Setting All Controls Inside A Panel To Visible?
Dec 30, 2009
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?

In my windows application I have a normal panel inside a flowlayoutpanel In this normal panel, i have some input controls(e.g. labels, textbox...) I have set the anchor properties thinking that it will auto-resize when I resize the window. But when i tested it, only the flowlayoutpanel auto-resize itself, as i can see that the sroll bar has moved further toward the right... the contorls in the normal panel didnt move at all.

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.

I've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!

I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

When 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'm getting some unexpected behavior with panel scrollbars, and was wondering if it is a bug, or simply something that I'm failing to do correctly. Basically, I have a panel with Autoscroll enabled. Then I put some other items inside the panel, and then make the panel smaller, so that the panel's scrollbars appear.
Outside of the panel I have 2 buttons, named "scrollOn" and "scrollOff", which turn the panel's scrollbar's on and off using the "Autoscroll" property (for example the "scrollOff" code I'm using is Panel1.AutoScroll = False ). So after I run the program, I move the panel's scrollbar down a little bit with the mouse (this part is necessary to reproduce the bug). I then click the "scrollOff" button (which should make the scrollbars disappear). But when I do that, the scrollbars are not only still visible, but they "freeze up" (can't move them with the mouse anymore).

I have set the panel on visible as false, so it would not show up when I run the form. I am trying to set the visible as true when I enter my mouse on panel location, but it doesn't show anything....
Private Sub Panel1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel1.Enter
Panel1.Visible = True
End Sub
How to set the panel visible as true when I enter my mouse on panel location while the visible are false?

I have a Windows Forms VB.NET application, with a panel that contains a few other controls.I set the panel's AutoScroll property to True, and that seems to appropiately apply the scroll bars when they are needed. The issue is that a user must scroll all the way to the right to access the verticle scroll bar. Is there a way to always show the verticle scrollbar no matter where the user is scrolled horizontally?

I am stumped on this one. I have a panel (pnlKeyPad) that won't change the visible property when I try to set it to True. But when I try to set the Dock Property to DockStyle.Fill it succeeds. I have tried them in different orders, setting the parent property to the splitpanel and nothing seems to fix it. The panel is on a splitpanel that is visible. The panel is set to visible = false by default.
Any ideas of why this panel won't switch to visible when I specifically set it to visible?[code]...

I have a simple treeview, when I click a node I want to be able to make a panel visible when a node is clicked using a simple if then statement and make the other panels associated with the other nodes invisible. From what I read the code should be placed in the afterselect method. Was thinking would be similiar to a list box using selected index or something but can't seem to get it to work.

I have a number of textboxes and labels in a panel which has to scroll in order to view them all. The user is then able to scroll down and click on one of the labels which has a textbox that appears so the user can change the corresponding value in the label. For some reason, if the user has to scroll down at all to any of the labels that are initially out of view, when they click on the label the textbox appears far below as if it was at its initial position and not directly where the label currently is.

I have aspx form with several textboxes.They are populated with values from a table via retrieval of a dataview.If the row count for the dataview is 0, then I'd like to reset the values in all textboxes. How can I loop through all the textboxes and set a default value?I've tried the following, but no sucess.
For Each ctrl As Control In Page.Form.Controls
If TypeOf ctrl Is WebControls.TextBox Then
CType(ctrl, WebControls.TextBox).Text = ""
End If
Next
My first For Loop was using Page.Controls but it returned only 1 count.The textboxes are inside a tabpanel (ajax), so do I have to locate the tabpage and then find all it's controls (for each tabpage)?

In 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?

I recently uninstalled an IDE for a motion control system (Delta Tau) that is a visual studio based product. Now when I bring up my Visual Basic 2008 IDE that I'm using to write an HMI for the control system, the properties for controls placed on forms doesn't appear in the properties window. And if I click on properties for a form I get the FileProperties2 information, not the form control properties such as size, location, or color. I am also not able to access the controls in the VB toolbox to place on a form. The controls are grayed out and unavailable. what part of Visual Studio 2008 got broke in the Delta Tau uninstall?
