Hi jayachitra ,

Have a look at my sample,

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DataSourceSelectArguments arg = new DataSourceSelectArguments();
           DataView dv =  this.SqlDataSource1.Select(arg) as DataView;
           this.GridView1.DataSource = dv;
           GridView1.DataBind();
        }
    }
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            GridView inner = e.Row.FindControl("GridView2") as GridView;
            DataSourceSelectArguments arg = new DataSourceSelectArguments();
            DataView dv = this.SqlDataSource1.Select(arg) as DataView;
            inner.DataSource = dv; inner.DataBind();
        }
    }
    protected void GridView2_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView self = sender as GridView;
        self.PageIndex = e.NewPageIndex;
        DataSourceSelectArguments arg = new DataSourceSelectArguments();
        DataView dv = this.SqlDataSource1.Select(arg) as DataView;
        self.DataSource = dv; self.DataBind();
    }

    <form id="form1" runat="server">
    <div>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="countryid"
            Width="320px" OnRowDataBound="GridView1_RowDataBound">
            <Columns>
                <asp:BoundField DataField="countryid" HeaderText="countryid" ReadOnly="True" SortExpression="countryid" />
                <asp:BoundField DataField="countryname" HeaderText="countryname" SortExpression="countryname" />
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:GridView ID="GridView2" runat="server" AllowPaging="True" PageSize="2" OnPageIndexChanging="GridView2_PageIndexChanging">
                        </asp:GridView>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
    
    </div>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>"
            SelectCommand="SELECT * FROM [country]"></asp:SqlDataSource>
    </form>

Re: Triggering events in the child grid

Dear Manish,

Thank you for your valuable reply.

Actually I am using c#, I have added the paging change event handler, event though the event is not triggered.

I kept a button inside the child grid and triggered the event, that is also not working.

Is there any other way to resolve this?

Hi,

You can attach the handler like below. Its for the Button click event inside another control. You can do it for Grid control inside the Main Grid Item created event.

AddHandler btnAdd.Click, AddressOf AddNew_Click

Triggering events in the child grid

jayachitra — Thu, 10 Jul 2008 09:30:09 GMT

Dear All,

I have a grid view in my application, which contains child grid for each and every row bounded to it.

I want to have paging in the child grid and I have assigned an event handler for it in the code while binding it to the main grid.

But it is not triggered.

Can any one help me to resolve this issue?

Thanks a lot in advance.
