Hello, I have the above form where it shows all the products that I have registered in my database and presents in a Gride.
I placed the checkbox inside this Gride. I would like you to only record items that are checked out of the checkbox. How can I do this?
DataGridViewCheckBoxCell cell;
foreach (DataGridViewRow linha in dgView.Rows)
{
cell = linha.Cells["nome da coluna (ou o índice)"] as DataGridViewCheckBoxCell;// linha.Cells["nomeDaColuna"] ou linha.Cells[0]
bool bChecked = (null != cell && null != cell.Value && true == (bool)cell.Value);
if (bChecked)
{
}
}
You need to go through all lines in DataGridView and check that CheckBox is checked, this way
foreach(DataGridViewRow linha in dgView.Rows){ // passar por todas as linhas do dg
var cell = linha.Cells["ColunaDoCheckBox"] as DataGridViewCheckBoxCell; //pegar a celula que tem o checkbox
if((bool)cell.Value){ //verificar se está marcado
//salvar registro
}
}
An example of how to get checked values in checkbox :
List<int> codigos = new List<int>();
if (bool.Parse(DataGridView.CurrentRow.Cells[2].FormattedValue.ToString()) == true)
{
foreach (DataGridViewRow check in DataGridView.Rows)
{
if ((bool)check.Cells[2].FormattedValue)
{
b = int.Parse(check.Cells[0].Value.ToString());
}
}
codigos.Add(b);
}
else
MessageBox.Show("Selecione um item");
Returns the codes of the selected items in checkbox .
