I have a page with a radiobuttonlist and textarea. data is displayed dynamically within the textarea based on the user’s selection. i also set up a OnSelectedIndexChanged=”RadioButtonList1_SelectedIndexChanged” to create a url that will allow users to reference their article (radio button selection).
everything works except for cutting and pasting the created url (i.e. http://test.com/test.aspx?selected=3) into a new browser. the code keeps assigning the radiobuttonlist1.selectedindex to -1.
so here’s what i’m seeing in debug mode
Case 1 when i cut and past the url in to a new browser http://test.com/test.aspx?selected=1, at the end of the page_load method code RadioButtonList1.SelectedIndex is equal to = -1. for some reason it’s’ not assigning the selectindex correctly.
Case 2 when i select a radio button within the web page i launched, it skips the page_load code because post back is true. then creates a url within the RadioButtonList1_SelectedIndexChanged. then runs through the on page load method and hold the correct RadioButtonList1.SelectedIndex value at the end.
Case 3 when i select a link within the webpage launched that is using pointing to http://test.com/test.aspx?selected=2, postback is false so it loops though the page_load code and successfully hold the correct RadioButtonList1.SelectedIndex value at the end.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
int selected;
if (Request.QueryString["selected"] != null)
{
if (int.TryParse(Request.QueryString["selected"], out selected))
{
RadioButtonList1.SelectedIndex = selected;
RadioButtonList1.DataBind();
}
}
else
{
int firstart = 0;
RadioButtonList1.SelectedIndex = firstart;
}
}
}
protected void SqlDataSource2_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
}
protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
try{
e.Command.Parameters["@URL_FK"].Value = Session["URL_PK"];
}
catch (Exception ex)
{
}
}
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
string strRedirect;
strRedirect = "test.aspx?selected=" + RadioButtonList1.SelectedIndex;
Response.Redirect(strRedirect);
}
}
My session parameter was not taking in the correct value on SqlDataSource1_Selecting. i removed the code which and hardcoded the session parameter in the aspx to get my code working correctly. thanks for everyone’s input! i’m glad this one is over.
