Question

I am trying to loop through all the checkboxes and get their Value and if they are checked or not and save the checked/unchecked into database based on the Value which is going to contains the ID of the record. I am trying to do this through asp.net any suggestions?

Here is the code:

            <Columns>
                <asp:TemplateField HeaderText="Application" ItemStyle-Width="25%">
                    <ItemTemplate>                        
                        <%#Eval("App")%>
                    </ItemTemplate>                    
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Edit" ItemStyle-Width="25%">
                    <ItemTemplate>
                        <input name="chkEdit" runat="server" value='<%# Eval("AppID") %>' class="checkbox" type="checkbox" checked='<%# Eval("Edit") %>' />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Delete" ItemStyle-Width="25%">
                    <ItemTemplate>                        
                        <input name="chkDelete" runat="server" value='<%# Eval("AppID") %>' class="checkbox" type="checkbox" checked='<%# Eval("Delete") %>' />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="View" ItemStyle-Width="25%">
                    <ItemTemplate>                        
                        <input name="chkView" runat="server" value='<%# Eval("AppID") %>' class="checkbox" type="checkbox" checked='<%# Eval("View") %>' />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>

string[] controls = new string[] {"chkEdit","chkDelete","chkView"};

foreach (GridViewRow r in YourGridView.Rows)
{
   foreach(string cnt in controls){
     int value =  Convert.ToInt32(((System.Web.UI.HtmlControls.HtmlInputCheckBox)r.FindControl(cnt)).Value);
     bool isChecked = ((System.Web.UI.HtmlControls.HtmlInputCheckBox)r.FindControl(cnt)).Checked;
     //now you have id and checked/unchecked. use your query to save it to database
   }
}
