I am using VB 2010 with an Access 2010 database. The Access table is the data source for a DataGridView created by dragging the table from the DataSet onto the form. The table has 3 columns - First, Last and DOB (Date of Birth). I want to have a column in each row to show the person's age. I added an unbound cell in the DataGridView called Age, but cannot figure out how to fill the cell with the information I need. I tried using the DataName property, but that will only allow me to enter columns already in the grid. I think what I need to do is fill this cell (Age) by a value computed from DateDiff(DateInterval.Year, DOB, Now), but I cannot figure out how to do so.

I have a button on the page and a gridview with checkboxes on the first column. The gridview is bound to a List. On buttonClick, I need to retrieve the underlying bound data item (MyEntity) for each selected row. How can I do this? I can't simply recreate MyEntity based on the gridview columns, because I am not displaying all the fields of MyEntity. I need a way to get a hold of MyEntity based on the key (MyEntityId).

View 2 RepliesI could really use some help on this. I have been searching for a solution on the web but haven't been able to find much help.I need to add textboxes to a gridview edit cell, based on the number of rows of text in one of the cells. I have coded the capture of the number of textboxes I need to add.
But I am not sure which Gridview event to add the code, when going into edit mode, to run the loop that will insert additional Textboxes in a specific column of the row selected to edit.
The user sees colA that has text with line vbCRLF's embedded say:
"This is sample text."
"Line2"
"Line3"
My code reads three Carriage Return, Line feeds. So when the user goes into Edit mode I want to provide one text box for each line or more accurately, add two more as one will already exist.
In C# when I programmatically need to get a specific control from a GridView, I insert in my RowDataBound event handler:

Dim hl = CType(e.Row.Cells(n).Controls(0), HyperLink)
and
Dim hl as HyperLink = CType(e.Row.Cells(n).Controls(0), HyperLink)
