This question is once again related to the page I created and discussed here.

I noticed that if the page is inactive for a period of time, say, 10-15 minutes. and then I mouse over on the grid column to display tool tip, I get exception. 

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Exception occurs when I try to add control for tooltip using statement

e.UpdatePanel.ContentTemplateContainer.Controls.Add(ctrl)

Here is the Stack trace.


Note that I have about 10 columns in the grid, and about 8 columns are displaying tooltip. Each tooltip has different data but almost same structure of the controls to be added into tooltip. (They all use Table object which contains a RadGrid and some other controls maybe). 

   I noticed that this error occures on one or two columns, but not on all columns. If I try to display tooltip on other columns and then try back on the specific columns where it had above errors, it display them fine. I am not sure why?

   Do you think I can solve this issue by disabling ViewState on the page (or on some specific control)? Or if there is any other idea, please share.


   Thanks,

Hello,

I need to move the selected rows of one grid to another grid and vice versa. Since the data is more when i implement that in server side it is taking time . So i need to implement in client side. In web i come to know that how to select rows in client side and retrieve the values of selected rows. But i dont know how to move the selected rows to another grid . If any one can provide sample data that will be great help. I am attaching the screen on which i am working.

* As per standards of my project i should not use the List box and i should use only Grid


Thanks

Recently, I install the RadControl for ASP.Net AJAX Q2 in a Traditional Chinese version of Windows 7 x64 with Traditional Chinese version of Visual Studio 2010 Ultimate. When I open the document of RadControl for ASP.Net AJAX Q2, I see "Can't find requested content on your computer".

I open Microsoft Visual Studio 2010 Document directly, I only see the installed document but no RadControl for ASP.Net AJAX Q2.
I have set my Help Library to use local document.

Then I reinstall the computer with Traditional Chinese version of Windows 7 x64 and English version of Visual Studio 2010 Ultimate. And install RadControl for ASP.Net AJAX Q2 again. The document is fine in such environment. 

I reinstall the computer again with Traditional Chinese versions of Windows 7 x64 and Visual Studio 2010 Ultimate. I still can not see the Document of RadControl for ASP.Net AJAX Q2. The situation is the same as I mentioned above.

I think the document of the product may not work properly when using other language of Visual Studio 2010. Is there anyway to solve the problem?

Thank you.

I need to display datasource with alphatical nodes. For example, I have employee table instead of displaying hierarchy node, I need to display with alphatical nodes from A to Z with each node representing the alphabet. How can do it?

I have a page that has a radgrid and several children grids in tabs under that main grid.  Click a row on the master grid and all the child grids update. This is not the problem

Next I have and EDIT button at the top of the page. Clicking this spawns a RadWindow the contents of which is a seperate page which itself has 4 tabs. 1 of which contains a RadGrid.

So far my structure (in a psudocode kind of way) looks like this



When data was changed on this page I ran this javascript to refresh the parent page grids. This too worked perfectly.


Now to the issue.

As I mentioned there is a grid on the popup page in the 4th tab. The way this page is set up is that you select a row, and then click a common Edit button to edit that row. Clicking the Edit button opens yet another RadWindow with a form for adding/editing Addresses.

Now my phsuocode model of my windows and such looks like this.



I'll cut to the chase, When I click the save button on the Edit Address page, the javascript above does not refresh the Address grid on the EditLocation page. It does however do what it always did. That is, refresh the grids on the parent page (LocationPage).

Seems that this line

GetRadWindow().BrowserWindow.refreshGrid(args);

...is the one I need to change.

Just, what do I change it too? How to a get a grid in a rad window to refresh?

I want to make the up arrow decrease the value, and the down arrow increase the value for an integer numeric updown control.  How can I accomplish this?  To put this in context, the column is SortOrder and it is sorted ascending.....I want the up arrow to move the item up in the list by decreasing the value.  I am using a text box because I also want the user to be able to change the value manually.

Hi

I have a strange problem, and I suspect the answer will be blindingly obvious when I know what it is.. but here goes:

I have a panelbar with a customized version of the Black skin, following the the Telerik advice on this to produce a custom css.

All is well on my development machine, including the arrows to indicate sub menu items are available. The functionality and colours are exactly as planned.

After publishing to the remote site, all looks and works fine, except that the arrows do not appear, neither on mouse out nor mouse over. The only difference I can think of is that the local machine is IIS7.5 (win 7) while the remote server is IIS 6 (server 2008 R2).

ASP.NET v 4.0 is installed locally and remote  but the website is set up to use 3.5

Using Q3 2010 RAD controls.

Can anyone suggest where to look for the problem?

Thanks
