I have a DGV with the Alternating row color set to grey.In the CellFormatting event on the DGV I want to go through the rows as if a cell contains a certain value I want to set the BackColor to red.However when I do this, it just gets overridden with the Alternating grey color. The cell in question in a normal colored row appears in red as expected, just not the alternating row.
vb.net 2003 asp.net 1.1Web ApplicationI have a dynamic DataGrid with the alternating rowcolors and paging, with a textbox in each row. I need to know how to make the background color ofthe texboxes the same color as the row that they are in.

Can I create a Pen dashpattern that consists of alternating colours rather than a solid colour followed by a space? For example:
LinePen.DashPattern = New Single() {6, 4}
creates a pattern with a dash of 6 pixels followed by a space of 4 pixels. Rather than a space, I would like a different solid colour. That way I could create a rectangular cursor with something like a black/white alternating pattern, which would be clearly visible on top of any picture.
I want four rows in a row to share a color in a datagridview and alternate between two colors every fourth row. What I'm doing is this:

Some of my DataGridViewCells return the wrong value in their GetClipboardContent method. They are cells in a DataGridViewComboBoxColumn cells, so they use the displayed property, not the value property of the cell. I want it to return the value itself.An initial attempt was simply using
Protected Overrides Function GetClipboardContent(ByVal rowIndex As Integer, ByVal firstCell As Boolean, ByVal lastCell As Boolean, ByVal inFirstRow As Boolean, ByVal inLastRow As Boolean, ByVal format As String) As Object Return Value End Function in my DataGridViewComboBoxCell descendant but then I noted that this method is called more than one time per cell value, once for every data format DataGridView supports by standard, which are format="HTML", "Text", "UnicodeText" and "Csv". For csv, the base implementation appends a comma if it's not the last cell, for html it adds the correct tags depending on if it's the first/last row/cell in the table/table row, etc. I consider this format-specific, not cell-value specific.
So how could I replace the value that ends up in the clipboard without re-implementing all those format-specific aspects? That would result in quite some code for functionality that already exists in the base class, wouldn't it?
I have a theoretical class Name_Order, that has a string Name and a int Order. I need to indicate that two Name_Order's are different, if the pair NameOrder is different, that is, or name or order are different. Now, overriding Equals no problemo, but I have some "issues" with GetHashCode:

I have a main class that has a Sub procedure with no implementation. Any derived class should override and implement this procedure, so I used MustOverride in the base class.
Now, any time this procedure is called, I need to set a specific Boolean variable to True at the beginning of the procedure and set it to False at the end.
Is there a way to avoid writing these two lines of code in procedure implementation of every single derived class? Can I set this value to True in the base class, then run procedure in the derived class and then set the value back in the base class?

At run-time after creating the DataGridView instance and bind the data I do the following:

rticularly when creating jQuery buttons with no text and just icons) as a result of this.Secondly I am attempting to create my own custom button output by overriding the Render() event and am having a bit of difficulty trying to understand how to go about changing the output that is provided by this event.If I look at the HtmlTextWriter that is provided as the parameter to the Render() event I can see it contains a protected property TagKey = Input {47}, is it possible to simply modify this property somehow and change it to a Button or do I need to create a new instance of the HtmlTextWriter and populate it all from the start? If so, could anyone provide some guidance as to how this would typically be done and if there are any special considerations I need to make to ensure that my derived button class is functionally equivalent to the original (excluding the html)?
