I have an application that uses DataGridView in two different locations. In one location, the DataGridView shows everything fine. In the other location, whenever the form containing the DataGridView is initially loaded, only about half of the visible portion of the DataGridView is actually drawn; through the rest of the DataGridView, the underlying windows graphics can be seen; if you scroll down through the rest of the data, you get a choppy view of what corresponds to the bottom row being scrolled upward through each scrolled row. The only ways to get the DataGridView to show the correct values are either to select a cell, forcing that particular cell to redraw; or to invalidate an area of the window, causing that area to redraw (which it does do correctly).
I've compared how each of these DataGridViews were set up: For the one that works fine, the DataGridView is statically bound to a BindingSource, which is statically bound to a DataSet; the one that has the draw problem is statically bound to a Binding Source that is dynamically bound to a DataTable during the creation of the form.
What could be causing my DataGridView to not display correctly?
I need to get the DataGridView to perform the way it should perform. I'm new to the .NET environment, but I learn fairly quickly. However, I find it difficult to decipher themassive black box of the DataGridView control enough to make it do anything other than what it already does--Draw very slowly.
I have a Datagridview collections embedded in several Tabpages of a TabControl. I want to use to control Button to import data to the datagridview. Data is different for different datagridview. I want to know which DataGridView is currently shown (on the top) when I click the control button so that I can send corresponding data to it. What shall I do?
I am trying to create a datatable to be shown in a datagridview.. i have created a DataGridViewComboBoxColumn that has a data source and now i wanted to create a DataGridViewTextBoxColumn but i dont know how to make it take its data from a column in a table.. i did it with the comboboxcolumn but i coudnt do it with the textboxcolumn..
I have a MainForm which contain SecondaryForm as a control of the MainForm.SecondaryForm contains DataGridView which loads data from sql server and I add a collumn named SUM that SUMs all the values of the same row. This is provided within the LOAD event of the SecondaryForm.When SecondaryForm.Load events finishes, the program goes back to MainForm right after the line "SecondaryForm.Show" and here the values of the column SUM disappear.When i write those values runtime, they never disappear.
after i drag the datagrid view from the data source windows the group of controls appear in my form does not include a binding navigator, i also dont see it in the component area.
but when i try the example from northwind database after i drag datagried view it already have a binding navigator. why my own project dont?
EDIT: im able to figure out about this 1st question, just a little bit of exploration , i just add the navigator control from the control toolbox. then set the binding source. ^^,
question 2: when the binding navigator is now available.
when the navigator is already now in the form i will set the visible property = FALSE.
i will make a control button that will serve as "Save and Addnewrecord" that will save the data (from the text box )and save it to the table and add new record read to accept new data.
I have the following code to resize the datagridview but the vertical and horizontal scroll bar are not shown when there are colunns and rows exceed the width and height of datagridview objects.Bascially the following code is similar to dock to the botton, the only difference is docking to the botton change the Y position of datagridview and fill the botton section whereas my code fix the Y position of datagirdview and fill the bottom.[code]I have tried with the dg.ScrollBars = ScrollBars.Both but it it is not working as well..May i know how to get both scroll bars working.
I treid this code to draw the cells value of DataGridView on the form. but it display the three cells in the same place means: if the cells including A-B-C it didn't showed them like this : A B C
[code]For i As Integer = 0 To 2 Dim g As Graphics g = Me.CreateGraphics()
I have a DataGridview. The user has to pick an option in the datagridview. I am contemplating either putting a context menu in the DGV. I am assuming that I will fire my context menu on the Cell Enter event. However prior to that I need to draw the users attention to the column of interest.
I know I can hide all other columns but his is not userful as they need to be visible. I am also assuming that I can highlight the column in the form load event. Or I could use some sort of Call Out box in the form load event that draws the user to the column. Can you create a call out box from a context menu?
How does one learn how to fully use an API or a DLL?How does one learn what all an API or a DLL can do?What parameters does it return?Is their documentation on each one?
When I launch my application, and press the "X" button on my app, or my quit button which deploys: me.close It will not fully close the application. Like the instance is still running in Visual Studio or if you go to task manager processes you can still see it there. How would I get this to fully close?
ive coded a program with mutltiple forms and ive built it. The problem is that if i shut it down using the "X" it does not fully shut down and still uses certain files. Is there any code so i can make sure it shuts down completely?
Does anyone know when support for ASP will be fully discontinued? Obviously there no longer is development occuring on the platform, however I am trying to put together a business case as to when we should move to a new platform and make sure the timing is right for where the company will be at that time.
Its my understanding that given that it was shipped with Vista/Windows 7/Windows Server 2008, that it will be supported for 10 years past those ship dates.
i got this window is in an mdi form and the form_load event is not fully executed, im on window 7 x64 VB 2008. Here is the code of the form load event Private Sub frmGestion_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I deploy my windows application by ClickOnce deployment for first time it is updating properly. But I deploy again to the same update location it is not fully update to the client system. Some client systems has successfully update but some are NOT FULLY (sometimes partial updates happen) updated.
Back when VBStudio 2005 was the latest in .net programming, I created a program that, among other things, sets the user's system clock after obtaining certain code from time.gov and adjusting it according to a set of numbers. Due to a change in one of the websites with which the program works, it stopped working. I downloaded VB2005 Express (since I reinstalled WinXP since then and didn't feel like looking for MSVB Studio 2005), opened the source code, and made the correction. The program now works in what appears to be its entirety in WinXP. However, when it attempts to perform the function I mentioned earlier on a Vista machine, an error (a built-in error I included in the program) appears. Note that even on a Vista machine, the program does have some functionality. All requests that the program makes to access other websites is done using HTTP web requests.
I am literally BRAND new to VB, I have Vb 2010 express.I have been trying to use [code]The box literally spams, how do I make it only pop up once Also, how do I make a progress bar reset after it's been fully loaded?
the project i am currently working on has a form in it that has quite a few objects that take a couple of seconds to load. Because of that, if i simply use the .show command, the form shows up, but there are a bunch of blank white boxes where the content is still loading, how can i have the form not become visible until ALL of the contents and images inside are fully loaded?
When i run my program and then click on the 2nd btn on the top-right corner to expand to fit my screen, i find that my control are not auto align to the expand. It also has the same problem when i run my program on other monitor of different size. Is there a way to make the controls auto align?
Is it possible to open an html doc that was created by my vb 2008 application once it's been created? I have it created on my desktop, once it's there I'd like it to automatically open in firefox. I tried Using sr As StreamReader = File.OpenText(path) Do While sr.Peek() >= 0 Console.WriteLine(sr.ReadLine()) Loop End Using For starters, but it doesn't open anything. It creates the file just fine though.
how can i tell if my webbrowser1 if fully loaded with code ? i would need something like this [code] i just need a msgbox to tell me when the webbrowser1 if fully loaded
I have several files that I am reading in and 'scrubbing'. The scrubbing is simply taking certain HTML tags and changing them - no big deal.When I read in the files (one at a time), they read and then I scrub them.The files stop reading mid-way *no matter what* the encoding type There is no stop character or anything, it is simple HTML and I do not see any reason why the file isn't being read I have attached one of files that is having a problem and the code is quite simple:
Dim oRead As New System.IO.StreamReader(Dir & "" & FN, Encoding.ASCII) EntireFile = oRead.ReadToEnd()
The scenario is I would like to be able reference two similar 3rd party assemblies (e.g. assem1 and assem2) which both define a type with the same fully qualified name (e.g. Example.MyType). Is there any way to distinguish between these and refernce them seperately? I believe the answer is no but confirmation or correction would be handy. Edit: Answered for C# 2.0 and higher below but need an answer in VB.Net 1.1
Suppose I want to write a generic function that will return the fully qualified name of the data type. In other words, how would you implement the following: Public Shared Function Foo(Of T)() As String ' Return the fully qualified name of T End Function
