Apply Percentage Format To Custom Cell In Custom Column In DataGridView?
Jun 25, 2009
I came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.

I believe that my questions are all going to revolve around the internal workings of DataGridView.While this is specifically written in VB.Net, it is definitely a general Visual Studio object question generically related to anyone working with .Net.I've been trying to find a forum where I can get some interaction and help to move forward.Microsoft's websites seem to be all questions and no answers.
I'm using VB.Net under Visual Studio 2005 SP2.I need to have a DataColumn that is dynamically visible based on other data in the same DataRow.After a lot of unsuccessful testing with various methods of accomplishing this, I came across the concept of Custom Cells/Columns.I started with several slightly varying examples and everything seemed to be falling into place. I tried to research each property and attribute as I incrementally learned a lot about the internal workings of Windows controls in general and DataGridView in particular.
The confusing symptom is that as I scroll down through the grid, the painting of the custom cells is at best unreliable.I created a minimum test case to eliminate as many variables as possible and I combined all of the source into one Form1.vb as follows:

I have created a custom column type for a datagridview. I have created a class for the datagridviewcolumn and a class for the datagridviewcell. Within the datagridcell class I am using the following code for the font.Dim fnt As Font = parent.InheritedStyle.Font How do I change this so that I have control over the font color for that cell? I am fine with the font just not the color.

I'm trying to show a custom contextmenustrip on my datagridview and it works fine except when the cell is being being edited. Then it shows the default windows contextmenustrip with copy/cut/..Is there a way to overwrite the DataGridViewTextBoxCell contextmenustrip or disable it? The solution from Disable DataGridView System ContextMenu does'nt work for me.
Private Sub DataGridView1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DocCostGroupDetsDataGridView.MouseDown
If e.Button = Windows.Forms.MouseButtons.Right Then

I am trying to display a custom control in a datagridview cell so that I can show nicely formatted information.
I am quite comfortable with the use of datagridview control accepting a list of objects as its datasource. I am also comfortable with populating the cell contents in the cellformatting event.
So I am planning to, instead of using a normal textbox control, button control and linkedtext control in datagridview cell, display my own custom control which is good one for displaying some custom data like, name, address, telephone, photo and others. It would be a nice improvement in my application.

Well, the title pretty much says it all. I have a user control that is a a collection of six label controls. three are used as visual color indicators, and the other three are used as the corresponding value for each color indicator. (It's sort of like a legend key on a chart or map.) I have created a custom class to store the three values, and the associated methods to interact with the values. (I can probably use a structure instead of a class, but right now, I don't want to discuss that.) My problem, is that I want to show my user control inside a cell of a DataGridView. I've looked at the examples that create a MaskedTextBox DataGridViewCell, but I can't seem to get it to work. Here is what I have:

I've been trying to customise a datagridview but no luck so far, thing is, i want some of the cells to not have the same grid colour and width as all the rest of the grid. Do you guys know how can this be done? I know it is possible cause i've seen it before but i have no clue how to accomplish that.

I have added a custom Control to my project, but every time I edit it and rebuild the form that I use the custom control in adds the project name in front of the control and won't compile. i.e. Project name = MyProject, Custom Control name = MyControl. When I rebuild the project after editing my control I get an error, MyProject.MyControl doesn't exist. If I remove the MyProject from the line it compiles and runs fine until next time I edit the custom control.
I can't figure out what I would be doing wrong to cause this, or why it is putting the project name in front of the control, but then not accepting it. I am also struggling figuring out how to change the back color on an individual cell in an Datagridview Combo Box. The style.backcolor property of the cell doesn't seem to do anything.

I'm trying to create a custom DataGridViewColumn and DataGridViewCell, and have found this article to be a great resource. I'm done creating the DataGridViewColumn class and the DataGridViewCell class, however, when I try to edit the type of the column, my new custom classes don't show up as one of the options. My DataGridViewScheduleColumn inherits DataGridViewColumn, so I'm not too sure what I'm doing wrong. Is there anything else I need to do to expose these classes to the IDE?[code]...

The item-code comes in this format "A-B-C", i wish only to show the "B" part of the code, i have bound this column to the gridview and now wish to make it show the substring.

In DGV, if the contents of the cell is truncated, the DGV shows ellipses (three dots) (...); but as the font is set to a Gujarati font, it displays a Gujarati alphabet "ઈઈઈ" instead of "..." because the Gujarati character "ઈ" is coded with the English "." (dot) character.In Gujarati font, "." can be generated with the English character "P".So, How can I change the ellipses to English "P" character? OR How can I remove the ellipses completely?I have found a similar solution by berc on Tuesday, August 31, 2010 1:33 PM :but I am not sure it is the perfect and/or the only way to do so, AND it will really work or not

I've used the following code, taken from here, to create my own custom column for datagridview, so that I can now have images and text in the same cell:

It works very well, except that the image that I use is right at the edges of the cell. I'd like to give it a small margin. How can I do this?

This will sound an unusual question but I'm looking to find a way to reduce the number of colours of an image in a PictureBox from 1,000's to 15 and then apply a custom palette of 15 colours using a closest fit algorithm...
My graphics are never larger that 64x64 pixels generally, so the processing power / overhead needed to perform this operation is relatively small!
The inital algorithm I wrote is very slow and requires me to loop every pixel in the image and loop my palette doing a comparison to find a best fit colour.
Finding a decent method to do an initial colour reduction would be great!
I wondered if there were any inbuilt VB commands for PictureBox, etc that could be used to aid me in doing this...

I 'd like to enable the user to apply a custom filter to a System.Data.DataTable.At the moment I have a very simple function like this:
Dim result = dataTable.Select(txtUserInput.Text)
With the filtered results I'd like to do further operations(e.g. Database Update/Delete).Is an sql injection protection needed or is the "Select" function secure?
//Edit:Can the "select" function be abused to manipulate any data in the datatable, execute code, ...? If the only danger is that this function can return to much/to less data there is no problem. But if the data in the dataset gets corrupted it's a real problem.

The bottom line on a dropped-down datetimepicker shows the date different then in the text-part.In my case, the text-part format was yyyy/mm/dd, but the bottom part of the dropped down part stated Today: dd/mm/yyyy, what is probably the format set in the regional settings.

I want to format the Timespan to have format like this 49 hr 34 mn 20 sec
I used the String format below :
String.Format("{0:00}:{1:00}:{2:00}", theTimeSpan.TotalHours, theTimeSpan.Minutes, theTimeSpan.Seconds)
It formats the Timespan to this format 49:34:20. How can I add hr mn sec to the String.Format above? or there's another easy way?

What is the right way to use a custom format string on .e.g a zip code?
The zip code in the database might have 9 characters, but the program should only output five. Using string.format("{0:#####}","322318825") will output "322318825", the entire 9-digit code.
Zip codes are only an example. This is actually for a dynamic format function that takes two arguments, one is the format and the other is a database field value. Therefore, it cannot work by being strongly typed.

Code:TimeTo_dtp.CustomFormat = "dd/MM/yyyy - HH:mm:ss"This works fine, but what I also want is for the the user to be able to select their time more precisely using miliseconds. After searching around I came across this web page:It has all the different formats on there. If you scroll down you will see format 'f' then format 'ff' then format 'fff', 'ffff', 'fffff', 'ffffff', 'fffffff.'What I am asking is how do I use that in my example?
I tried

With String.Format() it is possible to format for example DateTime objects in many different ways. Every time I am looking for a desired format I need to search around on Internet. Almost always I find an example I can use. For example:
String.Format("{0:MM/dd/yyyy}", DateTime.Now); // "09/05/2012"
But I don't have any clue how it works and which classes support these 'magic' additional strings.So my questions are:How does String.Format map the additional information MM/dd/yyyy to a string result?Do all Microsoft objects support this feature?Is this documented somewhere?Is it possible to do something like this:String.Format("{0:MyCustomFormat}", new MyOwnClass())
