Hi ,
I want to get the hiddenfield value in masterpage (pageload event).
I assigned the hiddenfield value in javascript by following code.
function GetNavigationId(id) {
     document.getElementById('<%=hdNavicationText.ClientID %>').value = id;
     var text = document.getElementById('<%=hdNavicationText.ClientID %>'); 
     alert(text.value);
  }


This script was working correctly.

But I cannot get the value of hidden field in pageload event and page Init event.

Javascript function alert box gives the exact value But In pageload I can get only null values.

I also try HiddenField hid1 = (HiddenField)Page.MainContent.FindControl("hid1");


What I have to do Please guide me?

Are u not able to get the value for the first load or in next postback? because in first load only after server side code finishes execution js will run so you wont be able to get.

Are you able to get the hiddenfield object in master page?

yes,but the value is empty..

1 solution

This is happening because your child page will not be rendered as it is when used with master pages that is why Java script not able to find value.

Please do view source and find your hidden filed and see what is your hidden filed id .
.NET adds string like 'ctl00_hdnField' before your hidden filed name .

Where 'hdnhdnField' is your hidden file id and 'ctl00' is addend by asp.net.
so what you have to do is find your id and put in above way.

Example In JavaScript Coding

function Test()
{

alert(document.getElementById('ctl00_hdnField')value);

}
