CheckBoxList_SelectedIndexChanged Problem

Posted on 2013-06-20

Hello Experts,

I have the following HTML and CodeBehind below that works ok. But the little problem that I'm facing is that if someone clicks on the actual CheckBox square then it runs the CheckBoxList_SelectedIndexChanged fine.

But if someone just clicks on the name/label of the CheckBox square value then the CheckBoxList_SelectedIndexChanged does not run.

Any idea how I can make the CheckBoxList_SelectedIndexChanged Event fire if the actual name/label is selected?

HTML:
<asp:Label ID="lblCurrentlyReceive" runat="server" CssClass="formlabel" Text="Do you currently receive:"></asp:Label>
                <asp:CheckBoxList ID="cblCurrentlyReceiveValues" OnSelectedIndexChanged="cblCurrentlyReceiveValues_SelectedIndexChanged" runat="server" AutoPostBack="true"></asp:CheckBoxList>
                <asp:Label ID="lblCurrentlyReceiveExplain" runat="server" Text="Explain"></asp:Label>
                <asp:TextBox ID="txtCurrentlyReceiveOtherInfo" runat="server"></asp:TextBox>

Open in new window


CodeBehind:
protected void Page_Load(object sender, EventArgs e)
    {
        txtCurrentlyReceiveOtherInfo.Visible = false;
        lblCurrentlyReceiveExplain.Visible = false;

        RetrieveCurrentlyReceieveData();
        }
    }  

protected void RetrieveCurrentlyReceieveData()
    {
        DataTable dtCurrentlyReceiveValues = new DataTable();

        SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["TMF"].ConnectionString);

        SqlCommand cmd = new SqlCommand();
        cmd.CommandText = "RetrieveCurrentlyReceiveData";
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Connection = conn;

        SqlDataAdapter adp = new SqlDataAdapter();
        adp.SelectCommand = cmd;
        adp.Fill(dtCurrentlyReceiveValues);

        try
        {
            conn.Open();

            cblCurrentlyReceiveValues.DataSource = dtCurrentlyReceiveValues;
            cblCurrentlyReceiveValues.DataValueField = "cr_id";
            cblCurrentlyReceiveValues.DataTextField = "cr_name";
            cblCurrentlyReceiveValues.DataBind();
        }

        catch (Exception ex)
        {
            ex.Message.ToString();
        }

        finally
        {
            conn.Close();
        }
    }

    protected void cblCurrentlyReceiveValues_SelectedIndexChanged(object sender, EventArgs e)
    {
        var strtext = cblCurrentlyReceiveValues.SelectedIndex.ToString();

        if (cblCurrentlyReceiveValues.SelectedIndex != -1)
        {
            strtext = cblCurrentlyReceiveValues.SelectedItem.Text;
        }

        if (strtext == "Other Government Assistance")
        {
            if (cblCurrentlyReceiveValues.SelectedItem.Selected)
            {
                txtCurrentlyReceiveOtherInfo.Visible = true;
                lblCurrentlyReceiveExplain.Visible = true;
            }
            else
            {
                txtCurrentlyReceiveOtherInfo.Visible = false;
                lblCurrentlyReceiveExplain.Visible = false;
            }
        }
        else
        {
            txtCurrentlyReceiveOtherInfo.Visible = false;
            lblCurrentlyReceiveExplain.Visible = false;
        }
    }

No, even if it did I can't have it solely rely on just certain browsers.

When you debug the program which one is the value of the strtext on this line when you click on the text portion of the checkbox??

var strtext = cblCurrentlyReceiveValues.SelectedIndex.ToString();

@k-designers,

Hi, I set a breakpoint on the line that you suggested on your last post but when I ran my application that breakpoint was never hit, in other words there wasn't a value for strtext.

Below is the code that I'm using as mentioned in original post.

    protected void cblCurrentlyReceiveValues_SelectedIndexChanged(object sender, EventArgs e)
    {
        var strtext = cblCurrentlyReceiveValues.SelectedIndex.ToString();

        if (cblCurrentlyReceiveValues.SelectedIndex != -1)
        {
            strtext = cblCurrentlyReceiveValues.SelectedItem.Text;
        }

        if (strtext == "Other Government Assistance")
        {
            if (cblCurrentlyReceiveValues.SelectedItem.Selected)
            {
                txtCurrentlyReceiveOtherInfo.Visible = true;
                lblCurrentlyReceiveExplain.Visible = true;
            }
            else
            {
                txtCurrentlyReceiveOtherInfo.Visible = false;
                lblCurrentlyReceiveExplain.Visible = false;
            }
        }
        else
        {
            txtCurrentlyReceiveOtherInfo.Visible = false;
            lblCurrentlyReceiveExplain.Visible = false;
        }
    }

That's the problem. Is not recognizing the event. Delete the sub and from the design side double click on the drop down to generate the select index event again and copy your code again. Add the breakpoint and check If pass throught the whole sub
