Hello Andrus,

I verified that in case of the typing

\<a

inside the searching toolbar the jqGrid send

filters={"groupOp":"AND","rules":[{"field":"Est","op":"cn","data":"\\<a"}]}

as the additional parameter to the server. It's absolutely correct. So you have to search for the error in your server code.

You second question about the usage of “formatter”: null seems a pure C# question

After I read the post I verivied in both documantation and the source code, but didn't found the formatter:'password'. So everything is clear. The formatter:'password'

You can just save the JSON data in the file. Depend on the jQuery version and from the settings on your web server it can be important which file extenstion you choose for the file having JSON data. Try to use .json file extension. See the demo which use the JSON file as an example.

Hidding is not the same as removing. If you have for example data like {id:5,total:10,free:20,used:30,percentage:40} you will recive the row in the table like

<tr id="5">

5

10 20 30 40

If you just remove the id column from the colModel you will have

<tr id="5">

10 20 30 40

So the data which will be produced on the page will smaller and you will not have the duplicates of the information. As the rowid will be used the id of the

element and the contain of the hidden id column will never used.

So I recommend you better just remove the id column from the colModel. (See my answer on the same your question on the stackoverflow.com)

It seems for me mostly like the wrong usage of row ids. One uses

data: [


You can use beforeSelectRow event handle to do this. Inside of your handler you can test something and then return false to prevent the row selection.
