I have a MySQL database, and I'm currently creating an ASP.NET website to update data in it. I'm currently having trouble changing the data with GridView.

I have made an ASP.NET page with a ListView which binds to a Linq datasource which have inserting, updating and deleting enabled. All very trivial and well designed by MS. It all works very well so far.
Now I add a DropDown control to the page and binds the Linq datasource Where clause to the dropdown using the following code:
[Code]....
Now I can filter the listview based on the DropDown control. It works very well and I can still insert and delete rows in the ListView.
PROBLEM:
However when the DropDown control is used to filter the ListView rows I can no longer use the Editing functionality of the ListView. The row never goes into editing mode when the Edit button is clicked.
When the DropDown is not used for filtering - is in default state - editing works as expected.

I ahve displayed a group of data in my gridvew with the edit option linkbutton template field for each row. The gridview columns consist of employee name and projectname and total hours field employee worked.
So in this when i click the edit button using the datakeynames alue for project name id and employee id ,i have to redirect the page to another page with the values in the grid for the particular employee.so that i can update the totalhours field in the redirected page.and if i press the update button in that page then the page should be redirected to the gridview page with the updated value for the particular employee and project. The page which should be redirected consist of project name dropdownlist, module field,date field and total hours field. No employee name field.
Using the gridview rowdatabound field i have postbacked the url page with the project name id but it does not displays the project in the redirected page.And employee name i have to redirect with the session value i think?
