我已经尝试过

I''ve tried

switch (e.Row.RowState)
            {
                case DataControlRowState.Normal:
                case DataControlRowState.Alternate:
                case DataControlRowState.Edit:
                    Label myLabel1 = (Label)e.Row.FindControl("lblProdid");
                    string idField = myLabel1.Text;
                   // string q = DDlQno.SelectedItem.Text;
                    //string idField = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "lblProdid"));
                    GridView rep = (GridView)e.Row.FindControl("GridView1");
                   // rep.DataSource = yourdatasource;
                    rep.DataBind();
                    break;
            }

我已经尝试过

And I''ve tried

f (e.Row.RowType != DataControlRowType.DataRow)
            {
                SqlDataSource s = (SqlDataSource)e.Row.FindControl("obsMeas");
                s.SelectParameters[0].DefaultValue = DDlQno.Text;
                s.SelectParameters["id"].DefaultValue = ((Label)e.Row.FindControl("lblProdid")).Text;
            }

在此先感谢

推荐答案

您可以使用FindControl方法.

试试类似的东西:

You can use FindControl method.

Try something like:

foreach (GridViewRow item in myGrid.Rows)
{   
    Label myLabel = (Label)item.FindControl("lblProdId");
    string text = myLabel.Text;
    //use the text now          
} 

如果您处于gridview事件中，并且已经具有行级访问权限，则:

If you are in a gridview event and already have access at row level then:

Label myLabel = (Label)e.Row.FindControl("lblProdId");
string text = myLabel.Text;
//use the text now  

它应该起作用.

It should work.

您能告诉我们何时需要标签值吗?

can u tell when u want label value ?
