I'm using Kendo UI and the time picker is not showing a value also there is a value.
I'm using ASP MVC 4 and loading passing model data to the view. All the data is there in the model.. but for a reason i cannot explain the actual UI is not showing the time.
Code in HTML-View Binding Model to KendoUI:
#Html.LabelFor(model => model.StartTime)
#(Html.Kendo().TimePickerFor(model => model.StartTime)
.Events(e => e.Change("startChange"))
)
#Html.LabelFor(model => model.EndTime)
#Html.Kendo().TimePickerFor(model => model.EndTime)
JS: For startChange
function startChange() {
var startTime = this.value(),
endPicker = $("#EndTime").data("kendoTimePicker");
if (startTime) {
startTime = new Date(startTime);
endPicker.max(startTime);
startTime.setMinutes(startTime.getMinutes() + this.options.interval);
endPicker.min(startTime);
startTime.setMinutes(startTime.getMinutes() + 450);
endPicker.value(startTime);
}
}
First you need to select the time value, then it will bind with your model,
then try for this: use the .text() or .val()
endPicker = $("#EndTime").data("kendoTimePicker").text();

Below is the Kendo grid
#(Html.Kendo().Grid<CS.Web.Models.People.GroupDetailModel>()
.Name("Grid")
.Events(e => e.DataBound("LineItems_Databound"))
.HtmlAttributes(new { style = "overflow:hidden;", #class = "normalgrid" })
.Columns(columns =>
{
columns.Bound(p => p.GroupID).Hidden();
columns.Bound(p => p.GroupName).Title("Group Name").Width(30);
columns.Bound(p => p.Department).Title("Department Name").Width(30);
columns.Bound(p => p.IsBlindSettingsEnable).Title("Blind Group")
.ClientTemplate("<input type=\"checkbox\" #= IsBlindSettingsEnable ? \"checked=checked\": \"\" # enabled=\"enabled\" />")
.Width(30);
columns.Bound("Department").Title("Remove")
.ClientTemplate("<a href='javascript:void(0)' Title='Remove' onclick='return removeUserGroupRelation(+#=GroupID#+);'> <img alt='Remove' src='" + #Url.Content("~/Content/Images/delete_icon.png") + "' /></a>")
.Width(30);
})
.Sortable()
.Scrollable(scrollable => scrollable.Virtual(false))
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("getAssignedGroups", "People")
.Data("setRoutesValues")
)
//new { MerchantId = ViewBag.MerchantId, StartDate = Model.StartDate, EndDate = Model.EndDate }
)
.TableHtmlAttributes(new { #class = "grid_1" })
)
Below is the javascript code
var userID = '#ViewBag.UserID'
$.ajax({
url: '#Url.Action("SaveGroupsUserDetails")',
type: "POST",
dataType: "json",
data: { models: kendo.stringify($("#Grid").data("kendoGrid").dataSource.view()), UserID: userID },
success: function (result) {
}
});
Here in my kendo grid there is checkbox column.When i check or uncheck checkbox at CLIENT sied(in browser).And Do post via give javascript $.ajax post,it will not post the values of checkboxes which I have changed on client browser,it shows the values which it was binded from server side.
so,my question is to I want updated values to post on server which are modified on client browser.
I shall be very thankfull if you provide me answer.
You should just update your datasource on checkbox checked :
...
.ClientTemplate("<input type=\"checkbox\" #= IsBlindSettingsEnable ? \"checked=checked\": \"\" # enabled=\"enabled\" onclick='setChecked(this)' />")
...
function setChecked(cb) {
var row = $(cb).closest("tr");
var item = grid.dataItem(row);
item.IsBlindSettingsEnable = cb.checked;
}
and now your datasource is synced with the view
I believe this is because your looking at the actual value of the dataSource and not the grid itself. Your grid is non-editable. You are manually throwing the inputs into your grid and these will not effect the dataSource.
You can take two approaches do this kind of update.
You can leave the grid the way you have it set up and handle this update solely though Java Script.
To do this you will need to look up all the dataItems you need to update manually with JQuery.
You can lookup all of your check boxes with in that grid that are check, then get the relevant dataItem manually. Here is a short example showing how to get a dataItem from a row in the grid.
//checkbox is a JQuery object referencing one of your checkboxes
var row = $(checkbox).closest("tr");
var grid = $("#grid").data("kendoGrid");
var data = grid.dataItem(row);
Once you have all of your dataItems that are relevant you can then post your update. You would then have to reload your grid to get the updated status of these items.
Overall this is not the preferred way to do this kind of update with a kendo grid.
I suggest this second method.
This is the site where I will be pulling examples from: http://demos.telerik.com/aspnet-mvc/grid/editing
First you will need to make your kendo grid editable .Editable(editable => editable.Mode(GridEditMode.InCell)). You will not need the custom template that adds the checkbox anymore. It will automatically add them when you are editing your grid now.
You will need to then set the datasource to have an update function and have your server expect this update.
Your dataSource binding
.DataSource(dataSource => dataSource
.Ajax()
.Batch(true)
.Read("Editing_Read", "Grid")
.Update("Editing_Update", "Grid")
)
And your server side code
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Editing_Update([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<ProductViewModel> products)
{
if (products != null && ModelState.IsValid)
{
foreach (var product in products)
{
productService.Update(product);
}
}
return Json(products.ToDataSourceResult(request, ModelState));
}
By returning this Json object your grid will auto update to the new values. This is the preferred way to edit a grid.
I am want to have a text area with multiple lines and a value in MVC3. I can't seem to define a textareafor or an editorfor that has a #Value attribute which I can set. I want to have something like
#Html.TextAreaFor(x => x.model, 10, 15, new{#Value="try"})
Also, I want to be able to do this in the view because the default value will depend on an attribute of another model used within the same view.
Any thoughts please.
The textarea html element does not support the value attribute. So you can't set its value using #Html.TextAreaFor.
So what you have to do is this:
#model MvcApplication.Models.Model
#{
if (1 > 2) // your logic here
{
Model.Description = "value1";
}
else
{
Model.Description = "value2";
}
}
#Html.TextAreaFor(model => model.Description, new { #rows = "10", #cols = "15" })
Let the html helper handle the rendering.
Use Telerik control
Html.Telerik().EditorFor(model => model.Description)
.Name("Editor")
.HtmlAttributes(new { style = "height:400px" })
.Encode(false)
.Value((String)ViewBag.Contents)
.Render();
I have a grid that I want to show depending on the result of the drop down list. I can't seem to be able to send the values to the select("controller", "action", data) method. How can I do that? I can't get my javascript to handle it.
This is the drop down list
<select id="workoutType" onchange="changed(value)">
#{ foreach (var type in Model.WorkoutTypes)
{
<option value="#type"> #type </option>
}
}
</select>
and here is the grid
#(Html.Telerik().Grid(Model.Approvers)
.Name("Orders")
.DataBinding(dataBinding => dataBinding
//Ajax binding
.Ajax()
//The action method which will return JSON
.Select("__AjaxBinding", "AssetResearch", new { workoutType = ViewData["dropDownValue"] })
)
.Columns(columns =>
{
columns.Bound(o => o.InvestorName).Width(125);
columns.Bound(o => o.ApproverType).Title("Type").Width(100);
columns.Bound(o => o.Email).Title("E-mail Address");
})
.ClientEvents(events => events
.OnDataBinding("onDataBinding")
)
.Pageable()
.Sortable()
)
I tried using Viewbag and sadly I can't seem to pull it off.
$(document).ready(function() {
$('#workoutType').change(function(){
//bind your data here
var data = $(this).value;
// pass into your C# stuff here
});
});
Would something like this work?
this is not the right way to achieve it because the RouteValue cannot be set on the server (when you are rendering the Grid)
One way to achieve it is to use the change event of the DropDOwnList which Phonixblade9 mentioned to make the Grid perform request and fetch its data from the server. This could be achieved through the ajaxRequest method of the Grid.
Here is what I mean:
$(document).ready(function() {
$('#workoutType').change(function(){
var data = $(this).value;
var gridClientObject = $('#Orders').data().tGrid;
gridClientObject.ajaxRequest({workoutType :data});// do not forget to name the parameter in the action again method again 'workoutType'
});
});
I'm using Telerik Grid. I need to set background color for the entire row based on some property in view model. I've tried to do it as below by setting a background in IF statement for each column but backgound applies only on element not all cell (td). Also it seems it's a very "dirty" way to accomplish this task.
#(Html.Telerik().Grid(Model.SomeItems).Name("Grid")
.Columns(columns =>
{
columns.Template(
#<text>
#if (Model.IsOfSpecialColor)
{
<div class="gridRowBackground">
#Html.ActionLink(...)
</div>
}
else
{
#Html.ActionLink(...)
}
</text>).Title("Blabla");
});
You can change it using onRowDataBound event
#(Html.Telerik().Grid<Customer>()
.Name("Grid2")
.DataBinding(d => d.Ajax().Select("Select", "Home"))
.ClientEvents(e => e.OnRowDataBound("onRowDataBound"))
)
and the function is
<script>
function onRowDataBound(e) {
if (e.dataItem.ID == 2) {
e.row.style.backgroundColor = "grey";
}
}
</script>
If you are using server data binding, you can use CellAction. However, if you are using ajax data binding, you will need to use a solution like Tassadaque suggests.
#(Html.Telerik().Grid(Model.SomeItems)
.Name("Grid")
.CellAction(cell =>
{
if (cell.DataItem.IsOfSpecialColor.Value)
{
cell.HtmlAttributes["style"] = "background-color: red";
}
})
Sorry if this is a repeat. I did a search and didn't find anything that exactly matched my situation.
I have a grid that requires a ClientRowTemplate. I have the template working very well.
I need a button in that RowTemplate that calls back to a controller method through ajax. The controller method needs to perform some complex logic and then return a new set of data to the grid which the grid will then need to bind to. I thought this should work in the same fashion as an ajax binding. For instance, when you do a save or delete (using the built in buttons) an ajax method that is attributed with [GridAction] is called and then has an IQueryable returned. The grid automatically binds to this IQueryable.
How do I do the same thing with a custom button? Is it even possible to add a custom button when using a ClientRowTemplate?
Put a link in the clienttemplate of your grid row
#(Html.Telerik().Grid<myModel>()
.Name("myGrid")
.Columns(columns =>
{
#* You can put a link in your client template to trigger a refresh function *#
columns.Bound(o => o.Id).ClientTemplate("<a href='javascript:refreshGrid(<#= Id #>);'>Refresh</a>");
columns.Bound(e => e.col1);
columns.Bound(e => e.col2);
columns.Bound(e => e.col3);
})
.ClientEvents(events => events.OnDataBinding("myGrid_onRowDataBinding"))
.DataBinding(dataBinding => dataBinding.Ajax().Select("Action", "Controller", new { param1 = ..., param2 = ... } )))
Write your code to refresh grid
<script type="text/javascript">
//parameters needed for grid
var x = ...;
var y = ...;
//grid refresh function
function refreshGrid(id) {
//make a call to server
$.post("/controller/action/" + id, function() {
//after making a successfull call to server
//you may update parameters
x = ...;
y = ...;
//and rebind your grid
$('#myGrid').data('tGrid').rebind();
})
}
//grid on row data binding event
function myGrid_onRowDataBinding(e) {
e.data = $.extend(e.data, { param1: x, param2: y });
}
</script>
That's it
EDIT:
ClientRowTemplate example
You need to change only the grid code. The rest is same.
#(Html.Telerik().Grid<myModel>()
.Name("myGrid")
.ClientRowTemplate(grid => "<div class='firstcolumn'><a href='javascript:refreshGrid(<#= Id #>);'>Refresh</a></div><div class='secondcolumn'>Content....</div>")
.ClientEvents(events => events.OnDataBinding("myGrid_onRowDataBinding"))
.DataBinding(dataBinding => dataBinding.Ajax().Select("Action", "Controller", new { param1 = ..., param2 = ... } )))
