Call Select from outside

Hi,
I have a question regarding AsyncUploader. I use this control to upload multiple files(images) and everything is working perfect. But I have a great problem regarding the layout. What I need is a button to call the function that the button " Select " calls it. I mean a button called "Load Photos" for example, which once clicked to open the window "Open" where I can select the files I need. A js script is perfect, a code behind will do also.
Thank you in advance,
Moroianu George

BIG PROBLEM WITH v4.0.30319

All Telerik Devs,

I tried this on multiple rad controls... it appears when I add ClientIDMode="Static" on the RadScheduler, or RadMenu, or the RadButton the RadWindow Control will just not open, or when it does open it will not show the content w/in the content template.

Just an FYI

Opening a RadWindow breaks other controls' CSS

Hello,

I have a page with multiple RadTabs and clicking a button on one of them brings up a modal RadWindow. When the modal window is closed, the page does a postback and some of the data is refreshed. Afterwards, if you navigate to another tab, the CSS on the Telerik controls doesn't display properly

I've inspected it with Firebug, and some of the CSS files from WebResource.axd are missing after the windows was opened/closed (compare attached 0css.png to 2css.png). The content in the RadWindow doesn't have any special CSS, and is using the same Telerik theme as the rest of the application.

In our code, we don't make any changes to anything CSS during the process of opening/loading the RadWindow. When we do a hard refresh, the page will correct itself. When we do a refresh with re-sending the Post data, the CSS problems remain.

Included are several screenshots of the application before, during, and after the RadWindow is shown, with the list of CSS resources during each step. Do you know what could be causing this loss in CSS resources from a RadWindow being closed?

Accessing items in child grid

I am trying to edit a checkbox in a grid on a popup edit form and can not seem to get acces to the control I need. The basic layout is I have a page with a RadGrid. The grid has a popup edit form that has a few controls (labels and textboxes) and a new grid that is populated when you edit the parent grid. On editing the parent I get primay key from the ItemDatabound if the item is in edit mode and is a grid editform item. I then
run my query to populate the child grid with the selected details I desire.
I am trying to allow a user to check or uncheck a checkbox that I then use to update a value in the database. I can access the underlying object in the itemcommand on the update by getting a reference to the grid and they getting the EditItems to then iterate through each GridItem. I have AllowMultiEdit set on my child grid and on the child grid pre_render I set each row to edit mode.What I don't have though is the checkbox control. If I try and do a find control on the child grid in the Editform I get a null back.

Here is a snippet of how I am defining the checkbox on the child grid:

<EditFormSettings EditFormType="Template">

<PopUpSettings Width="800" Height="500" />

<FormTemplate>

...

<telerik:GridTemplateColumn UniqueName="chkResubmitted">

<HeaderTemplate>

<asp:CheckBox id="headerChkbox" OnCheckedChanged="ToggleSelectedState" AutoPostBack="True"

runat="server" Text=" resubmitted" ></asp:CheckBox>

</HeaderTemplate>

<EditItemTemplate>

<asp:CheckBox id="chkResubmittedEdit" runat="server" />

</EditItemTemplate>
