I'm trying to display a pop up window when a user clicks on a button but I cant seem to get this to work. I can fire the event when using a custom command but I need a textbox and button next to each other in the same column.
Any ideas why this isn't working?
#(Html.Kendo().Grid(Model)
.Name("gridPopup")
.Columns(columns =>
{
columns.Bound(p => p.ProductName).Width(120);
columns.Template(#<text></text>).Title("").Width(110).ClientTemplate(
Html.Kendo().TextBox()
.Name("search_textfield")
.Value("").ToClientTemplate().ToString()
+ " " +
Html.Kendo().Button()
.Name("search_button")
.HtmlAttributes(new { type = "button", #class = "k-primary" })
.Events(e =>
e.Click("SearchButton")
)
.Content("...").ToClientTemplate().ToString()
);
})
.Editable(editable => editable.Mode(GridEditMode.InCell))
.Pageable()
.Scrollable()
.HtmlAttributes(new { style = "height:320px;" })
.DataSource(dataSource => dataSource
.Ajax()
.Batch(true)
.PageSize(20)
.ServerOperation(false)
.Events(events => events.Error("errorHandler"))
.Model(model =>
{
model.Id(p => p.ProductID);
model.Field(p => p.ProductID).Editable(true);
model.Field(p => p.CategoryID).DefaultValue(1);
})
.Read(read => read.Action("ForeignKeyColumn_Read", "Home"))
.Update(update => update.Action("ForeignKeyColumn_Update", "Home"))
.Create(create => create.Action("ForeignKeyColumn_Create", "Home"))
.Destroy(destroy => destroy.Action("ForeignKeyColumn_Destroy", "Home"))
)
)
<script type="text/javascript">
function errorHandler(e) {
if (e.errors) {
var message = "Errors:\n";
$.each(e.errors, function (key, value) {
if ('errors' in value) {
$.each(value.errors, function () {
message += this + "\n";
});
}
});
alert(message);
}
}
function SearchButton(e)
{
alert("Search Button Clicked");
}
</script>
Weird! .Events(e => e.Click("SearchButton")) is not generating the onclick attribute if used inside a ClientTemplate()
Try this, it will work for you, but i will wait for someone to explain it :)
.HtmlAttributes(new { type = "button", #class = "k-primary", onclick = "SearchButton()" })
Edit:
The explanation that I found is here: How do I use a Kendo UI widget inside a Grid client column template?. It says script tags are not automatically evaluated inside a Grid client column template, so any included widgets will not be initialized.
Therefore initializing the nested controls in .Events(e => e.DataBound("onDatabound"))
function onDatabound()
{
jQuery("#gridPopup tbody [class='k-primary']").each(function () {
$(this).kendoButton({ "click": SearchButton });
})
}

I have a grid on Kendo UI that has GROUP, however an error occurs when I ask you to clean the grid data via JavaScript, follow the grid code Razor:
#(Html.Kendo().Grid<ItemViewModel>(Model.FormasPagamento)
.Name("grid")
.Columns(clm =>
{
clm.Group(g => g.Title("FormaPagamento")
.Columns(subitem =>
{
subitem.Bound(e => e.Dias)
.Title("Dias").Width(60).ClientTemplate("#=kendo.format('{0:n0}', Dias)#");
subitem.Bound(e => e.Percentual)
.Title("Percentual").Width(100).ClientTemplate("#=kendo.format('{0:p}', Percentual / 100)#");
subitem.Bound(e => e.Valor)
.Title("Valor").Width(100).ClientTemplate("#=kendo.format('{0:n2}', Valor)#");
})
);
clm.Group(g => g.Title("Parcela")
.Columns(subitem =>
{
subitem.Bound(e => e.ParcelaValor)
.Title("Valor").Width(100).ClientTemplate("#=kendo.format('{0:n2}', ParcelaValor)#");
subitem.Bound(e => e.ParcelaTaxa)
.Title("Taxa").Width(100).ClientTemplate("#=kendo.format('{0:n2}', ParcelaTaxa)#");
subitem.Bound(e => e.ParcelaContratoCambio)
.Title("ContratoCambio").Width(200);
subitem.Bound(e => e.ParcelaStatus)
.Title("Status").Width(80);
})
);
})
.ToolBar(t =>
{
t.Template("<span class=\"adicionarItemGridFormaPagamento k-button k-button-icontext\"><span></span>Adicionar</span>");
})
.Navigatable()
.Editable(a =>
{
a.Mode(GridEditMode.InCell);
a.DisplayDeleteConfirmation("Excluir?");
})
.Scrollable(s => s.Height("auto"))
.Selectable(s => s.Mode(GridSelectionMode.Single))
.Filterable()
.ColumnMenu()
.Sortable()
.Pageable()
.DataSource(da => da
.Ajax()
.Batch(true)
.PageSize(1000)
.Events(e => e.Error("onErrorGrid"))
.Destroy("", "", Model)
.Create("", "", Model)
.Update("", "", Model)
.Model(m =>
{
m.Id(p => p.ItemId);
m.Field(p => p.ParcelaValor).Editable(false);
m.Field(p => p.ParcelaStatus).Editable(false);
m.Field(p => p.ParcelaTaxa).Editable(false);
m.Field(p => p.ParcelaContratoCambio).Editable(false);
}))
)
Follows the JavaScript command to clear the grid data, when it reaches this point the browser code enters into an infinite loop and lock the application:
<script>
var grid = $("#grid").data("kendoGrid");
grid.dataSource.data([]); //ERROR
</script>
This problem does not occur with Kendo grid without GROUP, one would have any idea how to use this call without experience this bug?
I am using ASP.NET MVC5 and Kendo 2015.3.1111.545
I'm using a kendo treeview as a drop target for my grid rows.
This code is giving me the following error when the row is dropped in the treeview: Uncaught TypeError: item.level is not a function.
How can I solve this issue?
<%=Html.Kendo().TreeView()

if (dataItem == undefined) {

In a MVC4 project, I've got a kendo grid that fires an event when a row is selected.
<div id="datagrid">
#(Html.Kendo().Grid<SustIMS.Models.StretchModel>()
.Name("datagrid_Stretches")
.Columns(columns =>
{
columns.Bound(s => s.StretchCode).Title(ViewBag.lblCode).Width(80);
columns.Bound(s => s.StretchMediumDescription).Title(ViewBag.lblDescription);
...
})
.Events(e => e.Change("onChange")) <--------- here's the event
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(15)
.Read(read => read.Action("GetStretches", "MasterData"))
)
)
</div>
So, when I select a row, the onChange function is called:
function onChange() {
var code = this.dataItem(this.select()).StretchCode;
$.get('#Url.Content("getStretchCode")',
{ "code": code });
}
In my controller, the code is retrieved and some operations are done with it.
public void getStretchCode(string code)
{
currentStretch.RoadComponentCode = code;
...
}
This works fine. The problem is, the event is fired every time I select a different row but if I select a row that was previously selected, the event isn't fired and I can't get the code of that row.
Any help?
Add .Selectable() in your grid so it allow you select previously row.
#(Html.Kendo().Grid<SustIMS.Models.StretchModel>()
.Name("datagrid_Stretches")
.Columns(columns =>
{
columns.Bound(s => s.StretchCode).Title(ViewBag.lblCode).Width(80);
columns.Bound(s => s.StretchMediumDescription).Title(ViewBag.lblDescription);
...
})
.Selectable(selectable => selectable
.Type(GridSelectionType.Row) <--------- Add This
)
.Events(e => e.Change("onChange"))
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(15)
.Read(read => read.Action("GetStretches", "MasterData"))
)
)
Script
function onChange() {
var code = this.dataItem(this.select()).StretchCode;
$.post('#Url.Content("getStretchCode")',
{ "code": code });
}
you should add Selectable() before add event like this
.Selectable(selectable => selectable
.Mode(GridSelectionMode.Multiple)
.Type(GridSelectionType.Cell))
.Events(e => e.Change("onChange"))
I'm using a Kendo UI Web Grid in an ASP.Net MVC 4 application.
At the bottom of the code below you'll see a JavaScript function called GetEditChildUrl that accepts a parameter called data. Unfortunately, what gets passed in as the data parameter is the parent row data but I was expecting the child row data. This works fine for GetEditParentUrl. So how do I get the child row data?
#(Html.Kendo().Grid<Application.Models.Parent>()
.Name("grid_parent")
.Columns(columns =>
{
columns.Bound(x => x.Name);
columns.Bound(x => x).ClientTemplate(
"<a href='#= GetEditParentUrl(data) #' class='k-button' style='min-width:0px;'><span class='k-icon k-i-pencil'></span></a>"
).Width(90).Filterable(false);
})
.Scrollable(action => action.Virtual(true))
.Filterable()
.Sortable()
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("Parents_Read", "Parent"))
)
.Scrollable(s => s.Height("auto"))
.ClientDetailTemplateId("client-template")
)
#section Scripts {
<script id="client-template" type="text/x-kendo-template">
<h3>Contacts</h3>
#(Html.Kendo().Grid<Application.Models.Child>()
.Name("grid_child_#=Id#") // make sure the Name is unique
.Columns(columns =>
{
columns.Bound(x => x.Name);
columns.Bound(x => x).ClientTemplate(
"<a href='#= GetEditChildUrl(data) #' class='k-button' style='min-width:0px;'><span class='k-icon k-i-pencil'></span></a>"
).Width(90).Filterable(false);
})
.DataSource(dataSource =>
dataSource.Ajax().Read(read => read.Action("Children_Read", "Parent", new { parentId = "#=Id#" }))
)
.Scrollable(s => s.Height("auto"))
.Sortable()
.ToClientTemplate()
)
</script>
<script>
function GetEditParentUrl(data) {
return "#Url.Action("Edit", "Parent")/" + data.Id;
}
function GetEditChildUrl(data) {
return "#Url.Action("Edit", "Child")/" + data.Id;
}
</script>
}
Try escaping the hash (#) symbols in your column client template.
columns.Bound(x => x)
.ClientTemplate("<a href='\\#= GetEditChildUrl(data) \\#' ...>")
From the KendoUI docs:
Important: The "#" characters used for a template expression should be
escaped when using a column ClientTemplate in a detail template so
that the expression is evaluated in the correct context.
I want to use Javascript Function in Kendo Grid Create.
For that I have defined the Javascript Function as,
<script>
function GetCompanyID()
{
return $("#Company").val();
}
</script>
And I want to use it in Create template of Kendo Grid as,
#(Html.Kendo().Grid<Invoice.Models.ViewModels.DossierViewModel>()
.Name("Dossier")
.Columns(columns =>
{
columns.Bound(p => p.CustomerName).Title("Customer").Width(150);
columns.Bound(p => p.InvoiceNumber).Title("INV no.").Width(100);//.Width(20);
columns.Bound(p => p.InvoiceAmountLC).Title("INV Amount LC").Width(150);
})
.ToolBar(toolbar => toolbar.Create().Text("Add New Dossier"))
.Editable(ed => ed.Mode(GridEditMode.PopUp).TemplateName("New_Dossier")) //Having Different Template for New Dossier
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(10)
.Model(model => { model.Id(p => p.DossierID); })
.Read(read => read.Action("Dossier_Read", "Dossier"))
.Create(create => create.Action("Dossier_Create", "Dossier", new { #CompanyID = GetCompanyID }))
.Filter(filters =>
{
// Show products whose ProductName property contains "C"
filters.Add(dossier => dossier.Status).Contains("");
})
)
)
In that I want to use that Javascript functio as I am currently using in Above code as,
.Create(create => create.Action("Dossier_Create", "Dossier", new { #CompanyID = GetCompanyID }))
But this is not the Way it should be used. Please Help me on this. How can I use that Javascript function into this, ASAP.
You need to use the Data() method of the grid data source to send this data. Something like:
.Create(create => create.Action("Dossier_Create", "Dossier").Data("GetCompanyID")
function GetCompanyID()
{
return {
CompanyID: $("#Company").val();
};
}
Check the grid FAQ for more info and an example.
