Web Forms :: Passing Values From Databound DropDownList To TextBox
Mar 9, 2010Let's say I have DropDownList ddlRooms bound to the datasource which returns list of available rooms from table tblRooms. On the other hand I have users, and their info is stored in table tblUsers. Using FormView frmUsers can be inserted, edited and updated... frmUsers is be bound to separate datasource. To each user, I would ilke to assign a room, so the value of txtUserRoom will be populated based on the selected value from ddlRooms. How can i pass the selected value of ddlRooms to txtUserRoom while keeping txtUserRoom stil bound to user datasource? Do I need two separate fileds or can i just put value of ddlRooms into datasource user?

then,
if a user unchecks some item and clicks the save button. then the selectedindexchanged will fire and i will do some logic.

Forms Data Controls :: Change The Values In Dropdownlist In Gridview?
Aug 4, 2010I got a gridview -CompGrid, having 3 columns - Dept, Employees, Status.
The 'Status' tab need to be edited. So that I put a Dropdownlist as an Itemtemplate and connected the 'DataValueField' as 'Status'.
Now I can edit each row by row only. Some times it needs to update all the employees status in one department.
So that I placed 2 more dropdownlists in outside of gridview.
1. Department List, 2. Status List.
My requirement is this, When I select one department and corresponding status, it should update all the records of that department in the grid.
