Forms Data Controls :: Drop Down In Grid Header Doesn't Populate?
Apr 29, 2010
I tried adding a ddl into my grid header, it was origiinally out side and worked when i put it in the header it no longer worked, i am guesssing i have to do something other than cut past
It happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.
So far my edit page has a datagrid with the following code:
Basically I want to populate a drop down list with time slots for a user to select. If the time slot is already recorded in the database table I want to skip that one so it doesn't display as a selection in the drop down list.
So my drop down list looks like;
[Code]....
And then I have setup a datasource (even though I may get rid of it to bind in the code behind file)
I have a drop-down list that is wired up to a datasource from one table to retrieve a Vendor ID and Vendor Name. This ddl is outside a FormView that is wired up to a datasource containing Vendor contracts.
When I choose a Vendor from the ddl, I am able to populate a textbox outside of FormView with the Vendor ID from the ddl. However, what I need to do is populate a textbox within FormView with the Vendor ID. FormView is in Insert Mode by default since my page will be used for Adding Contracts only.
I have written a code that populates data from database into the tree using C# and is working perfectly , the thing is how can i populate the tree based on a selection from a drop down menu
