Hi, I have a paged gridview (Apts_grd) tied to an Access DataSource
(Apts_srcGrd). How do I get the total number of data records returned by the query? The following shows only the number of records per page: Apts_srcGrd.SelectCommand = "SELECT * FROM tblApts WHERE ..." Apts_grd.DataBind() Response.Write("Count: " + Apts_grd.Rows.Count.ToString TIA, Mark |

-- Call ExecuteNonQuery to send command
int count = (int)cmd.ExecuteScalar(); The query in the SqlCommand constructor obtains the count of all records from a table. This query will only return a single value. The ExecuteScalar method returns this value. Since the return type of ExecuteScalar is type object, we use a cast operator to convert the value to int. Hope that helps Patrick <msch-prv> wrote in message news:7760 [..] |

You can do that automatically,
you always need to count records on the DataSet itself --------------------------------------- Sub BindSQL() Dim MyConnection As SqlConnection Dim DS as DataSet Dim MyCommand As SqlDataAdapter Dim RcdCount As Integer 'Our SQL string Dim sqlStr As String = "SELECT titles.title, authors.au_lname, " & _ "authors.au_fname, titles.price " & _ "FROM authors INNER JOIN titleauthor ON " & _ "authors.au_id = titleauthor.au_id " & _ "INNER JOIN titles ON " & _ "titleauthor.title_id = titles.title_id" 'The connection to our database Dim strConn As String = "server=(local);uid=sa;pwd=;" & _ "database=pubs;Trusted_Connection=yes;" 'Open up our connection with our connection object MyConnection = New SQLConnection(strConn) 'To execute our Sql Statement and provide our active connection MyCommand = NewSqlDataAdapter(sqlStr, MyConnection) 'Create instance of DataSet object and fill our predetermined 'datagrid with it and we name it DS = new DataSet() MyCommand.Fill(DS, "pubs") RcdCount = DS.Tables("pubs").Rows.Count.ToString() RecordCount.Text = "<b><font color=red>" & RcdCount & "</font> records found" Pubs.DataSource = DS Pubs.Databind() lblPageCount.Text = "Page " & Pubs.CurrentPageIndex + 1 & " of " & Pubs.PageCount End Sub --------------------------------------- you can see this link to have a better idea http://www.developerfusion.co.uk/show/4060/2/ |
