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?

I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
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 am using GridView ,I want to do a validation like if i edit any one of the Cell in that column, it will through the validation when the sum of column value is more than 100. How can i do this validation?
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 want to use a Datalist to list products from sqldatasource. When i select the Product i would like to retrieve the associate Product value in the code behind page so that i may use it to display data in Grid.

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 ?
