I have created two aspx pages where first page contains a dropDownList control :

XML

<asp:DropDownList ID="ddlGroupBy" runat="server" >
                <asp:ListItem Selected="True" Value="Department" Text="Department Wise" />
                <asp:ListItem Value="Grade" Text="Grade Wise" />
                <asp:ListItem Value="Team" Text="Team Wise" />
                <asp:ListItem Value="Category" Text="Category Wise" />
                <asp:ListItem Value="Location" Text="Location Wise" />
            </asp:DropDownList>

And a button control which redirect me to second page wehen I click it.
Second page has CrystalReportViewerControl which displays .rpt files records.
I have also taken a CrystalReport.rpt file and designed it. In this file Recoeds will be grouped by default “Department Wise”. But I don’t know how to change the Group Name Fields (which is ‘Department’ by default) if user change the dropDownControl’s items appropriately.

You can use Formula Field to change GroupName based on DropDown selection .

Thank You

You Can follow this steps :
1.Save selected value of dropdown in variable 
2.Assgin to Querystring in  Response.Redirect
3.Retrive from Query string in second Page 
4.Assign retrived value to formula field  
5.Finally In Crystal Report ,  Check in If Else and assign value to group name accordingly

Here I have taken One DropDown and Button , on button click , seconf Page will get called.

To Save selected value in variable in first page :

VB

Dim strGroupType As String
strGroupType = ddlInput.SelectedItem.Text.ToString()
Response.Redirect("secondPage.aspx?GroupName=" + strGroupType)

In Second Page , To retrive value from QueryString

VB

Dim strGroupName = Request.QueryString("GroupName")

To Set in Fornula Field

VB

Dim strFormulas(1) As String '
strFormulas(0) = strGroupName.ToString()
rptViewer.SetFormaulas = strFormulas

Finally In Crystal Report :

VB

If {(strGroupName)= "IT"} Then
        grpName := "IT"
           ElseIf {(strGroupName)= "Purchase"} Then
        grpName := "Purchase"
       Else
        grpName := "Department"  'This is default
