Question

This is my javascript method in .aspx file. I want to invoke this method from code-behind based on a certain condition:

function confirmboxAndHideMessage() {
    //HideMessage();
    var response = confirm("are you sure?.");
    if (response == true) {
        document.getElementById("<%=chkValidated.ClientID%>").checked = true;
        HideMessage();
    }
    else {
        HideMessage();
        return true;
    }
}

The condition upon which I want to invoke is something like this:

        if (obj.fkValidationStatusId.HasValue && obj.fkValidationStatusId.Value.Equals(1))
        {
            btnProceedAddNewRecords.Attributes.Add("OnClick", "javascript:return confirmboxAndHideMessage();");  
        }
        else
        {
            btnProceedAddNewRecords.Attributes.Remove("OnClick");
        }

This condition is being exercised in a method which is called in PageLoad event inside

if (!IsPostBack) { /* condition */ }

It is not working and my guess is that the way i am adding the method in button attribute is wrong. My request is that, kindly suggest a way I can invoke this javascript method from my code-behind based on the stated condition. If you think that my approach is flawed, Please do suggest Alternatives. Thanks.

Answer 1

use to set/unset OnClientClick

if (obj.fkValidationStatusId.HasValue && obj.fkValidationStatusId.Value.Equals(1))
  {
     btnProceedAddNewRecords.OnClientClick="return confirmboxAndHideMessage();";  
  }
else
  {
     btnProceedAddNewRecords.OnClientClick="retun false;";
  }
