sqldatasource default value

问题

How do I set the default value of a SQLdatasource parameter to the select all

<asp:Parameter Name="original_lastsaved" Type="string" defaultvalue="???"/> 

Thanks for the help. saurabh

You can do like...

SqlDataSource1.SelectParameters["original_lastsaved"].DefaultValue = "Set Value here";

Edit: If you want that when you click the Select All button, it will pick up all of the record and ignore the where clause parameter, then make an overloaded with no parameter and then clear the Select parameter in SQLDataSource Selecting event. e.g.

protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
    SqlDataSource1.SelectParameters.Clear();
}
