    {
        try
        {

            if (DropDownListFeeds.SelectedItem.Value == "All")
            {
                SPWeb web = SPContext.Current.Web;

                SPSiteDataQuery query = new SPSiteDataQuery();

                query.Lists = "<Lists>" +
                              "<List ID=" + web.Lists.TryGetList("StaffNews").ID.ToString() + " />" +
                              "<List ID=" + web.Lists.TryGetList("CompanyNews").ID.ToString() + " />" +
                              "<List ID=" + web.Lists.TryGetList("ManagementNews").ID.ToString() + " />" +
                              "</Lists>";


                query.ViewFields = "<FieldRef Name=\"Title\" />" +
                                   "<FieldRef Name=\"Date\" Nullable=\"TRUE\"/>";
                query.Query = "<OrderBy><FieldRef Name='Modified' Ascending='FALSE'></FieldRef></OrderBy>";
                query.Webs = "<Webs Scope=\"SiteCollection\" />";

                query.RowLimit = 10;

                DataTable dt = web.GetSiteData(query);
                DataView dv = new DataView(dt);



                GridViewNewsFeed.DataSource = dv;
                GridViewNewsFeed.DataBind();



            }
        }

        catch (Exception x)
        {

            Label1.Text = x.Message;
        }

    }

Abowe Date and Title i have a Dropdownlist and a Button the code above are for the button.

the code for what happens when i press linkbutton in the first grinview and display it in the other grindview looks like this.

protected void LinkButton1_Click(object sender, EventArgs e)
    {


        SPWeb web = SPContext.Current.Web;

        SPSiteDataQuery query = new SPSiteDataQuery();

        query.Lists = "<Lists>" +
                      "<List ID=" + web.Lists.TryGetList("StaffNews").ID.ToString() + " />" +
                      "<List ID=" + web.Lists.TryGetList("CompanyNews").ID.ToString() + " />" +
                      "<List ID=" + web.Lists.TryGetList("ManagementNews").ID.ToString() + " />" +
                      "</Lists>";


        query.ViewFields = "<FieldRef Name=\"Title\" />" +"<FieldRef Name=\"Authors\" />"+"<FieldRef Name=\"Links\" />"+"<FieldRef Name=\"Contents\" />"+
                           "<FieldRef Name=\"Date\" Nullable=\"TRUE\"/>";
        query.Query = "<OrderBy><FieldRef Name='Modified' Ascending='FALSE'></FieldRef></OrderBy>";
        query.Webs = "<Webs Scope=\"SiteCollection\" />";

        query.RowLimit = 10;

        DataTable dt = web.GetSiteData(query);
        DataView dv = new DataView(dt);



        GridViewShowMore.DataSource = dv;
        GridViewNewsFeed.DataBind();


    }

This is a ASP.Net Question more than a Sharepoint one. You dont have to use Connected web parts as that is used for something completely different. (Passing rows of data using a consumber/subcriber type of model).

Anyways, coupld of ways to do this, and the shortest would be:

<asp:LinkButton Text="text" runat="server" ID="LinkButton1" 
    onclick="LinkButton1_Click" />   

protected void LinkButton1_Click(object sender, EventArgs e)
{
    TypeOfYourOtherWebpart Ctrl = this.Page.FindControl("YourOtherControlID") as TypeOfYourOtherWebpart;
    TypeOfYourOtherWebpart.MyData = "SomeValue";
}
