DataBind with HyperLink Column

[Robert]

Hi,

I'm beginning to use RadGrid with a LinqDataSource. The binding of the grid works just fine. Now I want to insert a hyperlink-column into the grid which displays the name of a user and when it's clicked the user's profile page is displayed.

In my aspx file I added the column like this:

<telerik:GridHyperLinkColumn DataTextField="aspnet_User.UserName" HeaderText="User" DataNavigateUrlFields="http://google.de"

                    SortExpression="aspnet_User" UniqueName="aspnet_User">

 </telerik:GridHyperLinkColumn>

Now, the problem is, that there is no text displayed in the grid. It seems that

the DataTextField property is not working (but it is working in a GridBoundColumn).

Another problem is, how to prepare the NavigateUrl property to use the userId.

Edit: I tried to add the GridHyperLinkColumn Programmatically via the RadGrid_ItemDataBound() evend handler but it seems that the handler never

gets called.

Thanks in advance for any hints.

Best regards,

Robert

Hi Robert,

Try setting the DataNavigateUrlFormatString property for the HyperLinkColumn as shown below.

ASPX:

<telerik:GridHyperLinkColumn DataNavigateUrlFields="CustomerID"  DataNavigateUrlFormatString="http://www.google.de/search?hl=en&amp;q={0}" DataTextField="CustomerID" HeaderText="CustomerID" UniqueName="CustomerID">
                    </telerik:GridHyperLinkColumn>

You can also go through the following online demo to get details about the column types supported by RadGrid.

Hi Shinu,

thank you for your hint. I already read the column types page. The code

which you posted does indeed display the hyperlink. Unfortunatly it doesn't

display anything (the line at the bottom of the grid cell is also not drawn) as

soon as I put the following in the DataTextField property:

DataTextField="aspnet_User.UserName"

When I use the same data binding with a GridBoundColumn instad of a GridHyperLinkColumn it works perfectly and displays the user name.

Best regards,

Robert

Hi Robert,

I noticed that you are setting the sort expression to
SortExpression="aspnet_User"  . Instead  try setting it to
SortExpression="aspnet_User.UserName"

Thanks,
