In my .aspx page which derives from a master page I have a contact form which uses some validation, such as the RequiredFieldValidator and RegularExpressValidator.At top of my page I have a link bar and whenver I am at contact.aspx I can't navigate to the other pages as if that I need to fill in the necessary data so that it satisfies the validator. How can I fix this?
View 1 RepliesHere is a code for my web form control
<asp:TextBox runat="server" ID="txtUsername"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="txtUsername" runat="server" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
<asp:CustomValidator OnServerValidate="checkUsername" ID="CustomValidator1" runat="server" ControlToValidate="txtUsername" EnableClientScript="true" ClientValidationFunction="checkUsername" ErrorMessage="CustomValidator"></asp:CustomValidator>

I am creating dropdown controls in code behind. in some conditions I need to add validation control to dropdowlist. But Validation not firing when I submit button.
If mQuestion.RequiredToAnswer = True Then
Dim mValidator As New RequiredFieldValidator
mValidator.ControlToValidate = mDDL.ID
mValidator.InitialValue = mDDL.Items(0).Text
mValidator.Display = ValidatorDisplay.Dynamic
mValidator.ErrorMessage = "* Required!"
mTableCell.Controls.Add(mValidator)
End If
I have other dropdown controls on aspx page with validation comtrols. Those are working fine. Only when I ddl and validations from code not working?
I have a text box that is intended for an Email address. I am using a Regular eExppression validation control to validate the email address. When I place the following lines of code in a blank web Form, the validator works properly.
<asp:TextBox ID="Email" runat="server" CssClass="DefaultTextBox TextboxWidth" MaxLength="80"></asp:TextBox>
<asp:RegularExpressionValidator ID="valEmail" runat="server" ControlToValidate="Email" ErrorMessage="Invalid Email address" SetFocusOnError="True" ToolTip="Invalid Email address" ValidationExpression="w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*">*</asp:RegularExpressionValidator`>
However, when I use the validation control within a CreateUserWizard control, it does not seem to fire but other validation controls (Required and Custom validators) do fire, but not the regular expression validator above for validating the address. The following is my complete web page. The two controls above appear unchanged in the code below, they are simply embedded into the wizard control mentioned.

I created some required field validators and a validation summary control. When I get an error it displays next to the control its validating and also inside the validation summary control. I only want the error to display in one place; inside the validation summary control. I tried making the required field validator invisible but then it didn't display anywhere.How can I get the errors to only display in the validation summary control? There is no need to display them twice it just clutters up the page.

View 1 RepliesI have a web app using validation control such requiredvalidator. When I run it from VS 2008 directly, it worked perfectly (validated the missing input). But the moment I published it to IIS, it does not validate it anymore..
View 2 RepliesIn my Website I have header control (header.ascx) and footer control (footer.ascx).In header.ascx one textbox and one button is there. Textbox meant for accepting search string.
In footer.ascx one textbox and one button is there. Textbox meant for accepting Email-Id.
Now in validation of header.ascx I had done blank checking by JavaScript. And in validation of footer.ascx I had done blank-checking and e-mail checking by javascript.
In both the control the textbox and the button both resides under Panel control whose
DefaultButton property set to the respective button ids. So that if User write write something and press ENTER key from keyboard then it should do whatever respective Button_Clicks will do.
Now My problem is suppose I place the mouse cursor in footer.ascx's textbox and press the ENTER key it validates properly but after that if I place the cursor inheader.ascx's textbox and press the ENTER then it is not working. Again If I do the opposite then also first one will fire but in case of second it is not firing .......
I am facing an interesting issue related to user control validation. I have a strongly typed user control with address entity. I have also created the address entity metadata class with validation definitions. This user control is basically to search and get the address based on the pincode user input. Pincode field is part of the user control and I have defined the required field and regexp validator for pincode field in the address metatdata class.
Now the user control is partially rendered in the customer page where I want to validate the pincode field in the customer page when the user clicks the search button in the user control.But the strange thing is the validation is not working as expected when I click the search button but when I bind the form collection to the entity using update module, I am getting an error. Can anyone help me what all I need to consider in the control ascx page and in the customer aspx page and in the controller?
I have applied some asp validation controls on a page ,but on clicking Save button data is getting saved without throwing any validation . But as I am entering data for the next time and then click save button then it's working.

I tried the causesvalidation property, but the validations are still triggered.
How can I do this in c# / asp.net?
jQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.
View 1 RepliesI have a radcombobox in radgrid nested inside FormTemplate:
Code:
<telerik:RadComboBox Skin="WebBlue" Width="250px" Height="150px" runat="server"
ID="TitleCombo" OnDataBound="Title_DataBound"
SelectedValue='<%# Bind("Title") %>' AppendDataBoundItems="true"
OnSelectedIndexChanged="Title_SelectedIndexChanged" AutoPostBack="true" />
then i insert an item to the top of list (at zero index):
Code:
protected void Title_DataBound(object sender, EventArgs e)
{
var item = (RadComboBox)sender;
item.Items.Insert(0, new RadComboBoxItem("Select title...", "0"));
}
It works perfect but, IF the Title field is zero and you Click EDIT LinkButton it throws an exception: Selection out of range Parameter name: value I would say that it's expected as zero index does not exist at the moment when i click edit button. I bind the combo from within RadGrid1_ItemCreated event.
I am using a MultiView inside an UpdatePanel with several views within it and a button on each that is supposed to validate the controls on the current view before moving onto the next view in the sequence (a bit like the Wizard control except I wanted more freedom).
I am using an LinkButton but the problem is that the LinkButton is not causing validation -- I have also tested with an ImageButton which isn't causing validation either. However, when I use a normal Button, the validation does work. I have grouped my validation controls into a ValidationGroup and made sure that CausesValidation is turned on.

I have a gridview control set up like so:
[Code]....
I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:
[Code]....
The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.
I am displaying some data in a table. For each record displayed I want to create a link button which when clicked should open a new page. My link button when clicked comes back to the same page instead of going to redirect page in the button click event.

View 1 RepliesI have a UserControl with a ModalPopupExtender that shows a Panel with a GridView. I use this UserControl inside an UpdatePanel.The issue is that I'm using a LinkButton in a TemplateField of the grid that sends a Command and it is working well. If I replace the LinkButton with an ImageButton, the AJAX call raises an error 500 (and I don't know how to debug it). As I understand, the ImageButton will send the same CommandName to the same OnRowCommand handler as the Linkbutton.
View 2 RepliesI need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?
