Could Not Find Control In ControlParameter
Jan 31, 2012
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">
</asp:DropDownList>

im tryin to link the 2 pages to each another, 1st, when i click on the View hyperlink in the product page, its supposed to lead me to the product view page, with the product chosen being displayed. Ive searched the net, and well, ive found some solution on this, but most of them were to update the statements, for my case it would be just to lead from the product page to the product view page. But everytime i press the view link, it leads to an error.
The source code is as below
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="productid"
DataSourceID="SqlDataSource1">

I'm building a live search inside our web application. But now i have a problem with a Web User Control where i can`t find a solution for.
I`m creating a User Control Search which later will be used for a default live search. Now i have created the solution inside a ASPX page without a user control. This works fine. But when i replace the code into a ASCX file (User Control) the input inside the textfield could not be found. No exception but the input of the function is nothing.
how to get the controlparameter or formparamter to work inside a user control? I already have tried things like ClientID this results into a exception (control not found). The fieldname with the $ instead of the _, this results into the input is nothing.

I working on a VB.NET project to manipulate a VB6 form using COM Interop. Some of the controls on my VB6 form are indexed and some not, so calling ctl.Index fails on those that have no index. Is there a way to work out if a control is indexed?

I 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.

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.

I have a simple gridview that contains a label in one of the rows. I'm trying to access that label in the RowDataBound event, but for some reason I keep getting a "Object reference not set to an instance of an object." error on the line where I am using FindControl.
I've tried using "gvQReport.FindControl", "e.Row.FindControl", and "Me.FindControl" but nothing works.

I've created a new tabpage and also added a richtextbox to it:
Private Sub AddTab(ByVal ctrl As TabControl, _
ByVal text As String)
If Me.InvokeRequired Then
[Code].....
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.
So how to access to dynamically created control?

I'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.

I have a DataList inside a DataList that causes my page to lose the controls. The page works and there are no errors, but my label is never found! This is odd because the label shows on the aspx page, it just doesn't remove the 2 items that I want it to remove. When debugging, it skips over the If statement altogether:
If lbl IsNot Nothing Then
If lbl.Text = "Self Directed" Or lbl.Text = "Systems" Then
lbl.Visible = False
[Code]....
This will only hide the text for "Systems", I have gone through each label in that particular question and each has hidden itself. This code does work on another page so I know that Self Directed is exactly how it is capitalized. I even copied and pasted from the database and it still wouldn't hide.

I'm an old Access developer and know VBA quite well, but now I'm working at learning VB.net. I'm trying to find the equivilent of the following Access VBA code using VB.net:
Function EvalField()
Dim x As Integer, ctl As Control
Set ctl = Screen.ActiveControl
x = Val(Mid(ctl.Name, 5))
Screen.ActiveForm.Controls("Formula" & x) = ctl
ctl = Eval(ctl)
UpdateTotal
End Function
This code sets a control variable to the currently active control, then copies the text from that control into it's matching "Formula" field for reference by the user), then turns the string of math into the answer. For example, if the user enters 5 + 4, that will be copied to the Formula textbox, then it will be evaluated and the answer will replace the 5 + 4. And lastly, the UpdateTotal sub will execute which will add this answer to the existing Total field.
