Do Not allow Add New Record if condition is fale

[Brian K]

I have a radgrid that its datasource takes three inputs before executing.  I also want to allow for inserts to take place, but those three dropdown selections must be made prior to allowing a user to insert a record.  How can I prevent the edit form for showing if the selections are not made prior to clicking the Add New Record buttion on the radgrid?

Hi Brian,

A command is fired each time a user interacts with the Grid. Be it paging, sorting, filtering or even editing. So when the user clicks on the Edit or Insert button, you capture the command event, and during that you can verify if all 3 options are selected as needed. If not, you can then cancel the command. In this case there will be a PostBack but nothing will change as the command was canceled.

You can check out the ItemCommand Event for more information.

Also, I recommend reviewing the Command Reference, Telerik RadGrid lifecycle, and Event sequence articles. These will help you get a better understanding on the topic.
