Hello,

Do you mean selecting multiple cells?

May I ask what is the goal of selecting multiple cells in your case?

[Alr1976]

I need to insert tasks to be done in multiple cells at the same time. I can't use cell by cell, it's not user friendly.

[Sherzod]

I will try to check. 

[Sherzod]

Do you mean selecting a continuous range of cells (like in Excel), or selecting individual cells separately using Ctrl+Click?

[Alr1976]

If possible, I would like to implement both options. If that's not possible, at least one of the two options.

Hello,
I understand your interest in getting a quick solution, and we all try to help each other here as much as possible. However, please keep in mind that not all questions get an instant or complete answer on the forum. Sometimes it takes time and effort to find or test a working solution.

For your first scenario (selecting a range of cells), I recommend checking this post:

You can analyze how to get the selected cells, but you will need to do some additional research and adjustments to fully implement the required logic.

For the second scenario (selecting arbitrary cells), you can analyze the cellclick event, and try to add/remove a custom selection class on click. Later, you can collect all selected cells by their class name.
These are just some hints to point you in the right direction.

Hope this helps a bit.

ok, I need to know RangeSelection. How to implement it?

i tried:

function selectionchange(model, selected, eOpts) {
  // 'model' è il SelectionModel. La griglia è accessibile tramite la sua view.
  // Questo è il metodo più affidabile per ottenere il riferimento alla griglia.
  var grid = model.view.ownerGrid;

  // Se 'grid' fosse ancora undefined, un'alternativa è usare il parametro 'selected'.
  // L'oggetto 'selected' (Ext.grid.selection.Cells) ha un riferimento al suo selModel.
  if (!grid && selected && selected.view) {
      grid = selected.view.ownerGrid;
  }

  // Se dopo entrambi i tentativi la griglia non è definita, usciamo per sicurezza.
  if (!grid) {
      console.error('uniGUI Error: Could not get a reference to the grid.');
      return;
  }

  // Controlliamo che 'selected' sia un oggetto di selezione celle valido.
  if (!selected || !selected.isCells) {
    ajaxRequest(grid, 'cellSelection', ['[]']);
    return;
  }

  var cells = selected.getCells();
  var selectedData = [];
  var store = grid.getStore();
  var columns = grid.getColumns();

  for (var i = 0; i < cells.length; i++) {
    var cellCoord = cells[i];
    var rowIndex = cellCoord[0];
    var colIndex = cellCoord[1];
    
    if (rowIndex < store.getCount() && colIndex < columns.length) {
      var record = store.getAt(rowIndex);
      var fieldName = columns[colIndex].getDataIndex();
      var cellValue = record.get(fieldName);

      selectedData.push({
        row: rowIndex,
        col: colIndex,
        value: cellValue
      });
    }
  }

  var jsonData = Ext.JSON.encode(selectedData);
  ajaxRequest(grid, 'cellSelection', [jsonData]);
}

 

But doesn' t works

tks,Alessandro
