I'm looking for a method to reload the grid data (from server) without clearing any set search-filters!

The documentation of the refresh-button in the navigator controls says:

“Enables or disables the refresh button in the pager. When the button is clicked a trigger(“reloadGrid”) is executed and the search parameters are cleared“

Is there any attribute I can define when calling the reloadGrid-method to preserve the search parameters?

Or is there any other method which I can use?

Kind regards,

Klaus.

Hello,

This is partial true. Actually we do not clear the search parameters, but turn the search flag to false. This mean that the search parameters are in the postData object and you can use them.

Here is a trick – you can use the afterRefresh event to turn on the search to true.

…jqGrid('navGrid',{

afterRefresh : function() {

(“#mygrid”).jqGrid('setGridParam',{search:true});

},

…}…);

Regards

Hello Tony!

I've tried your hint, but that doesn't solve my problem.

The search-parameters seem to be cleared on clicking the refresh button.

1) select a filter and click find …
POST http://localhost/htmlclient/server/webserver.dll

Hello,

Uppss, sory for this. Right now I look into the code and we call resetFilters which clear the serch's. Should be added soon.

Sorry again.

Also one possible solution is to add a custom Button and then you can control evrething.

Best Regards

Thank's for the quick answer.

Is there another method or trigger-function I can call to only reload the grid without invoking any cleanup-tasks?

(why I need this? … I would like to trigger an automatic reload of the table data periodically)

Kind regards,

Klaus.

Hello,

As we say in the docs – trigger(“reloadGrid) – reloads the grid with the current parameters just asking again for data with the last settings in postData.

Best Regards
