Web Forms :: Change Validation Group For Server Controls In Code Behind
Aug 6, 2010
I have individual controls with different groups in two separate divs in an aspx page. I am passing a querystring value to this page and on page load depending on the querystring value want to show the divs n change the validation group.
I am using one datalist control for uploading multiple images.I hv used one Asp:FileUplaod Control and one button in one itemtemplate.I am using reqired field validator and regular expression validator for file upload cntrl I am assigning validation group for both of them on ItemDataBound event of my datalist so that each upload cntrl hv same validaton group as required field and regular expression validator.Now what i want to do is - i want to show my error message in validation summary which is right at the top of the page.I want one know how to write javascript that will assign validation group of my control in datalist on which i click ?
On one page, I have 2 buttons. One that says Clock-in and the other says Clock-out. As of this moment, the application will allow you to click on the clock-in button without having clocked out the previous day and will allow you to click the clock-out without being clocked in. If a user is clocked in and they click the clock-in button again, I would like an alert to pop-up that would say "you must clock out before you can clock in". And if the user clicks clock-out without being clocked in, it should say "you must clock in before you can clock out". I am using VB in the code behind and SQL Server 2005. My current button click events are below:
I have a web forms where i have 10 required field validators for 10 textboxes. Validation group for these required field validator needs to be determined when the page loads. I tried to change the validator in the .cs file but failed.
I am using tabstrip control. each tab page have set of controls and each have different validation group. I have a common button to insert / update the tab datas. Now when a user entered the information in the first tab and press insert button, i need to validate second page also.
So i explicitely called Page.validate() metyhod in the insert button to ensure all the validation passed or not. All working fine. But i need to focus the second tab when user finished first page and not finished ssecond page. How can i focus the tab. I mean any way to check which validation group fails?
I have a table that contains image data type and has more than 20,000 records.I want to change its file group to the new file group. I tried to change it using table designer, but everytime I wanted to save it, it occured an error with this message:
[Code]....
Does anyone know how to change file group using Alter Table query? I'm using SQL Server 2005.
I am a bit baffled... I had my validation working fine till I added a validation group to it. Can someone tell me what i might be missing ? I'm at a loss... As I have another page doing the same thing and it works fine. Page.isValid always comes back as true.( I am just clicking on the button to make all the validation fire off.... )
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?
How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.
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 have one small issue with my page, i have two CollapsiblePanelExtender in my page and some required field validators are used for the textbox controls that are there within the CollapsiblePanelExtender.And i have also assigned two different validationgroups for all the validators.
Say if first validation group fails to validate then i want to expand the first CollapsiblePanelExtender1, similarly if second validation group fails then i want to expand second CollapsiblePanelExtender2.
Surname is always required NI Number OR Reference Number is required Is this beyond the scope of the ASP.NET Validation Controls? The only solution I can think of is writing some bespoke javascript (for client side) and backing that up with some server side code.
I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?
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
