如何通過關鍵字過濾datagridview？

Question

我想在C＃和DataGridView的訪問文件中搜索Textbox的關鍵字，我的代碼在下面，但有錯誤「缺少操作數」的問題;

BindingSource bs = new BindingSource(); 
bs.DataSource = dataGridView1.DataSource; 
bs.Filter = "select * FROM book WHERE onvan like '*" + textBox1.Text + "*'"; 
dataGridView1.DataSource = bs; 

Answer 1

您無法將完整的選擇查詢作爲您的bindingsource的過濾器。試試這個代替

bs.Filter = "onvan like '*" + textBox1.Text + "*'"; 

並檢查此鏈接的更多信息：BindingSource.Filter。
