Find CheckBox Inside a repeater in another button click event

I have two nested repeater and a check box inside that, like this

<asp:Repeater ID="rptInterestCategory" runat="server" OnItemDataBound="rptInterestCategory_ItemDataBound">
        <ItemTemplate>
            <asp:Repeater ID="rptInterests" runat="server" OnItemDataBound="rptInterests_ItemDataBound">
                <ItemTemplate>
                    <asp:CheckBox ID="cbInterest" runat="server" OnCheckedChanged="cbInterest_CheckedChanged" Data-Id='<%# DataBinder.Eval(Container.DataItem, "id") %>' Text='<%# DataBinder.Eval(Container.DataItem, "name") %>' />

                </ItemTemplate>
            </asp:Repeater>
            <hr/>
        </ItemTemplate>
    </asp:Repeater>

Now on another button click event I want to find which all checkboxes(cbInterest )are checked and need to get the value inside it. What will be the correct approach to do this?

The way you would loop through them is to first get a reference to the nested Repeater:

Repeater rptInterests = (Repeater)rptInterestCategory.FindControl("rptInterests");

And then you can loop through the data items, find the checkbox, and get the value of the CheckBox:

foreach (RepeaterItem item in rptInterests.Items)
{
    CheckBox cbInterest = (CheckBox)item.FindControl("cbInterest");
    bool isChecked = cbInterest.Checked;
}
