objDs.DataSource = dv;
objDs.AllowPaging = true;

dlQuestions.DataBind();
}
protected void cmdNext_Click1(object sender, EventArgs e)

try

CurrentPage += 1;
itemsGet();
}
catch (Exception ex)

}
}
protected void cmdPrev_Click(object sender, EventArgs e)
{
try
{
CurrentPage -= 1;
itemsGet();
}
catch (Exception ex)
{
}
}
protected void dlQuestions_ItemCommand(object source, DataListCommandEventArgs e)
{
foreach (DataListItem item in dlQuestions.Items)
{
RadioButton RB = item.FindControl("rdb1") as RadioButton;
if (RB != null && RB.Text != null)
{
lblanswer.Text= RB.Text;//for testing purpose only
}
}
}
}
推荐答案
protected void dlQuestions_ItemCommand(object source, DataListCommandEventArgs e)
{
RadioButton RB = (RadioButton)e.Item.FindControl("rdb1");
if (RB != null && RB.Text != null)
{
lblanswer.Text = RB.Text;//for testing purpose only
}
}
