RadGrid OnNeedDataSource problem

[Mark]

Hi Telerik, 

I posted a thread a couple of days ago and I thought I had solved my problem but turns out I just moved it.

My problem now is that I have template columns that contain buttons and others that have text that needs to be on a different color depending on the status of the item.

So basically, I used to bind my grid using the 'simple way' (Create data table, add source to the grid and bind)
Once it was bound, I would go through each rows, set the text to the button and set the appropriate CSS on the text label. 

Since I needed to sort and to filter, I saw that I could use the 'OnNeedDataSource' event, which is the second way to bind a grid.

This worked and I could sort/filter my grid.

But now, after the event is called, I tried to change the CSS and the text again but it says that the grid doesnt have any items.

I believe its because it wasnt bound (even though I can see the rows once everything is done)

Once again, I found the answer myself after looking at the available methods on the gridview.
If you want to change values on specific rows (in my case the text/style according to the row's content), you have to do them in the method OnDataBound. It would really be useful to add this to your documentation because it only says you need OnNeedDataBind and thats it, which isnt the case.

Hello Mark,

For this requirement it is a better idea to use the item specific event handlers provided by RadGrid:

You can also check the following article:

Hope this helps.

Okay, I'll take a look at this but as I replied earlier, OnDataBound worked too, the only thing is that since it wasnt linked to a specific item, I had to go through all of them, which is pretty much equivalent to calling ItemDataBound each time ?

Hi Mark,

Basically yes, however, the ItemDataBound event is raised nevertheless and it is specially designed for such cases.
