aspx thread: Hyperlink Columns

Message #1 by "Hugh McLaughlin" <hugh@k...> on Sat, 1 Dec 2001 12:52:52

Hello Everyone and thanks for your help in advance.  I am using a datagrid 

to display a list of books with the database fields ISBN, Title, and 

PublicationDate.  I am trying to format the Title with a hyperlink to 

another page "AddToCart.aspx" that attaches the ISBN as a querystring for 

further processing.  I am using the following code for the hyperlink 

column:



      <ASP:HyperlinkColumn HeaderText="<b>Book Title</b>" 

DataNavigateURLField="Title" DataNavigateURLFormatString="AddToCart.aspx?

productID=<%# Container.DataItem('ISBN') %>" DataTextField="Title"/>



Instead of binding the ISNB, the link is coming out:



AddToCart.aspx?productID=<%# Container.DataItem('ISBN') %>



I have used the Page.Databind() and all of the other fields have bound 

properly, so i am not sure why I am having this problem.  Any help would 

be greatly appreciated.  Thanks.

Try...

<ASP:HyperlinkColumn

  HeaderText="<b>Book Title</b>"

  DataNavigateURLField="ISBN"

  DataNavigateURLFormatString="AddToCart.aspx?productID={0}"

  DataTextField="Title" />



The difference is the use of the placeholder "{0}" tag within the

DataNavigateURLFormatString.  The placeholder will be filled with the

value specified in DataNavigateURLField during databinding.

Hugh,



Try:



<ASP:HYPERLINKCOLUMN datatextfield="Facility"

	DataTextField="Title"

	DataNavigateURLField="ISBN"

	DataNavigateURLFormatString="AddToCart.aspx?productID={0}" />





Now, assuming the DataTable in the DataSet you are binding to the DataGrid

has an ISBN, the URL should come out:



AddToCart.aspx?productID=524724627647432



or whatever the ISBN # is ...



Hope that helped ...

Thanks Dan.  This was very helpful.  Should I assume that you can only 

bind one querystring value based on the placeholder?

You can bind as many columns as you want using this sytax



DataNavigateURLFormatString="<%# "AddToCart.aspx?productID=" +

Container.DataItem('ISBN') %>"
