DropDownList selected value in a datalist

[Chris Kettenbach]

Good morning all,
I am sure this has been asked but I did not see anything.
I have a datalist control. In the edititemtemplate I have a dropdownlist.
I know on the itemdatabound event is where I can set the dropdownlist
selectedindex. How do I set the correct value?

private void lstDegrees_ItemDataBound(object sender, DataListItemEventArgs
e)

{
DataList dl = (DataList)sender;
if(e.Item.ItemType == ListItemType.EditItem)
{
DropDownList ddl = (DropDownList)e.Item.FindControl("ddlState");
ddl.DataSource = GetStatesLookup();
ddl.DataTextField = "Abbreviation";
ddl.DataValueField = "StateID";
ddl.DataBind();
ddl.SelectedIndex = ddl.Items.IndexOf(ddl.Items.FindByText("AL"));
//how do I get what the correct value from the datalist datasource? The
field is StateID
}

}



Any suggestions? Thanks to everyone who responds.

Regards,

Chris

After setting the SelectedIndex property, SelectedValue should get you the
value (in this case, StateID) for the selected item.

Chris,

It's easier than that.

ddl.SelectedValue = "AL"

SelectedValue gets the value of the item in the list control or selects the
item in the list control that contains the selected value.

I am sorry. "AL" is just an example. I want the dropdownlist selected
value to be what the of the StateID was in the datalist datasource. Is
there a way to do that?

In vb.net you use

ddl.SelectedIndex =
ddl.Items.IndexOf(ddl.Items.FindByText(sender.datasource("StateID")))

how do I accomplish this in C#?

Chris,

It's the same thing. Get the name of the selection from the list and use:

string Selection;
Selection = [Selection from datasource here];

ddl.SelectedValue(Selection);
