    copied!<p>I'm paging data using an <code>ObjectDataSource</code> and I have the following method:</p> <pre><code>public int GetNumberOfArticles(string employeeIds) { System.Data.DataTable dataTable; System.Data.SqlClient.SqlDataAdapter dataAdapter; System.Data.SqlClient.SqlCommand command; int numberOfArticles = 0; command = new System.Data.SqlClient.SqlCommand(); command.Connection = Classes.Database.SQLServer.SqlConnection; command.CommandText = @"SELECT COUNT(*) FROM [Articles] WHERE [Articles].[EmployeeID] IN (@EmployeeIds)"; command.Parameters.AddWithValue("@EmployeeIds", employeeIds); numberOfArticles = (int)command.ExecuteScalar(); return numberOfArticles; } </code></pre> <p><strong>EmployeeID</strong> is an integer and because of that, anything I place inside <code>employeeIds</code> will be converted to an integer. However, because I'm using the <code>IN</code> keyword, it is obvious that i want to replace <code>employeeIds</code> with a list of ids separated by commas:</p> <pre><code>1, 2, 3 </code></pre> <p>But when I replace the line:</p> <pre><code>command.Parameters.AddWithValue("@EmployeeIds", employeeIds); </code></pre> <p>with something like:</p> <pre><code>command.Parameters.AddWithValue("@EmployeeIds", "1, 2, 3"); </code></pre> <p>I receive an exception because I provided a string while <code>EmployeeIds</code> is an integer. So, how would i go about doing that?</p> <p>thanks.</p> <p><strong>Edit:</strong></p> <p>From the replies, I understand that this has to be done manually, however the class which contains this method would be created automatically by the <code>ObjectDataSource</code>. So how can i provide the values of <code>employeeIds</code> at runtime?</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
