Hi Guys

I have used the Property Grid to present all the information about a 'record' that is stored in a Database.

It's very nice and the customer likes it. Especially the part where we can define the <Description so the user gets to see a description of the parameter they are looking at.

e.g

<Description(

"The number the Customer was ringing from"), _

Category(

"Contact Details")> _

Public

Property A_Nummer() As String

However they now want multiple language support and I am struggling with how to handle difference languages for the property Desciption and Category Attributes. If I use any other than a fixed description , I get an error stating 'Constant Expression Required'

At present I am looking at having to create separate classes for each language and loading a different class dependant on the langauge the user wants. I already have different classes dependant on what type of record the user selects to view, so then I need each of those in a different langauge that can be selected ( Yuk)

It would be far easier to use the translate function I currently use to load the description text!

Any ideas?

Many thanks

Rob

Update, I have gone though the events looking for something that may allow me to reformat the text that is being displayed.. but havent worked out anything..

Column width in detailsview

Hi Telerik,

I have a listview with a view type of detailsview which is data bound within the code and displays 4 columns (auto generated).

In the attached image is there a way to set columns 2,3 & 4 width to the longest field value and first column to a max of the remaining listview width thus removing the white space to the right?

Many thanks.

Steve.
