I am having an image button which has been placed inside a gridview.
Please find below my grid view :
<asp:Content ID="MainContent" ContentPlaceHolderID="MainContentPlaceHolder" runat="Server">
<asp:UpdatePanel runat="server" ID="UP">
<asp:GridView ID="ExpensesGridView" runat="server" AutoGenerateColumns="False"
BorderColor="#004B9D" BorderStyle="Solid" BorderWidth="1px"
CellPadding="4" ShowFooter="True"
DataKeyNames="TimesheetId" Width="700px"
onsorting="ExpensesGridView_Sorting" CssClass="Gvplacement">
<asp:TemplateField HeaderText="Select for Approval" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox ID="chkApprove" runat="server" />
</ItemTemplate>
<FooterTemplate>
Approve:</FooterTemplate>
<FooterStyle HorizontalAlign="Center" />
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<ItemStyle HorizontalAlign="Center" />
<FooterTemplate>
<asp:ImageButton ID="btnApprove" runat="server" ToolTip="Click to approve selected expenses"
ImageUrl="~/App_Themes/Default/Images/buttons/icon_16x16_tick.gif" AlternateText="Approve"
CommandName="Approve" />
</FooterTemplate>
<FooterStyle HorizontalAlign="Center" />
</asp:TemplateField>
</GridView >
</ContentTemplate>
</asp:UpdatePanel>
As I am new to jquery,I am not able to get the buttonId.
I have to create a jquery function which will be called when we click the image button.
Purpose of the function:
Check if any check box is selected and if so , an alert message has to be displayed.
