I turn to you stackoverflow!
I'm using a kendo ui batch grid with InCell editing set and am wanting to know a way to set a particular column into edit mode.
I've tried using editCell, and so far it hasn't caused any of the cells to go into edit mode :(
In this particular case, we have a ClientTemplate column specified which has a button (really its a link...) in it. When the user clicks the button I would like a particular cell in that row to switch to edit mode. For reference here's what the specific column template looks like:
columns.Template(t => { }).HeaderTemplate("")
.ClientTemplate(#"
<a href='javascript: void(0)' class='abutton SecondaryActiveBtn' onclick='editVariableRate(this)' title='Edit'>Edit</a>")
.Width(100).Title("");
Here is the particular javascript method that gets called on the button click:
function editVariableRate(element) {
grid = $("#variableFee").data("kendoGrid");
var cell = $(element).closest("tr").find("td:eq(2)");
grid.editCell(cell);
}
Am I doing something wrong here because the particular column never goes into edit mode?
For reference, I can do the following successfully using the same "cell" variable:
var cellIndex = grid.cellIndex(cell);
and cellIndex gets assigned correctly, so I don't think its a problem of selecting the particular cell...
Anybody have any ideas?
Figured it out! It was the link that was the cause of the problem :( Swapping that to be an input button was the only thing that was needed. bangs head into desk.

Hope this is clear.
I have a view that includes a grid with an existing application. The grid needs to load only after selecting some other inputs in the view. Using one of the "template" approaches like the above example works if you know what the list will contain ahead of time. The grid databinds when the view is rendered, and any ClientTemplate is rendered then. So, rebinding the grid doesnt seem to affect the dropdownlist since it has already been rendered.
However, the contents of the dropdownlist cant be known until the user starts adding items to the grid, so its only then that I to need define whats going to be in the dropdownlist, not from the very beginning when the grid is initially displayed.
How do I define or populate the dropdownlist when the grid is binding or as a result of the read action?
[update]
This is the grid column in question, where now Ive setup the column to have its own datasource, but the action GetSystemItemCodes never gets invoked. There is a read action on the grid itself (not shown), but since the template has already rendered when the grid is displayed the first time, it doesnt matter what I do to update the viewdata, its already been rendered.
columns.Bound(rdetail => rdetail.ItemCode).Title("Item Code").ClientTemplate((#Html.Kendo().DropDownList()
.DataSource(datasrc => datasrc.Read(read => read.Action("GetSystemItemCodes", "SalesVoucher")))
.HtmlAttributes(new { id = "itemCodeDropDown" })
.OptionLabel("- Select Item Code - ")
.DataValueField("ItemCodeID")
.DataTextField("ItemCodeValue")
.Name("itemCodeDropDown")
.Events(e => e.Change("OnItemCodeChange"))
.ToClientTemplate()).ToHtmlString()).Width(230);
I think my next approach will be to filter the dropdown with items being returned when adding a new row.
So suppose my question is at this point is: when defining a datasource for an individual column this way, when does its read action get called? Right after the read action on the grid ? How manually cause the column datasource to refresh or rebind?
I am using Kendo UI Grid master detail template like in this docs http://demos.telerik.com/kendo-ui/grid/angular , I am able to get the template by clicking in the hierarchy cell, I want to know if there is some easy way to expand the detail template by clicking anywhere on row.
Thanks!
To do that you can follow these steps:
Add k-on-change="handleChange(kendoEvent)" to trigger the function when we select any row,
dont forget to add k-rebind="gridOptions.selectable",
and i also prefer <div kendo-grid="grid"></div> so later on we can
select the grid instance
create $scope.handleChange = function(kendoEvent){....}to handle the event
and finally here is a kendo dojo example from yours that i've modified
EDIT:
As per your comment, you simply close all expanded row first then you can open the one which is selected. Add this $scope.grid.collapseRow($scope.grid.tbody.find("tr.k-master-row")); before $scope.grid.expandRow($scope.grid.tbody.find("tr.k-master-row.k-state-selected"));. Updated dojo
I'm using Telerik Kendo UI Professional. I have a grid with an edit template, and several controls on it. I ran into a weird little requirement, where I needed to programmatically set the value of one of the controls, based on another control being changed. The actual change of value seems to happen just fine. However, when I submit the form to save changes, the new, programmatically-set value is ignored; it sends the original value instead. If the user changes the value himself, the new value is submitted just fine.
Here is a sample:
http://dojo.telerik.com/#wittca/otoxO
This is not my original code, but it shows the same problem. In this version, upon opening the edit popup, I programmatically modify the value of the UnitsInStock KendoNumericTextBox. Then when I save the form, I would expect to see the new value, but I still see the old value in the grid. So it does not take the programmatically-generated new value.
My original code is trying to set the value of a KendoComboBox, when one of the other controls changes, and the same situation happens. I didn't have time to create the exact same situation, but most likely if we can fix that dojo sample, the same fix would apply to my ComboBox.
Here is the response I got from Telerik support:
You will need to trigger the change event as well, as the Grid listens for it in order to update the value. Please see the updated example here:
http://dojo.telerik.com/UjUkE
var units = e.container.find("[name='UnitsInStock']").data("kendoNumericTextBox");
units.value( <insert new value here> );
units.trigger("change");
The key line of code is that last one; that manually triggers the "change" event on the control, which forces the Grid to update the value.
This fix also works with my original problem involving ComboBoxes.
He is a solution for you:
If you change the edit function that you have from:
edit: function (e) {
var units = e.container.find("[name='UnitsInStock']").data("kendoNumericTextBox");
var unitsValue = units.value();
units.value(unitsValue+1);
}
to this:
edit: function (e) {
var val = e.model.UnitsInStock;
e.model.set("UnitsInStock", val+ 1);
}
It will bind the updated value for you.
Here is my updated code for you to test:

I have created JQGrid.
I have put the Data in cell and one html Link in cells.
OnClick of that link I need to open JQGrid Specific popUp.Popup have one combobox .I'll select one option and click submit button and that data needs to be appear in clicked cell.
Thanks
The construction which you suggest seems me too complex. Probably you can consider to use more simple user interface?
Nevertheless you can just use setCell method to set new contain of the cell of the grid.
I have an MVC 3 Razor Telerik grid. I have an Edit comand on the row.
When a user clicks on Edit (this places the grid in Edit mode with an Update and Cancel button), I want to set a property for two of the columns to readonly.
When the user clicks on Cancel or Update, I want to set the columns back to full permission.
I know there must be some properties in the controller I should be able to set when the Edit button is pressed for this, but have not seen any docs on how to accomplish this.
How can I do this?
I'm using version 2011.2.712.340 of the controls.
What your describing above sounds a little bit confusing. The purpose of the readonly property is to ensure that when your row enters edit mode the columns that had readonly explicitly set cannot be edited, which seems to be what you're looking for. When in regular read mode all columns will have the same permission whether or not readonly was set, since you are just viewing the data and not editing.
Edit after clarification from comment:
Seems like you want to have this field editable when you are inserting a record, but not when you edit the row. Well, this can be done using some JavaScript. If you use Ajax binding (the only way to fire this event) you can do the following by subscribing to the onEdit client-side event:
...
.ClientEvents(clientEvents => clientEvents.OnEdit("onEdit"))
...
And here's the JavaScript:
<script type="text/javascript">
function onEdit(e) {
var form = e.form;
var mode = e.mode;
if (mode == "edit") {
var country = form.Country; //Country is a public property of my Model
country.disabled = true;
}
}
As you can see above, I get the form with the associated edited row and specifically grab the field associated with the property I do not want to be edited and disable that input element.
