Re: Dynamically remove multiple innstances of child form from parent form

Loop through the controls of Form2, and check their type. if it is a form, close it. Shouldn't be harder then closing all types of control y within control x.

Force a Tab

I have tried to search for an answer on line but maybe my search choices are worded wrong. I have a form that has multiple text boxes. (Just like many forms) I am using a barcode scanner to input data into the textboxes. I put a enter post amble in the scanner to go to the next field, and it works. The form gives the user the ability to lock fields and keep those values in the textboxes for multiple iterations of the form entry. I lock textfields by changing enabled to false.

Issue: When I scan the text box previous to a locked textbox the cursor will not tab over the locked field. I do not want to put a tab in the scanner do to other issues on that page.

I want to know if there is a way to force a tab through code. Example: When the textbox is validated then force tab to tab to next unlocked textbox.

Thank you for any help you offer.

Check that your locked control has TabStop property set to false. That could be the reason if the focus goes to the locked control.

Also since you now the layout of your form, one way could be that you programmatically use SetFocus method on the control where you want to go.

I have tried the tabstop idea. It still does not work. I Need to know if there is a way to force a tab in code. If I can I think it will work. I want to try that before I write a bunch of code to change focus.

You can simulate tab with SendKeys, but I think it would be easier to call for example: Select Method[^].

When you say that it doesn't work, do you mean that the focus goes to the locked control even though it's TabStop is False or does tho focus go somewhere else?

It sounds like there is no set tab order, that you are figuring out at runtime.
I use this to enable/disable our controls tabstops,

''' <summary>
''' This sets the tab stops to false when in inquire mode and tab stops to true if in update mode.
''' </summary>
''' <param name="c">C is the control from the calling form</param>
''' <param name="bStatus">This sets the control tabstops to True (enabled) false (disabled)</param>
''' <remarks></remarks>
Public Sub sInitializeControls(ByVal c As Control, ByVal bStatus As Boolean)
    'This routine needs to be ran after a form is loaded
    'When we enable and disable controls the cursor will stop on the controls that have been disabled
    'This is a recursive function
    'c = Control from Calling form
    '
    Dim ctrl As Control
    For Each ctrl In c.Controls
        If String.Compare(ctrl.Name, "btnClose") = 0 Or String.Compare(ctrl.Name, "btnCancel") = 0 Then
            'exit
        Else
            ctrl.TabStop = bStatus
            If ctrl.HasChildren Then
                sInitializeControls(ctrl, bStatus)
            End If
        End If
    Next
End Sub

You might be able to modify this to your needs.
I would think you could call this to set all tab stops false and then in the validation routine you could set the specific control you are wanting to move to
like so
control.tabstop = true
control.focus() or control.select()I have found the latter of these two to be more reliable

I have tried changing the tab stop with no luck. So, are you saying there is no way to force a tab through code?

does the gotfocus/enter routine fire if you hit tab? if so, test if the control is disabled and then issue a

My.Computer.Keyboard.SendKeys("{TAB}")

Take a look at the Control.SelectNextControl method. It may be what you want.

This shouldn't even be an issue. How I did it in the past is enable the Form's KeyPreview, then handle it's KeyDown event. This handler should look for the preamble keysequence, eat the keys so they don't go to the controls, then start reading each key and appending to a string, until you see the postamble sequence, being sure to eat those keys. Then you've got the barcode, having never input the thing into a TextBox.

So, you have a string with much more in it because all you've shown is the table.

I'd probably use a Regular Expression to extract the table rather than use a StringBuilder. I don't think you can use a StringBuilder to find existing text, just manipulate the text.

The table will render properly if you send the mail as HTML. Not all clients support HTML though.

I have already tried using

Table2.InnerHtml but i get not supported exception. now my only question is
also I have tried using below
Dim SB As New StringBuilder()
Dim SW As New StringWriter(SB)
Dim htmlTW As New HtmlTextWriter(SW)
Table2.RenderControl(htmlTW)
Dim tbl As String = SB.ToString()
MailMsg.Body += tbl

but this doesnt gives me the dynamically generated records.

how do i get currently rendered html content via aspx page(please note contents of Table2 is generated dynamically) and how do i use regex to only copy Table2's content.

please help

What does it give you then? If the code runs correct, you should get the HTML as generated by "Table2". Does it?

I have already tried what is mentioned in the article.

This only gives what is already in TAble2 before rendering Table2 programatically. here is what TAble2 has before its rendered programatically

<TABLE id="Table2" cellSpacing="0" cellPadding="4" runat="server">
<TR >
<TD width="30%">Product Name:</TD>
<TD width="30%">Quantity:</TD>
<TD width="10%">UnitPrice:</TD>
<TD width="10%">Amount:</TD>
</TR>
</TABLE>

the scripts mentioned in the article only gives me above but not the end result. i.e additional rows that are created programatically.
could someone please help?

sorry this works fine. I think the postback was causing the programatically created data not being loaded

I did this before I do postback

cache("data") = RenderControls(Table2) --> this comes from one of the links you provided me.

and it Mailmsg.body +=cache("data")

Thanks very much

Here is another idea. If your HTML is actually XHTML (basically HTML that complies with the stricter rules governing XML) then you could load it into an XDocument (if you have .NET 3.5) or XmlDocument (for any version of .NET) and extract it using XPath, or navigating to the appropriate node and performing InnerXml (or OuterXml).
