We are using ASP.NET MVC and have a grid with a date column which as a filter. The date filter has datepickers. In the filter datepickers, is there a way to prevent the user from selecting some minimum date (like two years ago).

Getting DropDown to select item by Model value inside Kendo Template

I am trying to get a Kendo DropDownList—declared inside of a Kendo Template script block—to automatically select an item from its list when a data value is provided to the template. I’m not having any luck doing this because I don’t understand how to plumb this particular case. My project has many other Kendo DropDownList controls, and they work just fine, but they are not declared inside of any Kendo Templates.

Basically, I have a parent Kendo Grid with the following declaration (irrelevant Razor omitted for clarity):

@(Html.Kendo().Grid<DocumentUploadViewModel>()

.ClientDetailTemplateId("documentUploadTemplate")

My intention is to provide an editor template for the grid consisting of a Kendo Template script block. At the moment, that template looks like this:

<script id="documentUploadTemplate" type="text/kendo-tmpl">

<div>

<p>ID: ${Id}</p>

<p>Document Type ID: ${DocumentTypeId}</p>

<p>Document Type Name: ${DocumentTypeName}</p>

<p>Path: ${Path}</p>

<p>FileName: ${FileName}</p>

<p>MIME Type: ${MimeType}</p>

</div>

<div>

@(Html.Kendo().DropDownList()

.Name("uxDocumentTypeName#=Id#")

.OptionLabel("Please Select...")

.DataValueField("DocumentTypeId")

.DataTextField("DocumentTypeName")

.DataSource(s =>

{

s.Read(r =>

{

r.Action("GetDocumentTypes", "MyController");

})

.ServerFiltering(true);

})

.ToClientTemplate()

)

</div>

</script>

My parent grid, which is working fine, is bound to a populated DocumentUploadViewModel, and its field values are surfaced in the Kendo Template for debugging purposes. When I invoke my grid’s “edit” button, I see the selected grid item’s bound data appear correctly inside the DIV at the top of the presented template.

The drop-down itself is full of data from the DataSource.Read.Action call, and I can manually make selections. However, I am unsure how to wire the control so that it automatically selects the item specified by the passed-in “DocumentTypeId” field. I do see this field value rendering correctly in the DIV, and the visible ID matches one of the items found in the drop-down’s data.

Normally, I would write @Html.Kendo.DropDownListFor(m => m.DocumentTypeId) but I can’t get at the “model” passed into the Kendo template. I have tried .BindTo("#=DocumentUploadViewModel.DocumentTypeId") as well as other variations, to no avail.

Telerik Grid UI MVC - data disappears after load

Hello, I am using Kendo Grid on my MVC site. Loading data using AJAX call. But, the data disappears right after loading. Below is a code for Grid control in the view.

@(Html.Kendo().Grid<SomeViewModelClass>()
.Name("criteriaGridDiv")
.AutoBind(false)
.DataSource(datasource => datasource
.Ajax()
.Model(module =>
{
module.Id("ID");
module.Field("ScoreValue", typeof(int));
module.Field("ProjectID", typeof(string));
module.Field("CallMonitoringFormTypeID", typeof(int));
module.Field("FailureOnNotMet", typeof(bool));
})
.Create(create => create.Action("Create_Criteria", "Permission", new { ModuleId = ViewBag.ModuleId }))
.Update(update => update.Action("Edit_Criteria", "Permission", new { ModuleId = ViewBag.ModuleId }))
)
.Columns(columns =>
{
columns.Bound("ID").Visible(false);
columns.Bound("ProjectID").Visible(false);
columns.Bound("CallMonitoringFormTypeID").Visible(false);
columns.Bound("CriteriaStatement").Title("Criteria");
columns.Bound("ScoreValue").Title("Score Value").HtmlAttributes(new { style = "max-width:100px;" });
columns.Bound("FailureOnNotMet").Title("Fail call if Not Met?").ClientTemplate("<input type='checkbox' #= FailureOnNotMet ? checked='checked':'' # class='failureOnNotMetCheck' />");
columns.Command(command => command.Edit()).HtmlAttributes(new { style = "max-width:200px;" });
})
.ToolBar(toolbar => toolbar.Create().Text("Add New Criteria").HtmlAttributes(new { id = "radGridButton" }))
.Editable(editable => { editable.Mode(GridEditMode.InLine); })
.HtmlAttributes(new { style = "max-width:90%;height:500px;" }))

Any thought on what I am missing here?

Thanks in advance.

Display/Modify pre uploaded files in Kendo Grid in ASP MVC

Hi,

I need to display data in grid where it needs to display pre uploaded files in one of the column. User will also be able to edit the column and be able to delete or upload new attachment in the column. The user should be able to upload multiple files and the grid should display multiple files if the user has already uploaded previously.

I have been able to display data in grid with one attachment but having hard time to figure out how to display multiple files and enable uploading multiple files in the grid.

Here is my code:

Razor View:
Test.cshtml

@using Kendo.Mvc.UI

@{

ViewBag.Title = "Test";

}

<h2>Test</h2>

<input id="btnSearch" type="button" value="Search" class="btn btn-default icon-btn-input" />

Web Grid UI MVC In-cell/batch edit with a bool? column I still get drop list when clicking next to checkbox.

So I'm using 2016.1.412 Telerik controls. MVC Grid UI.

I've followed this (http://www.telerik.com/support/code-library/checkbox-column-and-incell-editing) in order to get one of my boolean? columns to only show a checkbox and allow single click changes. It works if I very carefully click on the check box. If I click (within the cell) but next to the check box I get the drop list with the values "true, false, not set". How do I get rid of the drop list?

1.columns.Bound(p => p.SendTo).Template(@<text></text>).ClientTemplate("<input type='checkbox' #= SendTo ? checked='checked':'' # class='sendtochkbx'/>")

2. .Title(GridColumns.SendToPorzio)

3. .Filterable(true)

4. .HtmlAttributes(new { style = "text-align: center;" })

5. .Sortable(false)

6. .Width(150)

7. .Locked(true)

8. .HeaderTemplate("Send To Porzio <input type='checkbox' id='masterCheckBox' onclick='checkAll(this)'/> ");

1.$("#SpendGrid").on('click',

2. '.sendtochkbx',

3. function () {

4. var checked = $(this).is(':checked');

5. var dataItem = grid.dataItem($(this).closest('tr')); //grid is defined earlier in code block

6. dataItem.set('SendTo', checked);

7. });

Most places I used the kendo controls (Kendo helpers) however there are some places in my application where I've had to use the standard html helpers or just the regular markup.

In those cases I would the appearance of the Kendo style. (Checkboxes, textboxes, etc).

How can I accomplish this?

grid.saveRow(); does not call the controller to update

Hi,

I have a where i need to display data and have a button in each row, on click of the button need to toggle the record with selected property as 0 or 1.

I have used a custom command as i do not need to edit the records. and have used a click on the command, below is the code in the javascript method called in the click. But this makes the row editable and then updates the record but there is no post done to the controller, i have set the Update and Create event both. Please can you help and let me know if this is the current way of doing it.

columns.Command(command =>

{

command.Custom("Set").Click("onSetActive").HtmlAttributes(new { @className = "k-icon k-update", @title = "Set" });

command.Custom("Unset").Click("onUnsetActive").HtmlAttributes(new { @className = "k-icon k-cancel", @title = "Unset" });

}).Width(145);

......

.Create(update => update.Action("Update", "My"))
.Read(read => read.Action("Read", "My"))
.Update(update => update.Action("Update", "My"))

function onSetActive(e)

{

e.preventDefault();

var dataItem = this.dataItem($(e.currentTarget).closest("tr"));

var row = $(e.currentTarget).closest("tr");

var grid = $("#Grid").data("kendoGrid");

grid.editRow(row);

dataItem.Selected = 1;

kendo ui grid batch edit - auto select cell on click

I am using the latest kendo Grid script client with batch edit. Here is my code:
$("#Contract").kendoGrid({
columns: [
{
field: "SomeField",
}],
editable: true,
scrollable: true,
navigatable: true,
selectable: "cell"

How do I make the cell selected when users click on a cell?
I saw a demo at http://demos.telerik.com/aspnet-mvc/razor/grid/editingbatch and wanted to do the same but I could not figure which setting is needed. For editable setting, I tried 0,1,and 2 but it does not seem to work like telerik grid.
