Client-side multi row select - detect last selection

[Marcel]

Hello,

I am using the client-side API and use AllowMultiRowSelection="True". I need to rebind a second control when a grid row is selected or deselected. My problem is that using the shift key or the checkbox at the top of the grid, many or all rows can be selected at once and each (correctly) fires the RowSelected event, causing many rebinds of the second control.

 

I only want to fire the rebind once per user action. Any suggestion is appreciated.

Hi Macrel,

There is no event that is called after the selection is complete, but you can use the code bellow to achieve it:

var lastSelected = null;
var extraSelected = true;
var timerStarted = false;

function timedCheck() {

  if (extraSelected) {
    extraSelected = false;
    setTimeout("timedCheck()", 25);
  }
  else {
    timerStarted = false;
    MyFunc(LastSelected);
  }
}

function MyFunc(lastSelectedIndex) {
  //Rebind your grid here
}

function RowSelected(sender, args) {
  LastSelected = args.get_itemIndexHierarchical();
  extraSelected = true;

  if (!timerStarted) {
    timerStarted = true;
    setTimeout("timedCheck()", 25);
  }
}
