VS 2008 Position On A Row In DataGridView?
Jan 3, 2011
in my form, I have a DataGridView and TreeView apart from other controls. Now, the data shown in the DataGridView is also displayed in the TreeView. What I need doing is that when a node in the TreeView is selected, the corresponding row in the DataGridView needs getting selected for further action.I used some logic to determine the DataGridView row. But, I am unable to select the row. When I use the DataGridView.Row(index).Selected function, the row is selected, however, the row index does not change.

When i move the scroll bar the first two columns should not be disterb.Is there any property like Scroll bar position should be starts ??I tried the " FirstDisplayedScrollingColumnIndex" property but it only starts the Scrollbar from giving column index after moving the scrollbar the first two columns are moving into left side.

How can I get the position of a certain cell of a datagridview. To be specific I don't want the mouse coordinates. Suppose I have a datagridview with Name (ReadOnly), ID and TransDate columns and I want to popup a tiny lookup form when the mouse is clicked or Enter button is pressed when the focus is upon the Name column. The lookup form should openup exactly upon the Name column of the selected row.

I'm getting the error on the following line of code: dr(y) = ds.Tables("Original").Rows(y).Item(i)I got the piece of code from the following website: [URL]..I think it's because there is no row at position 17... I wonder why... but I'm not sure how to include a piece of code where it checks to see if the row or column exists. How do I check to see if the row/column exists? It's probably really simple, brain isn't working properly at the moment unfortunately.

I was wondering if there is a way to keep the same scroll position in a datagrid view as the app jumps around to various rows (driven by the user selecting different timestamps or address). After the jump happens, the horizontal slider moves all the way to the right, but I want it at the same position as before the jump (or at lease go all the way to the left).
I have tried numerous things (datatable.AcceptChanges(), etc) but haven't been able to figure it out yet.

I am now using a datagridview that uses just 1 col and 1 row, but is set such that it has a large display width to display a lot of graphics.
The horizontal scroll bar is active to help me view all the data, but the scroll bar defaults to the LHS.
How can I make it default to the RHS?Additionally, when I move the scroll bar, the displayed data seems to get corrupted - do I have to re-paint the graphics every time the scroll bar position is changed?

What I am trying to do is sort a datagridview and remove a row from its sorted position to the 1st row.
The problem I am experiencing is as follows:
in the source below, when the code runs "MeanRow" is populated with what is required. As soon as Rows.Remove() executes, the MeanRow datarow is lost. Why would this be if I'm declaring a new variable and simply setting it?
Code:
MeanRow = r
TabGrid(dgv.Name).Datatable.Rows.Remove(r)
Code:
Private Sub dgv_Sorted(ByVal sender As Object, ByVal e As EventArgs)
Dim MeanRow As DataRow

I'm writing an application for seat reservations. I use a DataGridView to represent seats. Each free seat is coloured in green and occupied seats are in blue.DataGridView is populated with names from database and user could add a name to a seat choosing from a list.Moreover the user has the possibility to move a name from one seat to another - not occupied via drag and drop operation.Eveything works well, but when moving a name from one cell to another I have to position the cursor over a cell that is one row above and four columns on the left of that one I choose.Which is the reason? Here is the code

On one of my forms i have a datagridview binded to an Access database. It displays only first and last names of my customers in a datagridview.What i want to do now is, when i double-click on one of the customers another form will open and display details for this customer (detailed view - textboxes).
What i have accomplished so far is that when i double-click on a customer in datagridview a form opens with details (linked to the same binding source as datagridview). But the problem is that it always opens the first record even if i dobule-click second or third in datagridview.I don't know how to bind these textboxes with current datagridview position?

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.

I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?

i've been creating a program in VB that connects to a Microsoft database, and up until now, the program has been displaying the information fine. however, all i get now is the error message "No row at position 0" whenever it tries to display almost anything.
I am baffled as i have 3 forms that work and are programmed exactly the same way and only 1 works fine :/

Lets say I have a label with the text "_ _ _ _ _ ", some underscores. Now what if I want the program to locate the 3rd underscore and replace with something else. Is this possible? I was guessing by getting the character's position first and somehow there is a function that replaces characters by their position.

In your opinion what API use Spy++ to get the "Rectangle" and "Restored Rect" data of a child control of an external window?I don't think it uses GetWindowPlacement because if I use this API for the main window I obtain the same values of Spy++, but if I use the GetWindowPlacement API to find the position of a control of the window itself, known it Hwnd, I obtain different results as to Spy++ (that are ALWAYS the same results also if I shift the Main window... so I think that are relative data and not absolute data... but they are wrong )
One example:
Spy++ : (620, 473)-(792, 505)
GetWindowPlacement: (615, 450)-(787, 482)
same dimensions... but different pos... and the right pos is the Spy++ pos.

I have a "Please Wait..." form that I show when doing some long task. This works quite well. But I cannot seem to control the opening position of the form. Currently I am using:
WaitWindow.StartPosition = FormStartPosition.CenterParent
WaitWindow.Show()
and this is just being ignored. The window opens at random locations. If I change it to CenterScreen, that works! But I don't want it center screen, I want it centered on the parent. Can I manually set the location? I am using VB 2008 Express and the wait form is a plain windows form.
