DataGridView Default Row/Cell select issue

Question

DataGridView set to Full Row Select. Need a way to clear the default selected row thats done by the default nature of DataGridView

I am also using SelectionChanged event That dgv has 4 columns

If i leave the default row selection, SelectionChanged fires 4 times when its loaded which I don't want it to fire at all.

I have tried using the RowsPostPaint event which clears the selection and doesn't fire the SelectionChanged event but i'm unable to select any rows after.

Any ideas? Thanks

Answer 1

use this

in form loading:

     datagridview.DataBindingComplete += new DataGridViewBindingCompleteEventHandler(datagridview_DataBindingComplete);

and for the listener:

    private void datagridview_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
    {
        datagridview.ClearSelection();
    }

bute note that anytime you change datasource your default selection hides.

Answer 2

After populating datagrid,try this one.

datagrid.ClearSelection();

To de-select the initial row selection, you can enumerate the SelectedRows and set the Selected property to false . To prevent the SelectionChanged event from firing when the initial row is selected, add the event manually, after you de-select it.

For example, in the form's Load event:

foreach(DataGridViewRow row in dataGridView1.SelectedRows)
    row.Selected = false;

dataGridView1.SelectionChanged += dataGridView1_SelectionChanged;
