Data Binding

Binding a RadDatePicker control to a data source is easy provided you use the DbSelectedDate property. It works almost like the SelectedDate one, but does not throw an exception when given a null value.

When embedding a RadDatePicker control inside a data-bound control, use a data-binding expression to bind the value of the input control to the data source of the parent control. Data-binding expressions are contained within <%# and %> delimiters and use the Eval and Bind functions. The Eval function is used to define one-way (read-only) binding. The Bind function is used for two-way (updatable) binding.

note

In addition to calling Eval and Bind methods to perform data binding in a data-binding expression, you can call any publicly scoped code within the <%# and %> delimiters to execute that code and return a value during page processing.

Data-binding the picker control

The following example demonstrates how to bind a RadDatePicker control inside a RadGrid, as shown above.

<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server" AutoGenerateColumns="False" Width="300px"
    OnNeedDataSource="RadGrid1_NeedDataSource" OnUpdateCommand="RadGrid1_UpdateCommand"
    OnItemCreated="RadGrid1_ItemCreated">
    <MasterTableView Width="100%" EditMode="InPlace">
        <Columns>
            <telerik:GridTemplateColumn HeaderText="Available dates" UniqueName="TemplateColumn">
                <ItemTemplate>
                    <asp:Label runat="server" ID="date" Text='<%# Eval("Dates", "{0:D}") %>'>
                    </asp:Label>
                    &nbsp;
                </ItemTemplate>
                <EditItemTemplate>
                    <telerik:RadDatePicker RenderMode="Lightweight" ID="picker1" MinDate="2006/1/1" runat="server" DbSelectedDate='<%# Bind("Dates") %>'>
                    </telerik:RadDatePicker>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridEditCommandColumn ButtonType="ImageButton" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
