WebGrid控件树的点击一个节点同时选中父节点和子节点 －－ Intersoft WebUI Studio.NET 2007控件使用

1.在WebGrid控件中这样设置可以把数据已树状形式显示

2下面是相应的JS代码

//选中子节点
  function DoChildCheck(rootTable,CurrentRowElement,check,strFunc)
  ...{
        var selectedIndex = CurrentRowElement.rowIndex; 
        var selectedSrLevelAttributes = CurrentRowElement.attributes["srLevel"]; 
        var selectedSrLevel = parseInt(selectedSrLevelAttributes.value);
        var tableElement = CurrentRowElement.parentElement;
        for (var i = selectedIndex + 1 ; i < tableElement.childNodes.length ; i++)
        ...{
            var rowElement = tableElement.childNodes[i];
            var srLevelAttributes = rowElement.attributes["srLevel"]; 
            var srLevel = parseInt(srLevelAttributes.value);
            if (selectedSrLevel + 1 == srLevel)
            ...{
                var row = rootTable.ToRowObject(rowElement);
                doCheck = false;
                if (check)
                    row.Check();
                else
                    row.Uncheck();
                doCheck = true;
                strFunc = strFunc + GetRowCode(row,2) + ',';
                strFunc = DoChildCheck(rootTable,rowElement,check,strFunc);
            }
            else
                break;
        }     
        return strFunc;        
  }
  //选中父节点
  function DoParentCheck(rootTable,CurrentRowElement,check,strFunc)
  ...{
        var selectedIndex = CurrentRowElement.rowIndex;
        var selectedSrLevelAttributes = CurrentRowElement.attributes["srLevel"]; // get self reference level                    
        var selectedSrLevel = parseInt(selectedSrLevelAttributes.value);                                
            
        var tableElement = CurrentRowElement.parentElement; // get table element that holds self reference rows
        
        for (var i = selectedIndex ; i >= 0 ; i--)
        ...{
            var rowElement = tableElement.childNodes[i];
            var srLevelAttributes = rowElement.attributes["srLevel"]; // get self reference level                       
            var srLevel = parseInt(srLevelAttributes.value);
            
            if (selectedSrLevel - 1 == srLevel) // check the level of self reference level
                                                // if true = parent row
            ...{
                var row = rootTable.ToRowObject(rowElement);
                doCheck = false;
                if (check)
                    row.Check();
                else
                    row.Uncheck();
                doCheck = true;
                strFunc = strFunc + GetRowCode(row,2) + ',';
                strFunc = DoParentCheck(rootTable,rowElement,check,strFunc);
                break;
            } 
        }
        return strFunc;
  }
