specified cast is not valid

[Guest]

Hello all,

Can some please help with an error I'm having. I'm binding a Hashtable to a
Repeater and on the ItemDataBound event i have this code:

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
DataRowView dataRowView = (DataRowView)e.Item.DataItem;

string j = dataRowView[0].ToString();
}

but I'm getting the error, "specified cast is not valid".

at the below line:

DataRowView dataRowView = (DataRowView)e.Item.DataItem;.

Thanks all.

Jon

Hi Jon,

Try this:
object dataRowView = (DataRowView)e.Item.DataItem

and then inspect the object dataRowView in a debugger - it will tell you the
type.

Thanks for the reply <iha, the below line of code fixed it:

DictionaryEntry dataRowView = (DictionaryEntry)e.Item.DataItem;

Thanks,

Jon
