Does anyone know how to access the value of a Boolean which is displayed within a gridview as a checkbox?? The standard Grid view will render a bit type (i.e. Boolean) datatype into an ASP:CheckBoxField, but how can i access the value of the underlying data, either true/false.

Hi,
I have done the similar thing in windows app Gridview's click event,i want to access grid's selected row's 9th cell value which is a check box,try this and make your logic :)

C#

string valuechk = dataGridView1.CurrentRow.Cells[9].Value.ToString ();
// int value = int.Parse(valuechk);
 bool chkvalue = Convert.ToBoolean(valuechk);

 //if (dataGridView1.CurrentRow.Cells[8].Value == "0")
 if(chkvalue ==false)
      assignchk.Checked = false;//assignchk is a check box on form
  else
      assignchk.Checked = true;

Hi,

Try this if could fit to your needs, and could help...

In your client code:

<asp:TemplateField HeaderText="Delete">
                        <ItemTemplate>
                            <asp:CheckBox ID="CheckBox1" runat="server" />
                        </ItemTemplate>
                    </asp:TemplateField>

In your Code behind (example):

protected void btnDelete_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < grdDeleteTransaction.Rows.Count; i++)
        {
            var row = grdDeleteTransaction.Rows[i];
            var isTag = row.FindControl("CheckBox1");
            CheckBox checkbox = (CheckBox)isTag;
            if (checkbox.Checked)
            {
                // Do something here...               
            }
            else
            {
               // Do something here...  
            }
        }
        //.. 
    }
