i am usng ajax.net in my application. I am using a update panel in ajax.net.
update panel inside the dropdownlist. and already insert the script manager control. When run the application. then display error run time.
The control with ID 'UpdatePanel1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.
|
|
|
|
|
The ScriptManager control should be appearing first and then the UpdatePanel. Try placing the ScriptManager control above the UpdatePanel.

The easiest way would be to look for a web service to do this, but otherwise you will have to use some kind of screen scraping. Do a google search for screen scraping in asp.net and you should find plenty of articles.
If you do decide to use web services i have used

Hi
Just use File upload control that will upload the image that you want to update.
Regarding the file path FileUpload1.PostedFile.FileName will give you full path path of file from client machine
Google the subject you will find more articles on this topic
Thanks and Regards

this will help, you to upload image........
and Store the path in database
protected void Button2_Click(object sender, EventArgs e)
{
string sSavePath;
string sThumbExtension;
int intThumbWidth;
int intThumbHeight;
sSavePath = _Default.fullpath;
sThumbExtension = "_thumb";
intThumbWidth = 160;
intThumbHeight = 120;
// If file field isn’t empty
if (FileUpload1.PostedFile != null)
{
// Check file size (mustn’t be 0)
HttpPostedFile myFile = FileUpload1.PostedFile;
int nFileLen = myFile.ContentLength;
if (nFileLen == 0)
{
lblOutput.Text = "No file was uploaded.";
return;
}
// Check file extension (must be JPG)
if (System.IO.Path.GetExtension(myFile.FileName).ToLower() != ".jpg")
{

return;
}
// Read file into a data stream
byte[] myData = new Byte[nFileLen];
myFile.InputStream.Read(myData, 0, nFileLen);
// Make sure a duplicate file doesn’t exist. If it does, keep on appending an
// incremental numeric until it is unique
string sFilename = System.IO.Path.GetFileName(myFile.FileName);
int file_append = 0;
while (System.IO.File.Exists(( (sSavePath + sFilename))))
{
file_append++;
sFilename = System.IO.Path.GetFileNameWithoutExtension(myFile.FileName)
+ file_append.ToString() + ".jpg";
}
// Save the stream to disk
System.IO.FileStream newFile
= new System.IO.FileStream((sSavePath + sFilename),
System.IO.FileMode.Create);
newFile.Write(myData, 0, myData.Length);
newFile.Close();
// Check whether the file is really a JPEG by opening it
System.Drawing.Image.GetThumbnailImageAbort myCallBack =
new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);
Bitmap myBitmap;
try
{
myBitmap = new Bitmap((sSavePath + sFilename));
// If jpg file is a jpeg, create a thumbnail filename that is unique.
file_append = 0;
string sThumbFile = System.IO.Path.GetFileNameWithoutExtension(myFile.FileName)
+ sThumbExtension + ".jpg";
while (System.IO.File.Exists((sSavePath + sThumbFile)))
{
file_append++;
sThumbFile = System.IO.Path.GetFileNameWithoutExtension(myFile.FileName) +
file_append.ToString() + sThumbExtension + ".jpg";
}
// Save thumbnail and output it onto the webpage
System.Drawing.Image myThumbnail
= myBitmap.GetThumbnailImage(intThumbWidth,
intThumbHeight, myCallBack, IntPtr.Zero);
// myThumbnail.Save((sSavePath + sThumbFile));
Image1.ImageUrl = @"~\" + (string)Session["user_name"].ToString() + @"\" + sSavePath + sFilename; //+ sThumbFile;
//Directory.GetCurrentDirectory() + @"\" + sThumbFile;
// Displaying success information
lblOutput.Text = "File uploaded successfully!";
TextBox3.Text = @"~\" + (string)Session["user_name"].ToString() + @"\" + sSavePath + sFilename;// sThumbFile;
// Destroy objects
myThumbnail.Dispose();
myBitmap.Dispose();
}
catch (ArgumentException errArgument)
{
// The file wasn't a valid jpg file
lblOutput.Text = "The file wasn't a valid jpg file.";
System.IO.File.Delete(sSavePath + sFilename);
}
}
}
public bool ThumbnailCallback()
{
return false;
}
and read in this way

Assalam-0-Alaikum,
hru? well in .Net 2.0 there is a file upload control. put it on ur .aspx page. In code behind file
provide its id and press a dot(.). Now the real fun starts here.
--- to get file name :
dim fileName As String = FileUpload1.PostedFile.FileName
then u can use this string fileName to save it in the database using inLine Query or Stored Procedure etc. If u have Problem Inserting data in the database, do let me know. i would write u know how to do this.
-- to Save file in the specified Location:
FileUpload1.PostedFile.SaveAs("Location as string")
there are other properties and method for the fileupload control tht u could use but depend on the requirement.
Hope it Helps.
Regards.

hai i am using the file upload control indotnet as told by you.but here i want store the path of the image where it woulb stored not where it was stored.
accaording 2 ur soln it stores the the path of the image from where it upload the image...so can u solve it.
|

Assalam-0-alaikum,
yes i would tell u. look its u who will decide where to store the file. like,
fileupload1.postedfile.saveas("c:\myweb\images\image1.jpg")
now save the same path in the database i.e., c:\myweb\images\image1.jpg
now Question arises how to differentiate files. give them a unique name.
now how to give a unique name? there are so many ways but how do i save is, i create a folder with the username, save the file and name it with the username concatenated with some other patameters to make it unique.
hope u get it.
Regards.

Hi phuhoa
In ASPX, variable not stored in a long time. Just whene the page is created. To use long life variable use session (however in default just 20 minuites).
Like the example:
First, store your variable
Session("textbox1") = textbox1.text
To retrieve it
textbox2.text = Session("textbox1")
Hope it is usefull for you.

Hi Sandeep, Hi phuhoa
Query string is also a nice choice to "transfer" the variable. However, it is not really safe, when we deal with the security.
Let us follow the sample:
Me.TextBox1.Text = Request.QueryString.Get("prevpage").ToString
*Change the prevpage with the value of previous page.
