如何在网格中保存数据 [英] How to save data in a Grid

问题描述

private void addbutton_Click(object sender, EventArgs e)
        {
            int StuID = Convert.ToInt32(this.SIDtextBox.Text);
            DataTable dt = cslStudent.GetStudents(StuID);
            this.SelectedStudentGridView.DataSource = dt;
            BindingSource bs = new BindingSource();
            bs.DataSource = dt;
            
            
            int iRowCnt = this.SelectedContainersdataGridView.Rows.Count;
           
            string StudName = this. SelectedStudentGridView.Rows[iRowCnt].Cells[0].Value.ToString();  
            string Address = this. SelectedStudentGridView.Rows[iRowCnt].Cells[1].Value.ToString();    
            string Phone = this. SelectedStudentGridView.Rows[iRowCnt].Cells[2].Value.ToString();     
            

            PHTS.DataServices.cslStudent.NewStudent(StuID, StudName, Address, Phone);

            MessageBox.Show("Student Added Sucessfully");  
            
        }

我在将数据保存到数据库时遇到麻烦.我收到索引超出范围.必须为非负数并且小于集合的大小."

谢谢

I am having trouble in saving data to the database. I am getting "Index was out of range. Must be non-negative and less than the size of the collection."

Thanks

推荐答案

在访问Cells的Row之前，需要先创建它.当然，这是使用自己的变量名的一种方法

Before you can access a Row of Cells, you need to create it. Here''s one way to do it, using your own variable names, of course

int n = grid.Rows.Add();
DataGridViewRow r = grid.Rows[n];
r.Cells[0].Value = ... ;
