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 have a panel on my winform that is one third of the form size. I need to insert 4 datagidviews side by side into the panel. The user should be able to scroll horizontally to view each DGV. I can position the DGVs side by side within the panel but it does not scroll the whole horiz way to see all the DGVS.

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.

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?
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

Essentially, what I'm trying to do is build a table of data dynamically on a page that is 3 columns wide by however many long.Working off a Classic ASP example, I've gotten as far as trying that, but not all the records display and they still render on the page as rows instead of columns.[code]I'm not overly certain how to do it, and I'm fairly sure it's probably really simple to do on a view page.My other option is to set a finite amount of records to be created and build the table on the page from that, but I'd much rather do it dynamically.I guess also an alternative option would be to use a repeater control? Though I don't know if this is a control that will work with MVC.

View 1 Replies1. How to make content in a label scroll horizontally from the right to the left? And I want it to loop nonstop so that it can keep scrolling once and once again nonstop.
2. For example, my label is multi-lined and has line A and B. What about if I want:
Line A scroll from the bottom to the top -> Line A pauses for 10 seconds(for users to read it)-> after that line A dissapears itself -> line B scrolls up -> Line B pauses for 10 seconds(for users to read it)-> after that line B dissapears itself-> (back to the first step)
*Same, I want it to loop for unlimited times.
I'm building a simple WFA with a label that changes and gives instructions to the user as they work their way through the program. Is there a way to programmatically re-center the label horizontally after each text change so that the label is always centered in the form regardless of what text is present?
View 1 Repliesis there an easy way to make the size of a datagridview expand dynamically (like say it is not long enough to display all the data it will grow in width), or do i have to implement this functionality manually?
