On client delete rowIndex not updated

[Nils C.]

Hi,

I am using a Radgrid with script services for the data binding.
For deleting a row, I implemented a GridClientDeleteColumn which fires a "Delete"-command on which I am deleting the clicked row via a script service. After deleting a row, the rowIndexes are actually not updated and I get some errors when I am deleting several rows after each other.

Here is my code:

   

function KontakthistorieGridCreated(ansprechpartnerid) {

    pms_neu.grid_service.get_history(window.location.hostname, ansprechpartnerid, kontakthistorieUpdateGrid);
 }

 function kontakthistorieUpdateGrid(result) {
     var tableView = $find("<%= rdg_historie.ClientID %>").get_masterTableView();
         tableView.set_dataSource(result);
         tableView.dataBind();
         tableView.set_virtualItemCount(result.length);
         adjust_pane_heights();
 }

 function OnCommand(sender, args) {
     //Die funktion kann ruhig leer sein, MUSS aber vorhanden sein (irgendwas mit Client-Object erstellen und so...)
     if (args.get_commandName() == "Delete") {
         var itemIndex = args.get_commandArgument();
         var history_id = sender.get_masterTableView().get_dataItems()[itemIndex].getDataKeyValue("id");
         pms_neu.grid_service.delete_history(window.location.hostname, history_id, history_delete_done);

         args.set_cancel(true);
     }
 }

There problem occurs because the commandArgument() isnot beeing updated after deleting the row and even not after I call the databind method again. Deleting itemIndex 0 will cause that the following first item has itemIndex 1 but it must be zero for fetching the right datatime.
 

var itemIndex = args.get_commandArgument();

var history_id = sender.get_masterTableView().get_dataItems()[itemIndex].getDataKeyValue("id");

Does anyone knows a solution for this?
I would really appreciate some help on this

Kind regards

Hello Nils,

Thank you for contacting us.

You could workaround this issue by iterating through the items and extracting their indexes. In the attachments you could find the project that uses this approach and extracts always the desired index.
