Hi,

Below is the beginning of the kendo grid and its template.

@(Html.Kendo().Grid<CompanyDomainView>()
    .Name("customer-grid")
    .ClientDetailTemplateId("customerTemplate")
    ........

<script id="customerTemplate" class="gridtemplates" type="text/x-kendo-tmpl">
    <section>
        <div class="k-widget inline-grid-box">
.....

The template have a SAVE and a CANCEL button and I have problem with the CANCEL button.
When the user makes some changes and hit the cancel button, the template content should go back and show its previous data.

I don't want to refresh all the controls in the template in code, just to remove current instance of the template from the kendo-list of created templates.
I am able to programmatically collapse and expand any row in the grid, but I don't know how to instruct kendo to forget a template.

Think this: I collapse the row, remove its created template and expand the row again and a fresh template with data from its parent (the row).
How can i do that ?
Thanks.

Hello,

The grid will reinitialize the detail if you remove the detail row so you could use logic similar to the one in the snippet below in the click handler:
function onCancelClick() {
    var detailRow = $(this).closest(".k-detail-row");
    var masterRow = detailRow.prev();
    var grid = $("#customer-grid").data("kendoGrid");
    grid.collapseRow(masterRow);
    kendo.destroy(detailRow);
    detailRow.remove();
    grid.expandRow(masterRow);
}

Hi Daniel and thanks.

I see there are a lot of things I don't know anything of :-)

Below is my cancel-test.
There are three steps in the code. 1:Find the MODEL and cancel the changes, 2:Replace the row with the old data, 3:select and expand the template again + deactivating the buttons.

function TEST_CancelChanges(ItemID, uid) {
    try {
        kendo.ui.progress($("#" + gridname), true);
        var grid = $("#" + gridname).data("kendoGrid");
        var model = grid.dataSource.get(ItemID);
        grid.dataSource.cancelChanges(model);
 
        var row = grid.items().filter("[data-uid=" + uid + "]");
        var template = row.hasClass("k-alt") ? grid.altRowTemplate : grid.rowTemplate;
        var tmp = $(template(model));
        row.replaceWith(tmp);
 
        if (expandedRowUid != null) {
            $('[data-uid=' + expandedRowUid + ']').addClass('k-state-selected');
            expandItem(expandedRowUid);
            ActivateTemplateButtons(expandedRowUid, false);
        }
    }
    finally {
        kendo.ui.progress($("#" + gridname), false);
    }
}

From your code, I see you find the detailrow and destroy + remove it.
Where would that fit into the sample above (please feel free to change the sample code) ??
Thanks.

Hi again,

You can execute the logic before replacing the row:
var detailRow = row.next(".k-detail-row");
if (detailRow.length) {
    grid.collapseRow(row);
    kendo.destroy(detailRow);
    detailRow.remove();
}
row.replaceWith(tmp);
Otherwise, you should find the row for the model again or use replaceAll instead of replaceWith so that you have a reference to the new row.
