I believe we'll have to loop through all of the checkboxes and then check them. The problem, is that when declaring the variable, I'm not sure how to gather check boxes
For example:
Dim i As New ...
For Each i In Tabpage1
...
Next

I use check boxes and place them on my user interface (See attachment)I have coded the code for "select all" button :
Code:
Private Sub checkedall_Click(ByVal sender As System.Object, ByVal e As_
System.EventArgs) Handles checkedall.Click
Dim chkboxes, outs As New Collection()

I could not seems to check all the boxes. Is there something wrong with it? I am not sure how to assign array to check boxes.
I'm writing a program for my class, which pretty much is an energy cost calculator. It takes 4 inputs from 4 text boxes and multiplies them, and the result is the cost. Well, now I have to come up with a way to check for empty text boxes and display a prompt to enter a number. I've tried inserting multiple codes to display a prompt and to no avail nothing has worked, I also receive the error "when casting from a number, the value must be a number less than infinity" error.
View 3 RepliesFor example, I clicked the Add Text box button, so it added 3 text boxes in the form (I used Dynamic text box so it can add multiple text box). When I input data to one of those 3 text boxes and then Save button has been clicked. It should checked whether the dynamic text boxes are empty or not. If there are empty text boxes, then saving data to db should not be continued and display a message telling the user that empty field(s) are invalid.
In the code below, it saves the data even if there are empty text boxes and I think because it is in the for loop, it checks the text boxes one by one and repeatedly displays the message box that I coded.
Here's the complete code:

I am trying to check all the checkboxes on a webform (aspx) page, which is inside a master page,depending on the ID of the checkbox. The checkboxes are created dynamically, so I only know the prefix for finding it. So, I need to find these checkboxes by iterating the controls on the page somehow. It's not working out.

I've got a screen with 4 group box and several text box inside them.Each group box is controlled by a check box, so if the check box is true, the group box is enabled. Otherwise, the group box will be disabled.So far, I've been using a 'Refresh' button to evaluate the check boxes values.Now I'd like to give up using that button, so if when I change the check box state, so will do the group box. How could I do that?

View 4 RepliesI have a Form with a Group Box with a number of check boxes within it, each check box has a text box next to it for the user to enter a number.

View 2 RepliesUsing Studio/VB 2010 here and would like to find out how to approach the following. Examples would also be welcomed as I've not yet tried the progress bar control.
Scenario: A windows form will contain multiple check box controls that will be "auto-checked" as other parts of the user application/interface are completed. I would like to show a progress bar on the form that will give the viewer some idea of what has been completed. For example, 5 of 20 checked-off would show 25% in the progress bar.
I call .show() and .hide() on a form and then I want to determine the current state. I've been checking .visible to determine if the form is visible, but I've stumbled uppon a problem. My form is being rendered inside a SplitContainer which I collapse each time I hide the form. So, by logic once I hide the form with .hide() it is no longer visible, and since I have collapsed it's container, even if I call .show() it would still NOT be visible couse it's container is closed.
So, how can I simply check if .show() has been called rather than checking if the form is visible.
The final goal is to show() / hide() the form along with collapsing / un-collapsing the container.
P.S.: I know I could simply check the container and show the form accordingly, but my form also supports detaching from the container, so that wont work for me.
