RadioButtonList: OnSelectedIndexChanged not firing

Question

I have an aspx page where i dynamically add a radiobuttonlist with OnSelectedIndexChanged event. In the event i check for the selected items. i have 2 items.

For the first item,the event is firing well, However if i choose the other option the event is not firing: below the code..

The event is only firing is i change from "Some provided" to "All provided" the other way it is not working

Adding the RBL:

                RadioButtonList dControl_b = new RadioButtonList();
                dControl_b.ID = "rbl_MinCriteria";
                dControl_b.RepeatDirection = System.Web.UI.WebControls.RepeatDirection.Horizontal;
                dControl_b.CssClass = "Font";
                dControl_b.Font.Name = "Arial";
                dControl_b.Font.Size = 8;
                dControl_b.ToolTip = "";
                dControl_b.SelectedIndex = -1;
                dControl_b.SelectedIndexChanged += new EventHandler(rbl_MinCriteria_SelectedIndexChanged);
                dControl_b.AutoPostBack = true;

Checking the selected item:

   if(rbl_MinCriteria.SelectedItem.ToString() == "All provided")
   {
       cbl_MinimumCriteria.Items[0].Selected = true;
       cbl_MinimumCriteria.Items[1].Selected = true;
       cbl_MinimumCriteria.Items[2].Selected = true;
       cbl_MinimumCriteria.Items[3].Selected = true;
       cbl_MinimumCriteria.Enabled = false;

       //*************************************************************
       if (ddl_CountryOccurence.SelectedValue != "Please choose")
       {
           ddl_CountryOccurence.Enabled = false;
       }
       else
       {
           ddl_CountryOccurence.Enabled = true;
       }

       //*************************************************************
       if (tb_DueDate.Text != "")
       {
           tb_DueDate.Enabled = false;
       }
       else
       {
           tb_DueDate.Enabled = true;
       }

       OtherControlI.Enabled = false;
       OtherControlII.Enabled = false;
       OtherControlIII.Enabled = false;
   }
   if (rbl_MinCriteria.SelectedItem.ToString() == "Some provided")
   {
       cbl_MinimumCriteria.Items[0].Selected = false;
       cbl_MinimumCriteria.Items[1].Selected = false;
       cbl_MinimumCriteria.Items[2].Selected = false;
       cbl_MinimumCriteria.Items[3].Selected = false;
       cbl_MinimumCriteria.Enabled = true;

       //*************************************************************
       if (ddl_CountryOccurence.SelectedValue != "Please choose")
       {
           ddl_CountryOccurence.Enabled = false;
       }
       else
       {
           ddl_CountryOccurence.Enabled = true;
       }

       //*************************************************************
       if (tb_DueDate.Text != "")
       {
           tb_DueDate.Enabled = false;
       }
       else
       {
           tb_DueDate.Enabled = true;
       }

       OtherControlI.Enabled = false;
       OtherControlI.SelectedIndex = -1;
       OtherControlII.Enabled = false;
       OtherControlII.SelectedIndex = -1;
       OtherControlIII.Enabled = false;
       OtherControlIII.SelectedIndex = -1;
   }

Any help and Comment is much appreciated

Answer 1

This is for people who find this question from Google:

On the RadioButtonList, set the AutoPostBack property to true.

RadioButtonList OnSelectedIndexChanged

Answer 2

I have this problem and solved it.

For raising onselectedindexchanged event of RadioButtonList , check below items:

       <asp:RadioButtonList ID="rdlCondition" runat="server" AutoPostBack="True" 
        onselectedindexchanged="rdlCondition_SelectedIndexChanged">

and in the Page_Load set them with code :

     rdlCondition.AutoPostBack = true;
     rdlCondition.SelectedIndexChanged += new EventHandler (rdlCondition_SelectedIndexChanged);

Looking at the code above there seems to be alot of code reuse. I reorganized your code a bit (assuming you didnt leave anything out). Keep in mind I never tested it.

protected void rbl_MinCriteria_SelectedIndexChanged(object sender,EventArgs e)
{
   if (rbl_MinCriteria.SelectedIndex<0) return; //If nothing is selected then do nothing

       OtherControlI.Enabled = false;
       OtherControlII.Enabled = false;
       OtherControlIII.Enabled = false;
   if(rbl_MinCriteria.SelectedItem.ToString() == "All provided")
   {
       cbl_MinimumCriteria.Items[0].Selected = true;
       cbl_MinimumCriteria.Items[1].Selected = true;
       cbl_MinimumCriteria.Items[2].Selected = true;
       cbl_MinimumCriteria.Items[3].Selected = true;
       cbl_MinimumCriteria.Enabled = false;

   }
   if (rbl_MinCriteria.SelectedItem.ToString() == "Some provided")
   {
       cbl_MinimumCriteria.Items[0].Selected = false;
       cbl_MinimumCriteria.Items[1].Selected = false;
       cbl_MinimumCriteria.Items[2].Selected = false;
       cbl_MinimumCriteria.Items[3].Selected = false;
       cbl_MinimumCriteria.Enabled = true;

       OtherControlI.SelectedIndex = -1;
       OtherControlII.SelectedIndex = -1;
       OtherControlIII.SelectedIndex = -1;
   }

   //*************************************************************
   if (ddl_CountryOccurence.SelectedValue != "Please choose")
   {
       ddl_CountryOccurence.Enabled = false;
   }
   else
   {
       ddl_CountryOccurence.Enabled = true;
   }
   //*************************************************************
   if (tb_DueDate.Text != "")
   {
     tb_DueDate.Enabled = false;
   }
   else
   {
       tb_DueDate.Enabled = true;
   }
}

I know this doesn't help your current problem but this is just a suggestion. If you could post the code where your actually adding the values to the list I could help a bit more.

EDIT: Your problem could be your not setting the value of your items, only the text. Try using rbl_MinCriteria.SelectedItem.Text =="All provided" instead.

Answer 4

I've made a sample aspx page, and added one panel in .aspx like below:

<asp:Panel ID="Panel1" runat="server"></asp:Panel>

And in code behind, I've added following code:

protected void Page_Load(object sender, EventArgs e)
    {
        RadioButtonList dControl_b = new RadioButtonList();
        dControl_b.ID = "rbl_MinCriteria";
        dControl_b.RepeatDirection = System.Web.UI.WebControls.RepeatDirection.Horizontal;
        dControl_b.CssClass = "Font";
        dControl_b.Font.Name = "Arial";
        dControl_b.Font.Size = 8;
        dControl_b.ToolTip = "";
        dControl_b.SelectedIndex = -1;
        dControl_b.SelectedIndexChanged += new          EventHandler(rbl_MinCriteria_SelectedIndexChanged);
        dControl_b.AutoPostBack = true;

        dControl_b.Items.Add(new ListItem("All provided"));
        dControl_b.Items.Add(new ListItem("Some provided"));

        Panel1.Controls.Add(dControl_b);
    }
    protected void rbl_MinCriteria_SelectedIndexChanged(object sender,EventArgs e)
    {
        RadioButtonList rbl_MinCriteria = (RadioButtonList)Panel1.FindControl("rbl_MinCriteria");
       if(rbl_MinCriteria.SelectedItem.ToString() == "All provided")
       {

       }
       if (rbl_MinCriteria.SelectedItem.ToString() == "Some provided")
       {

       }

    }

The event is FIRING EVERY TIME the radio button listitem is changed.

So, I'm afraid, you have done something wrong elsewhere. Good luck.
