I am having a view in that I search student details and bind it in partail view.

In partail view data is bind through a Model.

Model is empty when page load that's why its thorws null refernce error on page load.

So on pagle load my model is null.

I am calling partial view pop up through jquery ajax.

hello dear,

you can follow like as below:
@{
   if(Model.Editor!=null)
    {
        // your code here
    }
}

For example In your partial view if you are binding list please check like this

@if(Model.count>0)
{
//bind your data
}
else
{
No results found

}

For example In your partial view if you are binding not a list

@if(model.property !=null)
{
}
else
{
no results found
}

Yes I tried the same but the problem is it's a partial view and I am calling that view through Ajax so when page loads hits goes over the and null reference is handle. But next hits doesn't go over there bcoz of Ajax call

Please share your code.
If you can check model on page load whether it is null or not, you can handle the error.
