Default value for Dropdownlist that get's it's value from Database.

Hi,

I am using an Object Data Souce to retrieve the value of a Dropdownlist from a table on MS SQL server 2005. I want to make a default value appear on the Dropdownlist intially, should i enter the default value into the database table or is that a better way of doing it?

Any suggestions will be very much appreciated.

Better way:

<asp:DropDownList runat="server" ID='ddl1' AppendDataBoundItems='true' DatasourceID=...>

<asp:ListItem Text='default' Value='default' Selected="True"></asp:ListItem>

</asp:DropDownList>

Hi Heartattack,

i wrote code similar to yours, but i now get this error message:

Incorrect syntax near the keyword 'Default'.

This is my version of the code:

<asp:DropDownList ID="AgeDropDownList" runat="server" DataSourceID="AgeObjectDataSource"

DataTextField="Age" DataValueField="AgeID" AppendDataBoundItems='true'>

<asp:ListItem Text='Default' Value='Default' Selected="True"></asp:ListItem>

</asp:DropDownList>

i think the error message suggests default is a reserved word.  try to change default to some other word.

Code's working for me. Note, however, that on insert or edit or databinding, you must make sure that the selected value of the drop down is not the default OR the default is an acceptable value in the database column.

HeartAttack : you should use a Double Quotation around the Attribute values !

<asp:DropDownList runat="server" ID="ddl1" AppendDataBoundItems="true" DatasourceID=...>

<asp:ListItem Text=" Please Select  Item "  Value="" Selected="True"></asp:ListItem>

</asp:DropDownList>

Mozilla get's no style tag's from .net server.
I made a webform in web matrix, and it looks fine in IE. If I open the same link whit Mozilla, it looks like a disaster. When I look at the HTML source, there are no style tags as in IE. But when I save the HTML source from IE (the one whit style tags) and open it in Mozilla, it looks perfect. So the onley reason the webform looks wrong in Mozilla, is because the .net server detects Mozilla and not IE and sends a style less HTML source. Wy? Mozilla does support style tags. Is there a solution for this bug? Or is this a uh.. feature? ..Mivz Update, I have got some more info. It is ...
