RadDatePicker Clearing Problem

[Renan]

Hi All,

We are having some difficulties on clearing RadDatePicker selected values. We have multiple RadDatePicker on our page and we want to clear its selected date to NULL or empty its input box, we already tried filtering RadDatePicker, DatePickingInput and RadDateInput with no success.

"No problem on JavaScript but we need to do it on server side"

Sample Code:

public void ResetFormControlValue(Control parent)
{
    foreach (Control c in parent.Controls)
    {
        if (c.Controls.Count > 0)
        {
            ResetFormControlValue(c);
        }
        else
        {
            switch (c.GetType().ToString())
            {
                case "Telerik.Web.UI.RadNumericTextBox":
                    break;
                case "Telerik.Web.UI.RadTextBox":
                    break;

                case "Telerik.Web.UI.DatePickingInput": // Clear all RadDatePicker
                    ((RadDateInput)c).Clear();
                    break;
            }
        }
    }
}

Thanks for any help!

Hello Renan,

Try clearing the DatePicker using its ID.
C#:

case:Telerik.Web.UI.RadDatePicker:
RadDatePicker1.Clear();

Thanks,
Princy.

Hi Princy,

Thank you for your reply. What i did is to get the control ID and use FindControl(). In this way, I am not tied on specific control name, because, we have Nth DapePicker on our page.

Again, thanks for your response.

Final Code:

public void ResetFormControlValue(Control parent)
    {
        foreach (Control c in parent.Controls)
        {
            if (c.Controls.Count > 0)
            {
                ResetFormControlValue(c);
            }
            else
            {
                switch (c.GetType().ToString())
                {
                    case "Telerik.Web.UI.RadNumericTextBox":
                        ((RadNumericTextBox)c).Value = 0;
                        break;
                    case "Telerik.Web.UI.RadTextBox":
                        ((RadTextBox)c).Text = "";
                        break;
                    case "System.Web.UI.WebControls.TextBox":
                        ((TextBox)c).Text = "";
                        break;
                    case "Telerik.Web.UI.RadComboBox":
                        ((RadComboBox)c).SelectedIndex = 0;
                        break;
                    case "Telerik.Web.UI.RadComboBoxItem":
                        ((RadComboBoxItem)c).ComboBoxParent.SelectedIndex = 0;
                        break;
                    case "System.Web.UI.WebControls.CheckBox":
                        ((CheckBox)c).Checked = false;
                        break;
                    case "Telerik.Web.UI.RadMaskedTextBox":
                        ((RadMaskedTextBox)c).Text = "";
                        break;

                   case "Telerik.Web.UI.DatePickingInput":
                        var rdp = FindControl((c).NamingContainer.ID);
                        ((RadDatePicker)(rdp)).Clear();
                        break;
                }
            }
        }
