RadGrid1.SelectedValue

[Nyceane]

Is this fixed yet?  because selectedvalue will still give me a null no matter what I do.

Hi Nyceane,

You could access the selected items by its table like follows:
grid.get_masterTableView().get_selectedItems()
Our developers will review the issue as soon as possible.

Happy Holidays!

'Telerik.WebControls.RadGrid' does not contain a definition for 'get_masterTableView'

How do I exactly get the selected value?

Hello Nyceane,

Detailed information about the changes made in the client-side API of RadGrid you can find in these online resources:

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/Overview/DefaultCS.aspx (section Client-side API and events)

http://www.telerik.com/help/radcontrols/prometheus/ (chapter Controls -> RadGrid -> Client-side API reference)

More precisely, to extract the selected value client-side you can use the client key/values exposed through the API as shown here:

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/Client/Keys/DefaultCS.aspx

Server-side you can access directly the <RadGridInstance>.SelectedValue property by invoking its ToString() method for example.

is this going to be fixed on next update?

Nyceane, I do not find anything broken at the moment that has to be fixed . Telerik team provided several options to fetch the selected value on client, use one of them to do that.

there are no example showing how to retrieve key value off the table, the only example they are showing is how many rows are selected.  if you have a good way to retrieve client select value, please show me, i'd be highly appreciated

I have used the RadControls Grid for displaying items for years. I use an ASP.NET FormView to edit the data.  On the RadGrid's onSelectedIndexChanged SERVER SIDE event to grab the <RadGridInstance>.SelectedValue.ToString() value to databind my FormView (which is working fine).  However, when I go to update the FormView using the RadGrid  SelectedValue.ToString() value, it is NULL.  I don't know how or why, but this value should persist until you clear the selected indexes or databind the grid.  

I feel this is a bug in the Prometheus Grid.

Hello Anthony,

Can you please submit an example which illustrates the unexpected behavior? Furthermore, can you please check whether the same approach works for the MS GridView control and its SelectedValue property?

Hi Anthony,

Just a quick follow up.

I have reviewed your code and I notice that you are calling DataBind() for the grid on every Page_Load. This will clear the grid child controls and ViewState and will recreated the controls according the the specified data source however the ViewState of the control will be lost. You can check this using standard MS GridView and you will get same result.

All the best,

You are missing out with the setting of DataKey for the grid. If we set the DataKeyName, SelectedValue works properly..

Thanks,
