Examples¶

With a simple fixed collection specifier¶

{
  "_Type": "Page",
  "_Name": "FilterPage",
  "Controls": [
    {
      "_Type": "Control.Type.FormCellContainer",
      "_Name": "FormCellContainer",
      "Sections": [
        {
          "Controls": [{
            "_Type": "Control.Type.FormCell.MultiSorter",
            "_Name": "OrderBy",
            "AllowEmptySelection": true,
            "Caption": "Sort By",
            "Items": ["OrderId", "BusinessArea", "OrderType"],
            "IsEditable": true,
            "HelperText": "This is helper text",
            "Validation": {
              "Message": "This is validation view message",
              "Visible": true,
              "SeparatorVisible": true,
              "Styles": {
                "Message": "ValidationMessage",
                "ValidationView": "ValidationView"
              }
            },
            "Styles": {
              "Caption": "CaptionStyleClassName",
              "MutiSorter": "BackgroundClassName",
              "Items": {
                "DisplayValue": "DisplayValueStyleClassName",
                "DirectionLabel": "DirectionLabelStyleClassName"
              }
            }
          }]
        }
      ]
    }
  ]
}

Set Style for MultiSorter control¶

Since MultiSorter control has nested control style format, like this:

"Styles": {
  "Caption": "CaptionStyleClassName",
  "MutiSorter": "BackgroundClassName",
  "Items": {
    "DisplayValue": "DisplayValueStyleClassName",
    "DirectionLabel": "DirectionLabelStyleClassName"
  }
}

If we want to set style for DisplayValue or DirectionLabel, we could call setStyle() like this:

multiSorterControl.setStyle("DisplayValueStyleClassName", "Items/DisplayValue");
multiSorterControl.setStyle("DirectionLabelStyleClassName", "Items/DirectionLabel");

With a complex fixed collection specifier with customized ascending and descending labels. If the value is not specified, Ascending and Descending will be the default value.¶

{
  "Controls": [
    {
      "Sections": [
        {
          "Controls": [{
            "_Type": "Control.Type.FormCell.MultiSorter",
            "_Name": "SortFilter",
            "AllowEmptySelection": false,
            "Caption": "Sort By",
            "Items": [{
              "ReturnValue": "OrderId",
              "DisplayValue": "Job ID",
              "AscendingLabel": "Smaller First",
              "DescendingLabel": "Larger First"
            }, {
              "ReturnValue": "OrderDescription",
              "DisplayValue": "Description"
            }, {

              "DisplayValue": "Priority",

              "DescendingLabel": "Lower"
            }],
            "IsEditable":true
          }]
        }
