我正在使用ASP.NET制作考试Web应用程序。我正在使用网格视图来显示问题和可能的答案。我设置的网格视图大小为1，因此它只在页面索引上显示一个问题。我正在使用单选按钮进行多项选择。
当我选择单选按钮并转到网格视图的下一个问题或下一页索引并再次回到上一个问题时，我看到我之前选择的单选按钮未被选中。我该怎么做？

答案 0 :(得分：0)
使用代码在View-state中保存答案 if（e.CommandName ==“Save”） { foreach（GridView1.Rows中的GridViewRow行） {
if (((RadioButton)row.FindControl("RadioButton1")).Checked)
{
Label12.Text = "A";
}
if (((RadioButton)row.FindControl("RadioButton2")).Checked)
{
Label12.Text = "B";
}
if (((RadioButton)row.FindControl("RadioButton3")).Checked)
{
Label12.Text = "C";
}
if (((RadioButton)row.FindControl("RadioButton4")).Checked)
{
Label12.Text = "D";
}
string m = Convert.ToString（e.CommandArgument）;
ViewState[m] = Label12.Text;
}
在GridView1的Row Data Bound事件中运行for循环 protected void GridView1_RowDataBound（object sender，GridViewRowEventArgs e） {
if (e.Row.RowType == DataControlRowType.DataRow)
{
string id = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "id"));
int i, j;
for (i = 1; i <= 65; i++)
{
j = i + 100;
string k = i.ToString();
string l = j.ToString();
if (ViewState[l] != null)
{
if (id == k)
{
if (ViewState[l].ToString() == "A")
{
(e.Row.Cells[0].FindControl("RadioButton1") as RadioButton).Checked = true;
}
if (ViewState[l].ToString() == "B")
{
(e.Row.Cells[0].FindControl("RadioButton2") as RadioButton).Checked = true;
}
if (ViewState[l].ToString() == "C")
{
(e.Row.Cells[0].FindControl("RadioButton3") as RadioButton).Checked = true;
}
if (ViewState[l].ToString() == "D")
{
(e.Row.Cells[0].FindControl("RadioButton4") as RadioButton).Checked = true;
}
}
}
}
}
}
解决!!!!!
