How to completely reset the AsyncUpload control

Hello

I would like to know how to reset the control completely.

My upload control is in a popup (a simple absolute div) and has its own "Close" button. When the popup is closed, I want the Telerik control to completely reset, whether or not it is currently uploading or what state it is ...

I have tried using:
- deleteFileInputAt(0);
- _uploading = 0; i'm pretty sure this is not the way to go...
- _cancelUpload: this crashes a lot ... (stackoverflows etc....)

I'm searching for a reliable method to re-initialize the control like when the page was loaded.

Thanks !

ASP.NET RadWindow Maximize and Restore Animations

Hi,

I can set the "window close" animations for the RadWindow control. How do I set animations for Window Maximize (which puts the window to full-screen), and Window Restore (which puts the window back to partial screen)?

Thanks!

[Solved] Calculate Total of RadGrid based on two columns (Qty * Price) - Clientside

Here is the scenario:

I have a RadGrid with 3 columns -- Qty -- Description -- Price Per
Data comes in from the server - as a list of items you can select
The Qty column is a RadNumbericTextbox with spinner buttons -- Price Per is set from the database
When you change the Qty, I want to recalculate the total of all lines for the entire grid and show it in a separate RadNumbericTextbox outside of the RadGrid
The math is the sum of Qty * Price Per for all lines.

Attached screenshot shows the grid I am dealing with to give a clear idea...

Is there a good tutorial or documentation that explains this control and how it works. We just purchased the controls at my work and i'm trying to learn as much about them as possible. I'm not sure what this control does and how exactly to use it. Any help would be appreciated.

Thank you

Why does scrollIntoView() scroll when it doesn't need to?

The behavior I'm seeing is that scrollIntoView() modifies the position of the scrollbar even when the node in question is already in view. Is there a way to prevent this? In attempting to accomplish this, I haven't been able to find a property on the node that describes whether it is already in view. Can anyone help?

RadGrid reducing filter options

Hi

I'm using a Radgrid, fairly simple implementation:

<telerik:RadGrid ID="approval" runat="server" AutoGenerateColumns="False"

CellSpacing="0" GridLines="None" AllowFilteringByColumn="true"

onneeddatasource="approval_NeedDataSource"

OnItemCommand="approval_ItemCommand" OnInit="approval_Init" >

<MasterTableView allowpaging="True" datakeynames="Id" AllowSorting="true"

name="claims" commanditemdisplay="Bottom" AllowFilteringByColumn="true">

I'm having an issue with the filter options, I have enabled column filtering and this is working fine. I want to limit the number of filter options available. I followed this guide: http://www.telerik.com/help/aspnet-ajax/grid-reducing-filtermenu-options.html

I created an Init handler:

protected void approval_Init(object sender, EventArgs e)

{

GridFilterMenu menu = approval.FilterMenu;

int i = 0;

while (i < menu.Items.Count)

{

if (menu.Items[i].Text == "NoFilter" || menu.Items[i].Text == "Contains" || menu.Items[i].Text == "DoesNotContain"  || menu.Items[i].Text == "EqualTo" || menu.Items[i].Text == "GreaterThan" || menu.Items[i].Text == "LessThan")

{

i++;

}

else

{

menu.Items.RemoveAt(i);

}

However this isn't working, if I attach a breakpoint the code isn't being hit.

Any advice?

Thanks
