Forms Data Controls :: Dynamic Error Messages For Validation
Mar 14, 2011I have the this current design. I use a web service/jquery perform client-side validation and to return 1 of 4 integers. At present I store it in a hidden field but it could be passed directly. I then deploy4 validators that when validated, validate the integer and trigger a custom error message. The ideal scenario I would like to be able to do this with one validator and switch the error message accordingly. On the server side the code could look like this:
[Code]....
As you can see my error messages are held as strings elsewhere which I reference for continuity throughout the project. unformtunately I don't know how to achieve this client-side by calling a javascript function. Sure I could hard code the messages in the javascript file as well, but this would mean that they were held in two places and suseptable to error. It may be an option to return an error message in the web service rather than an integer and trigger if it is blank.

Data Controls :: Validation For Dynamic Gridview Cells
Dec 8, 2013In my gridview i have
I have a dropdownlist with tables. if i select the table, based on the columns the gridview displays.
One table contains 9 columns and other contains 40 columns... for example....see the below.
Insert/Edit   RoleUID  RoleID   Role  Desc  ....etc columns
Here RoleId, role are mandatory fields... i am making those two with "*" red color. but if i click on the "INSERT" then i need to get a alert msg that the roleid is mandatory.. you should enter in interger value, and if "role" is null then same like "Role is mandatory... plz enter character value"
I don't have any template fields in the gridview. i make autogeneratecolumns=true in my grid.
I need validation for the dynamic gridview cell... where there is no columns fixed...
I used the below code ... for INSERTÂ
for (int j = 3; j < cellCount; j++)Â Â {

Web Forms :: Dynamic Controls Versus Building Dynamic Page
Jan 28, 2011Lets say I have a Web Application with a menu of products. When a user clicks a menu item, then create and display a dynamic set of controls in an Update Panel. I am currently doing this however the PostBack and recreation of controls is tedious and resource intensive.
Not sure about this but is it possible to build a webpage with controls on it, then display it in update panel or IFrame? Then on post back you wouldn't have to recreate everything all over again?

Forms Data Controls :: Dynamic Gridview Inside A Dynamic Gridview?
Oct 9, 2010If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?

MVC :: Select And Update Dynamic Checkboxlist Values?
Mar 9, 2011I have a page with 5 seperate collections of checkboxes that are created according to entries in a database...i.e. the checkboxes ID values correspond to a selectable list from a database.
I also have a list of records which is a subset of the list of checkboxes and refers to those checkboxes within the list that have been checked (selected).
So...2 tables...one with the complete list of checkboxes, and the other with the list of those that are to be marked as checked
I've built the checkboxes in the view by passing the list via the model and using a for loop as so:

I've also passed the list of checkboxes that should be checked via the model. My problem now is initially how to populate those checkboxes that should be checked.

Web Forms :: Adding Dynamic Fields And Dynamic RequiredFieldValidators?
Jul 28, 2010So am adding fields in the code behind and now want to add required field validators. Kicker, I think comes into play becasue all this is in a master page.

So when I add the required field validator and tell it the control to validate is tb4, I get the yellow screen of death telling me thtat tb4 does not exist... cause it's the long huge master page ID.

MVC :: Dynamic Client-Side Validation?
Jun 10, 2010I have number of fields in the view, which I am dynamically showing/hiding on the client side using jQuery e.g, if user enter 'abc' in first field, I will show three more fields and if he enters 'xyz' then I will show only single field.
I am using data annotations based Asp.Net MVC 2 validation (MVC 2 RTM) and the requirement is that only visible fields should be validated. I have added some code on the server side and the partial validation is working fine there but the issue is on the client side. Actually it works fine first time but fails after wards.
Here is what I am doing:
In $(document).ready event I am popping all the validation stuff in the array as shown below:
for (i = 0; i < numOfFields; i++) {
fValidationArrL[i] = window.mvcClientValidationMetadata[0].Fields.pop();
}
When I show/hide the fields I push only those fields which are visible like this:
window.mvcClientValidationMetadata[0].Fields.push(fValidationArr[i]);
Th I run below two statements to refresh the stuff:
Sys.Application.remove_load(arguments.callee);
Sys.Mvc.FormContext._Application_Load();
It works fine first time but second time when I do show/hide again, it appends the validation list instead of replacing it. So at the end it will validate all the fields that I have shown to the user at some point of time.
Validation - MVC 3 Validate Dynamic Form Fields?
Mar 10, 2011I'm working on a very dynamic site build at the moment. What I'm trying to do is creating something like a survey that can be created dynamically from a control panel. In the control panel you add input fields (these are saved in a database), what the user then see is a form that I generate from the database. So if I add 3 input fields to the database the survey will contain 3 fields. If I add 20 fields the survey will have 20 fields.
Now my problem is that I want to validate these fields, and I would like to be able to hook me in with the standard validation flow. I can't create a Model with validation rules since the number of fields and their names are dynamic the only thing I know is what kind of data that is expected in every field (this rule is found in the database). In an ordinary case I would get the automatic highlighted fields that are not valid and so on thanks to the built in validation flow with ValidationResult and so on.
So the question now is can I somehow simulate parts of the validation and then hook me back in with the validation result, and if not valid, the form prints the error messages and fill the fields with the data that was given?

View 1 RepliesCreate Dynamic Button With Dynamic Text?
Jan 7, 2011I have a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events.
Clarification:
There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items?
