I am cross-posting in Grid and Ajax forums due to not know which forum would be most appropriate.

I've created my page following this example:
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/clienteditbatchupdates/defaultcs.aspx

In this demo the grid row's unique ids are the first column called Product ID which is displayed in the gird. For my application each row's unique id is a GUID which I do NOT want displayed. If I set the visibility of this column to false the ajax does not work because it does not have a unqiue id to pass to the code-behind functions. If I set the visibility to true all works.  From this example it appears I must display the unique id column for the code to work.

How can I not display the GUID but still make it available to the ajax functions to pass to the code-behind file functions?

We are trying to reduce the grid ViewState using a PageStatePersister and database.
Everything is working fine also using the advanced data-binding except for the exporting functionality (xls, pdf or csv) does not matter the format.

The exported file is correct, we ignore the paging and the whole data is saved correctly, but if we click for example on the pager, the RadGrid loses the paging and also the excel button on the command items, this happens only if we have already exported a file.

The same code without the PageStatePersister works fine.

We can't figure out where the error is, do you have any clues?

After doing about a day of searching around the web, these forums, and co-workers that have done similar applications as the one I'm currently tasked with, I'm forced to start a thread for help.

My issue: I'm using the Telerik DynamicRadGrid control in a DynamicData 4.0 web application and am able to use [Display(Order=-1)] in order to position my ForeignKey columns for a specific table at in a specific order in the INSERT and EDIT templates, but the ordering is not reflected in the DynamicRadGrid column ordering. I need to move a column from the far right (end) of the column listing in my DynamicRadGrid to the far left (start) of the column listing in my DynamicRadGrid control.

The DynamicRadGrid control in my DynamicData PageTemplate ListDetails.aspx file:


The control is populated via the Page_Init() in the code behind:

The [Display(Order=-1)] code is found in my PartialModelClasses Class and actually works when viewing/editing a specific record on an individual basis and not in the DynamicRadGrid control, which leads me to believe that the issue lies in support of the feature in the Telerik control and not in my code.

Any thoughts, ideas, or input would be greatly appreciated.

Hi Telerik,

How to disable "previous & first page" arrow buttons on page 1 and "next & last page" arrows when on last page?
Also disabling all arrows when row count is less than the page size?

Appreciate your help. Thanks!

I'm trying to use RadDatePicker in Visual Web Part. The problem was when I tried to call it in .vb (let's say its ID is radDate1), it did not exist in IntelliSense. Seeming like it's not recognized. 

TestWebPart.ascx

..

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

        <telerik:RadDatePicker ID="radDate1" Runat="server" AutoPostBack="false">                           

            <DateInput DateFormat="MM/dd/yyyy" />                   

        </telerik:RadDatePicker>

I have a dll project in that added the following methods to create RadGrid dynamically

this method will be called inside a ascx control to build the grid
If I use Telerik.Web.UI.dll 2012.2.607.40 version ItemCommand evant firing for InitInsert, PerformInsert, Update and Delete
But If I use Telerik.Web.UI, Version=2011.1.519.40 it is not firing all the events Only InitInsert is working
How to Solve this.

Could any one help to solve this issue.

Thanks in advance

Hi,

I have updated my existing application with rad controls- radcombobox, radlistbox etc, everything was working just fine but as soon as we launched our application in production the radcontrols stopped working. We disabled our state server and everything started working again but without state server our customers are facing log out /time out issues
The javascript error on the page is as below.

After looking into the details, looks like some control is affecting the state. Could someone please suggest something if they had faced similar kind of  issue.

Thanks,
Ruby

Hi

I cut and past from my webpages.  Multipage, panelbar controls causes the background color to be picked up with the text.  How can make it so that when I copy text the text format picked up but the background color.  If I put the same html in the space where the radpanel is then the background background color is not picked up but the text format is.  However, as soon as I put text in the radpanel or multipage then the text format and the background is picked up.  I have set the radpanel as transparent.

Is this a css solution 

Code Sample 

<telerik:RadComboBox ID="RadComboBox1" runat="server" Filter="Contains" EnableVirtualScrolling="false"
            EmptyMessage="Please type Here" AllowCustomText="true" EnableLoadOnDemand="false"
            MarkFirstMatch="true">
            <Items>
                <telerik:RadComboBoxItem Text="1" />
                <telerik:RadComboBoxItem Text="2" />
                <telerik:RadComboBoxItem Text="3" />
                <telerik:RadComboBoxItem Text="8" />
                <telerik:RadComboBoxItem Text="9" />
                <telerik:RadComboBoxItem Text="18" />
                <telerik:RadComboBoxItem Text="19" />
                <telerik:RadComboBoxItem Text="38" />
                <telerik:RadComboBoxItem Text="39" />
                <telerik:RadComboBoxItem Text="ABCD-39" />
                <telerik:RadComboBoxItem Text="ABCD-40" />
            </Items>
        </telerik:RadComboBox>

Problem

When I type number 9 in the above ComboBox, filter is not working.I tried with Chrome, its working fine.
I hope the problem is with IE7.

Please help me to fix it.

Thanks and Regards,
Manoj Kumar

Hi,

I have a RadGrid on my page that contains a NestedViewTemplate containing a RadPanelBar.  I have my HierarchyLoadMode set to ServerOnDemand.  What I would like to do is when the user clicks to expand a row, I want the RadPanelBar to list a set of sub-records of row I am clicking on.  I need the RadPanelBar to contain some aspet controls, so I am using the ContentTemplate.  What I have done is, in the DetailTableDataBind function, I am querying a database for my subrecords and binding the results to the RadPanelBar for that particular GridDataItem being passed into the function.  For each row of my sub-table, I am dynamically creating my ContentTemplate from a class I created based on another post on the Telerik site.  Below is the code for this.  In additional, in my Page_Load function I am looping through the RadGrid and creating the custom template again.  Everything I have done appears to work fine with one exception.  When I first open a detail row, the RadPanelBar in that row does not have the collapse/expand ability in the header.  If I open up a second row, the first row's collapse/expand then appears and everything looks great.  But of course the second row's collapse/expand isn't visible.  So I'm always one off from this working without issue :)  I've tried using the OnInit function to do what I am doing in the Page_Load, but whenever I do anything with the RadGrid in this function, opening the nestedview causes the entire grid to disappear from the page (almost looks like it lost it's data bindings).  I have a hunch that the 'OnDetailTableDataBind' is part of my issue, I am guessing I should be doing what I am doing there somewhere else since technically I don't need to even set the e.DetailTableView.DataSource for this to work.  Does anyone have any ideas where I might be off?  My two functions are below. 

Thanks for any suggestions!
Richard
