When someone selects one of the search criteria, I want the other dropdownlist boxes to re-populate with only the information from the current search and take out all other information if that makes sense. This search functionality works except it the dropdownlist boxes stay populated with all information originally loaded from the database. Here is my code:

View 3 RepliesI am trying to populate a gridview when you select the dropdownlist.selected value. I don't want to use the sqldatasource or any other datasource. I am trying my best to achieve this, but didn't succeed till now. One of my friend said that i need to get the selected value from dropdownlist and search for the data in the database using the selectedvalue and populate the dataset and bind to the gridview.

I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!
Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.
I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?

This works fin on a DropDownList that is not in a FormView, so I know its not the Code. and the record I am updating is 2010, so the record is not out of range
I thought this one would be easy, but no go. What I am trying to do is the following: I have two DropDownLists in my InsertItemTemplate, each bound to its own datasource. After the fields in this form have been filled out and the ItemInserting event fires, I rebind the ListView to its datasource, but the DropDownLists turn out empty. I tried to bind them in the ItemInserting event and it seems they get filled, but nothing shows up in them when the page loads. I also tried to fill them in the ItemDataBound event, but the e.Item.ItemType == InsertItem doesn't do it.
How can I fill those DropDownLists?

I have a Gridview which I'm populating through code behind. A couple of columns of the gridview I've set up to be drop down lists. What I want, is that when I run my Insert query, it takes the drop down list selected value, finds the appropriate ID and uses that ID as part of the insert query.
Below is my select and insert query.

Does any one know why it does this?

I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview. For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I'm trying to programatically populate some dropdownlists inside a formview in EDIT mode, like this below.
[Code]....
I orginally had this running as part of the pagelaod event, but I'm thinking that b/c the page loads first, it doesn't populate the fields in EDIT mode until after the data is saved, and then page is reloaded. Now it knows it's in "Edit" mode. Am I thinking clearly here? Not sure if this is the order of things. So I thought I should just use a formview_modechanged (or similar event) so when the user switches modes, it populates the fields - but I'm not sure which event I should use. I've tried "Modechanging", "modechanged", "prerender", etc, but with no luck. Here's my new code... not sure what's up? Is it simply I've got the wrong formview event? Or am i missing something? Is there an easier/better way to accomplish this?

I have no problem when paging my FormView, the dropdownlist does not read the next record and keep the value of the first loaded record? All other textbox control behave normally and move from record to record excepted the ddl??Here the code.

Dim myCommand As SqlCommand = New SqlCommand("SelectSupplier", myConn)
