See here the answer.

It do work with loadonce:true, but you should take in the consideration when you should call the $(“#grid”).jqGrid('getGridParam','data'). You can do this after the data

Ohhh, Chico!!!

It seems to me you are master to make simple things complex. Sorry!

The problem is that Tree Grid is implemented to support only remote data: datatype:”json” and treedatatype: “json”. The “local” datatype is not full supported. For example you can't fill the tree grid using datatype:”local”, treedatatype: “local” and data:this.Data. There are a workaround if you use addJSONData, but it is the workaround only and not real the main way implemented by design.

So I recommend you to change your code and use the url parameter of jqGrid. jqGrid will get asynchronous requests to the server and fill the jqGrid contain with the server resonse. In the case you will have no problems and on the node expanding a new request to the server with additionally parameters, which describes the current node, will be send to the server.

If needed you can use functions in the jsonReader.

It's depend on environment which you use. It you has ant tool, then see here. Other way could be to concatinate all jqGrid modules which you need in one file and run any minification tool (see here), for example YUI Compressor. It is important to hold the order of some jqGrid modules. I recommend you to open jquery.jqGrid.min.js and examin the order of modules in the comment at the beginning of jquery.jqGrid.min.js:

Modules: grid.base.js; jquery.fmatter.js; grid.custom.js; grid.common.js; grid.formedit.js; grid.filter.js; grid.inlinedit.js; grid.celledit.js; jqModal.js; jqDnR.js; grid.subgrid.js; grid.grouping.js; grid.treegrid.js; grid.import.js; JsonXml.js; grid.tbltogrid.js; grid.jqueryui.js;

If you are sure that you don't need some from the modules you can reduce the list.

I hope that in the short time will be published jqGrid 4.0.1. If it will be before your development will be finished you will need nothing to do.

Hello Chico,

Sorry, but I don't understand what you do. Which “data array” and how you update? What you do inside of onSelectRow event (onRowSelected event not exist)?

I hate if one explains about the program instead of just posting the code. The code say what you do and the explanation say only what you want to do.

There are many possibility to solve you problem. For example you can use postData parameter to send edditional (also absolutely dynamic) informations to the server of you can change any time the value of url parameter of jqGrid. The event onCellSelect is one more event which can be helpful for you. If all this gives you not what you need you can find “div.treeclick” elements unbind the original onclick event handler and bind you own one (see here).

The main problem is that I don't really understand your problem and so it's difficult for me to recommend you somthing, because some more simple thing probably can solve your problem.

Best regards
Oleg

Hello Chico80,

what you asked is already the default behavior of the Tree Grid. If the user expanding the tree node it will be additional request to the server will be send where three additional parameters will be send: nodeid, parentid and n_level

Inside of onContextMenu event handler you can use
var rowId = $(event.target).closest("tr.jqgrow").attr("id");

to get the rowId. Inside of 'edit', 'add' and other popup menu handler you can use t.id

I find encoding of large texts not the best way. With respect of Encoding.UTF8.GetBytes or Encoding.ASCII.GetBytes you can get byte representation of any string and with respect of MD5CryptoServiceProvider.ComputeHash you can calculate the MD5 from the bytes. Then you can convert the MD5 value to HEX or to Base64. In the database you can save the MD5 directly as binary and in HTML use the values converted to HEX or to Base64. So instead of the usage long (even encoded) texts as id you can use short values.

Regards
Oleg
