Asp.net - Update Database Based On Gridview Value?
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
[Code]....
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 tried an update however you cannot use an aggregate in an update as I have found.

I am populating a datagridview not with a datatable but with a list of instances of a class I created. The data for the instances is read from a database.
Looks like this:
Public Function GetSecurities() As System.Collections.Generic.List(Of Security)
Dim com As New SqlCommand
Dim rdr As SqlDataReader

I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page:
<asp:SqlDataSource ID="msgUnread" runat="server"
ConnectionString="<%$ ConnectionStrings:edinsec %>"
[code]....
As you can see I was playing with WithEvents but that didn't seem to help. In the above code all I was trying to get was some kind of reaction to the clicking of a checkbox - but nothing happens (no errors, either).

I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

My gridview does not use controls, because it is populated using expressions
<asp:TemplateField HeaderText="As Of Sales">
<ItemTemplate>
<%#Getsales(Decimal.Parse(Eval("asofsales").ToString())).ToString("C0")%>
</ItemTemplate>
<FooterTemplate>
<%#Getsales1().ToString("C0")%>

I have a GridView with a button located beneath it. The GridView's height is set dynamically. When the height is set, it displays on top of the button. What I want to do is move the button down so it still displays just below the GridView when its height is changed.I know I can just set the location of the button, based on the height of the GridView, but is there a way to link the height to the location of the button? Like anchoring the button to the bottom edge of the GridView.

I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview. I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows). If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that.

I have a list of items in a GridView, with one column I'd like editable through a DropDownList.
I do not wish to put the GridView into 'edit' mode or have any 'confirm/update/save' buttons.. I just want autopostback on the DDL, and an OnSelectedIndexChangedevent to update the row.
Problem is, from my OnSelectedIndexChangedevent within the DDL, although I can see the new value to save, I can't discover the row to update from the GridView.
how I can achieve what I wish? Other than perhaps storing the row id within the DDL? Maybe turn it around so the GridView's events are called?

Im learning to use a gridview and a problem that im seeing is that putting an edit command in the gridview so that I can update a particular row. When I click the edit, it turns to the update as expected, I hit the update and the particular field turns the row into editable textboxes which is expected. The problem that I notice is that if I click another row, I get this error:

I am trying to get a parameter for my update from the gridview but it is an ID column that I do not want displayed. If I display the data in a boundfield it works fine but if I set the visibility to false the parameter is no longer sent to the update stored procedure. There does not appear to be a hiddenfield column that I can put into the gridview.I have tried to set the parameters through the code behind but I am not certain on how to access the data I want the following code does not work (It sets the parameter to nothing

I have asked a question similar to this in the past. I was able to resolve it by removing gvRowDataBound completely from the code. This is similar code except I can't remove gvRowDataBound sub.
The issue is that when you click the Edit button of the first row, it allows you to successfully update that row.After the first row, if you click on thr edit button of any other row, enter the value to update, it doesn't update that row.
Instead, the cursor moves down to the next row. I didn't design this and having difficulty figuring out what needs to change.
