I am trying to develop an asp c# gridview that has select so that I can display additional details of the record. I also need a check box to allow the user the check the row for further processing. I can achieve each separately but not together. Is it even possible?

Of course it is possible.
For the column of check boxes, use TemplateField column, https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.templatefield%28v=vs.110%29.aspx
In data grid, aspx:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBoxProcess" runat="server" />
</ItemTemplate>
</asp:TemplateField>
In code behind:
protected void ButtonProcess_Click(object sender, EventArgs e)
{
foreach (GridViewRow item in GridView1.Rows)
{
CheckBox chk = (CheckBox)item.FindControl("CheckBoxProcess");
if (chk != null)
{
if (chk.Checked)
{
// This record should be processed
}
}
}
}
The GridView has build in row select functionality, you can enable it by setting AutoGenerateSelectButton property to true:
<asp:GridView ... AutoGenerateSelectButton="true" />
However, it is more user friendly to select the row when user clicks on it (rather than clicking on the link). To do this, you need to attach a bit of java-script to the row:
void GridView1_RowCreated(Object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" + e.Row.RowIndex.ToString())
}
Here is also, much better explained solution for row click select:

You can use template fields and just add the controls into them.
<Columns>
<asp:TemplateField>
<ItemTemplate>
<select />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<checkbox />
</ItemTemplate>
</asp:TemplateField>
</Columns>

Sorry i wasn't clear. I just want the row select-able with a click. And that click to fire the select method in code behind. As well as having a checkbox that when clicked fires its own method in code behind.

Apologies for the misunderstanding. I haven't ever met this as a requirement, so I'm not familiar enough with the code to give you a great answer. I did, however, find a web page which I believe covers what you're trying to accomplish here. Hopefully you find it helpful! Selecting GridView Row by clicking anywhere on the Row
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="SelectChk" OnCheckedChanged="chk_Click1" runat="server" AutoPostBack="true" />
</ItemTemplate>
</asp:TemplateField>
And in the CS code:
protected void chk_Click1(object sender, EventArgs e)
{
CheckBox MChk = sender as CheckBox;
GridViewRow MyGridR = MChk.NamingContainer as GridViewRow;
GridView1.SelectRow(MyGridR.RowIndex);
}
