How To Place ASP Custom Controls In Separate Tab Panels
Dec 23, 2011
I have a asp.net placeholder which gets populated with many custom controls, each custom control is a summary of a location containing various facts and interactions. When directly populating the placeholder with the controls they get added one under another down the page. I'm trying to find a way to place each custom control generated in a loop in its own tab (any sort of tab, asp.net/jquery ui etc) so that the user can select the summary they wish to view instead of having to scroll down the page to find it. (I'm using ASP.NET and VB.NET)

I am familer with looping thru controls like so:
[Code]....
Next I have some labels on another form, that due to the design can't be in seperate panels. They are (lblChipColor1 - 6) and (lblChipValue1 - 7). I am trying to populate the color ones from the Array above. I can obviously loop thru the array, but I can't find a decent way to loop thru just the lblChipColorx lables ignoring the lblChipValue1x labels. It would be easy if they were on seperate panels. I tried adding the labels names to an array of type string and of type label, but got nowhere with that. Is there another way to group them, or build const array of label names, that I can work with?

I wrote an application using VB.Net 2008 (Not express edition) and in my main form I have several of it panecontrols and on these panels I have lots of other panels that contain controls.My problem is when I switch between the main (split panels) the controls are flicks(flashes) like they draw themselves for a second or two and after that the form is displayed as it should be

I need transparent panels. I simply set that background color of controls to Transparent - this does not solve the problem, as the transparency simply shows the background color of the form, but does NOT show any controls placed on the form, which is the crux of my problem.Why? Because I'm trying to use this skinning example, which does the skin by creating a user control, and make the panels show the skin's background:[URL] It seems I'm going to have to override the panel and paint it's background manually, but I don't understand how it all works; I've created a new class and overridden the panel, but the painting stuff is way above my head.
In the form's class:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Panel1.BackColor = Color.FromArgb(0, 0, 0, 0)
'supposedly a trick to make a gradient background on the form

I'm working on an menu program right now which has 20 panels used to display bmps that can be clicked on to select things. These panels are simply named something like pnl01, pnl02, etc. to pnl20. I'd like to make them into an array, like pnl(0) through pnl(19), so i can change the bmp on different panels like this:
x = 7
pnl(x).backgroundimage = image.fromfile(file)
i thought this had something to do with enumerated controls but after some searching i couldn't figure out if i was looking for the right thing.

I'm trying to make custom ListBox with some graphics. Base is ItemCollection - each item contains Panel, 2x label and 2x picturebox. What each panel have to do:
- Change backcolor on MouseEnter and set color back when MouseLeave occurs.
- On MouseDown(LMB) - Panel stays "selected" - different color.
Problem: I can't access multiple panels at a time(and I need to), just one via sender as in function. Of course, I can do it hacky way, but I want to do it effective and regular. Is ItemCollection the right solution or should I do it just like an array of panels? Also I want them in one "box", ItemCollection is good for it.
Second "problem": I need to make labels "merged" in panels, when i MouseEnter them(labels), background color on that panel sets to my default color. when i MouseClick them(labels), nothing happens (need to "select" parent panel). It can be again fixed with hacky way, just disable labels - but then the colors of labels are unchangeable.

I wrote a class, StyledForm that inherits from Form.
StyledForm draws a styled titlebar, ect. However, in the designer you can place a control over the titlebar (because it isn't actually the form).
In a normal form if you place a control in the same spot, the titlebar (or form edges) would draw over the control, and the control wouldn't receive input there.

I am a bit lost in concept how to implement what i want to do. I have a gridview, a checkboxlist. I bind the gridview on the page_load. Everytime user choose a checkboxlist, the gridview rebind as well. I have something like this now. This is not the actual code. Thanks so much.
[Code]....
So what do i put here in order to allow paging ? basically, I have 2 datatables in the above example. In the actual code, I have about 5 datatables with 4 checkboxlists. I can't use Datasource control. I need to do it in codebehind as all code already exists.

I have an ASP.NET Web Site I am creating in Visual Web Developer 2008 Express using Visual Basic as the language. It is actually a rewrite-with-mods of an existing ASP script and I'm trying to chew what I've bitten off. I created my page with a text box (txtOutput) on it and since the end product is very complex, and it's generally good practice to separate like functions, I have created 4 separate classes in the App_Code section. My main page is Sync.aspx and has a code file Sync.aspx.vb with it. One of my code files is SyncDatabases.vb and in it I have created
Public Class SyncDB
In that class I have created some routines such as
Public Function ReadMSDB(ByVal SQLString as string) as Boolean
In this routine I want to put information in my text box txtOutput on the main form (the default - Form1).
My problem is that if I try:
Form1.txtOutput.Text = "Hello world"
or just
txtOutput.Text = "Hello world"
it says Name 'Form1' (or 'txtOutput') is not declared. I am sure I am missing something simple but have no clue what it is. I assume it's the fact that the write command is in a file (class?) outside the file (class?) containing the page itself but I don't know how to address it properly.

VB.Net Windows forms feature controls that are often dragged from the toolbox onto the form. The code for the control goes right into the form. Usually this is great, but is it possible to write the code for a UI control (like a panel) into a separate file which can then be imported or otherwise included into the main Form Class?
Context (a.k.a. long version): I have a form with an unchanging column of navigation buttons on the left hand side. The rest of the form is taken up by different panels, which in turn have different controls of their own. Clicking the different buttons on the left should cause these different panels to appear (clicking button "A" brings up panel "A"; button "B" brings up panel "B", etc.), but the left-hand menu should stay unchanged.
I'm having a hard time implementing this design in an elegant way in VB.Net. If I make each panel a separate Form, I have to duplicate the code that builds the unchanging left-hand menu in every file, which is terrible. I tried using inherited forms so the separate panels would inherit the left-hand menu from a master form, but that means each click on the menu sprouts the new form in a new window, and although the left-hand menu is inherited, the menu that I clicked and the identical-looking menu in the new window are not the same objects in memory and have no knowledge of each other.
I just want one window with central content that changes based on what you click on the left-hand side. A solution to this would be for the panels to be just that - panels - and not separate forms as I'm currently doing it. But this gets messy organizationally because the code for all of the panels has to be in the one massive master file. Hence the short form of my question (see above): How can I code a panel in a separate file and then bring it into the fold of the main form?

I have designed a form in VB.NET. At design time I have placed two buttons on it. When I run it, the form size looks smaller and the buttons I have placed at the bottom are not visible. Also the alignment of the text and picture box is also different from what I set at design time. Computer at which I am running the form is using a different resolution.

I am wanting to populate a form with check boxes and labels on starting of the app. My idea is to store to locations on the form in a database. I am creating an app that would have check boxes and labels that the user could check off to store points for completed tasks. The tasks on the form could change so I want the form to change as the tasks are changes with out re-coding the app.I am using VB 2003. I have searched but couldn't find anything.

So I've created a custom ListView by inheriting it and overriding the OnDrawSubItem(). I can now draw icons in several of the columns. It's pretty nice! My question is, is there anyway to do this for the ListViewGroup? I'd like to place an icon just before the group text.

I am using Visual Web Developer 2008 Express and making a Webform. I want to arrange my labels and drop down listboxes in a table to keep them together on the form in a neatly manner. If I use the 'ToolBox' on the side and drag a HTML table to the workspace I get a nicely formatted table with 3 rows and 3 columns. And I can drag and drop my labels/listboxes into these columns and all is fine and good.
If I use the 'ToolBox' and drag a ASP.Net table to the workspace it starts as just a boarder with '###' inside of it, which I cannot drap and drop controls into. I'm not sure how to place controls into it. I figured out that you can add the Rows - then Columns in the properties window, but that just adds more cells which have the '###' in them. I can make it work with the HTML table, but I just want to know if I can do the same with the ASP.net table.

in VB.NET i have 2 custom controls, one is a TextBox and second one is a ComboBox.These have custom values like Bool _IsHidden and are added on runtime to a form.Now, at some point in the code I want to check if the _IsHidden is set to True or False and display that information. Since the user can edit this values when creating the control these are not set on creation.
So what I tried is:(all of this is on MDI Forms)
For Each frm as CustomForm in Main.MdiChildren If frm.MyName = calledBy Then 'this part is just to know which form called the form to create the object For Each cntrl as CustomTextBox in frm.Controls'DO Something
Next End if Next
Now.. if the first control is a custom ComboBox it thorws an error since it sees that it does not match the custom TextBox control..how do i get around this? By my understanding it should just go through all of the controls on the said form and just check those who match CustomTextBox control ?

I've created custom buttons in a .dll and they work fine, so I thought I'd have a go at creating my own sort of listbox to replace the standard one in my applications. It's basically a panel with a few labels and a button (eliminating the need to select an item in standard listbox then click a seperate button). I want to add these panels to a panel on a form, at run-time, based on rows in a db.
If I try adding any arguments in the New() section of the class file it won't let me use the panel in my toolbox. Is there a way to pass arguments to custom controls, I need a new custom panel for each row in a db so need to pass an id to it to specify records; or even load the records in my application and create a new panel for each record, using info passed to it to fill in the labels on it. Or can I create the panel at run-time and refer to labels within the custom controls, setting their .text properties that way?

I would like to expand my knowledge of VB.NET and was looking at creating custom user interfaces or custom controls. The type of things I am thinking of is: [URL]s. How are those controls created? I imagine it involves using the existing controls in Visual Studio as a starting point, and altering them to suit your design?

I'm not going to post my code for my transparentlistbox class, but here is a link to it.It's been working fine as is, until early this morning when I tried to set a different size.[URl]..For the longest time I placed a normal listbox control on a form and resized that, setting a new public variable of transparentlistbox to the same size/location as the original listbox, setting the visibility of the original to false, and adding the transparentlistbox to the form (me.controls.add).It looked like this:
[Code]...
Now, since I've moved some buttons around on my main form, I resized the original listbox control to be wider (same height though). When I tested, the transparentlistbox (code didn't change still set to original listbox size/location), the size was that of what I had the original listbox set to, before resizing?
So, I commented out all of the custom drawing/paint events/etc I could find for the transparentlistbox and tested, still stuck to the original size. I stepped line by line debugging and verified that transparentlistbox1.size=listbox1.size indeed matched the new resized size (but didn't actually resize)?
Last I did was comment out the transparentlistbox.visible and put back the listbox1.visible and listbox1 does indeed show with the new resized size? I'm not quite sure what to test next?
