You shouldn't really be trying tp make the images directly accessible outside the firewall. The best way to handle this is to create a distributed architecture in which a machine inside the firewall streams the images to a machine in the DMZ which can then be streamed to the client. A simple web service should be sufficient.
On your machine inside the firewall, create a web service that, given an image name/path, reads the file and returns a byte array representing the file data.
On the web machine, call this web service and perform a BinaryWrite of the byte array.

I have 2 Frames.One of the frame has Treeview control and another Frame will have the respective aspx page of the Node of the treeview control placed in frame.When i perform some action(eg:Adding of 'user') on the particular aspx page,that added user is added to xml.
I want the first Frame (Treeview control) to be updated.So it need to reload.
How to reload first Frame when some modifications are done in second frame using javascript.

Use cross frame navigation from the client. On way to do this is to populate a public variable from the server side with the necessary javascript after you have done what you are trying to do (update the database or whatever). Then on the client in the page load do this <%=ThePublicVariable%>. This will reload the tree frame.

Really not sure what you mean, but you can loop through all the rows in the datagrid in the server code and access whatever button you want?
|
|
|
|

we can access any button in datagrid by using this code .
you have to write this code
if u want first row ,specify '0' in Items[0]
Instead of zero u can specify any row number
Button btn = (Button) datagridname.Items[0].FindControl("buttonname");
you can get the button text by using " btn.Text ".
Response.Write(btn.Text);

In Javascript code just submit your page
eg. Form1.submit();
So that your page will get reloaded and contents of web controls will remain as it is due to view state.
In page Load event code do further processing.

Or you can directly call the javascript __DoPostback() function.

Hey... I want to create a few Validation controls, but I need to create them to two events.
I mean that in one event only half of them will gonna work, and on the other event the rest will work.
Now I think it has something to do with ValidationGroup.
Is it? and if it is, how can I check if the group is Valid inside the event?
Thanks alot.
NaNg.

Try using the Enable property for each control
i mean, on load form, the first controls group are enable and the second group disable,
The validation control for the first group will be working meanwhile the validation control for second group arent, already the first validation, disable the all the controls for first group and enable the second, right now you can validate the second group.
Try it, its just a suggest

Write a Message for the clients, Example:"Only 1000 caracters for description"
In code use
<br />
Description.Remove(1000);<br />
