No, you can't. The web is stateless. Every postback creates a new instance of that page class, which is then destroyed when the page is sent. webform1 does NOT exist if it's not visible. There's nothing to interact with. You pass values between pages by putting them on the URL or storing them in the session. The URL way is far better, it creates pages that rebuild themselves and can be bookmarked, and does not use server resources. Sometimes, you do need to use the session tho.

When ever you open a pop window , you can get the reference of the parent.
Once the login is successful, you cna pass a success indicator to the parent.
In the function where you might have called the pop up window, check for this indicator and then check the Text to Log Out at the client side using javascript.

Hi anumole,
I am sorry but I did not get it.
Even a pseudocode will help if you could demonstrate a bit.
Thank You!

Hi
I have an iframe which displays inside a pdf document, but when I display the page in a different screen resolution, say 800 x 600, the pdf document expands and overlays itself over other controls.
Is there away, to control the size of the iframe so it stays the same size?
Here is my markup

Hi all,
I am using windows authentication in my web application.
I use SqlRoleProvider for implementing role management.
After the authentication is done the navigation menu is generated based on the SqlRoleProvider.
The above Role management works fine if the user has a single role assigned to him.
How to handle the role management if the user is mapped against multiple roles.
for example : the role clerk has access to create screen and the role admin has access to approve screen
If a user is assigned role as clerk and admin he should be able to view both the screens. how can I achieve this.
Is there any way I can dynamically generate the navigation menu.

I've done this in the past, but I never use the MS generated drivel, it always seems to end with hitting a brick wall unless you start by deciding your app will look and feel the way they decided it should. Perhaps you need to write your own permissions system ? It's not difficult.

You mean you need to know proper connectionstring to connect to the database ?? 
For connectionstring you can refer to

I guess you are talking about ASP.NET not Classic ASP.
If you are not able to connect database, please check the ConnectionString. Make sure Server Name given properly.

Hi,
I have some code in javascript, which i dont want to execute on page refresh.
How can i check that page is refresh using javascript
Thanks in advance

Page refresh means the page will be again retrieved from the server.
If one presses ctrl +f5 it will even remove browser cache and then load everything.
so if you want to restrict running a function on page refresh, it will automatically blocked on first run, as it would be unable to check if it is run first or refreshed.
One thing that you can do, is set a cookie in the browser after the page is loaded for first time, then from serverside remove the script when cookie is present.

Hi,
Why do you want to know the page is refresh, or what do you want to do?
If you just want to check the page is refresh, I suggest you creat a variable and change its value when the page is postback,
and use js to check it.

hi sir
i want to display the image in gridview column.and path i have from database.so iam using following.
<asp:imagefield headertext="Product" dataimageurlfield="Product_Image" controlstyle-width="100" controlstyle-height="100">
product_image is a column of database which conatin the path of images.but it does not display the image .
please help me.
|

I think the path in the database doesnt maps with your virtual directory.
You must specify a path which the client can directly point, means path relative to virtual directory.
check view-source to see what is the path rendered in the client side.

|

Can you look at the page source and see if the image urls are being read correctly from the DB.
Also check if the server has access to the locatin of the images.

Hi Vikas,
I think you want to set the image url, so try this....
(Based on the idea that you have told the gridview to have a Template Field)
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("Product_Image") %>' />
So you would place it inside a template field like below.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:TemplateField HeaderText="Product_Image" SortExpression="Product_Image">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("Product_Image") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="ProductTitle" HeaderText="ProductTitle" SortExpression="ProductTitle" />
<asp:BoundField DataField="ProductDesc" HeaderText="ProductDesc" SortExpression="ProductDesc" />
</Columns>
</asp:GridView>
I think this is what you might mean.
Hope it helps
Rob
