Page causes validation errors when navigating to another page

Hi,

I have a couple of pages with standard asp.net validation controls such as RequiredFieldValidator etc inside my RadAjaxPanel.

As soon as I navigate to another tab in my RadTabStrip the page seems to force validation errors and pretty much "locks" the page even though non of the fields was selected to enter data.

Only once all the required fields was entered the page seems to release the "lock" and only then am I able to navigate to another tab / page without even submitting the page.

Any idea what might be causing the "lock" and forced validation errors on the page?

Thanks

Image alignment problem

The alignment box on the image editor doesn't seem to be working in my rad editor the popup appear but clicking on it has no effect. The control in the set image properties button seems to work fine though.

I get a Javascript error this.getPopupVisibilityController() is null or not an object on lines 2383, 2179 (several times each) which I assume may be part of the problem.

Any ideas?

Newbie Q: How do I read a label from a grid in javascript?

Hi,

Please excuse the level I'm posting in these forums at, I'm rather new to asp.net let alone telerik controls.

Basically, I have created a radgrid, in this radgrid is the following column template:

[code]
   <telerik:GridTemplateColumn UniqueName="completedDateTime" HeaderText="Completed Date & Time">
   <ItemStyle HorizontalAlign="Center" />
   <ItemTemplate>
   <asp:Label ID="lblCompletedDateTime" runat="server"></asp:Label>
   </ItemTemplate>
   </telerik:GridTemplateColumn>
[/code]

What I want to do basically is onrowselect - read the TEXT property of lblCompletedDateTime in javascript.

I usually refer to the clientid or the rendered id of the label (using $find) but I obviously need to identify it per row which is where I'm stuck.

Thanks a lot!!

Dan

p.s. Sorry about the code there!? Thought they were the code tags.

Rendering issue in multi-column mode

Hello

we are using the RadMenu component in multi-column disposition (3 columns), and we are facing a minor rendering issue on some child menus as shown in my screenshot:

If you show a child menu of an item of the first column, there is no issue. If you show a child menu of an item of the second or third columns, the left border of the child menu item is not correctly rendered. It looks as if it was trying to display the menu item's image although we did not set any image. So we get a blank square.
This issue occurrs ate least with IE, FF and Chrome

Regards

Menu

Advanced Form Template and Recurrence Rule Editor

Hi,

I am using a Scheduler setup as demonstrated in http://demos.telerik.com/aspnet-ajax/scheduler/examples/advancedformtemplate/defaultcs.aspx

Our users are complaining that when making an "all day" recurring appointment, they can still select "hourly" from the recurrence rule editor (see attached screen shot)

Is there any workaround to this?

Best Regards,
Konrad

            if (_selectedItems != null) {
                var oldSelected = _selectedItems.get_masterTableView().get_selectedItems();
                for (var i = 0; i <= oldSelected.length - 1; i++) {

           _selectedItems.get_masterTableView().get_selectedItems()[i].set_visible(false)
                   _selectedItems.get_masterTableView().get_selectedItems()[i]._selected = false;

Adjusting RadWindow size on client action issues

Hi Telerik,

I have a RadWindow of a certain size. When the RadWindow is first loaded I call AdjustRadWindow to set the window size. In addition, the window adjusts fine on a RadDateTimePicker's OnPopupOpening and OnPopupClosing events.

I am struggling to get this to work when the user interacts with a RadComboBox. The RadComboBox hides elements on the RadWindow and I would like to resize the window after they're hidden.

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

SetWindowState(RadComboBox1.SelectedValue);

}

private void SetWindowState(string currentSelection)

{

if (string.Compare(currentSelection, Charts.LineChart.ToString()) == 0)

{

RadDateTimePicker2.Visible = true;

Label2.Visible = true;

CheckBox3.Visible = true;

}

else if (string.Compare(currentSelection, Charts.PieChart.ToString()) == 0)

{

RadDateTimePicker2.Visible = false;

Label2.Visible = false;

CheckBox3.Visible = false;

}

else

{

Debug.Assert(false, "Unhandled chart type in RadSettings");

}

function OnClientSelectedIndexChanged(sender, eventArgs) {

setTimeout(function () { AdjustRadWindow(); }, 500);

}

function AdjustRadWindow() {

var oWindow = GetRadWindow();

setTimeout(function () { oWindow.autoSize(true); if ($telerik.isChrome || $telerik.isSafari) ChromeSafariFix(oWindow); }, 500);

}

//fix for Chrome/Safari due to absolute positioned popup not counted as part of the content page layout

function ChromeSafariFix(oWindow) {

var iframe = oWindow.get_contentFrame();

var body = iframe.contentWindow.document.body;

setTimeout(function () {

var height = body.scrollHeight;

var width = body.scrollWidth;

var iframeBounds = $telerik.getBounds(iframe);

var heightDelta = height - iframeBounds.height;

var widthDelta = width - iframeBounds.width;

if (heightDelta > 0) oWindow.set_height(oWindow.get_height() + heightDelta);

if (widthDelta > 0) oWindow.set_width(oWindow.get_width() + widthDelta);

oWindow.center();

}, 310);

}

If I place an alert inside of OnClientSelectedIndexChanged then, after I close the alert, AdjustRadWindow seems to work properly. The problem is that the controls aren't disappearing fast enough from the screen, even with two time-outs.

I believe the issue may be related to this -- http://www.telerik.com/community/forums/aspnet-ajax/ajax/slow-ajax-response-wondering-if-i-can-do-something-to-improve.aspx

Any suggestions? Solutions?

Thanks

Minimize zone not honored on page load

I have a RadWindow declared with

VisibleOnPageLoad="True"
MinimizeZoneID="CatalogZone"
InitialBehaviors="Minimize"
Behaviors="Move,Minimize"
KeepInScreenBounds="True"
OffsetElementID="CatalogZone"

It does not honor the minimize zone on page load. Once I manually restore and minimize the window, it works properly. How can I get it to display in the minimize zone on initial page load?

No PageSize Controls

What could cause Advanced paging to not work?

<telerik:RadGrid ID="grdTicket" runat="server" AutoGenerateColumns="false" Width="946px" Font-Names="Verdana" Font-Size="x-small" EnableViewState="true"

AllowSorting="true" AllowPaging="true" AllowMultiRowSelection="false" OnNeedDataSource="grdTicket_NeedDataSource" OnPageIndexChanged="grdTicket_PageIndexChanged" >

<MasterTableView Width="100%" NoDetailRecordsText="No Records To Display">

<Columns>

<telerik:GridBoundColumn DataField="origdtdate" HeaderText="Call In Date" ReadOnly="true" SortExpression="origdtdate"></telerik:GridBoundColumn>

<telerik:GridHyperLinkColumn DataTextField="ticketnum" HeaderText="Ticket#" SortExpression="ticketnum" DataNavigateUrlFields="ticketnum" DataNavigateUrlFormatString="SearchViewTicket.aspx?ticketnum={0}"></telerik:GridHyperLinkColumn>

<telerik:GridBoundColumn DataField="address" HeaderText="Address" ReadOnly="true" SortExpression="address"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="street" HeaderText="Street" ReadOnly="true" SortExpression="street"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="city" HeaderText="City" ReadOnly="true" SortExpression="city"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="county" HeaderText="County" ReadOnly="true" SortExpression="county"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="company" HeaderText="Contractor" ReadOnly="true" SortExpression="company"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<PagerStyle Mode="NextPrevNumericAndAdvanced" ShowPagerText="true" />

</telerik:RadGrid>

The above PagerStyle outputs NextPrevAndNumeric controls, there are no advanced controls. If I change mode to Advanced, nothing shows up in the footer. I'm using 2010 Q1, but I've also updated to 2011 Q1 and get the same results.
