C# Make other button column cell unclickable when one of the cell is clicked-CodePudding

I had a GUI that have a datagridview with button column.

I set the button enabled property to false once I click on the button cell.

        private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {                 
            DataGridView senderGrid = (DataGridView)sender;
            if (senderGrid.Columns[e.ColumnIndex] is DataGridViewButtonColumn && e.RowIndex >= 0)
            {
                //....
               DataGridViewDisableButtonCell btnClick = (DataGridViewDisableButtonCell)dataGridView4.Rows[e.RowIndex].Cells[e.ColumnIndex];
               btnClick.Enabled = false;
        
               //execude code
        
               btnClick.Enabled = true;
             }                                   
        }

My question is how I make the other cell unclickable also to prevent the code run when one of the button cell is clicked?

CodePudding user response：

You need to get the cells of type DataGridViewDisableButtonCell to get or set their properties. To avoid repeating the same code, create a method to toggle the Enabled property.

private void SetEnabled(bool enabled)
{
    foreach (var cell in senderGrid.Rows.OfType<DataGridViewRow>()
        .SelectMany(x => x.Cells
        .OfType<DataGridViewDisableButtonCell>())) 
        cell.Enabled = enabled;
}

In case you have multiple columns of that type and you want to apply the change on a specific one, then you need to specify the target column:

private void SetEnabled(bool enabled, int columnIndex)
{
    foreach (var cell in senderGrid.Rows.OfType<DataGridViewRow>()
        .SelectMany(c => c.Cells
        .OfType<DataGridViewDisableButtonCell>()
        .Where(col => col.OwningColumn.Index == columnIndex)))
        cell.Enabled = enabled;
}

Using the method in your code:

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    var senderGrid = sender as DataGridView;

    if (senderGrid.Columns[e.ColumnIndex] is DataGridViewButtonColumn && e.RowIndex >= 0)
    {
        SetEnabled(false);
        // Or
        // SetEnabled(false, e.ColumnIndex);

        //execude code

        SetEnabled(true);
        // Or
        // SetEnabled(true, e.ColumnIndex);
    }
}
