单击该行的复选框后，如何在datagridview中启用文本框？ [英] How do I enable textbox in datagridview after clicking checkbox of that row ?

问题描述

点击复选框，它必须启用同一行，datagridview的文本框的下一列。但这里启用下一行textbox.how我是否限制它只启用相同的行textbox.using c＃code



我尝试过：

公共部分类Form1 ：Form 
 {
 public Form1（）
 {
 InitializeComponent（）; 
 dataGridView1.Columns [AMOUNT]。Visible = false; 
 
 // LoadSerial（）; 
 
} 
 / * private void dataGridView1_CellEndEdit（object sender，DataGridViewCellEventArgs e）
 {
 LoadSerial（）; 
} * / 
 
 // int COUNTER = 0; 
 private void button1_Click（object sender，EventArgs e）
 {
 
 
 // ADDDATA（textBox2.Text，textBox1.Text）; 
 //字符串EMINITIESNAME = textBox2.Text; 
 // string DESCRIPTION = textBox1.Text; 
 int row = 0; 
 dataGridView1.Rows.Add（）; 
 row = dataGridView1.Rows.Count  -  2; 
 dataGridView1 [AMENITIESNAME，row] .Value = textBox2.Text; 
 dataGridView1 [DESCRIPTION，row] .Value = textBox1.Text; 
 LoadSerial（）; 
 
} 
 private void LoadSerial（）
 {
 int i = 1; 
 foreach（DataGridViewRow dataGridView1.Rows中的行）
 {
 row.Cells [ID]。Value = i;我++; 
} 
 
} 
 
 
 public void ADDDATA（string AMENITIESNAME，string DESCRIPTION）
 {
 int row = 0; 
 dataGridView1.Rows.Add（）; 
 row = dataGridView1.Rows.Count  -  2; 
 dataGridView1 [AMENITIESNAME，row] .Value = textBox2.Text; 
 dataGridView1 [DESCRIPTION，row] .Value = textBox1.Text; 
 
 
} 
 
 
 
 
 private void Form1_Load（object sender，EventArgs e）
 {
 
} 
 
 private void textBox1_TextChanged（object sender，EventArgs e）
 {
 
} 
 
 
 
私人空隙dataGridView1_CellContentClick（对象发件人，DataGridViewCellEventArgs E）
 {
 
 
的foreach（的DataGridViewRow dataGridRow在dataGridView1.Rows）
 {
如果（dataGridRow.Cells [ SELECT]值= NULL&安培;！及（布尔）dataGridRow.Cells [ SELECT]值。）
 {
 
 dataGridView1.Columns [ AMOUNT]。可见=真; 
 
 
} 
 
 else if（dataGridRow.Cells [SELECT]。Value == null）
 {
 // Unchecked 
} 
 
} 
} 
 

解决方案

首先来自DataGridView属性，将AllowUserToAddRows从True更改为False



更改的片段：



更改row = dataGridView1.Rows.Count -2; torow = dataGridView1.Rows.Count -1;在您的方法。

私人无效dataGridView1_CellContentClick（对象发件人，DataGridViewCellEventArgs E）
 {
如果（e.RowIndex > -1）
 {
 var curCell = dataGridView1.CurrentCell; 
 if（curCell.Value == null ||（bool）curCell.Value == false）
 {
 curCell.Value = true; 
} 
其他
 {
 curCell.Value = false; 
} 
 
 if（（bool）curCell.Value）
 {
 
 dataGridView1.Columns [AMOUNT]。Visible = true; 
} 
 else 
 {
 dataGridView1.Columns [AMOUNT]。Visible = false; 
} 
} 
} 

如果有效，请将此标记为解决方案。

clicking on checkbox it has to enable the same row ,next column of textbox of datagridview .but here its enabling the next row textbox.how do i restrict it to enable only the same row textbox.using c# code

What I have tried:

public partial class Form1 : Form
   {
       public Form1()
       {
           InitializeComponent();
           dataGridView1.Columns["AMOUNT"].Visible = false;

           //  LoadSerial();

       }
       /*   private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
          {
              LoadSerial();
          }*/

       // int COUNTER = 0;
       private void button1_Click(object sender, EventArgs e)
       {


           //ADDDATA(textBox2.Text, textBox1.Text);
           //string EMINITIESNAME = textBox2.Text;
           //string DESCRIPTION = textBox1.Text;
           int row = 0;
           dataGridView1.Rows.Add();
           row = dataGridView1.Rows.Count - 2;
           dataGridView1["AMENITIESNAME", row].Value = textBox2.Text;
           dataGridView1["DESCRIPTION", row].Value = textBox1.Text;
           LoadSerial();

       }
       private void LoadSerial()
       {
           int i = 1;
           foreach (DataGridViewRow row in dataGridView1.Rows)
           {
               row.Cells["ID"].Value = i; i++;
           }

       }


       public void ADDDATA(string AMENITIESNAME, string DESCRIPTION)
       {
           int row = 0;
           dataGridView1.Rows.Add();
           row = dataGridView1.Rows.Count - 2;
           dataGridView1["AMENITIESNAME", row].Value = textBox2.Text;
           dataGridView1["DESCRIPTION", row].Value = textBox1.Text;


       }




       private void Form1_Load(object sender, EventArgs e)
       {

       }

       private void textBox1_TextChanged(object sender, EventArgs e)
       {

       }



       private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
       {


           foreach (DataGridViewRow dataGridRow in dataGridView1.Rows)
           {
               if (dataGridRow.Cells["SELECT"].Value != null && (bool)dataGridRow.Cells["SELECT"].Value)
               {

                   dataGridView1.Columns["AMOUNT"].Visible = true;


               }

               else if (dataGridRow.Cells["SELECT"].Value == null)
               {
                   // Unchecked
               }

           }
       }

解决方案

First from the DataGridView property, change "AllowUserToAddRows" from "True" to "False"

Changed Snippets:

Change "row = dataGridView1.Rows.Count -2;" to "row = dataGridView1.Rows.Count -1;" in your methods.

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex > -1)
            {
                var curCell = dataGridView1.CurrentCell;
                if (curCell.Value == null || (bool)curCell.Value == false)
                {
                    curCell.Value = true;
                }
                else
                {
                    curCell.Value = false;
                }

                if ((bool)curCell.Value)
                {

                    dataGridView1.Columns["AMOUNT"].Visible = true;
                }
                else
                {
                    dataGridView1.Columns["AMOUNT"].Visible = false;
                }
            }
        }
