Can AllowColumnHide be set for individual columns?

I have a grid where most of the columns can be hidden by the user, but there are some that should always be visible. Is there a way to specify which columns in a grid can be hidden?

Dave.

Help with Portal Site

Hi Guys,

I am using Rad Dock Prometheus for the first time and I have an ambitious project.

I want to build a home page which initially loads lots of "widgets" into a certain layout, allow the user to move them around, save their layout to a database and add new widgets by clicking an add button.

The problem is that I don't know where to start. I have got several Widgets containing user controls and managed to put them into three docking zones. I can move them around on the page but don't know how to do the following....

* Save the layout to a SQL server database.
* Reload the layout when the user logs back on if they have a layout saved.
* Allow them to add new docks which are initially hidden

I have looked at the myportal example in the documentation but haven't managed to get the "save layout to session" code working at all. Does anyone know of a good article on how to make a portal like this ?

If you need any example of how it needs to work you can see what I mean on http://gamers.eurogamer.net/.

Thanks, Jon

[Solved] data from nested grid into dataset

I am updating an order form using the RadGrid nesting feature, but I'm having trouble getting the data from the nested grid and inserting it into a dataset so I can further process the order, inserting it into the database. I keep the "not set to an instance of an object" null reference error. Specifically, when I try to initiate the row count for the data in the nested grid in the codebehind. Here's the relevant aspx code;

    
            <telerik:RadGrid ID="rgPogList" runat="server" DataSourceID="dsListPogs" GridLines="None" AllowPaging="True">  
        
                <MasterTableView AutoGenerateColumns="False" DataKeyNames="StoreNum,POGID" DataSourceID="dsListPogs">

                    End If 
        
                End Sub

I am hoping a second set of eyes will help me resolve this. Basically, I will eventually take the dataset and creating a new order that will then be inserted into a database.

Dynamic PanelBar Height

Hi, How do I set the panel bar height to expand dynamicly... ie when we run the panel bar with all items open it currently extends beyond the total height of the panel bar, so you cant see the bottom panels... easily fixed by making the total panel bar height larger, however this will not look good when all items are not expanded... so we would like to set it that the height of the entire panel bar grow and shrink as per the total panel usage. ie making the total height of the container variable or flexible.
I hope this makes sense, thanks for any help.

Using RAD Editor in List items

I've downloaded the RADEditor Lite edition for MOSS.
I want to use the RADEditor as the default rich text editor for my list objects.
I've followed the instructions given in the installtion doc(chm file) for using RADEditor for list items. But I'm not getting the RADEditor as the default rich text editor. I've tried IISRESEY as well. But no luck..

Can you please let me know where have I gone wrong?

Thanks in advance.....

Add RadXMLHttpPanel to a webpart in wss3.0

Hi,
We are developing an asp.net WebPart that is integrated in Sharepoint site.
The WebPart contains telerik:RadXmlHttpPanel which will have a toggled display on the click of a RadTreeViewNode(ajaxified).
The WebPart project consists of code behind file only.
No .aspx file is there.
The problem is how will the XMLHttpPanel's serviceRequest method be executed.
From the examples available on http://demos.telerik.com/aspnet-ajax/xmlhttppanel/examples/default/defaultcs.aspx,
I have seen that a javascipt function is added to a RadScriptBlock in .aspx file. This function internally sends a call to
XmlHttpPanel_ServiceRequest function and then the corresponding controls are loaded with values. Please let me know how to execute serviceRequest function of RadXMLHttpPanel in my case.

With Regards,
Shikha

Very strange behavior when changing RadUpload visibility.

On my page, I have a RadUpload control (Q3 2009) which I use to submit images.

After the image has been uploaded (on postback), I hide the upload control and show a "change logo" button. If the user wants to change the image, they'd click on that button and I make the RadUpload control visible once more.

When I do this however, some very strange behavior occurs with the control - its seems like the underlying HTML File Input control is shown whenever the user mouse's over the RadUpload control..

Its hard to explain, so I made a little movie of the issue using Jing: http://screencast.com/t/MDE3ZTA4NG

Is there a known issue with the RadUpload (in IE 8) that causes this behavior on visibility change?
