I have an array in my code behind page. say:
int[] Hour = new int[24];
I also have a dropdownlist on my aspx page. say:
<asp:dropdownlist id="ddlHour" runat="server">
I want to bind the value of array to the dropdownlist such that when I dropdown the list, I get to see the values from 0 to 24.
How can i read multiple column values into an array list? I am trying to read a list of category names and category ids from database into an array list; i am then binding these values into drop-down list. With my current code, i am able to do with one column only but would like to pull both cat_name and cat_id so how can i do that?

<asp:DropDownList ID="DropDownList1" runat="server" DataTextField="ct_name" DataValueField="ct_id" AppendDataBoundItems="true">
<asp:ListItem Value="-1">Select</asp:ListItem>

I have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far:
[Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.
I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.
View 3 RepliesI have an array which contains around 50-200 hyperlinks. How can I pass this array to the client-side so that I can iterate through the array and display each hyperlinks as a list item?
The array will be stored in 'Application' as it's system wide and rarely changes. Could there be a more efficient way of achieving the hyperlinks as a list?
I am novice in .net. I am trying to display array length in a label. But it doesn't work out. I have given my code below.

I am saving one selected value of Dropdownlist to Database and If I am retriving that value I want that only that value should display in dropdownlist.
For e.g I have Dropdownlist asÂ
Monday
Tuesday
Wednesday
Thursday
If I select Tuesday and I saved it to database, On reftriving I want that Only Tuesday should be seen in Dropdownlist not the other listed value.
I have a problem with binding a DropDownList. Let's assume a database five years old with many historical records. In order to enable just working with active data every datasource has a column hidden which is occasionally set by administrator in order to clean up old records. The selection looks like
1) SELECT Id, Value FROM Table WHERE Hidden = 0
The issue arises when the user opens a form with old data. As some records in DropDownListhave have already been hidden an exception is raised as the component cannot find the data for the list. For this case the following selection is valid
2) SELECT Id, Value FROM Table
it is possible to combine these two selection queries? The display value should always use query 2 while the listed values should use the query 1.
Newbie here, I'm trying to setup a webpage using the following tutorial posted on this website:http://www.asp.net/(S(pdfrohu0ajmwt445fanvj2r3))/learn/data-access/tutorial-07-cs.aspxThe problem is when i try to add the fields on 2 columns on my table and then populate a dropdown list with the concatenated columnie. my table has the columns ID and Name. I want to display it as:"ID - Name" in my dropdownlist in stead of just Name. eg: "AB - Treatment Centre"I've been googling and so far the only solution i've come across is to generate a TableAdapter with the following query:

Singles and suppers are money fields for the price of same item. A bit like the price of a Small, Medium or Large item. What I would like to do is display the 'Singles' price and 'Suppers' price in seperate listitems so the user can choose 1 of them.
