Gridview User Control event not firing

I have a gridview user control that does everything I need it to except for one thing. I can NOT get the SelectedIndexChanged or Changing events to fire. I have put it in the user control but still cannot get it to fire so that I can use it for my needs. I do have this code on RowDataBound

'e.Row.Attributes("onclick") = Page.ClientScript.GetPostBackClientHyperlink(myGridview, e.Row.Cells(7).Text & "|" & e.Row.Cells(5).Text & "|" & e.Row.Cells(8).Text)
            'e.Row.ToolTip = "Click to select this row."

Open in new window

and my markup code is
   <asp:GridView ID="gvGeneric" runat="server" AutoGenerateColumns="false" AllowPaging="true"
        AllowSorting="True" SelectedIndex="0"
        OnSorting="GridView_Sorting" 
        OnRowDataBound="GridView_RowDataBound" 
        OnDataBound="GridView_DataBound" 
        OnRowDeleting="GridView_RowDeleting"        
        OnRowEditing="GridView_RowEditing" 
        OnRowUpdating="GridView_RowUpdating"
        OnRowCancelingEdit="GridView_RowCancelingEdit"  
        OnSelectedIndexChanged="GridView_SelectedIndexChanged"
        OnSelectedIndexChanging="GridView_SelectedIndexChanging"
        PagerSettings-Visible="false" Width="95%">
       
        <RowStyle HorizontalAlign="Center" Height="25px" CssClass="hover_row" />
        <AlternatingRowStyle HorizontalAlign="Center" CssClass="hover_row"/>
        <EditRowStyle cssClass="GridViewEditRow" />

        <EmptyDataRowStyle Height="40px" HorizontalAlign="Center" />
        <EmptyDataTemplate>
            <b>No Data Found</b>
        </EmptyDataTemplate>

    </asp:GridView>

Open in new window


I wanted to mention the RowDataBound but Im not sure if that is going to help anyone fix my issue but thought I would mention it anyway.
If anyone needs anymore info please ask.
Thanks in advance...

from MSDN....
The SelectedIndexChanged event is raised when a row's Select button is clicked, but after the GridView control handles the select operation. This enables you to ...

and you dont have
autogenerateselectbutton="True"

Open in new window

so the select button never shows up.

also can create your own Select button in any location...
<asp:buttonfield buttontype="Button"
                CommandName="Select"
                 headertext="Select Item"
                 text="Your Custom Text"/>

i add my own buttons in cells and trap those clicks.

snip from my app...  I use a commandfield as the first column.. this triggers the SelectedIndexChanged event.

        <asp:GridView ID="GridViewProjList" runat="server" AllowSorting="True" 
            AutoGenerateColumns="False" DataSourceID="ODS_Projects" 
            onselectedindexchanged="GridViewProjList_SelectedIndexChanged" 
            HorizontalAlign="Center" style="text-align: center">
            <Columns>
                <asp:CommandField ButtonType="Image" SelectText="--&gt;" 
                    ShowSelectButton="True" SelectImageUrl="~/images/pick-r.png" />

Open in new window

.

    protected void GridViewProjList_SelectedIndexChanged(object sender, EventArgs e)
    {
        // Get the currently selected row using the SelectedRow property.
        GridViewRow row = GridViewProjList.SelectedRow;

        // Display the company name from the selected row.
        // zero based columns
        //MessageLabel.Text = "You selected " + row.Cells[2].Text + ".";
        string ProjId = row.Cells[1].Text;

Open in new window



in another area, i use a Hyperlink field to create a link to details page. no Select button.

protected void GridViewProjDocs_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            // determine the value of the Hyperlink field
            HyperLink hlDocId = ((HyperLink)e.Row.FindControl("HyperLinkDocId"));
            Label filelinks = (Label)e.Row.FindControl("LabelFileLinks");
            Label Title = (Label)e.Row.FindControl("lblTitle");
            
            CheckBoxList chkFiles = (CheckBoxList)e.Row.FindControl("cklstFiles");

            DataRowView row = (DataRowView)e.Row.DataItem;

            //build the link to Document details page
            hlDocId.NavigateUrl = String.Format("details_prjdoc.aspx?DocNo={0}", row["DocNo"]);
            hlDocId.Text = row["DocId"].ToString();
