>>Hi everybody,
>>
>>Thanks to Paul I got the first part of my page working (or at least it seems to work in few tests I made).
>>
>>Now I'm up to the next "challenge".
>>
>>When I click on Edit button in my grid I show user's info in a separate table and hide the grid. I have Save button with server code and I have a Cancel button, which, I believe, should only hide the table and show the grid.
>>
>>So, I'm trying the following code in Page_Init (what better method should I use - this one fires too often)?
>>
>>

>>protected void Page_Init(object sender, EventArgs e)
>>    {
>>        this.btnCancelProfile.Attributes["onclick"] =
>>"HideElement('" +
>>this.tblProInfo.ClientID +
>>"');ShowElement('" + this.grdvwUsers.ClientID + "');" ;
>>    }

>>
>>However, the Hide part seems to be working, but the show part doesn't.
>>
>>Here is my code in Master.js file (which I added to Master page):
>>
>>

>>function HideElement(what)
>>{
>>alert(what);
>>var x = document.getElementById(what);
>>alert(x);
>>if (x) {
>>  x.style.display = 'none' ;
>>  }
>>  return true ;
>> }
>> function ShowElement(what)
>>{
>>alert(what);
>>var x = document.getElementById(what);
>>alert(x);
>>if (x) {
>>  x.style.visibility='visible'; ;
>>  }
>>  return true ;
>> }

>>
>>Do you see what is wrong?
>>
>>Thanks in advance.

I'll try that tomorrow, but it looks like my problem lies somewhere else. The second alert was showing null though the ID seemed to be OK. Not sure why I can not retrieve it properly.
