How to bind a label inside a gridview to another table?
- by Kolten
I have a very standard Gridview, with Edit and Delete buttons auto-generated.
It is bound to a tableadapter which is linked to my "RelationshipTypes" table.
dbo.RelationshipTypes:
ID, Name, OriginConfigTypeID, DestinationConfigTypeID
I wish to use a label that will pull the name from the ConfigTypes table, using the "OriginConfigTypeID" and "DestinationTypeID" as the link.
dbo.ConfigTypes:
ID, Name
My problem is, I can't automatically generate Edit and Delete buttons using an Inner Join in my dataset. Or can I?
FOllowing is my code:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" CssClass="TableList"
DataKeyNames="ID" DataSourceID="dsRelationShipTypes1">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True"
SortExpression="ID" Visible=False/>
<asp:TemplateField HeaderText="Origin" SortExpression="OriginCIType_ID">
<EditItemTemplate>
<asp:DropDownList Enabled=true ID="DropDownList2" runat="server" DataSourceID="dsCIType1"
DataTextField="Name" DataValueField="ID" SelectedValue='<%# Bind("OriginCIType_ID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("OriginCIType_ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Name" SortExpression="Name">
<EditItemTemplate>
<asp:TextBox ID="TextBox3" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label3" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Destination" SortExpression="DestinationCIType_ID">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList3" runat="server" DataSourceID="dsCIType1" DataTextField="Name"
DataValueField="ID" SelectedValue='<%# Bind("DestinationCIType_ID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("DestinationCIType_ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
So I did try to create my own edit and delete buttons, but kept receiving the error "cannot find update method" or something similar. Do I have to manually code the delete and update methods in my code-behind?
