Create Grids with Dynamic Columns and Data Types
The following example demonstrates how to create a Grid with column and data-field information that is retrieved during runtime.
<div id="grid" style="width:1000px;"></div>
<script>
var isDateField =[];
$.ajax({
url: "https://www.mocky.io/v2/5835e736110000020e0c003c",
dataType: "jsonp",
success: function(result) {
generateGrid(result);
}
});
function generateGrid(response) {
var model = generateModel(response);
var columns = generateColumns(response);
var grid = $("#grid").kendoGrid({
dataSource: {
transport:{
read: function(options){
options.success(response.data);
}
},
pageSize: 5,
schema: {
model: model
}
},
columns: columns,
pageable: true,
editable:true
});
}
function generateColumns(response){
var columnNames = response["columns"];
return columnNames.map(function(name){
return { field: name, format: (isDateField[name] ? "{0:D}" : "") };
})
}
function generateModel(response) {
var sampleDataItem = response["data"][0];
var model = {};
var fields = {};
for (var property in sampleDataItem) {
if(property.indexOf("ID") !== -1){
model["id"] = property;
}
var propType = typeof sampleDataItem[property];
if (propType === "number" ) {
fields[property] = {
type: "number",
validation: {
required: true
}
};
if(model.id === property){
fields[property].editable = false;
fields[property].validation.required = false;
}
} else if (propType === "boolean") {
fields[property] = {
type: "boolean"
};
} else if (propType === "string") {
var parsedDate = kendo.parseDate(sampleDataItem[property]);
if (parsedDate) {
fields[property] = {
type: "date",
validation: {
required: true
}
};
isDateField[property] = true;
} else {
fields[property] = {
validation: {
required: true
}
};
}
} else {
fields[property] = {
validation: {
required: true
}
};
}
}
model.fields = fields;
return model;
}
</script>
