Hello Mark,

For DateTime scenario, please try not to use string. GetValueData() only can be used for DateTime object in this scenario. This happens because you use Format Date in this scenario.

e.g

If you assign the Date object in WebInput1 such as :

            var currentTime = new Date();
            currentTime.getDate();
            el.SetValueData(currentTime, true);

When you use GetValueData(), it will show the value.

Hello Mark,

The method needs additional parameters (boolean).

E.g

                    el.SetValueData(txt.value, true);

It should work. Hope this helps.

Hello,

WebGrid hierarchical only can be created with ISDataSource or bind via dataset. However, if you want to use another way such as Unbound way, I am afraid you could not do this for your scenario.
Unbound is designed just for viewing the data. It is not designed for insert, update and delete.
You try to look for our WebGrid unbound (without hierarchical). If you do any flypostback request such as refresh,sorting or filtering, it will raise an error.

Hello,

You can use enable caching at the page level, by setting the EnableCaching to true.
The page still needs to be created for the first time. But subsequently, it will load from cache, so it'll be faster.

E.g
MainPage>>UXFrame
UXPage1>>NavigationCacheMode="Enabled" (at page level)
