Your best solution is here.

Use OnClientClick instead of OnClick event

i.e
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return validation();" />

and Javascript

<script language="javascript" type="text/javascript">
function validation()
{
if(document.Form1.textbox1.value=="")
{
alert("please fill it");
return false;
}
}
</script>

HI.

U can use
Button.Attributes.Add("onClick","function();");
but out of Ispostback

U can also call javascript function by onclientClick event in source code

If u call by Onclientclick plz remove code from codebehind file.

execute SQL statement.....and fill a DataSet with your information

if you use ACCESS as a database and VB.NET as your language then follow...

Dim mySql AS String="SELECT * FROM myTable"<br />
<br />
//Suppose you have a DataAdaptor(da) And DataSet(ds)<br />
Dim ds As DataSet<br />
Dim da As OleDbDataAdapter<br />
 <br />
da = New OleDbDataAdapter(mySql, myConnection)<br />
ds = New DataSet<br />
da.Fill(ds)<br />
<br />
//set DatSource of your datagrid to the dataset<br />
DataGrid1.DataSource=ds

well! isnt there any need to use data reader??
well my code is

//connection as conn

strQuery = " SELECT * FROM table";
SqlCommand com1 = new SqlCommand(strQuery, conn);

DataSet ds=new DataSet();
SqlDataAdapter da=new SqlDataAdapter();

SqlDataReader dr = com1.ExecuteReader();

if (dr.Read())
{

da.Fill(ds,"table");

}

its not working i mean data is not displaying in the grid..and the exception that is shown is

"The SelectCommand property has not been initialized before calling 'Fill'."

why are u using datareader and dataset simultaneously???
follow this...

'1. Create a connection<br />
    Dim myConnection as New SqlConnection(<br />
          ConfigurationSettings.AppSettings("connectionString"))<br />
<br />
    '2. Create the command object, passing in the SQL string<br />
    Const strSQL as String = "SELECT * FROM myTable"<br />
    Dim myCommand as New SqlCommand(strSQL, myConnection)<br />
<br />
    'Set the datagrid's datasource to the datareader and databind<br />
    myConnection.Open()<br />
    DataGrid1.DataSource = myCommand.ExecuteReader(<br />
                              CommandBehavior.CloseConnection)<br />
    DataGrid1.DataBind()

but keep in mind

A datareader is a read-only object. If you need to edit and update changes you need to use a dataset.

sorry shamaila I have forgotten that yours a windows application...
then you have to make a datatable with that datareader and bind it to the datagrid....

i dont see any other option for you..

Here is a databind for a grid view in windows application:

//...
SqlConnection conn = new SqlConnection(connectionString);
conn.Open();
string strQuery = "SELECT * FROM tableTest";
SqlCommand com1 = new SqlCommand(strQuery, conn);

DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(com1);
da.Fill(ds, "table");

dataGridView1.DataSource = ds;
dataGridView1.DataMember = "table";
//...

I hope it works...it worked when I've tested it Smile | :)
