View 1 RepliesI have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.
Dim x = GetType(List(Of )) 'valid statement
Dim list As New List(Of String)
Now I want to see if list is a List(Of T) variable: Dim isList = TypeOf list Is List(Of ) On the last line I get a compile error: "Type Expected". Is there any cheap-performance TypeOf operator alternative for generics?
I'm using DataGrid to populate the list, inside the DataGrid I'm trying to put DropDownList. I have the sample code in C#, then trying to convert to VB. But got error.
See the WORD with BOLD in VB. The error is "Operator '=' is not defined for types 'System.Type' and 'System.Type'."

I am trying to convert some old VB6 code to VB.NET. The VB6 uses a Canvas control, simply
Dim cv as Canvas
I cannot for the life of me figure out how to use the Canvas control in VB.NET (using VS2005). MSDN says it is in the System.Windows.Controls namespace, which doesn't seem to exist? All I see is System.Windows.Forms, which doesn't include the Canvas control.
My page has a DetailsView that has a hidden field in it that gets referenced by an SQLDataSource to populate a different field in the same DetailsView. I cannot get the codebehind to find the Control, no matter how many different ways I try. I really need to be able to show the TEXT field which is associated with the dsPicklist SqlDataSource. I have marked the code that is causing problems.
<asp:Label ID="Label1" runat="server" Text="Select Survey:"></asp:Label>
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
DataSourceID="dsSurvey" DataTextField="SurveyName" DataValueField="SurveyID">

I know the name is rigth cause I have printed the name in the create method and I have printed the name string in the code where I try to access it.
So by the looks of it it seems .Item() is not the right way to access the control.

View 4 RepliesI'm wanting to dynamically create some controls relative to controls already placed on the forum at design stage, how do I find the locations of the controls that are already placed?For example, I have a label called lblDateTime, its location is (13, 167) and its size is (65, 13).In my code, I want to place a new label below this label.I've tried to set the location and size properties of the new label using the location and size properties of lblDateTime.Size works, no problem, but the location of lblDateTime always returns as 0,0.[code]I want to set lblMessage DateTime. Location to (13, 180), but I'm actually setting it to (0, 13)What confuses me most is that Me.lblDateTime.Size is returning the correct values, so it's not like my code isn't finding the control.
