2nd Popup Issue In SharePoint 2010 Visual Web Part (With Ajax Update Panel)

I need to popup an alert for the user 2 times based on his/her option picked.
 
Business scenario:
If user choose to deleting a master record, 1st popup and alert the user his/her action.
And if (s)he choose to delete, now I have to find if any child records effecting, if so, not to delete the main record but alert the user again for further action.

This is how I solved it: With the help of JavaScript and Server events.
Added two delete buttons on webpart designer
  1. Main Delete:
                   <asp:Button ID="btnDelete" runat="server" Text="Delete" Width="100px" OnClientClick="if(confirm('Are you sure you want to delete this saved record?')==true)return true;else return false;" CausesValidation="false" onclick="btnDelete_Click" class="ms-ButtonHeightWidth" ChildrenAsTriggers="true"/>            
 2. Hidden Delete: (using style to hide)
                        <asp:Button ID="btnDeleteConfirm" runat="server" Text="DeleteConf" Width="100px" CausesValidation="false" onclick="btnDeleteConfirm_Click" class="ms-ButtonHeightWidth" style="display:none" />
 
OnClientClick event of the Main delete button prompt for 1st initial popup. Once he/she choose to say YES, onclick="btnDelete_Click" will fire as coded in javascript function.
Now in the btnDelete_Click event if I find any child records (I am using entity framwork here) I will register and call ConfirmDelete()

protected void btnDelete_Click(object sender, EventArgs e) {
.
.
if(entityList.Count > 0)
{
   RegisterPopupScript();
ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "PopupDelete", "ConfirmDelete();", true);
}else
{MasterSalesRepService.Delete(Convert.ToInt32(lblSalesRepId.Text));
RedirectPage();
}
}

private void RegisterPopupScript()
        {
            Type type =
this.GetType();
            if (Page.ClientScript.IsStartupScriptRegistered(type, "
PopupScript"))           
               
return;
                       
            System.Text.
StringBuilder script = new System.Text.StringBuilder();
script.Append("<script language=\"javascript\" type=\"text/javascript\">\n");
script.Append("function ConfirmDelete(){if(confirm('Do you want to delete child record(s) as well?')==true) return document.getElementById('" + btnDeleteConfirm.ClientID + "').click(); else  return false; }");
script.Append("
</script >");                      
           
ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "PopupScript", script.ToString(), false);          
        } 

protected void btnDeleteConfirm_Click(object sender, EventArgs e)
        {
            DeleteXrefSalesRep();
            DeleteMasterSalesRep();
            RedirectPage();
        }

In the script I will fire "btnDeleteConfirm_Click" only if user proceed other wise I won't
Note: I won't delete main record as well as child record if user cancels the action as you see from my btnDelete_Click code.

Attaching & Debugging to a specific w3wp.exe

Very common thing we developers do or run into is attaching all the w3wp.exe process while debugging.

Simply because we don't know which service a/c or IIS process to be attached while debugging.
Now in my case, as shown below I have to confirm (7 times) attachment of process, right! That's another fold to the debugging process.

 














Save the grief by use this little script to know your exact web application and attach to it irrespective of service A/C.
 
@ECHO OFF
cls
c:\Windows\System32\inetsrv\appcmd list wp

Save the above as wp.bat and store in C:\windows\system32 folder, I am choosing this because the path already added to the Environmental variable's path, which means now I can call this file from any command prompt path/folder location.

I will be invoking the script from H:\> by typing "wp" and enter.
Results shown as below & In my case I will be only attaching to 9044.

Happy debugging!
