I'm developing an E-Commerce, website and within my CART webform a have one Quantity texbox for each product. When a customer insert a number inside of it and click on a update Button, it fires a function and the Product Quantity is updated. It is currently working fine.
But I want to fires the same function and update the quantity without the click button event. When the MOUSE OUT the TextBox, I want to update the quantity automatically.Is there any way to do that?

I was wondering if setting a default value for a SelectList is considered to be presentation logic or business logic? For example, if a requirement is that an Employee cannot be saved without a Location, but 99% of the time the location that would be selected is a particular item -- say Atlanta. Because of this, the location SelectList should be defaulted to Atlanta when ever a entry screen for a new employee is displayed. Should I be defaulting the location in the model or in the view-model? One thing I realized is that the unit tests become awkward because in both cases, I'd be forced to test against a location that will always be present in production but I cannot create a unit test with my own test dataunless "Atlanta" was in the set of locations being used in the test.

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?

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 have a DropDownList with a list of orders. When an order is selected from the list I generate a GridView with details of that order. Within the GridView I call other databound controls and all works fine until I finish the orders in the DropDownList
I have tried to enclose the code within a if dropdownlist.items isnot nothing end if but it makes no difference
This is the code:
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
If DropDownList1.Items IsNot Nothing Then
GridView1.SelectedIndex = 0 [code]...

I am using C# ASP .NET 2.0. I have a web form with two DropDownList controls. In my code behind I get data from a DataSet. One column is a string (Month), and another is an integer (StatusID). I am setting the selected item in the each DDL in the code behind by doing this:
[Code]....
I have a button with a Click event. What I want to do in the click event is be able to check if the currently selected item in each DDL (if the end-user changed the selection) is different from what was selected in the above code.
