如何在运行时设置过滤器？对于C＃，Winforms，DevExpress中的gridview [英] How to set Filter in run time ? for gridview in C#, Winforms, DevExpress

问题描述

我在运行时附加了新的DataSource和DataSet。我也在运行时设置过滤器，但它显示错误找不到列[invoice_number]



我的代码是

Hi, I attach new DataSource and DataSet on Run Time. I set filter also in the Run Time but it shows error ""Cannot find column [invoice_number]"

my code is

// Create a connection object. 
            OleDbConnection connection = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:/Srihari/OrionSystem.accdb");

            // Create a data adapter. 
            OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM gridview", connection);

            // Create and fill a dataset. 
            DataSet sourceDataSet = new DataSet();
            adapter.Fill(sourceDataSet);

            // Specify the data source for the grid control. 
            gridControl1.DataSource = sourceDataSet.Tables[0];

            invoiceBindingSource.Filter = string.Format("invoice_number = '{0}'", textEdit5.Text);// error show n this line

但我的OrionSystem Access数据库在表gridview中有invoice_number列。我的错误是什么？

but my OrionSystem Access Database having the Column "invoice_number" in the table gridview. What is my error ?

推荐答案

试试这个：

Try This:

DataTable DataTable = null;
DataTable = sourceDataSet.Tables(0);

if (Information.IsDBNull(DataTable) == false) {
	DataView dataView = DataTable.DefaultView;
	dataView.Sort = "invoice_number asc";
	GridView1.DataSource = dataView;
        GridView1.DataBind();
}
