Custom Popup Edit Template troubles

Hi,

I have a template that I want to display certain controls if I am editing and others if I am creating new.

I have the code shown below but it does not work. It seems that the template is initialized at the time the parent is loaded.

How can I display the dropdown list in create mode and the textbox in edit mode?

The code below doesn't work but shows what I am trying to do.

Thanks … Ed

<div class="form-group">

<label class="LabelStyle">Vial</label>

@{

if (Model != null && Model.IsCreatingNew)

{

@(Html.Kendo().DropDownListFor(m => m.VialId)

.AutoBind(true).DataValueField("VialId").DataTextField("VialName")

.DataSource(source =>

{

source.Ajax()

.Read(r => { r.Url("?handler=VialsRead").Data("forgeryToken"); });

}).HtmlAttributes(new { style = "width:150px" }))

<span asp-validation-for="VialId" class="text-danger"></span>

}

else

@(Html.TextBoxFor(m => m.VialName, new { @class = "border-0", @readonly = "true", @style = "width:50px; margin-top:-8px" }))

}

</div>

Update UI grid using response data from Ajax call

Hi,

I'm using the UI grid in ASP.NET Core using local data. The grid is populated using the page model.

If the user wishes to delete a record, after confirmation, I use an Ajax call to the controller action to perform some magical work and delete the selected record. The ajax call returns successfully, with the updated record set...minus the recently deleted record.

For the life of me, I can't get the newly updated json dataset to refresh the grid. Is this even possible?

Page model

public class RoleListViewModel {

public string GridTitle { get; set; }

public IEnumerable<RoleGrid> RoleList { get; set; }

}

Page code with the grid.

@(Html.Kendo().Grid<RoleGrid>(Model.RoleList)

.Name("roleGrid")

.Columns(columns => {

columns.Bound(m => m.RoleId).Hidden();

columns.Bound(m => m.Name)

.Width(100)

.Title("Name");

columns.Bound(m => m.Description)

.Width(212)

.Title("Description");

columns.Command(command => {

command.Custom("EditRole")

.Text("Edit")

.HtmlAttributes(new { @class = "ds-button", @style = "color: #000000; border: 1px solid #000000;" })

.Click("editRole");

command.Custom("CopyRole")

.Text("Copy")

.HtmlAttributes(new { @class = "ds-button", @style = "color: #000000; border: 1px solid #000000;" })

.Click("copyRole");

command.Custom("DeleteRole")

.Text("Delete")

.HtmlAttributes(new { @class = "ds-button", @style = "color: #000000; border: 1px solid #000000;" })

.Click("deleteRole");

})

.Width(100);

})

.HtmlAttributes(new { style = "height: 517px; color: #323232; font-weight: 400; font-size: 14px;" })

.Pageable(pageable => pageable

.Input(true)

.PreviousNext(true)

.Refresh(true)

.PageSizes(true)

)

.Filterable()

.ToolBar(t => t.Search())

.Selectable(select => select

.Mode(GridSelectionMode.Single)

.Type(GridSelectionType.Row)

)

.Sortable(s => s.AllowUnsort(false))

.Search(s => {

s.Field(c => c.Name);

s.Field(c => c.Description);

})

.DataSource(dataSource => dataSource

.Ajax()

.ServerOperation(false)

.Model(model => {

model.Id(m => m.RoleId);

model.Field(m => m.Name);

model.Field(m => m.Description);

})

.PageSize(10)

)

Controller delete method

public async Task<ActionResult> DeleteAjax([DataSourceRequest]DataSourceRequest request, string roleId) {

if (roleId != null) {

//do some magical code here after selected record is deleted.

return Json(GetRoles().ToDataSourceResult(request));

}

else {

return Json(GetRoles().ToDataSourceResult(request));

}

And finally, the jquery code to handle deleting the selected record

function deleteRole(e) {

e.preventDefault();

var grid = this;

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

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

$('#confirmDeleteItem').text('Delete the ' + selectedRole.Name + ' role?');

wnd.center().open();

$("#yes").click(function () {

wnd.close();

$.ajax({

type: "POST",

url: '@Url.Action("DeleteAjax", "Role")',

data: { roleId: selectedRole.RoleId },

dataType: "json",

success: function (response) {

var grid = $('#roleGrid').data('kendoGrid');

//response.data returns an array of object with roleId, name and description

//the following call clears out the grid data but the grid still shows the correct # of records left

grid.dataSource.read(response.data({ RoleID: roleId, Name: name, Description: description }));

}

});

$("#no").click(function () {

wnd.close();

});

}

Any suggestions on how to best load the response array after the ajax call?

I realize this is not ideal as it's not server or client side dedicated.

Thanks.

Jason

Make panelbar fill available space

hello -- I'm using a panel bar in an MVC app and would like for it to fill the available space,whether the user is looking at the app on a big screen or phone. Specifically, I would like for the panelbar's height to be the same as the viewport and then, when the page is loaded, each of the 5 sections in the panel bar should shrink or grow dynamically to fill the entire panelbar control with no white space left underneath.

Is there a way to accomplish this?

thanks

Can autocomplete be used with ajax binding within a razorpage?

I see the example in the docs setting a custom datasource, but I dont see any mention of using Ajax for the datasource binding? It looks like this wont work with razorpages using one of the page handlers for the datasource read methods. So I guess another option is to use a web api handler and use that?

My problem that the client side validaion not working, I can leave the empty cell without any validation error message and I can press the Update button without restriction. I have data annotations in my model, for example:

[Display(Name = "E-mail cím")]
[EmailAddress(ErrorMessage = "Az e-mail cím formátuma nem érvényes!")]
[StringLength(255, ErrorMessage = "A(z) '{0}' mező hossza minimum {2}, maximum {1} karakter lehet!", MinimumLength = 5)]
[GridFastEditEnabled()]
public string Email { get; set; }

Thank you for help!
