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?
[Code]...
i can't get the data to be shown in the datagridview
what am i doing wrong here? i think the problem starts in the ---- if then statement

Private treatments As String
Private klantnaam As String
Private Collindex As Integer

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..
View 2 RepliesI 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 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.
View 6 Repliesafter 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.

View 1 RepliesI have a weird problem (probably only to understand) why in a test app the focus rect is not shown until I press the tab key. I want to show a dialog with two radioboxes and two buttons. When I display the dialog, I'd like to see a focus rect around my first radiobutton. (So that the user can see where the focus is.) I ordered the controls and set the tabindex property from 0 to 4 so that they are in the correct order. (radiobox 1 has tabindex 0, ...). When I show the dialog the first radiobox has the focus, but it has no focus rect around it. (Until I press tab key.) I created an completely empty winforms project (Visual Studio 2010), added the controls and started it. So there is nothing special at all.
Here is the code of my sample:
Public Class Form1
Private Sub Button1_Click(sender As System.Object, _
e As System.EventArgs) _
Handles Button1.Click

I have an application with a few forms. The main form, and 2 others. When I click a button on the main form, one of the others display "attached". When I move the main form or one of the other forms around the 'attached" forms follow. The problem is that sometimes if you have another application on top of one of the forms, and click the other form, both forms dont come to the front. How can I make that happen? I've already tried things like on bringtofront for all the forms but I also don't want to take focus away and if I do that it ends up in a loop of grabbing focus via activation.

View 2 RepliesI can show/hide a form, but is there anyway for me to check if a form is hidden/shown? After the form calls InitializeComponent(), and activates the OnLoad Event, it automatically calls the Show() of the form. I do not wish my form's default startup mode to be Shown. I tried overriding onshown method and call Hide in OnShown. It works but this method looks pretty ugly to me though so is there anyway that I can stop the form from even calling Shown when it was first initialized?

Help me with this code something is wrong:
This is a program for accessing CS 1.6 and Half-Life servers with RCON password
An error occurs in Class
Thats for the form'[code...]
No errors are shown when run!
This code should get the message form server.
This error is shown:
Index was outside the bounds of the array.
Instead of the tool tips popping up next to the cursor, it would be more convenient for me to have them appear in a label on the status bar.
I've tried to myself, but had no luck. I also had no luck googling it. I mean, I could go about it in a shameful "ghetto rig" way by applying mouse overs to all the items and having them change the text in the label on the bar, but that's a waste of time.
I have a project where the user can view the print preview after finish using it. But after the 1st print preview is closed, when the 2nd time the user want to view the new print preview, the last is also shown.

I'm having an issue with an app where my NotifyIcon displays an extra icon. The steps to reproduce it are easy, but the problem is that the extra icon shows up after any of the actual codebehind we've added fires. Put simply, clicking a button triggers execution of method FooBar() which runs all the way through fine but its primary duty is to fire a backgroundworker to log into another of our apps. It only appears if this particular button is clicked.Strangely enough, we have a WndProc method override and if I step through until the extra NotifyIcon appears, it always appears during this method so something else beyond the codebehind must be triggering the behavior. Our WndProc method is currently (although I don't think it's caused by the WndProc):
Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
'Check for WM_COPYDATA message from other app or drag/drop action and handle message
If m.Msg = NativeMethods.WM_COPYDATA Then[code].....
what might be causing this or how to possibly further debug this?
