hi

u refer this code

function SelectAllCheckboxes(spanChk){

// Added as ASPX uses SPAN for checkbox
var oItem = spanChk.children;
var theBox=(spanChk.type=="checkbox")?spanChk:spanChk.children.item[0];
xState=theBox.checked;

elm=theBox.form.elements;
for(i=0;iif(elm[i].type=="checkbox" && elm[i].id!=theBox.id)
{
//elm[i].click();

if(elm[i].checked!=xState)
//elm[i].click();
elm[i].checked=xState;
}
}
function DeSelectCheckBoxes(spanChk)
{
// Added as ASPX uses SPAN for checkbox
var oItem = spanChk.children;
var theBox=(spanChk.type=="checkbox")?spanChk:spanChk.children.item[0];
xState=theBox.checked;

// this means it is deselected
if(xState == false)
{
elm=theBox.form.elements;
for(i=0;i if(elm[i].type=="checkbox" && elm[i].id!=theBox.id)
{
elm[i].checked=false ;
}

}
}

function HighlightRow(chkB) {
var oItem = chkB.children;
xState=oItem.item(0).checked;
if(xState)
{chkB.parentElement.parentElement.style.backgroundColor='lightcoral'; // grdEmployees.SelectedItemStyle.BackColor
chkB.parentElement.parentElement.style.color='white'; // grdEmployees.SelectedItemStyle.ForeColor
}else
{chkB.parentElement.parentElement.style.backgroundColor='white'; //grdEmployees.ItemStyle.BackColor
chkB.parentElement.parentElement.style.color='black'; //grdEmployees.ItemStyle.ForeColor
}
}

Re: how to write write code in asp.net?

There's a much easier way if you want to use client-side code:

string script="<script>function CheckAll(){";<br />
script += "document.getElementById('" + CheckBox1.ClientID + "').checked = true";<br />
script += "document.getElementById('" + CheckBox2.ClientID + "').checked = true";<br />
...<br />
script += "}</script>";<br />
<br />
Page.RegisterStarupScript("CheckAll", script);<br />
Button1.Attributes.Add("onclick", "Checkall();return false");<br />

Obviously this code has some bad things about it (if you have 100 CheckBoxes, it gets very lengthy, and also much slower, then if you would use StringBuilder). Also for ASP.NET 2.0 use should use

Page.ClientScript.RegisterStarupScript(this, "CheckAll", script);

I just wanted to show that you can do this without writing tons of nasty Javascript, and still get it working on the client-side, and also the you DO know the client-side ID of server controls (ClientID property).

You can't get the mouse position in the code behind (you can't get any real time data from the client in code behind) because its server-side. You will have to use javascript to track the mouse and do the necessary actions.

You can safely upload to a folder where the folder does not have EXECUTE or SCRIPT permission. Additionally it ought to be outside the Virtual Directories for higher and elevated levels of protection.

Furthermore, if you can afford, you can have a virus scan enabled.

potentionaly...

it depends on what are you doing with uploaded files.
if you store them somewhere within your application domain, be sure to set iis to deny access to folder where you store these files, as anybody can upload for example aspx page with malicious code and then simply access it and execute this code...

maybe you could write little bit more about purpose of uploading files in your application, so somebody can give you more appropriate answer

I have a simple problem with master pages - please have a look:

http://home.icslab.agh.edu.pl/~martinez/asp 1.JPG[^]

The content placeholder is in the middle of the middle cell of my table. How to drag/resize it, so it would cover the whole middle cell? I don`t want my content pages to be limited to be so small.

Thank you very much for any help

Re: Simple problem

What you are showing is a design view. How content placeholders are shown in the design view has nothing to do with how they are handled when the page executes. A content placeholder has no size, but it is given a size in the design view.

You can't resize the content place holder in the design view for the simple reason that it has no size.
