问题描述
我想做一个调查。在我的项目中，我有一个问题。那就是;
GridView中的RadioButtonList和ListItem在GridView1_PageIndexChanging子中工作;当我点击页面底部的
下一步按钮时，它不会保留
用户选择。它要么保留-1（没有选择），要么在GridView1_PageIndexChanging事件期间将它设置为它。
I want to do a survey. In my project , I have a problem. That is;
RadioButtonList AND ListItem in gridview dosent work in GridView1_PageIndexChanging sub; when I click a
"next button" on the bottom of the page, it is not retaining the
users selection. It either retains -1 (no selection), or whatever I
set it to during the GridView1_PageIndexChanging event.

<asp:radiobuttonlist id="rblChoices" runat="server" repeatdirection="Horizontal" onselectedindexchanged="rblCategories_SelectedIndexChanged" autopostback="True" xmlns:asp="#unknown">
</asp:radiobuttonlist>
then
then
protected void rblCategories_SelectedIndexChanged(object sender, EventArgs e)
{
var listControl = (ListControl)sender;
var row = (GridViewRow)listControl.NamingContainer;
var item = listControl.SelectedItem;
Label anketid = (Label)row.FindControl("Label16");
Label userid = (Label)row.FindControl("Label17");
Label soruid = (Label)row.FindControl("Label18");
try
{ label20.Text= item.Text /Radio Button Selected Value
// BusinessLayer.UserAnketKaydet(Convert.ToInt16(anketid.Text), Convert.ToInt16(soruid.Text), Convert.ToInt16(item.Text), Convert.ToInt16(userid.Text));
}
catch
{
}protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.SelectedIndex = -1;
BindGrid(); // Call bind here
