In the gridview I am trying to create a column where the user can see the tracking number of a package, click on it, and bring up a page with their package on it.  They can have tracking numbers from a couple different couriers.  The code below is not working.  Any Ideas?

<telerikGridView:GridViewDynamicHyperlinkColumn TargetName="_blank" SortMemberPath="TrackingNumber.TrackingNumberString" NavigateUrlFormatString="{Binding TrackingNumber.Courier.TrackingURL}" NavigateUrlMemberPaths="TrackingNumber.TrackingNumberString" DataMemberBinding="{Binding TrackingNumber.TrackingNumberString}" Header="Tracking Number" />

Hello Justin,

 Could you please share the values of a typical record? I would like to see how the following properties look like:

  • TrackingNumber.TrackingNumberString
  • TrackingNumber.Courier.TrackingURL
Also, how exactly does the code you provided 'not work'?

Greetings,

Hello Justin,

 Unfortunately, the way the DynamicHyperlink column works won't help you in your scenario. You can't have a varying format string. NavigateUrlFormatString is not event a Dependency Property.

What you can do to make your scenario work is use a regular Hyperlink column and apply a binding converter. You'll need to build the Uri in that binding converter and return it.

Please let me know if you need further assistance in this.

All the best,

Thanks for the Help.  Any chance I can get an example, or is there a demo on the site I can look at?  The current hyperlink column example is pretty basic.

Thanks again!
