Re: Error when i try to search record
Where exactly is this happening? My guess is that it is failing in your GetCustomers method because you're calling alert and assuming that response.d is defined in both instances. Try changing that to the following:
Code:
const GetCustomers = pageIndex => {
const searchTerm = SearchTerm();
$.post('SearchUploadPhoto.aspx/GetCustomers', { searchTerm, pageIndex })
.then(OnSuccess)
.fail(response => {
console.error(response);
alert('Something went wrong getting the customers');
});
}
After you rerun your code, have your developer tools open and respond with what gets printed to the console.

Re: Error when i try to search record
There's loads of code there and absolutely no e4xplanation of what you're trying to achieve, what you expect and what actually happens beyond a specific alert in JS. Please provide a FULL and CLEAR explanation of the problem, ensuring that you have actually debugged your code and that the VB part at least is doing exactly what you expect. If the VB isn't doing what it's supposed to, what's the point even looking at the ASPX page?
