Get value of DataGridViewCheckBox

[ralphtrent]

Hello
I have a datagridview which containts a checkbox column. I need to konw what the value is of the checkbox in order to enable or disable a button. it seems like any events I try to capture this with is too early.

id offer code, but lets just say I scrapped it all

Any help is appreciated.

I use this method to get a button in a gridview, should be much the same for a checkbox, let see...

<script runat="server">
  void chkBox1_CheckChanged(object sender, EventArgs e)
  {
    CheckBox cb = (CheckBox)sender;
    GridViewRow grdRow = (GridViewRow)cb.Parent.Parent;
    //get the row that was clicked
    int index = Convert.ToInt32(grdRow.RowIndex);
    //find the control by name and index
    CheckBox myCheckBox = (CheckBox)grdProducts.Rows[index].FindControl("<CONTROL NAME>");
        }
</script>

Hope this helps,

Patrick

Hi Patrick, thanks for the reply. I should have mentioned that this was for a WinApp, not a Web App. But from looking at your code, it looks like you are referring to a CheckBox control and putting an event wrapper around it. I thought that might work regardless of interface since i do have a System.Windows.Forms.DataGridViewCheckBoxColumn() controls on the page that is used to create the checkbox feature, however, there are not events other then dispose for this control.

I think I need to react to an event for the datagridview itself.

Any idea's?

Thanks again.

I figured it out:

private void dgvResults_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
	if (dgvResults.CurrentCell.ColumnIndex == 0)[green]//My checkbox is column 0[/green]

        {
		dgvResults.CommitEdit(DataGridViewDataErrorContexts.Commit);
	}
}

private void dgvResults_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
	if (e.ColumnIndex == 0) [green]//My checkbox is column 0[/green]
        {
        	setDeleteFolderStatus();
	}
}

private System.Collections.Generic.List<DataGridViewRow> getCheckedRows()
{
	System.Collections.Generic.List<DataGridViewRow> gdgvrReturn = new System.Collections.Generic.List<DataGridViewRow>();
        foreach (DataGridViewRow dgvr in dgvResults.Rows)
        {
        	if (dgvr.Cells[0].Value != null)
                {
			if (((DataGridViewCheckBoxCell)dgvr.Cells[0]).Value.Equals(true))
			{
				gdgvrReturn.Add(dgvr);
			}
		}
	}
	return gdgvrReturn;
}
