GridView get values of row 2 and 3 on linkbutton click

Question

I have a Gridview like this.

<asp:GridView ID="gvITD" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" Width="100%"
AutoGenerateColumns="false" OnRowCommand="gvITD_RowCommand">
<AlternatingRowStyle BackColor="White" />
<EditRowStyle BackColor="#2461BF" Width="1" />
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#EFF3FB" />
<SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
<SortedAscendingCellStyle BackColor="#F5F7FB" />
<SortedAscendingHeaderStyle BackColor="#6D95E1" />
<SortedDescendingCellStyle BackColor="#E9EBEF" />
<SortedDescendingHeaderStyle BackColor="#4870BE" />
<Columns>
<asp:BoundField DataField="Type of Return" HeaderText="Type of Return" ItemStyle-Width="120px" />
<asp:BoundField DataField="Quarter" HeaderText="Month" ItemStyle-Width="90px" />
<asp:BoundField DataField="Year" HeaderText="Year" ItemStyle-Width="70px" />
<asp:BoundField DataField="submittedDate" HeaderText="Date Of Submission" ItemStyle-Width="140px" />
<asp:BoundField DataField="Status" HeaderText="Status" ItemStyle-Width="120px" />
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton Text="View Details" CommandName="ViewDetails" runat="server" ></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

On click of the link button I want to retrieve the value of Quarter and Year. For this I used this code in cs file.

protected void gvITD_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "ViewDetails")
{
LinkButton lnkView = (LinkButton)e.CommandSource;
string lectureId = lnkView.CommandArgument;

        string strArg = e.CommandArgument.ToString();
        //int rowIndex = Convert.ToInt32(e.CommandArgument.ToString());
        //GridViewRow row = gvITD.Rows[rowIndex];

        //String Month = row.Cells[1].Text;
        //String Year = row.Cells[1].Text;

        //int month = DateTime.ParseExact(Month, "MMMM", CultureInfo.CurrentCulture).Month;

        //Response.Redirect("NodalOfficerInspection_V2.aspx");
        // write link button click event code here
    }

But I get nothing from e.CommandArgument and cannot proceed further

Hi @Adeel Mirza ,
e.CommandArgument only get your linkbutton's data and you don't bind it.So,you get nothing.You could do like this:

protected void gvITD_RowCommand(object sender, GridViewCommandEventArgs e)  
        {  
            if (e.CommandName == "ViewDetails")  
            {  
                GridViewRow row = (GridViewRow)((LinkButton)e.CommandSource).NamingContainer;  
                int rowindex = row.RowIndex;  
                string Quarter = gvITD.Rows[rowindex].Cells[1].Text.ToString();  
                string Year= gvITD.Rows[rowindex].Cells[2].Text.ToString();  
            }  
        }
