Question

问一个关于ext.net TreePanel控件的问题

TreePanel放在DropDownField中，现在想实现如下功能。当Assign WareHouse（第一级父仓库）值发生改变时，WarehousePosition的tree则应该变成对应的子仓库。问题，现在就是不知道要怎么去实现相关功能。

Answer 1

//获取GridPanel中dropdownfiled下的treePanel控件的值
var getWarehouseValue = function (el,node) { // Warehouse dropdownlist selecting method, edit by Annie
if (node.leaf!=true) {
Ext.Msg.confirm("",hdPleaseSelectWarehouseLast.getValue(),function (btn) {
if (btn == "yes") {
el.dropDownField.setValue(node.id,node.text,true);
hdPid.setValue(node.id); if(!el.dropDownField.grid.record.modifyJsonObject){
el.dropDownField.grid.record.modifyJsonObject = {};
}
el.dropDownField.grid.record.modifyJsonObject.WarehouseId = node.id;
el.dropDownField.grid.record.modifyJsonObject.WareHouseName = node.text;
//el.dropDownField.grid.record.data.WarehouseId = node.id;
el.dropDownField.grid.record.data.WareHouseName = node.text;
}
}, this);
}else{
el.dropDownField.setValue(node.id,node.text,true);
hdPid.setValue(node.id); if(!el.dropDownField.grid.record.modifyJsonObject){
el.dropDownField.grid.record.modifyJsonObject = {};
}
el.dropDownField.grid.record.modifyJsonObject.WarehouseId = node.id;
el.dropDownField.grid.record.modifyJsonObject.WareHouseName = node.text;
//el.dropDownField.grid.record.data.WarehouseId = node.id;
el.dropDownField.grid.record.data.WareHouseName = node.text;
}
};
