What does the message say ? What code generates it ? What have you done to follow the instructions the exception message gave you ?

It's a simple update profile page containing a form with loaded value.
Whenever the page is opened those msg are coming.
SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
What should I do to fix this?

Hi,
I want to create a file using FileStream, but I want the user selects the file Location on its machine to be saved.
How can I show a dialog Box for selecting a path.
I don't need a control with browse, just open a save as dialog and I create the file in the selected path
Best wishes

That shows your level of knowledge in web applications.

As Navaneeth said, the problem is that you have absolutely no idea what you are doing. Buy a book on ASP.NET and read it.

Could you please give me a short sentence about the complicated point of my post !?
I want user downloads a file, but the file is created run-time, not an available file on server.
I've exported an Excel file of a GridView data, now I can save it in a fix path on client (e.g. C:\1.xls), the thing I want is to ask the user about the path to be saved?
Best wishes

That is the problem. ASP.NET works on server and can't show dialog boxes on client machine. It is browsers job to show the save dialog box and you don't have any control over it.

Oh!
Are you familiar with products of DevExpress, Telerik, ... or just you know Microsoft products?
There are a lot of Controls that have both server-side and Client-Side capabilities, the Client-Side can be connected to Server-Side ones ...
Ok ,Take it easy. I'm not going to have an argument about it, maybe I'm wrong, but you can say in soft words.
Thank you for your attention.

Oh!
I said I don't need a control. I just need a smart code to enforce the browser to show dialog, and I use the selected path.

I reiterate. It is totally controlled by the browser.

I don't think I was rude. But if you are hurt, honestly, that was not my intention.

If you feed a file down from the server, the client will be prompted the path to save to. Always. Your post seems to indicate that you have no idea about the seperation between server and client, what happens on the server, and what happens on the client. If you save the file to the client, they will be asked where to save it, every time.

I am using asp.net ajax tab control in my project. I found an issue with it. In my page there are four tabs, each tab contains a list of controls. When page loads, I want to set focus on first tab’s (which is set as active tab) first control. .I am not able to do it either using server side code or client side code.
Following java script code is used to set the focus on page load:
Sys.Application.add_load(function()
{
document.getElementById("<%=txtQuestion.ClientID %>").focus();
});
With above code I got following java script error:
Can’t move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus.
I need help on this.

Hi
I have a number of pages that have gridviews in them and which use different queries. However, in the gridviews I have buttons, which use icons based upon the values held in the database. Is there a way in which I can move this code into a class object rather than having to repeat the code a number of times in each gridview's row bound method?
Thank you in advance.

Sure - just make the control take one of the objects that you bind a row to, so you can specify that when you add the control to a row.

Yes you can have a class that handle the case.
Another aletrnative approch to look would be UserControl. Do the gridview have the similar (or the same) formatting and behaviour? Of course the query as you stated is different. Look if you can create a UserControl then you can use this. In the UserControl class, you can customize anything you want.

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Hi
Thanks for replying.
I like your approach about the User Control, because you are quite correct about the controls. They do use the same formatting and behaviour. To excuse my ignorance, do you have an example on how to pass the values from the built in gridview round bound method to the user control and still have the button appear in the gridview as if it is part of it? I am still fairly new to ASP, and I am still finding my feet, any assistance you can give me would be deeply appreciated.
Thanks in advance

I didn't get your question. What is build in griedview round bout method? UserControl is similar to Page. You can handle any griedview events in the user control code behind. Can you explain your question.

you mean asp.net. They are completely different.

Hi
In the gridview component there is a method called onRowDataBind, which is built in method in the gridview. This is where I have been looking at my data from the query to build up my ImageButtons. Sorry, if I confused, by was using the past tense, which is bound.
Going back to my question, in the onRowDataBind method, you have access to all the methods and classes associated with the rows, and where I have tried to say something like e.row.backcolor, this will not work because. So, how do create a user control class which is defined outside of the gridview, I can pass parameters from the onRowDataBind, and can interact with it when a user clicks on the button in the gridview?
On the last part of the question, when the user clicks on an ImageButton, I am using command name and command argument on the buttons. Do these still need to be part of the gridview, because command name sits inside the gridview tag and allows me to know which button on the row the user has click on?
Thanks in advance
