Change hover-text of Telerik MVC grid save icon - telerik

I have a Telerik MVC (not Kendo) grid that uses the default Ajax binding for editing. For some unfathomable reason, when editing a row, the Save and Cancel buttons sport a tooltip of "Edit". I have not found where to define the Title text for the Save or Cancel buttons, only for the Edit and Delete buttons:
commands.Edit().ButtonType(GridButtonType.BareImage).HtmlAttributes(new { #class = "grid-edit-button" }).ImageHtmlAttributes(new { #alt = "Edit", #title = "Edit" });
commands.Delete().ButtonType(GridButtonType.BareImage).HtmlAttributes(new { #class = "grid-delete-button" }).ImageHtmlAttributes(new { #alt = "Delete", #title = "Delete" });
This is code that I copied from another section of the project (unfortunately, written by someone who has since left the company) and it works correctly there. I have had no luck asking Telerik for help, as the MVC libraries are not their most current offerings (but I must use them for legacy reasons).
Does anyone know how to force the tool-tip text to the correct value?

There may be better solutions, but I wound up fixing it through some Javascript trickery (this is what is used by the other instances of this grid. I'd missed it because I had custom edit code for handling the dropdown boxes):
In the grid definition:
.ClientEvents(events => events.OnDataBound("defaultGridDataBound").OnEdit("defaultGridEdit"))
And then:
function defaultGridEdit(e) {
var $form = $(e.form);
if (e.mode == "insert") {
$form.find(".t-grid-insert .t-insert").attr("title", "Save");
$form.find(".t-grid-insert .t-insert").attr("alt", "Save");
}
else {
$form.find(".t-grid-update .t-update").attr("title", "Save");
$form.find(".t-grid-update .t-update").attr("alt", "Save");
}
$form.find(".t-grid-cancel .t-cancel").attr("title", "Cancel");
$form.find(".t-grid-cancel .t-cancel").attr("alt", "Cancel");
}

How to mark Kendo Grid's cell as edited?

I'm dynamically editing some fields using JavaScript. But the problem is Kendo's dataSource doesn't recognize them as changed cells.
Grid's edit mode is InCell.
This is my current JavaScript code:
tablesGrid.tbody.find("input[type='checkbox']").each(function () {
$(this).on('change', function () {
var isChecked = $(this).prop('checked');
var dataItem = tablesGrid.dataItem($(this).closest('tr'));
var currentTr = $(this).closest('tr');
var i = $('td:visible', currentTr).index($(this).closest('td'));
var head = tablesGrid.thead.find('th:visible')[i];
var headName = $(head).prop('dataset').field;
tablesGrid.editCell($(this).closest('td'));
dataItem[headName] = isChecked;
tablesGrid.refresh();
});
});
And if you're wondering about this code, I should note that I'm using client template to show checkboxes. But I don't want the user to double click the cell for editing, once to put it in the edit mode, and another one to change the checkbox. I'm not sure if I'm using the right solution, but the JS code works for sure. If I click in the cell and put it in the edit mode, I'll see the change.
#(Html.Kendo().Grid<grid>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(x => x.field)
.ClientTemplate("<input type='checkbox' class='checkbox-inline' #=field? checked='checked':''# />")
.EditorTemplateName("Checkbox");
Well, the best solution I came up with is to put the cell in edit mode when mouse enters that cell! So instead of the entire JS code in the question, I simply use this.
tablesGrid.bind('dataBound', function () {
tablesGrid.tbody.find('td').each(function () {
$(this).mouseenter(function () {
tablesGrid.editCell(this);
});
});
});
Please let me know if you have any better or more efficient way to use editable
checkboxes inside a Grid.

Kendo Grid - PopUp windows not being removed from the DOM

I have a kendo grid with a custom popup:
columns.Command(commands =>
{
commands.Edit();
}
.Editable(editing => editing.Mode(Kendo.Mvc.UI.GridEditMode.PopUp))
Each time I click the edit button the window pops up but when I close it the window is not removed from the DOM.
I saw this post: http://www.telerik.com/forums/popup-windows-do-not-get-removed-from-dom and Telerik says the issue has been fixed.
What are some things that would cause this behavior?
UPDATED
This grid is nested in a Kendo TabStrip if that helps. Other than that I don't see anything out of the ordinary. The popup is entirely managed by the grid.
UPDATED 2
So I got the un-minimized code for the grid (kendo.grid.min.js, version 2013.3.1119, starting at line 1172), slopped it into my project and modified just the following with the two log statements to verify that destroy is being bound and called:
_destroyEditable: function () {
var that = this;
var destroy = function () {
if (that.editable) {
// My edit
console.log("...destroy() called");
that._detachModelChange();
that.editable.destroy();
that.editable = null;
that._editContainer = null;
}
};
if (that.editable) {
if (that._editMode() === "popup") {
// My edit
console.log("Binding destroy() to 'deactivate'...");
that._editContainer.data("kendoWindow").bind("deactivate", destroy).close();
} else {
destroy();
}
}
},
Each time I click edit and then close the window I see the expected two messages yet the window is not removed. Here is a screenshot of the debugger:
The outlined windows are the dom elements generated.
After much trial and error and deep diving it turns out this problem has to do with our scripts in our site's layout. At some point whomever setup the kendo scripts put in not only the 'kendo.all.min.js' but right after it 'kendo.web.min.js', 'kendo.aspnetmvc.min.js' and then about 10 individual kendo.*.js including the grid.
After viewing this link:
http://docs.telerik.com/kendo-ui/getting-started/javascript-dependencies
I realized that the site is creating these objects multiple times. Removing the script references in accordance to the link above resolves the issue.

Is it possible to change labels of Kendo Grid Editor?

I am using kendo grid and its build-in functionality for creating and updating items.
I'm looking for a way to change Editor labels (title and buttons Update/Cancel).
I found an answer here (Change Button text in Kendo Ui Grid Popup Window) where OnaBei explains how to change title.
However, I still cannot figure out the way to change button names based on whether item is being added or being edited. The same with title, is it a way to change it based on "create"/"update" state?
I assume that it can be done with javascript, but it will probably be a hack and dirty solution.
This can be done in the edit event of the grid. The model event argument has a isNew method which will return true in "create" state. Here is some sample code:
edit: function(e) {
var title = "Edit mode";
if (e.model.isNew()) {
title = "Insert mode";
}
var wnd = e.container.data("kendoWindow");
wnd.title(title);
}
And a live demo: http://jsbin.com/USUpAZUT/1/edit

Is it possible (and if so how) to add an item to the column menu of a kendo UI grid?

So I have a grid and the columns have the good ol' column menu on them with the filtering/sorting/excluding of columns and it all works fine.
The fly in the ointment is that I would like to allow the user to rename a column heading and the obvious place in the UI to allow this is in said column menu.
Something like this:
(where the red bit is just another option that I click on and popup a little window to let me type in a new heading)
Is this possible and how would I do it?
I see that menus can be customized and the grid demo shows how to adjust the stuff in the filter popup but I am not sure how I would add this item (I can see how I would programmatically do the rename but just this getting an option onto the menu has me stumped).
You can use the columnMenuInit event. Two possibilities:
$("#grid").kendoGrid({
dataSource: dataSource,
columnMenu: true,
columnMenuInit: function (e) {
var menu = e.container.find(".k-menu").data("kendoMenu");
var field = e.field;
// Option 1: use the kendoMenu API ...
menu.append({
text: "Rename"
});
// Option 2: or create custom html and append manually ..
var itemHtml = '<li id="my-id" class="k-item k-state-default" role="menuitem">' +
'<span class="k-link"><b>Manual entry</b></span></li>';
$(e.container).find("ul").append(itemHtml);
// add an event handler
menu.bind("select", function (e) {
var menuText = $(e.item).text();
if (menuText == "Rename") {
console.log("Rename for", field);
} else if (menuText === "Manual entry") {
console.log("Manual entry for", field);
}
});
}
})
See fiddle with two alternatives:
http://jsfiddle.net/lhoeppner/jJnQF/
I guess that the point of a filter is to filter, not to make changes on the grid.
But anyways i found this Kendo Post that may help you to achieve what you need.
You can also take a look a this one too.

MVC 3 Bind Model property to 2 fields (e.g. Other Title)

I'm trying to achieve a very common scenario whereas given a list of options to choose from, the last one says "Other" and when selected the user is presented with the input field to specify what "other" is.
In my case, it's a list of Person's titles:
public List<string> TitleList
{
get
{
return new List<string> { "Mr", "Mrs", "Miss", "Dr", "Other" };
}
}
and what I'm trying to do is this:
#Html.DropDownListFor(m => m.Title, new SelectList(Model.TitleList), "Please select...") #Html.TextBoxFor(m => m.Title)
I want the model to bind the TextBox value when "Other" is selected in the DropDownLis, and bind to selected item in DropDownList in all other cases.
Is this achievable without adding an extra property on the Model?
a better solution is not to bind to two fields, instead, copy selected item from a drop-down into bound textbox with some clever javascript:
#Html.DropDownList("ddlTitle", new SelectList(Model.TitleList), "Please select")
#Html.TextBoxFor(m => m.Title, new { maxLength = 10 })
Javascript:
ToggleTitleFields = function () {
var title, txtTitle;
title = $('select#ddlTitle').val();
txtTitle = $('input#Title');
if (title === "Other") {
txtTitle.val("");
txtTitle.show();
return txtTitle.focus();
} else {
txtTitle.hide();
txtTitle.val(title);
return $('span[data-valmsg-for="Title"]').empty();
}
};
$(document).on("change", "select#ddlTitle", function(e) {
return ToggleTitleFields();
});
hope this helps somebody
found a client-side solution: add/remove the "name" attribute from DropDownList. Here's my coffee script:
ToggleTitleFields = () ->
if $('select#Title').val() == "Other"
$('select#Title').removeAttr('name')
else
$('select#Title').attr('name','Title')
Tsar,
Being honest, this isn't a scenario that I've had to deal with before, but is nonetheless a good one. If I were faced with this dilemma and was allowed to use a javascript solution, i'd present a previously 'hidden' textbox when other was chosen. The user would then have to enter the new value into this texbox, which on loosing focus would populate the selectlist and be selected. Then when the form was submitted, you'd have this new value still as part of the exisiting model.
Of course, you could also do a similar logic of showing the textbox when selecting other but this time, do a little logic on the httpost controller action to determine if the 'other' item was selected and then populate the model from the 'textbox' value.
Of course, both scenarios would need a heap of validation, but in principle, either approach would 'work'
