C# - Show Percentage By Specifying DefaultCellStyle.Format Value In Datagridviewcolum
Nov 13, 2009
With datagridview.Columns("PricePerUnit")
.ValueType = Type.GetType("System.Decimal")
.DefaultCellStyle.Format = "C"
End With
A datatable is bound to the datagridview and in the above code a If I just add row with a value five to the column "PricePerUnit" it will be shown as $5.00 in the datagridview column Similarly I want to show up something like If I just add row with a value five to the column "DiscountPercentage" it should show as 5.00%
I am using VS 2005 pro and VB.NET. How do you format the DataGridView.DefaultCellStyle.format property for zip codes and phone numbers. I have a zip code and phone number column(s) that I want to be formatted. I have tried a lot of different things:
Zip code: "99999-0000" or "Phone Number: "(999)000-0000" or "(000)000-0000" and the like So far nothing has worked. I can get my date columns formatted correctly, but not these. Can any one give me some examples that work?
I use an unbound datagridview. In the columnscollection i have set the format in the DefaultCellStyle to "N2". In the datagridview cellformatting-event i have also placed the e.Value = CDec(e.Value).ToString("N2",System.Globalization.CultureInfo.InvariantCulture)When i edit a cell in the grid, and put a number (p.e. 15) in it, it will be presented as 15,00 (just the way i wanted).I can change the number to another number without a problem.But when i clears the cell i get an error with the code in the cellformatting-event: "Conversion from string "" to type 'Decimal' is not valid." Probably the value is changed from a decimal number to a string. How can i clear the cell without getting an error?
i see that i can use defaultcellstyle.format to format a column but what if i have an number stored as a string "0511" and i want to display it as a integer "511"
I'm using VB 2008 and reading data from an access 2003 database.I have a query setup in access - read in as a 'view' in vb ... that is showing results of first pass yield. total good parts... total bad parts... and percentage of yield.in my access query - i have the percentage displaying properly using the column format in access... however - on my form - the data source comes in as a textbox...by default.I can't seem to google the right question - but right now on my form, even though the dataset recognizes it as a double precision number - the option in the datasource tab - shows it as a text box or data grid right ...
so on my form i have the text box or details option... but my text box shows the percentage as a long decimal ... .98936524 or whatever... what's the correct string i need to format the textbox.text to display a percentage?I tried format(val(textbox.text), 0.00) that didn't do anything... and I did this under the form load section after the data sets were filled.
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 need to format a Label to show numbers in a certain way. I had asked this before about textboxes so I looked into that first but it didn't do what I wanted.
i have a calculation and the results are outputting like so 96.5471447543161 i would like to format this text box to only show 96.54 (no rounding) below is the code i am using.
Dim d1 As Double = Nothing d1 = ((Val(Me.txtgoodsout.Text) + (Val(Me.txtnrft.Text))) / Val(Me.txtrawin.Text)) * 100 Me.txtyield.Text = d1
I'm trying to format a datetime field to just show the date. The datetime is bound to an asp:label and for the Text attribute I have tried the following....
In all cases I get a green wavy line under the equation and the tip help says "Validation (ASP.Net): If this attribute value is enclosed in quotation marks, the quotation marks must match. String.Format("{0:D}", DateTime.Now) is the syntax that I have been told should work.
I have the following problem.I read an rtf. text file with my vb program and I put the contents of the file to a richtextbox.The characters in the file are Greek e.g αβγδ and the characters in richtextbox appear like this 0000.How can I show the characters from the file to the textbox in the same format?Is it about globalization?
I am using the following code to display a timer. I have no use for the hours, is it possible to format the string to show only MM:SS? Me.lblTime.Text = String.Format("{0}:{1:d2}:{2:d2}", remainingTime.Hours, remainingTime.Minutes, remainingTime.Seconds)
i have a column item-code, inside my database which i have bound to a datagrid view. 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. I tried defaultcellstyle.format but don't know how to get a substring for it.
I am a bit new to crystal reports even though I've been doing a bit of heavy lifting with it.I have this crystal report that has a datetime field.This field has a default datetime of 1753-01-01 00:00. Now I want this field to display only date like "01-03-2011" and also anywhere it sees the default date, it should display an empty string like To achieve this I used this formular (in the display string)
if CurrentFieldValue = DateValue('1753-01-01 00:00:00') then '' else totext(CurrentFieldValue)
This successfully changes the default date to empty string. But now I can no longer change the format to dates only.
I'm using stream reader to read some text(txt format) n show in textbox1. I want stop at the second last line to get the string.Below is my code:
path="c:dic.txt"Dim reader As New StreamReader(path)Do While reader.?? //how to instruct to stop when read until second last line,because i don't know how many lines in the text file??
I am trying to get a percentage that just does not seem to work.I am using WMI to get the Total Physical memory of my system and then the Free Physical Memory. Then get the percentage.
2147483648 - Total Memory 838028 - Free memory
According to Task Manager my physical memory is 59%. This is the code I am using but I can not get 59% or 41% that is free.
I have a program that is calculating the cost of a certain number of plane tickets, the validation and basic calculations are fine the only problem i've got this: There is a discount text box field called "txtDiscount" where IF a user enters a number it will discount this as a percentage off the total cost of all the tickets, but I cannot get it to work [Code]
I have a fixed percentage 0.3% I need to multiply this by a number of months which varies 1 to 12
Having done this I need to add the percentage to a pre-determined number
so as an example
£300 + (0.3 * 10)
I can get the 3% (0.3 * 10)
But when I add this to the existing number (£300) it equals £303 not £309 which is what it should equal.
Can anyone advise the way of adding a percentage as appose to just another number? This also need to allow for -percentages i.e. -3%
The equation I am using is below and I appreciate there is nothing to set decTotalPercentage as an actual percentage but that's because I am stumped...
I have a problem regarding an access file I attached to this post.I have a table which contains the costs(VVGK) for each month in 2008, 2009 and 2010. For each month we have planned costs(Plan) and the real costs (Ist). And what I want to realize is that in the report in the top right it automatically displays the percentage difference between the plan and real costs of the last month. And this should then be automatic every time I give new input(new month, new VVGK Ist).
I'm developing a data logging application using VB for the actual logging to a MySQL database. I'm reading a value from a device and then running an insert query every minute. This is great but if the value doesnt change all day then my records are going to all be the same. I'd like to try and calculate the percentage of change on the value and only run the insert query if the percentage of change is greater than, say 5%.
I need to compute the percentage of games won and games lost. I keep getting errors and it's driving me up a wall. I've changed my code so many times that I don't really remember what it was like when I started.
Private Sub btnPercentage_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPercentage.Click Dim team As String
I am attempting to draw and fill a rectangle using percentages passed through the text properties of 4 textboxes. I am attempting to do this in VB 2008. For example:
textbox1, 15%, green textbox2, 35%, blue textbox3, 40%, red textbox4, 10%, orange
I have data coming in to my serial port, which is just a 6 digit number. textbox1.text = serialport1.readline() In the textbox_text_changed sub. I need to do something with this number, but only if it has changed by more than 2%. I need the 2% as the number coming in is fluctuating a little bit so I don't want anything triggered if it's less than 2%.
