AddNewRecord button No Postback in batch mode

[Mark]

My Radgrid is in EditMode="Batch" . When I click on the AddNewRecord I need to create a record in the DB. The ItemCommand event does not fire. 

 

Is there a way to get it to fire.

Is there a better way to do it so the batch mode stays intact?

Hi Mark,

BatchEdit is a Client-Side (JavaScript-based) editing functionality of RadGrid. Everything you do (create rows, delete, update) happens on the client. The only Server-Side event that is fired is the batcheditcommand, when you click on "Save Changes", see https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/server-side-programming/events/batcheditcommand

To interact with the BatchEdit manager, you can take advantage of the Batch Editing Client-side API - https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-editing/edit-mode/batch-editing/client-side-api

You can find more specific information about the BatchEdit functionality in the following article: RadGrid Batch Editing Templates and Specifics -  https://docs.telerik.com/devtools/aspnet-ajax/knowledge-base/grid-batch-editing-templates-and-specifics

If you rather prefer to work on the Server-Side with the Grid, you can use any EditMode except Batch.

Here is an InPlace EditMode example that you might like: Update all, individual or selected rows using RadGrid with InPlace edit mode - https://docs.telerik.com/devtools/aspnet-ajax/knowledge-base/grid-update-all-individual-or-selected-rows-using-inplace-edit-mode

So how would a wire into the addNewRecord event from the Batch Editing Client-side API methods?

If you want to subscribe to the event that will trigger when clicking on "Add New Record" in BatchEdit mode, you will need to use the OnBatchEditOpened event:

• https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/client-side-programming/events/onbatcheditopened 

In the event handler, a newly created row will have a negative row index in its ID attribute since it does not exist in the database. You can use that information and set up a condition that will check for the ID ending with -1, to distinguish the Add New Record Vs. editing an existing row.

function OnBatchEditOpened(sender, args) {
    var editedRowElement = args.get_row();

    if (editedRowElement.id.endsWith("-1")) {
        // Creating a New Row
    } else {
        // Editing an existing Row
    }
}

That did the trick. Thanks!

 

  function OnBatchEditOpened(sender, args) {
                var editedRowElement = args.get_row();
                if (editedRowElement.id.endsWith("-1")) {
                    PageMethods.AddRow();
                    var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
                    masterTable.rebind();
                } else {
                    // Editing an existing Row
                }
            }
