I'm trying to make an autoscroll enabled panel that will scroll if the mouseposition.x > panel.location.y However, I cannot seem to find a panel.scroll() function. Is there a way to programable make the control scroll?
View 1 RepliesThis is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.
How do I get the possition of the mouse inside a panel? I know how to get the positon in a windows form but this doesn't work in objects (pictureboxes , labels, panels...)
View 1 RepliesBasically I want to move my mouse to the coords that is received based on the location of a certain coloured pixel. I can get the coords of the pixel but when using them on mouse position, the mouse position is based on the entire screen rather than the form. How could I change the position coords based on the form rather than the entire screen. E.G. If a certain coloured pixel is 2,2 in a form and I put that as the mouse position, it would go outside the form but I dont want that. I want it to hover of the pixel coords
This is my
Dim bmp As Bitmap = DirectCast(PictureBox1.Image, Bitmap)
For x As Integer = 0 To bmp.Width - 1
For y As Integer = 0 To bmp.Height - 1
If bmp.GetPixel(x, y) = (Color.FromArgb(108, 90, 60)) Then
Windows.Forms.Cursor.Position =
End If
Next

How would I leave the vertical scroll position as it is and set the horizontal scroll position all the way left if it isn't already in that position? I've been using Me.AutoScrollPosition and have come up with code that is satisfactory but I haven't been able to always leave the vertical scroll position exactly as it is and just move the horizontal scroll position to the left limit.
View 4 RepliesI am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.
View 4 RepliesI have a tab control with two tab pages. One page has the auto scroll enabled since there is to much content in the page. The middle mouse wheel doesn't scroll the scroll bar; I have to actually click and hold the scroll bar and drag it down to scroll. Is there a property to allow this?
View 2 Repliesi have 2 controls on a form. Panel1 and picturebox. I am using the following code to zoom in.

'PicBox1st.Top = PicBox.Top - 20

I have set the panel to autoscroll and added scroll bars but they do not scroll far enough... They only scroll about 2cm.
Following default the datagridview will scroll following vertical. How can i do that. I tried :
DataGridView1.ScrollBars = ScrollBars.Horizontal but not work
Apologies as this has probably been answered a million different times a million different ways already. I'm trying to control the mouse. I wish to move the mouse to a given pixel position (x, y) and cause a click. I don't want this to be limited within a form, as I want to control another application. I'm using VB 2005.
View 4 RepliesI have a problem with a certain panel in another panel.
I have declared a panel on my mainform that is called panel1 ( dock: fill)
In this panel is another panel ( panelmain )with size 10.000, 10.000 pixels. Now I put the auto scroll property of panel1 to true, so then the panel1 has scrollbars on both sides and can show the whole panelmain.
Now the user has the ability to zoom, which basically means that I just scale Panelmain with all it's child controls.
Like Panelmain.Scale(0.95) ( To zoom out )
And panelmain.scale( 1.05) ( To zoom in)
This works well, but when the user is using the scrollbars in panel1 and after that zooms in ( or out ) the location of panelmain is changing. So I tried to solve this by docking panelmain inside panel1 at the left. But now the vertical scrollbar is gone. how I should dock panalemain inside panel1 to prevent panelmain from moving around but also in a way that both the horizontal as the vertical scrollbar are present?

View 11 RepliesI have an ASP.NET form with multiple steps (using the Wizard control). When advancing to the next step, I want the page to start at the top, but for some reason it is maintaining the scroll position. I set the Page.MaintainScrollPositionOnPostback property to false, and I have the next button event handler set it to false also. I don't have the property set to true anywhere. But it is still maintaining the scroll position. What could be the issue here?
View 1 RepliesI 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'm looking for a simple, efficient way to get the position of the browser vertical scrollbar and save it into a session variable in an ASP page. What I'm trying to do is when the user changes a page I've the scroll position stored in a session variable so that when the user returns to the page the page will scroll to their last position.Is there a way to do this? I've seen examples of persisting the scroll position on postback but nothing yet doing exactly what I'm trying to do [code]
View 1 RepliesWe have a page which will diplay around 150 records at a time and for each record there is a link to input data. I want to be able to click that link on any record and have this one div with all the fields and updatepanel popup next to it.
I have found many JQuery examples of this, however none of the JQuery examples will allow me to Async-postback from the div which is very annoying. I also found examples where I place a div below each link and it pops up nicely, however this wont work because I need this to be only one div which contains the updatepanel and the associated inputs.
Do you know of a simple way to popup a div relative to the link? preferrably to the lower left of the onclick link/object.
I cant use the CSS left/top/right/bottom stuff becasue I need this to be relative to the object and not the entire page.
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?
What I am doing is I have an image in the webbrowser control that I am trying to capture and save to my computer but the image url is created dynamically and destroyed on the loading of the page (which keeps me from being able to use httpwebrequest to retrieve the image that corresponds to the page I am currently on). To get around this I am resizing my webbrowser control to the size of the image and taking a snapshot of the browser window itself.
The problem isn't with taking the snapshot... it's that when I take the snapshot it is snapping an image of the browser window prior to scrolling. I would like to figure out the scroll coordinates so I can basically write a function that will "pause" the routine and wait until the scrolling coordinates match that of where the image is located and then proceed to take the snapshot.
I have tried the .ScrollTop / .ScrollLeft values and .ScrollRectangle.Location.X/Y but I keep getting 0 as a return. Does anyone have any information on this? I've searched all over google but only find people asking the same question as me but recieving no answer.

View 5 RepliesI have a windows form which contains a group of panels in a flowlayout control. Each panel has a button acrossthe top which is always visible and clicking on it expands the panel to view the other controls on it. clicking on it again shrinks the panel back to the size of the button. A simple form of menu. The flowlayout control has autoscroll enabled and as enough panels are resized (opened) they obviously are too big for the form and a scroll bar pops up.To get the most recently opened panel in the viewable area I use
FlowLayout.ScrollControlIntoView(pnECBF)
where pnECBF is the panel just resized. This works but places the panel at the bottom of the form i.e just in the visible area. I want the user to be able to see the panel AND the next menu button which is on the subsequent panel. So basically what I want is the panel into the visible area +25 pixels for the next panels menu button.
I have a RichTextBox and I need to find the position of the vertical scroll bar.

View 2 RepliesI have an issue with maintaining scroll position.I am almost positive that I have everything set correctly. I have updated my web config...
<pages maintainScrollPositionOnPostBack="true"
and everything seems to work fine UNTIL....When ever my Gridview returns a lot of pages, like more than 50, sometimes upwards of 100 or more, I show 50 records per page. The farther into the Gridview, the more the scroll position is off.So what I am saying is that for the first 20 plus pages or so, if I scroll down the page to the point where the top rows have moved off the screen and I enter Edit Mode, the correct record remains in view on Postback.But if I am over say around 30 pages into the Gridview, the further in the worse it gets, when i enter Edit Mode I have to scroll back down to the location of the record that I selected to edit.
