更新数据库accdb后绑定源更新报错

Question

I have a winform connected to.accdb file, but while creating rdlc report I found that the naming wa not correct in my accdb file(contained hyphen) and I changed it accordingly and configured the data-set query too and refreshed the connection, but still during execution the below error is coming.

System.ArgumentException: 'Cannot bind to the property or column Condition_of_DIE-7 on the DataSource.

Parameter name: dataMember'

And this is my master table SQL:

SELECT
    ID,
    Size_in_mg,
    Die_head_number,
    Inspection_Date,
    Next_Calibration_On,
    Die_size_in_microns,
    Condition_of_DIE_1,
    Condition_of_DIE_2,
    Condition_of_DIE_3,
    Condition_of_DIE_4,
    Condition_of_DIE_5,
    Condition_of_DIE_6,
    Condition_of_DIE_7,
    Observations,
    Inspector,
    Issued_to_Maintanance
FROM MSdies

And this is where the error is showing is my program.cs file

static void Main()
{
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new FormMsdies());
}

As I am very new to C# I can't understand how to correct this please help me: please refer the below images for further help:

Answer 1

Your columns are defined as Condition_of_DIE_7 and so on, but the error shows clearly that somewhere in your code, you're still using a - instead of a _ :

System.ArgumentException: 'Cannot bind to the property or column Condition_of_DIE-7 on the DataSource.
