Is there a way to display several records in the datatextfield in a asp dropdownlist?

I know the fix when populating the dropdownlist from a datagrid was to edit your SQL query but the values I am receiving are sent via an XML string.


The idea would be to display a name, price, and date in the dropdown text.

Hi there..

This problem is stopping me from winding up my project. I have a webform where there is a pop-up page that populates one text box and 2 dropdowns. And I also have a checkbox list that does a postback. Whenever the checkboxlist does a postback, one of the dropdownlist's value is reset. It happens with only one dropdown list.

Hi,
As we know IE SELECTdrop down list has limitations on tool tip on individual option items and also horizontal scroll bar.

Hi,

For the page I'm developing I need a DropDownList with CheckBoxes on it, so that the users can choose more than one option without having to use the Ctrl key (and it's more intuitive). Because my options are being retrieved from the Database, the list of option can be really big, so using a CheckBoxList would use a lot of space.
Please, can anyone help me with this? I'm almost desperate! I have been search for a couples day,...

Hi all. I need help about this particular aspect.

In a webform I have an <asp:textbox> (txtName) and <asp:DropDownLi st> (lstSchool) with 2 values inside.

I have typed in a value for the textbox. When I select an option from the dropdownlist, I would like that value(String) to be concatenated with the textbox's value. How do I achieve this in JavaScript?
