I'm looking for a way to control what is displayed when an exception is thrown during postback (when pressing submit).

I couldn't figure it out so I suggest the following changes in grid.formedit.js. I added a function pointer parameter (in both editGridRow and delGridRow):
errorTextFormat

And in the complete callback to the ajax call, in the no success branch, I changed the code to:

if (Status != "success") {
    ret[0] = false;
    if ($.isFunction(rp_ge.errorTextFormat)) {
        ret[1] = rp_ge.errorTextFormat(data);
    } else {
        ret[1] = Status + " Status: " + data.statusText + " Error code: " + data.status;
    }
} else {

As you can see, this gives the caller a chance to analyze data and return a message of his or her choice.

If there's already a way to achieve this, please correct me.

Kind regards, Ingo

Hello Ingo!

You suggestion has till now no respond, so I’ll write my opinion about it.

I find you suggestion very useful. I had very close suggestion by the way, but not yet wrote it Smile . So I’ll write some arguments which describe why your suggestion is gut.

First of all, the standard error message:

ret[1] = Status+" Status: "+data.statusText +" Error code: "+data.status;

should has block quotes:

ret[1] = Status+" Status: '"+data.statusText+
" '. Error code: "+data.status;

(compare text "error Status: Internal Server Error Error code: 500" with the text "error Status: 'Internal Server Error'. Error code: 500")

and be localizable with additional properties in grid.locale-XX.js.

Next, respond from the server in the case of errors can contains detailed error description in the data.responseText. For example, in my environment server response has always JSON format and every exception throws from the server follows failed respond with the text of exception message in data.responseText as Detail property. For example,

throw new NotImplementedException ();

on the server follows to respond with code 500 and responseText

{"Detail":"The method or operation is not implemented."}

Other exceptions like a typical DBConcurrencyException () exception have responds in the same format, but another content of responseText of cause. The standard error message displayed by editGridRow and delGridRow functions for all exceptions will be "error Status: Internal Server Error Error code: 500" every time.

A custom error format function like errorTextFormat introduced by you can makes error messages more understandable.

Best regards

Oleg

Hello,

Since jqGrid is user oriented and mostley developed to make the developer life easy, so I added this request.
