    In This Topic

    Sorting is another way to organize data in ascending or descending order. In FlexReport, sorting is achieved by using DataSource.SortDefinitions.

    Lets say you want to view the list of employees with their names in ascending order. In this case the list should be sorted by First Name. The following steps illustrate how to Sort the names of the list of employees in alphabetical order. This example uses sample created in FlexReport Quick Start.

    1. Add a C1Button to the form in the FlexReport Quick Start project.
    2. Set the C1Button Name to 'sortC1Button' and Text to 'Sort Report by Employee First Name'.
    3. Create Click event as sortC1Button_Click.
    4. Add the following code.
      Private asc As Boolean = True
          Private Sub sortC1Button_Click(sender As Object, e As EventArgs) Handles Button2.Click
              If asc Then
                  Dim sd As New SortDefinition("[FirstName]", SortDirection.Ascending)
                  asc = False
                  asc = True
              End If
          End Sub
       bool asc = true;
              private void sortC1Button_Click(object sender, EventArgs e)
                  if (asc)
                      SortDefinition sd = new SortDefinition("[FirstName]", SortDirection.Ascending);
                      asc = false;
                      asc = true;
    5. Preview the report. Click Employees button to render the report.
