Declarative Data Source

The RadDataForm can be easily bound to various declarative data source controls. In order to successfully bind the control you need to follow the steps below:

  1. Create and configure a DataSource control. RadDataForm can use any ASP.NET data source control, including SqlDataSource, AccessDataSource, ObjectDataSource, XmlDataSource, EntityDataSource, OpenAccessDataSource, LinqDataSource and ObjectContainerDataSource.

  2. Assign the DataSourceID property of RadDataForm to the previously created DataSource control.

  3. Define the templates for the RadDataForm that will be used to preview, edit, insert or delete data (LayoutTemplate, ItemTemplate, EditItemTemplate, InsertItemTemplate). You can do this manually in the markup or use the Configuration Wizard to generate the layouts manually.

Create and Configure DataSource Control

Before you can bind the RadDataForm, you need to add a DataSource control to the page and configure it. The code below shows a sample markup for a SqlDataSource control.

<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString='<%$ ConnectionStrings:NorthwindConnectionString %>' 
    SelectCommand="SELECT [CustomerID], [CompanyName], [ContactName], [ContactTitle] FROM [Customers]" />

Set the DataSourceID property of RadDataForm

After you set the DataSourceID property to point to the DataSource created in the previous step, the markup will look like below.

<telerik:RadDataForm RenderMode="Lightweight" runat="server" ID="RadDataForm1" DataSourceID="SqlDataSource1" DataKeyNames="CustomerID">
</telerik:RadDataForm>

Define templates for RadDataForm

In order to define how the data will look, you need to configure the templates of the control. You can do this manually or via the Configuration Wizard. The complete markup for RadDataForm with the templates will look similar to the one below.

<telerik:RadDataForm RenderMode="Lightweight" runat="server" ID="RadDataForm2" DataSourceID="SqlDataSource1" DataKeyNames="CustomerID">
    <LayoutTemplate>
        <div class="RadDataForm RadDataForm_<%# Container.Skin %> rdfLeftAligned rdfNoFieldHint rdfNoFieldHint">
