Hey Guys,

I''ve been looking for a solution to apply multiple filtration using text boxes and showing the result in Data grid view. This data is imported form SQL Server and p-printed to datagridview.

Thanks and Regards

推荐答案

//Create a binding source
BindingSource bindingSource1 = new BindingSource();
//Set the datasource property of bindingsource to the DataSet
bindingSource1.DataSource = NorthWindDataset1;
//Set the DataMember property to the required DataTable
bindingSource1.DataMember="Customers";
//Set the DataSource property of DataGridView to the BindingSource
dataGridView1.DataSource = bindingSource1;

//Create a button and in the Click event of button insert the following code
//Now to apply multiple filter, create a filter string based on the data of the text boxes
string filterString = string.Format("CustomerID='{0}' and City='{1}' and Region='{2}",textBox1.Text.Trim(), textBox2.Text.Trim(), textBox3.Text.Trim());
//set the filter of bindingSource1
bindingSource1.Filter=filterString;
