Is there any way to create a total row at the last of grid view without using loop
I mean if I want to get the sum of a column of a datatable then can I do it without using loop.
However in my opinion they require a lot of prior knowledge on how to programatically refer to each item.
Does anyone have a link to or can create a relatively basic example of how to achive a running total in the footer for an ASP:Gridview?
How to apply for loop on grid view and to check the empty cell value then show a message...
Dim cnt As New DataSet1.LibraryDataTable
For i As Integer = 0 To cnt.Rows.Count - 1
For j As Integer = 0 To 5
If GridView1.Rows(i).Cells(j).Text = Nothing Then
GoTo e
ElseIf GridView1.Rows(i).Cells(j).ID Then
GoTo a
End If
Next
Next
e:
lblmsg.Text = "he is not return a book"
a:
lblmsg.Text = "he is return all book"
I am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.
What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).

How to create a Filter in Data Grid view.
View 3 RepliesI have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?

View 5 RepliesI am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.
This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.
1) I would like to see in my spreadsheet the following by only select the network drive n:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105
2) I would also like to know if this is the faster method.
3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.
4) I would like to see the folder name, size of folder and count of files in the listview.

See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

i have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.

View 3 RepliesI am trying to filter a dataset by adding together numbers within a specified field (say field1) within the dataset until i reach a specified number.
The filtered dataset should either be precisley equal to the number or most likley less than. In short if a row exceeds the number it should revert to the previous record.
I have no probs with general filtering and using data adapters to access the data. But im struggerling with the loop side of things.
I have a class project that I have been working on for a while, and I can't figure out how to add each cost from lstCosts together to show a total cost of the selected workshops in lblTotalCost. Using the current loop that I have, it only adds the last cost in lstCosts. Is there a way to add the indexes together?
Code:
Public Class Form1
' The registration fee for each workshop
Const intSTRESS As Integer = 595 ' handling stress
Const intMANAGEMENT As Integer = 695 ' time management
Const intSKILLS As Integer = 995 ' supervision skills

I have a grid view which uses SQL to calculate information that I need! I want to put this calculated total into another table in database.
SELECT StaffDetails.StaffID, SUM(HolidayRequests.RequestTotalDays) AS Expr1 FROM HolidayRequests INNER JOIN StaffDetails ON HolidayRequests.Username = StaffDetails.UserName WHERE (StaffDetails.StaffID = @staffID) GROUP BY StaffDetails.StaffID, HolidayRequests.ApprovalStatus HAVING (HolidayRequests.ApprovalStatus = N'approved')
It basically calculates the total number of approved holiday requests for a staff member which is correct. I want this number to then update the HolidayTaken field in another table each time a holiday is approved.

View 1 RepliesI wanna ask something regarding the updating of database.
basically i am doing in 3 tier.
and i have a database table called 'SchoolTalkAppt'.
in the table itself, i have 1 empty column which i will be filling in using update statement.
the other columns are already created and filled into the table earlier.
i just have to update the 1 empty column (FirstName) and ALSO update the Status from 'pending' to 'Assigned'.
i decided to use drop down for both the name and the status.
the names available in the drop down i would be retrieving it from another table and populate it inside..while the status i manually added 2 options, 'Pending' and 'Assigned'.. not retrieving from database.
Since i am only required to update the FirstName and Status, in the update statement i put in the update for FirstName and Status only.[code]...

View 5 RepliesI have a FlexGrid control in my Windows application that contains a row of data. The data in this row is related to even more data that won't all fit on the same row. For Example:The main data row contains Username, Last Name, First Name, Middle Name, E-mail Address, Phone Number, etcA secondary row to this might contain user permissions to certain resources, such as File Server Access, FTP Access, Remote Access, etc.Now, I can use the subtotal and outline capabilities of the VSFlexGrid to make a second row, but the column widths are still bound by those set for the main data row. Additionally, I can't put real "headers" on the supplemental data. I have to fake it by creating an additional row, setting the background color of that row to gray, putting the header strings into those fields, and then adding the next row with the actual details.
What I would like to do is create separate grids for these secondary rows and "embed" them in a blank row of the existing FlexGrid control directly under the related main data row. This would give me the ability to use a different number of columns, to format these columns independently of the "parent" FlexGrid settings, as well as put a new header row for the new grid that identifies its data.In other words, I'd like to somehow make a "child" grid that's related to a particular row of the "parent" grid (not the entire grid itself). I don't know if this is possible, and if there is another way for me to accomplish this goal, I'm all ears. However, if it IS possible, I'd love some advice on how to implement it.
