Question

Copy Table from one Dataset to Another Dataset

Asked by: zorvek

I have two datasets and I need to move the table in one to the other in order to set up a relation between the two so I can do repeater inside a repeater. This is what I have but it isn't working:

Agreements remittedAgreements = new Agreements();
RemittedContracts remittedContracts = new RemittedContracts();
remittedAgreements.Data.Load(remittedContracts.Data.CreateDataReader()); <--- this part doesn't fail but it does not copy the table
remittedAgreements.Data.DataSet.Relations.Add("Relation",
   remittedAgreements.Data.DataSet.Tables[0].Columns["AgreementID"],
   remittedAgreements.Data.DataSet.Tables[1].Columns["AgreementID"]);
RepeaterRemittedAgreements.DataSource = remittedAgreements.Data;
RepeaterRemittedAgreements.DataBind();

The classes are initialized using the SQLHelper class:

                  DataSet dataSet =
                        SqlHelper.ExecuteDataset(
                              SqlHelper.connection(CurrentSession.ConnectionStringName()),
                              CommandType.StoredProcedure,
                              "GetRemittedContracts"
                        );

Tried this:

remittedAgreements.Data.DataSet.Tables.Add(remittedContracts.Data.DataSet.Tables[0]);

but got an error stating the table already belongs to a dataset.

Got the table copied:

                  remittedAgreements.Data.DataSet.Tables[0].TableName = "RemittedAgreements";
                  remittedContracts.Data.DataSet.Tables[0].TableName = "RemittedContracts";
                  remittedAgreements.Data.DataSet.Tables.Add(remittedContracts.Data.DataSet.Tables[0].Copy());
                  remittedAgreements.Data.DataSet.Relations.Add("Relation",
                        remittedAgreements.Data.DataSet.Tables["RemittedAgreements"].Columns["AgreementID"],
                        remittedAgreements.Data.DataSet.Tables["RemittedContracts"].Columns["AgreementID"]);
                  RepeaterRemittedAgreements.DataSource = remittedAgreements.Data;
                  RepeaterRemittedAgreements.DataBind();

But I can't get the embedded repeater to pull the data:

<asp:Repeater id="RepeaterRemittedAgreements" runat="server">
   <ItemTemplate>
      <b><%# DataBinder.Eval(Container.DataItem, "AgreementID") %><br>
      <asp:Repeater ID="RepeaterRemittedContracts" datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("Relationship") %>' runat="server">
         <ItemTemplate>
            <%# DataBinder.Eval(Container.DataItem, "OptionDescription")%><br>
         </ItemTemplate>
      </asp:Repeater>
   </ItemTemplate>
</asp:Repeater>

Kevin,

Try copying the DataTable....

    remittedAgreements.Data.DataSet.Tables.Add(remittedContracts.Data.DataSet.Tables[0].Copy);

Fixed a spelling error and added the [\" and \"] parts around the embedded repeater field reference. I don't understand it but it works :-)

<asp:Repeater id="RepeaterRemittedAgreements" runat="server">
      <ItemTemplate>
            <b><%# DataBinder.Eval(Container.DataItem, "AgreementID") %><br>
            <asp:Repeater ID="RepeaterRemittedContracts" datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("Relation") %>' runat="server">
                  <ItemTemplate>
                        <%# DataBinder.Eval(Container.DataItem, "[\"OptionDescription\"]")%><br>
                  </ItemTemplate>
            </asp:Repeater>
      </ItemTemplate>
</asp:Repeater>
