Error Passing Parameter To Rad Window

[Tracy]

Hi,

I am opening a rad window from code behind on a button click.   The rad window is used to display the contents of a multi-line text box.  I pass 3 parameters, strErrorId, strFieldName and strFieldValue,  to the window and usually it works fine.  But ,I get the error ' ...is not a valid virtural path' when one of the parameters passed to the window contains the name of an aspx page or is stored with multiple lines.

Does anyone know how I can pass these type of parameters correctly?

Thank you for your help.

For Example:
If the strFieldValue parameter is http://localhost:54807/WebForm6.aspx then I get the error
~/Modules/Central/WBF CTL Large Field Display.aspx?&ErrorId=216ad1a1-d3b8-4ef0-b70d-c4b1b44fa0d8&FieldName=HTTP Reference&FieldValue=http://localhost:54807/WebForm6.aspx' is not a valid virtual path.

If the strFieldValue parameter is Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; InfoPath.2; .NET4.0C; .NET4.0E) then I do not get the error.

If the strFieldValue parameter is the following I also get the error.

Below is the code I am using to open the rad widnow

Public Sub ShowFieldDescription(ByVal sender As Object, ByVal e As EventArgs)
       Dim ibtDescription As ImageButton = DirectCast(sender, ImageButton)
       Dim frvView As FormView = DirectCast(ibtDescription.NamingContainer, FormView)
       Dim strFieldName As String = ibtDescription.AlternateText.ToString
       Dim strErrorId As String = DirectCast(frvView.FindControl("ErrorId"), Label).Text
       Dim txtField As TextBox
       Dim strFieldValue As String = ""
       Select Case strFieldName
           Case "Error Description"
               txtField = DirectCast(frvView.FindControl("ErrorDescription"), TextBox)
           Case "Error Comments"
               txtField = DirectCast(frvView.FindControl("ErrorComments"), TextBox)
           Case "HTTP Reference"
               txtField = DirectCast(frvView.FindControl("SourceHTTPReference"), TextBox)
           Case "Form Data"
               txtField = DirectCast(frvView.FindControl("SourceFormData"), TextBox)
           Case "All HTTP Headers"
               txtField = DirectCast(frvView.FindControl("SourceAllHTTPHeaders"), TextBox)
           Case "HTTP User Agent"
               txtField = DirectCast(frvView.FindControl("SourceHTTPUserAgent"), TextBox)
       End Select
       strFieldValue = txtField.Text.ToString
       Dim rwdFieldDisplay As New RadWindow
       Dim strNavigation As String = "~/Modules/Central/WBF CTL Large Field Display.aspx?&ErrorId=" + strErrorId + "&FieldName=" + strFieldName + "&FieldValue=" + strFieldValue
       rwdFieldDisplay.ID = "rwdDisplay"
       rwdFieldDisplay.NavigateUrl = strNavigation
       rwdFieldDisplay.Skin = "Black"
       rwmFieldDescription.Windows.Add(rwdFieldDisplay)

Hello Tracy,

This error is not directly related to the RadWindow control - you will get the same behavior if you try to assign this Url to any other similar component.
I see 2 problems in the query string:

1. The first argument (ErrorId) should be passed directly after the "?" symbol - you need to use "&" only for the rest of the arguments.
2. The main problem which causes the error is that you need to UrlEncode the field value. More information on that subject is available in various places on the Net - for example you can check the MSDN library.

I hope this helps.
Kind regards,

Thank you Georgi I will look at the URLEncode Method.
