this is how we did it.....we filled it with objects through an object data source. You can get your source from anything though (pasting code here sucks....)








%26lt;asp:ObjectDataSource ID=';ObjectDataSource1'; runat=';server'; SelectMethod=';GetAllOrders';


TypeName=';DBAccess';%26gt;


%26lt;FilterParameters%26gt;


%26lt;asp:QueryStringParameter DefaultValue=';'; Name=';SearchParam'; QueryStringField=';Search';


Type=';String'; /%26gt;


%26lt;asp:QueryStringParameter DefaultValue=';'; Name=';CategoriesParam'; QueryStringField=';Cat';


Type=';Int32'; /%26gt;


%26lt;/FilterParameters%26gt;


%26lt;/asp:ObjectDataSource%26gt;


%26lt;asp:GridView ID=';GridView_Orders'; CssClass=';datagrid'; runat=';server'; AllowPaging=';True'; AutoGenerateColumns=';False';


DataSourceID=';ObjectDataSource1'; PageSize=';15'; BackColor=';White'; BorderColor=';#CCCCCC';


BorderStyle=';None'; BorderWidth=';1px'; CellPadding=';3'; OnSelectedIndexChanged=';GridView_Orders_鈥?br>

%26lt;Columns%26gt;


%26lt;asp:CommandField ShowSelectButton=';True'; /%26gt;


%26lt;asp:BoundField DataField=';OrderID'; HeaderText=';OrderID'; SortExpression=';OrderID'; /%26gt;


%26lt;asp:BoundField DataField=';CustID'; HeaderText=';CustID'; SortExpression=';CustID'; /%26gt;


%26lt;asp:BoundField DataField=';OrderDate'; HeaderText=';OrderDate'; SortExpression=';OrderDate'; /%26gt;


%26lt;asp:BoundField DataField=';ShipDate'; HeaderText=';ShipDate'; SortExpression=';ShipDate'; /%26gt;


%26lt;asp:BoundField DataField=';Shipper'; HeaderText=';Shipper'; SortExpression=';Shipper'; /%26gt;


%26lt;asp:HyperLinkField DataTextField=';Cost'; DataTextFormatString=';{0:c}'; HeaderText=';Cost'; /%26gt;


%26lt;/Columns%26gt;


%26lt;FooterStyle BackColor=';White'; ForeColor=';#000066'; /%26gt;


%26lt;RowStyle ForeColor=';#000066'; CssClass=';datagrid'; /%26gt;


%26lt;SelectedRowStyle BackColor=';#669999'; Font-Bold=';True'; ForeColor=';White'; /%26gt;


%26lt;PagerStyle BackColor=';White'; ForeColor=';#000066'; HorizontalAlign=';Center'; /%26gt;


%26lt;HeaderStyle BackColor=';#006699'; Font-Bold=';True'; CssClass=';datagrid'; /%26gt;


%26lt;/asp:GridView%26gt;

















Then for your connection string....we put that in the web.config file. Looks something like this.








%26lt;?xml version=';1.0';?%26gt;


%26lt;configuration xmlns=';http://schemas.microsoft.com/.Net鈥?br>

%26lt;appSettings/%26gt;


%26lt;connectionStrings%26gt;


%26lt;remove name=';LocalSqlServer';/%26gt;


%26lt;add name=';LocalSqlServer'; connectionString=';Data Source=192.168.11.11;Initial Catalog=Ecommerce1; User=namehere;Password=ttGurVBx'; /%26gt;


%26lt;/connectionStrings%26gt;


%26lt;/configuration%26gt;
