Hi,

I ran the telerik upgrader from within visual studio, downloaded the latest version and upgraded. Afterwards, I go the following.

(The correct dll (2010.1.519.35) was copied to the bin folder).

Upgrade Log:

              </runtime> 
        
            </configuration>

From my own personal point of view, the upgrader is really of beta quality. It is NOT dependable.

My project was 99% complete and now I can't demo so much as a start page if the suits come calling. Not good.

Thanks,

Richard

[Solved] Grid Filter error, Syntax error: Missing operand after '["column"]' operator.

Hi I recently upgraded to Version=2010.1.519.40 afterwards we started getting this Grid Filtering error;
"Syntax error: Missing operand after '["column"]' operator."

We get a different error when filtering an INT column:
"The expression contrain undefined function call Convert.ToDecimal()."

Then to top it off when leaving the page we get a "null object" error but only when the grid is filter, sorted, or grouped by using the HeaderContextFilterMenu. If you turn this feature off and sort, filter, or group by the default method it doesn't throw this error.

I am not sure what changed but this is a deal breaker for us. We wil most likely have to roll back so any help would be greatly appreciated.
Thanks

RadGrid select and grouping feature not working on next rebind of RadGrid

Hi,

I have created a RadGrid (_grdDocuments) inside RadAjaxPanel. I just need to enable multi-row selection and grouping in that RadGrid so below are the codes I have used. Data of the RadGrid is gathered thru a dropdown value say (Company1, Company2, Company3).

Initially when data is loaded in the RadGrid, you can select a row or even group the grid based on the dragged column name.

Now when you change the value of the dropdown say Company 2, you cannot select or group in the Grid anymore. Why? Am I missing something here?

This is WSS 3.0 WebPart application. No client or server events attached.

I am using Telerik version 2008.3.1314.35

Thanks

I am trying to create a design document for a project which I plan on using RadControls in.

Does anyone have any examples of how they documented using some of the more complex RadControls like the RadGrid?

Thanks.

[Solved] Don't want to hightlight row

Hello.

Any way to not highlight the row when the checkboxes are enabled?

<telerik:RadListBox ID="lstSubject" runat="server" CheckBoxes="true" Height="250" Width="100%" />

Just want the checkboxes, but do not want the row to be "selected" when the user clicks one.

Determine if Page is loaded in RadWindow

Question: How can I determine at the server side, if the page is being rendered in a radWindow?

Background: I have a Master page with toolbar buttons. The child page is loaded in an iframe. The user can click a toolbar button which posts a message to the parent window where another child page is loaded in a radwindow.

Because all of these child pages can appear in the IFrame, they need the toolbar buttons that load other reference pages in a radwindow, but I don't want to provide this option if the page itself has been loaded in a radWindow.

Example:
The site has Pages A, B, and C. Each page dynamically tells the parent the toolbar buttons available based on the state of the data, user permission, etc. When viewing page A, users need the ability to quickly reference pages B and C. When viewing Page B, users need the ability to quickly reference pages A and C, and so on.

When a page is displayed in this dialog, I'd like to be able to remove the popup toolbar buttons so that the modal window cannot open up additional windows.

IE8 rendering problem

Hi,

We have a problem with the RAD editor in IE8. It seems to render totally wrong even when we add the compatibility mode meta tag:

In other browsers (tested in chrome 4 and FF 3.5) this problem never occurs. Also when I open the development tools in IE8 and switch manually to Browser mode: IE8 everything works fine. But on the initial page load, with or without the IE7 compatibility tag, it gives problems. See the attached screenshots for details.

We are using Telerik ASP.NET AJAX controls with buildnumber 2008.1.619.0.

I hope you can help me with this.

Thanks in advance!

Adding items dynamically

I have list of items.

Once user clicks on the item then I want to show details for these items.

I don’t want to load all item details on page load. How do I do this more efficiently.

For item details I have a user Control previously I have used Radpanel bar with list of items On page load I create all these PanelItems dynamically and add user Controls to each panel item.

Should I user Grid or Panel bar?

This time I want to load list of items on page load and dynamically load user control data when user clicks on particular item.

Can I do this? How will be view state handled if I do this on item click. If user clicks on first item I load data for that user control if user clicks on second item I will load data for that item ..what will happen to previously clicked items? On postback will it load all previously clicked items.

What’s the most efficient way to show item details with grid or Panel bar?

Thanks

PanelBar
