Call Javascript method from code behind

Question

0.00/5 (No votes)

See more:

I have a function in Javascript which makes a label invisible. I want to call this function from the code behind. I am not able to make it invisible. Here are both the lines of code.

Code behind:

C#

ClientScript.RegisterStartupScript(GetType(), DateTime.Now.ToString(), "MyFunction();", true);

Javascript:

JavaScript

function MyFunction()
       {
           document.getElementById("<%= Label8.ClientID %>").style.display = 'none'; 
       }

Pls let me know if there is any mistake. Looks like control is not going to method definition only.

Thank you

Solution 2

check if there are multiple RegisterStartupScript blocks on your page.
If yes then you will have to name each script block differently

check clientscriptmanager.IsStartupScriptRegistered for that and in that case you can overload RegisterStartupScript
