View 1 RepliesI have a dropdownlist which get item from database (say this field has 10 records for this dropdown list.
I want the users are not restricted to these 10 items. What is the quickest way to do so the user can type in new values and insert into database ?
I would like to highlight (bold) and disable certain items in the dropdownlist for selection.
My dropdownlist is fed from a SQL table of countries e.g.
Europe
-UK
-FR
-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?
View 5 RepliesI 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.
