RadGrid : EditMode = InPlace : how to get values clients side

I have a radGrid that has about 5 columns. The RadGrid is setup to me in inplace edit mode when doing an insert. I have subscribed to the OnCommand client event to capture the insert client side before it is sent to the server. The event IS firing but I cannot figure out for the life of me of how to get the inplace data that the user is trying to insert.

Any help would be GREATLY appreciated.

Re-arrange Update/Cancel Buttons In Inline Edit Mode

Hi,

Was just wondering if there's a simple way of re-arranging the Update/Cancel buttons when in In-line Edit Mode?

I'm using two images for my update (check mark) and cancel (red x). Is there a way to place my Update Button on the far left side of the Grid, and have my Cancel Button on the far right side of the grid when in edit mode?

Best Regards,

Landon

Radgrid - Problem on Add New Record

I have a RadGrid setup so that double clicking a row opens a form under the row to allow editing. The form itself lives in a web user control.

On this form one of the fields is a CheckBox. It looks like this.

<td><asp:CheckBox ID="chkIsActive" runat="server" Checked='<%# DataBinder.Eval( Container, "DataItem.con_Is_Active") %>' /></td>

The code in the 'Checked=' bit sees that on edit the Checked property gets set to True or False. Perfect.

However, when I hit the Add New Record button, this line gets a problem.

Specified cast is not valid.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidCastException: Specified cast is not valid.

Source Error:

Line 24:          <tr>
Line 25:          <td align="right">Active:</td>
Line 26:          <td><asp:CheckBox ID="chkIsActive" runat="server" Checked='<%# DataBinder.Eval( Container, "DataItem.con_Is_Active") %>' /></td>
Line 27:          <td></td>
Line 28:         <td></td>

Source File: c:\Dev\RadGrid\RadGrid\Controls\ContactDetails.ascx Line: 26

It's pretty easy to understand why. DataItem.con_Is_Active has no value on an Add New Record insert.

My question is, were do I intercept this to prevent this error on Adding a new Record?

I've looked for but have been unable to find the InitInsertButtons click event if any such event exists..

I'm sure this is simple I just don't know where to put such a check. I suppose what I'd like to do is set the DataItem.con_Is_Active property some default value (like 'False') before the it gets to this point.

Initial Sizing

The splitter is similar to the webmail demo (fulscreen)

However when the page loads you can clearly see the splitter be small, then "POP" into fullscreen.

Is there any way around that?? at least somehow set a default height so the popping isn't so in your face.

[Solved] Get the row index via a treeListCommandEventArgs

Hi,

I was wondering how can I get the index of row in the UpdateCommand events of a TreeList. In a RadGrid, it would be like this :

Guid uniqueIdentifer= Guid.Parse((RadGrid1.Items[e.Item.ItemIndex] as GridDataItem)["UniqueIdentifier"].Text);

But if doesn't work with a treeList. In fact, the proprety e.Item.ItemIndex doesn't seem to exist. So, I look around to found something, but I had no luck. So, may someone tell me how to retrieve the index of the selected row via a updateCommand.

Thank you

How to set page orientaion for PDF and Word file when exporting? Is it possible to convert directly from ExcelML to PDF or Word?

I tried following to export to pdf in Landscape page orientation:

RadGridResult.ExportSettings.Pdf.PageHeight = Unit.Parse("215mm")

RadGridResult.ExportSettings.Pdf.PageWidth = Unit.Parse("260mm");

But it didn't work, and I have no idea on how to export to Word in Landscape orientation.
But I can do it with Excel just fine. Is there anyway to "convert" Excel to PDF or Word format on the fly?

THanks

LamK.
