Best way to control Grid CRUD behavior

What is the best way to control a RadGrids CRUD behavior depending on the users Role? I already have a grid built with all of the updating and deleting functionality built in. Now I want to allow only certain users the ability to update and delete.

Custom Formatter Provider with a GridBoundColumn

I have a simple RadGrid control a web page connecting to a view via a data source. One of the fields requires a special formatting.

I was wondering is there a way to tell the GridBoundColumn to use a particular class when executing the DataFormatString property on the data at Binding Time.

For example, here is an example of data from the view
AccNumber (long), Name (string), OpenDate (datetime)
931367200, Bob Smith, 9-Sep-2010
911405190, Sue Smith, 8-Sep-2009
734412678, Tony Mendica, 3-Jan-2001

What I want the grid to display the fields is as follows:
931 367 200      Smith, Bob        9-Sep-2010
911 405 190      Smith, Sue        8-Sep-2009
734 412 678 L   Mendica, Tony 3-Jan-2001

The account for Tony is special as it has long standing customer privileges, so I would like to use a custom formatter class that implements the IFormatProvider interface.

I have considered using the ItemDataBound event and providing the customer format hook in there - however, i would prefer to avoid that if possible.

Thoughts?

RadGrid CheckBoxes in EditForm

hi all,

  I am using a Template Form to edit values from a RadGrid, When the grid is displayed the checkboxes appear to be properly bound, and are showing the correct "checked state", based on the value of 1 or 0 coming from the back-end.

  However, when I try to update from this edit form, I consistently get the error message "Cannot insert the value NULL into column DepositReceived ...."

   I can understand that on a new record ( INSERT ) that these values might be interpreted as NULL, however, as I've just returned the existing data, with valid checkbox values, I don't understand why they are still being seen as NULL ??? This is for all check boxes, including those which are "True" and checked ( please see attached image file )

   In the EditForm, I am binding as follows :

<asp:CheckBox ID="cbDepositReceived" runat="server" Checked='<%#Eval("DepositReceived") %>' />

In the Grid, I am binding as follows :

<telerik:GridCheckBoxColumn DataField="DepositReceived" DataType="System.Boolean"

HeaderText="DepositReceived" SortExpression="DepositReceived" UniqueName="DepositReceived"

Visible="False" DefaultInsertValue="False" ConvertEmptyStringToNull="False">

</telerik:GridCheckBoxColumn>

  Any suggestions are very welcome -- I really don't want to have to deal with code-behind and hopefully I've missed something simple.

  thanks in advance

Non-Negative Number Required

I was wondering if there was a work around or another way of handling the load on demand functionality for the combo box that does not result in the "Non-Negative Number Required" error when scroll down? Currently we are working on the ASP.Net AJAX Q3 2009 Net35 version, I dont believe there is a free upgrade to the latest version is there?

Update Label With Key Value From Grid Row Selection

I'm trying to make a label control update to display the key value for the users row selection in a Radgrid. For some reason I can't get this to work. Data is populated by way of some Linq to Entities code in a separate class. Can someone show me what I'm doing wrong?

RadComboBox.SelectedItem is null

We populated radComboBox in page_load method once it not from post back. When the user click a button and we will read selected item using following code

cmbCustAcctNo.SelectedItem.Text

However, we got object null reference because SelectedItem is null. We have verified EnableLoadOnDemand = false and AllowCustomText = false. Do we miss anything?

version: 2008.2.826.35

<telerik:RadComboBox ID="cmbCustAcctNo" Width="128px"

runat="server" Skin="Office2007" CausesValidation="false" AutoPostBack="true"

ToolTip="Select Account Number"

onselectedindexchanged="cmbCustAcctNo_SelectedIndexChanged">

</telerik:RadComboBox>

IList<prcWebAccountsForUserResult> listOfAcctNo = accountNumbers.ToList();

cmbCustAcctNo.DataSource = listOfAcctNo;

cmbCustAcctNo.DataTextField = "AccountNumber";

cmbCustAcctNo.DataValueField = "AccountNumber";

cmbCustAcctNo.DataBind();
