Hi -

I have a data bound grid and when a row is clicked I need the value out of the first cell of the row that was clicked. I'm not exactly sure how to achieve this on a data grid. Here is the code for the data grid. Ideally what I want is when the row is clicked get the value of the first cell so in the code behind I can pass that value as a parameter in a store procedure.

<asp:datagrid id=dgListaDistributori runat="server" CssClass="tblDGStandard" Width="100%" HeaderStyle-VerticalAlign="Middle" HeaderStyle-Height="20" ShowHeader="True" AutoGenerateColumns="False" OnPageIndexChanged="PageGrid2" AllowPaging="True" CellSpacing="1" CellPadding="0" BorderWidth="0px">  <AlternatingItemStyle CssClass="tblDGStandardAlt"></AlternatingItemStyle>
	 <Columns>
		 <asp:BoundColumn DataField="DISV_CODDIS" HeaderText="Cod.Distr.">
			<ItemStyle Height="20"></ItemStyle>
							                <HeaderStyle CssClass="tblDGStandardHeader" Width="60"></HeaderStyle>
						                </asp:BoundColumn>
						                
						                <asp:BoundColumn DataField="DISV_NAZIONE" HeaderText="Naz.">
							                <ItemStyle Height="20"></ItemStyle>
							                <HeaderStyle CssClass="tblDGStandardHeader" Width="20"></HeaderStyle>
						                </asp:BoundColumn>
						                				
						                	
						                <asp:TemplateColumn HeaderStyle-CssClass="tblDGStandardHeader" HeaderStyle-Width="20">
                                            <ItemTemplate>
                                                <asp:ImageButton id="btnCancelDis" Runat="server" ImageUrl="img\delete.gif" CommandName="CancellaDis"></asp:ImageButton>
                                                <ajaxToolkit:ConfirmButtonExtender ID="ajaxCBE1"  runat="server" TargetControlID="btnCancelDis" />                                                               
                                            </ItemTemplate>
                                        </asp:TemplateColumn>
                                        <asp:TemplateColumn HeaderStyle-CssClass="tblDGStandardHeader" HeaderStyle-Width="20">
                                            <ItemTemplate>
                                                <asp:ImageButton id="switchAccount" Runat="server" ImageUrl="img\refresh.png"  CommandName="logOut"></asp:ImageButton>                                                
                                            </ItemTemplate>
                                        </asp:TemplateColumn>
</Columns>
					               
</asp:datagrid>

Based on what is listed above, you need to create an event handler for the OnSelectedIndexChanged event - see below;

ASP.NET

<asp:datagrid id="dgListaDistributori" runat="server" cssclass="tblDGStandard" width="100%" headerstyle-verticalalign="Middle" headerstyle-height="20" showheader="True" autogeneratecolumns="False" onpageindexchanged="PageGrid2" allowpaging="True" cellspacing="1" cellpadding="0" borderwidth="0px" xmlns:asp="#unknown"> OnSelectedIndexChanged="gListaDistributori_SelectedIndexChanged"></asp:datagrid>

In your code behind you can then access the cell value as follows;

VB

Dim strMyValue as String
strMyValue = dgListaDistributori.SelectedItem.Cells(1).Text
