System.Data.EvaluateException: 'Cannot find column [NameID].' - visual-studio

Question

I wanted to use a search textbox to filter a datagridview in Visual Studio, where you will enter a certain primary key (i.e. NameID) to filter the results in the datagridview. It throws the error which is noted in the title.
I have tried changing the code from NameID to [NameID] but this action did not work.
private void TxtNamecSearch_TextChanged(object sender, EventArgs e)
{
DataView dtvNames = new DataView(dtNames);
dtvNames.RowFilter = string.Format("Convert
(NameID,'System.String') Like '%{0}%'", TxtNameSearch.Text); //
Errror occurs on this line
NameDataGridView.DataSource = dtvNames;
}
I expect to type in the textbox, the primary key [NameID] which is a numeric number and the results in the datagridview will automatically filter by the column "NameID"

Answer 1

I have not added the DataColumn named NameID to my DataTable, as this column name "NameID" is being retrieved from MySQL database and it is populated into the Datagridview.
As a result, I had to change the code and this code, below, now works fine: -
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Globalization;
using System.IO;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
using System.Threading.Tasks;
public class Form1
{
private BindingSource NameBindingSource;
private void Form1_Load(System.Object sender, System.EventArgs e)
{
// Create a new DataTable
DataTable dtName = new DataTable();
// Add the NameID column
dtName.Columns.Add(new DataColumn("NameID"));
// Create a new BindingSource
NameBindingSource = new BindingSource();
// Bind the DataTable to the BindingSource
NameBindingSource.DataSource = dtName;
// Bind the BindingSource to the DataGridView
NameDataGridView.DataSource = NameBindingSource;
}
private void TxtNameSearch_TextChanged(System.Object sender, System.EventArgs e)
{
// Set the filter
NameBindingSource.Filter = string.Format("Convert
(NameID, 'System.String') LIKE '%{0}%'", TxtNameSearch.Text);
}
}
