Select a cell value from GridView asp.net c#

I have a GridView with users and I want to be able to select the first column of a row - which is with usernames. I know how to do it with the autogenerateselectbutton property, but it doesn't look well on my design. So instead, I want to make it without the Select button. Here is what I have so far:

<asp:GridView ID="GridView5" AllowPaging="true" GridLines="None" CssClass="mGrid" PagerStyle-CssClass="pgr" AlternatingRowStyle="alt" runat="server" AllowSorting="True"
                            AutoGenerateColumns="False"
                            Width="750px"
                            CausesValidation="False" OnPageIndexChanging="gridView5_PageIndexChanging"  OnSelectedIndexChanged="gridView5_SelectedIndexChanged" autogenerateselectbutton="True" >
                            <Columns>
                                <asp:BoundField DataField="username" HeaderText="Username" ReadOnly="True" />
                                <asp:BoundField DataField="name" HeaderText="Name" />
                                <asp:BoundField DataField="lastname" HeaderText="Last name" />
                            </Columns>
                            <selectedrowstyle backcolor="LightCyan"
     forecolor="DarkBlue"
     font-bold="true"/>  </asp:GridView>

If I remove the autogenerateselectbutton, then clicking on a row does nothing.

Here is my c# code, which takes the value from this cell and stores it into a string and then i call the setUser() function with the cell value as a parameter.

protected void gridView5_SelectedIndexChanged(Object sender, EventArgs e)
{
    GridViewRow row = GridView5.SelectedRow;
    string user = row.Cells[1].Text.ToString();
    setSelectedUser(user);
}

I think the problem is in the aspx file, where I create my GridView, but don't know how to make the row selectable without the autogenerateselectbutton set to true.

if you want to get the selected index value of a particular row in which the user do any operation.then you have to get the rowindex value If you want to Get a Value From a Label Control then"

Label l=(Label)Gridviewname.rows[e.rowindex].Findcontrol("label name of which you want to get the data")
String s=l.Text;
setselecteduser(l);

if you want to get the value from TextFiled

TextField t=(TextField)GridviewName.rows[e.rowindex].FindControl("Textbox Id of which you    want to get the data")
String s=t.Text;
SetSelecteduser(t);

Put a linkbutton with Select text, command name as "Select" and pass "User name" as command argument.

<asp:LinkButton runat="server" ID="lnkStatus" CommandName="Select" 
                             CommandArgument='<%# Eval("username") %>' Text='Select' />

Now fire RowCommand event:- Get username from argument, no need to get it from grid.

Seems ok but does your page postbacking after select ? do you check postback control with if(!ispostback) because when the page is postbacking the gridview will also, it means the grv will be empty. How can u get data from empty grv you have use postback control where your datasource and databind lines...

You want to use the RowCommand method you can create a asp:ButtonField column and set the command name

   protected void GridView1_RowCommand(object sender, System.Web.UI.WebControls.GridViewCommandEventArgs e)
   {
        if (e.CommandName=="MyCommand")
        {    
             int row = int.Parse(e.CommandArgument.ToString());
             var cellText= gvOwner.Rows[row].Cells[1].Text.Trim();
        }
   }
