Window.print problem

Hi Guys,
I am using web grid on my page to show spreadsheet. On this page I have print button which call javascript function window.print(). But by calling this I am getting javascript error:

Microsoft JScript runtime error: Unable to get value of the property ‘currentStyle’: object is null or undefined

It looks like that webgrid override the print function so if I call window.print() it goes straight into acwmain.js file at line "var originalViewPanelOverflow=xViewPanel.currentStyle.overflow;"

Could you please help me to get ride this problem, I need to use window.print() function along with web grid on page.



I think you may call the method provided by GridWeb i.e. GridWeb.print() on the client side (in JavaScript), see the demos on how to do the scripts on the client side:

And for your issue, could you create a sample project, zip it and post it here to show the issue, we will check it soon.

Thank you.

Thanks Amjad,
I have build the demo for you in which you can see the print button having javascript ‘window.print()’ which causing this problem.

Let me know if anything else you need.



Thanks for creating a demo.

We have logged this issue in our database. We will look into it and provide you a solution or fix asap.

This issue has been logged as CELLSNET-40480.


It looks you are using some older version of the product. Could you give it a try our latest version of GridWeb v2.7.4.xxxx, you may get the version installing our latest version of Aspose.Cells for .NET v7.1.2:

We also evaluate your issue in the mean time.

Thank you.

No I used latest version and still same problem.



Thanks for testing it with latest version.

I have logged your comment against the issue id: CELLSNET-40480


After investigation, we found that you are not using the latest acw_main directory.

Please use the latest acw_main directory and more specifically use the latest acwmain.js file

I have packaged it, you can find it from this link:
for GridWeb v2.7.4.2000

Please also note that we override print method, so clients can use

gridwebid.print() method to print.

Suppose, your control name is “MainContent_GridWeb1”, so you can call print method in javascript like this.


I just tested with latest version but no luck :(.

And to make it clear I do not want to use gridwebid.print() method instead just default window method, so could it be possible to do that?


Did you use the latest acwmain.js file?

Please attach it here, so that I could make sure you are using the latest one.

Please use webgrid.print() method instead of window print method because it has overriden the window print method.

Probably, you will have to override webgrid.print method if you want to bypass it.

The file is attached. Could you explain how would I re-override the webgrid.print method?


Please use something like this to use the print function.

<asp:Button onClick = “<% this.GridWeb1.ID %>.print();return false;” …/>


We have made the following changes in your demo files.

Demo.Master file:


<script type="text/javascript">
var newprint = window.print;



<a href="#" onclick='javascript :newprint(); return false;'>print function by default</a>
<a href="#" onclick='<%=this.GridWeb1.ClientID%>.print(); '>print function by gridweb</a>

If you want to use default print function of window.print; you can try “newprint();”

If user want to use default print function by gridweb, you can try <%=this.GridWeb1.ClientID%>.print();

Please add Aspose.Cells for GridWeb DLL when you build the project.

Thanks Shakeel, much

How can I get to use the gridweb print on chrome correctly, the javascript I used for IE does not seem to work for chrome?

gridRV = document.getElementById('<%= gwRV.ClientID %>');
