Web Forms :: Highlight Textfields That Return Validation Errors?
Mar 19, 2010
I have a bunch of textfields on my aspx page, many of them have a few validators on them, such as required field, and 2 compare values (for a min and max). All is well with those, all the errors I have posting to a validation summary control that gets fired on a button press. I have it put the "*" in red next to the field with the issue as well, however I'm wondering if there is a way I can change the css class of the textfield through code behind when there happens to be an error present on that control.I know how to change the css class of an element through codebehind(c#) but my question is how do I get it to fire only if an error is thrown for it.
I have a question. I have a Parent page (parent.aspx) In Parent page it will call a Pop Up page(pop.aspx) then choose the data from Popup's gridview pass back the data to parent page gridview.
I need an idea how to check/highlight the data which is already selected when user open the Popup again.
We have option in validation summary to show errors in messagebox. But at the same time errors also showed in the page. Any way to hide this. Because of page space i think to use popup but i dont want to siplay in the summary also.
I have serveral long ASP.Net pages, I use RequiredFieldValidator, RegularExpressionValidator and ValidatorCalloutExtender for validations, Submit buttons are typically at the bottom of the pages. The problem I have: if the errors happen at the top portion of the page when Submit buttons are clicked, the forms do not scroll to the top automatically, the users have to scroll up to see the ValidatorCalloutExtender.
I am using a MultiView control inside a FormView to break my form into more manageable sections for the end-user. I am trying to make it so that each time the Next button is clicked, the entire form is validated and a list of the fields that have not yet been completed show up in the Validation Summary.
I would like my users to be able to continue through the MultiView 'wizard' even if they haven't completed all the fields -- they should be able to come back to them later. But I would like the ValidationSummary to display the fields they've not completed that are required as a reminder of what to come back to if possible.
I've tried playing around with Page.IsValid with no success.
[Code]....
The code-behind for the Next button is as follows:
Curious what the best practice is for returning errors to a view from a controller where the error isn't really a validation error, but more like "user not found" or "service timeout" type of errors. (in ASP.NET MVC2 framework)
I've been adding them to the ModelState's model errors, but that doesn't seem appropriate. (although easy to implement and maintain)
Example - A user tries to log in, and their credentials do not match a known user.
I've searched around a lot, and honed this problem down to this case: I'm using the PRG pattern, pragmatically I'm using the same DTO for my post/get actions. It looks like when I have the dto with the data annotation attributes in the get action parameter list, the validation is always displaying errors, every time on initial page load. In some cases this could be desired behavior if you put asterisks in the error message, but how do I get rid of it?
I have some text fields fields of my page say P1, say T1, T2, T3. I also have a link button in my page which links it to another page P2, which also has some textfields. I also have a link button which links it back to page P1.
When i fill in the text fields in my page P1 go to the next page P2 and try to return to P1. I loose the values in t1, t2, t3.
How to retain those values even if i am moving back and forth between these pages
A typical CSS property that I use often is overflow-x and overflow-y. Sometimes I use CSS 2.1 or later properties or selectors. These (correctly) raise a validation error: Validation (CSS 2.0): 'overflow-y' is not a known CSS property name.For years I ignored this, but it kinda feels wrong. It's possible to switch off warning in C# and other languages for a particular line, block, file or project. Is something similar possible for CSS (or HTML) errors or warnings? Instead of switching it all off, I prefer a more granular solution.
We have a number of multi-line text fields on our pages for form submissions. On the backend of things, we have our stored procedures checking for html coding in those fields to help prevent sql injection. In some cases, someone that is completing the form without any malicious intent is copying and pasting from their word resume into our text fields and once they submit the page it fails because word uses html encoding for formatting and such. So is there a way to either prevent pasting in that way or maybe a way to submit the data to sql in plain text?
Just looking for the easiest solution so that the user doesnt have to do multiple things to submit their application. In order to get it to work for anyone having issues, is to have them copy and paste into "notepad" and then copy and paste from there to our form, which strips the html coding.
I have a web form for handling invoices which has a form view. When I'm in insert item template, I need to have various fields. Some of them are contract number, invoice number, register date and other that are easy to handle. But there is a dropdown list related with a table of prices (the table has price name, price initial payment, number of payments, amount of month fee and so on). So, when the dropdown is selected, fields related with price should get their values from price table, and then the user decides to keep them or type in new values. How can I get it done? Should I use a Dynamic populate extender or type all the code behind using SelectedIndexChanged method to populate price related controls?
I have an ASP.net gridview on a webform where user's can select a row. When they select it, the row is highlighted yellow. The problem is that when I sort the table, it sorts properly but the highlight stays on the same line. The data all moves, but the highlight stays put.
What is the purpose and proper use of the max-length property on text fields?
The application I'm working on limits numeric fields to 6 characters... which doesn't work very well for entering millions of dollars... which is why I'm "fixing" it.
I got a view that uses the ajax.beginform tag.This works great but if I want to do some validation to the data and then return a error message to the page it doesnt work for me.Here my code :
I have a C# web forms ASP.NET 4.0 web application that uses Routing for URLs for some reason custom errors defined in the system.web section of my web.config is entirely ignored and it will fall back the IIS errors.
This gets entirely ignored
[code]....
This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.
I have a couple of pages with standard asp.net validation controls such as RequiredFieldValidator etc inside my RadAjaxPanel.As soon as I navigate to another tab in my RadTabStrip the page seems to force validation errors and pretty much "locks" the page even though non of the fields was selected to enter data.Only once all the required fields was entered the page seems to release the "lock" and only then am I able to navigate to another tab / page without even submitting the page.
what might be causing the "lock" and forced validation errors on the page?
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 ?
I just want to add some client side (JQuery Javascript) validation in a web user control. I put an OnClientClick handler and the function gets called. BUT, even if I return "false", the OnClick method always get fired. What am I doing wrong ?
I'm with VS 2010, targeting the 4.0 framework with JQuery 1.4.2. and JQuery UI 1.8.4.
When I build my program, if there's one error that prevents it from running, instead of just getting the one error I'll get around 50 additional errors in addition to the real one such as:
Error 27 Validation (XHTML 1.0 Transitional): This name contains uppercase characters, which is not allowed.
I have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
I am moving an app from Silverlight back to ASP.NET. (Don't ask!) I really liked the ability to highlight ListBox items as the user moved the mouse over the items. I have been Bing'ing all morning and cannot seem to find any way to do this in ASP.NET with an ASP:ListBox. I tried setting the onmouseover event for the list items themselves. But that did nothing.
[Code]....
I then tried setting onmouseover event for the list itself. I can get the event, but I don't know how to determine which item I am over. I only seem to have the selectedIndex. If I am just moving the mouse, I have no selectedIndex.
I'm trying to highlight the content of a textbox when it gets focus. I make a selection from a dropdown and the focus is moved to the texbox, I would like the current content of the texbox to be highlighted. How is this done?
I have a gridview that has a checkbox control for each items. Underneath the gridview, there is a Delete button and the users can delete item(s) by checking the checkbox control and the foreach loop is used to delete item(s). I need to do one check on this delete function - where if an item of the gridview has a filter set to true, then highlight that row and display a message - like the highlighted row cannot be deleted.
how to set a back color of that row using a foreach loop.
