Changing the BackColor of a Standard Button

Here's my preliminary layout code for a simple button:

<telerik:RadButton ID="buttonReport" runat="server" AutoPostBack="true" Text="Summary" Font-Size="X-Small" BackColor="LightBlue" Icon-PrimaryIconCssClass="rbPrint" />

Why can't I set the background color?

RadDatePicker with CustomValidator

Hello,

I was attempting to use a CustomValidator with a RadDatePicker and the validation function seems not to function. The same date picker has both a RequiredFieldValidator and CustomValidator. What I'm finding is that the custom validation client script is never fired. I'm not getting any javascript function errors either. The required field validator does however fire and properly prevents postback.

Code basically looks like this

<telerik:RadDatePicker runat="server" ID="dpkStart" Culture="<%# vRIS.Business.Utility.DateFormatProvider.RISCulture %>" MinDate="<%# DateTime.Now.Date %>" SelectedDate="<%# DateTime.Now.Date %>" />
<asp:RequiredFieldValidator runat="server" ID="StartSearchingValidator" EnableClientScript="True" ControlToValidate="dpkStart" ValidationGroup="Availability" Display="Dynamic" Enabled="true" ErrorMessage="Search beginning is required" SetFocusOnError="True" />
<asp:CustomValidator ID="valChecks" ControlToValidate="dpkStart" EnableClientScript="true" Enabled="true" ValidationGroup="Availability" Display="Dynamic" ClientValidationFunction="selfScheduleAvailability.validateAvailabilitySelection" ErrorMessage="Please select an availability day/time" runat="server"></asp:CustomValidator>

------- In a top level control, the submit button can be found.
<Portal:SubmitButton ID="btnAdvToConfirmation" Text="Schedule" OnClick="btnAdvToConfirmation_Click" ValidationGroup="Availability" CausesValidation="true" Width="130" runat="server" />

RadGrid & when EditMode is on Batch issue/bug

Currently I'm facing a RadGrid issue/bug where I'm unable to bring up the correct Edit input row.
Only happen if holding down your mouse while you click on a cell and drag away the mouse elsewhere and let go of the mouse click.

I have created an example scenario. The code is down below.
The first column is a GridTemplateColumn which contains a RadComboBox.
The second column is a GridBoundColumn.

RadGrid Settings:
<ClientSettings>
<Selecting AllowRowSelect="False" CellSelectionMode="SingleCell" />
<ClientEvents OnCellSelected="onCellSelected" />
</ClientSettings>
<MasterTableView EditMode="Batch">
<BatchEditingSettings EditType="Cell" />

Here is a scenario to reproduce the symptoms that I'm facing.
* Click on a GridTemplateColumn column cell which brings up the correct EditItemTemplate row and user can enter their input, etc.
* Click on a different GridTemplateColumn column cell and hold down your mouse while you click and drag away the mouse elsewhere and let go of the mouse click.
* Radgrid will highlight the correct GridTemplateColumn column cell however the previous EditItemTemplate row is still displays in edit mode.
* Repeat same step on to a different column.

~Any help would be greatly appreciated.

treelist not showing child items

I've verified that my parent item data matches the parent nodes, and I've nulled the parent "parent item" field so the parents show up, but no child items show up no matter what I do to tweak things.

I've read every thread I can find and this should be so simple from the demo examples.

is there some trick I'm missing that I can't find the post for?

Here's my markup:

<telerik:RadTreeList ID="RadTreeList1" runat="server" OnNeedDataSource="RadTreeList1_NeedDataSource" ParentDataKeynames="Owner" DataKeyNames="Title" AutoGenerateColumns="false" OnItemDataBound="RadTreeList1_ItemDataBound" > <Columns> <telerik:TreeListBoundColumn DataField="Title" UniqueName="Title" HeaderText="Menu Item"> </telerik:TreeListBoundColumn> <telerik:TreeListBoundColumn DataField="Owner" UniqueName="Owner" HeaderText="Parent Item"> </telerik:TreeListBoundColumn> <telerik:TreeListBoundColumn DataField="Time" UniqueName="Time" HeaderText="Children"> </telerik:TreeListBoundColumn> <telerik:TreeListBoundColumn DataField="Notes" UniqueName="Notes" HeaderText="Notes"> </telerik:TreeListBoundColumn> </Columns> </telerik:RadTreeList>

RibbonBar change image in RibbonBarSplitButton

How can I change an image on a RibbonBarSplitButton when clicks a RibbonBarButton?

<telerik:RibbonBarSplitButton Size="Large" Text="Days" Value="TypeInterval" ImageUrlLarge="~/Images/Calendar32.png">

<Buttons>

<telerik:RibbonBarButton Value="TypeCalendar" ImageUrl="~/Images/Calendar16.png" Text="Days" />

<telerik:RibbonBarButton Value="TypeTime" ImageUrl="~/Images/Time16.png" Text="Times" />

</Buttons>

</telerik:RibbonBarSplitButton>

In RadRibbonBar I use OnClientSplitButtonClicking="MenuItem".

function findSplitButton(sender, buttonValue) {

for (var i = 0; i < sender.get_tabs().get_count() ; i++) {

var tab = sender.get_tabs().getTab(i);

for (var j = 0; j < tab.get_groups().get_count() ; j++) {

var group = tab.get_groups().getGroup(j);

for (var k = 0; k < group.get_items().get_count() ; k++) {

var item = group.get_items().getItem(k);

var customAttribute = item.get_element().getAttribute('Value');

if (customAttribute != null && customAttribute == buttonValue) {

return item;

}

function MenuItem(sender, args) {

var value = args.get_button().get_value();

var button = findSplitButton(sender, 'TypeInterval');

switch (value) {

case "TypeCalendar":

button.set_imageUrlLarge("~/Images/Calendar32.png");

break;

case "TypeTime":

button.set_imageUrlLarge("~/Images/Time32.png");

break;

}

Picture does not change.

Thanks,
Oleg

1) Go to this demo https://demos.telerik.com/aspnet-ajax/colorpicker/examples/recentandcustomcolors/defaultcs.aspx
2) Click on button to open WebPalette color picker.
3) select any color and click on ok on WebPalette color picker.
4) Now click again on button to open WebPalette color picker, now you can see there by default its #808080 selected.
How can we set this default color to be the last selected color? so that next time when we open WebPalette, it should select last selected color by default.
