aspxgridview的客户端事件

<ClientSideEvents SelectionChanged="function(s, e) {OnGridSelectionChanged();}" />

----js---

function OnGridSelectionChanged() {
    grid.GetSelectedFieldValues('Customer_ID', OnGridSelectionComplete);
    }
    function OnGridSelectionComplete(values) {
    for(var i = 0; i < values.length-1; i ++) {
    grid.SelectRowsByKey(values[i],false);
    }    
    }
