• mu2 Translating DataGridView row index to a DataSet row index

  I have a sorted DataGridView and I need to make a change to the DataSet that is bound to the DataGridView. Here's the code I'm using: void DataGrid_CellValueChanged(object sender, DataGridViewCellEventArgs e) { BindingManagerBase bindingManager = null; bindingManager = DataGrid.BindingContext[DataGrid.DataSource, DataGrid.DataMember]; DataRow findRow = ((DataRowView)bindingManager.Current).Row; int datasetIndex = DataSet.Tables["table1"].Rows.IndexOf(findRow); } From what I understand, the IndexOf() method should take the row and find the index of it in the dataset. My problem is it's always coming back as 0. Can anyone see a problem with my code. Thanks! I know this has to be a common problem...people bind dat ...Show All

• PatrickCairns controlling the focus

  Hi. Does anyone know how can I make a control work without recieving the focus The thing is that I'm trying to simulate a kyboard (on a UserControl) which is added to a form. Whenevet a key is clicked, I use the SendKeys.SendWait method to simulate a keystroke. In order to process the simulated keystroke, the recieving form should be in focus. To achieve this, I use the SetFocus API function with the handler of the recieving form. So far so good - it all works fine except for the slight occasional control bar flicker when changing the focus. So - is there a way to avoid all that focus transfer You'll need to give up on SendKeys if you want to avoid the focus problem. You could send the WM_KEYDOWN and W ...Show All

• CodieMorgan Add a DataGridViewComboBoxCell to the Insertion Row only

  I can add a DataGridViewComboBoxCell to a row in my DataGridView. I want this only to be added to the Insertion Row.. New Row.. Row with a star in front of it, whatever you call it.

• bikerchick Leftover pixels From DrawReversibleLine

  I am creating a drawing program...  When I draw a line I am capturing the mouse, and drawing a reversible line, which I store and redraw (to erase the line) if the mouse moves to another point.  The last line will be the the one I capture on mouse up. This works, except there are a few remaining jagged edges created during the process.  They all disappear after mouse up, but they are anoying anyway. Does anyone know how to fix this   When I have done this in the past against the Win32 API, it was very clean, and I am looking for that cleanliness. Do I have to use the API calls Thanks, Bob Thanks, I'll look into it. And it still might be a bug. It really helped to tal ...Show All

• Pedro Martins Color attributes with checkbox.appearance=appearance.button

  After my checkbox has been set to have the appearance of a button, it does not respond to the setting of backcolor attribute. How can I fix that Hello, Thing is this should work. I tested it by doing the following and it worked fine using VS2005. 1. Created a new project. 2. Dropped a CheckBox onto the form. 3. Changed its appearance to Button via the property dialog. 4. Changed the back color to Red. Everything worked fine. There is probably something in your code causing the issue. I'll throw out the "Clean your project and do a complete build" spiel, but I'm not sure that would help. Ken Thank you, Ken. I did what you suggested and it w ...Show All

• Kmad Creating Flat Tabs

  Hey there, I'm working on an app that has one tabControl component, and which has a bunch of tabs associated with it. I noticed that in the properties for buttons you have the option to control FlatAppearance. However for the tabControl, there is no option to display the tabs flat (like that you see in Excel and Visual Studio). Its a nice look imho, and I'd like to implement it into my app. I was poking around the MSDN library to come up with something that could control the look of the tabs I found the VisualStyleRenderer.DrawEdge Method public Rectangle DrawEdge ( IDeviceContext dc , Rectangle bounds , Edges edges , EdgeStyle style , EdgeEffects effects ) Does anyone have any experience with this metho ...Show All
