I have a DataGridView in one of my form which at a certain point I resize an change it's position. I would like to be able to restore it to the designer's default position at runtime. I know I could save it before changing and then restoring it later, but I feel like there surely is a way in .NET to just restore a control position to it's default.
View 2 RepliesI know that you can use this code for the position.x of the mouse:
System.Windows.Forms.Cursor.Position.X
but how will i detect the position.x of the mouse inside the form? i mean counting 0,0 from the edge of the form not the screen...
after i run the program, the form pop up showing no problem.however, when i click on the maximize button on the top right of the form, the form enlarge and fill the screen. but the components will not move accordingly.
View 2 RepliesI set the form's size with Me.Size = New System.Drawing.Size(500, 500). I display the mouse cursor's position when the event Form1_MouseMove fires. At the bottom right corner of the form, I read the coordinates 483,460 (instead of 500,500) I precise that the upper left corner has the coordinates 0,0.I also notice that the size of a control differs from the form's size. for example if Picbox1.height = Form1.height, then the Picbox will be bigger than the displayed Form1.
View 4 RepliesI am designing a simple user interface using winforms. In the designer I have a panel on the form and would like to add a datagridview control into the panel at runtime and set the dock property of the datagridview to 'Fill' so that it fills the panel.
I am struggling to do this and following code is not working out for me:
Dim MyDataGridview as New DataGridView()
MyDataGridView.Dock = DockStyle.Fill
Me.MyPanel.Controls.Add(MyDataGridview)
I don't get an error but the datagridview isn't visible. It gets added 'behind' the panel and so I tried using .SendToBack() and .BringToFront() methods thinking that the panel was hiding the datagridview but this doesn't seem to work either. At any rate, it seems like the datagridview is being added to the form but just not docked within the panel
I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?
I had a master form which has a MDI container.When I was load the master form, I will also display another form inside the MDI container.But I was fail to maximize the child form to fix the MDI container. The image below is my problem Untitled2.jpg. I need to expand the form above to touch the MDI container border. (Full size in the MDi container)But I was fail even I was set the child form window state to Maximized

View 4 RepliesI have created an ASP.NET class derived from the standard WebControls.TextBox, with the intention of adding extra properties that will persist between post-backs. However, I cannot figure how to get the values in these properties to persist. I have tried setting the value of the properties into the controls ViewState as part of the PreRender handler, but the value is then not accessible in the Init handler on the post-back, because the ViewState has not yet been setup.
I could look for the ViewState value in the Load handler of the control, but if the page/usercontrol that is using the control asks for the properties value during its Load handler, the control hasn't yet reached it's Load handler, and it therefore not there.
[Code]...
In the end, the way I managed to get it to work was to use a <asp:PlaceHolder> control within the repeater, create an instance of my control within the ItemDataBound handler of the repeater, and then add the control to the <asp:PlaceHolder>... all done within the Init section (which fortunately I'm able to do).
As Andrew found out in this previous question you can end up in a chicken/egg situation, where you need to create the controls in the Init, but you won't know what controls you need until the Load.
I have an MDI application that uses the menustrip control. When the MDI Child window is maximized, there is no way to restore its size. There's a restore on the MDI parent but that restores the entire application. However, when I use the Main menu, there are two sets of Maximize/Minimize controls, one for the MDI parent and one for the MDI Child. The Mainmenu control adds a band that is used to display the Maximize/Minimize controls but the band the menustrip creates is not used to do the same.

View 3 RepliesI have a form that I want to have a control box so you can close it at any time but I don't want it to be movable from its origainal position. It opens maximized and I want it to stay maximized. I've tried all the different FromBorderStyle options in properties and I've tried all the SizeGripStyle properties though I can't say I've tried all the combinations possible between those two but whatever I've tried I can always click on the border at the top and then the form breaks free from its starting position and when it does the vertical scroll bar disappears.
How can I have this form stay in place with the vertical scroll bar and the control box and not break free from its starting position if someone clicks on the border at the top? If I try FromBorderStyle None then I don't have control box to close it. I was looking at the form events list and I noticed when I break the form free by clicking on the border that that is a ClientSizeChanged event.
I'm using the VS 2010-Net 4.I have develop an usercontrol that is compiled on one DLL and when I reference this DLL in other applications the usercontrol doesn't look like it was desined. It looks all wrong.
In the same project of the usercontrol if I put the control inside of a form there looks the way it supose to but in other projects as reference doesn't.
I am writting a program that aims at filling up bookmarks of a template with data retrieved from a sql server db.

I have a user control in vb.net application.and i have a form in vb 6.
so in my vb.net applciation to this user control i need to mention the vb 6 form as its parent.
Means when i run a vb6 application i should see this user control as a part of that form.
I have a customer which as a Visual Basic Project in single instance mode with a wired presentation logic.
The main form contains a TabControl with mutliple TabPages.If I click on TabPageA another form is shown in front of the Form and resized to have the same size as the TabPage.
If I click on TabPageB the first form is hidden and another form is displayed.So basically for the user it looks like you have a TabControl with different TabPages which is not the case.
I tried converting the Forms to UserControls and put them inside the TabPage, but, thanks to the SingleInstance app, this would take a whole lot of refactoring. I tried it but eventually gave up because of many many runtime errors and I don't want to put any more effort in this.

I am developing a software using microsoft visual studio basic 2010. I used a datagridview control to display a list of data from product table. What I want to do (actually I am not sure how to do it, or is there a way to do it), when I choose one of the value in one of the column inside the table, I want it to open a form that contain data(details) based on that value.
How to do it? How to call the value that I pressed, so it can be used to open a new form containing the details of that value
Example of the data: (the "system" column) SYSTEM
topaz
nex1300
Nec
If I pressed "topaz" system, it will prompt me to a new form containing the details of that "topaz" system.
I am writing a Windows form application where a client has the ability to add as many chart as needed in the form by clicking at an icon in the menu bar at run time. These charts will have the same format, and I will have them linked to a text box for the client to select which entity to chart.I have no clue where to start. I did a web search and I have found articles that show how to add user's control at design time (I don't think it is what I want).

I create a control with a single label in, I don't change anything except the colour of the control and the label and also making the label anchor to the edges ( with a small border around the edge)

as you can see in the second image the control has lost its white border at the right and bottom.

I tried this for my forms, but because I am setting the position with a re-size function and anchors as well, it does not seem to work quite right.
I end up with grey lines (edge of a control I think), and some of my text boxes loose their position. What do you recommend? [URL]
