RadCombobox throwing exception in Safari Browser.

Hi,

We are using Q1 2007 version controls. We are getting problem with combo box in safari browser.

When we try to write some text in editable combo box, safari browser throws unhandled exception (xp, vista OS) and web application gets hanged. While,in Mac OS, browser gets closed for this same scenario.
Error message is: “Safari Web Browser has encountered a problem and needs to close” Also we are not able to track that where problem is occurring. For other browsers (IE 6/7, Fire fox), its working perfectly fine.

My combo box declaration is like this :

<

radC:RadComboBox ID="ddlUDC1" Skin="Default2006" Height="60px" runat="server" Width="200px" DropDownWidth="187px" meta:resourcekey="ddlUDC1Resource1" SkinsPath="~/RadControls/ComboBox/Skins" MarkFirstMatch="true" >

</radC:RadComboBox>

Please suggest solution for this.
Please note we want to continue with Q1 2007 version only. We do not want to upgrade it.

Any help on this will be appreciated.

Thanks,
Mittal

Create linked thumbnail from Image Manager?

Hi - I see references here in the forum to making image thumbnails, but I cannot for the life of me find a way to enable this functionality.

Here's what I want:

User hits the image manager button in the toolbar, gets the image manager dialog.
User chooses image
User either hits Image Editor button or some other "make thumbnail" button (doesn't matter to me)
Thumbnail is created
Image is placed as thumbnail with appropriate <a> tags to link to full-sized version

Step 5 is where I'm getting hung-up - I don't see any means of creating the link, short of hitting the link manager and manually entering the URL for the full-size image - that's too complicated for my end-users, I need an automatic or visual method. Seems like this is supposed to be a feature of the image manager. (At the very least, it should be.)

How do I do this?

Thank you!!

Missing thumbnail "Link to original"

In RadEditor 2009.1.1311 Image Manager doesn't contain the options "Link to original" and "Open original in new window" for thumbnails anymore.

Did you remove this feature? If so, what's the reason and will it get re-implemented soon?

Grid / Window Editing issue

I am attempting to recreate the demo Grid / Window Editing and have run into a problem on the protected sub:

Protected

Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As UI.AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest
I am receiving an "unknown type" error in reference to UI.AjaxRequestEventArgs
I have included all of the imports from the demo, but it seems like one may be missing?

Cannot change order of tab headers

The following tabstrip was created in the order of Notes, Contact Mechanisms, Relationships. Recently, we changed the order as shown below. The content in each tab is correct as per markup below. However, no matter which order I change the RadTab controls, the tab headers appear in the original order that each was created. Why is this happening and how can I fix it?

I put this markup on a new page and replace each RadMultiPage content with just a label ... it works fine. I thought maybe the code-behind was accessing some part of this control, so I changed the name of all IDs expecting to get a compilation error. However, as expected, the code-behind is not accessing any part of this control.

<asp:Panel ID="pnlTabStrip" runat="server" Visible="true">

<telerik:RadTabStrip ID="rtsContact" runat="server" SelectedIndex="0" MultiPageID="rmpContact" ReorderTabsOnSelect="true">

<Tabs>

<telerik:RadTab Text="Contact Mechanisms" />

<telerik:RadTab Text="Relationships"/>

<telerik:RadTab Text="Notes" />

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="rmpContact" runat="server" SelectedIndex="0">

<telerik:RadPageView ID="rpvMechanism" runat="server">

<uc1:WucContactMechanism ID="wucContactMechanism" runat="server" />

</telerik:RadPageView>

<telerik:RadPageView ID="rpvRelationships" runat="server">

<uc2:WucAssignedParties ID="wucAssignedParties" runat="server" />

</telerik:RadPageView>

Enable disable RadGrid columns depending of selected tab

Hi,

I want to hide columns in a RadGrid when the selected tab of a TaStrip, in another area of the page isn't the first (based on your wizzard code demo).

I have configured the ajax manager to do it, enabled the post back on the tabstrip and added the following event:

Protected

Sub RadTabStrip1_TabClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTabStripEventArgs) Handles RadTabStrip1.TabClick

If RadTabStrip1.SelectedTab.Text = "Compte Client" Then

RadGrid1.MasterTableView.GetColumn(

"Delete").Visible = True
RadGrid1.MasterTableView.GetColumn("Edit").Visible = True

Else

RadGrid1.MasterTableView.GetColumn(

"Delete").Visible = False
RadGrid1.MasterTableView.GetColumn("Edit").Visible = False

End If

End Sub

This code works at half in the sense of my column are not visible after any click on any tab (on the first "compte client" too) but they never come back Visible.

I also would like to know how I can modify this when I click on the "next" button of the wizzard example because only an user control is loaded in that case.

Thank you for your help,

Herve
