I have a gridview with two columns (item templates) one is a dropdown and the other is a textbox. I need to select an item from the dropdown (which I can do) and then get the cost of it and then put the cost in the texbox item template of the gridview.

I have packed the access 2007 project management database and moved it to SQL Server. I'm aware that SQL doesn't populate dropdown lists for the Status and completion Percentage columns.

Using C# and sql server. I have a gridview which is populated using a sql query. I have 5 columns in the gridview ( projectid,project name,description,date,status).

I want to have a drop down list for status instead of a text box with values Started,Inprocess,Complete, Inhold.
I have a dropdown list within a details view that allows me to set 1 or many categories to a perticular record(in this case a photo). The select command in this case only displays those catetegories that are not already attached to the selected photo.
all works well and as you select a category and add it to the database the category is removed from the dropdown list and is added to a gridview which shows all categories that photo is stored with.
My Problem is that when i delete the category from the gridview the dropdown list does not delete with said deleted item unless i do a "click in URL bar and press enter" to totally refresh the page.....
how to refresh the dropdown list in the details view after the gridview item has been deleted?
I have a problem where I have 4 dropdown lists which are populated from 1 drop down list depending on its value. The problem I have is that when the form is in edit mode the value for dropdown 1 is visible but when I click on dropdown 2 (or others) they appear to be unfiltered. However if I change the value in dropdown list 1 it will then filter dropdown 2 correctly. Am I missing something perhaps in the form load event. My code is currently in dropdown 1's selectedindexchanged and formview_databound if formview is in edit mode. Autopostback is true for all dropdown lists.
I have a DetailsView that binds a User's Profile data into an ItemTemplate upon the Page_Load. When the user chooses Edit Mode, all of the Data is correctly carried over, except for the DropDownLists selected values. If on the ReadOnly page, the user's data shows "Male" for the Sex, then on the edit Mode page, I would like the DropDownList that gets the sexes from the database ("male", "female"), to have automatically selected "Male" in the DropDownList, not the lowest indexed item.
In web config file I have add key values specified.
In the formview I have labels on edit , item and insert mode that I want to display all the time by getting those values from web config. I'm able to do that with no problem but when I change the modes between edit to insert or item view, I lose those label values until I hit the "select" twice from the Gridview, those values re-appear. Below is the snippet of the code. What do I need to do to retain the category values all the time?
I have a "report" the users can run it basically creates a simple gridview. In the gridview the user can click on a claim ID.

I want to use the claim id passed in the url to locate the listview row to open in edit mode, so the user can make changes / alterations to the claim.
