Forms Data Controls :: Change Values / Dropdowns Without Rebinding Old Data And Updating Visibility Of Panels Based On Predefined Rules

Aug 26, 2010

I am working with a formview edititemtemplate. Currently in my page load, i have some stuff that would show or hide certain panels based on dropdownlist values. These dropdown values get binded during page load. I need to be able to change the values/dropdowns, without rebinding the old data, and updating the visibility of the panels based on predefined rules.

I have experimented with putting my formview.databind() in page load if isnotpostback, in prerender, in prerender if isnotpostback. I have tried my rules (ex if ddlState.selectedvalue = "DE" then pnlDelaware.visible = "true") in the page load, and the page render. I'm just not sure how to get the stars aligned here. The closest i have come is having the databind in the pageload if notispostback, and the rules in the prerender. However I get an error "dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items.

Forms Data Controls :: When Updating Gridview When Hide Columns Values Turn To Null?

Mar 5, 2010

I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?

Forms Data Controls :: Updating Encrypted Data To SQLServer Database With GridView

May 31, 2010

I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.
