Gridview C#

Introduction:

GridView stands out as a robust and flexible tool for presenting data in C#. It empowers developers to exhibit information in a structured layout, complete with sorting, pagination, and editing functionalities. This component is commonly employed to showcase data sourced from databases or various other repositories, a prevalent practice in web-based applications. Our comprehensive guide delves into GridView in C#, shedding light on its attributes, characteristics, and the process of leveraging it for data visualization.

What is GridView in C#?

Data can be showcased in a structured table format with functionalities such as sorting, paging, and editing by utilizing the C# data presentation control GridView. The Web.UI.WebControls namespace is commonly employed in web-based applications. GridView has the capability to be linked to different data origins including databases, XML files, and other sources of data.

Features of GridView in C#:

Sorting functionality is one of the prominent features of GridView in C#, making it a favored option for presenting data in web applications.

Data in a GridView can be sorted in either ascending or descending order. To sort across multiple columns, hold down the shift key while clicking on the column headers.

• ✅ Pagination:

GridView provides the functionality to paginate data, enabling the presentation of a portion of the data at any given moment. This feature significantly enhances the efficiency of the application, particularly when handling extensive datasets.

• ✅ Modifying:

GridView offers editing functionality, enabling users to modify data within the control itself. This functionality proves beneficial when users require the ability to make alterations to the data being shown in the control.

• ✅ Selection:

GridView enables users to choose data rows, providing the functionality to execute tasks such as deletion, updating, or exporting on the selected rows.

• ✅ Styling:

GridView offers various formatting choices for the data presented within the control. Users have the ability to customize the font, size, color, and additional formatting preferences for the displayed information.

Properties of GridView in C#:

• ✅ AutoGenerateColumns: This attribute in GridView allows automatic generation of columns based on the data source provided, simplifying the process of defining columns manually.

This feature enables the automatic creation of columns depending on the data origin.

• ✅ AllowSorting:

This feature enables you to activate or deactivate data sorting functionality within the GridView.

• ✅ AllowPaging:

This feature permits you to activate or deactivate the pagination of information in the GridView.

• ✅ :

This attribute enables you to display or conceal the header section of the GridView.

• ✅ ShowFooter:

This attribute enables toggling the visibility of the footer section in the GridView.

• ✅ EditIndex:

This attribute enables you to define the position of the row currently being modified within the GridView.

Using GridView in C#:

Implementing a GridView in C# is a simple and uncomplicated process. To begin, you need to add a GridView control to your web form. This can be achieved by conveniently dragging and dropping the control from the toolbox onto your form.

Next, you must connect the GridView control to your data origin. This can be accomplished by assigning the GridView control's DataSource attribute to the data source. In case you want columns to be automatically generated based on the data source, you can enable the AutoGenerateColumns attribute to true.

After connecting the GridView control to your data source, you have the flexibility to personalize its look and functionality by adjusting properties such as AllowSorting, AllowPaging, and EditIndex.

Moreover, GridView offers various events that can be used to customize its functionality. Some essential events of GridView include:

• ✅ RowDataBound:

This function is triggered when a row gets associated with the GridView. It provides the opportunity to customize the appearance of the row.

• ✅ RowEditing:

This event is activated whenever a row in the GridView undergoes editing. It offers the opportunity to validate data or perform additional actions on the row.

• ✅ RowDeleting:

This event is activated each time a row is removed from the GridView. You have the opportunity to validate the deletion or execute any additional tasks prior to removing the row.

• ✅ Sorting:

This event is triggered when the user navigates to a different page within the GridView. It can be utilized to refresh the GridView by binding it with updated data.

Begin by incorporating a GridView control into your web form.

Afterward, generate a dataset and populate it with some information.

C# Code:

Connect the GridView control to the dataset.

C# Code:

GridView1.DataSource = ds.Tables[0];
GridView1.DataBind();

1. Implement sorting and pagination functionality within the GridView component.

C# Code:

GridView1.AllowSorting = true;
GridView1.AllowPaging = true;
GridView1.PageSize = 5;

1. Execute the program and observe the information presented in the GridView component.

Conclusion:

The GridView interface for data presentation in C# is robust and versatile, enabling the presentation of data in a structured format with capabilities like sorting, pagination, and editing. It is commonly employed in web applications to exhibit data sourced from databases or other data repositories. This guide delved deeply into the intricacies of using GridView in C#, covering its functionalities, attributes, and the process of showcasing data using it. Furthermore, we illustrated a demonstration of employing GridView in C# to exhibit data retrieved from a dataset. Given its extensive array of functionalities and attributes, GridView in C# emerges as a commendable option for data display in web applications.
