    Hi,

    We have a hyperlink in the radgrid and unfortunately the filtering doesn't work.
    The following ASPX code have been used:

    <telerik:GridHyperLinkColumn HeaderText = "Discussion Name" DataTextField="Discussion_Name"
    ItemStyle-HorizontalAlign="Left" UniqueName="Discussion_Name"
    DataNavigateUrlFields="Discussion_Id" SortExpression="Discussion_Name" ItemStyle-Width="320"
    DataNavigateUrlFormatString="Observation.aspx?Id={0}">
    </telerik:GridHyperLinkColumn>

    Any ideas why is this?

    Thanks!

    Hello Debashis,

    In order the GridHyperLinkColumn filtering to work properly, you need to set the DataTextField as you already did. Can you elaborate on what happens when you try to filter it? You can add a GridBoundColumn with DataField the same you are using for the DataTextField for the GridHyperLinkColumn and see if it gives you the desired results upon filtering and if they are different.

    Kind regards,

    Same issue:

    <telerik:GridHyperLinkColumn SortExpression="Title" DataTextField="Title" DataNavigateUrlFields="ID" UniqueName="Title" DataNavigateUrlFormatString="~/Page.aspx?id={0}" HeaderText="Title"
            CurrentFilterFunction="Contains" ShowFilterIcon="false" AutoPostBackOnFilter="true" >
            </telerik:GridHyperLinkColumn>

    I can filter on all the other columns fine.  They all work where I type a search parameter and hit enter.  This then filters.  When I hit enter on the HyperLinkColumn I get nothing.

    Watching the Error Console I get this when I hit enter on a Hyper Link Column:

    Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

    Hello Jay,

    GridHyperLinkColumn filter on it's DataTextField and you should also have to set DataType in order to have correct filter working.

    ASPX:
    <telerik:GridHyperLinkColumn SortExpression="Title" DataTextField="Title"
       DataNavigateUrlFields="ID" UniqueName="Title"
       DataNavigateUrlFormatString="~/Page.aspx?id={0}" HeaderText="Title"
       CurrentFilterFunction="Contains" ShowFilterIcon="false" AutoPostBackOnFilter="true"
       DataType="System.String">
    </telerik:GridHyperLinkColumn>

    Thanks,
    Princy.

    I'm having the same problem, and setting the Datatype hasn't fixed it for me.  I can make a normal GridBound column pointing to the same data field, and it will work fine.  Any other ideas? :)

    <telerik:GridHyperLinkColumn DataTextField="RequestDisplayID" DataType="System.String"
        HeaderText="P. Requisition" UniqueName="RequestDisplayID" AutoPostBackOnFilter="true" ShowFilterIcon="false" CurrentFilterFunction="Contains"
        DataNavigateUrlFields="RequestID" DataNavigateUrlFormatString="Requests.aspx?ID={0}" SortExpression="RequestDisplayID" >
    </telerik:GridHyperLinkColumn>
