checkbox,button,imagebutton使用dataGridView1_CellContentClick
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
tb.Text+=string.Format("\r\n{0}，Row:{1}，Column:{2}","单元格内容单击！",e.RowIndex,e.ColumnIndex);
}
combobox使用EditingControlShowing+DropDownClosed，此二事件结合使用可以做到内置combobox一下拉选择了就触发事件
private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
tb.Text += string.Format("\r\n{0}，控件名:{1}", "单元格控件编辑！", e.Control.GetType());
if (e.Control.GetType().Equals(typeof(DataGridViewComboBoxEditingControl)))
{
DataGridViewComboBoxEditingControl editingControl = e.Control as DataGridViewComboBoxEditingControl;
try
{
editingControl.DropDownClosed -= new EventHandler(editingControl_DropDownClosed);
}
catch
{
}
editingControl.DropDownClosed += new EventHandler(editingControl_DropDownClosed);
}
else if (e.Control.GetType().Equals(typeof(DataGridViewTextBoxEditingControl)))
{
DataGridViewTextBoxEditingControl editingControl = e.Control as DataGridViewTextBoxEditingControl;
try
{
}
catch
{
}
}}
private void editingControl_DropDownClosed(object sender, EventArgs e)
{
DataGridViewComboBoxEditingControl ctl = sender as DataGridViewComboBoxEditingControl;
int r = dataGridView1.CurrentCell.RowIndex;
int c = dataGridView1.CurrentCell.ColumnIndex;
tb.Text += string.Format("\r\n{0}，控件名:{1}", "单元格下拉框下拉！", ctl.GetType());
dataGridView1.CellValueChanged -= dataGridView1_CellValueChanged;
}
textbox一般只需要验证事件可使用dgvJointList_CellValidating
private void dgvJointList_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
int r = dgvJointList.CurrentCell.RowIndex;
int c = dgvJointList.CurrentCell.ColumnIndex;
if (dgvJointList.Columns["diameter"].Index == c ||
dgvJointList.Columns["thickness"].Index == c ||
dgvJointList.Columns["weldLength"].Index == c)
{
string txt = dgvJointList.CurrentCell.EditedFormattedValue.ToString();
string errorMsg;
if (!ValidNumericFF(txt, out errorMsg))
{
e.Cancel = true;
this.errorProvider1.SetError(dgvJointList, errorMsg);
}
else
{
this.errorProvider1.SetError(dgvJointList, "");
}
}
}
