iam trying to create image button in the pageload with clickevent dynamically but iam getting error. i have searched many blogs but i cant overcome with the problem.
'System.Web.UI.ImageClickEventArgs' does not contain a constructor that takes '1' arguments.
example shows how iam creating imagebutton in the pageload
ImageButton ib = new ImageButton();
Gridrow Button click loads aspx Page1 which is a Modal window(window.showmodaldialog). It has an ascx in it called UC1. In my Page1 following is added.
<head><base target ='_self'/></head>(this was added to solve the problem of losing session data on load of Page1) I cannot do away without this code.
I am assuming this is avoiding Pageload event of Page1 when the same gridrow button, who opens up Page1, is clicked the second time. Please note that after second click I can see the page1 with all it's controls but when I try to debug, I see that it does not raise the page load event the second time. It's as thought the page had been cached or the same frame is gettign loaded.
Problem is I want to raise the Page load event the second time also beacuse my dataload for Page1 happens only on page load. PS: Please note only the second click onwards page load doesn't happen. the first time pagelaod works. If I click a new row's button the first time it works.. later it stops doing a pageload

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 want to store 1st item.value of dropdownlist on page load.
but it is not allowing:
-The text property of the textbox has got the value you typed, despite viewstate false
-The checkbox.checked property is true, despite viewstate off
- And the selectedValue property of the dropdown is "", no matter what you chose. And to avoid obvious stuff, in fact putting a break point on the load method of the page, just before clicking the button would have shown the same thing...
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 RepliesI have got a graph with x number of datapoints, the data for the graph is coming from a stored procedure. I want to make the labels for the datapoints hyperlinks and I believe the best way to do this is with an ImageMap.
I am needing some advice/guidance in achieving this. I understand how to use the imagemap control, but I need some in how to add the hotspots on pageload.
I have a store procedure which will return the pixel coorinates of each datapoints on the graph, I just need some with the code and how to loop through each record and add a hotspot for it.

<%@ OutputCache Location="None" %>
to my aspx page. after adding this the page load event is getting fired in IE but not in firefox.
I have a bit of a problem with a DropDownList I am using. When the user changes the SelectedIndex, they get redirected to the same page, but with a query string on the end based on their selected value.
Because I'm not posting, and redirecting instead, the state of the dropdownbox is not saved, so it always defaults to the first one.But, if I save it in say a session, or set the selectedvalue according to the query string in Page_Load, when the user selects another listitem, the selection they have chosen is overridden by the selection delcared in Page_Load.
Can anybody tell me the description about
"#region PageLoad"
which i absorbed in a code given to me....
Based 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 a text box called txtName on my form.
In my page I know I need to place the code in my HEAD tag like so......
<script type='text/javascript' language="javascript">
document.FormName.txtName.value = "Robert";
</script> [code]...
But I cant seem to set a value to my textbox txtName with the above code......
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 an application where I currently are calling stored procedures, reading tables and filling GridView at PageLoad (If Not IsPostBack Then ...). The process takes some time and leaves the client waiting for this process to be completed even before showing the page.Now, is there a way where I can open the page, show a hour glass (or similar) and then automatically fill the gridviews? Is this where I should use threading (or backgroundworker) ?

View 3 RepliesHow 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

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?
