Hi

I have a Web User Control with a DropDownList and i have a parent page with a ListView which contains the Web User Control in the InsertItem and in the EditItem

And when i use the SelectedIndexChanged and use the sender object to tell where the Control Was sent from

DropDownList DropDownList1 = (DropDownList)sender;

I then assign it to the LIistViewDataItem

        ListViewDataItem ListView1 = (ListViewDataItem)DropDownList1.Parent.Parent;

If the DropDownList is being executed in the InsertItem of the ListView then it is coming through as ListViewItem but if it is being Executed in the EditItem It is coming thorgh as a ListViewDataItem

So this is where i'm getting an error and i need a way to test which one is coming through.

Sort of Like

If (lvAssets.Item == ListViewDataItem)
 Do Something;
else if (lvAssets.Item == ListViewItem)
 Do Something;

Is this Possible?


Thanks
John

Not sure if I understand your question, but maybe this is what you want

if (lvAssets.Item.GetType() == typeof(ListViewDataItem))

Yes. You can verify the type of it using is operator.

If (lvAssets.Item is ListViewDataItem)
 Do Something;
else if (lvAssets.Item is ListViewItem)
 Do Something;

ListViewDataItem is inheritted from ListViewItem. You can code as follows:

 
DropDownList DropDownList1 = (DropDownList)sender;
ListViewItem lvi = (ListViewItem)DropDownList1.Parent.Parent;

if (lvi is ListViewDataItem)
{
   // Do Something
}
else 
{
   // Do Something
}

Hi

USing your suggestion ii found i didnt need to detect if it was a dataitem or just an item

I could just do

 DropDownList DropDownList1 = (DropDownList)sender;
        ListViewItem ListViewItem1 = (ListViewItem)DropDownList1 .Parent.Parent;

And it worked

Thank you all for your help
