = new RequiredGridBoundColumn();

    requiredGridBoundColumn.CopyBaseProperties(this);

    return requiredGridBoundColumn;

}

I'm trying to load a grid control with data from a stored procedure using entity framework and I'm getting the following error: " The ObjectContext instance has been disposed and can no longer be used for operations that require a connection".    I had been using the commented out code below, which works, but wanted to use Entity Framework to call the stored procedure.  I've tried the code with and without the databind() without any difference.  the code for one of the stored procedures.  I have several other calls to stored proc's, which are called to Entity Framework that work fine, but they return distinct data values.  Any help appreciated.

Hi Telerik Team ,

I have been trying hard to save the data in Radgrid as word, excel, pdf formats.
I am successful in doing that using the radgrid - Exporting method.
But along with save, it also exports due to which we get the popup asking to save or open the file.
We can use Response.Redirect(Request.UrlReferrer.ToString()) to prevent the popup. But it doesnot seem handy in my situation.

My question is is there any workaround. Can I try it using telerik report viewer object ?
Can we make the use of report viewer exporting functionality to achieve what I need to ?
Any solution to my problem would be appreciated.

Thanks in advance ,
Anurag

Anyone else get this warning in dev console for chrome 39

The specified value '11/24/2014' does not conform to the required format, 'yyyy-MM-dd'.

Also, the chart labels are now not aligned. This was never an issue in chrome 38.

See screenshot below.

I am using ASP:TabContainer with ASP:Panel and ran into problem with refresh.  I could not refresh just the tab, only the only page - I really need just a tab refresh. 

So, I though I would tryRadTabStrip.

<%@ Register Src="~/Admin/GroupBasics.ascx" TagName="GroupBasicsCS" TagPrefix="uc" %>
<%@ Register Src="~/Admin/GroupForm.ascx" TagName="GroupFormCS" TagPrefix="uc" %>
<%@ Register Src="~/Admin/GroupMemberPage.ascx" TagName="GroupMembersPageCS" TagPrefix="uc" %>
<%@ Register Src="~/Admin/GroupMembers.ascx" TagName="GroupMembersCS" TagPrefix="uc" %>
...

    <telerik:RadTabStrip ID="GroupTabStrip" runat="server" OnClientTabSelecting="" AutoPostBack="false"  r Align="Justify" MultiPageID="GroupTabPV" SelectedIndex="0">
            <Tabs>
                <telerik:RadTab PageViewID="GroupBasicsPV"   Text="Group Basics"></telerik:RadTab>
                <telerik:RadTab PageViewID="GroupFormPV" Text="Group Form"></telerik:RadTab>
                <telerik:RadTab PageViewID="GroupMembersPagePV" Text="Group Members Page"></telerik:RadTab>
                <telerik:RadTab PageViewID="GroupMembersPV" Text="Group Members"></telerik:RadTab>
            </Tabs>
    </telerik:RadTabStrip>
      <telerik:RadMultiPage runat="server" ID="GroupTabPV" SelectedIndex="0">
            <telerik:RadPageView runat="server" ID="GroupBasicsPV">
                GroupBasicsPV
                <div class="contentWrapper">
                    <uc:GroupBasicsCS runat="server" ID="GroupBasicsCS" />
                </div>
            </telerik:RadPageView>
            <telerik:RadPageView runat="server" ID="GroupFormPV">
                GroupFormPV
                <div class="contentWrapper">
                    <uc:GroupFormCS runat="server" ID="GroupFormCS" />
                </div>
            </telerik:RadPageView>
 
            <telerik:RadPageView runat="server" ID="GroupMembersPagePV">
                GroupMembersPagePV
                <div class="contentWrapper">
                    <uc:GroupMembersPageCS runat="server" ID="GroupMembersPageCS" />
                </div>
            </telerik:RadPageView>

            <telerik:RadPageView runat="server" ID="GroupMembersPV">
                GroupMembersPV
                <div class="contentWrapper">
                    <uc:GroupMembersCS runat="server" ID="GroupMembersCS"/>
                </div>
            </telerik:RadPageView>
       </telerik:RadMultiPage>

With this setup if I try to open a RadEditor in the window I get a document not defined error:

Type.registerNamespace("Telerik.Web.UI.Editor");
Uncaught TypeError: Cannot read property 'document' of null 
in some Telerik code:
(function(a,b,c){b.RestorePoint=function(e,d){this.Window=e;
this.Document=e.document;
this.container=(d)?d:this.Document.body;

AND

when a do a refresh it not only refreshes the whole page, but it also changes the tab back to the first one.  It is also annoying that all the pages in the tabs are called on page creation before their tabs are clicked, potentially a huge waste of resources. 

There is might be a way to work around all this but the examples and documentation completely lack using an ascx collection. I would have thought a rather normal use.  I am probably doing it all wrong but I could only find one example with ascx's, TabStrip - Render Selected Page Only .  I probably need to control the tab strip more directly which I would pursue but the Document not defined error kind of kills using the TabStrip at all.
