You can use LinkButton for this.
HTML:
<asp:LinkButton ID="LinkButton1" runat="server" OnClick="Click" CommandArgument='<%# Eval("CompanyAdRedirectURL") %>' Text="Click" />
C#:
protected void Click(object sender, EventArgs e)
{
//save Click Event the redirect
Response.Redirect(LinkButton1.CommandArgument);
}
To open in a new window:
protected void Click(object sender, EventArgs e)
{
//save Click Event the redirect
Page.ClientScript.RegisterStartupScript(this.GetType(), "OpenWindow", "window.open('" + LinkButton1.CommandArgument + "','_newtab');", true);
Response.Redirect(LinkButton1.CommandArgument);
}
