How to get a response from the Confirm field in the code

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 when a button is clicked. Before saving a record, I will check if this record exists in the database or not (in the code behind). If it exists, then I need to show the warning to the user as "The record already exists." Do you want to continue? "When the user clicks" Yes ", I need to continue saving the record in the code, otherwise 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 code above shows that I confirm the box with the "OK" and "Cancel" buttons. My questions

  • How can I do this “Yes” or “No” in the confirmation dialog?
  • After the user clicks “Yes” / “No”, how can I catch the answer (yes / no) and continue the rest of my program?

I searched this a lot. But could not get the right answer. Please help me with this.

You can do this in many ways:

One of them places a button on the page, makes it display: none, and when true is confirmed, start its click with js.

Like in aspx

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

on the client side, create a js function to call up a confirmation dialog, e.g.

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

}

in the code below

Code verification in some event handler

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

bthSaveData click handler to save data.

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

You can use a confirmation window in JS like this

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

-, , Yes/No , .

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

TRUE/FALSE , runat = "server", , (/). .
