The database for this page is

Project_Group_Type (Master Table)
columns (Basic ones):  

Project_Group_Type_ID Description
1 New

Project_Group (Details Table)
columns(Basic ones) :   
Column Name Value
Project_Group_ID 1
Project_Group_Type_ID 1
Project_Group_Description Check


The DataSource

The data source for the Master Datagrid consists of these columns: Project_Group_Type_ID, Description

The data source for the Details Datagrid consists of these columns: Project_Group_ID Project_Group_Type_ID Project_Group_Description

The Datagrid is within another Datagrid (Figure 1).The master Datagrid has project categories Type  and details Datagrid have projects Categories. The detail table has a foreign to the master table.

 



Figure 1

The details Datagrid is expanded as shown in Figure 2.

Figure 2

Now the user can add/edit/delete row to the master/details Datagrid. Now I have created this as user control and used in other aspx pages.

The code is as follows. Declare the Datagrid with following attributes.

<asp:DataGrid ID="dgProjectGroupType" ShowFooter="True" ShowHeader="false" AutoGenerateColumns="False"

CellSpacing="0" BorderStyle="None" BorderWidth="0" GridLines="None" CellPadding="0" Width="100%" runat="server"            OnItemDataBound="dgProjectGroupType_ItemDataBound" OnItemCommand="dgProjectGroupType_ItemCommand">

I have enabled show footer = true in order to add new record for this grid. I have added a new row with textbox and add button. And since I donot require the header have set it to false. I have following events for

  • ItemDataBound: To bind the Inner grid with outer grid.
  • ItemCommand: Handling the events on the master like add,edit,cancel...etc

<FooterStyle Font-Size="Smaller"  />

<ItemStyle Font-Size="Smaller" />

<EditItemStyle BackColor="#CADDEE" Font-Size="Smaller" />

<SelectedItemStyle BackColor="#D1DDF1" Font-Bold="True"       ForeColor="#333333" Font-Size="Smaller" />

<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" Font-Size="Smaller" />

<HeaderStyle Font-Size="Smaller" />

<AlternatingItemStyle Font-Size="Smaller" />

This is style format I have used for grid, which self explanatory.

<Columns>

The "Columns" is declared under "<Columns>" tags since AutoGenerateColumns is "False".

 

<asp:TemplateColumn HeaderText="" >

<FooterTemplate>

           <asp:TextBox ID="addDescription" runat="Server" />

      </FooterTemplate>

      <ItemTemplate>

&nbsp;&nbsp;&nbsp; <b> <%#DataBinder.Eval(Container.DataItem,"Description")%>

</b>

      </ItemTemplate>

      <EditItemTemplate>

          <asp:TextBox ID="storDescription"

Text=

'<%# DataBinder.Eval(Container.DataItem,"Description")%>'

            runat="server" />

       </EditItemTemplate>

</asp:TemplateColumn>

The footer template, editItem template, item template  for this column are declared under "asp:TemplateColumn".

<asp:TemplateColumn HeaderText="">

<ItemTemplate>

<asp:Label ID="projectGroupTypeID" runat="server" Text=

'<%# DataBinder.Eval(Container.DataItem, "Project_Group_Type_Id")%>' Visible="False" />

      </ItemTemplate>

</asp:TemplateColumn>

This column is used for the editing the master records. This column is the primary key for this master table. Hence made invisible and retrived by the ID of lable and used in internal operations.

<asp:TemplateColumn HeaderText="">

<ItemTemplate>

<asp:DataGrid ID="dgProjectGroup" ShowFooter="True" ShowHeader="true" AutoGenerateColumns="False"

BorderWidth="0" GridLines="None" CellPadding="0" Width="100%" runat="server" OnItemCommand="dgProjectGroup_ItemCommand"

            OnItemDataBound="dgProjectGroup_OnItemDataBound">

 

                   <FooterStyle Font-Size="Smaller" />

            <ItemStyle Font-Size="Smaller" />

            <EditItemStyle BackColor="#CADDEE" Font-Size="Smaller" />

<SelectedItemStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" Font-Size="Smaller" />

<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" Font-Size="Smaller" />

<HeaderStyle Font-Size="Smaller" />

<AlternatingItemStyle Font-Size="Smaller" />

Here in the "asp:TemplateColumn" where columns are decalred, another datagrid is declared. I have following events for

  • ItemDataBound : refer See code in css.
  • ItemCommand  : Handling the events on the details grid like add, edit, cancel...etc

This is style format I have used for grid, which self explainatary.

<Columns>

The "Columns" is declared under "<Columns>" tags since AutoGenerateColumns is "False".

                   <asp:TemplateColumn HeaderText="">

                             <ItemTemplate>

<asp:Label ID="projectGroupDescription" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Project_Group_Description")%>'

                  Width="275px" />

                    </ItemTemplate>

            <EditItemTemplate>

<asp:TextBox ID="txtGroup" Text='<%# DataBinder.Eval(Container.DataItem, "Project_Group_Description") %>'

                  runat="server" Width="275px" />

                </EditItemTemplate>

      <FooterTemplate>

<asp:TextBox ID="addProject" runat="Server" Text="" />

<asp:TextBox ID="addProjectTypeID" runat="Server" Text="" Visible="False" />

            </FooterTemplate>

</asp:TemplateColumn>

Then in the detials datagrid ,Iam displaying the project group description in an itemTemplate,displaying in textbox in edit mode and displaying a empty text on footer of the datagrid.

<asp:TemplateColumn>

          <ItemTemplate>

<asp:Button ID="cmdEditprojectGroup" runat="server" Text="Edit" CommandName="EditGroup" />

<asp:Button ID="cmdDeleteprojectGroup" runat="server" Text="Delete" CommandName="DeleteGroup" />

            </ItemTemplate>

            <EditItemTemplate>

<asp:Button ID="cmdUpdateMeasure" runat="server" Text="Save" CommandName="SaveGroup" />

<asp:Button ID="cmdCancelEditprojectGroup" runat="server" Text="Cancel" CommandName="CancelGroup" />

            </EditItemTemplate>

<FooterStyle    VerticalAlign="Middle"></FooterStyle>

            <FooterTemplate>

<asp:Button ID="cmdAddMeasure" CommandName="InsertGroup" runat="server" Text="Add" />

            </FooterTemplate>

</asp:TemplateColumn>

Again in the details datagrid ,Iam displaying the Edit & delete buttons in an itemTemplate,displaying in save & cancel buttons in edit mode and displaying a add button on footer of the datagrid.

<asp:TemplateColumn HeaderText="" Visible="False">

                   <ItemTemplate>

<asp:Label ID="projectGroupTypeID" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Project_Group_Type_ID")%>' Visible="False" />

            </ItemTemplate>

</asp:TemplateColumn>

 

<asp:TemplateColumn HeaderText="" Visible="False">

                   <ItemTemplate>

<asp:Label ID="projectGroupID" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Project_Group_ID")%>' Visible="False" />

            </ItemTemplate>

</asp:TemplateColumn>

 

In the details Datagrid, projectGroupTypeID and projectGroupID are used displayed on the itemtemplate but not visible to users. As these are used for edit and deleting operations.

 

</Columns>

</asp:DataGrid>

End of Inner DataGrid

</ItemTemplate>

End of ItemTemplare of Master DataGrid.

Start of EditItemTemplare for Master DataGrid.

And this is EditItemTemplate for this column when editing. So by another grid in the edititemtemplate you can see still see inner datagrid while editing master Datagrid.

<EditItemTemplate>

<asp:DataGrid ID="dgProjectGroup_Edit" AutoGenerateColumns="False" CellSpacing="0"

SkinID="datagridSkinID" CssClass="dataTable" BorderStyle="None" BorderWidth="0"

GridLines="None" CellPadding="0" Width="100%" runat="server" OnItemCommand="dgProjectGroup_ItemCommand"

            OnItemDataBound="dgProjectGroup_OnItemDataBound">

            <Columns>

`                  <asp:TemplateColumn HeaderText="">

<FooterStyle Font-Size="Small" Font-Bold="false" Wrap="false" BackColor="White" />

                             <ItemTemplate>

<asp:Label ID="projectGroupDescription" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Project_Group_Description")%>'

                              Width="275px" />

                        </ItemTemplate>

 

                        <FooterTemplate>

<asp:TextBox ID="addProject" runat="Server" Text="" />

<asp:TextBox ID="addProjectTypeID" runat="Server" Text="" Visible="False" />

                        </FooterTemplate>

                  </asp:TemplateColumn>

            </Columns>

          </asp:DataGrid>

       </EditItemTemplate>

//end of EditItemTemplate

    </asp:TemplateColumn>

//end of TemplateColumn

    <asp:TemplateColumn>

          <ItemTemplate>

<asp:Button ID="cmdEditMeasure" runat="server" Text="Edit Category" CommandName="EditCategory" />

<asp:Button ID="cmdDeleteProjectGroupType" runat="server" Text="Delete Category" CommandName="DeleteCategory"

OnClientClick="return confirm('Are you sure you wish to Delete all?');" />

      </ItemTemplate>

      <EditItemTemplate>

<asp:Button ID="btnUpdateMeasure" runat="server" Text="Save Category" CommandName="SaveCategory" />

<asp:Button ID="cmdCancelEditProjectGroupType" runat="server" Text="Cancel Category" CommandName="CancelCategory" />

</EditItemTemplate>

<FooterStyle VerticalAlign="Middle"></FooterStyle>

<FooterTemplate>

<asp:Button ID="cmdAddCategory" CommandName="InsertCategory" runat="server" Text="Add Category" />

</FooterTemplate>

</asp:TemplateColumn>

Again in the Master datagrid, Iam displaying the Edit & delete buttons in an itemTemplate,displaying in save & cancel buttons in edit mode and displaying a add button on footer of the datagrid.

</Columns>

</asp:DataGrid>

End of master Datagrid.
