Try using the FileUpload Control

and the command FileUpload1.PostedFile.SaveAs(SaveToAddress);

you should check if a file was really sent before trying to save it Smile | :)

<br />
if(FileUpload1.PostedFile != null)<br />
{<br />
 //handle the incoming file<br />
}<br />

I'm not sure, but I think you should play around with viewstate. You can set EnableViewState property of your textboxes to false, or you can set this property to be false for whole page, if you don't need viewstate at all. Or you can override LoadViewState or SaveViewState methods of your Page class. Or you can simply go through all controls and if a control is type of TextBox set its text to ""

<br />
foreach(System.Web.UI.Control control in Page.Controls)<br />
{<br />
	SetTextBoxesText(control);<br />
}<br />
<br />
public void SetTextBoxesText(System.Web.UI.Control control)<br />
{<br />
	if (control.GetType() == "System.Web.UI.WebControls.TextBox")<br />
	{<br />
		((System.Web.UI.WebControls.TextBox)control).Text = "";<br />
	}<br />
	foreach (System.Web.UI.Control childControl in control.Controls)<br />
	{<br />
		SetTextBoxesText(childControl);<br />
	}<br />
}

Passing Values between 2 forms

Dear All

i made a webform that contains a listbox, and a pop up window.
the pop up window contains two text boxes, what i want is to know how can i pass the values of the text boxes to the parent form to ass them to the listbox?

i want the first textbox to be the listitem's text and the second textbox to be the value of that listitem

i know i should use java script (maybe window.opener ...) but i need some clues to do the implementation

Thanx everyone

Best Regards

suppose i put the values in a session variable, would they be moved between forms?
i mean i'll assign the session value from the pop up window and i want to read it from the parent window.
another thing, how will i add the list item to the listbox of the parent page?
suppose i want to reload the form again, in this case it will only add the last list item only and the previous ones will be lost

hope there is another way

This is my code, where I open modal dialog to create new category entry (in parent page):

public static string OpenCreateCategoryModalDialog(string url)<br />
{<br />
	return @"<script type='text/javascript'>"<br />
	+ "function CreateCategory(){"<br />
	+ "ret = window.showModalDialog('" + url + "');"<br />
	+ "document.getElementById('hdnCategoryReturn').value = ret;}"<br />
	+ "</script>";<br />
}

you have to register it using

Page.RegisterClientScriptBlock("OpenMocalDialog", MyJavascript.OpenCreateCategoryModalDialog(modalDialogUrl));<br />

and call it when user clicks on button.

then in child modal dialog, you have to add to your submit button attribute:

submitButton.Attributes.Add("OnClick", "javascript:window.returnValue = #myreturnValue#")

replace #myReturnValue# with javascript that gets values from your textboxes. you can separate these values by semicolon or something, so you can get them from hidden field and split them on parent page in event handler.

I hope you understand what I mean Smile | :)

Well, I suppose you have a button, that opens modal dialog. this button has assigned javascript function on client side (it opens modal dialog, waits until this dialog returns a value and then stores it into hidden field) and it has assigned event handler on server side (this is always called afetr client side javascript - it causes postback, so you can be sure, value is already stored in hidden field). You can read this value in your eventhandler for this button and add values into listbox there as well.
One more think, in modal dialog doesn't work postback, so don't use this solution, if this second page has to be more complicated with postback involved.

man it's very confusing
i couldn't implement it Frown | :(

can u give me a running sample of it or website links as tutorial to do this?

i didn't register the script because it gave me some problems so i wrote it in the aspx page in script tag
the modal dialog opens fine but when i submit the submit button opens another pop up just like itself and with the fields filled in it!

As I mentioned, you can not use postback in modal dialog. But I didn't mentioned, that because of that you can not use asp:button in modal dialog window, use <input type=button... > instead. this will not cause postback, only calls javascript assigned to this button.

yes, actually i want page B as popup window to show the record information. So, Everytime the user select a new record and click the button on page A, if page B is still openning , then B will auto refresh and show the latest record information ;or if the page B is closed, then page B will pop up again and show the latest information.
