Web Forms :: Change Items In DropDownList In Code Behind?
Dec 3, 2010
I have two DropDownLists; DropDownListStart displays the hours 09:00 - 19:00 and DropDownListStop displays 10:00 - 20:00. When the user chooses one of the hours in DropDownListStart I want the program to adjust what's shown in DropDownListStop so that the first hour shown is one hour after the hour chosen in DropDownListStart. How can I do that in code behind (c#)? An example: if the user choses 13:00 in DropDownListStart I want DropDownListStop to display only 14:00, 15:00, 16:00, 17:00, 18:00, 19:00, 20:00.

I removed some items from a dropdownlist, and now I want to re-initialze the items which I have on aspx file.
<asp:DropDownList ID="s1" runat="server">
<asp:ListItem Value="0.00">Select</asp:ListItem>
<asp:ListItem Value="0.25">0.25</asp:ListItem>
<asp:ListItem Value="0.50">0.50</asp:ListItem>
<asp:ListItem Value="0.75">0.75</asp:ListItem>
<asp:ListItem Value="1.00">1.00</asp:ListItem>
<asp:ListItem Value="1.25">1.25</asp:ListItem>
<asp:ListItem Value="1.50">1.50</asp:ListItem>
<asp:ListItem Value="1.75">1.75</asp:ListItem>
</asp:DropDownList>
Such as I removed "1.50" and "1.75", and when a button clicked, the dropdownlist will initialze again with these 8 items. How do I do that?

I have a series of dropdownlists on webform in ASP 4.0. The first drop down is filled upon load, and then when a user selects a value from that list, it populates the second dropdown. To accomplish this, I have a SQLdatasource with a parametersource of the first drop-down list control. This works great, except when a user changes their selection from the first drop down. It performs the query, but then adds the list of items to the ones that were already there from the previous selection, instead of replacing it with the new data. Here is the code:
[Code]....
Do I need to do something on selectedindexchanged to somehow "clear out" the previous datasource? I can't find anything about this online, although one person seemed to suggest it was related to using a master page. (which I am using).

-DE
-AU
I need to heading "Europe" to be not selectable? the database has a column (selectable = 0) for those heading and I need to make them not selectable on the client side.

I see that dropdownlist has an "items" property to get the list of displayed items for a dropdown, but it doesn't seem to have an equivalent property for getting the "values" associated with the items. For example, I may have a dropdown that displays "High", "Medium" and "Low", but returns values of "H", "M", "L". How can I easily get that list of HML?
