RussianQuestion
I've been trying to get this to work for days upon days and it seems like one thing after another. Initially, I finally tracked it down to trouble passing ASP.NET dates in the JSON string back to the grid. I am now using JSON.NET and the dates are coming back the way they should be I'm stuck right back where I alwasy seem to be. Here is my code, returned json string, and jqGrid code also: (I'm sorry it's so long, but I just didn't want to leave anything out in case that was the part that was screwing me up)! Basically, I am continually stuck in the success method of the ajax call where I try to addJSONData.... as of right now I am getting an error from Firebug that says: invalid property id ({total:1,page:1,records:5,[{"ROWID":1,"...rName":"BCC","SubmitterID":"BCC4010","Su
ANY HELP WOULD BE SO GREATLY APPRECIATED! I Want to use this plug in so much, but I am going absolutely nuts trying to make it work!
Thanks in Advance, Briana :-)

Solution
Actually, tvanfosson makes an excellent point with the requirement of the 'rows' identifier. I'm unfamiliar with jMSAjax so my comments may be null and void. I'm glad to be aware of it.
Could it be something as simple as the return type being string? That is, when the response is evaluated, you end up with the encapsulated string not the json object.
I've been in a similar place myself. I found the options to be either, create a business object that represents the expected jqGrid response and return the object not a string (ASP.NET will serialize it as JSON for you!) or modify the jqGrid to eval the response twice (messy).
OTHER TIPS
missing an identifier for that list:
return_value = {
total:1,
page:1,
records:5,
[{ .. some X12 messages ..}]
}
I have spent a lot of time trying to get jqGrid to work with ASP.NET using JSON. Now that I have it working, I would like to share it with you. Hoping to save time for other people.
I found the answer here. This is not to say there are no other ways to make this work (I'm sure there are). But this one definitely works.
To summarize the things that made a difference for me:
- Using "datatype: function() {" on the settings of the jqGrid, and NOT using "datatype: json". The function uses "$.ajax(" to call the service. Looking in Fiddler, this changed the data coming back to the browser, to be pure JSON (instead of JSON wrapped in XML).
- Using a web service that returns a data class (in the schema jqGrid expects). I first tried using JSON.NET but for some reason the message showed (in Fiddler again) to be escaped with \ for every quote in the string. I'm pretty sure you can get JSON.NET to work. But it works just as well without it.
It doesn't look like you are adding the rows property identifier. Try changing:
json.Append(JsonConvert.SerializeObject(objPageCollection))
to
json.Append("rows: " + JsonConvert.SerializeObject(objPageCollection))
If this doesn't work, I suggest that you simplify the problem -- reduce the data to one row, for example -- and see if you can get it working with simpler data, then gradually add more stuff back into it.
