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.

[Solved] Collapse/Expand Images

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.

When I try to filter a column in my RadGrid it comes back empty (no rows)

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

Disable navigation via Navigation Bar

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:

Dim __Wizard As RadWizard = sender

Try

Select Case e.CurrentStepIndex

Case o_Step_Company.Index

Me._Validate_Companies()

Case o_Step_DateFilter.Index

Me._Validate_Dates()

End Select

Catch vx As ValidationException

vx.CreateNotification()

__Wizard.ActiveStepIndex = e.CurrentStepIndex

Catch ex As System.Exception

ex.SaveToDatabase()

ex.CreateNotification()

End Try

Thanks,

S. REISINGER

[Solved] Getting Started Info

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?

Partial Ajax call without triggering page load

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.

Chooser change is not refreshing background

Greetings,

How do I get the chooser to change everything on the page? Right now, I change the skin and the controls are restyled, but I have to refresh with F5 to get the background to change. Is there some kind of cache setting I need to change?

Thank you!
