Validation Didn't Happen On 2nd Time Around?
Jan 18, 2010
I have a Page_load sub with the following:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Request.ServerVariables("SERVER_PORT") = 80 Then
Dim strSecureURL As String
[code]....
The validation load in this page worked on the first click of btnDonation, if I don't change anything and click the btnDonation again, it automatically go to my confirm page. Instead, I want it to continue to check for requiredFieldsOK(). Note that if I fill in one of the missing required fields, the validation will work.
My question is: How can I continue to check for requiredFieldsOK() even if user didn't fill out any additional information?

I read these words in a book:
Projectless development simplifies debugging: When creating a web project, you must recompile the entire application when you change a single page. With projectless development, each page is compiled separately, and the page is only compiled when you request it for the first time.
How does compiling happen only for the first time in projectless development?
Should it recompile every time I run the page to reflect the new code I wrote it?

I'm trying to use required validation controls on two text boxes and tried using the following code:
<asp:TextBox ID="starttimeInput" runat="server" Width="130px" Height="23px"></asp:TextBox>
<span class="style1">*</span> Start Time <asp:RequiredFieldValidator ValidationExpression="^([1-9]|1[0-2]|0[1-9]){1}(:[0-5][0-9][aApP][mM]){1}$"
ID="StartTimeValidator" runat="server"
ErrorMessage="You Must Supply Both a Start and an End Time"
ControlToValidate="starttimeInput"></asp:RequiredFieldValidator>
but I can still enter whatever I want into the text box. What I'm trying to check for is that users are entering a time in a valid format.

My code below has a drawback. The scenario is this, i have two user roles - Approvers and Encoders. The encoders are not allowed to view the price only the approvers. Using the code below, i can now hide the Price column. but the problem is, when the encoder modified the quantity column, the Total Amount (Quantity * Price ) is zero. Giving zero value for price. When the approvers view the transaction,the Total Amount is zero. Is that really the possible thing to happen when hiding a datafield?
HTML Code:
For Each colField As DataControlField In colFields
If TypeOf colField Is BoundField Then
Dim bField As BoundField
bField = CType(colField, BoundField)
If bField.DataField = "ReceivPrice" Then
bField.Visible = False ' Hide Price Column
End If
End If
Next

VWD 2008 Express. Visual Basic.
I have two validationsummary controls on my page for aesthetic reasons. Each control is assigned a validation group (StudentInfo and Grades). validation controls in the upper part of my page are in validationgroup StudentInfo and those in the bottom part of my page are in validationgroup Grades.
However, I only have one "Save" button control that causes validation. I want the Save button to validate both groups of controls, but it appears to only allow one Validation group to be specified in its properties.
Is there a way to have a button cause validation for both groups?

I am having two text box for "Password" and "confirm password".
The password should be minimum of 6 charecters.
when the password is minimum of 6 charecter it shows a error message and when the confirm password and password is not matching it shows the error message.
It displays both the error message at a time.
Is there is way to display one by one.
I am using following regular expression validater to validate for minimum of 6 charecter
" <asp:RegularExpressionValidator ValidationGroup="vgProductDetails" ValidationExpression="^([a-zA-Z0-9]{6,10})$" ErrorMessage="Password Should be minimum of 6 Characters and maximum of 8 characters." SetFocusOnError="true" ControlToValidate="txtPassword" ID="RegularExpressionValidator4" runat="server"></asp:RegularExpressionValidator>"
For comapring the password and confirm password, i am using the following.
"<asp:CompareValidator SetFocusOnError="true" ID="CompareValidator2" runat="server" ControlToValidate="txtconfirmPassword" ControlToCompare="txtPassword" ErrorMessage="Password and confirm password should be same."></asp:CompareValidator>"

What's the best way to handle exceptions that happen from within a controller's constructor?
All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory.
Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky.
If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve.

I have an application that I need the user to enter in a date and time: 10/16/2010 1:00:00 PM How can I setup validation to check to make sure the user has entered in the date/time in that manner? I can use the validators in asp.net to check for date and even when I create a custom validator I don't know how to tell if the user has entered the data correctly. I am adding this functionality to an existing system. So I can't change the text box into two fields for validation.

ow can I display multiple validation summaries at one time? I currently have three different validation groups on a page for different sections of the page. Basically, the first section should be validated by one validation group, the second section should validate both the the first and section section and the third should validate all three.I've got the following javascript which validates properly, but only the last validation summary is visible, the first two don't appear (but the red asterisks next to the controls do appear).
function ValidateSection3() {
var validated = Page_ClientValidate("vgSection1");
if (validated) {

I want my Start Time and End TIme should not be equal to each other and I want the End TIme should not go beyond the Start TIme. For example:
Start Time = 8:30 AM
End Time = 8:00 AM
The above example should have an error because the End Time go beyond the Start Time.
My HTML code:
Time In:
<cc1:MaskedEditValidator ID="mevStartTime" runat="server" ControlExtender="meeStartTime"
ControlToValidate="txtStartTime" IsValidEmpty="False" EmptyValueMessage="Time is required "
InvalidValueMessage="Time is invalid" Display="Dynamic" EmptyValueBlurredText="Time is required "
InvalidValueBlurredMessage="Invalid Time" ValidationGroup="MKE" ForeColor="Red" />
<asp:TextBox ID="txtStartTime" runat="server" Text='<%# Bind("StartTime", "{0:t}") %>'
[Code] ...
Time Out:
<cc1:MaskedEditValidator ID="MaskedEditValidator1" runat="server" ControlExtender="meeStartTime"
ControlToValidate="txtEndTime" IsValidEmpty="False" EmptyValueMessage="Time is required "
InvalidValueMessage="Time is invalid" Display="Dynamic" EmptyValueBlurredText="Time is required "
InvalidValueBlurredMessage="Invalid Time" ValidationGroup="MKE" ForeColor="Red" />
<asp:TextBox ID="txtEndTime" runat="server" Text='<%# Bind("StartTime", "{0:t}") %>'

This thing has just came to my head and I wanna share it.Note : I could easily test it but I am being lazy here to see if anybody has ever experienced something like that before.Let's assume that I have a web site which built-in membership structure of asp.net has been implemented on. What will happen to asp.net membership if the client browser blocks cookies? Does framework throw an exception when a user tries to log in or do something else?

I have a Wizard which has a FileUpload in one of the steps. It also has an "Upload" button. When the user browses to a file, and clicks Upload, I upload the file into SQL.
There seems to be some synchronization problem for very large files, and I would like to disable the Wizard's Next button until the Upload of the file to SQL completes. It can take a while, especially on a wireless PC.
In my OnClick event for the Upload button, I am trying to disable the Next button. The code, which is below, appears to be correct, but the Next button doesn't actually disable until the Query completes. Can I get the Next button to disable immediately instead of after the SQL Update completes?
Here is my code:
Protected Sub JustificationDocUploadButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles JustificationDocUploadButton.Click
If RequestJustificationAttachment_FileUpload.HasFile Then
Dim obj As Object = Wizard1.FindControl("StepNavigationTemplateContainerID")
Dim startButton As Button = obj.FindControl("StepNextButton")
startButton.Enabled = False
SqlDataSourceJustificationAttachment.Update()
End If
End Sub

I have a form that uses group validation with the following on btnDonation_Click. However, when I click btnDonation, the page comes back to itself even if everything is valid. Then, I click btnDonation again without changing anything, this is when the page will postback to Confirm.aspx. Do you know what might have caused it?
Code:
Protected Sub btnDonation_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDonation.Click
Page.Validate("GiftValidate")
If (rbContribType.SelectedIndex = 0 Or cbPrefHAddress.Checked = True) Then
Page.Validate("HAddressValidate")
ElseIf (rbContribType.SelectedIndex = 1 Or rbContribType.SelectedIndex = 2 Or cbPrefOrgAddress.Checked = True) Then
Page.Validate("OrgAddressValidate")
End If
If Page.IsValid Then
btnDonation.PostBackUrl = "~/Confirm.aspx"
End If
End Sub

I've run across with client-side validation. Firstly I'm assuming that everything is set up properly because client validation is working fine other than this specific scenario. The scenario is that if I have a field with a validation attribute on it then I can clear th field value and client validation won't flag it as an error even though the validation should fail. If, however, I type in something that is invalid then from then on it works correctly. It seems like client validation is missing the clearing of the field if it has not yet generated a validation error. Here's a simple model to demo the issue:
[Code]....
Now assume that I have this as my model instance: new SimpleModel() { Id = 1, Name = "One1", EventTime = DateTime.Now } The model is valid. Now I drop in an edit form generated by the Add View dialog. Again I'm assuming client validation is properly set up because it works except for the very specific scenario given earlier.........................

I have a Custom Repeater control that inherits from Repeater and has paging functionality, however when I click the next page button the first time it refreshes the control but does not change the page, if I click it again after that it changes page perfectly. I know what the issue is, when I click the next button it does a postback, then the data is bound to the repeater, and then after that the NextButton Event is handled.
Is there any way I can change the order of the page load events?? Or force the repeater to reload again after the event is handled?? I've included my Custom Repeater class bellow:
using System.Web.UI.WebControls;
using System.Web.UI;
using System.Data;
using System.Collections;
using System;
namespace ASPresentation.Controls
{
[ToolboxData("<cc:PagedRepeater runat=server></cc:PagedRepeater>")]
public class PagedRepeater : Repeater
{
public int PageSize { get; set; }
public int CurrentPageIndex
{
get
{
return Convert.ToInt16(Page.Session["ProjectIndex"]);
}
set
{
Page.Session.Add("ProjectIndex", value);
}
}
public PagedDataSource pagedData = new PagedDataSource();
LinkButton NextBtn = new LinkButton();
LinkButton PrevBtn = new LinkButton();
public bool IsLastPage
{
get
{
return pagedData.IsLastPage;
}
}
public bool IsFirstPage
{
get
{
return pagedData.IsFirstPage;
}
}
public override object DataSource
{
get
{
return base.DataSource;
}
set
{
pagedData.DataSource = (IEnumerable)value;
}
}
protected void NextButtonClick(object sender, EventArgs e)
{
if (!IsLastPage)
{
CurrentPageIndex++;
}
}
protected void PrevButtonClick(object sender, EventArgs e)
{
if (!IsFirstPage)
{
CurrentPageIndex--;
}
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
NextBtn.Text = "Next";
PrevBtn.Text = "Prev";
NextBtn.Click += new EventHandler(NextButtonClick);
PrevBtn.Click += new EventHandler(PrevButtonClick);
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
base.Controls.Add(PrevBtn);
base.Controls.Add(NextBtn);
}
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
}
public override void DataBind()
{
pagedData.AllowPaging = true;
pagedData.PageSize = PageSize;
pagedData.CurrentPageIndex = CurrentPageIndex;
base.DataSource = pagedData;
base.DataBind();
}
}
}
