Do you include any Javascript files in the page?
Does debugging give any clue to where the error might be?

I have a LoginControl.ascx control and a ListItems.aspx page. Thay are placed in a MasterPage.master.
I want the login control to be able to handle manual login as well automatic login from reading a cookie.
Depening on the login result the list will display different set's of items.
My problem is that when starting the ListItems.aspx the order of page load is:
1. ListItems_PageLoad (displaying a list of item based on NOT logged in state)
2. Master_PageLoad
3. LoginControl_PageLoad (automatically logging in the user)
This means that the list is displayed on the NOT logged in state and I have to refresh the page to get the correct list.
If I click logout in the logincontrol the list is rendered in the same way:
1. ListItems_PageLoad (displaying a list of item based on LOGGED IN state)
2. Master_PageLoad
3. LoginControl_PageLoad (logout the user)
How should I go about programming to get the result I want?
1. ListItems_PageLoad (Initalize the login procedure)
2. Master_PageLoad
3. LoginControl_PageLoad (loggin out the user)
4. ListItems_PageLoad (complete the load, displaying a list of item based on LOGGED IN state)
What am I missing?

Use the Prerender event for some of this ( and if you're in .NET 2.0, there are even more events to choose from ), which will allow you to control the order. That is, the Page_load happens before the prerender, so putting something in the prerender, will force it to run later.

Thanx for the reply, I think you pointed me in the right direction. I found this article from Vivek Thakur.
http://www.codeproject.com/useritems/lifecycle.asp[^]
From where the page life-cycle-summary is:
1. OnPreInit<br />
2. OnInit<br />
3. (LoadViewState) ONLY ON POSTBACK<br />
4. (LoadPostBackData) ONLY ON POSTBACK<br />
5. Page_Load<br />
6. (recusive Page_Load's for masterpages, other pages, controls)<br />
7. Control Event Handlers (like Button1_Click()) <br />
8. PreRender<br />
9. (recusive PreRender's for mas...)<br />
10. SaveViewState<br />
11. Render<br />
12. (recusive Render's for mas...)<br />
13. Unload
...and from what I can gather, if dependent of the state of user controls placed in a masterpage, I should put the code in prerender as you said. How come all beginner tutorials are so focused on Page_Load then?

Because the stupid IDE generates page load and not page prerender methods. The most important thing to understand is that all events happen after load and before prerender, that's another reason that all rendering steps should take place in prerender, so they reflect the results of any events.

if i took web part on mmy page error occured regarding sql server
but whole application runs on another pc without any error having same sql server configuration
|
|

|

More details about the errorcode would be helpful, you may need to update the Web.Config file to show the complete error message, look at the customError section for more details, if you can post the more detailed information then maybe I can help..

Check the sql server connectivity. see machine.config for more details on connectionstring which is used for webparts

hi all,
i am creating a page in asp.net using c#.To insert the data,i just wrote the sql command for inserting and followed the same for edit and update.
for example..
string myinsertQuery = "insert into DriveUnits(SerialNumber,CorporationID,CorporationDivisionID,HWVersion,DateManufactured) values('" + SrNumber_TBox.Text + "','" + Session["corporationid"] + "','" + CorporationDivisionID + "','" + Hwversion_Tbox.Text + "','" + DateMFD_TBox.Text + "')";<br />
SqlCommand myCommand_insert = new SqlCommand(myinsertQuery);<br />
myCommand_insert.Connection = myConnection;<br />
myCommand_insert.ExecuteNonQuery();<br />
myCommand_insert.Connection.Close();
but instead of writing code in cs file,i just want to call a class
so that wherever we need to insert data,we can just call the class and the functions defined.
i created a class and a function and pass parameters.but it is showin invalid arguments..
plz give ur suggestions on creating a class and its functions.
Thanks in advance,
cheers

not sure i got you..
maybe this is what you want..
Using static method.
public class MyDBMgmt{
public static bool ExecuteSQL(string cmdText)
{
return true;
}
}

Is this ASP.NET 1.0, 1.1, or 2.0 ? What errors are you getting ? You should certainly put all your SQL in a class, so that it's in a seperate layer to the rest of your app, and can be reused as needed.

Hi all
i have some code above. I have Some problem when i save this image is type Gif/ JPG so this image show but when i save is PNG is not yet And when i check C:\\demo.Png is Exist and open is ok but on web is not ok. ????
byte[] byImg = objimg.getBytes();
using (MemoryStream objStream = new MemoryStream(byImg))
{
System.Drawing.Image img = System.Drawing.Image.FromStream(objStream);
Bitmap bp = (Bitmap)img;
//Check this image can show
bp.Save("C:\\demo.Png", System.Drawing.Imaging.ImageFormat.Png);
// Show image
bp.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Png);
}
|

Problem is the format of PNG is not compatible with the Response.OutputStream method directly, you need to store the image in a memorystream at then send that to the browser...
System.IO.MemoryStream memStream;
byte[] bytBuffer;
Response.Clear();
Response.ContentType = "image/png";
memStream = new System.IO.MemoryStream();
bp.Save(memStream, System.Drawing.Imaging.ImageFormat.Png);
bytBuffer = memStream.ToArray();
Response.OutputStream.Write(bytBuffer, 0, bytBuffer.Length);
Response.End();
My C++ skills not good, this is a translation of the VB.NET code that I use..

Use cookies for this kind of problem. Save the user name in cookie on login.aspx on successfull login then redirect. And onload event of login.aspx retrieve the value from cookie

You could store the username in a session variable and then display that information..
<%=Session("Username")%>

Developing a simple service request form with in an intranet...and I need the form to identify the user and automatically fill in the Sent From field when the user submits a request via email from a asp.net 2.0 webform. Please guide me in the right direction.
Thank you.

Need more information,
1) Do you have a source for the email information available
2) Does each user have a unique identification
With this information it may be possible to find a solution.

|
|
|
Their login ID should be unique identifier and email address is provided by exchange server.

Can you look at the event log ? Is there any error related to W3C service or IIS?
|
|
|
|
|
Also did you enable Windows Authentication for the website?
|
|
|
|
|
Windows Authentication was enabled on the IIS.
This has not solve the problem.
Can i develop my asp.net pages using the File System instead of IIS when done, now create a virtul directory from IIS. I dont know whether this approach has any drawbacks
pls anyone with a solution should help
