Grid Row Columns Fill on Button Submit

Question

User-159752495 posted

Hello,

          I have Gridview with Filled up rows from database along with drop down and button for each row. Each GridView Row has two columns that needs to be filled up only after button submit. First the drop down is to be selected, then button is to be pressed, then record is inserted into the database, and the corresponding row's 2 columns need to be filled from database. Button coding is done in rowCommand event . How do I use RowDatabound event in the rowcommand to fill up those 2 columns.

Thanks

Regards

    Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim x As String = String.Format("{0}", DataBinder.Eval(e.Row.DataItem, "fieldx"))
        End If
    End Sub

The sample using string.format to avoid null exception error

If you don't like it, use if condition to check eval("x") value is not null before converting
