[Solved] Problem with Datagrid_CellCheckBoxClick event?

[The GridLock]

I have a datagrid, after databinding with datatable, I can view my data from the table (it contains checkbox column).

I want to be able to work directly with the checkbox column (meaning I will click directly on the checkbox without selecting the row), I have used this event to determine if the checkbox is checked:

private void sfDataGrid1_CellCheckBoxClick(object sender, CellCheckBoxClickEventArgs e)

{

    if (e.Column.HeaderText == "myCheckboxColumnName" && e.NewValue == Windows.Forms.CheckState.Checked)

    {

     ......

    }

}

However, if the datarow is not selected: e.newvalue will not return a value determine checkbox checked. meaning I always have to select the row before clicking on the checkbox.

What do I need to do to retrieve data just by clicking the checkbox.

My mistake when not using: e.OldValue != Windows.Forms.CheckState.Checked :((

private void sfDataGrid1_CellCheckBoxClick(object sender, Syncfusion.WinForms.DataGrid.Events.CellCheckBoxClickEventArgs e)
        {
            var dataRowView = e.Record as DataRowView;
            if (e.Column.HeaderText == "Priority" && e.OldValue != CheckState.Checked)
            {
                dataRowView.Row[1] = true;
            }
            else
            {
                dataRowView.Row[1] = false;
            }
        }

This is not working.

Thanks,

Hi The GridLock,

Thank you for sharing the code snippet with us.

We have reviewed your code snippet and your requirement. Your goal is to determine the status of the checkbox (checked or unchecked) when directly interacting with it.

In the CellCheckBoxClick event, the event argument includes a NewValue property, which reflects the new state of the checkbox after the click. However, in the provided code snippet, you are checking the old value instead. To achieve your requirement, you can use the NewValue property to retrieve the current state of the checkbox.

Code snippet:

 private void SfDataGrid1_CellCheckBoxClick(object sender, Syncfusion.WinForms.DataGrid.Events.CellCheckBoxClickEventArgs e)

 {

     var dataRowView = e.Record as DataRowView;

     if (e.Column.HeaderText == "Is Delivered" && e.NewValue == CheckState.Checked)

     {

         dataRowView.Row[1] = true;

     }

     else

     {

         dataRowView.Row[1] = false;

     }

 }
