Description

How can I set the width of details column when for each detail level too much space gathers to the right?

Solution

Depending on the theme, the hierarchy column applies a different width. For example, in the new Kendo UI Default SASS theme, the detail column with the expand arrow is 32px.

To change the column with the hierarchy cell, use the following CSS selector to target it.

<style>
  .k-grid .k-hierarchy-col {
    width: 20px;
  }
</style>

The following example demonstrates how to implement the suggested approach.

<style>
      .k-grid .k-hierarchy-col {
        width: 120px;
      }
    </style>
    <div id="grid"></div>
    <script>
      $("#grid").kendoGrid({
        columns: [
          { field: "name" }
        ],
        dataSource: [{
          name: "Beverages",
          products: [{
            name: "Tea",
            brands: [{
              name: "PG tips", distributors: [{name:"Tesco"},{name: "Sainsbury's"}]
            },{
              name: "Lipton", distributors: [{name: "ASDA"}, {name: "Iceland"}]}]
          },{
            name: "Coffee",
            brands: [{
              name:"Lavazza", distributors: [{name: "Coca-Cola"}]
            },{
              name: "Kenco", distributors: [{name: "ASDA"}, {name: "Morrisons"}]}]
          }]},{
            name: "Food",
            products: [{
              name: "Ham", brands: [{ name: "Cook's ham"},{ name: "Honey and mustard breaded ham"}]
            },{
              name: "Bread", brands:[{ name: "KingsMill"},{ name: "Hovis"}]
            }]
          }],
        detailTemplate: 'Products: <div class="second-level-grid"></div>',
        detailInit: function(e) {
          e.detailRow.find(".second-level-grid").kendoGrid({
            dataSource: e.data.products,
            columns: ["name"],
            detailTemplate: 'Brands: <div class="third-level-grid"></div>',
            detailInit: function(e){
              e.detailRow.find(".third-level-grid").kendoGrid({
                dataSource: e.data.brands,
                columns:["name"],
                detailTemplate: 'Distributors: <div class="fourth-level-grid"></div>',
                detailInit: function(e){
                  e.detailRow.find(".fourth-level-grid").kendoGrid({
                    dataSource: e.data.distributors,
                  })
                }
              })
            }
          })
        }
      });
    </script>
