I am working on a UI where I am editing grid in an Ajax Popup Edit. The following data annotations do not work as expected in the popup edit:

 [DataType(DataType.Password)]
        [Display(Name = "Confirm password")]
        [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
        public string ConfirmPassword { get; set; }

        [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }

        [StringLength(500, ErrorMessage = "Image path cannot be more than 500 characters.")]
        [Display(Name = "Image path")]
        [DataType(DataType.ImageUrl)]
        [RegularExpression(@"^http(s?)\:\/\/[0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*(:(0-9)*)*(\/?)([a-zA-Z0-9\-\.\?\,\'\/\\\+&%\$#_]*)?$", ErrorMessage = "Image path format is incorrect.")]
        public string ImagePath { get; set; }

Currently for Add/Edit both, I am getting a minimum password length should be 6. Also both for Add and Edit I get "Image path format is incorrect" even when there is nothing typed in that field

In addition to the above
On Edit - I do not want the password to be required. On New I want password to be required.

Thanks

i have implemented Custom Binding.I get error like "object reference not set to an instance of an object" when Group a column which is complex Type(Order.Name).

public static IEnumerable<AggregateFunctionsGroup> BuildInnerGroup<T, TObject>(IEnumerable<TObject> group, Func<TObject, T> groupSelector, Func<IEnumerable<TObject>, IEnumerable> innerSelector)
{
return group.GroupBy(groupSelector)
.Select(i => new AggregateFunctionsGroup
{
Key = i.Key,
Items = innerSelector(i)
});
}

public static Func<IEnumerable<TObject>, IEnumerable<AggregateFunctionsGroup>> BuildGroup<T, TObject>(Func<TObject, T> groupSelector, Func<IEnumerable<TObject>, IEnumerable<AggregateFunctionsGroup>> selectorBuilder)
{
var tempSelector = selectorBuilder;
return g => g.GroupBy(groupSelector)
.Select(c => new AggregateFunctionsGroup
{
Key = c.Key,
HasSubgroups = true,
Items = tempSelector.Invoke(c).ToList()
});
}

public static IEnumerable<AggregateFunctionsGroup> ApplyGrouping<T>(this IQueryable<T> data, IList<GroupDescriptor> groupDescriptors)
{
Func<IEnumerable<T>, IEnumerable<AggregateFunctionsGroup>> selector = null;
foreach(var descriptor in groupDescriptors.Reverse())
{
var tempDescriptor = descriptor;
if(selector == null)
selector = g => BuildInnerGroup(g.Select(p => p), p => p.GetType().GetProperty(tempDescriptor.Member).GetValue(p, null), i => i.ToList());
else
selector = BuildGroup(p => p.GetType().GetProperty(tempDescriptor.Member).GetValue(p, null), selector);
}

return selector != null
? selector.Invoke(data).ToList()
: null;
}

For simple field it is working well.When I Group a field with complex type(Order.Name) i get the above error in ApplyGrouping function.In debug mode i see in ApplyGrouping function,the tempDescriptor.Member property value is Order.Name.I need to Split the property on dot(.) and make the grouping(like in the sorting which i already implemented for complex type). Please give a suggestion for grouping.i post the same issue in StackOverflow

Hi guys, I have this grid:


and I noticed that the delete action is called as soon as the user click on remove command, even if the confirmation popup is displayed.
I need to invoke the action only on the confirm from the user. I search a bit online but everyone is doing this with a custom popup.
I remember, however, that in another project I've done that automatically, but I wasn't using MVC back there.

Thanks

See gif,

There are 10 rows, but I can't scroll any further, I believe the JS isn't calculating the multi-line column height correctly.

So I have a kendo Grid and a datasource populated by an ajax call.

the grid has groupable set to true. 
when someone groups by a column I'd like to automatically select the first row in the first group.   I also have a button somewhere outside the group which needs to do the same this.

I am basically trying to make sure the first row in the grid is selected whatever the user is doing, group or not.

grid.table.find('tr:first'); this line correctly identifies the first row BEFORE any group is added but if I try that after the grouping is done it will simply return the first group's header and it's not what I need.

How can I achieve this?

I recently switched my grid from using the .Read() method to binding to local data.  My grid works fine when there are no items in my IEnumerable to start with.  When I have an item in my IEnumerable, I see two grid areas in IE9, and the submit buttons on my form don't work.  I don't see this behavior in Firefox 27.0.1 or in Chrome.  If I switch back to using the .Read() method the grid displays fine, but I would like to use the local option.  Do I have a configuration issue in my grid that only affects IE with local data, or is this an IE bug?  I have attached an image of how the grid is rendered in IE 9.

Here is my grid configuration:

Hi,
We are using a kendo treeview as our main menu in our MVC app.  It's in our default layout.
The question is, how do we keep the currently selected menu item selected and showing as they navigate from controller/view to controller/view? Should we use cookies? Session? Any sample code would be great!
We are trying to get up to speed on Kendo and want to do thing "right" from the get go.
Any help would be great.
Thanks ... Ed

Anyone know if this grid can have custom layouts that allow inline editing, but don't cause a popup?  I would like to just rearrange the rows to be stacked, but still be editable. Here is an simple layout example below:

LastName     Phone
FirstName     Email

I am trying to implement a custom validator to require that a user enter a certain number of rows in my grid.  I am applying the validation attribute to the IEnumerable<T> that provides the rows for my grid.  The validation code gets called on the server side, but on the client side I don't see the data- properties anywhere in the page.  Is it possible to run a client-side validator for the grid as a whole?  If so, what do I need to do so that the client-side code is run?  I'm guessing that because there is no direct reference from the grid to the property, that the client-side validation is not being wired up.  Is there a way to work around this?  Could I bind the grid directly to the property somehow instead of going through the .Read() AJAX method to get the data?   

Here is my validation attribute:


Here is the JavaScript piece:

Here is my grid definition:


Any help would be appreciated.

Thanks,

Hi. New here.

Below is a ListView and a DropDownList, as simple as possible, calling the same Web API for their data. 

The DropDownList works well. The ListView does show anything. What am I doing wrong?

The ListView API call is: http://localhost/api/vehicles?sort=&group=&filter=
The DropDownList API call is : http://localhost/api/vehicles

I would have assumed the .ServerOperation(false) would have removed the sort&group&filter from the Get. In any case, the JSON returned by both Gets is exactly the same. 

Thanks

PS: in case this is relevant, the Web API controller was generated by the Telerik Data Access Wizard and unmodified
