[Solved] RadDatePicker FormTemplate

[Bernhard Rosenfelder]

hi,

i get an exception when using raddatepicker within grid formtemplate for creating a new item.
the raddatepicker is bound. editing existing itemes works fine.

<telerik:RadDatePicker ID="DatePickerWJBeginnDatum" runat="server"
    DateInput-DateFormat="dd.MM.yyyy"
    SelectedDate='<%# Bind("WjBeginnDatum") %>'
    Width="400px">
</telerik:RadDatePicker>

thank you for your help

Hello Bernhard ,

You can use the DbSelectedDate property instead of SelectedDate .The DbSelectedDate property behaves exactly like the SelectedDate property. The only difference is that it will not throw an exception if the new value is null or DBNull. Setting a null value will internally revert the SelectedDate to the null value, i.e. the input value will be empty.

ASPX:

<telerik:RadDatePicker DbSelectedDate='<%# Bind("WjBeginnDatum") %>' ID="DatePickerWJBeginnDatum"
                       MinDate="1/1/1800" runat="server" DateInput-DateFormat="dd.MM.yyyy" Width="400px">
 </telerik:RadDatePicker>

Another suggessition is to set the SelectedDate from code behind.
Sample code is given below.
C#:

protected void RadGrid1_ItemDataBound1(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditFormItem && e.Item.IsInEditMode && !e.Item.OwnerTableView.IsItemInserted)
    {
        GridEditFormItem editItem = (GridEditFormItem)e.Item;
        GridDataItem item = (GridDataItem)editItem.ParentItem;
        DataRowView rowview = (DataRowView)item.DataItem;
        RadDatePicker datepick = (RadDatePicker)editItem.FindControl("DatePickerWJBeginnDatum");
        datepick.SelectedDate = Convert.ToDateTime(rowview["WjBeginnDatum"].ToString());
    }
}

ASPX:

<telerik:RadDatePicker ID="DatePickerWJBeginnDatum"
                      MinDate="1/1/1800" runat="server" DateInput-DateFormat="dd.MM.yyyy" Width="400px">
 </telerik:RadDatePicker>

Thanks,
Princy.
