Forms Data Controls :: Image Not Updated Until Page Is Posted Again?
Dec 16, 2010
I have a datalist and gridview that have a image in a column.. when you click the imagebutton, its calls my method that updates a table. The page is posting during this event, but when the page is done, the image hasnt changed.. im sure it has to do with the datasource not binding during that click.. so where can i move this code to or can i simply bind the control during that click? Currently im handling it in the itemdatabound event.. which would explain it.. but where is the correct place to handle this logic?
[Code]....
The control on the page is configured like so..
[Code]....

This is the first time I've come across this kind of problem before and I'm having trouble approaching it.
I have a swf developed by someone else that posts an image and I have to create a handler of some kind to capture it, name it, then upload it to a directory. I've tried a couple ways and nothing is working.
this is a quick an dirty approach, just an aspx file
<%@ Page Language="C#" %>
<%@ Import Namespace="Components" %>
<%@ Import Namespace="System.IO" %>
<script runat="server">
public partial class upload : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string uploadDirectory;
uploadDirectory = Server.MapPath(@"images/");
string imageName = "image.jpg";
string uploadPath = uploadDirectory + imageName;
//FileUpload imageUpload = new FileUpload();
// Get the data from the POST array
string Email = Request["email"];
HttpPostedFile imageFile = _context.Request.Files["image"];
imageFile.SaveAs(uploadPath);
}
}
</script>
this is another approach using a handler.
<%@ WebHandler Language="C#" %>
using System.IO;
using System.Web;
using System.Web.Configuration;
using System.Web.IHttpHandler;
public class Uploader : IHttpHandler.i
{
public void ProcessRequest( HttpContext _context )
{
string uploadDirectory;
uploadDirectory = Path.Combine(_context.Request.PhysicalApplicationPath, @"images");
//uploadDirectory = Server.MapPath(@"images/");
string imageName = "image.jpg";
string uploadPath = uploadDirectory + imageName;
//FileUpload imageUpload = new FileUpload();
// Get the data from the POST array
string Email = _context.Request["email"];
HttpPostedFile imageFile = _context.Request.Files["image"];
imageFile.SaveAs(uploadPath);
}
}

ex: page1.aspx
from

creating ?name=mike&address=street
I want to do this without requesting all individual fields of course, just a routine

Whatever server Control we take on aspx page while in coding phase, all those controls are converted to html controls through the asp.net engine and sent to the requesting web browser. That's fine.
Now, all the controls that are rendered on the browser are html controls. I am bit confused that how after pressing any button (Or any such control that post back pages) page is posted back to the asp.net engine. How such html controls comes to know where (address) they have to go?

i want to compare my database value with my new updated value. what should i do ? e.g : on page load i am excuting one procedure which bring 10 columns and fill it against the 10 fields using for loop on the page. then i am changing value of two columns. ok. when i press update button then there is one more procedure which updates all the new and old columns into database. Its working fine. just i want to know that, should i update only two columns(which are modified) insted of updating all 10 columns ? Is there any csharp code that brings my page load columns into array and then compare it with new ones and updates only those columns which are mismatch with array. i am not sure but there is some way to do this.

I have an image file to be uploaded and to be updated in my database. I've already write the C# code based in a VB code.
However, I have some trouble to pass a data to be updated through DetailsView Control, by using
DetailsViewUpdateEventArgs e
The column in database is "ImageData"...
In VB the Code is:
e.Values(
"ImageData"
) = imageBytes
ImageBytes is an array of bytes..

Lets say you have a page with headers that tell the browser not to cache.Also, this page has already been posted back to itself.Now you hit the refresh button and you click cancel on the IE modal box with the "previously submitted..." message.You get "Webpage has expired". This doesn't happen in FF or Chrome.Is there a way to prevent the "Webpage has expired" message in IE?Since the page isn't cached, I guess IE has nothing to render.But if the page isn't cached and FF and Chrome shows it, I guess they just show the page as previously shown?

On one (aspx) page I have a GridView (GridView has multiple pages). After a user selects a row/record and clicks "edit" he's redirected to another (.aspx) page where he edits the selected record via DetailsView. fter clicking update on DetailsView he's redirected back to the page containing the GridView.What is the simplest/shortest way that the updated record is automatically selected on the Gridview (e.g. at Page_Load event)?

I have a simple grid with 5 columns. The first 4 are numeric values I have formatted with templates. The last column is a total and I've added the Update button on the end. When the Update button is pressed, I have it updating the table with the new values and calculating the Total column. My goal is to have the Total column calculated after each cell is updated and not when the Update button is pressed.
I've added CommandName="myUpdateRowTotal" to
my templates.
<ItemTemplate>
<asp:TextBox ID="R01_Item_txt" CommandName="myUpdateRowTotal" runat="server" BackColor="White"
Font-Names="Arial" Font-Size="10pt" ForeColor="Blue"
Text='<%# Bind("R01_TARGET_COMMISSION", "{0:###,###,##0}") %>'
Width="75px"></asp:TextBox>
</ItemTemplate>

There is a very common problem I am facing in my new webproject in gridview control.The sequence of the execution of the process is as follows:There are some search parameters in SearchPage with a gridview. In gridview's rows there is an Edit button.By providing search parameter(s), data populated to gridview and if we click edit button a new page opens as a popup to update record.In new page the record is updated fine. On successful updation user close the window but he goes to the Search page he again finds the same record with the same parameters to see changes it remains unchanged.Its only changed when he search another record and then again provides the previous parameters.I don't know why is this behaviour of gridview?
Any idea would be helpful.

I am writing an application in which a remote url web site ( says url1 that is sender) sends xml data to another web site (says url2 that is receiver) by using .NET WebRequest. On the receiver url2 if I use .NET Page.Response and .NET Page.Request to store posted/received xml data into an external text file, then the data is stored. However, if I store the received data into database, I do not see the data is stored into the database.
trouble shoot the codes so I can store such remotely posted data into database on the receiver side url2.
I host both url1 site and url2 site in my computer using IIS like [URL]
1/ Receiver page's codes that store remotely posted xml data into database do not work:
protected void Page_Load(object sender, EventArgs e)
{
Page.Response.ContentType = "text/xml";
StreamReader reader = new StreamReader(Page.Request.InputStream);
String xmlData= reader.ReadToEnd();
ProductNameSapce.ProductCollection.InsertReceivedProduct(xmlData).ToString(); // data is not stored ; the method is tested and works well with hard-coded data
reader.Close();
Page.Response.End();
}
2/ The version of the receiver page at url2 that stores into an external text file works:
protected void Page_Load(object sender, EventArgs e)
{
Page.Response.ContentType = "text/xml";
StreamReader reader = new StreamReader ( Page.Request.InputStream );
String xmlData= reader.ReadToEnd ();
StreamWriter s;
s= File.CreateText ( Server.MapPath(".")+@""+ Guid.NewGuid () + ".txt" );
s.WriteLine ( xmlData); // data is stored in an external text file
s.Close ();
reader.Close();
Page.Response.End();
}

So I am using a formview that gets in Update mode with a bunch of values from a sqldatasource --- but I want to fill a couple dropdowns with data from the database --- but I cannot figure out how to bind the data to the dropdown box FIRST and then select the value in that dropdown box... but I keep getting an error that the Selected value is not a part of the dropdown (I assume because the sqldatasource is trying to bind BEFORE I can get the dropdown box bound).
IE -- when I load my values, lets say a 'Crop' comes back as 'Corn' ... I want to download the available crops from the database (ie. corn, beans, wheat, okra, etc.) and then set the selected value as CORN.... SO HOW do I get the dropdown filled BEFORE I try and bind the selected value?
