GridView Calendar Column

[Fransiscus Setiawan]

Hi,

I have a question related with the GridView Calendar column. How to make sure that we can put an empty string into a data bound column that uses calendar automatically as its input? The problem is when I set it to an empty string, the calendar control automatically throw me the validation error "Input string is not in correct format". Is there any way we can set the calendar column to accept empty string from the front end without doing its built-in validation?

Cheers

Fransiscus

Hello Fransiscus Setiawan,

You can set your property bound to your column to be of type Nullable. For example, if your column is:

<telerik:RadGridView.Columns>
    <telerik:GridViewDataColumn DataMemberBinding="{Binding Birthday}" />
</telerik:RadGridView.Columns>

Then the property Birthday should be defined as follows:

private DateTime? birthday;

public DateTime? Birthday
{
    get { return this.birthday; }
    set
    {
        if (value != this.birthday)
        {
            this.birthday = value;
            this.OnPropertyChanged("Birthday");
        }
    }
}
