反映新的约束力

问题描述：

加载数据集已填充且数据源已设置为表格。

On Load the Dataset is filled and the datasource set to the table.

接下来在函数中另一个已过滤table in created并绑定到datagridview。

Next in a function another filtered table in created and bound to the datagridview.

但它只会更改视图，仍然单击它会打开旧行，前一个绑定索引。

But it only changes the view , still on click it opens the old row, previous binding index.

我还申请了

dataGridView1.Update（）;

dataGridView1.Refresh（）;

dataGridView1.Update();
dataGridView1.Refresh();

我还设置了

dataGridView1.DataSource = null;

然后我绑定新表dataGridView1.DataSource = ds.Tables [0];

Then I bind new table dataGridView1.DataSource = ds.Tables[0];

但在给定的索引处，它仍会打开第一个绑定的旧行。

But at the given index it still opens the old row from the first binding.

答

尝试清除数据集然后重新将一些数据添加到数据集中：

Try to clear the dataset then re-add some data to the dataset:

        private DataTable dt = new DataTable();
        private DataSet ds = new DataSet();

        private void button1_Click(object sender, EventArgs e)
        {
            ds.Clear();
            adapter.Fill(ds);//re-fill dataset yourself
            dt = ds.Tables[0];
            dataGridView1.DataSource = dt;
        }

问候，

Frankie
