FormView.PageCount Property

Gets the total number of pages required to display every record in the data source.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public virtual int PageCount { get; }
/** @property */
public int get_PageCount ()

public function get PageCount () : int

Not applicable.

Property Value

The number of items in the underlying data source.

When the paging feature is enabled (when the AllowPaging property is set to true), use the PageCount property to determine the total number of records in the underlying data source.

NoteNote:

Because the FormView control displays only one record at a time, this value corresponds to the total number of pages required to display every record in the data source. This value is not accurate until after data-binding occurs.

To determine the index of the current record from the underlying data source, use the PageIndex property.

The following example demonstrates how to use the PageCount property to determine the total number of records displayed in the control.

    FormViewRow pagerRow = EmployeeFormView.BottomPagerRow;

    // Get the Label controls that display the current page information 
    // from the pager row.
    Label pageNum = (Label)pagerRow.Cells[0].FindControl("PageNumberLabel");
    Label totalNum = (Label)pagerRow.Cells[0].FindControl("TotalPagesLabel");

    if ((pageNum != null) && (totalNum != null))
    {
      // Update the Label controls with the current page values.
      int page = EmployeeFormView.PageIndex + 1;
      int count = EmployeeFormView.PageCount;

      pageNum.Text = page.ToString();
      totalNum.Text = count.ToString();
    }
