Oct 12, 2010
I have a vacation booking page and don't want customers to go directly to the booking page. (course in that case customers could enter there own dates or leave the dates blank)Is there a way that if a user enters
www.mysite.com/booking.aspx into there browser it redirects to an error page.But the page must be visible after filling in arrival and disparture dates on a parent page. So to simplify: Can I check on opening booking.aspx if the sender is calendar.aspx then open booking.aspx else goto error page

I have one login page which contains popup control for entering login details. When user successfully logged in then Itemlist page will get open and login page also remains open (as per my requirement) with some text. Now if user reloads the login page then it will open second Itemlist page though first Itemlist page is opened. So i want to check on login page that if Itemlist page is already open then it doesn't open second itemlist page.

I have a gridview control sitting in a jQuery Accordian. The data in the grid diplays fine, however in IE 6 the page numbers do not display when the pane of the accordian is first opened. If you open another pane and then re-open the pane containing the grid view the number appear. There is also no issue with IE7 or later or FF.

I have a page with a gridview on it. The gridview can not be seen when the page is opened. There is a dropdownlist and a button on the page. The user is supposed to make a selection in the dropdown and then click the button (labeled "Go") and then the gridview appears. The problem is that the gridview appears in response to the dropdown selection, before the go button is clicked. I'm sure this is easy but how can I stop the gridview from appearing in response to a dropdown selection? The dropdown is called ddlfilter. This is the code I am using:
Part 1 (continued in next post):
Code:
<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"[URL]>
<script runat="server">
Private Function GetColumnIndexByName(row As GridViewRow, SearchColumnName As String) As Integer
Dim columnIndex As Integer = 0
For Each cell As DataControlFieldCell In row.Cells
If TypeOf cell.ContainingField Is BoundField Then
If DirectCast(cell.ContainingField, BoundField).DataField.Equals(SearchColumnName) Then
Exit For
End If
End If
columnIndex += 1
Next
Return columnIndex
End Function
Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
If Page.IsPostBack() Then
If ddlFilter.SelectedItem.Text.ToString() <> "- ALL -" Then
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Cells(GetColumnIndexByName(e.Row, ddlFilter.SelectedItem.Text.ToString())).CssClass = "viscol"
End If............

I have a site which has restricted access. Access is controlled via session variables.
There are a lot of pages to the site so I was going to check for the session variable via the page load event in my mater page. However, on certain pages I use the session variable in that pages page load event. This throws an error when the session doesn't exist, but what I want is the master page's page load to fire first.

Searched and couldn't find anything. I'm wrtiting an intranet application, and it creates links to see the original PO or Order for a given order number. Problem is that some of these orders were never put into the system electronically, so you get an error 400, no such page. Is there some way to programatically 'test' a link before sending the user to this error message?

I have an application that posts to a form on a different page, on a different site. Everything works fine unless the user presses the back button.The way it'ssetup now, if th euser forgets their pin, they click alink which takes them to a popup window. The enter their info and then they're sent a new pin. Fine.However, I'm trying to account for all possible scenarios. What if the user forgets their pin, is taken to this other page, and then decides they remembered their pina nd presses the back button. They'll need to reload in order to be able to try to post again, otherwise the session variables I'm using to log them in won't reset (I reset some in the page load event).Is there anyway to detect whether the page was arrived at via the browser back button so that I can reload it?

I have a function that loops through the control on my page to set attributes. This works fine, except that I only want the attributes to bet set on the controls on the content page, and not on the master page. Is it possible to check where the control resides? Or to only loop through controls on the content page?

An error occur something like this "Page.IsValid cannot be called before validation has taken place. It should be queried in the event handler for a control that has CausesValidation=True and initiated the postback, or after a call to Page.Validate. I make some work around but it didn't work
Here's my code in my Page Load event that an error occur
Code:
if (Request.QueryString["id"] != null)
{
txtID.Text = clsFunction.ReplaceString(Request.QueryString["id"].ToString());
if (!Page.IsValid)
{
Page.Validate();
cmdProceed_Click(sender, e);
}
}
In my page, I have this two validation group so if I am going to re-structure my above code like this
Code:
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["id"] != null)
{
txtID.Text = clsFunction.ReplaceString(Request.QueryString["id"].ToString());
Page.Validate();
if (Page.IsValid)
{
cmdProceed_Click(sender, e);
}
}
}
I will not encounter the above mentioned error however, my second validation group trigger and the cmdProceed_Click is not executed.
