My platform: asp.net V. 2.0 EO-DataGrid
I have a WebMethod which will return a data set to the client using the ASP.NET AJAX ScriptManager.
Now I need to bind the Grid with the new data on the client side. It is possible to render and redraw the EO-DataGrid with the new data?

Hi,
You won't be able to do that. The Grid supports Callback mode for you to perform such updates, which is similar but is done through server event, not web method.
Thanks!

You mean the ICallbackEventHandler Interface?
What about the presentation of the datagrid after refresheing the content?
The datagrid has a fixed number of lines after rendering in code behind.
It may be that the number of rows in the DataGrid changes after Callback; then the presentation can be changed?
Thanks!

No. This is what I meant (look for Callback Mode): http://doc.essentialobjects.com/library/1/grid/mode.aspxThanks

Another question in this connexion:
Is there the possibility to change the size of the datagrid on the client via javascript after rendering the Grid via codebehind? I have found in the client API no evidence.
Something like this does not seem to run:
var grid = eo_GetObject("Grid1");
grid.style.height=275; ->'style' is NULL or no object
I suspect that it is not implemented. Is there another way?
Thanks!

Hi, I believe you can do: grid.setSize(w, h); eo_GetObject returns a JavaScript object, not a DHTML element. So it doesn't have style property. See here for what methods the Grid object has: http://doc.essentialobjects.com/library/1/jsdoc.public.grid.aspxThanks

works fine!
how to address other attributes (for example ScrollBars = "Auto" or no ScrollBars) per javascript?
In 'jsdoc.public.grid.aspx' I have found no evidence to.
Thanks!

You can not. That's why the document is useful for you. It tells you what is available and what is not available.
Thanks
