dont use quotes in first parameter:
cmd = new SqlCommand("Select * from UserProfile Where "+_var_search+"='" + _var_by + "'", con);
even better use paramaters:
cmd = new SqlCommand("Select * from UserProfile Where "+_var_search+"=#param", con);
cmd.Parameters.AddWithValue("#param", _var_by);

I want to ask, why do you want to do a search, but when you type it in the search text box, the data in the grid view disappears (it doesn't appear).
I think you are missing databind in the gridview

I'm developing a winform application using C#.net, using DataGridView to display the data, but after the last update, the DataGridView returns 1 last row, but i want my DataGridView to return a blank row or just show the header only...
nb: Before the update JmlKirimK value is 1.
try
{
con.Close();
con.Open();
MySqlCommand cmd = new MySqlCommand("Select PasienID, NoHP, JmlKirimK from datapasien where JmlKirimK ='1' AND StatusDiabetes='Ya'", con);
DataTable dt = new DataTable();
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
da.Fill(dt);
foreach (DataRow dr in dt.Rows)
{
con.Close();
con.Open();
nohp = Convert.ToString(dr[1]);
idpasien = Convert.ToString(dr[0]);
jml = Convert.ToString(dr[2]);
Cursor.Current = Cursors.WaitCursor;
if (objclsSMS.sendMsg(this.port2, nohp, this.txtisi.Text))
{
MySqlCommand cmd3 = new MySqlCommand("UPDATE datapasien SET JmlKirimK='2' Where PasienID='" + idpasien.Trim() + "'", con);
cmd3.ExecuteNonQuery();
terkirim = terkirim + 1;
showgridkirimulang();
}
else
{
tdkterkiri = tdkterkiri + 1;
}
showgridkirimreset();
}
con.Close();
alert.ContentImage = SmsGatewayProlanis.Properties.Resources.Warning1;
alert.CaptionText = "Status";
alert.ContentText = "Pesan Terkirim = " + terkirim + ", Pesan Tidak Terkirim = " + tdkterkiri;
alert.Show();
}
catch (Exception ex)
{
alert.ContentImage = SmsGatewayProlanis.Properties.Resources.Warning1;
alert.CaptionText = "Status";
alert.ContentText = ex.Message;
alert.Show();
ErrorLog(ex.Message);
}
This is my DataGridView code

I'm trying to show when an inventory is lower than critical. It doesn't seem to get there when I debug the system
This is my code behind

cmd.Connection = con;
cmd.CommandText = "SELECT 'Total Count of Inventory ' + '(' + convert(nvarchar,SUM(Quantity)) + ')' AS TotalCount from Inventory";
SqlDataReader data = cmd.ExecuteReader();
if (data.HasRows)
{
while (data.Read())
{
lblTotalCount.Text = data["TotalCount"].ToString();
}
con.Close();
}
else
{
con.Close();
Response.Redirect("Default.aspx");
}
}
void GetInventory()
{
con.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandText = "SELECT Inventory.InventoryID, Products.ProductName, " +
"Supplier.SupplierName, Inventory.Quantity, Users.LastName + ', ' + Users.FirstName AS UserAccount, " +
"SupplierProducts.CriticalLevel, Inventory.Status, Inventory.DateAdded, Inventory.DateModified, SupplierProducts.Price FROM Inventory " +
"INNER JOIN SupplierProducts ON Inventory.ProductID = SupplierProducts.SupplierProductID " +
"INNER JOIN Products ON SupplierProducts.ProductID = Products.ProductID " +
"INNER JOIN Supplier ON Inventory.SupplierID = Supplier.SupplierID " +
"INNER JOIN Users ON Inventory.UserID = Users.UserID";
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds, "Inventory");
lvInventory.DataSource = ds;
lvInventory.DataBind();
con.Close();
}
void CriticalItem()
{
var intcheck = new DataTable();
using (var da = new SqlDataAdapter("SELECT * FROM Inventory", con))
{
da.Fill(intcheck);
}
var critcheck = new DataTable();
using (var da = new SqlDataAdapter("SELECT * FROM SupplierProducts", con))
{
da.Fill(critcheck);
}
int finalQuantity = Convert.ToInt32(intcheck.Rows[0]["Quantity"]);
int criticalLevel = Convert.ToInt32(critcheck.Rows[0]["CriticalLevel"]);
if (finalQuantity > criticalLevel)
{
Panel1.Visible = true;
criticalItem.Text = "Available";
}
}
I want to criticalItem.text to tell the Inventory that is less than its critical level.

one way to access to table is index of columns or if you want to find with columns name you can write name "" in []
