Several times while developing web applications we need to implement functionality to delete bulk / multiple rows or records in Gridview using checkbox to select rows / records to be deleted with confirmation dialog box.
By using following code you can achieve it <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" ShowFooter="true"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:CheckBox ID="chkSelect" runat="server" /> </ItemTemplate> <FooterTemplate> <asp:Button ID="btnDelete" runat="server" Text="Delete" OnClick="btnDelete_Click" OnClientClick="return DeleteConfirmation();"/> </FooterTemplate> </asp:TemplateField> <asp:BoundField DataField="ID" HeaderText="ID" SortExpression="ID" /> <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" /> <asp:BoundField DataField="Location" HeaderText="Location" SortExpression="Location" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [ID], [Name], [Location] FROM [Details]"></asp:SqlDataSource>

Hello,
Dominoes is a series of popular board games of skill played with tiles. Dominoes is a 2-player game of skill using 28 dominos where each player gets 7 dominos at start. There are 3 variations: Five-Up (aka Muggins or All Fives), Draw and Block. The goal in dominos is to be the first to get the agreed-upon number of points (100 - 500). In Five-Up, points are scored during the play by making the exposed ends of the domino chain total to a multiple of five. The winner at the end of each hand also scores points for all the pips remaining in the other player's hand. Players can select 7-bone or 9-bone hand variations. Under the 1968 UK Gaming Act, games classified as forms of skill (non-gambling) include dominoes, cribbage, chess, and bridge. And if you are having a problem about Dominoes tricks and How to recording top scores.Gamecolony can help you find what you need. Thanks _____________________ Dominoes |
