its because when postback occurs it removes javascript so to resolve this problem you require to register click event of the button again.

Hi,
I am working with the HTTP Post method to log the user into my framework. But when I run the page it does not redirect to the Page given in URL. What I am doing wrong?
Following is my code:
string strResponse;
string strPost;
protected void Page_Load(object sender, EventArgs e)
{
strPost = "txtUserName=abc&txtPassword=123";
UTF8Encoding objUTFEncode = new UTF8Encoding();
byte[] arrRequest = null;
Stream objStreamReq;
StreamReader objStreamRes;
HttpWebRequest objHttpRequest;
HttpWebResponse objHttpResponse;
Uri objUri = new Uri("http://www.mysite.com");
objHttpRequest = HttpWebRequest.Create(objUri) as HttpWebRequest;
objHttpRequest.KeepAlive = false;
objHttpRequest.Method = "POST";
objHttpRequest.ContentType = "application/x-www-form-urlencoded";
arrRequest = objUTFEncode.GetBytes(strPost);
objHttpRequest.ContentLength = arrRequest.Length;
objStreamReq = objHttpRequest.GetRequestStream();
objStreamReq.Write(arrRequest, 0, arrRequest.Length);
objStreamReq.Close();
CookieContainer cookieContainer = new CookieContainer();
objHttpRequest.CookieContainer = cookieContainer;
//Get response
objHttpResponse = objHttpRequest.GetResponse() as HttpWebResponse;
objStreamRes = new StreamReader(objHttpResponse.GetResponseStream(), Encoding.ASCII);
strResponse = objStreamRes.ReadToEnd();
objStreamRes.Close();
}
Thanks

First, you are not following the guidelines for posting here. Use the pre tags to format any code you post.
Of course it's not redirecting because you are not telling it to. All you are doing is writting, or attemtpting to, the content of the web request to the output stream of the same page. This is NOT the way to a redirect. Use Response.Redirect.
This is also not the way to authenticate users. I suggst you read up on forms based authentication.

hi,
I am trying to use user control event in the aspx page. I have two textboxes txt1 and txt2. txt1 is in user control(ascx) page and txt2 is in aspx page. Now with ascx page, i have one popup calender say calender1 too. Now when i click that calender1, both textboxes should show the selected date. How to do that? I can show the date in the textbox txt1 but how to do it for txt2?
thanks

If you are using JavaScript then get access to the textbox (document.getElementById(...)) and set the value.
If you using a postback then you need to expose an event on the user control that the main page can subscribe to so it can receive a notification to set the text.

can you give me some examples please ?? ok lets say there is a button btn1 in ascx page and textbox txtbox1 in aspx page. When i click the button btn1, txtbox1 should show "hello". so in this case, how to do it ?
suchita

|

in your user control add a property like... (I assume that your user control has text box called txt1)
private string displayText
public string DisplayText
{
get { return _displayText; }
set { txt1.Text = _displayText = value; }
}
now suppose your user control has name U1, then just add U1.DisplayText = "something" along with txt2.Text = "something" in your aspx page. and you are all set.
|
|
|
|
|
the above code is written in which page ?
suchita
|
|
|
|
|
but where to keep this code? aspx or ascx.. can you clarify it please ?? also i dont know where to define _displayText ??
suchita
|
|
|
|
|
ok the property (code block) you need to put inside your user control ascx.cs and the setting of the property (that U1.DisplayText = "something") should be inside your aspx.cs,
in other words you add a property in the user control to just pass on the value you assign to the text box inside the user control, and then when you want to set the value, you use the user control name . dispalytext to assign the value to the text box inside the user control.
|
|
|
|
|
so
you mean
In ascx page,you include the following code ?
private string displayText ;
public string DisplayText
{
get { return _displayText; }
set { txt1.Text = _displayText = value; }
}
and what about in aspx page ??
and where to define _displayText ??

yes just after the class declaration and before any method (not inside any method).
SayamiSuchi wrote: and what about in aspx page ??
here you define the value when you are assigning txt2.Text = "something"; assign your user control variable name i.e. usercontrol1.DisplayText = "something";
SayamiSuchi wrote: and where to define _displayText ??
that's typing mistake remove the _ (underscore from the code)

|

its so confusing?? Sorry i didnt get anything... can you clearly write down in steps.. that will be more helpful ?? where to keep which part ??

As i assume that you want textbox1 and textbox2 to get their values during an event in your usercontrol (ascx file), you have to follow Mark Nischalkes instructions.
For example:
In your ascx file, you can set the Text Property of your textbox1 control (which is inside the ascx) easily by using:
TextBox1.Text = "xy";
This is pretty simple. In addition, you want to set the text of another TextBox (Textbox2)- which lives inside the aspx Page. This is more complex.
You have to define an event/delegate in your .ascx file (usercontrol), which is subscribed by your page class (.aspx.cs) during page load and called when you set the textbox1.text property.
This is the server-side solution. Another possibility would be to use javascript.
I'm posting some example code now, which is not a 100% answer to your question, but it should help you out. I cannot modify this code more due to time restrictions:
Define this delegate (maybe in a seperate file somewhere in your
usercontrols namespace):
public delegate void OnSelectDelegate(string text);
In your Usercontrol:
public partial class MyUserControl: ....
{
public OnSelectDelegate OnSelect;
private void SetText(string text)
{
TextBox1.Text = text;
if (OnSelect != null)
OnSelect(text);
}
}
In your aspx Page during page-load:
this.MyUserControl1.OnSelect += new SomeNameSpace.OnSelectDelegate(OnSelect);
Include this method in your aspx:
private void OnSelect(string text)
{
TextBox2.Text = text;
}
Hope i didnt include too many typing mistakes and this helps a bit.
Good Luck

hey
this.MyUserControl1.OnSelect += new SomeNameSpace.OnSelectDelegate(OnSelect);
hey here MyUserControl1 is the ascx class name or one of the control in ascx file ?

I think at this point you should give up and hand over the project to someone else. If this confuses you, you are most certainly over your head.

mmm! hard to understanding?
let's say that you have an ascx page name Logo.ascx.
Then when you add this ascx to a page named Test.aspx, your ascx User Control is named with ID="Logo1" in the Logo.ascx.cs add this:
public string txt;
private string Text
{
get { return txt; }
set { txt = value; TextBox1.Text = value; }
}
and now you can call the public property of the ascx file! use this in Test.aspx or any page you've added the User Control
protected void Page_Load(object sender, EventArgs e)
{
Logo1.txt = "my text";
TextBox2_GetText.Text = Logo1.txt;
}
 good luck

Good luck indeed if anyone uses this 
First, never expose a public variable, use proprties to expose them. Otherwise you have no way to validate and control access.
PunkIsNotDead wrote: TextBox1.Text = value;
This is completely backward and unecessary.
You have missed the OP's original request and intent and have added nothing but confusion to the subject.
