Getting A Value From A Grid View Into Database?
Mar 13, 2012
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.

I 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?

I am using a data grid view to display information from a database and I can't get it to update correctly.I can see the data from the database but when I change information and save it it changes the entire column's information. My rows need to have different values in the same column so this is a problem.Here is my code so far, what the program does is makes a list of transactions that are entered.

Currently I have a problem with updating my database with values in my Data Grid View.
On my form I have a "Populate" button and "Submit Details" button.
The "Populate" button fills my Data Grid with numerous lines of data.
On the click event for "Submit Details" I want this data to be inserted into a table in my DataBase by looping through each record.
For Each dgi As DataGridView In DataGridView1.Rows
Dim productCode As String = DirectCast(dgi.FindControl("product"), Label).Text
Dim description As String = DirectCast(dgi.FindControl("description"), Label).Text
Dim quantity As String = DirectCast(dgi.FindControl("order_qty"), Label).Text

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. 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.

I 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]...

I'me getting real dumb with this one....I have this class:
Public Class whatever
Public id as string
Public name as string
public date as string
end class
Wich I use with this code:
dim personlist as new arraylist
dim person as new whatever
person.id="1"[code].....
and then i repeat so that i can fill my arraylist with all the information that I want to show in my gridview.The problem is this:
gridview1.datasource = personlist
gridview1.databind()
When executing, I get an error saying :
The data source for GridView with id 'gdpersonlist' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.

I need to display (read-only, I don't want the user to be able to modify the data) a set number of log entries. I figured using the data grid view would be the best solution. Basically the data is an error log that contains 3 fields (columns)
ID (a number from 1-20), Flag (number from 0-255), and a Description (string). I don't want the data linked to any database or anything.
These events occur asynchronously so I need to be able to add events (rows) to the data grid as they occur.
I also need the ability to clear all events (rows).
I guess the first question is if the data grid view is the best control in VB to use.
Is there a good example on using the data grid on how to add data to the data grid view one row at a time?
