Serenity.is how to disable rows in a grid - TypeScript

Serenity.is is a great framework for developing web applications. One of the features that it offers is the ability to create grids. However, sometimes you may want to disable some rows in the grid. In this article, we will see how we can disable rows in a grid using TypeScript.

Prerequisites

Before we proceed, you must have the following:

• Basic knowledge of TypeScript
• A working installation of Serenity.is

Disabling Rows in a Grid

To disable rows in a grid, we need to modify the getRowClass property of the Slick.Grid object. Here is an example:

gridOptions: Slick.GridOptions = {
  // other options...
  getRowClass: (item: any) => {
    if (item.IsDisabled === true) {
      return "disabled";
    } else {
      return "";
    }
  },
};

In the above code, we are checking if the IsDisabled property of the item is set to true. If it is, we set the CSS class of the row to disabled. Otherwise, we leave it empty.

Adding the CSS Class

After we have set the CSS class of the row, we need to add the corresponding styles to our CSS file. Here is an example:

.disabled {
  color: #888;
  pointer-events: none;
}

In the above code, we are setting the color of the disabled rows to a light grey and disabling pointer events. This will prevent users from being able to click on the disabled rows.

Conclusion

In this article, we have seen how we can disable rows in a grid in Serenity.is using TypeScript. By using the getRowClass property and adding the appropriate CSS styles, we can easily disable rows in our grids.
