aspx thread: Accessing Drop Down List From a Datagrid

Message #1 by "Hugh McLaughlin" <hugh@k...> on Thu, 20 Feb 2003 21:00:50

Hello everyone and thanks for your help in advance.  I am working on an 
application that requires the use of two drop down lists embedded within 
a datagrid.  There will also be a submit button for each record in the 
grid.  I am unsure as to how to go about accessing the drop down list for 
the particular row of the button that was clicked.  Any help would be 
greatly appreciated.  Thanks.

I'm not sure what you're planning on doing once you get a handle to the 
dropdownlist, but within the itemdatabound event search the cell that the 
dropdownlist resides in (assuming you know cell that is) ... something like 
this should work...

(in your itemdatabound event handler...)

// item, alt item, or edit item
if(e.Item.ItemType == ListItemType.Item ||
     e.Item.ItemType == ListItemType.AlternatingItem ||
	  e.Item.ItemType == ListItemType.EditItem)
{

myValue = ((DataRowView)e.Item.DataItem).Row.ItemArray[x];
//(where x is the index of the value being returned in your recordset)


// get a handle on the dropdownlist & select correct item
DropDownList ddl = (DropDownList) e.Item.Cells[y].Controls[z];
//(where y is the cell index, and z is the control index)
// now you have a handle to the dropdownlist, so select the item ...
ddl.Items.FindByValue(myValue.ToString()).Selected = true;
}


Hope that helps.

Thanks for the response. Dave.  You lost me a little bit thought.  Why do 
we need an array?  What I am trying to accomplish is to obtain the 
selected item values in the dropdown list of the row that was clicked.  
I'm confused.

Again, thanks for the feedback and patience.

Hugh,

 

All you need to do is in the function/sub you need the value do the
following

 

  DropDownList1.SelectedItem.Text() gives you the selected item

Carlos,

Thanks for the effort, but this control is located in a datagrid.  Thus I 
need to reference the proper row for the control.
