MDI Child Froms Focus And Scrolling?
Feb 4, 2011I have achieved for the most part what the users want, which is to be able to have multiple MDIChild forms open at once for example the Child form displaying the data and the Child form displaying the user's manual. The child forms can be resized to some extent and can be moved around within the Parent form. When the user clicks on the title bar of one of the Child forms or selects a menu item opening a new Child form the newly opened Child form or the Child form on which the user has clicked the title bar gets focus.
I also have one Child form which will not scroll with the mouse wheel even when it has focus. Actually there is very little of the form that is not ocvered with controls. It has about 8 group boxes with several otehr controls within the group boxes. When I click on a list box within one of the group boxes the list box will scroll through the values, but when some other control gets the focus or the forms itself has focus (via clicking on the form's title bar)the form will not scroll with the mouse wheel. The other Child forms do scroll with the mouse wheel.The AutoScroll and AutoSize properties of the Child form are both set to true. I also have VerticalScroll and HorizontalScroll visible and enabled properties sey to true
How To Stop Auto Scrolling When Control In Panel Gain Focus
Dec 14, 2010I have set a scrollable control's autoscroll to true. What do you do when you don't want a scroll to occur? For example, suppose you have a RichTextBox and a button side by side as below:
Notice that "button1" has the focus. If you click on the RichTextBox to give it focus, the scroll bars will scroll until the upper left corner of the RichTextBox is in view.
But what if, for whatever reason, you wanted to keep button1 in view? How would you do that?

Horizontal Scrolling On A DataGridView?
Oct 20, 2010I 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.

View 4 RepliesVS 2008 DataGridView Column Scrolling?
Apr 22, 2009A 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.
[2005] DataGridView Scrolling Optimization
Jan 26, 2009I 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.

View 2 RepliesVS 2010 Sending A Final .Refresh After Scrolling A DataGridView
Apr 29, 2010I'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 RepliesC# - Get Smartphone Like Scrolling For A Winforms Touchscreen App ( Scrolling Panel )?
Aug 5, 2011After 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.

VS 2008 Stop Textbox And Datagridview Cell From Scrolling (fixed Size)
Aug 16, 2011I 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
