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;

}

<radM:RadMenu ID="RadMenu" runat="server" OnItemClick="RadMenu_ItemClick" >

<Items>

<radM:RadMenuItem runat="server" ID="sampleItem" Text="Click Me" />

</Items>

</radM:RadMenu>

RadGrid 508 Accessibility.

I have a RadGrid. I want to make it UI accessible. In this grid I am using checkboxes for row selection like this:

<telerik:GridClientSelectColumn UniqueName="headerSelectAll" ItemStyle-Width="40px"
ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="40px" HeaderStyle-HorizontalAlign="Center" />

Each checkbox is clickable and I want that it will be 508 UI Accessible. Please suggest for it.

Thanks.
