i am working on web-form for which I have set the validation summary showmessagebox = "true". I have two required field validators, which trigger on a checkbox's OnCheckedChanged event....now my problem is, when I hit submit, the page does not submit if I do not enter any values in the text boxes..which is correct behavior but it does not point out to the error or does not display the message box...i have to scroll up to see what is wrong with he page and then try to enter the values...I do not understand why my message box does not show up or at least why my setfocusonerror which is set to true does not show me the text boxes. find my code below.....

Given the above scenario, I would have thought that submitting the form with a blank ProductId would have been fine because I didn't decorate the ProductId property with [Required]. However I get the error message "The ProductId field is required".
Is there any way to make an Integer property on the model not required?
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 -".
If I have a search object with a list of fields, can I, using the System.ComponentModel.DataAnnotations namespace, set it up to validate that at least one of the fields in the search is not null or empty? i.e All the fields are optional but at least one should always be entered.
I'm trying to use a field validator to make sure one of my list boxes has a selection before the user is able to proceed to the next page. i'm having is that if the validation message is triggered, all of the buttons on my page loose functionality.Meaning, if I purposely trigger the validation control, I can't get rid of the error message and none of my buttons do anything when clicke after this.
The majority of the HTML:
Is there something that I need to add to the code behind of the page or the Java Script that I'm using?
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 the required field validation and Reqularexpressioncontrol in gridview. Fields are in the gridview are in template, but only the edit button it is not templeted, this edit buton is of type Imagebutton and same goes with canel and update.
1_ Do i have to use the Templeted fields for edit/cancel/ and update as well in order to use the validation?
2_Validaiotn should only work when user clicks on the Update button, it should not trigger when cancel button fired.
to explain my problem as simple as i can i have made the following page each textbox is a required field. when i enter valid data in the text box and click the button everything is fine. the problem i am having is that after this button click > i empty out the last 2 textboxes > click the button > the required field validation is not thrown.
the autopostback property being set to true is a must in this case.
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.
I populate two dropdownlist in asp.net. Both are assigned to a required field validator.
The codebehind is as below
the designer code is as below
Now what happens is, when i choose a field from the dropdown and once again when i choose the "-- Select--", the validator appears and then disappears.Where am I going wrong?Why doesnt the validator stay?RegardsHema
I'm a total newbie with MVC -- learning it with MVC3 using Razor.
I just watched the video on PluralSight and was just following along with the example. I created my own Movie and MovieRepository objects. I then created a strongly typed view for adding a new movie. This is what's in the view:
My Movie object looks like this:
If I click submit without entering anything in the input field, I get validation messages i.e. The Rating field is required or if I enter non-numeric data, I get The field Rating must be a number.
I didn't wire this and wanted to understand where this is coming from.
I have a required field validator to validate a dropdownlist. this dropdownlist is an autopostback one, and it's causevalidation property is set to be false.the issue is, when I select the default item, the validation message shows, but the still do the postback. And after the postback, the message disappers.here is the snippet of codes:
