[Solved] RadDateInput inside EditItemTemplate

[Chris]

Hi and thanks for your help in advance.

I've currently got a RadGrid bound to an EntityDataSource and I'm trying to do the following it works fine for edits but the moment I try and do an insert I get the following message 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'StartDate'.

<EditItemTemplate>
    <telerik:RadDatePicker ID="StartDate" runat="server" SelectedDate='<%# Bind("StartDate") %>' />
    <asp:RequiredFieldValidator ID="DataRequired" runat="server" ControlToValidate="StartDate"
        ErrorMessage="Required" />
</EditItemTemplate>

I've noticed most of the examples seem to avoid using a RadDatePicker inside a grid and I'm starting to think I've discovered why...

Hello Chris,

The reason for this error is that your grid instance can not bind a value for the newly inserted item through the Eval()/Bind() syntax you hard-coded(This you can find mentioned in this help document as well)
To resolve this issue, you would have to preset the default value of the RadDatePicker when binding to a grid item on the
InitInsert Command as shown below:

c#:

protected void RadGrid1_ItemCommand(object  source, Telerik.Web.UI.GridCommandEventArgs e)
{
            if (e.CommandName == RadGrid.InitInsertCommandName)
            {
               e.Canceled = true;
               //Prepare an IDictionary with the predefined values
               System.Collections.Specialized.ListDictionary newValues = new  System.Collections.Specialized.ListDictionary();
               newValues["StartDate"] = "value";
               //Insert the item and rebind
               e.Item.OwnerTableView.InsertItem(newValues);
           }
}

Thanks
