Iam passing a parameter in response.redirect,But the value is not getting on the target page
Login.aspx.cs
protected void Button1_Click(Object sender,
System.EventArgs e)
{
string umasterid = drow["UserMasterId"].ToString();
Response.Redirect("Default.aspx?Name=" + umasterid );
}
Default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
string Name = Request.QueryString["Name"];//value not getting here
}
what went wrong for me???
Try following:
Login.aspx
protected void Button1_Click(Object sender,System.EventArgs e)
{
Response.Redirect("Default.aspx?Name=umasterid");
}
Default.aspx
protected void Page_Load(object sender, EventArgs e)
{
Response.Write(Request.QueryString["Name"]);
}

Properties window asp.net: Just like other controls have that thunderbolt icon, when you select the entire form itself, I don't see a thunderbolt for the page level events.
When you double click on the form, Load is created for you.
But there are other page level events, and I expected to see them and define them, through properties window.
But for the form itself, there is none. See screenshot.
Is this by design? Or am I experiencing an anomaly?
My guess is that maybe the event recognized by the web page through the name of the method itself (Like page load is always Page_Load, etc.)
Click here for screenshot...No Thunderbolt:
Yes, I think this is by design. Only certain event names are recognized.
You can type this in, and it will recognize these event names and do accordingly:
protected void Page_PreInit(object sender, EventArgs e)
{ Response.Write("Page_PreInit" + "<br/>"); }
protected void Page_Init(object sender, EventArgs e)
{ Response.Write("Page_Init" + "<br/>"); }
protected void Page_InitComplete(object sender, EventArgs e)
{ Response.Write("Page_InitComplete" + "<br/>"); }
protected void Page_PreLoad(object sender, EventArgs e)
{ Response.Write("Page_PreLoad" + "<br/>"); }
protected void Page_LoadComplete(object sender, EventArgs e)
{ Response.Write("Page_LoadComplete" + "<br/>"); }
protected void Page_PreRender(object sender, EventArgs e)
{ Response.Write("Page_PreRender" + "<br/>"); }
protected void Page_PreRenderComplete(object sender, EventArgs e)
{ Response.Write("Page_PreRenderComplete" + "<br/>"); }
protected void Page_Unload(object sender, EventArgs e)
{
//Response.Write("Page_Unload" + "<br/>");
}
I try to call google voice.
Here is my code:
public partial class _Default : Page
{
const string apiString = "http://translate.google.com/translate_ttsie=UTF-8&q={0}&tl{1}";
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = "en";
WindowsMediaPlayer p = new WindowsMediaPlayer();
p.settings.volume = 100;
p.URL=string.Format(apiString,System.Net.WebUtility.UrlEncode(TextBox1.Text),Label1.Text);
}
It does not read the text. What to do?
Here is my code and i want to call the my custom method (Application_My()) automatically when application is loaded/refresh every time like Application_OnEndRequest().
Thanks in advance.
<%# Application Language="C#" %>
<script runat="server">
// THis code will be executed automatically when page is reloaded everytime
/*protected void Application_OnEndRequest()
{
Response.Write("Thsi page is executed on=" + DateTime.Now.ToString());
}*/
// how to call below method automatically when page is reloaded everytime
//such as above
protected void Application_My()
{
Response.Write("Hi welcome");
}
protected void Application_Start(object sender, EventArgs e)
{
}
protected void Session_Start(object sender, EventArgs e)
{
}
protected void Application_BeginRequest(object sender, EventArgs e)
{
}
protected void Application_AuthenticateRequest(object sender, EventArgs e)
{
}
protected void Application_Error(object sender, EventArgs e)
{
}
protected void Session_End(object sender, EventArgs e)
{
}
protected void Application_End(object sender, EventArgs e)
{
}
protected void Application_EndRequest(object sender, EventArgs e)
{
Application_My();
}
However, note that this is called for everything that is managed by your aspnet pipeline, so you might get called on css and image requests.
You could add Debug.WriteLine(Request.Url); to the code above to see what happens when you enter your site.
I have this:
protected void Page_Load(object sender, EventArgs e)
{
nome_Txt.Text = Profile.dados_pessoais.nome;
}
protected void save_Click(object sender, EventArgs e)
{
Profile.dados_pessoais.nome = nome_Txt.Text;
}
If Profile.dados_pessoais.nome is empty, nome_txt.Text is empty too. When I change nome_Txt.Text to teste for example, when I click on the button nome_Txt.Text is empty.
What am I doing wrong?
The Page_Load event run before the button click event so you always assign the text box to empty value.
To solve this, don't populate the textbox when you are in a Postback:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
nome_Txt.Text = Profile.dados_pessoais.nome;
}
}
As also stated in a comment, you probably have to save the profile after changing it otherwise it won't be saved when you next load the page:
protected void save_Click(object sender, EventArgs e)
{
Profile.dados_pessoais.nome = nome_Txt.Text;
Profile.Save()
}
This is what I'm trying:
public partial class _Default : System.Web.UI.Page
{
String test = "hi ";
protected void Page_Load(object sender, EventArgs e)
{
test = test + test;
Button1.Value = test;
}
protected void Button2_Click(object sender, EventArgs e)
{
Button1.Value = "u're trolled !";
}
protected void Button1_Click(object sender, EventArgs e)
{
}
}
when the page is first loaded it shows "hi hi " as the Button1's value. But whenever I click Button2, it shows "u're trolled !" as Button1's value. My question is if the page is postback every time I click the button and the Page_Load is called, then why does it shows "u're trolled !" instead of appending "hi" ?? Isn't the Page_Load called every time the page reloads ?
Use this code to know which value come when :
String test = "hi ";
protected void Page_Load(object sender, EventArgs e)
{
test = test + test;
Button1.Value += test;
}
protected void Button2_Click(object sender, EventArgs e)
{
Button1.Value += "u're trolled !";
}
protected void Button1_Click(object sender, EventArgs e)
{
}
You need to understand the ASP.NET Page Life Cycle, as Code addict said its the sequence of events that causing the issue for you.
