Question

I have to load the data in asp:grid after filtering from two asp:dropdown list. For example following is the dropdown lists:

<asp:DropDownList ID="ddlb" runat="server" AutoPostBack="True" 
                    CssClass="ddlb" Width="100px" DataSourceID="SqlDataSource3" 
                    DataTextField="MonthYearName" DataValueField="MonthYear" 
                    onselectedindexchanged="Changed">
                </asp:DropDownList>

                <asp:SqlDataSource ID="SqlDataSource3" runat="server" 
                    ConnectionString="<%$ ConnectionStrings:ProdDB %>" SelectCommand="# some sql query">
                </asp:SqlDataSource>

<asp:DropDownList ID="asd" runat="server" AutoPostBack="True" 
                    CssClass="ddlb" Width="100px" DataSourceID="SqlDataSource4" 
                    DataTextField="MonthYearName" DataValueField="MonthYear" 
                    onselectedindexchanged="SelectedIndexChanged">
                </asp:DropDownList>

                <asp:SqlDataSource ID="SqlDataSource4" runat="server" 
                    ConnectionString="<%$ ConnectionStrings:ProdDB %>" SelectCommand="# some queries">
                </asp:SqlDataSource>

Now, When i am loading the page. It shows the above defined dropdown list. What i want to know is “how should i load the data in aspx grid using the above two dropdown filter ?”.

For example i choose A option from the first dropdown then it filter the result on the basis of it and the data will display on grid and so on…

Please tell me how should i connect the grid with these two dropdown list ?

How should i filter it ?

Answer 1

Place a grid and two drop down on the page.
Place an SQL Data Source

Provide two parameters to the sql datasource select command

Attached that sqldatasource to the gridview

Bind the two parameters of the SQLDataSource to the the two Dropdown boxes.
