hello,

I have a radComboBox with Checkboxes enabled. I use the OnItemChecked and OnCheckAllItems events while loading data to Combobox with ItemRequested event and LoadOnDemand enabled.

the problem is that the OnItemChecked and OnCheckAllItems events not working.

How can I make it

Is there any way to cancel the material design ripple at runtime?

I'm using the material design theme with the RadPanelBar and in each item I've added a star icon to toggle favorited items. The problem is that even though I am able to cancel/prevent the item click from occurring, the ripple still happens.

My click event is bound to the icon toggle element directly with jquery, but calling stopImmediatePropagation and all other event cancelling methods I know of do not work for preventing the ripple effect from firing.

Thanks,

Adam

I haven't touched my application in some time.   This is a C# Asp.net web app using Telerik Ajax controls. I've just updated to the latest controls and I'm having a problem adding a new RadComboBox.

Up till now I have not had this problem.  Whenever I added a box it's label would always be in line on the left.

With this new box, no matter what I do, the label is always above the dropdown. 

This is within a div that has a width of 100% of the current page.

What could I be forgetting?

Hi,

I managed to get RadGantt tasks inserts and deletes working fine. But for some strange reason 
UI changes(e.g. Add Child tasks, rename task, change dates...etc.) to the tasks are not being saved.
Am I missing something obvious?

I'm using latest  UI for ASP.NET AJAX version 2017.1.116.40

Below is my declarative

I have an auto-generated grid from a datatable.  I need to find the index of 2 columns and then traverse the columns (i.e. col 4-6) and then grab the data from each cell and make it bold based on a condition. 

1 -How can I get the indexes of these if I know the header name?

2 - how do I traverse the columns and grab it's data?

Thanks in advance!

I am testing out the Telerik RadGrid to see if it can replace a custom Silverlight grid we have in our product.  The problem is that our product reads the data from CouchDB as a JSON file which we de-serialize into a class (stored in a Session variable) that contains collections (System.Collections.Generic.List) of other classes.  I bind one of these sub-collections to the RadGrid.DataSource, depending on what I need to display and call RadGrid.DataBind().

Everything there works fine, except when I go to update the InPlace grid values with the RadGrid_UpdateCommand event.  I only get the old values and not the updated ones, possibly due to the PostBack resetting the values. I have found other postings of people with this issue, but they are all binding to a DataSource object like SqlDataSource.

Is it possible to update a collection bound to the RadGrid datasource?
