It is a general ASP.NET questions. Many times some items in dropdownlist will become inactive (retired)or active again. It is easy to handle in the new records which use only currently active items. But how to handle the inactive items which need to be used to show history records. It bothered me a long time, not sure how to solve this problem efficiently.
View 7 RepliesI would like to know how to display active and inactive staff members in my datagrid. I would like to be able to have a default setting of the active members with a button or hyperlink saying "display inactive members" and when you click on "display active members" it will show the inactive members with the link saying "active members". There is a column in the Staff table called is_active with 1 or 0 in it.
Here is the aspx code:

I have a tabcontainer with three tabpanel. The first tab is always enabled, while the other two get enabled and disabled in the code-behind depending on some conditions.I would like to customize the header style of the second and third tab such that: - If the tabs are disabled, the header (title of the tab) font color should be gray - If the tabs are disabled, the header (title of the tab) font color should be blue. Currently, I have the following in my style sheet: `a.ajax__tab_tab{ color: blue; }`but this always sets the tab title font color to blue, regardless of whether the tab is enabled or disabled. This piece of code shows the conditions to enable or disable the tabs. Can I control for style here as well?

this is my first post as you will easily see i'm quite new to this and am struggling. i have some working code that pulls user information from our active directory. the only way i've seen so far to display these results is to place it in a "For Each" statement.this can then be output to the page. however if there are lots of results this can take a while, so i was wondering if it was possible to be able to step through and handle the results by an index? here is what i have done so far:

the other issue i have is that i wish to be able to change the search criteria to the "Path" and then go to an idividual when clicked on.i have checked that this would work but cannot get my head around how i would make the result "Clickable" As you can see i have also tried using list boxes but was unable to format the results sufficiently.

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 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.
