Hello Developers,

Good Day.
Here i have a issue when i use AutoPostBack="true" on select of radio button, they are getting double, if i select the radio button again they are increasing.

<asp:RadioButtonList ID="rblist" runat="server" OnSelectedIndexChanged="GetAnswerData1" AutoPostBack="true" />


my CS page code is

protected void GetAnswerData1(object sender, EventArgs e)
    {
        if (rblist.SelectedItem.Selected)
        {
            DataTable dTable = InterviewBAL.Load(prms);
            DataRow row = dTable.Rows[0];
            Label1.Text = row["CorrectObjectiveAnswer"].ToString();
            Label2.Text = row["ObjectiveJustify"].ToString();
        }
    }

How to solve this problem, please help me.

Thanks&Regards
iluvdotnetfunda

i m just asking, are you using javascript function/jquery to get answer? and autopostback="true". if so, then set it false.

Thanks,
Rajni Shekhar

There is nothing to do with autopostback because you are setting the autopostback to true only since you have written the server side coding.The problem might be since you are getting it value from the database.Can you put ur full coding page including the page load function that could be better to reseolve

Thanks and Regards

Hi Balajirnaukri, 


protected void Page_Load(object sender, EventArgs e)

    {

        // _userName = User.Identity.Name;



        BindQuestion();

        if (!IsPostBack)

        {            

            dropCategory1.SelectedValue = "0"; // select all the values

            PopulateDefaultValue(Int32.Parse(Resources.SiteConfiguration.Interview));

        }

    }


This is my pageload code.

Thanks.

Hi , 

private void PopulateDefaultValue(int parentCatID)

    {

        CategoryBAL categoryBAL = new CategoryBAL();

        try

        {

            dropCategory1.DataSource = categoryBAL.LoadAll(parentCatID, true);

            dropCategory1.DataBind();

            dropCategory1.Items.Insert(0, new ListItem("Please select"));

        }

        catch (Exception ee)

        {

            lblError.Text = ThrowError.LogAndThrowError(ee.ToString());

        }

        finally

        {

            categoryBAL = null;

        }

    }


Thanks
