I have a project where I need to add TabPages to a TabControl. I have a Panel with 10 checkboxes on it and I want to replicate that onto each TabPage as it is added.What I get is it is added to the first page, then when I add a second tabpage, the panel is moved there and not replicationed even though I used the (Add) method.
View 1 RepliesI have a program that allows the user to add steps to a process (tabpages in a control). All tabpages are generated on the fly by duplicating a "template" tabpage and consequently have the same control names such as textboxStepDesc. Here is the hierarchy of the controls to get to textboxStepDesc. Both TabPage1 and TabPage2 are in TabControl1
TabPage1
Panel1
textboxStepDesc
other fields
[code]....
Since textboxStepDesc exists in Panel1 in both TabPage1 and TabPage2, how do I specify that I want to retrieve the value of textboxStepDesc.text on tabpage2 vs. textboxStepDesc.text on tabpage1?
Now my idea was to have a tablelayoutpanel with labels in it,Functionally my TabControl allows the user to sequentially select various components used for designing a machine, My idea was to provide him an overview of his previously selected components at every tab.
View 2 RepliesI've hit a roadblock and really need help with looping through tabconrol's tabpage's, getting each tabpage's parent name and richtextbox control's text value. I have a ctabcontrol that has ctabpage tabpages, which also have Usercontrol's on the body of each tab. I developed a FindAll to search through each openned tabpage's richtextbox in the mdi parent container form. However, I cannot get the for loop to produce any values for the controls. All values are 0. The richtextbox.text value is empty. I even tried to produce a value with TabControlCollection to no avail, it shows 0 tabs in the collection even though I have 3 tabs open in the mdi parent container. How can I get the actual controls and values from other tabs so I can evaluate them in my Find tabpage functons?

I'm making a custom TabControl duplicate and I can't seem to be able to add controls to its TabPages. In fact, they don't show up at all! I've got code that sets their BackColors to Red, and their DockStyle is set to fill, but they just don't show up. Here's my code for the CustomTabControl:
Public Class CustomTabControl
Inherits Control
Private Const TAB_HEIGHT As Integer = 32

How can I drag controls within tabControls/Pages without losing handlers for buttons etc.?Cut and Paste looses all handlers?
View 1 RepliesWhen a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).
I am trying to print multiple tabpages each as its own page. The problem that I am running into is that it will only show the last page loaded in the print preview.

I've tried hiding one tabpage in the form and it was somehow successful. However, it was not the one i'm planning to do with my program. I don't know if there exists any code that could make the tabpages(two actually) automatically hide when the form loads and would only be visible after some passing some conditions.

View 1 RepliesIn VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?

View 6 RepliesSo I have 2 picture boxes, a textbox, and a button. One of the picture boxes adds another row with the same controls but moved down when clicked and the other picture box (should) remove the same row that it was clicked on. I have PictureBoxAdd1, PictureBoxRemove1, TextBox1, and Button1 set up by default and when PictureBoxAdd1 is clicked, it adds 1 at the end of the name properties. Now, how do I remove the appropriate row when PictureBoxRemove is clicked? Say I have 5 rows (but the amount of rows available will depend on how many PictureBoxAdd was clicked), if I click on PictureBoxRemove4, then PictureBoxAdd4, PictureBoxRemove4, TextBox4, and Button4 should be removed all together.

I am working on a project for a handheld in Visual Studio 2008 where I need to add a group of labels to a panel that correspond to a record on the database. The record is a "Pass/Fail" Record. So, if the record is a "Fail", the failed items will be added below the main group of labels; therefore, many child groups of labels will be added below the main group, which is theoretically the header record. I am using a second panel to add the failed items. My issue is how to dynamically add, name, and position the failed item labels and panels. Below, I have included a sample of what I am trying to accomplish.

The goal of this code is to add a control to a panel in runtime. This MUST be done in runtime for the purpose I intend. The problem is that, when I add a second control, the first one disappears.
