DetailsView template field problem

[Ram]

I'm using detailsview control with a template field which contains a
dropdownlist
I databind the dropdownlist during page load, now the problem is
dropdownlist loses state during postbacks, i looked at the enableviewstate
property to see if viewstate is enabled and it is.

Any ideas!!!

Thanks,

It depends on which control/event caused the postback. If you have the
dropdownlist within an EditItemTemplate then you can get its value during the
processing of the ItemUpdated that is triggered by the DetailsView like this:

void DetailsView1_ItemUpdated(object sender, DetailsViewUpdatedEventArgs e)
{
DropDownList ddl =
(DropDownList)((System.Web.UI.WebControls.DetailsV iew)sender).FindControl("DropDownList1");
if (ddl != null) //you found the dropdownlist
{
//add your code here
}
}

Hi Ram,

You should add a check in your page load method for a postback:

if(!IsPostBack)
{
//Bind your data
}

If you don't do this, your ViewState will be reïnitialized during
every page load.

Also make sure that you have unique values in your dropdownlist or it
will return false data from the viewstate.
