Advanced Column Style

style property can be used by the advanced ways below.

• change style by each record

This can be done by functions below.

• use the function
• use the instance of Style class

<div class="sample3 demo-grid small"></div>
<label>change background color of text</label>
<select class="sample3theme">
  <option value="" selected="true">default</option>
  <option value="red">red</option>
  <option value="#DFF">#DFF</option>
</select>

const textFieldStyle = new cheetahGrid.columns.style.Style();
const grid = new cheetahGrid.ListGrid({
  parentElement: document.querySelector(".sample3"),
  header: [
    { field: "no", caption: "no", width: 50 },

    {
      field: "value",
      caption: "value",
      width: 150,
      columnType: "number",
      //function
      style(rec) {
        return {
          color: rec.value <= 0 ? "red" : undefined,
        };
      },
    },

    {
      field: "text",
      caption: "text",
      width: 150,
      //Style instance
      style: textFieldStyle,
    },
  ],
});
grid.records = [
  { no: 1, text: "sample text", value: 100 },
  { no: 2, text: "sample text", value: 50 },
  { no: 3, text: "sample text", value: 0 },
  { no: 4, text: "sample text", value: -50 },
];

const themeSelect = document.querySelector(".sample3theme");
themeSelect.onchange = function () {
  //change bg color
  if (themeSelect.value === "default") {
    textFieldStyle.bgColor = null;
  } else {
    textFieldStyle.bgColor = themeSelect.value;
  }
};

Header Style

Define column header style by using headerStyle property.

<div class="sample4 demo-grid small"></div>

const grid = new cheetahGrid.ListGrid({
  parentElement: document.querySelector(".sample4"),
  header: [
    { field: "no", caption: "no", width: 50 },

    // default
    { field: "text", caption: "default", width: 150 },

    // color
    {
      field: "text",
      caption: "color",
      width: 150,
      headerStyle: { color: "red" },
    },
    // textAlign
    {
      field: "text",
      caption: "center",
      width: 150,
      headerStyle: { textAlign: "center" },
    },
    // textBaseline
    {
      field: "text",
      caption: "bottom",
      width: 150,
      headerStyle: { textBaseline: "bottom" },
    },
    // bgColor
    {
      field: "text",
      caption: "bgColor",
      width: 150,
      headerStyle: { bgColor: "#5f5" },
    },
    // font
    {
      field: "text",
      caption: "font",
      width: 150,
      headerStyle: { font: "9px sans-serif" },
    },
    // textOverflow
    {
      field: "text",
      caption: "textOverflow clip",
      width: 150,
      headerStyle: { textOverflow: "clip" },
    },
    {
      field: "text",
      caption: "textOverflow ellipsis",
      width: 150,
      headerStyle: {
        textOverflow: "ellipsis" /*In the header this is the default*/,
      },
    },
  ],
});
grid.records = [
  { no: 1, text: "data" },
  { no: 2, text: "data" },
  { no: 3, text: "data" },
];
