Controls and events on Radgrid pop up edit form

[Sean]

Hi. I have a rad grid with a number of columns, including two date columns. I am using an auto generated pop up form for editing data. On the edit form I would like to make it so that when the user sets a date in the first date field, if the second field is blank the value of the second field is set to one year after the date in the first field. I have tried to add client side and server side code to achieve this but am having no luck getting the right combination of event handlers and control references. Any help would be really appreciated.

Hi Sean,

Please try the following code snippet to set the date field in editform.

ASPX:

<telerik:GridDateTimeColumn DataField="Orderdate" UniqueName="Orderdate" HeaderText="OrderDate">
</telerik:GridDateTimeColumn>
<telerik:GridDateTimeColumn DataField="RequiredDate" UniqueName="RequiredDate" HeaderText="RequiredDate">
</telerik:GridDateTimeColumn>

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
  if (e.Item is GridEditableItem && e.Item.IsInEditMode)
  {
    GridEditableItem editItem = (GridEditableItem)e.Item;
    RadDatePicker orderdate = (RadDatePicker)editItem["Orderdate"].Controls[0];
    orderdate.AutoPostBack = true;
    orderdate.SelectedDateChanged += new Telerik.Web.UI.Calendar.SelectedDateChangedEventHandler(orderdate_SelectedDateChanged);
  }
}

void orderdate_SelectedDateChanged(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)
{
  RadDatePicker orderDate = sender as RadDatePicker;
  GridEditableItem editItem = orderDate.NamingContainer as GridEditableItem;
  RadDatePicker requiredDate = editItem["RequiredDate"].Controls[0] as RadDatePicker;
  if (requiredDate.SelectedDate == null)
  {
    string orderDateValue= orderDate.SelectedDate.ToString();
    DateTime newOrderDate= Convert.ToDateTime(orderDateValue);
    DateTime newDate = newOrderDate.AddYears(1);// add one year
    requiredDate.SelectedDate = newDate;// set to the second RadDatePicker
  }
}

Thanks,
Princy

Thanks Princy - I'm a VB programmer so I had to convert the code but you gave me all the elements I needed to get it working.
