Can not add to/modify dropdown list after datasource has been load

[Guest]

Hi,

In my dropdown I bind to a datasource. After that I try to do one of the
following:
1. Add an Item to the dropdown using dd.Items.Add(newe ListItem("textstr"));
2. Change the text of an existing item in the dropdown. For this one I use
the
followingubDD.Items[pubDD.Items.IndexOf(pubDD.Items.FindByText("textstr"))].Text=otherText;

Neither one works.

Thanks for any suggestions....

After databinding try dd.Items.Insert(...)

Thanks but it didn't work:
pubDD.Items.Insert(recCnt,new ListItem( "WINK", recCnt.ToString())); For
the new insert
That's for inserting a new one.

Modifying an existing one didn't work either.

After databinding try dd.Items.Insert(...)

You don't have to use databinding.
You can iterate through the datasource and add each item to the dropdownlist
with a few lines of code.
Then you can add anything you want without such hassles.

Set appendDataBoundItems

Do as above but set the property 'appenDataBoundItems' on the dropdownlist,
this merge the data from the database with your static bound item.
