Changing LabelText via Java Script

[vivekphlp]

I have a label in my aspx page & iam changing its text via document.getElementById("LabelID").­ innerHTML = "SOmeText"; from JAVASCRIPT. Now by default an ASP.NET label should retain its contents. But its not. IS there any way to make it so I can change a label on the client-side and the contents persists back to the server? If iam using a textbox it does works fine.

I have not tried this. Just a wild guess. Try changing to ­innerText.

document.getElementById("LabelID").­innerText = "SOmeText";

Navaneeth, I think the controls which don’t have the ‘name’ attribute wouldn’t maintain its contents on post back.

AFAIK, there is no way to get the value on server which is changed by JS for a label. Label is rendered as HTML span and the values of HTML elements like this are not posted to server. If you know CSS, you can make a text box look like a label and change the text box value. Please ignore my previous reply.

For server controls, the id will be put as name. So what you are saying won't occur. The real issue here is a label render as HTML span and contents of span will not be posted to server. See my latest reply. :)

Use <asp:hiddenControl to change its value. Anything other than input types are reflects its changes through javacript in server (Not even Serverside ReadOnly/Disabled TextBoxes). So even if you change the innerHTML of the control, you will not find it in server side. Rather use

document.getElementById("hiddeninput").value = "SOmeText"; // To find the value in server
document.getElementById("LabelID").innerHTML = "SomeText"; // For display purpose only.

I hope this will help you. :rose::rose:

Of course budd. Just add a Textbox. In the server side add:

txtbox.Attributes.Add("readonly", "readonly");

This will make the textbox readonly and also reflect any data being changed in the client. If you make

txtbox.Readonly = true / txtbox.Enabled = false;

the textbox value changed in the client will not reflect in the server. Hope you understand. :rose:
