Make sure that in the following line, you have data in the datatable

C#

DataTable dtMeta = this.GetData(page);

This exception occurs when you don't have rows in the datatable but you are trying to get data from a column or row.
I believe you may be getting exception in the following line

C#

description.Content = dtMeta.Rows[0]["Description"].ToString();

How to resolve:
Check the query you are using to retrive data. Check the value in the parameter.

SQL

SELECT Title, Description, Keywords FROM Titles__Metatags WHERE LOWER(Page) = LOWER(@Page)";

Hope, it helps :)

Solution 1

The error says, there is no row in your dataTable to read , better you check Whether the DataTable have values or not before you read it.

Solution 2

check the row count before you read row data, for example

C#

if(dtMeta.Rows.Count  > 0 ){
      this.Page.Title = dtMeta.Rows[0]["Title"].ToString();
      // your other code....
}
