//删除多行
function deleteRows()
{
//if(b[0]==null)
//{
//alert('null')
//}
var b=new Array();
b=ShowSelection();
var grid = ISGetObject("WebGrid1");
var i=0;
var maxRow=b.length;//待删除的行数量
var updateProcess = setInterval (function ()
   { if (!grid.IsInProgress && i < maxRow)
   {

var rows = grid.RootTable.GetCheckedRows();
var row = grid.RootTable.ToRowObject(rows[i])
   row .Delete();
    i++;
}
    if (i >= maxRow)

    {
     clearInterval(updateProcess);
    updateProcess = null;
    } }, 1);

I can delete several rows by js Code
//获取选择的N行
function ShowSelection()
        {
      var grid = ISGetObject("WebGrid1");
      var rows = grid.RootTable.GetCheckedRows();
      var arr=new Array();
while(rows.length!=0)
{
for (var i=0;i<rows.length; i++)
                {
                    var row = grid.RootTable.ToRowObject(rows[i]);
                    arr[i]=String(row.KeyValue);//行的主键值
                }
return arr; break;

}
if(rows.length==0)
{alert('至少选择两行！');
return arr;
   }

}

Hello,

As default, You could not delete several rows. You can only delete one by one. However, you can delete several rows at the same time, if you use BatchUpdate feature. You can select which rows that you wanted to be deleted. When you finished, you can accept the changes.

Regards,
Handy
