GridControl - How To Get Total Number Of Master And Grouped Rows
Jan 25, 2012
I found out how to keep track of the currently expanded grouped rows by using 2 events:
- gridview.GroupRowExpanded
- gridview.GroupRowCollapsed
Where I increase or decrement an integer that keeps track of how many group rows are currently expanded. I am now tackling the problem of what to do if the user expands or collapses all of the group rows. I currently know when this is done by checking the e.RowHandle. Any way to find the total number of groups rows currently in the GridView (something like rowcount for normal rows) so I know how many to set the tracking integer to.
For Example: If my current count is 2 and the total number of groups are 15 then when the Expand All is fired the current count is set to 15 rather than 3.
I am currently using DevExpress 10.2 within Visual Studio 2010. In a previous question I was trying to print the current user view of a DevExpress GridControl with the user's choice of expanded or collapsed master rows and/or group sections. I was told this was not possible at this time. I have now decided to use the following code:
i have a Janus grid, which has two columns and the rows are organized in a hierarchical order i.e. parent and child rows. One of the columns in the grid is grouped (by dragging the column in the group by box above the grid). I have a cell-changed event that is fired when a cell content is changed. I do this in the cell-changed event:[code]If i change the value, in a parent row, of the grouped column then the child rows are set to Nothing. After the last line in the above snippet, child rows of row are set to Nothing. On the other hand, this problem does not occur if i change the value of the other column (which is not in the group by box). The problem occurs only if i group a column and change its value not otherwise.
I want to get the total of ROWS IN A TEXTBOX I MEAN LIKE THIS
quantity price subtotal 10 * 10 100 15 * 1 15 8 * 10 80 this is a exam. so the total OF ( 100+ 15+ 80 = 195) To be shown in the texTbox named" TOTAL " and so .with the other rows till unlimited if is possible
I am trying to count all the rows on a datagrid after it has been populated from my DB. I have searched online on how to do this but nothing seems to work.[code]where test is my datasource it gets thrown into
Dim Subject As String Subject = InputBox("How many") Dim i As Integer Dim num As Integer
[code]....
So how do I get the total of num into a textbox? If I type in 3 for "Subject = InputBox("How many")" then I get 3 "num = Val(InputBox("This many"))". Only the last number entered goes into the textbox and they don't add up to make a total.

I've just converted a project from .net 1.1 to 3.5, and I'm being given loads of warnings in the error list. The program compiles and runs ok, but I think I should probably try to at least reduce this large number of warnings.The trouble is that the error list only tells me about the first 102 warnings. Even when I fix one, the number stays at 102. So I have absolutely no idea how many warnings there actually are. If there are 150, I'd like to get rid of them. But if there are 10,000, I don't have the time to fix them all.Is there a way to see the actual total number of warnings?
on my design i have a listbox, datetimePicker and a button. how do i pick a date like for example 14 feb 2010 from the datetimePicker and click the button, then the listbox showing how many days from 1st jan 2010? should be 45days.
Let's say, for example, this is a quiz where the answers are already loaded into a database from different students. Inside of the table with various student entries containing various student's answers there is a row "masterentry" with all of the correct answers.
What I would like to do is code a button that will pull the master row on click and compare every other row against it. Starting with the first row, every time the column matches the master entry 1 point is assigned to a declared integer. When the row has completely been read the integer is stored in a "totalpoints" column. Then it moves on to the next row of answers.
i need some help here, i want a result that shown a total number from student who passed some subjects. Let say there are 8 student who got A in subject chemistry, then the output should display result something like " there are 8 students who got A in chemistry". And also is it possible to combined the result, for example i want the output something like "there are "X" students who got A in chemistry and physics". where "X" is variable (number). it should trigger when winform is loaded. im using bindingsource.filter, but failed. because using bindingsource.filter need the input from user then it produce the output. whereas i want the result shown when the winform is loaded. How can i achieve this.
I've added a button to my windows form and I want to have it where every time I click on that button it registers the click and displays the total number clicks in a textbox on the form.

I am using MS-SQL and I am trying to write a query which fetches rows from the master table and related rows from the detail table. Now, the thing I want is that it must only fetch the first row from the master table and related field from the detail tables should be blank in that first row, now if there are related rows found in the detail tables, they must be shown in the separate rows. I have been trying using the following query but it is not giving the desired result.
I am trying to keep track of the total number of discounts given (whole numbers) I keep getting .75 after the first discount, and it adds .75 for every trans action after that. I have tried to pick it apart but I just don't see it. You can follow by tracking the comments that relate to the summary. I know that is an Integer but the book has it declared as a decimal so I went with it.
Public Class BookSaleForm 'Declare module level variables Private QuantitySumInteger, SaleCountInteger As Integer Private DIscountSumDecimal, DiscountedPriceSumDecimal As Decimal Const DISCOUNT_RATE_Decimal As Decimal = 0.15D [Code] .....
How do I code the total cost to give me a pound sign with the total cost at the moment when the total comes up for an example it gives me 3.6 when I need it to show £3.60 here is the code I have so far. [code]
I have an application that has 3 list boxes, one selects a workshop, the other a location. the third is to display selected costs.to do the calculation a loop is required. i have written the code but when i calculate the cost the final result to be displayed ends up as being the cost of the last work shop and location * 3,What is supposed to happen is the location is multiplied by the number of days(3 in this case) and added to the workshop cost.the loop is supposed to add all cost from the list box till all have been added.what is happening is the calculation goes to the last entry as stated the multiplys this total by number of days(dbl)?
I am using DevExpress GridControl to display information from my database through a stored procedure (ie. SELECT * FROM aTable). Unfortunately when I run the program it doesn't display any of the information, columns, etc. It displays an empty table. I know that there is information contained by the GridView though as I have print statements that return the row count. Specifically:Console.WriteLine(GridView2.RowCount) ' returns the number of rows that should be displayedConsole.WriteLine(myTable.Rows.Count) ' returns the number of rows that should be displayedWhat should I do so that the actual data within the table (DataTable) and the DataView is displayed to the user. I know the row count is correct as when I add/remove a record the row count correlates by incrementing/decrementing.
