RadGrid GridDateTimeColumn DefaultInsertValue Error

[Chuck]

I am trying to set a default insert value.  I have read the forums on how to do this from code-behind, and I have that working.  However I am very curious if there is a way to do this using the documented DefaultInsertValue property.  Whenever I try it, a javascript error is generated:

<

 

telerik:GridDateTimeColumn DataField="InspectionDate" DataType="System.DateTime" DefaultInsertValue='<% = Now().ToString() %>'

FilterControlAltText="Filter colInspectionDate column" HeaderText="Date"

UniqueName="colInspectionDate">

</telerik:GridDateTimeColumn>

I have also tried '<% = Now() %>'.

I get the following error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: The default insert value for column colInspectionDate cannot be converted to type System.DateTime

I am using Q2 2011.  Is this a bug?  Is DefaultInsertValue supposed to work?  Is there a formating option I have to use on the date?  I have been unable to find anyone who has a working example other than the code-behind solution.

Thanks.

Hello Chuck,

Thank you for contacting us and for your question.

First of all, the syntax of your binding expression is incorrect, it should be:

DefaultInsertValue='<%#  Now().ToString() %>'

However, that won't do as well since the GridDateTimeColumn does not support binding expressions. You need to use the code-behind approach.

Hope it helps.

Tsvetoslav,

Thank you for the response.  Just for my own education, for the GridDateTimeColumn does the DefaultInsertValue property do anything?  Or it it just there to spread confusion?  (Not trying to be snarky - I love your products - just curious.)

Hello Chuck,

It certainly does - try setting a valid date for it, e.g.: DefaultInsertValue="09/6/2011". What it allows is a hard-coded date, not a binding expression.
