I have a big datagrid view, with datasource set to datatable with 15 columns, and about 350 rows.
When I change the size of the window with the datagridview it isn`t resizing smoothly.
How could I make the resizing more smoothly?
I want it so when you click a button you have to select the window you want (A Temporary Red box appears round the window your currently selecting). Then when you click the final window decision then it will put a new form on then resize the form to the selected window!! how??

View 2 RepliesI am developing an application for the first time and need guidance.Developement Env: Visual Studio 2005 Pro, Visual Basic 2005 , Windows XPApplication Target: Windows XP & VistaI developed the application under a screen resolution of: 1680 x 1050 pixels. When the application is installed on any computer with lower resolution, my application window does not size properly and many of controls end up "messing up". How can I fix this issue?Also, I have noticed when I resize my application by dragging the bottom right-hand corner the application does not really re-size, it just gets covered.

View 1 Replies[code]i want to extend the window width everytime i expand the expander control to the right.when i run the above quoted xaml and expand the expander control after the build, everything works like expected, but as soon as i manually resize the window, the content of the expander control will expand into the existing area to the left. how can i change this behaviour, so that the window will extend its width to the right side and the content will end up in that new area?
View 1 RepliesI'm looking for help resizing a label's size and its font size based on its window size.That's to say when a window resizes, the label itself adjusts it font and background box to do the same.I know I'm triggering something on the Resize event of the form, but I don't know what.
View 2 RepliesI have drawn out a datagridview onto my form at a certain size.But, say I have 3 rows of data and they dont fill the grid to its bottom. So I'm left with a bunch of empty grey color stuff in the rest of the control below.Is there any simple property/method that will fit the control size to just the rows loaded, or am I being too picky?
View 2 RepliesI've set every setting I could find on the DataGridView to a specific font size however when the form it resides on loads I step through the code and put my cursor over the DataGridView1.Font.Size and it always shows 8.25 (I've set everything to 18).
What I'm trying to do is resize the DGV on load of the form to a percentage based on the size of the form relative to the size of the screen. Everything else on all of my other forms are resizing correctly but the DGV is not.
Here is the designer generated code for property reference:

I have implemented couple of websites) drag and drop functionality between two Datagridviews (i.e to be able to add/remove columns on the fly). After much playing, I have managed to make this work, however it now presents a new issue - I cannot resize the columns.Below is the code for this, but I can't see how I would need to change to accomodate the resize (the drag and drop effects dont have it as an option, so I assume I need to stop the dodragdrop when the resize is taking place, but I'm not sure how to do this.

View 15 RepliesCurrently, my application is comprised of:a Main Form On this Form, lies an array of User controls, (pardon my terminology, i believe the more proper VB.Net term is Collection of controls). Within these controls are pictureboxes that have distinct graphics drawn on them. When I run this program, no graphics are drawn in the pictureboxes or it appears the graphics are overwritten. Also, it seems that the Form resizes uncontrollably varying in size on the screen and hits an infinite loop. I use the Form_Resize function for updating the size of the form. What could be causing this problem. What is the Paint method used for?Currently, to draw graphics on the Pictureboxes i am using the graphics object. I have two pictureboxes within the usercontrol for toggling back and forth for a more fluid refresh upon property updates.
From my reading, vb.net does not allow the ability to create an array of controls on a form, so I attempted to create an array of controls dynamically to try and stay as close to my vb6 application as possible because my knowledge is limited. This works, from what i can tell I know that in the Upgrade wizard the VB6.Compatiblity reference was used to try and mimic an array of controls, but I wanted to steer away from that and program strictly using VB.Net commands.

I have a form that sits on the user's desktop. It's only purpose is to display specific information about the computer. The layout is basically setup like this:
[Code]...
I want to be able to give the user the option to display whatever data they choose. In doing so, I'd like the form to resize itself based on the how many labels are in the form and for the labels to align vertically.
Can anyone point me in the right direction? For the form, I was thinking I could get the location of the last label and offset it's size by the location, or something similar.
developed my app on a Vista laptop and deployed it on an XP desktop. When deployed the Form and even some controls are resized so text and portions of controls are not visible.Next I moved the project files and VB to the XP desktop and published the application on that machine. Same result, in fact the sizes were changed within the properties of the forms and controls within the project files

I'm trying to set up a system to resize multiple objects on a form (40+) when the form resizes. I've got it working but it's rather slow, when I resize the form it stutters a lot from looping through the objects to resize them. Is there a better way to do this that would not cause the stuttering effect?

I am using a Thread object to perform a function. This function performs a task and displays its progress in the gridview (like adding rows changing text etc )
The reason I am using a thread for this function is that there is a cancel button on the form. While the task is in progress, user can click on cancel to abort it.
Private Sub BtnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnStart.Click m_Thread = New System.Threading.Thread(AddressOf myfunction) m_Thread.Start() End Sub
The function works fine and thread is completed. But calling any method of datagridview after thread is completed ( outside the worker thread ) generates an error- "Error creating window handle".
That's probably because i am not using the invoke method of datagridview for calling its methods or readingwriting properties Do i have to create separate delegates for all the methods properties used in the function ( worker thread)

View 7 RepliesI am trying to add a checkbox column to a DataGridView in a simple window forms application.
I am pulling back some data from a database using ADO.NET, putting into a datatable, and then setting the datagridview datasource to the datatable. I then want to add a checkbox column as the second column. So far I have this code that seems to work:
' Code here to connect to database
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable
[Code].....
This code 'works' and I get MyDataGridView to show the data with the checkbox column in the correct position in the table.
However, for some reason, I cannot check any of the check boxes in the DataGridView? I have tried lots of things (e.g.altering the readonly state of the column) but cannot get it to work.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 2 RepliesI want to know if VB.Net already has a control like this before I start wasting time building my own. I have a DataGridView that shows the row error symbol in the RowHeader if the update to the database is unsuccessful for that row. Currently, if you hover the mouse over the error icon it will show a default tool tip to display the error text.I would like the user to left-click the RowHeader and a small popup window will show the error text. Then when the user clicks somewhere other than the popup window it will disappear just like a context menu. do I need to build a form with no borders that has a large textbox in it, then setup an event so when the form loses focus it closes? Or does a context menu strip have the ability to support a large textbox? Or do I use a splash screen?

Currently I am re-loading the datagrid on the initial form with all the data once I close the second window down.
