View 1 RepliesOn my page I have a calendar. The idea being that the user clicks the date, which runs a query to update a gridview to list things happening on that day. Everything there works fine.However, I want it to run on the Page_Load to automatically display today's events at start up. It refuses and will only update the gridView if I actually click on the calendar.in my Page_Load I have the following code :
if (!IsPostBack)
{
... other code... [code]...
Is my code in the wrong place? Are there events I don't know about. Fairly new to this asp.net business. Any light please shine it here.
I have a grid view,with last column a template field with a button.

I'm making a call to a web service which returns some data I want to disply in a gridview.The data returned contains two columns "UseDate" & "Quantity" I need to sort the grid by UseDate on pageLoad...I can only make a call once every 120 seconds to return the data.
How can I get the GridView to sort?I have tried couple things but either it does nothing or I get an error... that the Grid fired an unhandled event.

i'm creating and adding checkbox in my code behind to a parent control.
autopost back is true, it's posting back on being checked, but i'm not sure how to capture the fact that it's checked before I recreate/add it to the parent control again.
i can search all controls and find it prior to re adding it to the parent, but it never shows checked...
i have a checkchanged event on it that never fires, thing it's a flow/view state issue, but not sure how to reslove...
I have a masterPage on that i am using AjaxModalPopup for login purpose.My requirement is when i login via Master page then it should show the Logged-in User details on the current Content Page that is using same master page.
Here i am using following code to get it back to the same content page after succesful login but it does not show the user details on the same content page rather when i go to next page then it appears.
if (Session["SignedIn"] == null)
{
ValidateUser();
ModalPopupExtenderMaster1.Hide();
string currentPageUrl = System.IO.Path.GetFileName(Request.Url.AbsolutePath);
Server.Transfer(currentPageUrl);
}
But it does not gives user-details on the same content page.
I can't figure out why, but before my form is even displayed, the CheckChanged event fires. I don't even have a chance to check anything. Has anyone seen anything like this?

How to display record in gridview using pageload event in vb.net ? i wanna use two SqlDatasource1 and sqldatasource 2 to display record in single gridview1
SqlDatasource1 will display all records from tabel where as SqlDatasource will be used to display particuar record search in table 1 but how to do this ?
I have used an Update Panel, and place two RadioButtons in Update Panel.
Radiobutton1 ID="radio1" and RadioButton2 ID="radio2"
Then I have set AsynPostBack for Both radioButton's.
Now, on Page Loads radio1 will triggered and fetch all data from Database, then when I click on radio2 it will triger and fetch all data, but if I again click radio1 It doesn't get trigger.
Same process I have done by setting PostBack on both Radiobutton's but show's same result.
Is it possible to use PageLoad as a method? I want to load the page in some button clicks, and Page_Load(); doesn't work (the page doesn't load).
View 2 RepliesBased on this piece of code, I want to do exactly like this demonstration. However, correct me if I'm wrong but if two or more users somehow simultaneously access the web page at the same precise nanosecond in time, then wouldn't we have a race condition? So is this piece of code valid? How would I correct this to make it thread safe?

I have actually resolved my problem but I want to understand why. The scenario I have is an input for logging in on my Default.aspx page. When the user logs in the page refreshes and the login box changes to display a logout box using:
loginBox.visible = false
logoutBox.visible = true
My question is about the positioning of this code. I had my code validate the users input when the btnLogin is clicked. I then had those two lines above under PageLoad but this did not work. The user would log in but would have to refresh the page to update the boxes. Instead I had to place those two lines of code in the btnLogin Clicked area, at the same time as the user is validated.
It was always my understanding that when something on the page is clicked/activated the entire page is reloaded, but this appears not to be the case otherwise the PageLoad area should have worked.
i have the following two asp.net pages the default contains two textboxes and a button the second contains textbox with a button i saved the value of the textbox in the seconed page in session["1"] when click the button in this page it will redirect you to default in the default page on pageload events i have check the values of the session if one it will appear in textbox 1 if it tow it will appear in the textbox 2 but i lose the old values of the textbox when another get filled please tell me how to keep this values after it filled and the page load ,the session get the value to fill the other textbox her is the code: defualt protected void Page_Load(object sender, EventArgs e) { if (Session["1"]!=null) { switch (Session["1"].ToString()) { case "1": TextBox1.Text = Session["1"].ToString(); break; case "2": TextBox2.Text = Session["1"].ToString(); break; default: break; } } } protected void Button1_Click(object sender, EventArgs e) { Response.Redirect("WebForm1.aspx"); } webform1 protected void Button1_Click(object sender, EventArgs e) { Session["1"] = TextBox1.Text; Response.Redirect("Default.aspx"); }
View 2 RepliesI need the ability to check a box and then store or remove the text of the checkbox clicked to my sql server database. see my code below that is written in vb.
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="SBN_Company_Cat_Types.aspx.vb" Inherits="ShopBuyName_Test_Site.SBN_Company_Cat_Types" %>

I want to know how can I go about disabling textboxes upon pageload?
I will have to loop thru all the controls on the page in order to accomplish this.
I am using C# 2008 asp.net 3.5
I'm creating a forum and the forum posts are items in a datalist.
Now I want to include the nifty feature that when one has replied to a message and the forum thread page is being displayed, the page is autmatically scrolled down to the message one wrote (the same thing goes for linking to a message, one wants the page to be scrolled down to the right place from the start).
I guess this could be done using anchors an html, but is there a function i vb.net that would do this for me?
On page load I have this:
LinkButton1.Attributes.Add("onclick", "window.open('EditClients.aspx','','height=700,width=600');return false")
I also have an event handler for LinkButton1:
Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click
Label8.Visible = True
RefreshButton.Visible = True
End Sub
The problem is the event handler is ignored. Label8 and RefreshButton do not becoem visible when clicking Linkbutton1, but the new window opens fine. How can I make all things happen?
Why is it that the aspx.net system fires all the TextChanged event (for a slider) to a value of 0, when you did not originally set any values?
What I notice happening is, if you do not declare a Slider1.Text = "0" value initially, then when the page_load fires, the control protected void Slider1_TextChanged is fired automatically.
Whats the diffrence between pageload and page postback in asp.net
how it affect on page life cycle.
