radgrid add new record button doesn't work

When I click on the 'Refresh' nothing happens.
When I click on the 'Add New Record' I'm getting this error:
Line: 15
Error: Sys.WebForms.PageRequestManagerServerErrorException: 'ddl_menu' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value

I'm using ASP.NET Ajax Q3 2009 NET35, v.2009, 3, 1208, 35

[Solved] Extra Blank Space in RadGrid Between Items and Header

This is occurring on a horizontaly and verically scrolled grid. I have the height set on the outer grid, not the master table.

This does not occur in the VS2010 development server, but it does show up as soon as I publish it and open the page in IE8.

It doesn't show up if I leave the PageSize at 5, if I change it to 10 or 20 it does.

I suspect this is related to why I had to remove the change PageSize control from the grid, when the size was increased it would do the same thing.

.rpLink text alignment

I am working on a RadPanelBar since upgrading to the newest version of Telerik. I have managed to fix all the other things that changed from the previous version, except for the position of the .rpLink text (the title of the link subsection) but it is currently at the top. What do I change in the css file to put this in the right position?

[Solved] Displaying rich text as plain text in radgrid column

Hi,

Does anyone know how to display a field containing text in RTF format as plain text in a radgrid column?
I'm currently using a GridTemplateColumn with a label in its ItemTemplate to display the text.
I've tried a simple GridBoundColumn, but without success.

Thanks for any suggestions.

How do I get the exact same layout/appearance as what you have in your "Rotator Blog" demo ?

Hi There !

This component is impressive, however I would like mine to look just like you have it:

http://demos.telerik.com/aspnet-ajax/rotator/examples/livexml/defaultcs.aspx

...I installed it as per the instruction on the page/link above, and it's running, but the data is scrolling with no pretty container around it (or the cool date/time color-stamps). I then applied the skins to it through the compnent properties pane, and ran the page in my .Net application again, but the blog data is still scrolling without any frame around it.

Any suggestions ? - at the endof the day, if I could get it to look like yours, it would be a happy day :-)

Cheers,

Bazz

select first row on client-server binding

I am replacing the grid in an existing page with a RADGrid
the page has a lot of functionality in a Javascript function on a select
if there is only one row I need to select it
how do I invoke the client select function from the server?
I tried this (below) - the function is hooked up but it doesn't "find" any of the objects

[Solved] searching in listbox

Hi All,

I have a Radlistbox. It has numbers in it so I have
123- TestData1
411- DataTable
789-TestData
456-EqumentData

when I type 4, I go to 411, but when I type 456, I stay at 411. Is it possible to go to 456, if I type 456. I have a huge listbox and users will not like if I stay at 411 instead of going to 456.

Any help will be appreciated.

[Solved] RadGrid Header Text Prob

Hi

In my grid view when I click on add new template I will see the following controls

Xyz (TextBox)
Abc (TextBox)
Def (TextBox)

CopyFrom (DropDown)

But When I edit the record, I want to display only

XYz
ABC
DEF

In the grid also I am not displaying CopyFrom as A column.

I tried in 2 ways but each one has their own issue which I am not able to figure it out.

First Way:

<telerik:GridTemplateColumn UniqueName="CopyTemplateColumn" Visible="false" HeaderText="CopyFrom">

<EditItemTemplate>
<telerik:RadComboBox DataSourceID="TemplateDataSourceForCopy" DataTextField="TemplateName"

DataValueField="Id" ID="ddlTargetTemplate" Width="100" Visible="true" runat="server">

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

When I am doing Visible="false" HeaderText="CopyFrom"

Prob: In the edit window also I am seeing “CopyFrom” Text since it is header text. But not seeing dropdown since I am taking care of this from code behind.

Could someone please suggest me how to hide this header text from edit window.

Second Way:

<telerik:GridTemplateColumn UniqueName="CopyTemplateColumn" Visible="false" HeaderText="CopyFrom">

<asp:Label ID="lblCopy" runat="server" Text="Copy From" ></asp:Label>

<telerik:RadComboBox DataSourceID="TemplateDataSourceForCopy" DataTextField="TemplateName"

DataValueField="Id" ID="ddlTargetTemplate" Width="100" Visible="true" runat="server">

</telerik:RadComboBox>

</EditItemTemplate>
</telerik:GridTemplateColumn>

Prob:

When I am using Label without header text.

Controls are not aligning properly. Since HeaderColumn is null.

XYZ

ABC

DEF

CopyFrom

Could some one please suggest me to solve this issue.
I really apreciate it. Since I spent lot of time ont his but didn't get resolved.

Thanks in Advance

[Solved] FormDecorator on RadWindow with Content Template?

Hi Telerik,

I am trying to re-create a RadWindow using a Content Template -- Previously, I had it created using a Navigate Url. I am finding that the RadFormDecorator isn't wanting to apply properly in this scenario?

My code:

<telerik:RadFormDecorator ID="RadFormDecorator1" Runat="server" DecoratedControls="All" DecorationZoneID="UploadDashboardWindow" Skin="Web20" />

<telerik:RadWindowManager ID="RadWindowManager1" Runat="Server" Skin="Web20" Modal="True" KeepInScreenBounds="True" EnableShadow="True" Behaviors="Close, Move" VisibleStatusbar="False" ReloadOnShow="True" ShowContentDuringLoad="False" Behavior="Close, Move" Title="Confirm Action" IconUrl="~/Content/Dashboard/Icons/radwindow_confirmdelete.png">

<Windows>

<telerik:RadWindow ID="HistoricalLocalSettingsWindow" Runat="Server" NavigateUrl="~/Dashboard/Dialog/Windows/HistoricalLocalSettings.aspx" OnClientShow="OnLocalSettingsShow" OnClientClose="OnHistoricalLocalSettingsClose" OnClientAutoSizeEnd="OnClientAutoSizeEnd" IconUrl="~/Content/Dashboard/Icons/radwindow_settings.png" Title="Settings" Width="450px" AutoSize="True" AutoSizeBehaviors="Height" />

<telerik:RadWindow ID="DashboardGlobalSettingsWindow" Runat="Server" NavigateUrl="~/Dashboard/Dialog/Windows/DashboardGlobalSettings.aspx" OnClientShow="OnDashboardGlobalSettingsShow" OnClientClose="OnDashboardGlobalSettingsClose" IconUrl="~/Content/Dashboard/Icons/radwindow_settings.png" OnClientAutoSizeEnd="OnClientAutoSizeEnd" Title="Global Settings" MinHeight="337px" Height="337px" Width="450px" />

<telerik:RadWindow ID="CustomLocalSettingsWindow" Runat="Server" NavigateUrl="~/Dashboard/Dialog/Windows/CustomLocalSettings.aspx" OnClientShow="OnLocalSettingsShow" OnClientClose="OnCustomLocalSettingsClose" IconUrl="~/Content/Dashboard/Icons/radwindow_settings.png" OnClientAutoSizeEnd="OnClientAutoSizeEnd" Title="Settings" Width="450px" Height="215px" />

<telerik:RadWindow ID="ReportWindow" Runat="Server" Title="CableSolve Report Viewer" Width="600" Height="500" OnClientClose="OnReportWindowClose" />

<telerik:RadWindow ID="UploadDashboardWindow" Runat="Server" IconUrl="~/Content/Dashboard/Icons/drive-upload.png" OnClientClose="OnUploadDashboardClose" OnClientAutoSizeEnd="OnClientAutoSizeEnd" Title="Upload Dashboard" Height="150">

<ContentTemplate>

<fieldset id="Upload Dashboard">

<legend>Upload Dashboard</legend>

<telerik:RadUpload ID="RadUpload1" Runat="server" AllowedFileExtensions=".xml" Skin="Web20" MaxFileInputsCount="1" ControlObjectsVisibility="None" Height="40px" Width="230px" BorderWidth="0px" >

</telerik:RadUpload>

<div class="BottomButton">

<telerik:RadButton ID="RadButton1" Runat="server" Skin="Web20" Text="Upload"/>

</div>

</fieldset>

</ContentTemplate>

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

I know the Telerik guide says not to place RadWindows with ContentTemplate inside of the RadWindowManager, but I rather like keeping the things grouped "master page -> slave page"-esque. I haven't noted any troubles with this setup yet, but if I encounter them I will reconsider that implementation.

Nevertheless, the DecorationZoneID doesn't seem to be forcing the RadWindow to become decorated. When I do not use a DecorationZoneID other things go wrong on my page, however, so I am hoping to be able to use this to target the appropriate window. The thought is that I don't actually want to decorate my base page, just the pop-up window, but now the pop-up window is part of the base page.. so, yeah.

What am I doing wrong with my implementation? Thanks.

Sean

EDIT: It seems its something to do with the DecorationZone. If I remove that it decorates the control properly.
Moreover, if I wrap the RadWindowManager in a div with ID "RadWindowsWrapper", and then set the DecorationZoneID="RadWindowsWrapper" I get -some- of the styling, but not all? I see my fieldset gain rounded corners, but it did not color properly. It colors properly if I remove the DecorationZoneID.
