A user has the power to select their language and on save, updates every control on the screen. 

I am not seeing the text within a RadTabStrip is being updated. 

My code is simialr to below:

I locate the tab in question, and assign the text within Page_Load. 

            Dim myTab As RadTab = WindowTabs.Tabs.FindTabByValue("SomeTab")
            myTab.Text = GetLabelBasedOnSelectedLanguage(myTab) ' this returns the proper value 

I can see myTab.Text now holding the proper value BUT on the screen there is no change. 

Is there a way to update the text on the fly via server side?

thank you 

Is there a way to access ItemsPerRequest parameter value on the client side?

Hi Team,

I have RadGrid filter with timepicker. How to get value in timepicker with javascript.

My code

<asp:GridTemplateColumn UniqueName="ArrivalTime" DataField="ArrivalTime"
                                    HeaderText="Visit Date" HeaderStyle-Width="20%">
    <FilterTemplate>
                                        <asp:RadTimePicker RenderMode="Lightweight"
                                            ID="rdpArrivalTime" runat="server" Width="99%"
                                            ClientEvents-OnDateSelected="ArrivalTimeDateSelected"
                                            DbSelectedDate="<%# SetArrivalTime(Container) %>" />
                                        <asp:RadScriptBlock ID="rsbArrivalTime" runat="server">
                                            <script type="text/javascript">
                                                function ArrivalTimeDateSelected(sender, args) {
                                                    var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
                                                    var date = FormatSelectedDate(sender);
                                                    tableView.filter("ArrivalTime", date, "EqualTo");
                                                }
                                                function FormatSelectedDate(picker) {
                                                    var date = picker.get_selectedDate();
                                                    var dateInput = picker.get_dateInput();
                                                    date.setHours(date.getHours() + 1);
                                                    date.setMinutes(date.getMinutes());
                                                    var formattedDate = dateInput.get_dateFormatInfo().FormatDate(date, dateInput.get_displayDateFormat());
                                                    return formattedDate;
                                                }
                                            </script>
                                        </asp:RadScriptBlock>
   </FilterTemplate>
   <ItemTemplate>
           <%# !Eval("ArrivalTime").Equals(DateTime.MinValue) ? string.Format("{0:hh:mm tt}",Eval("ArrivalTime")) : "" %>
   </ItemTemplate>
</asp:GridTemplateColumn>

<telerik:RadComboBox ID="ddlLocation" runat="server" DropDownHeight="100px" CheckedItemsTexts="DisplayAllInInput"  EnableCheckAllItemsCheckBox="true"
                                Localization-CheckAllString="All" Localization-AllItemsCheckedString="All"  onitemchecked="OnItemChecked"                                  OnCheckAllCheck="ddlLocation_CheckAllCheck" CheckBoxes="true"  EmptyMessage="--Select--" Height="200px" AutoPostBack="true"/>

I have a RadComboBox with the checkboxes active. I want to have a postback for the ItemChecked event.
The combobox also is generating a postback on closing of the dropdown which I do not want. How can I prevent this to happen.

Hi,

First thanks for your great support.

Currently I want to fill RadDropDownList control with items from the client side.

I am able to add them, but I am not able to add a tool tip against them. Is it possible this to be achieved?

var radDropDown = $find("<%= ddlOptions.ClientID %>");
var item = new Telerik.Web.UI.DropDownListItem();
item.set_value("1");
item.set_text("Option 1");

//maybe in some way here I need to add a tooltip option

radDropDown .get_items().add(item);

So I saw one of the old thread by Princy:

https://www.telerik.com/forums/find-control-within-itemtemplate-client-side

I tried that in my lightbox but it seems is not setting the value of the textbox in the itemtemplate of the lightbox, why ?

        function OpenLB() {
            var lightBox = $find('<%= LBoxEdit.ClientID %>');
            lightBox.show();
            var Text = lightBox.get_element().getElementsByClassName("rltbDescriptionBox");
            Text.LBoxEdit$txtDescripton.control.set_value("new value");
        }

            <telerik:RadLightBoxItem>
                <ItemTemplate>
                    <table style="padding: 20px; font-family: Arial">
                        <tr>
                            <td style="font-family: Arial, Helvetica, sans-serif; font-size: 18px; padding-bottom: 10px;">
                                Description
                            </td>
                        </tr>
                        <tr>
                            <td style="padding: 10px 0px 10px 20px">
                                <telerik:RadTextBox ID="txtDescripton" runat="server" CssClass="rltbDescriptionBox" Font-Size="16px" Width="400px" Height="30px">
                                </telerik:RadTextBox>
                            </td>
                        </tr>
                        <tr>
                            <td style="padding: 10px 0px 10px 20px">
                                <telerik:RadButton RenderMode="Lightweight" ID="btnFormSave" Height="30px"
                                    Text="Save" Font-Size="16px" Font-Bold="True" runat="server" Skin="Silk"></telerik:RadButton>
                            </td>
                        </tr>
                    </table>                    
                </ItemTemplate>
            </telerik:RadLightBoxItem>

So I have a a RadDatePicker declared thus: 

protected global::Telerik.Web.UI.RadDatePicker rdpEndDT;

And I am using it in code thus: 

                    rdpEndDT.SelectedDate = // some date;
                    rdpEndDT.MinDate = // some other date.;
                    rdpEndDT.MaxDate = // yet another date;

I have a stack trace error of the following form: 

Cause: ArgumentOutOfRangeException 
Cause Description: Value of '1/10/2018 12:00:00 AM' is not valid for 'SelectedDate'. 'SelectedDate' should be between 'MinDate' and 'MaxDate'. 
Parameter name: SelectedDate 
Cause Stack: 
at Telerik.Web.UI.RadDatePicker.set_SelectedDate(Nullable`1 value) 
at Telerik.Web.UI.RadDatePicker.set_MaxDate(DateTime value) 

What is this stack trace telling me? 

Is the complaint on this line: 

  rdpEndDT.MaxDate = // yet another date;

but if it is, given that I'm changing the max date, why should this exception be raised? At this point in the process max date is default of 2099; it is being set to a lower value in this code branch.  Why should max date refuse to permit itself to be changed?

Or is the complaint on this line: 

rdpEndDT.SelectedDate = some date

which would occur if I was trying to programmatically set a selected date later than the max date. But if this is so, why is set_MaxDate mentioned in the stack trace? 

Respectfully, 

Brian P.
