  Making a hyperlink in GridView

  Nov 23, 2012 02:53 PM|LINK

  Hi All,

  I'm using the <asp:gridview control and I have a boundfield that shows the path to a document. How can I make this a hyperlink so that the document can be opened by the user?

  <asp:BoundField DataField="File" HeaderText="Path" ReadOnly="true" SortExpression="File" />

  thanks

  You can use ItemTemplate to put hyperlink control, and write code behind code to download the file onClick event of this.

  If you want to persist with use of BoundField, you can refer this simple example -

  Mark it as Answer, if you feel so. Thanks

  Hi，

  Try <asp:HyperLink> by setting NavigateUrl and Text properties，please have a look at this：

  [aspx]

  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
                  <Columns>
                      <asp:TemplateField HeaderText="Id">
                          <ItemTemplate>
                              <%#Eval("Id") %>
                          </ItemTemplate>
                      </asp:TemplateField>
                      <asp:TemplateField HeaderText="Link">
                          <ItemTemplate>
                              <asp:HyperLink NavigateUrl='<%#Eval("Name") %>' runat="server" Text='<%#Eval("Id") %>' />
                          </ItemTemplate>
                      </asp:TemplateField>
                  </Columns>
              </asp:GridView>

  [cs] 

  protected void Page_Load(object sender, EventArgs e)
          {
              if(!IsPostBack)
              {
                  GridView1.DataSource = new[] 
                  {
                      new{Id=1,Name="http://www.google.com"},
                      new{Id=2,Name="http://www.baidu.com"}
                  };
                  GridView1.DataBind();
              }
          }

  HI All,

  I have changed my bound field to:

  <asp:TemplateField HeaderText="Path" SortExpression="File">
                                  <ItemTemplate>
                                      <asp:HyperLink NavigateUrl='<%#Eval("File") %>' Text='<%#Eval("File")%>' runat="server" Target="_blank"></asp:HyperLink>
                                  </ItemTemplate>
                              </asp:TemplateField>

  Now my Path appears as a hyperlink, but when I click on the hyperlink nothing happens.

  I have one file that is a full path in the form "C:\temp\MyDoc.doc" clicking the link does nothing.

  Other's are in my temp path and show as "\temp\1234.htm" for example. Here it is trying to go to http://localhost:3209/temp/1234.htm" and I receive resource cannot be found error

  No, you cannot do to write down your absolute path, others who accessing the website cannot access the file through your local file web path.

  Hi again,

  Your "Name" property something like this should contain:

  /Temp/xxxx.htm

  And there should be a folder called "Temp" under the root of your proj, with the specific file there.

  Hi,

  You may  use this approach

  CodeBehind

  protected void Page_Load(object sender, EventArgs e) 
      { 
         
          dynamic dirInfo = new DirectoryInfo(Server.MapPath("~/YourFolder")); 
          if (dirInfo.Exists) 
          { 
              GridView1.DataSource = dirInfo.GetFiles(); 
              GridView1.DataBind();        } 
   
   
      }

  The gridView

  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"> 
      <Columns> 
      <asp:TemplateField Headertext= "List of Files"> 
      <ItemTemplate> 
          <asp:HyperLink ID="HyperLink1" runat="server" Text='<%# Eval("Name") %>'  
          NavigateUrl =  '<%# "~/YourFolder/" + Eval("Name") %>'> 
          </asp:HyperLink> 
      </ItemTemplate> 
      </asp:TemplateField> 
      </Columns> 
   </asp:GridView>
