Can you assign the pagecount property of an asp net gridview

Introduction

ASP.NET is a popular programming used for developing web applications. One that arises when working with ASP.NET is whether it is possible to assign the property of an ASP.NET GridView. In this article, we will explore this question and provide examples to demonstrate how it can be achieved.

Assigning the PageCount Property

The PageCount property of an ASP.NET GridView is read-only, which means it cannot be assigned a value. However, we can indirectly set the PageCount by manipulating the data source or using custom .

Example 1: Manipulating the Data Source

One way to assign the PageCount property is by manipulating the data source of the GridView. Let's consider an example where we have a SqlDataSource control bound to the GridView:





In this example, the GridView is bound to a SqlDataSource control, which retrieves data from a database table “Products”. The number of pages in the GridView will be determined by the number of records in the data source.

Example 2: Using Custom Logic

If you want to assign the PageCount property based on custom logic, you can do so by handling the PageIndexChanging event of the GridView. Let's consider an example where we want to 10 records per page:


protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.PageSize = 10;
    GridView1.DataBind();

    // Calculate the PageCount based on the total number of records and page size
    int totalRecords = GetTotalRecords();
    int pageCount = (int)Math.Ceiling(()totalRecords / GridView1.PageSize);
    GridView1.PageCount = pageCount;
}

In this example, we handle the PageIndexChanging event of the GridView and set the PageIndex and PageSize properties accordingly. We then calculate the PageCount based on the total number of records and the page size. Finally, we assign the calculated PageCount to the GridView.

Conclusion

While the PageCount property of an ASP.NET GridView is read-only, we can assign it indirectly by manipulating the data source or using custom logic. In this article, we explored two examples that demonstrate how to achieve this. By these techniques, you can effectively manage the pagination of your ASP.NET web applications.
