Adding RadDateTimePicker dynamically.

[jayakumar chinnappa]

Hi Team,

the first issue i am facing is how do i add the RadDateTimePicker dynamically from the code behind. I tried putting the control using the following piece of snippet.
 cntrlType = webControls.GetType("Telerik.Web.UI.RadDateTimePicker");
                            objCntrl = Activator.CreateInstance(cntrlType);
                            ((Telerik.Web.UI.RadDateTimePicker)objCntrl).ID="datetimePicker";
                            this.Controls.Add((Telerik.Web.UI.RadDateTimePicker)objCntrl);
after adding this from the code behind it is displaying the date and time button, however on clik of those button no go.
Kindly help us.

thanks,

Hello Jayakumar,

If you are creating the RadDatePicker dynamically in another control event such as a button, then you can store a value in the ViewState on the button click once the control is created.

protected void Button1_Click(object sender, EventArgs e)
    {
          // create datepicker
          ViewState["control"] = "ControlAdded";  // setting a flag
    }

Then in the Page_Init event, you can check for the ViewState value and then recreate the control again:

protected void Page_Init(object sender, EventArgs e)
    {
        if (ViewState["control"] != null)
        {
            if (ViewState["control"].ToString() == "ControlAdded")
            {
                //create datepicker
            }
        }
    }

Thanks
Princy.

Hello Jayakumar,

I would suggest you to modify your code like this:

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
    <asp:PlaceHolder runat="server" ID="PlaceHolder1"></asp:PlaceHolder>

Code-behind:

protected void Page_Init(Object sender, EventArgs e)
   {
       object objCntrl = Activator.CreateInstance(typeof(RadDatePicker));
       ((Telerik.Web.UI.RadDatePicker)objCntrl).ID = "datetimePicker";
       PlaceHolder1.Controls.Add((Telerik.Web.UI.RadDatePicker)objCntrl);
   }

I hope this helps,
