How to prohibit change checkbox(checked/unchecked) by doubleclicking on row?
To prohibit changing the checkbox state by double-clicking on a row, you can handle the double-click event and prevent it from modifying the checkbox. Here's an example using C# and WinForms:
Create an event handler for the double-click event of the row or cell in which the checkbox is located:
csharpprivate void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
// Check if the double-clicked cell is the checkbox cell
if (e.RowIndex >= 0 && e.ColumnIndex == checkBoxColumn.Index)
{
// Prevent the checkbox from changing its state
dataGridView1.EndEdit();
}
}
Assign the event handler to the appropriate event of the DataGridView control. For example, if you want to handle the double-click event for the entire row:
csharpdataGridView1.RowHeaderMouseDoubleClick += dataGridView1_CellDoubleClick;
If you want to handle the double-click event for a specific cell:
csharpdataGridView1.CellDoubleClick += dataGridView1_CellDoubleClick;
In this example, the dataGridView1_CellDoubleClick
event handler is called when a double-click occurs on a row or cell in the DataGridView control. It checks if the double-clicked cell is the checkbox cell (identified by its column index), and if so, it calls EndEdit
to prevent the checkbox from changing its state.
Make sure to adjust the code to match your specific scenario, including the DataGridView control name, checkbox column index, and event assignment.
By handling the double-click event and preventing the checkbox from changing its state, you can prohibit users from modifying the checkbox by double-clicking on the row or cell.
