DataGridView在另一个窗体上插入细节后没有更新[C＃]

这是数据网格视图窗体，其中第二个窗体将在显示时出现添加成员按钮被单击。DataGridView在另一个窗体上插入细节后没有更新[C＃]

private void btnAddMember_Click(object sender, EventArgs e) 
    { 
     Cashier_NewMember F_Cashier_NewMember = new Cashier_NewMember(); 

     F_Cashier_NewMember.Show(); 
    }

这是我将插入成员详细信息的表单。

private void btnAddMember_Click(object sender, EventArgs e) 
    { 
     try 
     { 
      if (sqlCon.State == ConnectionState.Closed) 
       sqlCon.Open(); 

      if (btnAddMember.Text == "Add Member") 
      { 

       if (string.IsNullOrWhiteSpace(txtFirstName.Text) || string.IsNullOrWhiteSpace(txtLastName.Text) || string.IsNullOrWhiteSpace(txtMobileNo.Text) || string.IsNullOrWhiteSpace(txtHomeNo.Text) || string.IsNullOrWhiteSpace(txtAddress.Text) || string.IsNullOrWhiteSpace(txtPostcode.Text) || string.IsNullOrWhiteSpace(txtCity.Text) || string.IsNullOrWhiteSpace(txtCountry.Text)) 
        MessageBox.Show("All fields are required!", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning); 

       else if (string.IsNullOrWhiteSpace(txtMemberID.Text)) 
        MessageBox.Show("Please generate a Member ID!", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning); 

       else 
       { 
        SqlCommand sqlCmd = new SqlCommand("AddOrUpdateMembership", sqlCon); 
        sqlCmd.CommandType = CommandType.StoredProcedure; 
        sqlCmd.Parameters.AddWithValue("@mode", "Add"); 
        sqlCmd.Parameters.AddWithValue("@Member_ID", txtMemberID.Text); 
        sqlCmd.Parameters.AddWithValue("@Member_Since_Date", dtpMemberSince.Value.Date); 
        sqlCmd.Parameters.AddWithValue("@Title", cmbTitle.GetItemText(cmbTitle.SelectedItem)); 
        sqlCmd.Parameters.AddWithValue("@First_Name", txtFirstName.Text.Trim()); 
        sqlCmd.Parameters.AddWithValue("@Last_Name", txtLastName.Text.Trim()); 
        sqlCmd.Parameters.AddWithValue("@DOB", dtpDOB.Value.Date); 
        sqlCmd.Parameters.AddWithValue("@Gender", cmbGender.GetItemText(cmbGender.SelectedItem)); 
        sqlCmd.Parameters.AddWithValue("@Mobile_No", cmbMobileNo.GetItemText(cmbMobileNo.SelectedItem) + txtMobileNo.Text.Trim()); 
        sqlCmd.Parameters.AddWithValue("@Home_No", cmbHomeNo.GetItemText(cmbHomeNo.SelectedItem) + txtHomeNo.Text.Trim()); 
        sqlCmd.Parameters.AddWithValue("@House_Address", txtAddress.Text.Trim()); 
        sqlCmd.Parameters.AddWithValue("@Post_Code", txtPostcode.Text.Trim()); 
        sqlCmd.Parameters.AddWithValue("@City", txtCity.Text.Trim()); 
        sqlCmd.Parameters.AddWithValue("@City_State", txtState.Text.Trim()); 
        sqlCmd.Parameters.AddWithValue("@Country", txtCountry.Text.Trim()); 

        sqlCmd.ExecuteNonQuery(); 
    }

这是我用于填充数据网格视图

public void FillDataGridView() 
    { 
     Cashier_NewMember F_Cashier_NewMember = new Cashier_NewMember(); 

     if (sqlCon.State == ConnectionState.Closed) 
      sqlCon.Open(); 

     SqlDataAdapter sqlDa = new SqlDataAdapter("ViewOrSearchMembership", sqlCon); 
     sqlDa.SelectCommand.CommandType = CommandType.StoredProcedure; 
     sqlDa.SelectCommand.Parameters.AddWithValue("@Member_ID", F_Cashier_NewMember.txtMemberID.Text); 
     DataTable dtbl = new DataTable(); 
     sqlDa.Fill(dtbl); 
     dgvMembershipDetails.DataSource = dtbl; 

     sqlCon.Close(); 
    }

这是我用来搜索和填充数据网格视图中存储的过程的代码。

CREATE PROCEDURE [dbo].[ViewOrSearchMembership] 
    @Member_ID VARCHAR(10) 
AS 
    SELECT * 
    FROM Member 
    WHERE Member_ID LIKE @Member_ID + '%'

我试着加入FillDataGridView（）无处不在，但在数据网格视图仍然没有更新。

如何/你在哪里补充DataTable之后你添加或更新。由于您手动操作，因此它不会自动出现在DGV中，尤其是因为您并未坚持使用表 – Plutonix

：确保数据已插入到“成员”中表格检查momber表格告诉我数据是否已插入 –

@Plutonix恩，我点击添加按钮后尝试在两个表单上重新填充 –

试试这个分配后的数据源，dgvMembershipDetails.update（）

dgvMembershipDetails.Databind（）你应该在分配数据源行后放置。

'DataGridView'没有这样的方法 – Plutonix

确保您dgvMembershipDetails修饰符是公共然后尝试明确的DataGridView之前填补它

public void FillDataGridView(){ 
    Cashier_NewMember F_Cashier_NewMember = new Cashier_NewMember(); 

    if (sqlCon.State == ConnectionState.Closed) 
     sqlCon.Open(); 

    SqlDataAdapter sqlDa = new SqlDataAdapter("ViewOrSearchMembership", sqlCon); 
    sqlDa.SelectCommand.CommandType = CommandType.StoredProcedure; 
    sqlDa.SelectCommand.Parameters.AddWithValue("@Member_ID", F_Cashier_NewMember.txtMemberID.Text); 
    DataTable dtbl = new DataTable(); 
    sqlDa.Fill(dtbl); 
    dgvMembershipDetails.DataSource =null; 
    dgvMembershipDetails.DataSource = dtbl; 

    sqlCon.Close(); 
}
