Error Message

Hi Naimish

  It is giving error message : Label does not contain a definition for InnerHtml

lblErrorMessage.InnerHtml = System.Web.HttpUtility.HtmlEncode(errMessage);

Thanks

Hello Ramco,

IS there any reason why are you using 
? could you please try only

if (String.IsNullOrWhiteSpace(txtBankName.Text))
{
    errMessage += "Bank Name is required and cannot Be empty.
";
}

Boolean IsValidDescription = Common.CommonFunction.IsAlpha(txtBankName.Text);
if (IsValidDescription == false)
{
    errMessage += "Bank Name : Only Alphabets , Space , _ - allowed.
";
}

To ensure that the
tags are interpreted as line breaks in the error message rather than being displayed as text, you can use the InnerHtml property of the label instead of the Text property. This way, the HTML tags will be rendered correctly.

Here’s how you can modify your code:

1. Update the Label Control to Use InnerHtml

Ensure your label control is set to use InnerHtml:

2. Set the Error Message Using InnerHtml

In your code-behind, set the InnerHtml property of the label:

protected void btnSubmit_Click(object sender, EventArgs e)
{
    string errMessage = "";

    if (String.IsNullOrWhiteSpace(txtBankName.Text))
    {
        errMessage += "Bank Name is required and cannot be empty.
";
    }

    Boolean IsValidDescription = Common.CommonFunction.IsAlpha(txtBankName.Text);
    if (IsValidDescription == false)
    {
        errMessage += "Bank Name: Only Alphabets, Space, _ - allowed.
";
    }

    if (errMessage == "")
    {
        try
        {
            if (hdfId.Value == "0")
            {
                using (SqlConnection con = new SqlConnection(Common.CommonFunction.cnn_Live))
                {
                    SqlCommand cmd = new SqlCommand("Sp_Bank", con);
                    cmd.CommandType = CommandType.StoredProcedure;

                    cmd.Parameters.AddWithValue("@Action", "I");
                    cmd.Parameters.AddWithValue("@BankCode", SqlDbType.VarChar).Value = txtBankCode.Text.ToUpper();
                    cmd.Parameters.AddWithValue("@BankName", SqlDbType.VarChar).Value = txtBankName.Text.ToUpper();
                    SqlParameter successParam = cmd.Parameters.Add("@Success", SqlDbType.Bit);
                    successParam.Direction = ParameterDirection.Output;
                    con.Open();

                    cmd.ExecuteNonQuery();
                    bool success = (bool)successParam.Value;
                    if (success)
                    {
                        string message = Common.CommonFunction.recordInsertedSucessfully;
                        ShowMessage("Success", message, "Success");
                    }
                    else
                    {
                        ShowMessage("Oops...", success.ToString(), "error");
                    }
                }
            }

        }
        catch (Exception ex)
        {
            ShowMessage("Oops...", Common.CommonFunction.ErrorMessage, "error");
        }
    }
    else
    {
        if (errMessage == "")
        {
            ShowMessage("Oops...", Common.CommonFunction.ErrorMessage, "error");
        }
        else
        {
            hfErrorMessage.Value = System.Web.HttpUtility.HtmlEncode(errMessage);
            lblErrorMessage.Text = hfErrorMessage.Value; // This line should be changed
            lblErrorMessage.InnerHtml = errMessage; // Add this line
            ScriptManager.RegisterStartupScript(this, this.GetType(), "ShowModal", "$('#modal_form_horizontal').modal('show');", true);
        }
    }
}

Explanation

• lblErrorMessage.Text = hfErrorMessage.Value;: This line sets the text of the label, which will display the HTML tags as plain text.
• lblErrorMessage.InnerHtml = errMessage;: This line sets the inner HTML of the label, which will render the HTML tags correctly as line breaks.

By using InnerHtml, the
tags will be rendered as line breaks in the error message, ensuring the message is displayed correctly within the modal.

Thanks
