VS 2008 TabControl - Position Of New Button Column
Jul 28, 2009
I have one form with one tabControl with two tabs, in each one I have one dgv, in the visible change event I create and add a new button column, that will be placed at the end. Now the "problem", if the first tab it's selected when the form becomes visible, the column it's placed in the correct position (last), and in the second tab the column it's placed in the third position.
If I do this with the second tab selected when the form become visible, the column it's placed correctly in this one, and in the third position in the first one... The code that I use, it's very simple, every datagrid it's bounded to a datatable, I tried the add method, then I tried the insert method, then I manually set the display index for each column, and none of this options solved my problem...

I am currently working on an OOP assignment based on vehicles as classes. The classes, attributes and object lists have been completed so far. In my main menu form, I have a tabControl from which each page displays is related to each class. Within each page, labels are included displaying attributes of the first related object in the list. There are also two buttons in each page for scrolling between each listed object from the same class. I want these forward/back buttons to be able to retrieve attributes from the next object in the object list and have them displayed in their relevant labels.

I have a vb.net windows forms project with a tabcontrol. Anyone know how to change the style of the tabpage title or "button" when you hover over it with the pointer ?
I guess you can change the colours with: TabControl1.SelectedTab.BackColor = Color.Black
But not sure how to hook up the mouseover to the hovered over tab title/button.

I'm in the proccess of creating an XML editor nothing fancy for a project I'm working on!
I got the idea of using the tab control to host multiple Richtexbox controls, nothing fancy.
I got the idea from Visual studio(2010) that it would be nice to have a close tab button, on the tab, but I can on get it to display on the tab
Code:
Dim CurrentTab As TabPage = TabControl1.TabPages(e.Index)
Dim ItemRect As Rectangle = TabControl1.GetTabRect(e.Index)
If CurrentTab.Controls.Contains(mButton) = False Then
[Code].....
I know it adds it to the Tabpage but I cannot find anyway to add to the tab itself, even though the text on the tab is using ItemRect!
Are the tabs themselves hidden like columnls are on other controls!

I have a tab control that I would like to set the background image of each button's interface to the same image. I set the color to transparency and set the background image, but the background image only works on one button's interface.

I have a form and in that form is a datagridview listing information from a table in a database. The datagrid is setup as read only and the user is unable to move the columns around. The purpose of the datagrid is to allow the user to select entire records and press a menu button that does some action on them. To make it easier to use the very first column in an unbound data column that I fill with a number representing the row count so 1,2,3,4.... this makes it easier for the user to count how many rows he has selected.
The problem is that the unbound column moves to the last column in the datagrid at random times.This only happens in development not after the application has been deployed. Its annoying because lets say I go in to add a label or change a menu item on the form that has nothing to do with the datagrid I have to make sure that the unbound column hasn't moved.Has anyone else had this problem mixing bound and unbound columns in a datagridview.

This problem has been perplexing me for some time now and I've tried various methods of implementing this but all have failed or have been very messy. There must be a recognised way of doing this On a form I have a treeview and listview control. The treeview allows a user to select a node and the listview shows the items within the node - pretty standard stuff. The possible columns (or subitems) list for each item in the listview is big (20 different columns in total). Some users will want to show certain information whilst others won't. Users will also want to customise column location and widths.
Implementing the customer location and widths is easy enough using standard My.Settings variables to store and retrieve the information. The problem is allowing the user to select which columns they want to be visible at any given time whilst still allowing for access to the relevant subitems.
The only method I know to achieve this currently is to set Column.Width = 0. This is not a good solution because the user simply extends the column out again from the user interface. I need to hide the column properly.I've been told that using a repository cache is the way to do this. Unfortunately the person didn't describe this properly and so I'm still stuck at sqaure one. My database access is achieved using Linq to Sql.

I have a listbox on my form which gets items added as the program progresses, when there are more items than the box can display, the vertical scrollbar appears, fine... so far so good.I would like the scrollbar default position to be at the bottom of it's column so that the last entered item is displayed but can't find the relevant command, I assume there is such a command.

Here's the issue in a nutshell (I can elaborate if you feel it's needed). In a DataGridView I want to capture the value of the row's key column so that when the user clicks on a column header to sort the data, I can reposition to the row that was selected prior to the click. The problem is that the sorting itself, once it's done, fires the same events (RowEnter for example) that I used to determine my key value, so it sets my variable to a new value and now

I am using a button together with a mediaplayer. The button represents the media player currentPosition. (I know this is already a built in feature of the media player object but I need a much bigger display area.) It works as planned and allows the user to get or set the currentPosition. The only aspect I'm not happy with is its jerky movement as it jumps from pixel to pixel. I thought I had solved the problem by using a PointF (MyButton.Left = MyPointF.X) only to discover that the MyButton.Left value is reconverted to an integer (i.e. a position in pixels).
Is there any way that objects like buttons can be positioned accurately using units of less than one pixel?
If not, is there any other kind of object that can be positioned more accurately than a button?

I would like to make data binding using BindingSource whereby whenever either Next Button or Previous Button is click the BindingSource position will change to display the data at that position.
I know that if I want use a loop of the BindingSource I could do somthing like vb code below but I am not sure if of binding it seperately. I usually bind it through the properties but this I cant because is an image column which I want to bind and I have to us memorystream to display it to reduce memory usage, so I asign it to arrPic so that whenever the BindingSource position changes the image column will be asign to arrPic.
Dim MyRow as DataRowView
For Each MyRow In dtView
'only use non-repeating names
CurrentPicture = Trim(CStr((MyRow("FileName"))))
If CurrentPicture <> LastName Then
[Code]...
The BindingSource filter the picturenames and add to a listbox. One name may contain about 4 or more pictures so when you select a name from the listbox the bindingsource populate only the pictures have the selected name and you can navigate forward and backwards.All what I want is how to bind a column to a textbox or picturebox by code. I know if it is a dataset I can declare a datarow and bind anything to the columns.

I need to redraw a button in a button column in a DataGridView. Nothing to complicated other than I do not want the width to be as wide as the column width. To do so I am assuming that I have to create a custom button column object which inherits from the ButtonColum. Then I am assuming that I have to over-ride the Draw of the buttton itself.

I'm just not able to add a custom TabControl to my project. I have found a custom tabControl here: [URL]. The CustomTab consists out of 4 .vb files. Normally I would add a component (.dll or exe) to my project. I tried adding the 4 .vb files but unfortunately no CustomTabControl.
