Hi,

I'm populating a Gallery from a datasource in code behind. However, in some instance we want to put a static image before the retrieved results (eg. If there is a special offer on an item, the special offer image should be the first image in the gallery before the images from the datasource start the slideshow)

Can anyone please help with this? I am struggling to both insert a static item from code behind and then ensure it is the first image in the slideshow.

Regards

Dale

Font Substitution in RadEditor

For web users who don't have the fonts that I've specified in RadEditor, I'd like to be able to specify substitute fonts, like you can with font-family in CSS. Does RadEditor support this?

RadGrid filter expression not working with ODataSource

Hi,

I've an implementation of RadGrid, source for which is OData.I am getting error when I apply the "Contains" filter. I found that the filter expression generated by the radgrid is not resolved by the OData and I get the following error.
The expression (([1].ColumnName1 = 1234) And IIF(([1].ColumnName2 = null), "", [1].ColumnName2).Contains("abc")) is not supported.

This issue started occurring after I updated the RadGrid dll from version 2012.1.215.35 to version 2014.2.618.35.

In the old version the filter expression used to be:
ColumnName1 = 1234 &&(ColumnName2.Contains("abc"))
Whereas with the new dll this expression is generated as:
ColumnName1 = 1234 && (iif(ColumnName2== null,"", ColumnName2).Contains("abc"))

Please help as soon as possible.

Thanks

RadFilter losing values inside filter expressions

Hello forum... long time reader, first time poster.

I do have a support ticket open on this issue, but we seem to be stuck. I thought I'd ask the forum community if anyone had any ideas.

Short version... I am updating a RadFilter in a server side callback. Immediately after updating it, the client side filter values and the grid it is filtering look great. I have a button for refreshing the grid. The first time the user hits that button after the filter is set, the filter is hosed. By hosed, I mean that the right expressions/etc are there, but their value is 0 (or Nothing depending on the type). I do have the need for manipulating the sql string that the filter produces, so I am using a RadFilterSqlQueryProvider in my callbacks. Another thing to note, it happens whether EnabledAJAX is true or false.

In working with the support ticket, I was able to reduce the problem to a pretty small example. I would LOVE it if some Telerik guru could tell me what I'm doing wrong or if there is a better way to do it. I have been stuck on this for 3 weeks. ;(
