How to insert with modified primary key

Hi,

I have a combination key made up by 3 fields (lead_id,location_id,seq_id). I need to increment seq_id in my code-behind before inserting into the table while the first 2 keys stay the same. Similar to this post but I'm doing in-place editing:

http://www.telerik.com/forums/add-edit-with-user-defined-primary-key

I'm unsure if it's doable but I tried both in-place and GridTemplateColumn as suggested in the post, but couldn't get it to work. I received this error - "Exception has been thrown by the target of an invocation." after it leaves the InsertCommand event. Is there anything I'm missing to get the seq_id modify and insert to table? I did set ReadOnly="False".

Here's my ascx:

<telerik:RadGrid ID="RadGrid1" runat="server" MasterTableView-EditMode="InPlace" DataSourceID="ObjectDataSource1" OnInsertCommand="RadGrid1_InsertCommand"

{

// Get last item's

int count = RadGrid1.Items.Count;

GridDataItem item = RadGrid1.Items[count - 1] as GridDataItem;

// Get last item's provider name

string providerName = item["current_provider"].Text;

// Add 1 to last item's seq id

string strSeqid = item["seq_id"].Text;

int seqid = int.Parse(item["seq_id"].Text) + 1;

// item about to get inserted

GridDataInsertItem insertedItem = (GridDataInsertItem)e.Item;

// Get provider name of the item about to get inserted

TextBox providerNameTextBox = insertedItem["current_provider"].Controls[0] as TextBox;

string providerNameInserted = providerNameTextBox.Text;

// Modify the seq id

(insertedItem["seq_id"].Controls[0] as TextBox).Text = seqid.ToString().Trim();

}

Thank you in advance for your help.

Row selection question

I have a grid that's set up to enable client selection and multiple row selection and also has a ClientSelectColumn in it. I would like to enable some specific behavior:

If I click a client row, I would like it to simply add that row to the list of selected rows. Right now, the only way to do this is to use the checkbox in the ClientSelectColumn. The problem with this is that a checkbox is a small control, and if you miss your click and end up clicking outside of the checkbox, it clears all previously selected rows and only selects that one row.

I would also like the row click to toggle selection -- click once, it selects. Click again, it deselects. Right now, clicking a row will only select, and to deselect you have to use the checkbox, which can introduce the problem above.

I know it's possible to Ctrl-click to select and deselect, but this has a variety of unwanted effects in the browsers. Firefox adds a border to the table cell that was Ctrl-clicked, and IE selects all the text in that row.

Has anyone figured out a way to have a row select process that's like what I'm seeking?

RadComboBox with WebAPI service as DataSource

I've been looking through examples and forums and have not seen a clear example of how to bind a RadComboBox using a WebAPI service as the DataSource. It seems that this would be supported, but I'm not having any luck getting it to work. Thanks for any help you can provide!

AutoResizeHeight and Focus

When I use AutoResizeHeight in an Editor and the editor grows beyond screen size the Editor focus goes to top on first click in the Editors content.
On the second click the focus stays in the right place.

Is this a flaw?

Replacing data in the same RadGrid

Greetings

I'm currently working on a project with RadGrid.
The website has one page and a RadGrid without any user settings.

By clicking buttons I change the type of the grid, its columns and its data.

Only when I have a Grid with two levels (e.g. DetailView), it's Impossible to replace it with other data that also has two levels.

For example, let's define:
A - One Level Grid (e.g. NO DetailView)
B - Grid with two levels (mastertabalView+DetailView)

A --> B (e.g. replace grid's data that has one level with data of two levels)
RESULT: REPLACEMENT SUCCESS

B --> A
RESULT: REPLACEMENT SUCCESS

B --> B
RESULT: REPLACEMENT FAIL

B --> A --> B
RESULT: REPLACEMENT FAILS

ASPX:

<telerik:RadGrid ID="RadGrid1" Height="100%" runat="server" EnableHeaderContextMenu="true">

<ClientSettings>

<Scrolling AllowScroll="True"></Scrolling>

</ClientSettings>

</telerik:RadGrid>

JS error in IE 8

I'm using IE8, version of Telerik.Web.UI is 2010.2.836.35.
In our application when Editor is opened under specific conditions, I receive next javascript error:

Invalid argument.

Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a1f68db6e-ab92-4c56-8744-13e09bf43565%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2010.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3a86f56c91-febb-4172-ae71-6c2ba2372421%3a16e4e7cd%3a86526ba7%3a874f8ea2%3af7645509%3a24ee1bba%3adc7e0bd%3a1569bb5f%3a63b115ed%3a1c565fc%3a30f1f089%3a19620875%3a490a9d4e,

line 8464 character 1

In Chrome and Firefox I do not get this error.
Using IE debugger, I can see that error happens in next two lines:
http://clip2net.com/clip/m71805/1308143195-clip-49kb.png

Note, that function _fixIEHeight goes after height was assigned. So, if height was negative (as in my case), Invalid argument error is thrown, and I have no possibility to check what this height mean because js is obfuscated.
If we have this _fixIEHeight call before assigning the value, everything should be good, as function really fixes wrong values.

Now I can't give you easy scenario to reproduce, as RadEditor is highly tied with our application. Please reply if the information above makes any sense.
