Question

I have setup up a gridview to contain a column of checkboxes like this:

                    <asp:TemplateField HeaderText = "Editor">
                        <ItemTemplate>
                             <asp:CheckBox ID="chkRemove" runat="server" AutoPostBack="false" Checked='<%#currentMember(Eval("GroupID")) %>' />
                        </ItemTemplate>
                    </asp:TemplateField>

The function, currentMember, returns true or false.

The user will be able to uncheck rows to remove the member status.

Now, once the user hits submit, how do I determine which rows the user has unchecked so I can update the database?

Answer 1

Put the following code in your submit button click handler

for (int i = 0; i < gridView.Rows.Count; i++)
{
    CheckBox cbox = (CheckBox)gridView.Rows[i].FindControl("chkRemove");
    if(cbox.Checked){
        //DO DATABASE STUFF
    }
}
