You can simple (as described in grid options) whitout using any event

jQuery("#mygrid").jqGrid({

...

postData: { un: “x”, ci: “y”, pll: “z” },

...

});

This will apend the items to postdata array

there is an event that runs before the first request. It is named appropriately enough, beforeRequest:

I called appendPostData in that event process to add the required variables. 

$(”#gridName”).appendPostData({ un: “x”, ci: “y”, pll: “z” });

This is a much more efficient way of controlling the dataset on first load. 

I found its definition in the jqGrid Wiki event section. The wiki is not complete yet but seems to include newly added functionality. 

Thank you Tony for adding this event.

The grid is loaded via json fed from a url. The server gets the initial request on load but never gets the second reload fired on loadComplete. 

    $("#gridName").jqGrid({

        url: 'WSGridGetJson.aspx',

        datatype: "json", 

        mtype: 'POST', ..........

I've traced the process to grid.base.js line 588

populate = function () {

     if(!ts.grid.hDiv.loading) { ...

It appears that populate will only happen if the grid is not loading and I assume that loadComplete is part of the loading process. This must have been different in version 3.4.2. 

Can I clear the loading flag from on loadComplete process. If so, how and what might be the reprecussions of such a change is standard process? Can PostData be set before the grid is created in verison 3.5.3. ( I believe this method of shaping grid data was devised back in version 3.1, perhaps the process has changed since then)

The grid is reloaded on loadComplete to set PostData to variables acquired after the page containing the grid is created to control the loaded data set. 

Called from on loadComplete function.

        $("#gridName").setPostData({ un: "x", ci: "y", pll: "z" });

        $("#gridName").trigger("reloadGrid");
