I have a grid within a form-tag. Each row in the grid has two buttons, wich of one is of type submit. I thought that only the submit button would fire of the form submission. But all buttons actually post the form.
Why is that? What's the reason to have the type="submit" tag if it's not taken into account?
And how could I solve this? I need multiple buttons in some of my grids.
#using (Html.BeginForm("Action", "Controller"))
{
Html.RenderPartial("_TestGrid");
}
And the buttons in this grid:
grid.Column(format: #<text><button>Do something</button></text>),
grid.Column(format: #<text><button type="submit" value="1">Do something else</button></text>
Use <input/> insted of <button>
grid.Column(format: #<text><input type="button" value="Somthing"/></text>),
grid.Column(format: #<text><<input type="submit" value="Save"/></text>)

I want to build a form using react-final-form that has multiple submit buttons, where each submit button sets a different value in the form. Essentially, I want to create a form that looks something like this in rendered HTML:
<form>
Are you over 18 years old?
<button type="submit">Yes</button>
<button type="submit">No</button>
</form>
However, I can't figure out how to make react-final-form treat these different submit buttons as setting values in the form. I tried combining component state, <input type="hidden">, and onClick handlers, like this:
class FormWithMultipleSubmits extends React.Component {
state = {
value: undefined
};
setValue = value => this.setState({ value: value });
render() {
return (
<Form>
Are you over 18 years old?
<Field
name="adult"
component="input"
type="hidden"
value={this.state.value}
/>
<button type="submit" onClick={() => this.setValue(true)}>
Yes
</button>
<button type="submit" onClick={() => this.setValue(false)}>
No
</button>
</Form>
);
}
}
However, that doesn't seem to work -- probably because the value property on the <Field> component is only used for checkboxes and radio buttons.
Can someone give me a nudge in the right direction, for how to solve this properly?
Here's a Sandbox that shows how.
I have view with multiple submit button in ASP.NET MVC and I want validate the form using data annotations, but when user clicks on a particular button, not all submit button, validation must be performed with particular button not all button on view.
#using (Html.BeginForm("Index", "Skill", FormMethod.Post))
{
#Html.ValidationSummary(true)
#Html.AntiForgeryToken()
#Html.TextBoxFor(model => model.SkillName)
#Html.HiddenFor(model => model.SkillId)
#Html.ValidataionSummaryFor(model => model.SkillName)
<input type="submit" name="AddAction" value="Add" id="btnAdd"/>
<input type="button" name="btnreset" value="Reset" />
}
I want that validation will apply only on Add button not on Next button or any button
You can you put "NoValidation" Buttons outside form. This will solve the issue.
If you still need form data, you can serialize it via JS, like this:
$("form").serialize()
and send to server.
Let's suppose I have a form with two submit buttons: save and delete.
How can I remove/disable model validations on delete button?
Assuming you're using standard unobtrusive/jQuery validate; Disable client-side validation by putting a class of "cancel" on the button:
<button type="submit" class="cancel">Delete</button>
This will prevent client-side validation from firing at all in the event of this button being clicked.
For server side, just don't check if the model's valid or not.
For example, if you have a property Name on the model and you want NOT to validate it on delete.
You first need to differentiate if the httppost is coming from the save or delete button.
Add to your Model field IsDelete.
I suggest you add in your view something like:
#Html.HiddenFor(x => x.IsDelete)
Add onclick event to your delete button:
<button type="submit" onclick="javacript: $('#IsDelete').val('true');"> Delete </button>
In the controller do something like:
public ActionResult MyAction(MyModel model)
{
if(model.IsDelete)
ModelState.Remove("Name");
var valid = ModelState.IsValid();
}
You can use two separate forms in the view for the edit and delete.
Ex:
#using(Html.BeginForm("Edit", "Employee"))
{
//Edit inputs - ex textboxes for employee details such as name, age...
<input type="submit" value="Edit" />
}
#using(Html.BeginForm("Delete", "Employee"))
{
//Delete inputs - ex: hidden input for employee id
<input type="submit" value="Delete" />
}
I have two submit buttons which call the same action method. How can I tell which of these buttons was clicked in the formcollection of the action method (without setting the value property of the buttons)?
HTML code for buttons:
<input type="submit" name="button" />
<input type="submit" name="button" />
Action method as:
public ActionResult submitted(FormCollection form)
{
}
i know how to do if we have a value property, but I just want to try like this without value property. How can this be done?
thanks,

The best thing to do, is intercept the click action to set a hidden form variable before the form is submitted, e.g.:
<script language="text/javascript">
$("form input[submit]").click(function() {
$("#buttonSelected").val("some unique value here");
});
</script>
Where you might have a hidden input:
<input type="hidden" id="buttonSelected" name="buttonSelected" />
That way, you can then check the specific "buttonSelected" form value to figure out which button was pressed.
I have two submit buttons in one form. I want to call different actions in both buttons. Is there any way to accomplish this without using JavaScript.
Calling different actions is not possible without javascript. You could call the same controller action and inside this action determine which button was pressed using the name property:
<% using (Html.BeginForm()) { %>
<input type="submit" name="save" value="Save" />
<input type="submit" name="update" value="Update" />
<% } %>
and in your controller action:
[HttpPost]
public ActionResult Index(string save)
{
if (!string.IsNullOrEmpty(save))
{
// the save button was pressed
}
else
{
// the update button was pressed
}
return View();
}
Give the buttons different name attributes. Then in your view handler (or equivalent - sorry, not an ASP.NET MVC person), you can check if that button's name is in the HTTP response and act accordingly.
Only one of the submit button names should exist in the response.
Of course there is!
for example, we have following form:
<form>
<input name='customer_name' type='text'/>
<input name='update_user' type='submit' value='Update user info'/>
<input name='delete_user' type='submit' value='Delete user'/>
</form>
when server gets form request there exists only one parameter in the collection: either update_user or delete_user. depends on what user has pressed.
