How to get the response from Confirm box in the code behind

I am new to asp.net/C# .I am trying to create a web application.

Below is my requirement.

I am trying to save a record on button click. Before saving the record,I will be checking if that record exist in the database or not(in the code behind).If it exist,then I need to show an alert to the user as "Record already exist.Do you want to proceed?"When the user press 'Yes',I need to continue my save for the record in the code ,else I just need to exit the save process.

//......code for checking the existence of the record    
if (check == true)
{            
    ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "script", " confirm('Record already exist.Do you want to proceed?');", true);
}
//

The above code shows me confirm box with 'OK' and 'Cancel' buttons. My questions are

  1. how can I make it 'Yes' or 'No' in the confirm dialog?
  2. After the user press 'Yes'/'No',how can I catch the response(yes/no),and proceed with rest of my program?

I have searched for this a lot.But couldn't get a proper answer.Please help me on this.

You can do this in many ways:

One is place a button on the page, make its display:none and when confirm is true, trigger its click with js.

Like in aspx

<asp:Button runat="server" ID="btnSaveData" 
     onClick="btnSaveData_Click" style="display:none;" />

in client side make a js function for calling confirmation dialog box, like 

function ConfirmSave()
{
   if(confirm('Record already exist.Do you want to proceed?')
   {
       jQuery("[ID$=btnSaveData]").click();
   }

}

in Code Behind

Your code check in some event handler

if (check == true)
{            
    ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "script", 
      "ConfirmSave();", true);
}

bthSaveData click handler for saving data.

protected void btnSaveData_Click(object sender, EventArgs e)
{
 // Code for your saving.
}

Use AJAX toolkit with modalpopupextender.

   <cc1:modalpopupextender id="ModalPopupExtender1" runat="server"  cancelcontrolid="ButtonNo" okcontrolid="ButtonYes" popupcontrolid="PNL" targetcontrolid="UrSaveButton">
   </cc1:modalpopupextender>  
   <asp:Panel ID="PNL" runat="server" Style="display: none; width: 200px; background-color: #000099; border-width: 2px; border-color: Black; border-style: solid; padding: 20px;">
     <span style="color: White; font-weight: bold">Record already exist.Do you want to proceed?</span>
       <br />
        <br />
            <div style="text-align: right;">
                <asp:Button CssClass="tbl_blue" ID="ButtonYes" runat="server" CausesValidation="false" EnableTheming="false" Text="YES" />
                <asp:Button CssClass="tbl_blue" ID="ButtonNo" runat="server" CausesValidation="false" EnableTheming="false" Text="NO" />
             </div>
  </asp:Panel>

You can Customize it as you want.

One of the workaround can be to store the TRUE / FALSE flag in control that has the attribute runat="server", depending on the choice made by user (Yes / No). And then at the backend, you can check for the value of this control.

You can use confirm box in JS like this

var ans = confirm ('Record already exist.Do you want to proceed?');
if(ans==true)
{
}
else
{
}

Secondly, to get the response in code behind, you can store the Yes/No value into a hidden field e.g.

document.getElementById('<%= hiddenField.ClientID %>').value = ans;
