This is the basic question , but I am not sure how the HTML data is handled when submitted through any registration form.
Consider I am having a Registration form where I am entering new customer. And while entring the details of customer I have put some HTML data into the textboxes(simple textboxes ) provided for. Show should I handle this.
Do webstandards allows that?
How can I properly receive these Array of Inputs on asp.net?
[code]....
In php you can access field by $field = $_POST["field"]
$field["name"] and $field["age"] are simply arrays containing names and ages.
I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();
And conversely when it's time to submit.
formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.
I wanted to gather some methods on how to add a variable number of fields to my form (with Add New and Remove buttons). I know that ASP.NET MVC has easy methods, but I'm unable to find any easy methods for WebForms.
Here's what I've used so far:
Adding a new UserControl to a PlaceHolder on PostBack (I've had to fiddle with ViewState to make this work correctly, huge pain) Adding a new row to a grid and having a template field in a grid (works decently but kind of awkward) Actually having several fields on the form by default and hiding/showing them dynamically (fairly easy but you have a set number of fields.)
In my ASP.NET MVC 2 web application, I allow users to create custom input fields of different data types to extend our basic input form. While tricky, building the input form from a collection of custom fields is straight-forward enough.However, I'm now to the point where I want to handle the posting of this form and I'm not certain what the best way to handle this would be. Normally, we'd use strongly-typed input models that get bound from the various statically-typed inputs available on the form. However, I'm at a loss for how to do this with a variable number of input fields that represent different data types.A representative input form might look something like:
My date field: [ date time input
control ]
My text field: [ text input
field ]
My file field: [ file upload
control ]
My number field: [ numerical input control ]
My text field 2: [text input field ]
etc...
Ideas I've thought about are:Sending everything as strings (except for the file inputs, which would need to be handled specially).Using a model with an "object" property and attempting to bind to that (if this is even possible).Sending a json request to my controller with the data encoded properly and attempting to parse that.Manually processing the form collection in my controller post action - certainly an option, but I'd love to avoid this.Has anyone tackled an issue like this before? If so, how did you solve it?Update:My "base" form is handled on another input area all together, so a solution doesn't need to account for any sort of inheritence magic for this. I'm just interested in handling the custom fields on this interface, not my "base" ones.Update 2:Thank you to ARM and smartcaveman; both of you provided good guidance for how this could be done. I will update this question with my final solution once its been implemented.
just starting strongly typed data sets, I have managed to fill my data set and bind the gridview, but now I dont understand where to map the fields ? Inside the business logic layer or presentation layer.
working example to map fields with a select query and with an update .

I have one issue on my localhost running website that is when i submit data from asp.net form . it don't clear the data permanentaly from the page history.like , i submit one record and after this one i double click on the textfields the previous values are shown ?
View 1 RepliesIf a disabled drop-down list is dynamically rendered to the page, it is still possible to use Firebug, or another tool, to tamper with the submitted value, and to remove the "disabled" HTML attribute.
This code:
[code]....
The problem occurs when I use Firebug to remove the "disabled" attribute, and to change the selected option.On submission of the form, and re-creation of the field, the newly generated control has the correct value by the end of OnLoad, but by OnPreRender, it has assumed the identity of the submitted control and has been given the submitted form value.
.NET seems to have no way of detecting the fact that the field was originally created in a disabled state and that the submitted value was faked. This is understandable, as there could be legitimate, client-side functionality that would allow the disabled attribute to be removed.
Is there some way, other than a brute force approach, of detecting that this field's value should not have been changed?
I see the brute force approach as being something crap, like saving the correct value somewhere while still in OnLoad, and restoring the value in the OnPreRender. As some fields have dependencies on others, that would be unacceptable to me.
I dont know whether this simple task or not, but I tried to search in google but couldn't find anything.
I've a asp.net form and user enters some data in the text boxes provided. Whenever user submits the form, browser will save that form data. I don't want this form data to be saved in browser. How can I restrict the browser saving this form data without touching the browser settings?
Application is developed using asp.net and normal text boxes are used here.
I have a gridview that pops up when you click a link. It displays 5 columns.. if you click on the "select" link next to the record, i pass that rows values back to my form and submit the form again.. this works fine if i select a record that has all my form field values..
but if i pick a record that has some values that are empty it doesnt work.. after debugging im finding that for the fields that are blank on the screen, this is the value being passed " " which of course is not empty or null.. so my code doesnt know how to handle that.. i even tried to add .Trim() to the end of the gridview value and still getting that space being passed. How can i pass empty string instead of the for fields that dont have anything to pass?
This is my code i have for the SelectedIndexChanging event of the gridview

I'm new to ASP.NET. I 'm trying to figure out how to make an HTML/ASP page where a user puts in data, either in text fields or selection boxes, and on clicking a submit button all of there selected data gets dropped either into a Access 97 Db or an excel spread sheet. Are there any examples out there of this? Is there a place that has already created this and I can just look and the code and figure it out for myself?
View 1 RepliesCurrently I have a comments section integrated into a blog I am writing. The comments are Ajaxified, when you post a comment the comment list auto updates with the comment you just added. Everything is working great but I would like to do some cleanup after a comment is successfully posted. Specifically I would like to disable the textarea and submit button which I would have no issues doing through javascript by using the AjaxOption OnComplete parameter. To avoid double posts or just plain abuse. I know I will need other safegaurds as well but this is my first step. The thing is Ajax.BeginForm does not give the form an id or name so I can not reference the form in javascript. Is there a workaround here? Can I disable these form controls from the controller?

How am going to use two values in this anchor tag using DataBinder.Eval?
one is anchor tag and other asp linkbutton tag
we want to call user defined function on onclick of anchor tag and as well as linkbutton
is it possible?
I have a form that's used to submit emails for a project. This uses the SMTP Client class and is currently delivering the emails to a local directory , for now.
There is some logic that checks to see if a mailbox is busy or unavailable. A message is displayed for the appropriate situation. There is also some logging and exception handling.
I want to know if there is a way to test this logic, logging and exception handling while this app is local. I don't know if there is a SMTP Status Code that's returned since this is being done locally and not with a real smtp server.
Is there a way to test this locally? Can these values be set manually in the code as a test?

I have a section of a form that I need to handle differently from the rest of form results. In the section that needs special handling I need to iterate over 3 form fields that have the same name. They have to have the same name, I can't change it. The section of the form I am referring to looks something like this:
<td><input name="Color" size="20" value="" type="text"></td>
<td><input name="Color" size="20" value="" type="text"></td>
<td><input name="Color" size="20" value="" type="text"></td>
Using C# I try something like this:
I try to handle it like this:
int i;
for (i = 1; i <= Request.Form["Color"][i]; i++)
{
colorName.Text += Request.Form["Color"];
}
Which leads to the following exception:
System.NullReferenceException: Object reference not set to an instance of an object.
How should I be handling form fields with the same name?

I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?
