سلام
اگه از BindingSource استفاده کنی می تونی خیلی راحت با استفاده از خاصیت Filter اون جستجو رو انجام بدی.
private void PopulateDataViewAndFilter()
{
DataSet set1 = new DataSet();
// Some xml data to populate the DataSet with.
string musicXml =
"<?xml version='1.0' encoding='UTF-8'?>" +
"<music>" +
"<recording><artist>Coldplay</artist><cd>X&Y</cd></recording>" +
"<recording><artist>Dave Matthews</artist><cd>Under the Table and Dreaming</cd></recording>" +
"<recording><artist>Dave Matthews</artist><cd>Live at Red Rocks</cd></recording>" +
"<recording><artist>Natalie Merchant</artist><cd>Tigerlily</cd></recording>" +
"<recording><artist>U2</artist><cd>How to Dismantle an Atomic Bomb</cd></recording>" +
"</music>";
// Read the xml.
StringReader reader = new StringReader(musicXml);
set1.ReadXml(reader);
// Get a DataView of the table contained in the dataset.
DataTableCollection tables = set1.Tables;
DataView view1 = new DataView(tables[0]);
// Create a DataGridView control and add it to the form.
DataGridView datagridview1 = new DataGridView();
datagridview1.AutoGenerateColumns = true;
this.Controls.Add(datagridview1);
// Create a BindingSource and set its DataSource property to
// the DataView.
BindingSource source1 = new BindingSource();
source1.DataSource = view1;
// Set the data source for the DataGridView.
datagridview1.DataSource = source1;
//The Filter string can include Boolean expressions.
source1.Filter = "artist = 'Dave Matthews' OR cd = 'Tigerlily'";
}
