Postback on mouse drag selection

[David Cowan]

I need to perform a postback on drag selection.  I currently use

OnMouseUp="GridMouseUp(this, event)" on the RadGrid element to call

function GridMouseUp(sender, e) {
    setTimeout(function () {
        var grid = $find(window.gridId);
        if (grid != null && grid.get_masterTableView().get_selectedItems().length > 0) {
            __doPostBack(window.gridUniqueId);
        }
    }, 0);
}

This works for the drag select case but also does postbacks when clicking on the filter textboxes which I do not want.  Is there any way in client code to detect OnMouseUp of a Drag select action?

Hi,

 You can check the target element of the DOM event and if it is a table row (or cell) then the mouse up has happened on a grid item and should cause a postback. Here is a sample code

var e = e ? e : window.event;
var target = e.srcElement ? e.srcElement : e.target;
if (target.tagName.toLowerCase()=="td" && target.parentElement.id)
{
        //mouseup on a grid item - do postback
}

All the best,
