Access Controls Inside A FormView From The Code Behind?
Dec 18, 2010
I have a checkbox and a panel inside of a FormView control, and I need to access them from the code behind in order to use the checkbox to determine whether or not the panel is visible. This is the code that I originally used, but since I put the controls inside of the FormView, it no longer works.
Protected Sub checkGenEd_CheckedChanged(ByVal sender As Object, _
ByVal e As System.EventArgs)
If checkGenEd.Checked = True Then
[Code]....
There aren't any errors anymore, but nothing happens when I click the checkbox. I think there needs to be some kind of event to trigger it but I don't know how you can put an event handler inside of an event handler.

VS 2008, SQL Server 2008:I have a formview that holds data about a test.Each test can have many people assigned to run the test.I have 1 table to hold JobNumber (Unique) with all associated data I have a 2nd table to hold JobNumber And AssignedToID to have records for each person assigned to the Job.Right now I have it set up so the user will choose as many AssignedToIDs as they want and it populates a list box. The list box is a bound control. Can I populate the 2nd table with the contents of the list box?On the update of the formview I could loop through the contents of the list box and update the data 1 by 1 but it will be a pain when users remove assignees.

I have a panel inside a formview that is supposed to become visible when a checkbox (also inside the formview) is checked. I am able to access the controls, but I'm not sure how to actually make it work. This is my codebehind so far, I know it's not right, but it gives a basic idea of what I'm trying to do.[code]

I've been building controls for many years professionally and personally, but even back in VB6 days I just could not work this out. After all this time I remembered about it again.If I create a usercontrol/containercontrol and add one or more controls to the controls surface, I just cannot figure out how to access the controls at design time.

I designed a form, set a tab index for the controls inside, but when I send "tab" from some, the focus not always go to the right one.
I mean:
textbox1 - tabindex = 1
textbox2 - tabindex = 2
textbox3 - tabindex = 3
button1 - tabindex = 4
I send a tab from textbox 2 and the focus go to the button, not to the txtbox3.

Let's say we have a composite web control with a combobox and a textbox. Is it possible to build into the control functionality such that when the text in the textbox changes, it posts back and adds the value as an option in the combobox?
I know that I could add an "onchange" handler to the textbox and make something work with Javascript, but that's not really what I'm looking to do. Is there a way to just put like:
CODE:
In the web control code and it connect to the TextChanged event of the textbox?

But I don't know if i posted this at the right place. I am making 40 textboxes inside a panel. And this textboxes I set it to visible=FALSE. Then I have another textbox named txtNoteam in which once the user will enter a number in this txtbox which is less than or equal to 40, those textboxes will be set to true starting from textbox1 to textbox40 depending on the number entered by the user. Example: user enters 3, then textbox 1 to textbox 3 will be set to visible.
I was successful in doing this except one thing, instead of textbox 1 to textbox 3 will be set to visible, it's the textbox 38 to textbox 40 will be set first. This means it will start from the last textbox to the first textbox instead of from textbox1 to the last textbox.
I need your help on what should I do for this to be able to set it to visible from the 1st textbox to the last textbox or is there any other ways of doing this?

I am trying to access controls that were added to the form and created code all before I added them to a panel. Upon form loading I create the form handle into a dictionary. then I call that dictionary ID and add data to the controls. I can't seem to add data to the controls inside the panel.. I think it is something simple. I may just be over looking the method I need to call.

We are developping an application VB.net 2.0 and SQL 2005. Users are allowed to cancel a reception based on a purchase which may contains many received goods. But, during the process of cancellation, some questions are asked to users such as "Do you want to cancel Good #1".
If yes, delete. Then, "Do you want to cancel Good #2", no, do not delete and one another question (if received item is issued, a process must be made manualy by the user). And, at the end, if all goods were successfully cancelled, we have to cancel the reception itself. But sometime, if an error occurs or some conditions occurs once asked to user in this process, we want to cancel any actions made from the beginning and make it back to his original state. So I thought about Transaction.

I've got 2 DataTemplates defined for a Listbox Control. 1 Template is for the UnSelected State and the other one is for the Selected State(showing more detail than the UnSelected State).[url]...
about how to access the Elements inside the DataTemplates from Code behind.
I get it right, but it only finds and returns an element of the UnSelected DataTemplate. But when i search for an element in the Selected DataTemplate i get a NullReferenceException.
