I've got main page, Page1.
The Page2 is opened with javascript window.open() attributed in some Page1 button control.
So I need to refresh Page1 from Page2

Ohhh... Man... Did you mention it earlier... that your Page 2 is popup 
Or May be I missed it out.
use,
window.opener.RefereshPresentPage();

Yes, sorry, Page2 is a popup opened with window.open();
How should I call window.opener.RefreshPresentPage()?
There is a button click handler, where should I paste it?

- On Second page if changes done then set any flag in session.
- On First page poll the flag session periodically via javascript, if flag session set then submit the page throught javascript and perform operation accordingly.

but that will take some additional java script over head?

Yes you are right. I think it is a better. 
|
|
|
|
|
Oh.. Is the second page is opening in a new window.
If so, just place a Javascript in the response.
this.ClientScript.RegisterStartupScript(typeof(Page), "myscript", "<script>window.opener.document.form[0].submit();</script>");
Or just
this.ClientScript.RegisterStartupScript(typeof(Page), "myscript", "<script>window.opener.location.href = "page.aspx";</script>");
Where page.aspx is the location of the other page.
Hope it works. I didnt tried it.
|
|
|
|

Yes, it is in the new window.
How can I attach that to some web control e.g. button?
I need to click a button in the Page2 and Page1 will refresh.

Simple..
write the RegisterScript code inside the Button_click event, if you need it from the server.
Or just write window.opener.location.href = 'yourpage.aspx'; return false;
in onClientClick event.
return false will eliminate postback if you want.
|
|
|
|
|
How can I put it into the button click code?
buttonClick()
{
};

Try this :
btn.Attributes.Add("onclick", "javascript:window.opener.location.href='page1.aspx'; return false;");
write this in page_load of Page2.aspx.
So that when btn is clicked it will refresh the page1.aspx
Hope it works now. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Try changing the ContentType to application/pdf. I haven't tried this so there is every chance it won't work but you never know.

Hi everyone, I am trying to write a web method in my web service which will accept information in a hashtable and process it and again will return hashtable. I am trying to do this in C#. But it is throwing an exception that hashtable can't be serialized b'coz it implements IDictionary. Is there any solution.....
|
|
|
|
|
Yes it's write, Only serializable object can return the web method. So Implement this information in dataset and the finally return Dataset.
OR look into this Article
Hashtable becomes serialized[^]

Post this question in Database section.
|
|
|
|
|

First of all this is the Wrong Section to post this.
Are you talking about different types. If so use NVARCHAR as it takes most of the primitive data types like DateTime, Bit, Int, Float etc.
