如何将值从文本框传递到带有循环的datagridview winform C＃ [英] How to pass values from textbox to datagridview winform C# with loop

问题描述

有4个文本框（txt1，txt2，txt3和txt4）。这4个文本框包含的值如

 txt1 = accNo | txt2 =发布者| txt3 =价格| txt4 = qty 
 500 | Geeta发布者| 350 | 5 

我想将文本框值传递给Datagridview，如下所示。

 AccNo |出版商|价格
 500 | Geeta发布者| 350 
 501 | Geeta发布者| 350 
 502 | Geeta发布者| 350 
 503 | Geeta发布者| 350 

AccNo将被添加到DataGridView中5次（在数量中提到）并自动增加1.



请帮忙......



我尝试过的事情：

解决方案

尝试

 private void button1_Click（object sender，EventArgs e）
 {
 int accountNo; 
双倍价格; 
 int数量; 
 string publisher = txtPublisher.Text.Trim（）; 
 if（！int.TryParse（txtAccNo.Text.Trim（），out accountNo））
 {
 MessageBox.Show（请输入有效的账号）; 
返回; 
} 
 if（！int.TryParse（txtqty.Text.Trim（），out quantity））
 {
 MessageBox.Show（请输入有效数量）; 
返回; 
} 
 if（！double.TryParse（txtPrice.Text.Trim（），out price））
 {
 MessageBox.Show（请输入有效价格）; 
返回; 
} 
 
 DataTable dt = new DataTable（）; 
 dt.Columns.Add（AccNo，typeof（int））; 
 dt.Columns.Add（Publisher）; 
 dt.Columns.Add（Price，typeof（double））; 
 for（int i = 0; i< quantity; i ++）
 {
 DataRow row = dt.NewRow（）; 
 row [AccNo] = accountNo + i; 
 row [发布商] =发布商; 
行[价格] =价格; 
 dt.Rows.Add（row）; 
 
} 
 dataGridView1.DataSource = dt; 
} 

请使用适当的控件命名约定，这将有助于您轻松找到代码中的控件

There are 4 textboxes (txt1, txt2, txt3 & txt4). These 4 textboxes contains values like

txt1=accNo | txt2=Publisher   |  txt3=Price | txt4=qty
500        | Geeta Publisher  |  350        | 5

I want to pass my textbox values into Datagridview as bellow shown.

AccNo | Publisher          | Price 
500   | Geeta Publisher    | 350 
501   | Geeta Publisher    | 350
502   | Geeta Publisher    | 350 
503   | Geeta Publisher    | 350

AccNo will be added into DataGridView 5 times (mentioned in qty) and auto increase by 1.

Please help....

try

private void button1_Click(object sender, EventArgs e)
        {
            int accountNo;            
            double price;
            int quantity;
            string publisher = txtPublisher.Text.Trim();
            if(!int.TryParse(txtAccNo.Text.Trim(),out accountNo))
            {
                MessageBox.Show("Please enter valid Account Number");
                return;
            }
            if (!int.TryParse(txtqty.Text.Trim(), out quantity))
            {
                MessageBox.Show("Please enter valid quantity");
                return;
            }
            if (!double.TryParse(txtPrice.Text.Trim(), out price))
            {
                MessageBox.Show("Please enter valid price");
                return;
            }

            DataTable dt = new DataTable();
            dt.Columns.Add("AccNo", typeof(int));
            dt.Columns.Add("Publisher");
            dt.Columns.Add("Price", typeof(double));
            for (int i = 0; i < quantity; i++)
            {
                DataRow row = dt.NewRow();
                row["AccNo"] =   accountNo + i;
                row["Publisher"] = publisher;
                row["Price"] = price;
                dt.Rows.Add(row);

            }
            dataGridView1.DataSource = dt;
        }

Please use a proper naming convention to the controls which will help you to find the controls in the code behind easily.
