I 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?
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.
I 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]
We 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.
I 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'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?
I 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.
in my program were ever you click on a picturebox it draws a image, that works, but the picturebox it in a panel so that when the picturebox gets to big scroll bars appear, that works, but when i scroll down the picturebox and click it wont put a image exacly were i clicke, but if i did not scroll at all and click it works just fine.
I am currently working on a VB.Net program where there are two parallel multiline text boxes like this.
----- ----- | | | | | | | | ----- -----
I would like that when one text box is scrolled, the other is scrolled as well. I was wondering if there was a Scroll event that could trigger the change the position of the scroll bar of the two text boxes.
Without using TopIndex, EnsureVisible, etc., is there a way to simply save the current scroll position of a listivew as a point, then reset the scroll position to that point after reolading the listview?
I am using the Tabcontrol with autoscroll = True feature, when i make hidden controls visible on the tab there position is out of place, one work around for this is to set the scroll position to 0,0 by doing this...
I am running Microsoft Visual Studio 2008 Professional on a Windows 7 system. While working on the visual basic exercise in chapter 4 of the Microsoft Visual Basic 2008 Step by Step book on the MyMenu program I added a Toolstrip to my form and then I was trying to perform the add OpenFileDialog and ColorDialog controls to the component tray as described at the bottom of page 111 under Using Dialog Box Controls. I could never get the controls to appear in the component tray as instructed in the book.
I have a program that plays a video and uses the step function to move frame by frame backwards and forwards through the video. The forward frame works just fine:
AxWindowsMediaPlayer1.Ctlcontrols.step(1)
However, the backwards step (below) jumps a full second backwards while the forwards step only steps .033 seconds forward (presumably a single frame).
AxWindowsMediaPlayer1.Ctlcontrols.step(-1)
I can't find any documentation about this problem online and in fact I can't find much mention of this function.the documentation does say the -1 command should step back one frame. IWMPControls2::step method Is this a known bug or is there an updated function I should be using?
I really need to learn much about it, but always stock up,.DOTNET covers the vb.net, C#, C++, ASP.NET, .NET framework is it right?.C++? ASP.NET?What should be my step by step procedure?
Will I start on database? Connection of client and server? Webrowser? Application?...etc etc etc.Will it ok if i start on studying every toolbox item one by one?
I dont have any project or every assignment that needs to be done....All i want is to learn about DOTNET
coming to the topic i want to learn dotnet i am not good at programming. but i want learn it i m very passionate about it.you all know soo much about DOTNET even i want to become like you people.i have a bit knowledge about this but not much..What should be my first step towards this?How should i start with and from where should i start with?
My need is to work with what I have (2005 studio), what I know (Visual Basic) but need a primer. I am a visual learner (so I need to see [1] how the form is created, named and set up). From there I need to see [2] how he code works so that I can implement from there.
I have a wizard where users need to fill out data. You cannot navigate to the second step until first step is completed.
I enforced this behavior by disabling/enabling "Next" button, but I really do not like this solution, since it seems not really elegant or safe here. What is the good approach on building step-by-step processes with enforcing step completion.
I'm trying to understand how this code work step by step but I'm confusing How the code work when executed from first step to last step?example: when I set obj to age = 39 . is the first step is checked if the variable in m_Age or checked in Property Age
vb Dim obj As New Minimal obj.Age = 39 MsgBox("after setting the age to 39, age is " & obj.Age.ToString) vb Public Class MinimalPrivate m_Age As Integer Property Age() As Integer Get Age = m_Age End Get
I seem to lost the practice files disk for this book, and I am trying to 're-learn' this book. I am unable to do the lessons without the practice files. If you have the disk and could maybe zip them up and email them to me? I have the other disks still, and am using the Visual Studio Express to do this.
Is this the correct forum for questions regarding code in the Visual Basic 2008 Step By Step? If so I would like to know why there is a declaration for one PictureBox and not the other. If there is a better forum for Michael Halvorson's book, can anyone direct me there?
i would like to ask for little help in here. I developing application for wake on lan and i have group of checkboxes button and i sub with threads. My problem is in button event i would like to run sub only if checkboxes are checked. All works but problem is when i have this rutines in button action then it start threading all the same time. Its very hard to explain. Bassicaly i wanna read this if checkboxes systematicly 1 by 1 from top to down coz right now in my multitexbox(status) they are all mixed and i can't recognize what belong to what.
When I started to work on this new project in vb.net 2010, I put many breakpoints to try to understand the execution order of the project, only to find it in vain. Step into command F11 should work correctly according to Visual Studio 2010: Step Into Property/Function(F11) doesn't work as expected. But I when I pressed F11, I found the code is jumping from one place to another based on breakpoints, not line by line or step by step.To give an example, please see the code below
When I press F11 at line 1, it goes to the property 1. After it returns, when I press F11,it goes to property 3 directly, without accessing the code in line 2 and line 3.I do not understand why the code is NOT executed step by step by using F11. If I put breakpoingts in line 2, then line 2 is executed.So it seems to me that the showed execution order is based on breakpoints! So if I put breakpoints at different places, the showed execution order would be different! Thus, it is impossible for me to really understand the execution order.
