Clicking the Button Without Refreshing the Page ASP.NET Webform

I want to search for the value we wrote in the textbox without refreshing the page. But when the button is clicked, the page is refreshed. The solutions below did not work. Can you help me?

Cause

The page is being refreshed because the button click event triggers a postback to the server, causing the entire page to reload.

Solution

To achieve the desired behavior of searching without refreshing the page, you can use AJAX and the UpdatePanel control in ASP.NET Webforms.

Wrap the content that needs to be updated without refreshing the page inside an UpdatePanel control. In this case, the textbox and the button should be placed inside the UpdatePanel.
```
    
        
        
    
    
        
    
```

Add the necessary JavaScript code to handle the search functionality without refreshing the page. In this case, the code is using jQuery to detect when the textbox is in focus and trigger a click event on the hidden button.
```
$(document).keyup(function (e) {
    if ($('#<%=rulosParNoTx.ClientID%>').is(":focus")) {
        $("#<%=rulosParNoBt.ClientID%>").click();
    }
    return false;
});
```

With this setup, when the button is clicked, only the content inside the UpdatePanel will be refreshed, and the rest of the page will remain unchanged.
