I have added like this...

C#

DataGridViewCheckBoxColumn checkColumn = new DataGridViewCheckBoxColumn();

               checkColumn.AutoSizeMode =
                   DataGridViewAutoSizeColumnMode.DisplayedCells;
               checkColumn.CellTemplate = new DataGridViewCheckBoxCell();
               checkColumn.FalseValue = true;
               checkColumn.HeaderText = "SelectCompany";
               checkColumn.Name = "CheckBoxes";
               checkColumn.TrueValue = true;
               checkColumn.FalseValue = false;
               dgvGetCompanyDetails.Columns.Add(checkColumn);

But I am not able to check the checkboxes

Hi,

you can use TemplateFields for the GridView:

                 <asp:GridView ID="GridView1" runat="server">

                   <Columns>

                        <asp:TemplateField >
                             <ItemTemplate>
                                 <asp:CheckBox ID="myCheckBox" runat="server" />
                             </ItemTemplate>
                         </asp:TemplateField>

                  </Columns>

               </asp:GridView>



Hope this helps:)

That's a GridView not a DataGridView - there is a difference. That and the post is over 3 years old

Solution 1

Once you have your data in the grid, you can loop through the rows and check each box like this:

C#

foreach (DataGridViewRow row in dataGridView1.Rows)
    {
        row.Cells[CheckBoxColumn1.Name].Value = true;
    }

The Click event you can get like this:

C#

private void button1_Click(object sender, EventArgs e)
    {
        List<DataGridViewRow> rows_with_checked_column = new List<DataGridViewRow>();
        foreach (DataGridViewRow row in dataGridView1.Rows)
        {
            if (Convert.ToBoolean(row.Cells[CheckBoxColumn1.Name].Value) == true)
            {
                rows_with_checked_column.Add(row);
            }
        }
        // Do what you want with the check rows
    }
