[Solved] RadDatePicker in Grid EditFormSettings - how to get selected date ?

[Krzysztof]

Hi
I have :

<telerik:RadGrid ID="GridAdvert" runat="server" >
         <MasterTableView DataKeyNames="id" >
           <EditFormSettings EditFormType="Template"  >
            <EditColumn UniqueName="EditCommandColumn1">
            </EditColumn>
             <FormTemplate>
                  <telerik:RadDatePicker runat="server" ID="PickerTimeFrom"
                    SelectedDate='<%# DataBinder.Eval( Container, "DataItem.timeFrom" ) %>' >

                  </telerik:RadDatePicker>

             <asp:Button ID="UpdateButton" OnClientClick="Save(this, event);" Text="Save"
                    runat="server" />
            </FormTemplate>
           </EditFormSettings>
          </MasterTableView>
         </telerik:RadGrid>

in JavaScript block :

function GetGridServerElement(serverID, tagName)
            {
                if (!tagName)
                    tagName = "*"; //* means all elements

                var grid = $get("GridAdvert");
                var elements = grid.getElementsByTagName(tagName);
                for (var i = 0; i < elements.length; i++)
                {
                    var element = elements[i];
                    if (element.id.indexOf(serverID) >= 0)
                        return element;
                }
            }

function Save(sender, e)
{

  var xx = GetGridServerElement("PickerTimeFrom","");

  var firstDatePicker = $find(xx.id); <<<<<<<<<<< Problem !!!!!
  var dateToNavigate = firstDatePicker.get_selectedDate();


}

I have a problem with $find("PickerTimeFrom"). After this I get null.
I would like to call firstDatePicker.get_selectedDate() for selected date. I do not know why ?

Hello Krzysztof,

Please take a look at the following code-snippet:

<FormTemplate>
    <telerik:RadDatePicker runat="server" ID="PickerTimeFrom" SelectedDate='<%# Eval("OrderDate") %>'>
    </telerik:RadDatePicker>
    <asp:Button ID="UpdateButton" OnClientClick="Save(this, event);" Text="Save" runat="server" />
</FormTemplate>

<script type="text/javascript" language="javascript">
    function Save(sender, args)
    {
        var datePicker = $telerik.findControl(sender.parentNode, "PickerTimeFrom");
    }
</script>

Let me know if you need further assistance.

Hello Krzysztof,

Please examine the attached example and let me know whether it helps.

Note that in order to find a control with the findControl method you need to supply a parent element.

findControl(parent_html_element, controlID);

I hope this helps.
