I didn't find in the forum and in the demo one full example how to use the updateGridRows method (thank you, I already read the doc).

I would like to evict the flickering on reload.

I suppose, for each row of the grid, I must extract the id and compare the same row in the received postdata.

If the ids are equal then I must update the row of the grid with updategridrows.

In order to do all these things I must declare one function as datatype.

Is it the good method ?

Hello,

IMHO not a desired solution

The purpose of updateGridRows is to update data with equal id's and to to add new one.

Some possible solution

$(“#grid”).jqGrid({

…

loadonce:true,

…

});

then for your solution

setInterval( function(){

$.ajax({

….

complete: function(response, status) {

// get your data here and pass it to the grid

$(“#grid”).updateGridRows(…);

}

});

},2000);

Regards

Tony

Hello,

Which other people do not understand this?

The method is standart jqGrid method and there is nothing something special.

The method is applied to specified grid with parameter array and the name of the id row.

Is something that you do not understand?

The passed array replaces the data in the grid if it find the id.

Hi,

tony, you say “The purpose of updateGridRows is to update data with equal id's and to to add new one.”

Do you mean that if it finds the row it updates it and if it does not it adds it to the grid? Because I tried using it and it does update correctly, buit it does not add new row if id is not found. Is there any functionality fo this ( update or add if not found at the same time)?

Thank you in advance.
