Hello,

For achieving the required functionality I would suggest you to access the TimePicker controls and apply the validation logic demonstrated in this online example .
As for the coloring of the invalid input, you could simply handle its OnError client event and set a border color for the input.

Hello,

You can attach the client event OnDateChanged to the TimePicker and pass the Client ID of the RadTimePicker. Then from client side access the controls, calculate the time difference from there.
Here is a sample code:
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)//edit mode is editform/popup
       {
           GridEditFormItem item = (GridEditFormItem)e.Item;
          RadTimePicker pkr=(RadTimePicker)item.FindControl("RadTimePicker1");
          RadTimePicker pkr2 = (RadTimePicker)item.FindControl("RadTimePicker2");
           
          pkr.ClientEvents.OnDateSelected = "function (button,args){OnDateSelected('" + pkr.ClientID + "','" + pkr2.ClientID +"');}";
          pkr2.ClientEvents.OnDateSelected = "function (button,args){OnDateSelected('" + pkr.ClientID + "','" + pkr2.ClientID +"');}";
       }
   }

JS:
function OnDateSelected(pkr1, pkr2)
    {
    // access the control and set the label value
   }

You can find more on RadTimePicker client side API from here.
RadTimePicker Client Object.

Hello,

If you are accessing the picker control in ItemDataBound event as I have suggested and then you passed them as parameters for the "OnDateSelected" function  you could directly use them on the client as the event senders.
Therefore please instead of trying to access the pickers in the RadGrid control, use them directly and see if the selected date is accessible.

Hi Jaswant,

The described behavior is not a built-in feature/functionality of the controls, therefore, you will need to implement it on your own. You can take advantage of the client-side events of the control to execute your logic at an optimal time.

Below I will show you one example you can achieve this or similar behavior. You can use this a base concept, and adjust it further if needed.

HTML Markup

You can take advantage of the PopupOpening event of the DateTimePicker or TimePicker, which fires before the TimeView is opened. Wire up this event to the control.

<telerik:RadDateTimePicker ID="RadDateTimePicker1" runat="server"
    TimeView-Interval="0:1:0">
    <ClientEvents OnPopupOpening="OnPopupOpening" />
</telerik:RadDateTimePicker>

JavaScript

In the OnPopupOpening event handler, you can then access the HTML elements of the TimeView, get access to their values, try converting the values to Date type then compare those with the current time. If Cell's time is less then the current time, disable the links, stop the execution of event handlers.

function DisableEvent(e) {
    // cancel the event
    e.preventDefault();
    // stop the event from bubbling up to its parent elements
    e.stopPropagation();
}
 
function OnPopupOpening(sender, args) {
    // reference to the TimeView element
    var timeView = args.get_popupControl();
    // iterate through the Table cells
    $(timeView.get_element()).find('td').each(function (i) {
        var cell = $(this);
        var cellText = cell.text().trim();// reference to the cell's text value
        var cellTime = cellText.split(" ")[0];// time part of the Cell's value
        var cellHour = parseInt(cellTime.split(":")[0]);// Hour part
        var cellMinutes = parseInt(cellTime.split(":")[1]);// Minutes part
        var isPM = cellText.indexOf("PM") >= 0 ? 12 : 0;// some code to verify whether it is AM or PM time
        if (isPM && cellText.startsWith("12:")) {
            isPM = 0;
        }
        var pastTime = new Date(); // create new Date object
        pastTime.setHours(cellHour + isPM); // set date object hours to the cell's hours
        pastTime.setMinutes(cellMinutes); // set date object minutes to the cell's minutes
 
        var currentTime = new Date(); // create new Date object
        if (pastTime < currentTime) { // compare past Time with current Time
            disableTimeViewCell(cell); // method to disable events such as click, hover, etc..
            // additional styling
            cell.find("a").css("color", "#F1F1F1");
            cell.css("cursor", "not-allowed");
        }
    });
}
 
function disableTimeViewCell(cell) {
    cell.find("a").removeAttr("href"); // remove href attribute of the A element
    cell.on('mousedown mouseup click mouseover mouseout', DisableEvent); // attach event Listeners for some of the events
}

I hope this will prove helpful.

Kind regards,
Attila Antal
