I am creating a grid at runtime with the code below. The issue is that the checkboxs in the checkbox column are disabled/readonly. I need these to be enabled so that users can check and uncheck them.

Here's my code:

Dim rgOnOrder As RadGrid = New RadGrid

rgOnOrder.AllowMultiRowEdit =

True

rgOnOrder.ID =

"rgOnOrder"

rgOnOrder.DataSourceID =

"WebOnOrderSource"

rgOnOrder.MasterTableView.DataKeyNames =

New String() {"VendorStyle"}

rgOnOrder.Skin =

"WebBlue"

rgOnOrder.Width = Unit.Percentage(98)

rgOnOrder.PageSize = 15

rgOnOrder.AllowPaging =

True

rgOnOrder.AllowSorting =

True

rgOnOrder.AllowFilteringByColumn =

False

rgOnOrder.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric

rgOnOrder.AutoGenerateColumns =

False

rgOnOrder.ExportSettings.IgnorePaging =

True

rgOnOrder.ExportSettings.OpenInNewWindow =

rgOnOrder.ExportSettings.Pdf.PageWidth = 11

rgOnOrder.ExportSettings.Pdf.PageHeight = 8.5

'Master table - Customers (I in hierarchy level)

Accessing other Columns values based on a TemplateCheckBox Column

Hi,

Unfortunatelly this is related to a previous post of mine but its a different issue I am having now, so I decided to create a new thread.

I have a Radgrid with 3 hierarchy Grids which is made completely in the Code Behind using C#. I have binded a RadtoolBar to the grid and created Column template based on a checkBox.

My application is suppossed to do the following:

1.Load a grid with new information from our new customers.
2.The hierarchy grids loads additional customer data, the products he has browsed, and the third hierarchy grid loads accounts from our database which share similar info with our new customer, so we can eventually disable these duplicate accounts.
3. The main grid and the third hierarchy grid have a checkbox column from a column template which on the customer side can be checked and disabled after the disable button from the radtoolbar has been pressed.

These two previous points I have been able to do.

Working on the third point has caused me alot of problems. In the checkbox template I was passing the customer id in the in the checkbox.id value, then via javascript I was navigating through all the checkbox inputs and determining which one was checked, then I would concatenate the customer ids into a hidden field, force a __doPostBack and disable the accounts, which worked great.

But this is my problem, when I expand the hierarchy grid with the duplicates, the names of the checkbox controls reset to a standard clientid and don't reload the id I had put in there before, so if I click a checkbox in the main grid the value is not passed, but in the hierarchy grid the value is passed, so it is one for another bassically...

One of the columns of the grid has the client Id, is it possible for me to determine which checkbox is checked from the grid and the hierarchy grid, then get the client Id, so I can disable the account?

Please let me know.
Thanks.

2009 Q2 installer doesn't install VS toolbox items

I've installed / uninstalled 2009 Q2 repeatedly.

Followed all the instructions in "Problems during install/uninstall" posting.

And I still cannot get it to install the toolbox items.

At least in the past there was an item in the Start Menu to register / re-register the toolbox items. Even that is missing now.

How can I get my toolbox items?

[Solved] Create Programmatically - SelectedIndexChanged EventHandler

I have an aspx page that contains a RadToolBar. In the RadToolBar, I create a RadComboBox at runtime. I've set the AutoPostBack = true and I've plumbed in the SelectedIndexChanged event handler. What I select a different item in the combo box, the page posts back but it does fire the event handler. I've also tried code to wire up the the javascript code to handle the OnClientSelectedIndexChanged client side event. That fires, but I'm not able to get any meaningful data our of the eventArgs. Any suggestions would be appreciate

CODE TO WIRE UP SERVER SIDE SelectedIndexChanged event

RadToolBarButton

button = new RadToolBarButton("some string");

this.radToolBarGrid.Items.Add(button);

//Create a RadComboBox to track the drill activity

RadComboBox radCombo = new RadComboBox();

radCombo.AutoPostBack =

true;

radCombo.SelectedIndexChanged +=

new RadComboBoxSelectedIndexChangedEventHandler(radCombo_SelectedIndexChanged);

radCombo.Items.Add(

new RadComboBoxItem(item.Value, item.Key));
....

this

.radToolBarGrid.DataBind();

void radCombo_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

throw new NotImplementedException();

}

CODE TO WIRE UP THE OnClientSelectedIndexChanged client side event.

radCombo.OnClientSelectedIndexChanged =

"HandleDrill";

function

HandleDrill(sender, eventArgs) {

var item = eventArgs.get_item();

// alert the new item text and value.

alert(item.Text +

":" + item.Value);

}

Scroll Issue

I have a simple horizontal image gallery using the rotator. One thing I've noticed though is that I can scroll up and down with my mouse and lose the images. It's easy for users to accidently do this and think something is wrong.

How can I disable the vertical scrolling so this doesn't happen? Thanks.

OnDemand 'Non-negative number required error'

Hi,

I have a on demand combobox dropdown configured to use a web service to be populated.

It works fine except in the following situation:
1 - I click on the dropdown
2 - I press the down arrow and it starts scrolling through the items
3 - When it gets to the end of the loaded items and tries to load more it pops up with the error mesage
"Non-negative number required. Parameter name: count"

This only happens when I use the down arrow to scroll through the items, if I click on the down arrow on the scroll bar then it works fine.

Any ideas how to fix this?

Cheers,
Liam.
