How to disable selection of cells in ag-grid?

Question

I have a simple ag-grid in an Angular project and want to disable selection of cells in one of its columns. Simply removing the default blue outline during selection would also be fine. I just want no visual change to the cell when the user clicks inside it. How can I do this?

I see that ColDef has a property suppressNavigable that sort of helps, since it disallows using the tab key to select the cells, but it still allows selection by clicking. Also, the grid itself seems to offer suppressCellSelection but it doesn't seem granular enough and doesn't seem to affect anything anyway.

So, how can I remove this blue border cell selection?

Here's the code I have for these column definitions:

this.columnDefs = [
  { headerName: 'One', field: 'one' },
  { headerName: 'Two', field: 'two' },
  { 
    // I want to disable selection of cells in this column
    headerName: 'I want no cell selection!', 
    field: 'three',   
    suppressNavigable: true,
    editable: false,
  }
];

Here's a stackblitz example I was using to test with.

Here's a screenshot of the blue border I don't want to see in this column:

Solution 1

Note that if we set gridOption.suppressCellSelection = true we can disable cell selection for all columns' cells.

Here the question is regarding not showing a specific column's cell's highlighted border when it is selected.

You can achieve this by bit of CSS and cellClass property of ColDef.

You'll need to add below CSS.

.ag-cell-focus,.ag-cell-no-focus{
  border:none !important;
}
/* This CSS is to not apply the border for the column having 'no-border' class */
.no-border.ag-cell:focus{
  border:none !important;
  outline: none;
}

And use the same class as cellClass in ColDef

suppressNavigable: true,
cellClass: 'no-border'

Live example: aggrid-want-to-disable-cell-selection
This won't show border for the cell you even focus using mouse click.

Solution 2

I'd suggest to use the suppressCellSelection option in gridOptions. A CSS quick fix is not something that I'd suggest to go for.

this.gridOptions = {
  // Your grid options here....
  suppressCellSelection: true
};

Solution 3

You can try this css hack. no custom flags needed.

.ag-cell-focus, .ag-cell {
    border: none !important;
}

Solution 4

You can also use cellStyle to remove the selection dynamically. Here is an example:

{
  headerName: "Is Selectable",
  cellStyle: (params) => {
    if (!params.value) {
      return { border: "none" };
    }
    return null;
  },
  ...
},
{
  headerName: "UnSelectable",
  cellStyle: { border: "none" },
  ...
}

I'm glad it helped! It's quick to help when the reproduced issue is shared.

Why not suppressCellSelection in gridOptions?

[Paritosh]

PO just want to disable it for a single column. Not for all column. The issue is styling for the selected cell which is suppressed from navigation

[struppi]

That option is already set in my gridoptions. It doesn't help.

[Marian Simonca]

For me it worked only with ::ng-deep before .no-border.ag-cell:focus. Thanks for your answer!

[xandermonkey]

This prevents the selection in a visible way, but the grid api will still consider the cell selected.

[Paritosh]

@xandermonkey - thats right, but here PO's intention is just regarding the UI aspect of this.

[takanuva15]

How would you prevent cell selection for all columns? Do I have to repeat cellClass for every single header?

[takanuva15]

Nvm, just add ::ng-deep .ag-cell:focus{ border: none !important; outline: none; } to your css

[Joshua Wade]

This only removes the highlight. The keyboard navigation behavior is retained, so you'll get strange behavior with the left and right arrow keys if your table scrolls horizontally.

This post answers the OP's question in that OP said "Simply removing the default blue outline during selection would also be fine". And it does exactly that. Amazing that this got downvoted.

@ChrisFarmer make sure enableRangeSelection is false

Worked from me thanks !!

Amazing, solved 10 problems together for me :D. Only for future visitors: Notice that in newer versions of AG Grid it's been replaced by suppressCellFocus (since v27.0).
