I have an MVC4 application with a MVC defined Grid with CRUD operation. I am using inline Create and get a strange phenomena when I enter two entries in a row. The scenario is as follows:

1.  I click 'Add New Item' button and an empty row appears at the top of the grid with the two editable items open for input.
2. I enter the date new entry and click the 'Update' button.
3. I see a single POST go back to the MVC application and the create works correctly.
4. As the next immediate step I then press 'Add New Item' button again and enter  a new entry.
5. On pressing the 'Update' button I see TWO Posts go back to the MVC application.
          - The first is the new entry
          - The second is the data for the entry entered in steps 1 to 3.

That is rather strange, and my database, which does not allow entries with the same name fails the second (duplicate) entry. If I press F5 or next page on the grid after step 3 then I do not have this problem.

My .razor view is:

The MVC actions are pretty standard copies of the format on your examples site, but with ValidateAntiForgeryToken added.

I must be doing wrong but I can't see it. Your help would be appreciated.

Hello,
can i make a custom razor helper that builds a kendo grid?
For example if i have
@(Html.Kendo().Grid<Namespace.ViewModels.TesttViewModel>()
.Name("Grid")

.Columns(columns =>
{
columns.Template(x => { }).ClientTemplate(
@"<a class='k-button' href='javascript: void(0)' onclick='doLoading(this)' style='min-width:32px!important'><span class='k-icon k-edit'></span></a>
<a class='k-button' href='javascript: void(0)' onclick='deleteRow(this);return false;' style='min-width:32px!important'><span class='k-icon k-delete'></span></a>"
).Width(100);

columns.Bound(p => p.Code).Title(Namespace.Resources.Resources.FieldText_TM_Code);
columns.Bound(p => p.Name).Title(UCMSPayroll.Resources.Resources.FieldText_TM_Name);
columns.Bound(p => p.MaxLength).Title(UCMSPayroll.Resources.Resources.FieldText_TM_MaxLength).Width(130);
columns.Bound(p => p.IsActive).ClientTemplate("<input type='checkbox' disabled='true' name='IsActive' #= IsActive ? checked='checked' : '' # />").Title(UCMSPayroll.Resources.Resources.FieldText_TM_IsActive);
columns.Bound(p => p.IsHour).ClientTemplate("<input type='checkbox' disabled='true' name='IsHour' #= IsHour ? checked='checked' : '' # />").Title(UCMSPayroll.Resources.Resources.FieldText_TM_IsHour);
columns.Bound(p => p.Precision).Title(UCMSPayroll.Resources.Resources.FieldText_TM_Precision);
columns.Bound(p => p.Priority).Title(UCMSPayroll.Resources.Resources.FieldText_TM_Priority);
columns.Bound(p => p.Formula).Title(UCMSPayroll.Resources.Resources.FieldText_TM_Formula);


})

.ToolBar(toolBar => toolBar.Template(@"<a id='addSome' class='k-button k-button-icontext k-grid-add' onclick='createRow()' href='javascript: void(0)'><span class='k-icon k-add'></span>add</a>
<span id='spanAdd' style='display:none;font-size:150%;margin-top:25px'><b>Add</b></span>
<span id='spanEdit' style='display:none;font-size:150%'><b>Edit</b></span>
<div style='float:right;color:black;font-size:150%'><b>measure</b></div>
"

))
.Pageable()
.Sortable()
.Scrollable()

.DataSource(dataSource => dataSource
.Ajax()
.Events(events => events.Error("error_handler"))
.Model(model => model.Id(p => p.PkTallyMeasurement))
.Create(update => update.Action("EditingInline_Create", "Home"))
.Read(read => read.Action("EditingInline_Read", "Home"))
.Update(update => update.Action("EditingInline_Update", "Home"))
.Destroy(update => update.Action("EditingInline_Destroy", "Home"))
.PageSize(5)

)
)

so there is a lot of code,and i would like to use something like in the razor view:
@NameSpace.MyGrid(model)
and this should create all the above code that at least the portions that ar not changing such as the templates,the Pageable,Sortable,Datasource and so on.

Regards,
Daniel

Hi,
I have property i my viewmodel: Email with attribute: [Email(ErrorMessage = "not a valid email address")]
The attribute comes from DataAnnotationsExtensions.
The client error message shows up when using Server side binding but not when using Ajax.

How do I enable client side validation when using Ajax?

Hi.

I am using a Grid  with popup editing.

how can I hide the model.ID from the user in the popup?

Hi,

Is there a way of changing the filename of a file (within the Javascript)  that is about to be posted asynchronously? For example I have tried in the select method of the upload tool, the following:

"select": function (e) {
          e.files[0].name = "changed_named.jpg";
}

However, when the file reaches my MVC controller action, the HttpPostedFileBase object has the original filename. I've also tried doing this in the 'upload' event with no luck.

Thanks,

Hi,

Is it possible to prepare a user interface with a few regions that is separeted by splitters that can be replaceable by drag and drop?

Thanks in advance,

Hello!
I have the problem:
If I use 100% scale , then I see first picture
If I use 110% or 125% scale, then  I see second picture
Why display with 125% scale is so incorrect?

Is there any way to use the virtual scrolling with a pager control?  Everything works fine except if you go to a new page and then try to scroll, it resets to the previous page.

Hi,

I am currently making my first
experiences with Kendo UI and a ASP.NET MVC 4 project. At the moment I have a
list stored in a standard .Net System.Collections.Sortedlist object and would
like to fill a Kendo UI combobox with the values from that list. I also tried
to first build a Kendo datasource object, that contains the elements from that
Sortedlist, but I could not get that to work.

How can I:

• fill a Kendo UI combobox with elements from a .Net System.Collections.Sortedlist

object?

or

• fill a Kendo UI datasource (which I will later use to create the combobox)

with elements from a .Net System.Collections.Sortedlist object?

Regards

Sven
