Re: Draw rectangular - C# Discussion Boards

You're probably using CreateGraphics ? Don't.

You have two options.

1 - draw your own image and draw a box over it
2 - draw a box onto the image itself

If you're trying to draw a selection rect with the mouse, then you need option 1, so you can draw above the image, instead of onto it.

query regarding onmouseover event

12-Sep-06 23:32

Please, go back and actually READ my response. NEVER use CreateGraphics unless you know exactly what it does, and it's what you want it to do. CreateGraphics could be used for this selection box, IF you didn't use a picture box. But the picture box is being invalidated, and so your box is being deleted. Either way, I prefer not to use such expensive hacks, I draw it all in my paint method.

tab control for web applications

12-Sep-06 23:02

You can't. You're using HTML, not server controls, so there's no postback and no event being generated for the code behind. You can do it all on the client, or you can change it to use server controls.

There isn't one, but it's easy to write one, it's just a control that sets which tab is selected and draws it differently, and draws the others as links. There's probably one on CP.

Isn't matlab C++ ? Your best bet for .NET interop would be C++/CLI, there's no way to convert C++ to C#.

Here u go,
U cannot directly create a DropDown column in the datagrid, u have either extend the datagrid or create the ComboBox using the template columns.
Here are some links that will help u.

http://www.c-sharpcorner.com/winforms/ComboBoxInDataGridSKJ.asp

http://www.codeproject.com/cs/miscctrl/DataGridZen.asp

http://www.codeproject.com/aspnet/ASPNET_DataGrid_creation.asp

the second one is good and simple

Hope this helps u.
