if您只想显示过滤的行,使用 BindingSource.Filter

以下是 msdn 中的一个很好的示例/ p>
bindingSource.Filter =columnname ='value';
private void button1_Click(object sender,EventArgs e)
{
string searchValue = textBox1.Text;
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
bindingSource.Filter = string.Format({0} ='{1}',YourColumnName,searchValue);
//如果您需要
过滤器使用以下
bindingSource.RemoveFilter();
//或
bindingSource.Filter = null;
i have a question regarding with this code, i use a bindingsource to show the data and this code only select the row when im searching in datagridview. i want to know how can i filter the data im searching.
private void button1_Click(object sender, EventArgs e)
{
string searchValue = textBox1.Text;
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
try
{
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (row.Cells[2].Value.ToString().Equals(searchValue))
{
row.Selected = true;
break;
}
}
}
catch (Exception exc)
{
MessageBox.Show(exc.Message);
}
}
解决方案
if you want to display only the filtered rows use BindingSource.Filter
property.
Here is a good sample in msdn
bindingSource.Filter = "columnname = 'value'";
private void button1_Click(object sender, EventArgs e)
{
string searchValue = textBox1.Text;
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
bindingSource.Filter = string.Format("{0} = '{1}'","YourColumnName", searchValue );
//here you can do selection if you need
}
To remove filter use the following
bindingSource.RemoveFilter();
//or
bindingSource.Filter = null;
