推荐答案

Because u r using loop that is why every time your labels value r replaced by next one so at the last of loop , it contain only values of last row
for (int i = 0; i < dt.Rows.Count; i++)
          {
              lblMaterial.Text = dt.Rows[i][1].ToString();
              lblMaterialValue.Text = dt.Rows[i][0].ToString();
              lblMaterialQty.Text = dt.Rows[i][2].ToString();
          }

告诉你想要什么?

tell what do u want ?

<pre lang="c#">

GridViewObject.DataSource = datatableObject;

绑定后，您可以更改或修改数据.

关于Rahul

GridViewObject.DataSource=datatableObject;

and after binding you can change or modify with data.
