.net - Show A Selection Border Rather Than Back-colour In A DataGridView?

Jun 15, 2009

My DGV has row BackColors set to various colours based on business logic. When a user selects the row the colour changes to the selected row BackColor thus obscuring the pre-set colour. I would like to preserve the original colour when a row is selected and indicate selection with (perhaps) a bold border around the selected row.

EDIT :To make it clear, this is a WinForms app.

Nov 28, 2009

Is there any way to change the default colour to the highlight when a listview row is selected? Apparently the default blue colour causes some problems for some users who have some visual eyesight problems. They didn't tell me what colour they wanted but they did indicated the blue is annoying.

Html - Regular Expression From Font To Span (size And Colour) And Back (.NET)?

Mar 26, 2010

I am looking for a regular expression that can convert my font tags (only with size and colour attributes) into span tags with the relevant inline css. This will be done in VB.NET if that helps at all.I also need a regular expression to go the other way as well.To elaborate below is an example of the conversion I am looking for:

<font size="10">some text</font>

To then become:

<span style="font-size:10px;">some text</span>

So converting the tag and putting a "px" at the end of whatever the font size is (I don't need to change/convert the font size, just stick px at the end).The regular expression needs to cope with a font tag that only has a size attribute, only a color attribute, or both:

<font size="10">some text</font>
<font color="#000000">some text</font>

[code]....

I also need another regular expression to do the opposite conversion. So for example:

<span style="font-size:10px;">some text</span>

Will become:

<font size="10">some text</font>

As before converting the tag but this time removing the "px", I don't need to worry about changing the font size.Again this will also need to cope with the size styling, font styling, and a combination of both:

<span style="font-size:10px;">some text</span>
<span style="color:#000000;">some text</span>

[code]....

I am extracting basic HTML & text from CDATA tags in an XML file and then displaying them on a web-page.The text also appears in a rich-text editor so it can be edited/translated, and then saved back into a new XML file. The XML is then going to be read by a flash file, hence the need to use old-fashioned HTML.

The reason I want to convert this code is mainly for display purposes. In order to show the text sizes correctly and for it to work with my rich text editor they need to be converted to XHTML/inline CSS. The rich text editor will also generate XHTML/inline CSS that I need to convert 'back' to standard HTML before it is saved in the XML file.I know the temptation will be to tell me a number of different ways to set up my code to do what I want but there are so many other permutations I haven't even mentioned which have forced me down this route, so literally all I want to do is convert a string containing standard HTML to XHTML/inline CSS, and then the same but the other way round.

Asp.net - Dropdownlist Autopost Back Remembering The Selection?

Jul 25, 2011

I would like to change the dropdown list and whenever I make some changes it should auto post back and triggers a selectedindexchanged event for drop down list.

Colour Picker Scanning - Log On Method - Users Selecting A Colour From A Paint Panel

Mar 15, 2012

To .NET after getting tired of using VB6 due to the lack of functionality. I'm trying to create a log on method for a system which will involve users selecting a colour from a paint panel and then placing/drawing the colour in 1 or more tiles of a grid, basically a 3x3 grid in which for example they selected the blue colour and drew in the top left tile and the bottom left tile. The logon is selecting the correct colour and placing the colour in the appropriate tile. What i want them to be able to do is place even a single pixel of colour so it has a high accuracy. So far i have a timer which loops from the width of the grid to the height of the grid.

Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Dim BMP As New Drawing.Bitmap(1, 1)
Dim GFX As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(BMP)
GFX.CopyFromScreen(New Drawing.Point(MousePosition.X, MousePosition.Y), _

[CODE]...

To start with i have just hard coded the colour i want it to detect. At present it produces an error. Parameter must be positive and < Width the error is on System.Drawing.Point(i,j). If i place the mouse over the colour then run the program it will say it has been found, but otherwise it wont find the colour. I believe i am not updating the location of the pixel or something to that effect.

Make The RTB Not Show The Selection Right From The Start?

Mar 6, 2012

When setting the selection of a RichTextBox, the selected text is highlighted even though I set the HideSelection property to True. Once the RTB loses focus then the selected text is no longer highlighted. Programatically setting the focus to another control doesn't hide the selection, only physically clicking another control will hide it. So is there a way I can make the RTB not show the selection right from the start?

I'd like to replace all the white pixels in a bitmap image with pixels of the colour "Color.FromKnownColor(KnownColor.MenuHighlight)". Is there some method in the Image, Bitmap or Graphics classes I can use, or will I simply have to inspect each pixel in the image with GetPixel, check whether it is a white pixel, and then set it with SetPixel?Here is the code I am using now:

Private Shared Sub highlight(ByVal b As Bitmap)
Dim highlightColour As Color = Color.FromKnownColor(KnownColor.MenuHighlight)
Dim whiteARGB As Long = Color.White.ToArgb
