Hello all,

I am using the Update Commant Item to perform an in-place edit. The data is successfully saved in the database etc. - but the grid data doesn't refresh automatically once the user clicks "Update" although the database reflects the change. I spent a day trying to figure this out but I am at a loss. Any help would be appreciated. I am pasting my code snippets.

All the columns are generated real-time so one doesn't see any column fields in the ASPX.

Thanks
Bala

Hello,

Try removing the line for the explicit grid rebind and see if it makes any difference. Note that the grid is implicitly rebound after update. If you want to rebind it implicitly, then you will need to cancel the default command (e.Canceled = true;).

if (strMessage.Contains(iChannelConstants.SUCCESS))
                {                    
                    e.Canceled = false;
                }
                else
                    e.Canceled = true;

Hello,

I changed it to the above. - still doesn't reflect the change in the grid.

Thanks

Hello,

If you cancel the command, you need to rebind the grid. So you can either cancel the command and rebind or not to call any of them:

if (strMessage.Contains(iChannelConstants.SUCCESS)) 
{                     
    e.Canceled = false;
else
     e.Canceled = true;
       RadGrid outerGrid = editedItem.OwnerTableView.OwnerGrid;
       outerGrid.Rebind();
}


Kind regards,

Hello,

I tried both and these are my results

1 - e.Canceled = false;
The change isn't reflected. The grid goes back to read-only mode (like the way it was before)

2 - e.Canceled = true + rebind
The change isn't reflected and the grid stays in edit mode.

Does the update call the Needdatasource event?

Thanks
Bala

Thanks all - I was able to resolve this. I was using old data on the Needdatasource event which is why it wasn't working.

Thanks once again.
