How to define number of rows of GridView at runtime in code behind using C#

I need to develop such a program in which the GridView's rows should be decided at run time.

i.e. I have a table in database called dealer capacity.

Dealer_ID       Capacity
D0001                5

Now when the Dealer D00001 is selected from combo box the number of rows in grid view should be 5. I want to use the template field also.

My code for GridView is:

<asp:GridView ID="grdlicence" runat="server" DataKeyNames="Version_id" GridLines="None" BorderStyle="Solid" AutoGenerateColumns="false" AllowSorting="true"     
        CssClass="mGrid table" 
        PagerStyle-CssClass="pgr" 
        AlternatingRowStyle-CssClass="alt" >
             <Columns>
                 <asp:BoundField DataField="Version_name" ItemStyle-CssClass="uppercase" ItemStyle-Width="150px"   HeaderText="Version" HeaderStyle-HorizontalAlign="Left" />

                <asp:BoundField DataField="Version_id" Visible="false" HeaderText="Version" HeaderStyle-HorizontalAlign="Left" />

              <asp:TemplateField HeaderText="Price">
                <ItemTemplate>
                       <center><asp:TextBox ID="txtprice" CssClass="alignments TextStyle" MaxLength="5"  runat="server" ></asp:TextBox></center>
                </ItemTemplate>
              </asp:TemplateField>

              <asp:TemplateField HeaderText="Licence Id">
                <ItemTemplate>
                       <center><asp:TextBox ID="txtlicenceid" CssClass="alignments uppercase"  runat="server" ></asp:TextBox></center>
                </ItemTemplate>
              </asp:TemplateField>


              <asp:TemplateField HeaderText="Purchase Date">
                <ItemTemplate>
                       <center><asp:TextBox ID="txtpurchasedate"  onfocus="showCalendarControl(this);"  CssClass="alignments TextStyle"   runat="server"></asp:TextBox></center>
                </ItemTemplate>
              </asp:TemplateField>


              <asp:TemplateField HeaderText="Expiry Date">
                <ItemTemplate>
                       <center><asp:TextBox ID="txtexpirydate"  onfocus="showCalendarControl(this);"  CssClass="alignments TextStyle"   runat="server"></asp:TextBox></center>
                </ItemTemplate>
              </asp:TemplateField>

                 <asp:TemplateField HeaderText="Upload File">
                <ItemTemplate>
                     <center><asp:FileUpload ID="fileUpload" runat="server"  /></center> 
                </ItemTemplate>
              </asp:TemplateField>


           </Columns>

           </asp:GridView>

You can use the linq Take() and pass the number as parameter.

Updated according to the comment, use following code.

grdlicence.DataSourse= ds.Take(5);
grdlicence.DataBind();

You need to define PageSize for your GridView and remember to set AllowPaging to true for the GridView

GridView.PageSize Property

Gets or sets the number of records to display on a page in a GridView control.

The default is 10.
