Insert table in a single cell inside repeater

Question

I am trying to build a table structure using asp.net Repeater like this below:

        column 1      |      Column 2

Row1      cell1               cell2
---------------------------------------
       TABLE 1                 TABLE 2
    ----------------------------------
        col1|Col2|Col3_     same  column and rows are here as well   
Row2    row1____|____|____  
        row2___ |____|_____  
        row3____|____|_____

But I got stuck in adding Table 1 and Table 2 for the Row 2. I am not sure how to add the table in a single cell inside the Repeater and the data needs to binding from the DataTable.

And below is my code for Repeater:

<asp:Repeater ID="Repeaterp" runat="server">
    <HeaderTemplate>
        <table>
            <tr><th>usedcount</th><th>notUsedCount</th></tr>
    </HeaderTemplate>
    <ItemTemplate>
        <tr>
            <td><asp:TextBox runat="server" ID="txtAvai" Text='<%#Eval("Count") %>' ReadOnly="true"></asp:TextBox></td>
            <td><asp:TextBox runat="server" ID="txtConv" Text='' ReadOnly="true"></asp:TextBox></td>
        </tr>
    </ItemTemplate>
    <FooterTemplate>
        </table>
    </FooterTemplate>
</asp:Repeater

Could any one please suggest any idea on this one that would be very grateful to me?

You can nest different asp.net Data Representation controls (e.g. asp:Repeater, asp:DataList, asp:GridView or asp:Table etc.) inside a Repeater control. I have added a quick example for making a nested structure with multiple Repeater controls:

.Aspx Code:

<asp:Repeater ID="RepeaterTable" OnItemDataBound="RepeaterTable_ItemDataBound" runat="server">
    <HeaderTemplate>
        <table>
            <tr>
                <th>Column 1</th>
                <th>Column 2</th>
            </tr>
    </HeaderTemplate>
    <ItemTemplate>
        <asp:Panel ID="PanelTextBoxes" runat="server">
            <tr>
                <td>
                    <asp:TextBox ID="txtAvai" Text='<%# Eval("Count") %>' runat="server"></asp:TextBox>
                </td>
                <td>
                    <asp:TextBox ID="txtConv" Text='' runat="server"></asp:TextBox>
                </td>
            </tr>
        </asp:Panel>
        <asp:Panel ID="PanelTables" runat="server">
            <tr>
                <td>
                    <asp:Repeater ID="RepeaterTable1" OnItemDataBound="RepeaterTable1_ItemDataBound" runat="server">
                        <HeaderTemplate>
                            <table>
                                <tr>
                                    <th>T1 Col 1</th>
                                    <th>T1 Col 2</th>
                                </tr>
                        </HeaderTemplate>
                        <ItemTemplate>
                                <tr>
                                    <td>
                                        <asp:Label ID="lblCol1" runat="server" Text='<%# Eval("Col1") %>'></asp:Label>
                                    </td>
                                    <td>
                                        <asp:Label ID="lblCol2" runat="server" Text='<%# Eval("Col2") %>'></asp:Label>
                                    </td>
                                </tr>
                        </ItemTemplate>
                        <FooterTemplate>
                            </table>
                        </FooterTemplate>
                    </asp:Repeater>
                </td>
                <td>
                    <asp:Repeater ID="RepeaterTable2" OnItemDataBound="RepeaterTable2_ItemDataBound" runat="server">
                        <HeaderTemplate>
                            <table>
                                <tr>

                                        <asp:Label ID="lblCol1" runat="server" Text='<%# Eval("Col1") %>'></asp:Label>
                                    </td>
                                    <td>
                                        <asp:Label ID="lblCol2" runat="server" Text='<%# Eval("Col2") %>'></asp:Label>
                                    </td>
                                </tr>
                        </ItemTemplate>

.Aspx.cs Code:

DataTable TempDT = new DataTable();

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        getData();
    }
}

// create DataTable 3 x 2
public void getData()
{
    TempDT = new DataTable();
    TempDT.Columns.Add("Col1");
    TempDT.Columns.Add("Col2");
    TempDT.Columns.Add("Count");
    TempDT.Rows.Add("Temp", "Temp", 100);
    TempDT.Rows.Add("Temp", "Temp", 100);
    TempDT.Rows.Add("Temp", "Temp", 100);

    // store DataTable into ViewState from lost on PostBack
    ViewState["DT"] = TempDT;

    RepeaterTable.DataSource = TempDT;
    RepeaterTable.DataBind();
}

// Calls parent Repeater on Binding Data
protected void RepeaterTable_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    // check Repeater item type is not in edit mode
    if (e.Item.ItemType == ListItemType.Item || 
        e.Item.ItemType == ListItemType.AlternatingItem)
    {
        DataTable dt = new DataTable();

        // get and set DataTable from ViewState
        dt = ViewState["DT"] as DataTable;

        Repeater RepeaterTable1 = e.Item.FindControl("RepeaterTable1") as Repeater;
        Repeater RepeaterTable2 = e.Item.FindControl("RepeaterTable2") as Repeater;

        RepeaterTable1.DataSource = dt;
        RepeaterTable1.DataBind(); // calls RepeaterTable1_ItemDataBound event

        RepeaterTable2.DataSource = dt;
        RepeaterTable2.DataBind(); // // calls RepeaterTable2_ItemDataBound event

        Panel PanelTextBoxes = e.Item.FindControl("PanelTextBoxes") as Panel;
        Panel PanelTables = e.Item.FindControl("PanelTables") as Panel;

        // show only first structure
        if (e.Item.ItemIndex != 0)
        {

    }

// Calls child Repeater on Binding Data
protected void RepeaterTable2_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    // check Repeater item type is not in edit mode
    if (e.Item.ItemType == ListItemType.Item || 
        e.Item.ItemType == ListItemType.AlternatingItem)
    {
        //.. here is code when child repeater is binding
    }
}

Update:

If you don't want to repeat the whole structure then just add below code in RepeaterTable_ItemDataBound event:

Panel PanelTextBoxes = e.Item.FindControl("PanelTextBoxes") as Panel;
Panel PanelTables = e.Item.FindControl("PanelTables") as Panel;

if (e.Item.ItemIndex != 0)
{
    PanelTextBoxes.Visible = false;
    PanelTables.Visible = false;
}

Not repeating the whole structure image demo:
