Question

根据(下拉框 文本)的值 在Gridview中显示对应信息 该怎么实现呢？

return

Answer 1

下拉框的值发生改变的时候获取下拉框的值,然后根据那个值读取你要的信息,
再填充到Gridview

如: private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
textBox1.Text = comboBox1.Text;
}

Answer 2

private void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
//绑定Gridview
}
注意要启用ddl的outpostback属性
如果想要页面不刷新可以考虑加上ajsx的UpdatePanel

Answer 3

protected void DropDownList1_SelectedIndexChanged(object sender, System.EventArgs e)
{
if(DropDownList1.Items[0].Selected)
{
GridView1.DataSource = ds.Tables[0];
GridView1.DataBind();
}
else if(DropDownList1.Items[1].Selected)
{
GridView1.DataSource = ds.Tables[1];
GridView1.DataBind();
}
