updateFromXML is a great function and works amazingly well.
I populate grids mostly using JSON and need updateFormJson(). Is there such a function?

Please, try to use:
mygrid._refresh_mode=[url, insert_new, del_missed, afterCall]; // parameters the same as in the updateFromXML() method
mygrid.load(url,"json")
Suppose I have the data already, is there a way to update only the changed cells / rows?
Is there a function in which I can pass the data similar to grid.parse() and it would update the grid?
Or do I need to grid.clearAll() and gird.parse() with each change?
Please, try to use:
mygrid._refresh_mode=[url, insert_new, del_missed, afterCall]; // parameters the same as in the updateFromXML() method
mygrid.parse(data,"json")
In: mygrid._refresh_mode=[url, insert_new, del_missed, afterCall]
would the url be ‘’ or undefined or null?
Shame! I apologize for my inattention!
It’s my mistake.
_refresh_mode function does not require the “url” attribute.
mygrid._refresh_mode=[insert_new, del_missed, afterCall]; // the parameters are the same as in the updateFromXML() method
mygrid.parse(data,"json")
I can’t get this work:
ppNew.grid._refresh_mode=[true, true, function(){}];
ppNew.grid.parse(r.data, "json");
whereas, a standard parse does work, so I do not think it is a problem with the data:
ppNew.grid.parseJs(r.data, "json");
I am attaching a screenshot of the error and the data:
Please, refer to the supported “json” format of data:
docs.dhtmlx.com/grid__data_forma … jsonformat
May be, you may try to use the “js” type.
I tried “js” type and that fails too:
ppSearch.grid._refresh_mode=[true, true, function(){}];
ppSearch.grid.parse(r.data, "js");
If the problem still occurs for you please, provide with the sample of your code with the init of your grid and the generated json string.
I got busy and was unable to put together a demo so I wound up using parse().
Today I needed to merge rows into a grid so I wrote a prototype:
dhtmlXGridObject.prototype.mergeJs = function(js, updateCells){
var r, c, a;
for (r=0; r < js.total_count; r++){
if (this.getRowIndex(js.data[r].id) == -1) {
a = [];
for (c=0; c<this.getColumnsNum(); c++){
a.push( js.data[r][this.getColumnId(c)])
}
this.addRow(js.data[r].id, a)
}
}
}
As time permits and when I actually need it, I’ll turn this into a method which will intelligently update the existing columns and delete rows when specified.
