Get Data twice

[simcon94Participant]

Hi,
i have a Grid. The Data for the Grid i get it from the dataAdpater.
This dataAdapter i’d like to give to a PopUp.
Thats not the Problem.
The Problem is, that the PopUp has a jqxDropDownList. In these DropDownList i will give the dataAdapter as source.
In this casse, the DropDownList will call a function in my Controller, even though I already have the data…..
Any Idea?

Thats the Code:

var source =
{
datatype: “json”,
datafields: [
{ name: ‘Id’, type: ‘string’ }
, { name: ‘Name’, type: ‘string’ }
],

addrow: function (rowid, rowdata, position, commit) {
commit(true);
},
updaterow: function (rowid, rowdata, commit) {
commit(true);
},
deleterow: function (rowid, commit) {
commit(true);
$(‘#grid’).jqxGrid(‘refresh’);
},
// get Model Data
url: sk.appHelper.getAppDomainAppVirtualPath() + “/Test/GetDatas”
,async: false
};
var dataAdapter = new $.jqx.dataAdapter(source);

//call Function
preparePopUp(dataRecord.Id, dataAdapter);

function preparePopUp(id, dataAdapterGrid) {
$(“#gridParentMeters”).jqxGrid(
{
width: popUpWidth – 10
, autoheight: true
, source: dataAdapter

, selectionmode: ‘singlecell’
, editable: true
, columnsresize: true
, showtoolbar: true
, showaggregates: true
, showstatusbar: true
, altrows: true
, statusbarheight: 25
, rendertoolbar: function (toolbar) {
var container = $(“

“);
var addButton = $(“

“);
container.append(addButton);
toolbar.append(container);
addButton.jqxButton({ width: 60, height: 20 });
// add new row.
addButton.click(function () {
$(“#gridParentMeters”).jqxGrid(‘addrow’, ‘MeterId’, {}, ‘top’);

});
}
, columns: [
{
text: “Id “, datafield: “Id”, width: 1, hidden: true
, aggregatesrenderer: function (aggregates, column, element) {
var renderstring = “

“;
return renderstring;
}
}
, {
text: ‘@Resources.Name’, columntype: ‘dropdownlist’, displayfield: “Name”, datafield: “Id”, width: ‘80%’,
createeditor: function (row, cellvalue, editor) {
editor.jqxDropDownList({ source: dataAdapterGrid, displayMember: ‘Name’, valueMember: ‘Id’, height: ’25’ });
}

}

]
});
}

Hi simcon94,

It is not necessary to make another server call if you already have the data. You just have to construct a new jqxDataAdapter instance to bind a widget and the data could be local for it, if the data is already downloaded.
