Specified cast is not valid. error on RadTimePicker value bind to a grid cell

[Jose]

 <ItemTemplate>
<telerik:RadTimePicker ClientEvents-OnDateSelected="OnDateSelected"  ID="txt_InD1" runat="server" Width="86"  SelectedDate='<%# Eval("InDay1") %>'    ></telerik:RadTimePicker>
</ItemTemplate>

When I run the project, I get an error on the line above saying "Specific cast is not valid" .  Some values coming from the db are empty strings and I am guessing thats causing this issue.  How can I fix empty strings and null values.  my db field is a char(5) and I am only storing the time values such as 3:31, or 4:30 or 12:58 etc.

Hello Robert,

Try using the property DbSelectedDate instead of SelectedDate and see whether it helps you.

<ItemTemplate>

<telerik:RadTimePicker DbSelectedDate='<%# Eval("InDay1") %>'      ClientEvents-OnDateSelected="OnDateSelected"  ID="txt_InD1" runat="server" Width="86"></telerik:RadTimePicker>

</ItemTemplate>

Regards,
Shinu.
