Bug (?): editor.fire("MediaManager", {}); fails

Currently we are working on a new project. With the new RadRibbonBar (using v.2011.1.315.40) - which is very nice - we decide to try to implement a RibbonBar for the RadEditor. Basically we are rewiring all the calls to the RadEditor using the javascript fire() method just as in the example at the demo site.

Sofar this was working perfectly. However when doing:

editor.fire("MediaManager");

we will get the javascript error:

"Runtime-fout Microsoft JScript: Sys.ArgumentNullException: Dialog Parameters for the MediaManager dialog do not exist
Parameter name: dialogName"

A trace on the editor javascript object showed that

editor._dialogOpener._dialogDefinitions.MediaManager

Is expected but does not exists. (See attachment) For all to other dialogs like 'LinkManager' or 'TableWizard' it the DialogDefinitions are set.

---

To overcome this problem we tried to create a work-arround:

var ImageManagerDefinitions = editor._dialogOpener._dialogDefinitions.ImageManager;

var MediaManagerDefinitions = objectCloner(ImageManagerDefinitions)

MediaManagerDefinitions.Title = "Media Manager";

editor._dialogOpener._dialogDefinitions.MediaManager = MediaManagerDefinitions;

However this is not the full solution.. Because the ImageManager is now loaded. To make the work-arround functional de SerizalizedParameter of the Media Manager is required. Sofar we didn't find out how to get this Parameter.

Hope you can fix this bug and tell us how to get that SerizalizedParameter or tell us that we are doing something realy wrong here...

How to prevent automatic filter from Column filters

Hi,

I am using a RadGrid with Column filtering enabled.
What i would like to achieve is to Apply all RadGrid column filters at once with a button_click, and somehow disable the automatic refresh for every single column.

I was thinking i could disable the refresh that is getting triggered after setting a column filter, but was unable to do so.

Any help would be appreciated!
Thanks!

RadTextBox not giving text

Hi all,
I've got a problem with radtextbox in my page. If I use javascript to insert text in a RadTextBox I can do it easily and it works well, but if I try to access thata text server-side, radtextbox.text property is ALWAYS empty, even if I type into it, not only if I set it using Javascript.

My text box is defined as follow
<telerik:RadTextBox TextMode="MultiLine" runat="server" ID="txtNote" MaxLength="512" Rows="5" Width="100%" />

Kind regards
Riccardo

Install into GAC on Server 2008 r2?

Hi,

I have been unsuccessful in my attempts to install Telerik.Web.ui.dll into the GAC on our Win 2008 server r2. I have tried everything from drag drop to windows\assembly (doesn't show an error, doesn't install) to gacutil from 2.0 sdk (error with telerik assy being greater than current assembly) to gacutil 4.0 from VS 2010 tools. I am running my sites under .NET 4.0 and have set all application pools to use .NET 4.0.

Is there any way to do this other than placing the telerik.web.ui.dll in each bin folder for each app?

Thanks!

Using a ValidationSummar in a RadToolTip

Hello,
I would like to use a RadToolTip to add, modify items from a RadGrid.
It works well but when I add to the radtooltip a RequiredFieldValidator and ValidationSummary, the radtooltip doesn't work.

Could you help me ?

Here are the javascript an HTML:

<

telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

function

CloseToolTip()

{

var tooltip = Telerik.Web.UI.RadToolTip.getCurrent();

if(tooltip)

{ tooltip.hide(); };

}

function

OkToolTip()

{

CloseToolTip();

ajaxManager.ajaxRequest(

"RT_LOT");

}

</

script>

</

telerik:RadCodeBlock>

<

telerik:RadToolTip ID="RT_LOT" runat="server" HideEvent="FromCode" Modal="True"

Position="Center" RelativeTo="BrowserWindow" ShowCallout="False">

<br />

<tr>

<td><asp:Label ID="RT_LOT_LibLabel" runat="server"></asp:Label></td>
<td><asp:RequiredFieldValidator ID="RT_LOT_RFV" runat="server" Display="Dynamic" ErrorMessage="Erreur"

ControlToValidate="RT_LOT_Lib" SetFocusOnError="True">*</asp:RequiredFieldValidator></td>

</tr>

<tr>

</tr>

<tr>

<td><input id="RT_LOT_Ok" runat="server" type="button" value="Ok" onclick="OkToolTip();"

style="width: 80px; color: #008000; font-weight: bold;" /></td>

<td><input id="RT_LOT_AnnBt" type="button" value="Annuler" onclick="CloseToolTip();"

style="width: 80px; color: #FF0000; font-weight: bold;" /></td>

</tr>

</table>

</telerik:RadToolTip>

Here is the code behind:
// Ajaxifying

protected

void Page_Load(object sender, EventArgs e)

{

try

{

radAjaxManager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(manager_AjaxRequest);

radAjaxManager.AjaxSettings.AddAjaxSetting(toolBar, RT_LOT);
}

catch (Exception err)

{...

}

// open the RadToolTip from a toolbar:

protected

void toolBar_ButtonClick(object sender, RadToolBarEventArgs e)

{

try

{

switch (e.Item.Value)

{

case @"CRT":
...

RT_LOT.Show();

break;

}

catch (Exception err)

{...

}

}
// get the data from the RadToolTip

protected

void manager_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)

{

try

{

if (e.Argument == @"RT_LOT")

{

... };

}

catch (Exception err)

{ ...

}

Many thanks...

People consitently pick on every expand link just to see no data associated with it, can this be changed to be hidden. And is ther a way to change the picture of the expand link to a plus sign instead of an arrow.

Passing Extra Parameters to Web Method from ClientSettings DataBinding

Is it possible to pass parameters other than row index, max rows, filter, and sort to the Web Method? I can't seem to find any examples. I have a RadGrid successfully using a Web Service to do client-side data binding, but I need it to pass in some extra parameters.

I'm thinking that I *might* be able to do this by passing the other parameters as part of the filter parameters and then handling that in the Web Service, but that just seems like a hack. :-)
