DataTable as datasource
posted

I have made a site using the original GridView of asp.net 2, and i have the trouble that inside an UpdatePanel (i'm using Microsoft Ajax) the  add/update/delete operations are very slow even if i have attempted every optimization; but i have a dozen of grids inside the page, even if with a few records (and there are many editable fields)

In the online samples for WebDataGrid i'm seeing only ObjectDataSource as datasource for grids, while in my site i'm using an ADO.NET DataTable; so my questions , in order to download the Infragistic trial and try a conversion, are:

1) DataTable as source for the WebDataGrid

2) Is it possible to create a new row with clicking a button? i'm seeing only samples where the new row is already present

3) In a grid i have the first editable field as a DropDown, changing the selected index in other 2 fields i should activate 2 numeric fields (when the value of the first DropDown is "OTHER") or others 2 combos , dinamically filtered by the first dropdown SelectedValue (obviously except when the value of the first dropdown is "OTHER"); the DropDowns datasources are DataTables

4) numeric input: is it possible to avoid that the user write more digits than the expected picture: for example if i want that the user could enter only 2 integers and 2 decimals (max number allowed 99,99) is it possible to avoid that the user could write 999,999?

5) My site is using UpdatePanel and some other controls from Microsoft Ajax Toolkit: apart UpdatePanel, used exclusively for GridViews, the others controls does not have problems adding the Infragistic grid in the page? and i'm using Page Methods, will these continue to work ?
