Hi,

I have an ImageEditor which I would one to allow user to draw on the image and save it as a new image.
But with my below code, once I click on the pencil, it seems like the pencil is not working as I am unable to draw.
I only have code on the aspx page as I do not know what code to put in aspx.cs page as the demo did not put any code.
Can anyone help and let me know how can I do the above using ImageEditor?

Thank you

NullReferenceException using RadFilter in Page_Load

Hi, I have a RadFilter that I am trying to add an expression to on the form load. The idea is that when someone clicks a hyperlink on a different page, they are redirected to a different page and the radfilter is set up for them with the data they clicked (in this specific case, it would Select Amends and put in the appropriate value.

I just want to mention that this code works exactly how I need it to when It is inside of a button click event on the page that gets redirected to.

The following is called in my page_load:

pnlSearch.Visible = False
pnlAdvanced.Visible = True

Dim amendsByExpression = New RadFilterContainsFilterExpression("Amends")
amendsByExpression.Value = Session("Search_Text")
rfAdvancedSearch.RootGroup.AddExpression(amendsByExpression)
rfAdvancedSearch.FireApplyCommand()

Why does the code above work when its encapsulated inside of a linkbutton click event, but not in the page load? How can I make it work in the Page Load?

Is there a way to move the drop down arrow in a RadGrid GridBoundColumn from the first position to the last position in the row? I don't even see where that is generated in the RadGrid code.

Here is the code

How to remove 1 sec delay in Donut Chart transition animation upon binding client JSON data?

I am making an SVG map with mouseover on provinces showing reports and visualized data. One of it was a Donut Chart, this is not a big deal of data we're loading so I think this is not the cause and the overall experience is not laggy so I think it is by design by Telerik for it to have 1 sec delay before load transition animation. I need to display the donut chart faster without delay because of the nature of my project without turning off the transition animation. Is it possible?

Hi,

We've used default skin, we've requirement to change its default arrow image with search image. Currently same classes are applied on all comboboxes when we change arrow image class than these changes are affected on all comboboxes. We need to change arrow image only in one combobox by using its default skin. How we change that like showing in attached snapshot? Any example would be appreciated.

Thanks
