C# .NET - Data Grid view with CHECKBOX column

Hi, can some on help me with my problem?

How can I add a checkbox column programmatically and making it as a first column.

here is my code, but the checkbox is at the last column.

private void Form1_Load(object sender, EventArgs e)
      {
        string stat = "";
        int ave = 0;
        dataGridView1.ColumnCount = 5;


        DataGridViewCheckBoxColumn chk = new DataGridViewCheckBoxColumn();
        dataGridView1.Columns.Add(chk);
        chk.HeaderText = "Check Data";
        chk.Name = "chk";

        dataGridView1.Columns[1].Name = "Substation/Office";
        dataGridView1.Columns[2].Name = "IP Address";
        dataGridView1.Columns[3].Name = "Status";
        dataGridView1.Columns[4].Name = "Average";

        string[] row = new string[] { "ce", "1", stat};
        dataGridView1.Rows.Add(row);
        row = new string[] { " Da", "1.1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "s", "19", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "cat", "1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "te", "6.1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "ffice", ".1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "ca", "51.1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "ban", "1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "Office", "1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "or", "19", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "Sur", "19", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "C", "3.1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "Norte", "1", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "Sto", "10", stat };
        dataGridView1.Rows.Add(row);
        row = new string[] { "mail", "1", stat };
        dataGridView1.Rows.Add(row);
      }



the checkbox column always appear at the last column of the grid view.

Thank You :)

See the following article, it will help you to generate the checkbox column dynamically in Gridview

hi,

here is the code for you


or


hope this will help you

do something like below

dataGridView1.Columns[0].Name = "chk"; // or your headertext

add your column at 0 th position..

that's all..

its simple instead of Columns.Add() use Insert like;

DataGridViewCheckBoxColumn chk = new DataGridViewCheckBoxColumn();
//dataGridView1.Columns.Add(chk);

dataGridView1.Columns.Insert(0, chk); //Specify index of column as 0 so that it will insert this column as first column...

Hi Mai,

Good Day

The columns appear in the order that their column styles were added to the tablestyle being used by the grid. If you want to change this order, you would need to create a new table style, and add the columnstyles in the order you want things to appear. Here is some code snippets that suggest how to do this in C#.

public void MoveColumn(DataGrid _dataGrid, string _mappingName, int fromCol, int toCol)
 
{
 
   if(fromCol == toCol) return;
 

 
   DataGridTableStyle oldTS = _dataGrid.TableStyles[_mappingName];
 
   DataGridTableStyle newTS = new DataGridTableStyle();
 
   newTS.MappingName = _mappingName;
 

 
   for(int i = 0; i < oldTS.GridColumnStyles.Count; ++i)
 
   {
 
      if(i != fromCol && fromCol < toCol)
 
         newTS.GridColumnStyles.Add(oldTS.GridColumnStyles[i]);
 
      if(i == toCol)
 
         newTS.GridColumnStyles.Add(oldTS.GridColumnStyles[fromCol]);
 
      if(i != fromCol && fromCol > toCol)
 
         newTS.GridColumnStyles.Add(oldTS.GridColumnStyles[i]);   
 
   }
 

 
   _dataGrid.TableStyles.Remove(oldTS);
 
   _dataGrid.TableStyles.Add(newTS);
 
}
 

 
//sample usage
 
private void button1_Click(object sender, System.EventArgs e)
 
{
 
   MoveColumn(myDataGrid, "Customers", 3, 1);
 
}
 
Hope this helps :)

If you have addded all other column as design time why dont you add your check box column also at a design time...

That will solve all problem i guess.... and which is simple and better way as well.... other wise add other columns also dynamically in your code....

check this link to add check box column in datagridview as design time;
