Gridview which events to use

[Geoff]

I do not normally work on the desktop and I am really struggling with the grid view.

I have a number of basic maintenace forms that have a grid on them. I thought I would see if I code manage with the add, update an delet buttons by using the grids bulit in functions but I cannot get my head round which way I should be going.

 

I have an ubound grid which I am loading from a list of custom objects. I am loading it unbound so I can use the built in drag drop to re order the items.

I am handling the delete in RowsChanging so I can validate the process and cancel if required, this seems to work but if this is not good please advise?

I was trying to to deal with the add and update in RowsChanging and Rows Changed but I have run into all sort of issues so I guess this is the wrong approach.

If anyone some guidance on this I would be very grateful.

Thanks

Goff

DOH! Please disregard this, I was thinking about it all wrong!

I have now figured it out and it works a treat.

Hi Geoff,

Thank you for writing.

Suitable places to perform the validation before adding and deleting rows are the UserAddingRow and UserDeletingRow events. Additional information is available in the following documentation resources:

• http://docs.telerik.com/devtools/winforms/gridview/rows/new-row#user-events
• http://docs.telerik.com/devtools/winforms/gridview/editors/data-validation
  

I hope this helps. Should you have further questions please do not hesitate to write back.
