<asp:TemplateColumn HeaderStyle-Width="60px" HeaderStyle-CssClass="gridheader">
                                <ItemStyle HorizontalAlign="Center" />
                                <HeaderTemplate>
                                    Is Omani
                                </HeaderTemplate>

                                <ItemTemplate>

                                    <asp:CheckBox ID="chkIsOmani" CssClass="CheckBox" runat="server" Checked='<%#Bind("IsOmani") %>'

                                        OnCheckedChanged="chkIsOmani_CheckedChanged" AutoPostBack="true"   />

                                </ItemTemplate>
                            </asp:TemplateColumn>
                            <asp:TemplateColumn HeaderStyle-Width="60px" HeaderStyle-CssClass="gridheader">
                                <ItemStyle HorizontalAlign="Center" />

                                <ItemTemplate>
                                    <asp:CheckBox ID="chkIsSME" CssClass="CheckBox" runat="server" Checked='<%#Bind("IsSME") %>' ToolTip="IS SME can be selected only if IS Omani is selected"  />
                                </ItemTemplate>

public string CheckOmaniData()
    {
        string _Items = "";
        foreach (DataGridItem _item in dgServices.Items)
        {
            CheckBox chkIsOmani = (CheckBox)_item.FindControl("chkIsOmani");
            CheckBox chkIsSME = (CheckBox)_item.FindControl("chkIsSME");



            if (chkIsOmani.Checked)
            {

                _Items = _Items + _item.Cells[0].Text + ",";


                chkIsSME.Enabled = true;
                chkIsSME.Attributes.Add("onclick", "return true;"); // To retain the value like enabling
            }
            else
            {
                _Items = _Items + _item.Cells[0].Text + ",";

                //chkIsSME.Enabled = false;
                chkIsSME.Attributes.Add("onclick", "return false;"); //To retain original value like disabling
                chkIsSME.Checked = false;

            }


        }
        return _Items.Substring(0, _Items.Length - 1);
    }

    protected void chkIsOmani_CheckedChanged(object sender, EventArgs e)
    {

        CheckOmaniData();
    }

推荐答案

void ProductsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
 {
   // CommandName property to determine which button was clicked.
   if(e.CommandName=="check1")
   {
     // code on checkbox select
   }
}
