Hi,
Working on a large application, and hit a problem with a RadAjaxLoadingPanel not showing.
The form in question follows a similar structure to a number of others on the site. In terms of logic, there are a number of panels (some with nested panels) that form a "wizard" type interface to allow users to make a credit card payment.
Due to the complexity of possible permutations of what controls could be updated by what, I've wrapped a AjaxPanel around it with a loading panel.
But the loading panel never shows.
If I remove the AjaxPanel and use an AjaxManager instead, the loading panel did initially show. However as I added more and more events to the AjaxManager, I got in to a number of problems which seem to relate to a cyclic relationship between some of the updated controls.
So I've gone back to the AjaxPanel, but with no loading panel. Any ideas?? :)

In my grid, i want to use editform when adding a new record and inform when edit a record.
I have tried it like this:
If TypeOf e.Item Is IGridInsertItem Then
RadGrid1 .MasterTableView .EditMode = GridEditMode.EditForms
else
RadGrid1.MasterTableView.EditMode = GridEditMode.InPlace
End If
If i try to add a new record it does not Work, a Little Wheel is just turning around and around
When i try to edit it Works ok, and show INplace edit.

RadScheduler.ExportSettings has access to change the PDF producer, I'm not seeing that property in the ClientExportManager, can you tell me how I can access that property?

Hi,
I am currently having a problem with clientchanges from a RadTreeView appearing on the server.
This was working fine still recently and after rolling back to known working versions I am still have the problem. I am using trackchanges on the node click event and I check the changes log before calling the trackchanges again so I can maintain a collection of changes to allow users to create a hierarchy of nodes before having to postback i.e.
var treeView = $find(treeViewClientId);
if (treeView._log._logEntries.length == 0) {
treeView.trackChanges();
}
As I mentioned this has worked perfectly previously. As I debug through the javascript I can see the entries and then when I choose commitchanges then I see the entries converted to JSON. However on postback I cannot see any changes coming through on the server.
Could you please give me some guidance on troubleshooting to check where these changes maybe getting lost?
Many thanks
Justin

I have a combobox that is filled with a list of preset values. In the codebehind, I determine the selectedIndex value through a lookup which returns a value of 0 to ~. If the value cannot be found the codebehind function returns -1.
Setting the selectedIndex to -1 merely selects the item at index 0 and this creates a problem for users who may save the data not knowing that the value was not found in the predefined list.
So, what I would like to do is set the text of the combobox to the value that was not found, or if the search string was initially empty, set the text to "Select Item", however, this doesn't seem to be working.
To make matters more complicated, I don't want to allow users to enter custom text because the idea is to get the users to select from the predefined values.
If I add another item at index 0, then the library we are using to manage the lists will not work.
How can I add a message similar to the EmptyMessage value, except this value would be as a prompt to select an item or the incorrect item itself that I can validate on postback.

I've got a grid that has EnableEmbeddedSkins=False because I'm trying to get it match the existing website's style using the CssClass property.
My grid has master and detail info, but I can't seem to figure out how to get the expand/collapse images to show up. When I hover over where they should be, I can expand/collapse the child records, but all I get is an outline where the image should be.
I defined the ExpandCollapseColumn-ExpandImageUrl and the CollapseImageUrl for the MasterTableView, but this isn't working. Where else do I need to define those images so that they show up?
Again, I don't have a custom skin, I'm just defining a few needed styles.
Thanks.

I can't seem to find any examples of how to filter Rad Grid rows using the built-in filters. I have the filters setup but they empty my grid. I just want to be able to perform simple filters on all rows. Any help would be appreciated.
Thanks

Good afternoon !
Is there an easy way to disable the navigation inside the RadWizards Navigation Bar ?
Reason:
I would like to validate the RadWizardSteps during an Ajax PostBack when the NextButtonClick event is fired.
The EventArgs during the ActiveStepChanged event do not provide CurrentStepIndex or other information of the WizardEventArgs
Code:
Thanks,
S. REISINGER

Hello,
I have the need to build a customer complaint portal. I want my users to be able to create a new complaint, and upload the most common file types as attachments. Such s jpg, doc, pdf, etc. I'm not sure how to attach those documents to the new record.
I understand how to upload the documents using AsyncUpload to a common directory.
How do you link the documents back to a particular record? Do you store the file path in a database somewhere? Do you create a new folder for each record and store that in a database? I'm missing a piece to the puzzle.
What is the easiest way, best practice, to accomplish this so users can view and manage images associated with a record?

Is there a telerik feature where you can do ajax without hitting the page load method of the code behind?
I am using a RadDataPager with next and previous options, when i click on either it goes through the code behind and executes the code in the page load. I don't want it executing the code in the page load.
I am use the RadAjaxManager.
