I thought that Page_Load events executed every time a page was loaded not just the first time. Am I wrong on this?
I have a Page_Load event that writes text to a label to display on the screen:
Output.Text &= "Welcome to my Website <br />" (Output being the ID of a Label control)
I also have an On_Click event for a button to display the same information:
Output.Text &= "Welcome to my Website <br />"
After clicking the button, I expected to see the output twice. Once for the page being reloaded and once for the click event. I thought that Page_Load events executed every time a page was loaded not just the first time.
I have the following PerformanceFactsheet.aspx.cs page class
public partial class PerformanceFactsheet : FactsheetBase protected void Page_Load(object sender, EventArgs e) // do stuff with the data extracted in FactsheetBase divPerformance.Controls.Add(this.Data); where FactsheetBase is defined as public class FactsheetBase : System.Web.UI.Page [code]...
I am using a Timer with a 3 minutes interval. I am exeuting the Page_Load event every 3 minutes. I am doing that this way as I have all this code inside an UpdatePanel1 which causes
a partial unnoticed postback to the server. I have a lot of code in the Page_Load event that I havenīt put here.
But what does not work is the code I have in the Page_Load event now.
I am trying to execute the javascript function with this line: body1.Attributes.Add("Onload", "startbk()");
This function should start an imageButton to change image between 2 images. This function do works if I refresh the page so the function itself do works.
But it seems this function does not execute when the Timer executes the Page_Load event, so this is my problem how I can solve this?
I am thinking this is a pretty simple problem... but I can not get it to function.I just want to get the calendar control to change a date which subsequently modifies a database select statement. I can get the current code to process without error, but the variable set is always a click earlier. Of course, I want the variable to be set upon any change in the calendar control.
public partial class NewBusinessReport : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) {
[code]...
Does this make sense? I just want it so that when SelectionChanged gets fired the Calendar1SelectCommandDate passes the correct date to the Page_Load page. The error I get now is:"The name 'Calendar1SelectCommandDate' does not exist in the current context"I get that the variable does not exist in the context. That actually seems to make sense based on what I have coded; however, I try to get that variable established and I still seem to be headed in the wrong direction.Basically, I have four calendar controls, one for a date (period 1 start, end and then period 2 start, end). I want to set the program so any change in that date sets off a new Select statement into the SQL server.
i wanted to know how i could add a user to a role when they enter a page, i would like to create a page that when anyone goes onto that page, the code will add them to a role, lets say for example role "SpecialMember"
So when anyone enters that page, they will be added to the "SpecialMember" role, Does anyone know how to do this?
I'm trying to change pageindex on page_Load event but its not working. I can change page by clicking links in the page after page loaded.If this info necessary GridView in UpdatePanel.
protected void Page_Load(object sender, EventArgs e) { /*...Some Codes...*/ //I'm trying to change page like this. GridView1.PageIndex = Index; GridViewPageEventArgs ea = new GridViewPageEventArgs(GridView1.PageIndex); GridView1_PageIndexChanging(sender, ea); } protected void GridView1_PageIndexChanging(object sender,GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; }
This should be an easy solution but I get stuck with it and hope I can get some advice/guidance from you:I have a simple aspx page with a Paypal button in it. The code shows in .aspx page:
I'm using ASP.NET 3.5 and C#.I load an SqlDataSource into a DataView on my Page_Load event. My SqlDataSource queries arandom record from the database. On my page I have an ImageButton, which when clicked uses a Response.Redirect("AnotherPage.aspx + "random id from database"). My problem is that when the button is clicked it fires the Page_Load event before the Response.Redirect takes place in the button_click event. This causes the current data(the users "id") that I had pulled from the database to be overwritten with new data(a different "id") from the database. So essentially the the page is redirecting to the 2nd random id that is queried from the db after the button is clicked and Page_Load is fired again, not the original id. Here's my code, hope it makes sense.Here's my Page_Load:
Can I put my dataview in another event or method so it's not called when a user clicks an ImageButton. Also I want the DataView to be repopulated on a postback/page refresh, just not on button clicks.
I have a GridView, here I am adding the LinkButtons at runtime to the GridView cells. I am also attacing an click event on these LinkButtons.
The issue is that when I populate the GridView from the Page_load the LinkButton click works, but if I move GridView polulation code in the Page_PreRender event the click event doesn't executes.
Code:
private void Page_PreRender(object sender, System.EventArgs e) { //does not fires the Click event of dynamically generated LinkButtons GridView1.DataSource = getDataTable();
I have a little question about building controls at runtime.
In my case I would like to create a checkboxlist in my page_load event
[Code]....
This control is a part of a wizard-Control. At the end after clicking the finisch-Button, the selected values have to sent by email to me. My question is, how can I get the ID of the Checkboxlist-Control whitch was build at runtime?I tried following workaround
[Code]....
But I get following error-message:
System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
I'm working on a web application using VB.NET. In page load event am calling a remote web service which take time to bring the data. During this process none of the other contents on page are shown(render).
I want to call this remote web service asynchronously so that other data of page is displayed and web service data will be displayed when its available.
Page_load event fires two time in firefox and the same page is working fine in IE. What might be the problem? If it is problem with Autoeventwireup then page_load event must fire two times in IE too. I believe it is not a issue of Autoeventwireup.
I have an aspx master/content page scenario. The parent page has an IFrame which points to a child.aspx. The child.aspx has a checkbox, On page_load of child.aspx, I want to show/hide the checkbox depending on the following logic:
- if the child.aspx is opened directly, then I have to show the checkbox.
- if the child.aspx is opened in the IFrame, then I have to hide the checkbox.
Basically, I want to check in child.aspx, if it contains a parent window then hide the checkbox control otherwise show it.I will prefer the show/hide code in codebehind in Page_load event as I have to execute some more logic depending on whether the it is opened from parent window or not.
<script language="javascript" type="text/javascript"> function DoesParentExists()[code].....
Using RegisterClientScriptBlock, I get error in JS. That the object hfDoesParentExist doesn't exist 'coz the control is not yet created. Right? I tried using RegisterStartupScript but in codebehind I always get null in hidden variable. I don't want to use the on button click or something like it. I need it on page_load event only.
I have a page which contains linkbuttons and panels. all panels have DetalilView and gridView controls. On click of linkbutton, panel's visibility is set. everything works fine on my local server. But on production server, no events of Button, DetailsView and GridView fires.
I have a dynamically created user control which is accomplished usingLoadControl().
When I debug, the LoadControl call is called once, however the Page_Load inside the user control is called twice. On each occasion, the postback property is false, so it seems somehow the Page_Load event is called outright 2 times and nothing to do with any postback?
I have a TreeView on a page which I will populate the nodes on demand and a checkbox, and they are in the same updatepanel. I can dynamically add new nodes to this treeview. But when I click the checkbox which will cause a postback, the TreeNodePopulate is called before the Page_load and it will regenerate the nodes that was added before. I was very confused how could this be happened. Is this related with PopulateOnDemand and Expanded priorities?
