Why there was any error saying "CheckedItems is not a member of Telerik.WebControls.RadComboBox" ?
Why there was an error saying "Checked is not a member of Telerik.WebControls.RadComboBoxItem" ?

Dim collection As IList(Of RadComboBoxItem) = rcb.CheckedItems
Dim intCheck As Integer = collection.Count

For Each itm As RadComboBoxItem In collection
If itm.Value = drName(strColumn) And Not (drName(strColumn) Is DBNull.Value) Then
itm.Checked = True
Exit For
End If
Next

my development tools were VS2010 using IIS 6.5 ASP 2.0

InvalidCastException on displaying RadGrid in designer

I've got a problem I don't know quite how to resolve; I've used Telerik AJAX controls on other parts of the site, but since I've upgraded to a newer version (Q3) and reregistered the reference, this error keeps popping up in the designer:

Error creating template groups. Reason: System.InvalidCastException: [A]Telerik.Web.UI.RadGrid cannot be cast to [B]Telerik.Web.UI.RadGrid. Type A originates from 'Telerik.Web.UI, Version=2009.3.1103.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4' in the context 'LoadNeither' at location 'c:\Users\klemens\AppData\Local\Microsoft\Visual Studio\9.0\ProjectAssemblies\gm17spra01\telerik.web.ui.dll'. Type B originates from 'Telerik.Web.UI, Version=2009.3.1103.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4' in the context 'LoadNeither' at location 'c:\Users\klemens\AppData\Local\Microsoft\Visual Studio\9.0\ProjectAssemblies\e9yumfmq01\Telerik.Web.UI.dll'.

at Telerik.Web.Design.RadGridDesigner.get_GridComponent()

at Telerik.Web.Design.RadGridDesigner.get_TemplateGroups()

Whenever I upgrade to a newer release of Telerik, I always uninstall the controls first, then install a newer version, but the version numbers in this case match, so I don't quite know how two different project assemblies got into the project in the first place.

[Solved] Multiple values ressources displayed on multiple columns in advanced form

in the Advanced form, whenever using the multiple ressources scenario (AllowMultipleValues = true), all the ressources are displayed in a single column (as shown in attached image).

This is OK if there is less than 3 or 4 possible ressources, but becomes pretty ugly whenever there is 10 or 15 potential ressources. Would it be possible to consider for a future release to add a parameter to display the ressources in several columns ?

Another possibility would be to display the ressources as a multiple selection combo or listbox (with checkboxes).

Keep uploading large files

Hi,

I'm just wondering if there is an opportunity to continue uploading large files even if you go to another page.
For instance, put the upload control on your master page, start uploading on one page and then go to another page, but see there the uploading progress.

Regards,
Al

Open the LightBox after Loading the page

Hi guys,

I need to obtain an url from the server side and introduce it in a audio tag that is inside the LightBox. I register a JavaScript block from the server side and I want to open the LightBox when the page load, I call my RegisterJSOpenLightBox method on ItemCommand event.

The problem is It works for many browsers but not with IE9. In IE9 when I try to open the lightbox with javascript (lightBoxPlayer2.show();) cannot find the lightbox. I try to register with $(document).ready but it doesn't work.
Do you have any idea? I also used cstext2.Append("$(function() {"); .This is the error SCRIPT5007: Unable to get property 'show' of undefined or null reference

Thank you very much

private void RegisterJSOpenLightBox(string urlFile)

{

Type cstype = this.GetType();

string csname = "OpenLightBox";

ClientScriptManager cs = Page.ClientScript;

if (!cs.IsClientScriptBlockRegistered(cstype, csname))

{

StringBuilder cstext2 = new StringBuilder();

cstext2.Append("<script type=\"text/javascript\">");

cstext2.Append("window.onload=function(e){");

//cstext2.Append("window.load=function(e){");

cstext2.Append("openLightboxPlayer('" + urlFile + "');");

cstext2.Append("}</script>");

cs.RegisterClientScriptBlock(cstype, "OpenLightBox", cstext2.ToString());

}

}




function openLightboxPlayer(url) {
    var player = document.getElementById("AudioPlayer");
    player.src = url ;
    player.preload = "auto";
    // var lightBoxPlayer = $find('<= LightBoxPlayer.ClientID %>');
    // lightBoxPlayer.show();
    var lightBoxPlayer2 = $find('LightBoxPlayer').show();
    lightBoxPlayer2.show();
    return false;
}

An invalid or illegal string was specified - how to understand where is the problem?

I see in FireBug the error:

Custom file upload dialog for file browsers

I'm very happy with the file browser dialogs themselves, but I'm not so thrilled with the file upload dialog used there.

Is it possible to use a custom made file upload dialog with the file browser dialogs?
And if so, how would I accomplish this?

GridDateTimeColumn Page Reload on enter

I have a gird on ap a web page and on the grid is a GridDateTimeColumn I allow filtering I have it set as

<telerik:GridDateTimeColumn DataField="TradeDate" DataFormatString="{0:MM/dd/yyyy}" DataType="System.DateTime" FilterControlAltText="Filter TradeDate column" HeaderText="Trade Date" ReadOnly="True" SortExpression="TradeDate" UniqueName="TradeDate" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" FilterControlWidth="110px" EnableRangeFiltering="true" AutoPostBackOnFilter="true" ShowFilterIcon="false">

</telerik:GridDateTimeColumn>

This works fine but for some reason if the textbox next to the date time picker has focus and I hit the enter key it reloads the entire page.

Tree node expand after browser back button click

Hello,

Background:
I'm using a RadTreeView within a custom module in DNN 7.

Problem:
When I click the browser's back button (probably in all browsers, but tested in Safari and Chrome with same results) and try to load nodes, I get a 500 err. The message is "Server.Transfer cannot be called in a Page callback." and the details are: "System.ApplicationException: Server.Transfer cannot be called in a Page callback." The stack trace is:

Has anyone ever seen this issue before?
