Get DatagridView To Scroll To A Certain Line
Sep 10, 2009
I have been using this line: Me.dgvWpt.FirstDisplayedScrollingRowIndex = to alter which line is first displayed on a DGV that is located on a tab. I have been trying to get it to scroll to a certain line, which changes, but that's irrelevant, when the grid is first viewed. I have been unable to get this to happen. After the first time it is viewed, I can use that line to scroll the DGV to any row. The code I use to automatically scroll it to various places works perfectly anytime after the first time it is viewed, but it is ALWAYS showing from the first row the first time it is viewed.

I have a DataGridView with a panel above it, that contains a group of textboxes above each column. My DataGridView has a horizontal scroll bar. What I want to do is when the DataGridView scrolls horizontally, scroll the panel with textboxes above it, so they stay aligned.I tried handling the DataGridView's scroll event, but I'm not sure what to do with it.

I have a DataGridView as my main application use. This grid refreshes very often, it is used to sign our staff in and out of the building and it updates their status.The problem I'm running into now is that if there are more items in the datagridview than can fit on the screen I'll get a vertical scroll bar. Which is perfectly fine in and of itself, but with the grid refreshing as often as it does it will always put the user back to the top. If someone were to be at the very bottom of the grid when the refresh

I have a datagridview located in a tab of a tab control on a windows form. The data is populating to the grid with out any issues. My problem is that the sizing I'm making 2 of the column of data moves the last one partially off out side the normal size for the grid. I have Scrollbars set to both for the grid. But I do not get the Horizontal scroll bar. If I hover the mouse over the partially hidden cell I do see the full text in a tool tip.
Am I missing some thing on setting the scroll bars here.

How can I programatically control the position of the vertical scroll of a DataGridView? I need to keep visible the last row added to a table and showing as the last row at the bottom in the DataGridView control so the user doesn't have to be scrolling down every time to see a new row that has been added.
I can see the use of the Offset for the Horizontal Scroll Bar but for the Vertical Scroll bar of the DataGridView it can only be "Get" but not "Set".

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?

I have a datagrid control in my winform application. It has nearly 30 columns. First 2 column are frozen and others can be views using scrollbars.
Its working fine.
I would like to add some functionality on it by allowing user to select a column from column list above and making the datagrid scroll to that column automatically.
So i would like to ask how could i make my datagrid to scroll to specified column automatically.

I have a datagridview which I am populating of a database, scrollbars are disabled to allow for autoresize
I created a Scroll Event that causes me some issues:
1. I can scroll down only
2. To move from one row to the next I need to rotate the mouse-wheel up in between two rows - as if the row index isn't being updated
3. The procedure results in an error : Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Public Sub grdScroll(ByVal sender As Object, ByVal e As ScrollEventArgs)
Dim RowIndex As Integer = grdAccountTypes.CurrentRow.Index + e.NewValue
' grdAccountTypes.CurrentRow.Index = grdAccountTypes.CurrentRow.Index + e.NewValue
grdAccountTypes(0, RowIndex).Selected = True
