Web Forms :: Highlight Textbox Border When Required Field Is Empty?
Apr 26, 2010
I'm developing an aspx page with vb code.
I am trying to highlight textbox border in red instead on showing an error message in summary. I'm using a required field validator to validate the empty textbox How can i do so?
I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
in my module there are data of students for H.S.C., C.E.T, AND H.S.C+C.E.T. so when i run the gridview page all the data of all streams together is displayed so i sort the data using a dropdownlist...means if 1 select the H.S.C in dropdownlist only the H.S.C students are being displayed.so the problem is when i sort the data by selecting a stream in dropdownlist at that time the error message of required field validator is displayed...
1) I wil select the stream from Dropdownlist and click the "sort button"
2) After the data is been sorted and i will enter the values in the TextBox and if i'll miss any of the textbox blank and i click on the "submit button" after dat the error should be displayed
in my website there is a module in which i m fetching the data of present students in the gridview and i m entering there marks in the gridview textbox column (created by using item template)...I want to add required field validation to the textbox columns so that after clicking the submit button there should be an error message displayed if any of the textbox is empty...
I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".
I have a sql database that on some field will have a empty string/field. I am using a Datalist to display my results. How do I not make the labels that are empty not display? Currently if the field is empty it will leave a space there which my goal is if the field is empty do not leave a white space instead move the other colunms up.
I have a scenario which is there's a gridview with remove button and also a textbox.
Example:
The value of textbox is 2, and rows of gridview is 5 so the rows from 3-5 will be highlighted. And if the user removed the first row, the highlight should be follow. The highlighted row now is 3-4.
i have a gridview that directly bind to a dataset.Hence there is no column in code behind for me to control the boarder color and border style.I try my code in RowDataBound, but it does not take effect.
I want to change the background and border color of textbox when its validated bay validation control. Here ErrorMessage="*" But is want also change the background or border color of textbox.
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?
textbox1 = "Hello bob, How are you" textbox2 = "Hello cad, how are you"
I have looped through each text box and know that the area I want to highlight on textBox 2 is between the charaters 7 and 9. How do I highlight only these characters as Bold and with a yellow background?
I'm trying to write a form for a user to leave a testimonial on the website. I would like a group of inputs related to the users name (title, firstname and surname) or an input for their company name to be required. They can leave both if they like, but they must at least either fill in all the inputs related to their name or the input for their company name.can I do this with the RequiredFieldValidator?
I have a contact page with fields like E-mail Address, Name, Subject, and Message. I use a RequiredFieldValidator on each text box. They work fine when I test it with the Visual Studio built-in development server, but on IIS7, they don't work and they allow the Send button's click event to be fired.
I have 2 date fields - From and To Date.Both are using required field validators, regular expression validtors and compare validators. When the user enters an invalid date range, e.g. 02-29-2010 to 02-29-2010 (non-leap year), the comparevalidator throws an 'from cannot be greater than to date range' error.Why am I seeing this error when From is not > To.Here's the code snippet
I have a form that contains times and dates. Each of these controls has a required field validator so that the user must put in the date and time. This apprears to work fine in testing. The data is stored in sql tables which are then worked with in the office using an Access Database. The webforms are simply used for gathering the data. In analyzing the data, they are finding that there are instances when no time has been stored. I don't know how the insert information could be saved if the control was blank. To make matters worse, the staff swear that they are entering the times.
Sometimes while registering on the website people don't provide correct details like name and e-mailIn order to check correct e-mail it is better to use e-mail activation link send to their e-mail.But how to make sure the user is providing correct name ?I am really impressed by the Facebook name recognition system, it we try to use any word which is not a name, it asks you to enter a valid name.Is there any way we can make use of asp.net requiredfieldvalidator to check if user is providing a correct name or not ?I know we can make use of requiredfieldvalidator to see how many alphabets / special symbols etc butIf we put minimum alphabet requirement - in that case user can enter "....." and can easily bypass the requiredfieldvalidator or a user can easily write "iamfakeuser" instead of name and bypass the requiredfieldvalidator. question is how to check if name is correct or not just like facebook registration form ?
I am working on a web application and I want to incorporate the jQuery Highlight functionality. The way it is set up now is there is a gridview with a link button to add an entry. When you select the link button to add an entry a form appears to fill out all of the information. Once the information is filled out and the user selects "Insert" I would like to have the insert onClick function in the code behind somehow activate the jQuery Highlight command. I can not seem to get this to work.
I've an aspx page with a couple of textboxes, one of which is populated with text from a sqlserver, is it possible to highlight certain words within the text box that match a search critrea? I've opted for textbox to display the text as that seems to be the only control that will format the text correctly. Incidently I'm using vb.net as my code behind
