  gridview, build hyperlinkfield dynamically

  Mar 28, 2019 07:18 AM|metallonorg|LINK

  Dear .net Experts,

  I have build my gridview and it shows fine but now I need a custom link that enables
  the user to view the file. For that I need to build the link dynamically using
  the other gridview column content in the link path.

  datanavigateurlformatstring="http://....com/Members/files/{id}+/+{filename}" />

  How can I do this?

  ..
  <Columns>
  <asp:CommandField ShowDeleteButton="True" DeleteText="Delete this" />
  <asp:BoundField DataField="Filename" HeaderText="File" SortExpression="Filename" />
  <asp:BoundField DataField="Comment" HeaderText="Comment" SortExpression="Comment" />
  
  <asp:hyperlinkfield headertext="View"
  datatextfield="View"
  datanavigateurlformatstring="http://....com/Members/files/{id}+/+filename" />
  
  <asp:BoundField DataField="ID" HeaderText="" SortExpression="ID" InsertVisible="False" Visible="false"
  ReadOnly="True">
  <ItemStyle BackColor="White" Font-Size="Smaller" ForeColor="White" />
  </asp:BoundField>
  </Columns>

  Replace your HyperLinkField by this one

  <asp:HyperLinkField DataNavigateUrlFields="ID, File" DataNavigateUrlFormatString="~/Members/files/{0}/{1}" Text="View" HeaderText="View" />

  Hi metallonorg,

  According to your description and code, I suggest that you could write the string including the format {0}.

  You could refer to: https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.webcontrols.hyperlinkfield.datanavigateurlformatstring?view=netframework-4.7.2

  Note:

  The format string is applied only when the DataNavigateUrlFields property is set.

  The format string can be any literal string and usually includes a placeholder for the field's value.

  ..
  <Columns>
  <asp:CommandField ShowDeleteButton="True" DeleteText="Delete this" />
  <asp:BoundField DataField="Filename" HeaderText="File" SortExpression="Filename" />
  <asp:BoundField DataField="Comment" HeaderText="Comment" SortExpression="Comment" />
  
  <asp:Hyperlinkfield HeaderText="View" 
  DataTextField="View"
  DataNavigateUrlFields="ID,Filename"
  DataNavigateUrlFormatString="http://....com/Members/files/id={0}&filename={1}"/>
  
  <asp:BoundField DataField="ID" HeaderText="" SortExpression="ID" InsertVisible="False" Visible="false"
  ReadOnly="True">
  <ItemStyle BackColor="White" Font-Size="Smaller" ForeColor="White" />
  </asp:BoundField>
  </Columns>

  Best Regards,

  Jenifer
