it must display OrderDetails and Customer Dfetails on seperate gridviews i achieved that now i want to have an "All" option in that combobox when ALL is selected it display all ordersDetails and Customer Details from database.Note I got tables which are ordersDetails and Customer Details they have foreign key from Orders table.I retrieve data using a foreign key but now option ALL doesnt have foreign key thats the problem that i am facing

Solution 1

For all statement don't need to Where Condition
It will show all data.
No need to foreign key.

Like as...

SELECT CustomerName,CustomerName,
FROM Orders inner join OrderDetails on Orders .ID = OrderDetails.orderRef

Try...........

My problem how do i bind those gridviews to ALL option becouse is in the same combobox with other option that have WHERE Clause

Are you use ComboboxColumn in your grid view or display normal in data table???

I use grid view to display only, i just have a combobox that i select from on top of the page

Retrieve the DataTable from your sql with
"SELECT CustomerName,CustomerName,
FROM Orders inner join OrderDetails on Orders .ID = OrderDetails.orderRef"

and store in dt.

dt is the DataTable Object

and write in cs file
gridview1.DataSource = dt;
gridview1.DataBind();

I hope your problem will solve......

hi you can try this ,

XML

<asp:GridView ID="grd" runat="server" CaptionAlign="Top" Width="100%" SelectedIndex="0" CellPadding="4"
                   AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px"
                              GridLines="Vertical" ForeColor="Black">
                  <Columns>

                      <asp:TemplateField HeaderText="Select Record">
                          <ItemTemplate>
                           put controls here like:
  <asp:label id="lblLabel" runat="server" text="<%# Bind("tableColumn") %>" xmlns:asp="#unknown"></asp:label>
                              </ItemTemplate>
                      </asp:TemplateField>
</Columns>

Apply join query on both tables assign the result into some dataTable which is having result of all data.
assign it to grd.DataSource and call grd.DataBind();

this will be the one way where you can bind the columns of query result to the gridview...
Or you can retreive join result and simply use following logic.

some DataTable object=result of your join query; //or you can use dataAdapter and Dataset also
grd.DataSource=some table;
grd.DataBind()
