2)单击此处按钮

对于单击此处的每个按钮"，必需的事件代码(如

I have One Grid View with Access 2003 Database.

I have Two Columns in Grid View with Databound.

For Every Button of Click Here required Event Code like

Note : Each Button has Diffrent Redirect Code Saved in Database. e.g. ~/pdf/Daasi.pdf

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            DataSourceID="AccessDataSource1" Width="236px" Font-Names="Calibri">
            <columns>

                    SortExpression="Id" />
                <asp:ImageField DataImageUrlField="ImageUrl" HeaderText="Image Url">

推荐答案

如果您的按钮asp.net按钮将此属性添加到您的按钮中

if your buttons asp.net buttons add this attribute to your button

PostBackUrl='<%# "~/" + Eval("saved_postback_url")%>'

嗨 将您的gridview html替换为以下内容.我添加了一个模板字段

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

<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>

重要的是您存储的链接应该是相对链接，否则它将断开.

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