I have 3 buttons that change the Information being displayed in my Gridview (Previous, Today, Forward). Now management wants to SUM the Date's information by column, I have figured out how to do this by changing the BoundField to a TemplateField and then add a FooterTemplate with a SQL DataSource. When I Press either the Previous or Forward button the data does not change in my Sum'd Footer column.

I having problem to show footer template at data grid when there is an empty data. I need to show the footer template in order to let user input new record.
I have used the above grid view in my application ... Its working good, no problem.
Upon clicking the Addnewrowbutton, it uses to create a new row dynamically.
What i need is, new row should also be created dynamically, upon pressing enter key in the last textbox on a particular gird view row. User always can't go and click addnewrowbutton every time to create new row. Instead of it, user can press enter in the last textbox on a particular grid view row to create new row.
I am using a Gridview to Edit, Delete, and Insert (thru the footer). I am tryng to usr required field validationg a column called qty .When I insert a record through footer validating is working fine.(Add button in footer template)
But when I edit a record and it is validating both footertemplate and edititemtemplate.
I have created a gridview dynamically from scratch and added it to my aspx page. This works fine, but i have a button in the footer of on of the columns, which when clicked on makes the gridview disappear and doesn't fire the onclick event that it should. This should obviously not be the case. My question is why does the event not fire and why does the gridview vanish? Bear in mind i have never created aa gridview in the code behind before, so excuse me if i am being dense

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
