gridview에서 행을 업데이트하려고하는데 다음과 같은 오류가 발생합니다. 'ProductName' 선택한 데이터 원본에서 찾을 수 없습니다.'ProductName'이름의 필드 또는 속성을 선택한 데이터 소스에서 찾을 수 없습니다.
Northwind 데이터베이스를 사용하고 있습니다.
이protected void gvProducts_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
SqlConnection connection = new SqlConnection();
connection.ConnectionString = ConfigurationManager.ConnectionStrings["myConnection"].ConnectionString;
SqlCommand command = new SqlCommand();
command.Connection = connection;
command.CommandText = "UPDATE Products SET ProductName = @ProductName WHERE ProductID [email protected] ProductID";
command.Parameters.AddWithValue("@ProductID", Convert.ToInt32(gvProducts.DataKeys[e.RowIndex]["ProductID"]));
TextBox tb = (TextBox)gvProducts.Rows[e.RowIndex].Cells[0].Controls[0];
command.Parameters.AddWithValue("@ProductName", tb.Text);
int effect = 0;
try
{
connection.Open();
effect = command.ExecuteNonQuery();
}
catch (Exception ex)
{
}
finally
{
connection.Close();
gvProducts.EditIndex = -1;
gvProducts.DataBind();
}
if (effect != 0)
fillDetailed();
}
데이터베이스 방식은 다음과 같습니다 :

'ProductName'이라는 열이 있습니까? – Rahul
예, Northwind 데이터베이스에 그러한 열이 있습니다 –
Ca'products' 테이블에 대한 스키마를 게시 하시겠습니까? – Rahul
