Properties and Methods

See the complete documentation at jqWidget's site: http://www.jqwidgets.com/jquery-widgets-documentation/documentation/jqxgrid/jquery-grid-getting-started.htm

Example

Dim data, source, dataAdapter
data = generatedata(50)     'generatedata is a function which returns grid data
source = {localdata: data, datatype: "array"}
dataAdapter = new $.jqx.dataAdapter(source)
              
Grid1_settings.source = dataAdapter
Grid1_settings.columns = [ _
    { text: "First Name", dataField: "firstname", width: 100 }, _
    { text: "Last Name", dataField: "lastname", width: 100 }, _
    { text: "Product", dataField: "productname", width: 180 }, _
    { text: "Quantity", dataField: "quantity", width: 80, cellsalign: "right" }, _
    { text: "Unit Price", dataField: "price", width: 90, cellsalign: "right", cellsformat: "c2" }, _
    { text: "Total", dataField: "total", cellsalign: "right", minwidth: 100, cellsformat: "c2" } _
  ]

Change the font size of a grid:

$("#Grid1 .jqx-widget-content").css("font-size","30px");

Delete SelectedRow: requirement: Grid1 must have selectionmode=singlerow set.

Function Button1_onclick()
  Dim SelectedRowIndex
  SelectedRowIndex = $("#Grid1").jqxGrid("getselectedrowindex")
  Dim RowsCount 
  RowsCount = $("#Grid1").jqxGrid("getdatainformation").rowscount
              
  If (SelectedRowIndex >= 0 && SelectedRowIndex < RowsCount) Then
      Dim Id, Commit
      Id = $("#Grid1").jqxGrid("getrowid", SelectedRowIndex)
      Commit = $("#Grid1").jqxGrid("deleterow", Id)
    End If
    
End Function

Respond to a cell getting selected:

Function Grid1_oncellselect(event)
   Dim Headername, HeaderIndex
   Headername = $("#Grid1").jqxGrid("getcolumn", event.args.datafield).text
   Label1.textContent = "Row: " & event.args.rowindex &", Column: " & Headername
   HeaderIndex = $("#Grid1").jqxGrid("getcolumnindex", Headername )   
   'Result -> Index from Headername
   Label2.textContent = "Header Index: " + HeaderIndex
End Function

Value from Selected Row and Result in JSON Format

Function Grid1_oncellselect(event)
 Dim SelectedRow, dataFromSelectedRow
 SelectedRow =  event.args.rowindex

 // Result in JSON-Format   
 dataFromSelectedRow =  $("#Grid1").jqxGrid("getrowdata", SelectedRow);
 
 MsgBox dataFromSelectedRow["firstname"]
 MsgBox dataFromSelectedRow["lastname"]
 MsgBox dataFromSelectedRow["productname"]
 MsgBox dataFromSelectedRow["quantity"]
 MsgBox dataFromSelectedRow["price"]
 MsgBox dataFromSelectedRow["total"]

End Function

Sample Code (Read from XML to JqxGrid)

Dim gedata, source, dataAdapter, row, req, err, data

  If req.readyState<>4 Then Exit Function 'ignore progress reports
  If req.status<>200 Then 'failure
    Exit Function
  End If
  If Left(req.responseText,5)<>"<?xml" Then
    console.log("XML not received" & req.responseText)
    Exit Function
  End If
  
  data = $.xml2json(req.responseText)

Export JqxGrid

You can export a JqxGrid as Excel, XML, CSV, TSV, HTML, PDF or JSON

$("#jqxgrid").jqxGrid('exportdata', 'json');

or

you can export the data to a local variable.

Dim ExportedDatas
Function Button5_ontouchstart()
  Rem Datas in Variable as JSON-Format
  ExportedDatas = $("#Grid1").jqxGrid("exportdata", "json");

Rem  ExportedDatas = $("#Grid1").jqxGrid("exportdata", "json", "Filename.json");

End Function

• exportdata : Modulname
• json: Export methods ( 'xls', 'xml', 'html', 'json', 'tsv' or 'csv')
• Filename.json : Filename for exportet datas
