How to resize radcombobox in editform that was created automatically?

Hello, i have 2 questions and they are related:
1. If you have a column that is bound to another table, and you go to edit a record, is there a way to resize the radcombobox that is provided by default?
2. If replacing the default with edititemtemplate, what is the proper way to bind that radcombobox to the current record value? setting text property doesn't work because its bound to the datasource later and overwrites your selection.

Thanks,
Viktor.

Export to PDF issue for Radgrid with RadTabStrip

Hi,

I am using radgrid with nested detail view.

whenever user click the row, it shows detail info for particular row in the form of RadListViews.

The RadListViews are inside RadTabStrip, now when i try to Eport to PDF, it throughs exception

Telerik.Web.Apoc.ApocException: internal-destination or external-destination must be specified in basic-link

When i removed the RadTabStrip from NestedViewTemplate, i am able to export to PDF, do we need special setting if i am using RadTabStrip.

Note: telerik Version=2010.1.309.35

The code is as follows:

<asp:Label ID="Label1" runat="server" Style="display: none;" Text='<%#Eval("ID") %>'></asp:Label>

<asp:Panel ID="NestedViewPanel" runat="server" CssClass="viewWrap">

<telerik:RadTabStrip EnableViewState="true" runat="server" ID="TabStip1" MultiPageID="Multipage1" SelectedIndex="1">

<Tabs>

<telerik:RadTab runat="server" Text="Employee Detail" PageViewID="PageView3">

</telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage runat="server" ID="Multipage1" SelectedIndex="1" RenderSelectedPageOnly= "false">

<telerik:RadPageView runat="server" ID="PageView3">

<telerik:RadListView ID="RadListView2" runat="server" DataSourceID="ObjectDataSource1"

   ItemPlaceholderID="EmptyDataHolder">

Invalid postback or callback argument.

Hi,

I try to set up a RadGrid with a delete-icon to delete a record. When the delete-button in the GridButtonColumn is from type LinkButton it works fine. But when I change it to an ImageButton to show the delete-icon, I get the following error when deleting a record:

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

The error appears after the confirmationdialog. I tried the Classic confirmationdialog, but it didn't help.

Any ideas?

Make expand arrow persist on expanded

I'm hoping this is an easy fix and just something I've overlooked. I have a horizontal menu with vertical slides for children and RightExpand slides for grandchildren. The child nodes display an arrow if they have children when hovered. This works great. However, when the mouse is moved to the grandchildren, the arrow disappears. Is there any way to get it to stay there so long as that child is expanded? Again, I'm sure this is something I'm overlooking. Here's some code:

This is what I have pertaining to the arrow: I can include more code if needed. Thank you.

.RadMenu_NavBlue .rmGroup .rmLink:hover .rmExpandRight,

.RadMenu_NavBlue .rmGroup .rmFocused .rmExpandRight,

.RadMenu_NavBlue .rmGroup .rmExpanded .rmExpandRight,

.RadMenu_NavBlue .rmGroup .rmSelected .rmExpandRight

{

background:url(menu/bluearrow.gif) no-repeat right;

}

RadMakedTextBox (introduced as a update contorl) OnBlur event suddenly Fires After Click On it

hi my dear friends :

i am so mad about onfocus and onblur events in ajaxify mode...
i have this problem in radcomboboxes and RadInput.

i have a radmaskedtextbox and i introduced it as a update control of an another ajaxified controls(such as radajaxmanager(ajaxified) and A RadTextBox).
in onblur of that radmaskedtextbox i call radajaxmanager ajaxRequest ( i Ajaxified RadAjaxManager).
when i click on that RadMaskedTextBox OnBlur event suddenly Fires (without click on another area) And The Codes in AjaxRequest Execute. (control loses it's focus)
i should click on it 2 or 3 time more for inputing data Because of losing focus.
why RadMasked Text Box Acts Like this?
i Have the same issue about a RadTextBoxes...

it seems without ajaxify mode every thing is ok but in ajaxify mode (introduce as a update control) focus and blur problems appear.

how can i fix this problem?

i am using radajaxmanager ....

thanks in future advance
best regards

RADUpload POST locking up

I have a simple form that has the RADUpload and RADProgressbar on it. I have a save and cancel buttons (ASP:BUTTONS) and have registered thr respective Telerik controls in the web.config file (See Below) and when I press the Save (Submit) button, the page never returns. Eventually I will get an ajax time out error. The project is .NET 4.0 and I am using the Telerik controls v4.0.30319. Note, when I also press the cancel button, I still have a locked up page. I have tried many different combinations such as
* uploaded zero files
* 1 very small file and
* 1 very large file

Ive built my own image editor dialog which is opened via a contextmenu for all img elements. Is there a way to refresh the content area so the edited image is refreshed without doing a postback?
