Display or conceal a Div element within a Web Application

I need to toggle the visibility of a label inside a div based on the value of another text box using JavaScript. The function is functioning properly, but in the ASP.NET code-behind, I am using a select case statement to set the visibility of the DIVid to either True or False during page load.

The issue arises when the JavaScript function for hiding the div only works if the initial visibility of DIVid is set to true during load. Other parts of the JavaScript function, such as disabling a text box, are working correctly.

I suspect that this problem occurs because the script cannot find the DIVid element when its visibility is initially set to false. How can I resolve this issue?

javascriptc#asp.net

Answer №1

By utilizing DIVid.Visible = false in ASP.NET, you prevent the control from being rendered and therefore cannot be manipulated through Javascript.

In the event that you need to manage visibility from the server side, you can include attributes in this manner:

DIVid.Attributes.Add("style","display:none;");

Answer №2

Ensure your div remains hidden without using the .net control visibility property.

document.getElementById("yourDiv").style.display = "none";
