Hello all,

I setup a vertical CoverFlow RadRotator in a user control bound to a generic List<> but i cant seem to get the rotator to "wrap" using WrapFrames="true" and i only get 1 cycle of the items in the List<>. I've tried changing the binding to IEnumerables and string[].
For this example, the List<> is just List<string> vpaths.

Heres the markup for the rotator.

<

telerik:RadRotator ID="rotatorVerticalMediaItems" runat="server" Height="400px" Width="400px" CssClass="ucCoverArtRotatorV_RotatorStyle" RotatorType="CoverFlow" PauseOnMouseOver="false" Skin="Black" ScrollDuration="2000" ScrollDirection="Down,Up" FrameDuration="1" ItemHeight="300px" ItemWidth="202px" WrapFrames="true">

</div>

</ItemTemplate>

</telerik:RadRotator>

Thanks in advance.

Grid getting disappeared on updating any of the rows information

Hello,
I'm using the telerik grid but when I try to update any of the information, the grid disappears completely. Following are the steps I follow:
1. Click on the 'Edit' button for any of the row and update any information.
2. Press Update button.

As soon as I press 'Update' button, grid disappears. And when I reload the page, it appears again.
Following is the html code:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="tgLicenseInfo">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="tgLicenseInfo" LoadingPanelID="RadAjaxLoadingPanel1" />

// oLI.LState = drdState.SelectedItem.Value;

oLI.LState = txtState.Text;

//here license is saved

ProcessResult oPR = oLI.Save(this.CnxnString, this.LogPath);

if (oPR.Exception == null)

{

oUser.AgentInProcess.LicenseInfo[iLID] = oLI;

Cache[this.GUID + "User"] = oUser;

this.tgLicenseInfo.Rebind();

}

// else

// this.lblUpdate.Text = "Error:" + oPR.Exception.Message;

}

catch (Exception Exc)

{

string script = "$(function(){initializedialog();showDialog(\"" + Exc.Message + "\");});";

ScriptManager.RegisterStartupScript(this, this.Page.GetType(), "dialog", script, true);

}

Can some one help me with this issue?

Menu and vavigation blocking

Hi,

We are working on a rich ASP.Net application using most of Telerik controls and we are facing a strange issue. Given below is the scenario:

1. User visits our site.
2. Navigates to different pages using different Menu options (RadMenu - on Top of page, RadPanelBar - on Left).
3. in the same browser window/tab, User opens any other website e.g. msn.com.
4. Now, user moves back to previous page (our website) using browser's back button.

Once user is back on our website, both left and top menu bars are not functional i.e. clicking on menu items performs no action. Clicking or double clicking a menu makes no difference. It start behaving in a way that if there is no Page linked to any of the menu.

What could be the reason? Any fixes/help?

We are using RAD Asp.Net AJAX Q2 2011

Thanks in acticipation!

Can't see control from another tab

OK, I just inherited a project that uses these controls and I am not sure how to word this. I have a page thatuse radtabstrip and multipage. I have several pages and when I click on to save, the tables are getting updated with all the values with the first tab and doesn't see anything else. I also get the identity of the record and save it as a session variable for a child table and it doesn't see it either. Is it possible for me to see the controls on all the tabs? If so, how do I do it?

Setting SelectedDate on RadDateTimePicker but leaving it Empty on Page_Load

I have a RadDateTimePicker that needs to stay empty when the page loads. When the user selects a time from the TimePopupButton, the Date & Time are populated in the RadDateTimePicker. The problem is the date portion that's populated is always today's date. How can I default this to another date, for example DateTime.Now.AddDays(1)?

If I set the "SelectedDate" property to DateTime.Now.AddDays(1), then the date that's populated works as expected. But setting "SelectedDate" causes the RadDateTimePicker to display this date when the page loads. I need it to be empty on page load and only populated if the user selects something from the PopUpButtons.

Cross-site Script vulnerability in WebResource.axd

We have found a Xss vulnerability in the Telerik.Web.UI.WebResource.axd [_TSM_CombinedScripts_ parameter], where it is possible to edit the javascript. We are currently using an older version of the library (2009.3.1103.20). Can anyone confirm that this issue is fixed in the latest release, and in what version was this issue solved?

Any way to selectively filter on client side?

I'm not even sure this can be done, but here goes:

What I am trying to do is avoid database hits on every character entered in a Load-On-Demand RadComboBox. When one character is entered, I go to the database and get the resulting dataset. Any further characters entered will filter that same dataset. The only time the database is accessed is when the first character is entered. Is this even possible? If so, any pointers?

Grouping: customizing the look

Hi,

The look of grouping (in the data area of a grid) consists of three elements:

the group header
the cell to the left of the group header, containing icons for expanding / collapsing; let's name it "the control cell"
cells the the left of data rows; let's name them "filling cells"

I'm using the Simple skin and Q1 2010 version of the controls.
All these elements have initially the same, darkgray background. The control cell (and its column) is quite wide. I would like to change two aspects of their look:

the back color of all of them
the width of the control cell and the filling cells

I tried to use GroupHeaderItemStyle. Changing its BackColor changed the back color of the header and the filling cells - but the control cell remained untouched. Changing its Width changed nothing.
I tried to modify Grid.Simple.css file. I've succeeded in changing the back color of all the required elements. But I cannot make the column with the control and filling cells narrower. The MasterTableView is rendered with the "colgroup" element wich contains 20px width of this column. This is the key - is it possible to me to change this value?

Regards
Tomasz
