aspx_professional thread: DataList Question


Message #1 by "Rich K" <rich@r...> on Mon, 23 Sep 2002 11:23:49 -0400
Andrew, that makes sense, but the scenario I am trying to solve doesn't seem
to work. I am generating a dynamic list of account functions into an array
and binding this array to a DataList. I am trying to retrieve the name of
the text that was selected from the list. I can get the index of the list
with:

dataindex = objArgs.Item.ItemIndex.ToString();

but how do I actually get the list item name. It is neccessary to obtain the
text name value because the index number will not always correlate to the
same name. I am trying to find this information by using the OnItemCommand
of the List Box control. Thanks for your help. Rich

The DataList has the SelectedItem, not the DataListItem.

When I try string dataitem = objArgs.Item.SelectedItem.ToString();
I get the following error:
System.Web.UI.WebControls.DataListItem' does not contain a definition
for
'SelectedItem'

Have you tried

string dataitem = objArgs.Item.SelectedItem.ToString();

SelectedItem is one of the properties of DataList.

void Button_Click(Object sender, EventArgs e)
{ 
 if (DataList1.SelectedItem != null)
 {
  DataList1.SelectedItem.ForeColor = System.Drawing.Color.Red;
 }
}

Could someone tell me how to extract the value a DataList control Item.
I can extract the index, but I need to extract the value of the item
selected. Thanks in advance. Rich

Index code:
string dataindex;
dataindex = objArgs.Item.ItemIndex.ToString();
Item Value:
string datavalue;
datavalue = ?????????
