set default DateTime in RadDateTimePicker

[Hadoop]

Language : : C#, ASP.NET​

How can I set default DateTime value in RadDateTimePicker. Default value should be one day greater than the current date with time as "12:00 AM". How can I do this?

Hi,

In order to implement the behavior you can handle the Load event of the RadDateTimePicker and set the appropriate date.

<telerik:RadDateTimePicker runat="server" ID="RadDateTimePicer1" OnLoad="RadDateTimePicer1_Load"></telerik:RadDateTimePicker>

protected void RadDateTimePicer1_Load(object sender, EventArgs e)
{
    (sender as RadDateTimePicker).SelectedDate = DateTime.Today.AddDays(1);
}

How about if the RadDateTimePicker is inserted in a <GridDateTimeColumn> e.g.

<telerik:GridDateTimeColumn DataField="StartDate" PickerType="DateTimePicker" SortExpression="StartDate" UniqueName="StartDate" />

 

How can we set a default datetime for the picker then? I just want to default the picker to NOW()

Hello Adam,

If you mean the inserting form, then you can directly use the following property to achieve that:

<telerik:GridDateTimeColumn ... DefaultInsertValue="5/5/2015">

Alternatively, you can access the generated controls manually:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-editinsert-mode

Analogously, for filtering you can also use ItemDataBound event handler:

However, if you want to apply initial filtering to grid columns, you should use the FireCommandEvent method:

I hope this will prove helpful.

When I tried implementing the load event of the  I got a null reference exception - what am I missing?

Hello Hannah,

Generally, the Controls[0] approach should return the generated combo or dropdownlist control:
https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-editinsert-mode

Please note that if you are using Batch editing mode, things a little bit different:
