You don't need to add a link button.
You need to add

DataKeys, a comma separated list of fields from GridView4 Dataset
Enable row selection

Add a row selection handler

<asp:GridView ID="GridView4" runat="server" 
              AutoGenerateSelectButton="True"
              OnSelectedIndexChanged="GridView4_SelectedIndexChanged"
              DataKeyNames="XXX,YYY,ZZZ">

   ...
</asp:GridView

Alternatively, the above can all be done in the code behind.

Selecting a row will fire the event handler where you retrieve the data Keys

    protected void GridView4_SelectedIndexChanged( object sender, EventArgs e )
    {
        // Retrieve data from selected row
        String field1 = (String) GridView1.SelectedDataKey.Values[ "XXX" ];
        int field2 = (int) GridView1.SelectedDataKey.Values[ "YYY" ];
        double field3 = (double) GridView1.SelectedDataKey.Values[ "ZZZ" ];

        PopulateYourOtherGridviewDataSource(field1, field2, field3);
        GridViewOther.DataBind();
    }

Even in a fully dynamic scenario, if *"Grid2"* is to be populated by selections from *"Grid1"* there needs to be some agreement, at least on data type and field position in order to populate the second grid — fnostro, Dec 12 '16 at 17:52
