I added a default value option to ExtInputDialog

[tomandersen]

You can have a pre - populated suggestion:

Example code...
function addToOrder(e) {
var theLine = this.dataItem($(e.currentTarget).closest("tr"));
$.when(kendo.ui.ExtInputDialog.show({
title: theLine.title,
input: "1",
message: "Enter the Order Quantity",
required: true,
initialInput: "1" })
).done(function (response) {
if (response.button == "OK") {
console.log(kendo.format("{0} button clicked with input of: {1} for item {2}", response.button, response.input, theLine.no));
} else {
console.log(kendo.format("{0} button clicked", response.button));
}
});

e.preventDefault();
return false;

}

Changes I made to kendo.web.ext.js - added two lines to the bottom of ExtInputDialog
......
modal: true,
visible: false,
message: "",
required: false,
requiredCss: "k-ext-required",
initialInput: "" // added by Tom Andersen
}, options);

            $(document.body).append(kendo.format("<div id='extInputDialog' style='position:relative;'><div style='display:block;margin-left:10px;right-margin:10px;'>{0}</div><div style='display:block;margin-left:10px;margin-right:15px;'><input type='text' class='k-ext-input-dialog-input' style='width:100%;'</input></div></div>", options.message));
            dialog = $("#extInputDialog").kendoExtDialog(options).data("kendoExtDialog");
            $("#extInputDialog").parent().find("div.k-window-titlebar div.k-window-actions").empty();
            $("#extInputDialog .k-ext-input-dialog-input").val(options.initialInput); // added by Tom Andersen
            dialog.center().open();
