Forms Data Controls :: Obtain A Column From A Gridview And Use It In Calculations?
Jun 3, 2010
I have a gridview with the following columns: months, number of injury, expenses. my month column is a string, my number of injury column is a number and my expenses column is a number. I need to first obtain the month column as an integer and then obtain the number of injury column in my gridview. Once these columns are obtained, I want to be able to get the total number of injuries. How do I solve the problem. First obtain the month column and change it to an interger or gridview
Next obtain the injury column and then add each row in the injury column to get the total number of injuries.

First of all, when using the GridView control with Delete enabled, when I delete a record is the event handler in the code behind file handled before the record is deleted or after? I need to obtain a counter value that I have set up in the record before it is deleted so that I can decrement all of the counter values that followed it. Is the best way to do this to open a connection in the Delete even handler and take care of it by code, or is there another way to access a column value from the GridView control that would simplify the process?

In a details or form view I have a number of entries from a database
For example:
Pass-Attempts, Passes-Completed, AvgYds, TdPercentage
If I want to perform a simple calculation on these values, and then display them in the same details/form view
Such as:
QBRating =((Passes-Completed/Pass-Attempts)*100)+(AvgYds*5)+(TDPercentage*4)
With the ideal result being:
Pass-Attempts, Passes-Completed, AvgYds, TdPercentage, QBRating on the same Details/Form view.
So basically I need to programmatically get at those values, perform calculations on them and them display them back in the same control.

I have a FormView Bound to an SQL data source. In the DATA there are 2 columns that i would like to multiply together and display there rate
<asp:TextBox ID="txtPeople" runat="server" Text='<%# Bind("People") %>'></asp:TextBox><asp:TextBox ID="txtRate" runat="server" Text='<%# Bind("Rate") %>'></asp:TextBox><asp:TextBox ID="txtTotal" runat="server" Text='<%# Bind("Rate * People") %>'></asp:TextBox>
This is just an example above but i believe it shows what i am trying to do, there is no calculated column in the database so i can not bind to that directly, and i can not just add the column to the data as its not in my permissions. So how do "Bind" the value of two columns multiplied together to a third text box?

I use this code to obtain a selected data from GridView control. I created a user control and reference it to ASPX page. However, for some reason I can not access public methods IndexChanged to retrieve information of selected line.
*
User controls:
*
Public gridRow As GridViewRow
Public Event IndexChanged As GridViewSelectEventHandler
*
Protected Sub GridView_SelectedIndexChanged (sender As Object, e As EventArgs) Handles gv.SelectedIndexChanged
******* gridRow = Grid.SelectedRow
******* RaiseEvent IndexChanged (sender, e)
End Sub
*
ASPX page:
*
*
grid.IndexChanged - there is no such event in the selection (the grid is the name of the user control)

I have a table that includes a state column and a price column.
I am able to obtain the average price from a particular state using:
SELECT avg(Price)
FROM MainTable
WHERE StateId=x
I would like to display the average price from each state. The only way I know of doing this is 50 seperate datasource controls. Is there another way?

I'm facing a wierd problem with GridView and ObjectDataSource. I bind GridView to my business objects via ObjectDataSource. Everything was working fine until I decided to add a new field in my buisness object and wanted to add a column to GridView to show it. Somehow that column is NOT shown in the GridView's list of available columns. I have tried refreshing schema, rebinding, etc. I'm using GridView inside a user control which is used as a web part. Does that make a difference ?
