.NET2.0

I have One Grid View with Access 2003 Database.

I have Two Columns in Grid View with Databound.

1) Id / Name
2) Click Here Button

For Every Button of Click Here required Event Code like

Response.Redirect("~/pdf/daasi.pdf")

or

~/pdf/daasi.pdf

saved in Database.
Now I want to Run Saved Response.Redirect Code when user click on button of gridview.
Note : Each Button has Diffrent Redirect Code Saved in Database. e.g. ~/pdf/Daasi.pdf

VB

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            DataSourceID="AccessDataSource1" Width="236px" Font-Names="Calibri">
            <columns>
                <asp:BoundField DataField="Id" HeaderText="Id" 
                    SortExpression="Id" />
                <asp:ImageField DataImageUrlField="ImageUrl" HeaderText="Image Url">
                
                <asp:BoundField DataField="NameofBook" HeaderText="Name of Book" 
                    SortExpression="NameofBook" />
                <asp:ButtonField ButtonType="Button" DataTextField="ViewLink" 
                    DataTextFormatString="Read Now" SortExpression="ViewLink" Text="Button1" />
                <asp:ButtonField ButtonType="Button" DataTextField="DownloadLink" 
                    DataTextFormatString="Download" SortExpression="DownloadLink" Text="Button2" />
            </columns>
            <emptydatatemplate>
                ImageUrl
            </emptydatatemplate>

hi replace your gridview html with the following. I have added a template field

ASP.NET

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="AccessDataSource1"
      Width="236px" Font-Names="Calibri">
      <Columns>
          <asp:BoundField DataField="Id" HeaderText="Id" SortExpression="Id" />
          <asp:ImageField DataImageUrlField="ImageUrl" HeaderText="Image Url">
          </asp:ImageField>
          <asp:BoundField DataField="NameofBook" HeaderText="Name of Book" SortExpression="NameofBook" />
          <asp:TemplateField HeaderText="View Link">
              <ItemTemplate>
                  <asp:LinkButton ID="lnkViewLink" runat="server" PostBackUrl='<%#  Eval("ViewUrl")%>' Text="View Link"></asp:LinkButton>
              </ItemTemplate>
          </asp:TemplateField>
          <asp:ButtonField ButtonType="Button" DataTextField="DownloadLink" DataTextFormatString="Download"
              SortExpression="DownloadLink" Text="Button2" />
      </Columns>
      <EmptyDataTemplate>
          ImageUrl
      </EmptyDataTemplate>
  </asp:GridView>

important thing is that your stored link should be a relative link otherwise it will break.
