You can use the following trick.
Initially set the data type to : clientSide – i.e. – datatype: clientSide – the grid is loaded and nothing more, since the grid expect local data.
If some conditions are changed you can do:
….
jQuery(“#mygrid”).setDataType(“xml”); // or json
jQuery(“#mygrid”).setUrl(url);
…
jQuery(“#mygrid”).trigger(“reloadGrid”);
…

It is really difficult to me to understand what you try to do.
What is happen when you make this call?
Is the data loaded?

Maybe you should set a page too – something like
…
jQuery(“#griddata”).setPage(1l);
…

Please explain what is happen?
If you use FF you can look what is the returned data from server

Hi Andre,

At the moment this is not possible, but I hope that at the near future this can be achieved. It will be difficult to realize this since the data in grid is represented via table.

Hi,

You can look here

Section Data Types

Sorry there are errors that should be corrected

Currently dynamically change of the model is not supported.
One possible solution is to hide and show columns by condition, but not to change the model

Not sure but I notice that you call checksave twice one for save and second when edit. The error come from on edit and not on save. To work this i think one possible solution is:

onSelectRow: function(id){
if(id && id!==lastsel){
jQuery('#rowpain').saveRow(lastsel,checksave);
jQuery('#rowpain').editRow(id,true);
lastsel=id;
}
}


I.e call it only once when you save the row

As for the validation plugin I think this can not be used.
Validation plugin as I known works on forms. When edit here we do not have a form. But this make me think that there is no problem to include a form element here.

I think that the good way is to do that at server side – i.e. to add content like links, buttons and etc. at server side and attach them a click events
