Question

您好，想请教选中treeview上的一个节点后，在dataGridView中显示数据的方法。 在线等，谢谢您。

Answer 1

treeview的nodeclick事件里给datagridview绑定数据就成了呗

Answer 2

前台treeview控件：
<asp:TreeView ID="TreeView1" runat="server" OnSelectedNodeChanged="TreeView1_SelectedNodeChanged1" OnTreeNodeDataBound="TreeView1_TreeNodeDataBound">
</asp:TreeView>
<asp:GridView runat="server" ID="gv"></asp:GridView>
后台方法：
protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{
DataSet ds = new DataSet();
string selectedNodeText = this.TreeView1.SelectedNode.Text;
if (selectedNodeText == "节点1")
{
string ConnString = System.Configuration.ConfigurationManager.AppSettings["DBConnString"];
try
{
string selectUserBasicInfo = "select * from users where name = '" + selectedNodeText + "'";
SqlDataAdapter sda = new SqlDataAdapter(selectUserBasicInfo, ConnString);
sda.Fill(ds);
//GridView gv = new GridView();
gv.DataSource = ds.Tables[0];
gv.DataBind();
}
catch (Exception e)
{
string emsg = e.Message.ToString();
}
}
else if (selectedNodeText == "节点2")
{
//绑定数据
}
else if (selectedNodeText == "节点3")
{
//绑定数据
}
}
