Yeah, my mistake.
John Simmons / outlaw programmer wrote: When the user clicks a button to submit data, I want the gridview to show the new data. I tried calling DataBind()
Use triggers in the update panel. Assume you have button named "btnSubmit", the trigger can be written like
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" />
</Triggers>In the "btnSubmit"'s click event handler,
yourGrid.DataSource = GetValues();
yourGrid.DataBind();
You have to use this kind of triggering only if the button is placed outside of updatepanel If button is inside the panel, you don't need to write these kind of triggering. It will be handled automatically.

hai.
currently i m using asp.net with c# 2005 (2.0 framework).
here i have created a page with 50 fields (mixture of labels, textbox, dropdown box, image controls).
The thing is when user select the 1st two field (both are dropdowns) then only all the other fields should enable for the user. we can user the disable property and do it. but to do for 48 fields is too risky.
So is there anyother way to put a layer (or screen) over the 48 fields where user cant use the fields before selecting the dropdowns?
guide me.
thanks in advance - KARAN

Hi , yes you can do it . In aspx page you create table and put all 48 fields under this table .
and done table visible = false.
and visible true at the IInd dropdownlist selection event.
<table id="table1" runat="server" visible="false">
your all fields
</table>

thanks sneha. but the thing is i already used nearly 10 tables to segregate the fields, so implementing the tables will become more critical for me. Is there any control in .net 2005 to proceed my work?
guide me.
thanks in advance - KARAN

....Or place them in a div and toggle the visibilty.

Anyone please help me
I have a program which converts a .txt file to PDF file . I am getting the following error while running the program
Error
'C:\Documents and Settings\........' is not a valid virtual path in ASP . NET
I give my Code below ...
code in button Click
---------------------------
String fileName = "";
String strText = "";
// create instance of the PDF manager
IPdfManager objPDF = new PdfManager();
// Create new document
IPdfDocument objDoc = objPDF.CreateDocument(Missing.Value);
// Add a page to document. Pages are intentionally small to demonstrate text spanning
IPdfPage objPage = objDoc.Pages.Add(300, 300, Missing.Value);
// use Arial font
IPdfFont objFont = objDoc.Fonts["Arial", Missing.Value];
fileName = Path.GetFullPath(fileUpload1.PostedFile.FileName);
try
{
strText = objPDF.LoadTextFromFile(Server.MapPath(fileName));
}
catch (Exception ex)
{
Response.Write("error is "+ex.Message);
}
// Parameters: X, Y of upper-left corner of text box, Height, Width
IPdfParam objParam = objPDF.CreateParam("x=10; y=290; width=280; height=280; html=true");
while (strText.Length > 0)
{
// DrawText returns the number of characters that fit in the box allocated.
int nCharsPrinted = objPage.Canvas.DrawText(strText, objParam, objFont);
// HTML tag generated by DrawText to reflect current font state
String strHtmlTag = objPage.Canvas.HtmlTag;
// The entire string printed? Exit loop.
if (nCharsPrinted == strText.Length)
break;
// Otherwise print remaining text on next page
objPage = objPage.NextPage;
strText = strHtmlTag + strText.Substring(nCharsPrinted);
}
// Save document, the Save method returns generated file name
String strFilename = objDoc.Save(Server.MapPath("mask.pdf"), false);
lblResult.Text = "Success! Download your PDF file <A HREF=" + strFilename + ">here</A>";

Says it all really. ASP.NET cannot access your C: drive. It can only access its own virtual directory.

Give permissions to IISWPG user group. Notice that it can cause security leak.
