Hi Experts,

I have a devexpress gridview bound to sqldatasource. On the selection of a row in this grid I want to pass student Matric No to second Dexexpress gridview so that it gets populate too with student data. I can get the Matric no, from the selected row but the problem I am having is to pass the selected Matric No as a parameter to the second Gridview. Any ideas how can we pass on this parameter
<dx:ASPxGridView ID="grid" runat="server" AutoGenerateColumns="False" DataSourceID="ds_Student"
                        KeyFieldName="MatricNo" ClientInstanceName="grid" OnCustomCallback="ASPxGridView1_CustomCallback">
                        <Columns>
                           <dx:GridViewCommandColumn VisibleIndex="3">
                                <SelectButton Text="select" Visible="True">
                                </SelectButton>
                            </dx:GridViewCommandColumn>
                            <dx:GridViewDataTextColumn FieldName="MatricNo" ReadOnly="True" VisibleIndex="0">
                            </dx:GridViewDataTextColumn>

                        grid.PerformCallback(e.visibleIndex.toString());
                    }

                    }" />
                    </dx:ASPxGridView>
                    <asp:SqlDataSource ID="ds_Student" runat="server" ConnectionString="<%$ ConnectionStrings:EnterpriseValeConnectionString %>"
                        SelectCommand="SELECT [MatricNo], [Forename], [Surname], [Gender] FROM [Student]">
                    </asp:SqlDataSource>


<dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False"  DataSourceID="ds_StudentDetail"
                >
            <Columns>
                <dx:GridViewDataDateColumn FieldName="DateOfBirth" VisibleIndex="0">

Code Behind is

       Session["MatricNo"] = Convert.ToInt32(values[0]);
        ASPxGridView1.DataBind();

    }

you can do this using dataset,datatables and relation. see the link below.

in example combobox is used you can use the gridview similarly.

i am talking here about dataset, datatable and datarelation. Forget about the other things.

you can see the datarelation easing the development in 3rd solution provided in this link

http://www.emoreau.com/Entries/Articles/2007/01/Setting-a-masterdetail-relationship-between-two-ComboBox.aspx

by using relation you can get the child rows from table2 depending on the foreign key column in table1 while creating the relation.

in devexpress gridviews you also set the datasource property to see the grid populated.

can you give me the code so that i can make it happen for you.
