Hi,

I am displaying couple of images inside the RadRotator. The RotatorType is Carousel. I want to set the image focus when the user mouseover any image inside the RadRotator. The OnClientMouseOver method works only when I mouseover any other control in my page and then mouseover the RadRotator Item (which in this case is an Image).

How do I fix this problem? I want the ability to set the currentItemIndex as soon as the I mouseover any item(s) within the RadRotator.

Thanks for your help.

Filter menu appearing behind Radgrid

I have a LinkButton that i am using to activate a tooptip that is displaying a RadGrid of items. When i try to filter the items in the Radgrid the filter menu displays behind the grid. Any help would be appreciated.

Issue with data entry in RadMaskedTextBox. Cursor moves to end of mask.

Hi,

Has anyone else got a problem with entering data into a RadMaskedTextBox in IE6 with the latest version of the controls (Version: 2011.1 413 (Apr 13, 2011))?

What it's doing is when ever I hit the first number key it moves the cursor to the end of the mask. I then have to cursor key back to the second character entry and repeat until I've filled in the require data. The data it's taking is time entry i.e. 09:00-12:00 with a mask of ##:##-##:##

To replicate just drop a RadMaskedTextBox to a page (with a RadScriptManager), and configure as below.

Default.aspx

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadMaskedTextBox ID="txtShift" runat="server" MaxLength="11" Width="60px" Mask="##:##-##:##" SelectionOnFocus="SelectAll" >

</telerik:RadMaskedTextBox>

This will allow you to repeat it in IE6. This does not happen in IE8, or IE9.

Regards
Nick

RadRotator : Problem with button mode & WrapFrames = false

Hi,

I found a strange behavior using your example here : http://demos.telerik.com/aspnet-ajax/rotator/examples/default/defaultcs.aspx

Take the 'Buttons' rotatortype and untick the WrapFrames box (WrapFrames="false")

As you can see, you can only see 8 pictures, the last 2 won't show.

Now take the 'ButtonsOver' rotatortype, and you will be able to see all the pictures (10).

It seems that the last frame is never shown in buttons mode in some cases :

If you set Width (px) : 364px (value for 3 pictures + navigating arrows in your example), you will see the first 3 pictures on page load, then 4 to 6 on first click, then 7 to 9 on second click, but you will not see the last picture : if the last frame is not entirely 'filled', its not shown.

Is there something I don't set up correctly ?

Thank You
Arnaud

Grid - Scrolling and filtering

Hi All,

I need Horizontal scroll on gridview.is it mandatory to Set UseStaticHeaders property to true .

Also any option in RAD grid filtering similar to excel sheet.

The filter boxes require me to type in a value to filter on. Is there an option for something closer to how Excel handles filters?

Thanks

RadSpell sharing Custom Dictionary File suggestions

Hi guys,

we have been implementing the RadSpell control within a number of large forms, both from within the RadEditor using the 'abc' spell-check button, and using a client-side 'mass-input' javascript function which combines all the fields on the forms and checks accordingly.

All has been working as expected, with a single tdf master dictionary file and allowing each user to add to a separate custom file with their username as the suffix.

One thing we have noticed though, when a user adds a custom word to their dictionary, it is displayed as a 'suggestion' for anyone else who tries to enter the same word.

I have tried this on your demonstration page of the website, and adding the english "theatre" to en-US-John.txt, when you enter the "theatre" and check using en-US-Sally.txt, although the word had not been added, it is still a suggestion.

If you wish to test, this also happens with other words we have used locally, and yet to add to the demo site ("colour", "analyse" etc)

Is this by design, or is it an issue with the spell-engine caching data? The concern arises by the fact that users could add incorrectly spelt words to their custom file, which would then be shown as a suggestion to all other users and could multiply any mistakes.

Look forward to hearing back about any resolution.

Could not load file or assembly 'Telerik.Web.UI' or one of its dependencies. There is not enough space on the disk.

Hello,

I've developed my web app with Telerik ASP.NET AJAX libraries; when build my app (without errors) and deploy it on IIS obtain this error:

"Could not load file or assembly 'Telerik.Web.UI' or one of its dependencies. There is not enough space on the disk."

An unhandled exception was generated during the execution of the
            current web request. Information regarding the origin and location of the
            exception can be identified using the exception stack trace below.

I've search on Google; I've change quota disk for IIS User, but the results don't change.

Where is the error?

Thanks.

M.

Fail to find combo

Hi,

I have this piece of code:

<script type="text/javascript">

function setEmpty()

{

var combo = $find("<%= combo1.ClientID %>");

combo.clearselection();

combo.set_emptyMessage("select please");

}

function nodeClicking(sender, args) {

var comboBox = $find("<%= combo1.ClientID %>");

var node = args.get_node()

comboBox.set_text(node.get_text());

comboBox.trackChanges();

comboBox.get_items().getItem(0).set_text(node.get_text());

comboBox.get_items().getItem(0).set_value(node.get_value());

comboBox.commitChanges();

comboBox.hideDropDown();

// Call comboBox.attachDropDown if:

// 1) The RadComboBox is inside an AJAX panel.

// 2) The RadTreeView has a server-side event handler for the NodeClick event, i.e. it initiates a postback when clicking on a Node.

// Otherwise the AJAX postback becomes a normal postback regardless of the outer AJAX panel.

//comboBox.attachDropDown();

}

function StopPropagation(e) {

if (!e) {

e = window.event;

}

e.cancelBubble = true;

}

function OnClientDropDownOpenedHandler(sender, eventArgs) {

var tree = sender.get_items().getItem(0).findControl("rvt1");

var selectedNode = tree.get_selectedNode();

if (selectedNode) {

selectedNode.scrollIntoView();

}

</script>

<telerik:RadComboBox ID="combo1" runat="server" CausesValidation="false"

EnableEmbeddedSkins="false" OnClientDropDownOpened="OnClientDropDownOpenedHandler"

EmptyMessage="select please" MaxHeight="200px" ShowToggleImage="True"

Width="50%" AllowCustomText="True">

<ItemTemplate>

<div id="div1">

<telerik:RadTreeView ID="rvt1" runat="server" Width="100%" Height="250px"

DataSourceID="ds1" DataFieldID="ID" DataValueField="ID"

DataFieldParentID="ParentID" DataTextField="Name" OnClientNodeClicking="nodeClicking" >

<DataBindings>

<telerik:RadTreeNodeBinding Expanded="true" />

</DataBindings>

</telerik:RadTreeView>

</div>

</ItemTemplate>

<Items>

<telerik:RadComboBoxItem Text="" />

</Items>

</telerik:RadComboBox>

<asp:ObjectDataSource ID="ds2" runat="server"

EnablePaging="True" OnSelecting="dds2_Selecting"

SelectMethod="GetList" TypeName="BLL">

<SelectParameters>

<asp:Parameter Name="p1" Type="Int32" />

<asp:Parameter Name="p2" Type="Int32" />

<asp:Parameter Name="p3" Type="Boolean" DefaultValue="True" />

</SelectParameters>

</asp:ObjectDataSource>

The combobox is inside a panel. When I show the panel, I call the function setEmpty() to clear the previous data. The problem is that I get a javascript exception. Debugging, I realize that the that the find("<%combo1.ClientID %>"); is returning null... ie it is not able to find the combo1.ClientID. The strange thing is that the function nodeClicking is working, ie, when I click in a node, the nodeClicking function is properly executed... The only problem is with tje setEmpty() function.

Issue with RadAjaxLoadingPanel

Hello,

In our application, we have a scenario where we need to handle multiple ajax postbacks executing in parallel. We have set "RequestQueueSize" of the Ajax Manager to 10 to accomplish this,

After doing so, We found a problem when we tested the scenario outlined below :

We have 2 combos(Say combo1 and combo2) on a page, both of which cause postbacks to populate different fields . We executed the following steps:

1. choose a value in combo1. Combo 1 posts back to fetch and populate related values on our page
2. change the selected value in combo1. While its postback is executing, choose a value in combo2.

On doing this we found both postbacks execute successfully. But After combo2's postback finishes executing, the state of combo1 is restored to what it was after step1 above.

Any help with solving this problem would be greatly appreciated.
Thank you
