How to handle click event of linkbutton inside gridview

Recently I have posted how to sort only current page of gridview, Scrollble gridview with fixed header through javascript, File upload control inside gridview during postback and now i am going to explain how to handle click event of linkbutton or any button type control inside gridview.

We can handle click event of any button type control inside gridview by two way first is through event bubbling and second one is directly (in this type of event handling we need to access current girdviewrow container)
Through the first way we have to work with OnRowCommand event of gridview (This event fires every time when gridview button type child raises click event.) and CommandName, CommandArgument property of gridview child controls.

Handle click event of linkbutton through event bubbling code -


<asp:GridView AutoGenerateColumns="false" runat="server" ID="grdCustomPagging" OnRowCommand="grdCustomPagging_RowCommand">
   <Columns>
       <asp:BoundField DataField="RowNumber" HeaderText="RowNumber" />
       <asp:BoundField DataField="DealId" HeaderText="DealID" />
       <asp:BoundField DataField="Dealtitle" HeaderText="DealTitle" />
       <asp:TemplateField HeaderText="View">
        <ItemTemplate>
       <asp:LinkButton runat="server" ID="lnkView" CommandArgument='<%#Eval("DealId") %>'
         CommandName="VIEW">View Deal</asp:LinkButton>
         </ItemTemplate>
       </asp:TemplateField>
   </Columns>
</asp:GridView>

protected void grdCustomPagging_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "VIEW")
    {
        LinkButton lnkView = (LinkButton)e.CommandSource;
        string dealId = lnkView.CommandArgument;
    }
}


In Second way need to work with onClick event of linkbutton, sender will always have the reference of linkbutton that raised onClick event and we have to access current girdviewrow container that can reference by NamingContainer property of linkbutton.

Handle click event of linkbutton directly click event code -


<asp:GridView AutoGenerateColumns="false" runat="server" ID="grdCustomPagging">
   <Columns>
       <asp:BoundField DataField="RowNumber" HeaderText="RowNumber" />
       <asp:BoundField DataField="DealId" HeaderText="DealID" />
       <asp:BoundField DataField="Dealtitle" HeaderText="DealTitle" />
       <asp:TemplateField HeaderText="View">
        <ItemTemplate>
       <asp:LinkButton runat="server" ID="lnkView" OnClick="lnkView_Click">View Deal</asp:LinkButton>
         </ItemTemplate>
       </asp:TemplateField>
   </Columns>
</asp:GridView>

protected void lnkView_Click(object sender, EventArgs e)
{
    GridViewRow grdrow = (GridViewRow)((LinkButton)sender).NamingContainer;
    string rowNumber = grdrow.Cells[0].Text;
    string dealId = grdrow.Cells[1].Text;
    string dealTitle = grdrow.Cells[2].Text;
}
