maybe it helps you:

There are two ways. You can create HyperLinkField or add a Hyperlink in <asp:templatefield >
 
Ex.
<Columns>
                <asp:HyperLinkField DataTextField="LeadID" DataNavigateUrlFields="LeadID" DataNavigateUrlFormatString="LeadInformation.aspx?LeadID={0}" Text="Lead ID" />
                <asp:BoundField DataField="DateTime" HeaderText="Date Updated" />
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Bind("LeadID") + Request.QueryString("type") %>'
                            Text=""></asp:HyperLink>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
>

Open in new window


Method 2
----------------------

You can add a TemplateField in the GridView control using the Edit Column
option from the context menu when you click on the smart tag.
 
1. Add a TemplateField in the Selected Fields list.
 
2. Now Right click on the Grid and select Edit Templates. Now drop the
Hyperlink control in the ItemTemplate of the Grid.
 
3. Now bind the NavigateURL and Text property of the Hyperlink to the
hyperlink column field in the table using Data Bindings.
 
4. Now if you click on the hyperlink, it will take you to that page.

Actually i have done this by template field and row data databound. I am sure there must be a better way of doing this?

 <ItemTemplate>
                                <asp:Label ID="lblMeasure" runat="server" Text='<%# Bind("MeasDef") %>'></asp:Label>
                                <asp:HyperLink ID="hprMeasure" runat="server" Visible ="false" Target="_blank"></asp:HyperLink>
                            </ItemTemplate>

Then in row data bound

 if (e.Row.RowType == DataControlRowType.DataRow)
            {
                  Label lblMeasure = (Label)e.Row.FindControl("lblMeasure");
                HyperLink hprMeasure = (HyperLink)e.Row.FindControl("hprMeasure");

If (isChild) //ischild is method and returns true or false
{
    lblMeasure.Visible = false;
                   hprMeasure.Visible = true ;
                   hprMeasure.Text = lblMeasure.Text;
                   hprMeasure.NavigateUrl ="~/KPIs/test.aspx?OEValID=" +txtOEValID.Text .ToString();
}
 else
               {
                   lblMeasure.Visible = true;
                   hprMeasure.Visible = false;
}
}
