Web Forms :: Dropdownlist - To Read The Time From The Database?
Jan 24, 2011
I have 3 drop down list. 1 is for hours; 1 is for minute; 1 is for AM or PM. I want to read the time in from the database and set the drop down list for the users so they can make updates if need be. I tried ddhour.selectedindex = 1. Can I do this in asp??
Using: Visual web developer 2008; APS.net; VB.net Code; Access db
I several instances of a webcontrol on my page. The codefile can't see the drop down list's Text property so I am using the FindControl. I have had this working, but only if I specify which 'instance' of the webcontrol I want to read. Due to the fact the webcontrol is repeated 6 times on the page, I want to put this through the loop. This is the working version:
[Code]....
Now, I have tried to loop through all web controls. My code (C#)
[Code]....
The value of ddl.Text and ddl.SelectedIndex is always null.
I have a survey form, survey.aspx, that looks for information about 3 different people (hiking guides) who are all contained in a single DropDownList. Instead of repeating the list over and over, I figured I'd put them all into a single user control, GuideList.ascx, shown here.
[Code]....
The form has 3 instances of this User Control. Here’s what the first one looks like:
[Code]....
In trying to access the value the user chooses from the DropDownList, I have created the following code in GuideList.ascx.cs
[Code]....
In Survey.aspx.vb, I have the following, that often blows up because it doesn’t like G1:
[Code]....
I have tried using GuideList1 and GetGuide and GuideList1.GetGuide and GuideList1.G1 and all sorts of variations, but cannot seem to figure out what I'm missing to access the value of the DropDownList.

I'm populating my dropdownlist control with data that is stored in database which is in time format.Data, after being populated into dropdownlist, looks like 13:09:49.5577199.I want to convert this into something like this - 01:09 PM.To convert date format in dropdownlist, we do it with dataTextFormatString="{0:dd MMMM}". But for converting time format, how to go about?
I have a lot of requests that read my Web Config file (eg. variable = WebConfigurationManager.AppSettings["BLAH"]). I am wondering... Do WebConfigurationManager.AppSettings read from disk each time, or is it cached in memory. If it's read from disk each time then I guess I will need to move the variable to a static variable so as to improve my app performance...
I have to set dropdownlost to read only. I can set enabled =false. But I cannot set font color to regular dropdown text. It will show like blur. The samething I did textbox.readonly=false. There we can see font same as regular text, no change. The same way I want read only for dropdownlist. Is there any way we can do with CSS or javascript or jQuery ?.

I just purchased a premium Windows hosting account from 1&1. I wish to host my site on there. I have been working on it for quite some time.
The most important part of my website is Authentication, and I cannot get my database to work.
I need to get my site to be able to connect to E:BlahBlahBlahApp_DataASPNETDB.mdf. It is SQL Server 2005. And yes, my hosting package supports it. I have a database set up. Would I need to configure my database to read the .mdf? Or is there a special connection string for files.

Given a Database that has a table Called [Bid Transactions], which contains records of all available auctions that are currently running on an ASP.net website .. something similar to Ebay.com, when the deadline of the auction passed, I should close that auction, Send a notification message to both the item owner and the bidding winner to inform them.
how should I keep track of all open auctions? how could I monitor all their ending time and update the Auction status to be "Closed" on Real-time basis? ..
(1) Using SQL jobs ? .. that should reduce system performance .. shouldn't it ?
(2) A back-end service that is running on the server and uses Threading ? .. I have no clear background about that solution.
