Hello everyone!
I've got a problem in ASP.NET 2.0. I am trying to code an event which will add a user to a defined role in Sql Database. The event is raised when a button is clicked. Actually there are two dropdownlists, dropdownlist1 and dropdownlist2. The user first selects a UserName from dropdownlist1 and then selects a role from dropdownlist2. When a button is clicked, the UserName selected from dropdownlist1 will be added to the role selected from dropdownlist2.
In the .aspx.vb file, I have declared the UserName, RoleName As string as follows:
Dim UserName, RoleName As String
and then I have written the following block of codes in the button_click event section:
Roles.AddUsersToRole(DropDownList1.SelectedValue, DropDownList2.SelectedValue)
SqlDataSource1.DataBind()
SqlDataSource2.DataBind()
DropDownList1.DataBind()
DropDownList2.DataBind()
where SqlDataSource1 is the datasource used for dropdownlist1 and SqlDataSource2 is the datasource used for dropdownlist2.
Now when debugging I'm getting the following error:
Value of type string cannot be converted to "1-dimensional array of string.
Could anyone please help me and tell me if my code is correct or explain to me how to code this event correctly?
Thank you
