RadScheduler calendar navigation not working

Hi All,
I have simple calendar with Entity Framework data source. In design, all plays nicely but not after deployment:
- I cannot navigate between Month and Week, nor the popup calendar will work
- I cannot edit an appointment in advanced mode (edit in advanced mode is set to true)

any advice would be helpful.

Hierachy RadGrid giving error Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.

Hi,
I am using Hierachy Rad Grid and for editing the record I am using InPlace Editing mode.

When I have Parent Item and child item of some ther node in Edit mode and click on the update button it is giving me the error

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Secondly I am not able to have the hierachy grid where in only one row should be editable.

Please help it is urgent.

Kind Regards
Vishal Gupta

CustomPaging and DetailTables

I'm evaluating RadGrid as a possible replacement for custom grid work that we have been doing. We essentially want to use a few features at the same time but it seems that CustomPaging and DetailTables are not compatible. I keep getting "This method is supported only for pager mode NumericPages Source" errors. Is it possible to have CustomPaging and DetailTables at the same time? If I use NumericPages, detail works. When I hook in our custom paging dropdown, detail no longer works but custom paging works. I hope I'm just missing something!

Thanks!

Hi,

I have a Rad Window which opens when a button is clicked.
While the page is loading, I want to display a loading image, to notify that something is happening.

Is there a way to display RadAjaxLoadingPanel every time a new rad window is being opened?

RadPane Scrollbar Display Issues

Hello,

I have a RadSplitter with two RadPanes, the left pane contains a RadTabStrip and RadMultiPage objects, with RadGrids inside the RadPageViews. The splitter is set to scroll vertically, but when a grid nested view is expanded (causing the content of the pane to be larger than its height), the pane is resized to allow scrolling but the scrollbar does not appear. White space appears in its place instead. However, when I mouse over another part of the page, the scrollbar magically appears. I also noted that when I collapsed the nested view, the existing scrollbar still remains as disabled until I mouse over another part of the page. Then it disappears.

I've attached some screenshots to help illustrate my issue.

Initial.jpg - How the page looks before expanding the second item
AfterExpand.jpg - After expanding the second item. Note how the content is now too large and gets cut off at the bottom of the left pane. Also note the width of the content of the pane has been narrowed slightly and now shows a white space where the vertical scrollbar should be.
AfterMouseOver.jpg - After moving the cursor away from the splitter, note the scrollbar now displays as expected. No postback has occurred. (Alternatively, the scrollbar also shows after using keystroke Ctrl + A to select all of the content on the page.)
AfterCollapse.jpg - After collapsing the second item. Note how the scrollbar remains but disabled (since there is nothing to scroll). Also note how the content of the left pane is hidden behind the scrollbar. The expected result here would be that the scrollbar should disappear since there is no more scrolling.
AfterMouseOver2.jpg - After moving the cursor away from the splitter, note the scrollbar has now disappeared, as expected. Again, no postback has occurred.

Here is an example of the markup I've used. I removed the markup from the other tabs and from the right RadPane for brevity:

Am I missing something in my markup? Or could it possibly be a bug in the control or maybe even IE? I am running IE 9.0.8112.16421

Circular Reference Not Allowed - After Telerik Version Upgrade

I am trying to upgrade the telerik version in an older project. After I use the upgrade wizard I start to get endless "Circular Reference Not Allowed" errors. I have looked around for solutions and seem to have corrected some issues by changing .ascx controls to different folders, as suggested online. But as soon as I fix one circular reference another appears. I am sure the this releated to the wizard upgrade because I have reverted to older copy, tried upgrading again, always getting the same results after upgrade. Can anyone give me suggestions?

Thanks

How can I get the x-axis label when bound to a database

Hello,

I have a radchart which is bound to a database. When I click on a piece of the bar chart, I want to drill down to another chart based on the label of the piece they clicked. For instance, if I have a bar chart with the number sold of apples/oranges on it, when I click on the apples colomn, I want to show another chart about apples. How can I determine what the label is from the click method. The args.seriesItem.name is "Item2", so that doesn't help. Also, args.seriesItem.label.base.TextBlock.text is empty.

Thanks,

Eric

Scrolling and Header issue

Hello,

I've a question about the RadGrid, scrolling and headers. I've defined a RadGrid with none StaticHeader because I want my customers to drag and drop the columns to create their own preferred view (column order). The grid is scrollable, scrollheight is set to 197px, which means in my case a viewport of 7 record/lines. When scrolling I want to 'freeze' the header row, at this moment the header scroll's with the lines so it scrolls out of the viewport.
I've read several articles on the web and the solution is : use static headers. As a mentioned before, that is not an options because I want the user to decided which column order het wants to use (with drag and drop).
On the web I found an article where they do something with CSS on a normal GridView to force the header in the viewport (http://forums.asp.net/t/1162406.aspx) but that solution does not work for the RadGrid.

Hopefullty there's someone with a solotion for this issue.

Regards,
Jos
