Table Grid

The Table Grid control is a type of Display control that obtains data from a Sheet, connector, or other data source and displays it in a table format. The table can be sorted, filtered, paginated, and downloaded, and includes features like row selection and insertion, server-side pagination, and custom columns.

Table Grid

Binding Data Options

Table Grid control accepts array of objects to display data. There are different ways in which you can bind data to the Table Grid control.

Static Data Option

To display static options in the Table Grid control, you can use the Bind Data option.

The Bind Data option must be specified as an array of objects. For example:

  [
  {
    "id": 1,
    "name": "Carlyn Bartle",
    "email": "Carlyn.Bartle@example.com"
  },
  {
    "id": 2,
    "name": "Murry Rowsel",
    "email": "Murry.Rowsel@example.com"
  }
]

Dynamic Data Option

You can dynamically Bind options by fetching data from Data queries, Sheets or Custom functions by binding the response to the Data Bind option. For example:

Let's fetch data from a configured SQL connector."We have a predefined query, getDetails, that fetches data from the SQL database using the connector." The SQL syntax for this query:

  SELECT * FROM orderdetails

In the Table Grid control, Bind Data Options, select the Quick Select -> Connector Library -> SQL_Connector -> getDetails

Binding Dynamic data from connector to Table Grid control.

Real-time visualization of table grid control changes in the builder view, with updated data fetched from an SQL database.

Server-Side Pagination

Server-side pagination is a technique for displaying large data sets in a web application by dividing the data into pages and only sending the current page to the browser. This can improve performance and make the data easier to manage.

Key Benefits

• By only fetching the required data for the current page, server-side pagination reduces the load on both the client and server, leading to faster response times.
• This method handles large data sets efficiently, as it doesn't require loading all data at once.
• Improves the user experience by ensuring quick data retrieval and display, even with extensive data sets.

Client-Side Pagination

Client-side pagination is another method used to manage large data sets in web applications. Unlike server-side pagination, where only the necessary data for the current page is fetched from the server, client-side pagination involves fetching the entire data set upfront and then dividing it into pages locally in the DronaHQ.

Key Benefits

• Since all data is loaded at once, client-side pagination is best suited for smaller data sets. For very large data sets, this can lead to performance issues such as slow loading times and high memory usage.
• Implementation is simpler as it doesn't require server-side changes or multiple requests to fetch data.
• Once the data is loaded, navigation between pages is instant, providing a smooth user experience without additional server requests.

info

To know about implementing pagination in Tablegrid control within DronaHQ, understand the types and configurations necessary for efficient data management. Pagination types include server-side, client-side, and cursor-based, each with unique benefits. Configure properties like pagination bar location and default cursor values to enhance functionality. Additionally, explore how to implement pagination for MySQL, GraphQL, and REST API data sources. For a comprehensive guide, you can read the Pagination in Tablegrid Control article.
