Horizontal Scrolling On A DataGridView?
Oct 20, 2010
I have a DataGridView with, say, a half dozen columns on it; the right-most column being the widest (a description that might exceed the window's width). If the user presses the Home/End or PgUp/PgDn keys to navigate thru the data, it will sometimes scroll horizontally to the right, which is annoying. Is there a way to prevent this?
I've tried .ScrollBars = ScrollBars.Vertical(so there's no horiz scrollbar), but that doesn't solve the problem. I'm not sure how to make the 1st column be always visible - but even if I make it visible upon displaying the grid.I guess basically I don't WANT it to scroll horizontally, except when the USER scrolls.

The use of shift + scroll wheel is fairly common for horizontal scrolling.
Both of those are fairly easy to capture. I can use the MouseWheel event with a flag set by the KeyDown, KeyUp events to keep track of when the shift key is pressed.
However, how do I actually trigger the horizontal scrolling? I am aware of WM_MOUSEHWHEEL, can that be used to trigger the event?
Update: For a System.Windows.Form there is a HorizontalScroll property that is of type HScrollProperties. You can manipulate the Value attribute on that object to change the horizontal scrollbar's position. However, so far I haven't spotted any other controls on which that object is available.

I'm designing a form with a horizontal scroll bar docked at the bottom. I wanted to add support for side-scrolling using mouse tilt buttons and found this solution which, after a bit of tinkering, seemed to do the trick - that is, while the form only had GDI graphics drawn on its surface.
However, since then I've added some controls to the form and found that when the mouse is over any of them the tilt operation only fires once-at-a-time instead of repeatedly as it does when the mouse is over any other part of the form.To see what I mean (if you have a mouse with tilt buttons) dock a horizontal scrollbar onto the bottom of a form, add a few other controls and paste in this code:
Public Class Form1
Const WM_MOUSEHWHEEL As Integer = &H20E
Protected Overrides Sub WndProc(ByRef m As Message)
[code]....
You'll see that side-scrolling repeats when the mouse is over a blank part of the form, but only "one-shots" when it's over a control.I'm guessing the solution lies somewhere in the message's .Result value, but I'm at a loss as to what that should be. In fact I'm not even sure I'm returning a correct value anyway because the code in the original solution threw an exception to the DirectCast function so I swapped that for CType, which seemed to work okay. I've tried working it out using Spy++ but I can't see anything obvious.
UPDATE:I've noticed when I include 'Child' windows in Spy++ there are two (0x020E) messages and two return values, 1 then 0. I presume the message is being passed onto the control by the form. So I guess the question now is: can the message be prevented from being passed to the control? Or can the control's return value be intercepted and converted to 1?

I'm having trouble finding a property of the DataGridView that allows me to turn on both Vertical and Horizontal Gridlines. Does this exist? I can't imagine it not existing but I can't seem to find it.

I'm using a DataGridView in VB.Net in VS 2005. The issue is, when there are rows that exceed the width of the DataGridView, the horizontal scroll bar doesn't appear (the ScrollBars property is set to "Both"), but an ellipsis appears at the end of each row that is too long. I don't want the ellipsis, but the horizontal scroll bar. The vertical scroll bar works as expected when the number of rows exceed the height of the DataGridView.
I have tried setting numerous related properties (changing the AutoSizing property of the DataGridView, Resizability of the Row Template, made sure that no Columns were Frozen) to no avail.

I am working DataGridView in vb.net08.The intresting task is ,When i move the Horizontal Scrollbar in DataGridView from Left to Right ,the First two Columns should be stable and moving starts from 3rd Column.Means If i moved at end of the right side but the first two columns should be visible. 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.

I have the following code to resize the datagridview but the vertical and horizontal scroll bar are not shown when there are colunns and rows exceed the width and height of datagridview objects.Bascially the following code is similar to dock to the botton, the only difference is docking to the botton change the Y position of datagridview and fill the botton section whereas my code fix the Y position of datagirdview and fill the bottom.[code]I have tried with the dg.ScrollBars = ScrollBars.Both but it it is not working as well..May i know how to get both scroll bars working.

A program I am making required that I write my own code for column reordering rather than using the built in column reordering in the datagridview control. When I am dragging a column my code checks if the cursor is near to the right hand side of the control and if so it scrolls to the right using firstDisplayedColumnIndex.
The problem I am encountering is caused by the fact that when I do my custom dragging of columns the display index is changed not the column index itself.So when my code tries to scroll to the right using firstDisplayedColumnIndex once it reaches the very right it jumps back and forth. This only happens when I have moved the first column and thus when the first displayed column doesn't have the lowest index.

I have a DataGridView where I bind a datasource (sql query) to it. The row count is high with many columns. Trying to scroll through this DGV is painfully slow.
Does anyone know of any kinds of optimization I can do so that I can scroll faster? Like what is the DataGrid doing when you scroll? Does it repaint every screenful? Does it validate every row? It seems like it is doing something unneeded when a user scrolls.

I generate a DataGridView using the result of a query. The query generates a LOT of columns (more than 75). Obviously the DataGridView does not show all of them. I wrote a small procedure that extracts data from the DataGridView and generates an Excel file ora .csv file.

Any way to "lock" columns in a data grid view so that when scrolling horizontally, the column will stay in view. Similar to the Freeze Panes functionality in Excel. I am using VB.net 2005 express.

I'm noticing that sometimes strings drawn in a given column or row will be slightly over-antialiased or altogether clipped after scrolling horizontally or vertically.I can see that the quick way to clear this up is to send a final .Refresh() call to the DataGridView after completing the scroll. But, unlike the ReSize event for Forms, there doesn't seem to be a Begin and End Scroll event for controls, so I can't just send a .Refresh() to the DataGridView after scrolling.Does anyone have an idea how I might go about detecting when a scroll event has completed so I can send that final .Refresh() to the DataGridView?

After scouring the articles online I have come up with this design for a winforms based touchscreen app that needs smartphone like scrolling. The app itself will run on a tablet laptop or touchscreen desktop.I put everything I want to scroll on a panel. Set autoscroll to true (which will show scrollbars)Now put this whole panel inside a groupbox.Shrink the groupbox until the scrollbars are hidden (visually hidden, not visible = false)
Now the fun part I am stuck at.I think I have to handle the mousedown, mouseup & mousemove on the panel to set the autoscrollposition so that when someone touches the panel and drags, it does it's scroll magic. Please help fill in the few lines of code in below method stubs. The msdn doc on autoscrollposition is very confusing since it returns negative numbers but needs to be set to positive with abs and what not.

Point mouseUpPoint;
Point mouseDragPoint;[code]......

I need to limit a Textbox and DataGridView to only enter text in the fixed size of the cell/textbox on the screen. So I have limited the cell/textbox so user can not change it size. Both allow multiline and wordwrap. cell/textbox is sized to accept 5 lines of data (wordwrap or enters) This is like an online form.So the text enter will be printed so I can not allow scrolling in the cell/textbox.
How can I stop the scrolling of the text inside the cell/textbox.
Also : if the user Paste into the cell/textbox how to truncate text if larger than display area.
sample settings:
DataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.None
DataGridView1.AllowUserToResizeRows = False

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'm using VB in Visual Studio 2010
When I resize my form at run time (border set to sizeable) .Net automatically adds scroll bars.
I can pick the vertical scroll bar ok but on the horizontal scroll bar it always shows the resize cursor and so I cannot pick it.
Is there some way of controlling the zone within which the resize cursor is active or the active width of the border detection?
