backcolor

问题 I have DataGridView on my form application. After retrieving data from a table in the database and displaying them in DataGridView , I apply a green color to some cell's BackColor of the rows if a certain condition is met. After those cells are colored green , the program makes them go through another condition, which colors the whole row's BackColor red if they fail to satisfy the condition. However, it seems like pre-colored cells cannot be overwritten with a new color. Even if I apply the

问题 What I have is a Windows form, in C#, with 7 text boxes. Each text box updates 2 or 3 others when its value is changed and accepted. What I want to do is somehow take those text boxes that need to be updated and make them "flash" with a light back color or something.

I can use a timer, a while loop, and a back color with a

问题 I have a button which I wanted to "flash" briefly to get the user's attention. I figured the easiest way would be to change the Button's BackColor property to another color, and then switch it back again. So I do something like this: this.oldColor = myButton.BackColor; myButton.BackColor = Color.Blue; and then after a about 1/2 a second: myButton.BackColor = this.oldColor; But the button's background color end up being distinctly darker than the rest of the buttons on the Form! At first, I

问题 I took an html table that I am applying alternative row colors to, and I added jquery table sorter on it so users can sort the table. The issue is that the alternative row colors are all messed up now as (based on the sorting) there are multiple rows with the same background color. Is there any way to reset the alternative row color with jquery table sorter? 回答1: There's already a default widget zebra , built into the core, which applies the classes odd and even to alternate rows. It works

问题 After having done some research, I believe I am asking the same question as Remove richtextbox SelectionBackColor. I have encountered the same issue, but I believe the answers in that thread were insufficient as the question was not clearly explained. Please see below: In a RichTextBox , how do I remove a custom BackColor from some, but not all, of the text ( SelectionBackColor ) so that it assumes the BackColor of the control even if that BackColor changes in the future? I have a method that

问题 I have Problem with changing rows color in Windows Forms. I did it with Columns and tried the same for Rows but it didn't work. Can someone show me how to do it?

问题 OK, someone please tell me why this is not working. I have a simple MenuStrip in winforms app (c#). It has ToolStripMenuItems. In the properties window of the designer, I select BackColor = White. In Desginer.cs file I can see it. Running the app, the background color is Control (grey). What is going? Why is the backcolor not white? Thanks EDIT This is the code from the Designer.cs: this.menuRefresh.BackColor = System.Drawing.Color.White; EDIT2: In the code, after loading the form (in the
