Hi,

You need to bind the DbSelectedDate property of the date picker instance to avoid the exception so that when the control doesn't have a value it would be left blank in the insert form.

ASPX:

    
            <telerik:RadDatePicker ID="RadDatePicker1" Runat="server" Culture="English (United States)"  
        
            DbSelectedDate='<%# Bind("DateReported") %>' Skin="" >  
        
            <dateinput skin=""></dateinput>  
        
            </telerik:RadDatePicker>

Thanks,
Shinu

Hi Shinu, thanks for the reply.

Unfortunately I receive this error now:

DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'EffectiveDate'.

In case you need it, here is my Grid declaration:

    
            <telerik:RadGrid ID="RadGrid1" runat="server" AllowAutomaticDeletes="True" 
        
                AllowAutomaticInserts="True" AllowAutomaticUpdates="True" AllowPaging="True" AutoGenerateColumns="false" 
        
                DataSourceID="orgProjectDataSource" OnRowDrop="RadGrid1_RowDrop" OnItemInserted="RadGrid1_ItemInserted" 
        
                AllowSorting="true" AllowMultiRowSelection="false">  
        
                <MasterTableView EditMode="PopUp" CommandItemDisplay="Top" DataKeyNames="CoreAbilityID">  
        
                    <Columns>

Hi Princy,

This solution seems hackish to me. Why is it that if I just use textBoxes and bind, it works just fine?

For example, using the following declaration in InsertMode works just fine:

    
                    <EditFormSettings PopUpSettings-Modal="true" FormTableStyle-Width="225" PopUpSettings-Height="265" FormTableStyle-CellPadding="1" EditFormType="Template">  
        
                        <FormTemplate> 
        
                            <br /> 
        
                            <div class="dialog">  
        
                                <label for="txtDescription">Description</label><br /> 
        
                                <asp:TextBox ID="txtDescription" Text='<%# Bind("Description") %>' runat="server" Width="150px"></asp:TextBox> 
        
             ....

In the above scenario, there is no need to handle the ItemCommand event and populate a temporary dictionary object with garbage values to "fake it out". But once you introduce the RadDatePicker to the FormTemplate, then all bets are off. You are left to resort to a hackish solution.

Seems like a bug to me?
