Timeline View - Time Slot Frustrations

Hello,
I just downloaded the latest version of the Scheduler and am trying to make a year long calendar of people's schedule, pretty similar to a Gantt chart. My schedule is not granular enough to consider time, so I believe the Timeline view is the best fit. However, I am running into some very frustrating configuration with the Scheduler while trying to do this.

First, I thought it would be easy to simply pick a date range that I wanted to view...it's not. You have to pick a start date and calculate the "NumberOfSlots" and set the "SlotDuration" to 1 day. While this is not complicated, it certainly was not the experience I expected from a Schedule control, let alone a Telerik control, and it took playing around with it awhile to get it to do this.
On a side note, when I try to show 365 slots, 1 per day, I have been receiving a javascript, but that's a issue for another forum post.

Second, I have not found a way to display an entire year, with each time slot being 1 month. The closest I can come is to set the "NumberOfSlots" to 12 and the "SlotDuration" to 30...but this isn't at all accurate. Is there a way that I have not found to do this?

Any thoughts would be greatly appreciated,
Thanks,
-Aaron

ItemCommand event fires twice

I know I must be doing something wrong here, but cannot figure out what it is.

Scenario:

I've got an ajaxified radGrid. It has a link button within one of the columns. I've added a conditionalpostback for this link button so when it fires it does a regular postback. but when the link button is pressed, the ItemCommand event gets fired twice for some reason. on clicking the linkbutton, i'm showing/hiding panels. Also, the grid exists within a user control, if that would make any difference.

any help is appreciated.

Accessing Binary Content of Inserted or Updated Data in GridBinaryImageColumn

The subject says it all :) I have a GridBinaryImageColumn in a RadGrid as:

<telerik:GridBinaryImageColumn

DataAlternateTextField="Title"

DataField="BinaryContent"

HeaderText="Image"

ImageAlign="NotSet"

ImageHeight="120px"

ImageWidth="120px"

ResizeMode="Fit"

UniqueName="BinaryContent">

</telerik:GridBinaryImageColumn>

I'm using code-behind and Entity Framework and want to take the binary content of the selected file and set that to the appropriate entity property (which is of course byte[]).

How? All the samples I can find are declarative or not quite what I want. Here's an example of where I'd like to place such functionality:

protected void SetValues(GridCommandEventArgs e)

{

if (e == null)

{

return;

}

if (!(e.Item is GridEditableItem))

{

return;

}

var editedItem = e.Item as GridEditableItem;

var hashTable = new Hashtable();

e.Item.OwnerTableView.ExtractValuesFromItem(hashTable, editedItem);

// Simpler form of access naturally won't work.

if (hashTable.ContainsKey("BinaryContent"))

{

// I KNOW I can't access the content like this:

// this.EntityBinaryContent = hashTable["BinaryContent"] == null

// ? null

// : SomeUtility.ConvertToBytes(hashTable["BinaryContent"]);

// But at this stage, with what I have to work with (e) etc.

// How can I easily get hold of the upload bytes?

}

Edit: Should mention the intention is that the binary data goes into the database and the file is never saved to a file system. So, I can't work with an uploaded file as there won't be one.

Many thanks,
Richard

Menu Item On Click not firing

I have a rad menu with several items. The menu items lead to different places depending on a few things, so i'm trying to implement an OnClick handler in the code behind to redirect appropriately. I've tried all kinds of combinations and scoured the forums and nothing has worked so far.

My OnClick method is just a stub right now with a breakpoint so I can see when it gets called, only it isn't getting called, and I'm redirected to the default.aspx page.

Ths is within a user control, if that matters. Are you aware of anything that could cause this behavior?

protected void RadMenu_ItemClick(object sender, RadMenuEventArgs e)

{

int i = 0;

String s = e.Item.Value;

}
