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.
I have some data in my DataGridView. I want the user to be able to scroll through data but not select any item. If I make enabled=false, even scrolling does not work

View 1 RepliesI have a datgridview that has two columns that allow text wrapping.When I scroll past the visible portion of the grid I can only see a single line of text even with a refresh call on the scroll event.
View 4 RepliesA 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.
View 2 RepliesI'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?
View 5 RepliesAfter 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.

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 form which has a horizontal scoll bar, a vertical scroll bar, and a panel. The 2 scroll bars move the panel. When I execute the form, the panel will scroll under the horizontal scroll bar when using the vertical scroll bar. But it scrolls over top of the vertical scroll bar when using the horizontal bar. I don't understand why 1 of them goes over and the other 1 goes under. Is there some property that controls this? Or some way to that 1 set it up wrong? The vertical scroll bar is on the left edge of the form , to the left of the panel, and the horizontal scroll bar is near the top of the form, above the pane. Can anyone direct me as to how to get it to stop scroll over this bar?

A long time ago I wrote a program in VB6 that performs sideways scrolling by:creating a couple of device-independent bitmaps twice as wide as my display window.plotting my streaming data on the first bitmap until it reached the right edge of the window.copying the bitmap to the display window at the refresh rate.copying the data to both bitmaps, the second bitmap starting at x = 0 when the first reached x = windowWidth
ping-ponging the two bitmaps as the data continued to arrive The result is a display that scrolls sideways continuously as long as the data stream is flowing VB.NET and Windows.Drawing hardly support any of the VB6 tools I used to do this, and I can't find anything in the documentation that can take their place.

View 2 RepliesI have a textbox to which text is continuously appended (every second new status data at the end).I would like to act it as follows:- When the cursor is positioned at the end: Stay at the end, scroll the textbox (text disappearing at the top).- When the cursor is positioned somewhere else (not at the end): Stay exactly there, don't move the cursor, don't scroll, don't change the top line of the textbox.This seems to be surprisingly difficult (tried quite several ways).This is how far i came:
Private Sub addToTextBox(ByVal daStrg As String)
Dim posAtEnd As Boolean, selPos As Long, selLng As Long
If myTextBoxForm.txBox.SelectionStart = myTextBoxForm.txBox.TextLength Then

I have a read only multiline text box I'm using as an output box for a continuous string of data, when my data gets to the end of the last visible line the scroll bar activates and my text vanishes past the bottom edge of the text box and I have to manually scroll the text box to get back to the end of my data. is there anything I can do to make the text box scroll up so I always see the end of the data stream being past to it?
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox2.Text = TextBox2.Text & TextBox1.Text
End Sub
End Class
Above is a really quick and dirty bit, take input from one textbox and output to the other using a button click or some such. After so many button clicks get the text box to scroll without doing it manually with a scroll bar, so you always see the latest entry.

I've already disabled scrollbars, but I want to go further than that.
I'm looking for an example in VB.NET of a continuously scrolling form. This would be similar to a continuous form in Access but with a major difference in that when you scroll it the whole thing moves up or down instead of the data jumping up or down to the next section. If you are not familiar with Acces, this would be a form that lists data down the form in sections, one per record, in other words, like a bunch of forms strung one after the other. When you scroll down, the record at the top gradually disappears and is replaced with a new one at the bottom.
This needs to be a form with controls, not a datagridview.Right now, I'm trying to find an example of this. I tried searching for one and couldn't find one. Does anyone know of an example of a continuoulsy scrolling multi-record form where the whole form moves in VB.NET?
