Hello, I created a form which is built mostly with ordered lists: http://www.27lamps.com/public/Beta.htm I am having a few problems. All of them inside a DIV to which I am applying the class "ListBox" 1. ListBox is not being applied to the child tags of that DIV, i.e., OL and LI. They have the styles defined by parent class. How can I solve this? 2. My second problem is how to clear floats on my ol. I applied the overflow approach to my OL tag but this does not seem to work. Note that I am trying to display 3 LI per row simulating a table. Could someone, please, help me out? And I am open to any suggestion which might improve my CSS on this form. I have been working on this for quite a while but I know I can still improve it. Thank You, Miguel

Hello, I have created a GridView on runtime by implementing the ITemplate class. This Gridview displays a list of articles. Each article has a Title, Content and PubDate. I am trying to create a Date Header like in a blog, i.e., display the date on top of every daily posts. For example: Wednesday, 25 of April of 2007 Article 3 (PubDate: 25.04.2007 # 20:15) Article 2 (PubDate: 25.04.2007 # 11:30) Article 1 (PubDate: 25.04.2007 # 08:40) Wednesday, 24 of April of 2007 Article 2 (PubDate: 24.04.2007 # 21:32) Article 1 (PubDate: 24.04.2007 # 15:45) How can I created the date header as I described? Thanks, Miguel

Hello, I have an ASP.NET page and in its runtime code I am trying to get an user profile, change it and save it. It works if I use Profile, which is the profile for the current authenticated user. But I want to change the profile of another user. Anyway, I am using: 1 Dim pcProfile As ProfileCommon = CType(ProfileCommon.Create(Username), ProfileCommon) 2 3 ' Update personal 4 With pcProfile.Personal 5 .Blog = tbBlog.Text 6 .Homepage = tbHomepage.Text 7 .Name = tbName.Text 8 End With 9 10 pcProfile.Save() This is not working. What am I doing wrong? Thanks, Miguel

Hello, I have a generic list named Rows: Dim a As New Generic.List(Of Row) Row is a structure which has 2 properties: Name and Content. Is it possible, without a for loop, to find a Row in Rows which Name is "Home" and get its content? Thanks, Miguel

Hello, I created 2 GridViews, A and B. I created 2 datasets from Asp.Net 2.0 profile data. Each GridView has a Bound Field and a Button Field. When a button on GridView A is clicked the following should happen: 1. Copy the Row to GridView B 2. Delete the Row from GridView A Finally, I have a button which would get the data from GridView A and GridView B. What is the best way to create this? And is GridView the best way to do this? Thanks, Miguel

Hello, I need to pass to a function a list of pairs of values. For each item the first value is a string and the second value is an Enum named Country. For example, consider I need to pass 3 items: "New York", Country.UnitedStates "Paris", Country.France "London", Country.England What data type should I use create this? And how can I access each item inside my function? Thanks, Miguel

Hello, I created the following SQL script to check if a record exists: IF (EXISTS (SELECT LevelName FROM dbo.by27_Levels WHERE LOWER(@LevelName) = LOWER(LevelName))) Return (1) ELSE Return (0) And I also found in a web page another solution: IF EXISTS(SELECT 1 FROM TABLENAME WHERE LevelName=@LevelName) SELECT 1 ELSE SELECT 0 - Which approach should I use? - Why "SELECT 1 FROM"? - And when should I use SELECT or RETURN? All I need is to know if the record exists ... nothing else. I will use this procedure on an ASP.NET 2.0 / C# web site. I am not sure if this important but anyway ... Thank You, Miguel

Hi, To be honest I am not able to debug and see what is inside container.DataItem("Name"). However, in the code I posted I have the function which creates the DataTable: Public Shared Function Collaborators() As DataTable ' Create collaborators data table Dim dtCollaborators As New DataTable ' Add columns to collaborators data table With dtCollaborators.Columns .Add(New DataColumn("Name", GetType(String))) .Add(New DataColumn("Mobile", GetType(String))) .Add(New DataColumn("Email", GetType(String))) .Add(New DataColumn("City", GetType(String))) End With ' Create and add a new collaborator row Dim drRow01 As DataRow drRow01 = dtCollaborators.NewRow ' Define collaborator row values drRow01("Name") = "John" drRow01("Mobile") = "983498223" drRow01("Email") = "john@mydomain.com" drRow01("City") = "New York" ' Add row to collaborators data table dtCollaborators.Rows.Add(drRow01) ' Create and add a new collaborator row Dim drRow02 As DataRow drRow02 = dtCollaborators.NewRow ' Define collaborator row values drRow02("Name") = "Andrew" drRow02("Mobile") = "983498223" drRow02("Email") = "andrew@mydomain.com" drRow02("City") = "Paris" ' Add row to collaborators data table dtCollaborators.Rows.Add(drRow02) ' Return collaborators data table Return dtCollaborators End Function ' Collaborators It seems ok, right? What should I do? How can I see what is inside container.DataItem("Name") as you mentioned? Thank You, Miguel

Hi, I read carefully what you wrote and I got the same error after making a few changes to my code. This is what I did: ' InstantiateIn Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn ' Define template container Dim tcCollaborator As ComponentArt.Web.UI.GridServerTemplateContainer = CType(container, ComponentArt.Web.UI.GridServerTemplateContainer) ' Add lCollaborator data binding handler AddHandler lCollaborator.DataBinding, AddressOf lCollaborator_DataBinding ' Add item template child controls container.Controls.Add(lCollaborator) End Sub ' InstantiateIn ' lCollaborator_DataBinding Private Sub lCollaborator_DataBinding(ByVal sender As Object, ByVal e As System.EventArgs) ' Create and define lCollaborator Dim lCollaborator As Label = CType(sender, Label) ' Create and define lNews container Dim container As ComponentArt.Web.UI.GridServerTemplateContainer = CType(lCollaborator.NamingContainer, ComponentArt.Web.UI.GridServerTemplateContainer) ' Define lCollaborator text lCollaborator.Text = "Name: " & container.DataItem("Name").ToString End Sub ' lCollaborator_DataBinding Any idea? I am completely out of ideas ... Thanks, Miguel

Hi, sure. I just debugged and I get an error in the following line: lCollaborator.Text = "Name: " & tcCollaborator.DataItem("Name").ToString I though it was because of tcCollaborator.DataItem("Name").ToString But now I replaced this line by the following and I don't get any error: Dim a As String = tcCollaborator.DataItem("Name") Of course I don't see anything in my grid. Now I am confused. :-( Any idea? Thanks, Miguel

Hello, I am trying to create a ItemTemplate at runtime for a ComponentArt Grid. This GridView works in a very similar way to the Asp.Net 2.0 GridView so the implementation method should be the same. When I don't use the ItemTemplate everything works fine. However, when I use the ItemTemplate I get the following error: "Exception Details: System.NullReferenceException: Object reference not set to an instance of an object." On the code line lCollaborator.Text = tcCollaborator.DataItem("Name").ToString & tcCollaborator.DataItem("City").ToString I think my problem is really the binding method. Could someone please tell me what might be wrong? I also tried using the Asp.Net 2.0 GridView and I am getting the same problems. I post my VB.NET code. Please, fell free to answer in VB.NET or C#.

Hello, I have the following: ' Loop through each color enumeration name For Each color As Color In [Enum].GetNames(GetType(Color)) Dim name As String = MyF(color, Thread.CurrentThread.CurrentCulture) Dim index As Integer = CType(color, Enumeration.District) Response.Write("Name: " & name & " | Index: " & index.ToString & "
") Next I think this is working but I am not sure if this is the best way to solve this. Note: MyF is a function with a Select Case block which returns a string giving a enum element and a culture. I need this. However, I now need to get the text of an element by giving its index. For example, get "Red" when I say 1. Could someone help me out? Thanks, Miguel

Hello, I am creating a web site with Nested Master pages. I also need to have a class where the culture is set. When the culture is changed by the user the page refreshes and the change takes effect. I saw this approach, I think, on a MSDN web site or blog: Config.vb > Class where culture is set from profile value _Base.master > Parent master page ( _Navigation > Child master page) Default.aspx.vb > Page I have this working without the child master page _Navigation.
