                                            <table><tr><td>
                                            <%# Eval("NewsletterName").ToString()%>
                                            </td></tr>
                                            <tr><td><asp:Button ID="btnSelectNL_Template" Text="Select" runat="server" CssClass="button" CommandArgument='<%# Eval("NewsletterId").ToString()%>' CommandName="Select"/></td></tr>
                                            </table>
                                        </td>
                                    </ItemTemplate>
                                </asp:DataList>
                            </tr>
                        </tbody>
                 </table>
            </td>
        </tr>
    </table>
</ContentTemplate>

and in the ItemCommandEvent I tried following

protected void dlTemplates_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "Select")
        {
            int SelectedNewsletterId = int.Parse(e.CommandArgument.ToString());
            if (NewsletterSelectedHandler!= null)
            {
                                         e.Item.Attributes.Add("onclick","jQuery('#mydialog').dialog('close');");
                NewsletterSelectedHandler(SelectedNewsletterId);
            }
        }
    }

EDIT

i shown the popup using this in my code behind

ScriptManager.RegisterClientScriptBlock(this.Page, Page.GetType(), "change", "jQuery('#mydialog').dialog('open');closedialog = 1;jQuery('#mydialog').parent().appendTo(jQuery('form:aspnetForm'));", true);

popup shown successfully but i could not close it on the button click of datalist child button i tried code provided by tugburk i checked the error console also there is no error
code for close is as followd :

<script type="text/javascript">
$(document).ready(function(){

    $('#ctl00_ContentPlaceHolder1_NewsletterWizard1_TemplatePicker1_dlTemplates_ctl00_btnSelectNL_Template').click(function(){

      $('#mydialog').dialog('close');

    });

  });
</script>

Any help would be appreciable
Many thanks in the Advance

Answer 1

use the following code;

  $(document).ready(function(){

    $('#<%= btnSelectNL_Template.ClientID %>').click(function(){

      $('#id_of_your_dialog_element').dialog('close');

    });

  });

EDIT :
you are hardcoding your button id there;

ctl00_ContentPlaceHolder1_NewsletterWizard1_TemplatePicker1_dlTemplates_ctl00_b‌​tnSelectNL_Template

DataList will produce multiple buttons if you have multiple records. add a class name to that button, and try to write a code against it

$('.MyButtonClass').click(function(){ 
    $('#mydialog').dialog('close'); 
});
