javascript

The below logic is for javascript only.

In the dropdown_selectionchangedEvent()
{
 //Fetch all the dropdowlist controls from the datagrid. use document.getElementsByTagName()
// get the value from the dropdownlist controls
// Sum-up the values.
//Find the footer control in the gridview control and bind the value there.
}

I don't have visual studio to create the complete set. Let me try with Notepad and IE browser for the javascript part.

Here is the logic,

During the databound event, add the javascript for the dropdownlist selectionchanged event.

In the comobox_selectionchangedEvent()
{
 //Fetch all the dropdowlist controls from the datagrid. use document.getElementsByTagName()
// get the value from the dropdownlist controls
// Sum-up the values.
//Find the footer control in the gridview control and bind the value there.
}

Please let me know, if you need more help.

Should be possible. 
Can you please upload screenshot of your gridview (while running)?

I also suspect on this line of code in JavaScript block:
-----------------------------------------------------------
var grid = document.getElementById('<%= Gridview1.ClientID %>');
-----------------------------------------------------------

should be:
-----------------------------------------------------------
var grid = document.getElementById('<%= GridAssessment.ClientID %>');
-----------------------------------------------------------
as per your code.

In order to show the total in footer you need to sum the total on RowDataBound and assign it to the label control in footer. Refer to this post:

It will help you achieve this purpose.


Hope it helps :)

It looks like, the gridview name is wrong in your javascript.
In your HTML , the gridview id is GridAssessment and in your javascript the control name is 
GridView1.ClientId. 

Change your javascript as below,
var grid = document.getElementById('<%= GridAssessment .ClientID %>');

Please let me know, if it is not working.
