[Solved] Getting values on insert command

Hi there,

I'm having trouble to get the insert values of my grid. My grid does on every postback a databind and it seems, that if that is done, the insert values are gone. If I don't databind on every postback, the grid doesn't show up (no columns, no rows).

My code to get the values is this:

Dim insertedItem As GridEditFormInsertItem = TryCast(e.Item, GridEditFormInsertItem)

Dim test As Object = TryCast(insertedItem.FormColumns(0).Controls(0).Controls(1).Controls(0), TextBox)

test.Text should contain the value, but it doesn't. Do you have any idea?

Thanks and regards,
Mark

Can't get RadWindow smaller than 150px.

Hi Telerik,

I can't get my RadWindow to size below 150px and I don't know why! It seems super trivial. I've applied the normal CSS fixes. There's no auto-height going on, and I've set dimensions for all my controls. What do you guys think?

Relevant Code:

html, form, body

{

padding: 0;

margin: 0;

width: 250px;

height: 100%;

font-size: 12px;

font-family: "segoe ui",arial,sans-serif;

}

.LabelEnabled

{

color: Black !important;

}

.LabelDisabled

{

color: Gray !important;

}

.riTextBox

{

color: Black !important;

}

.BottomButton

{

margin-left: 93px;

}

// When a dialog window appears on the page, it does not automatically

// dialog window may drop off the screen. This method keeps dialog windows shown.

function OnClientAutoSizeEnd(dialogWindow) {

dialogWindow.center();

}

The OnClientAutoSizeEnd event doesn't fire. It's just boilerplate code I've been attaching to all my windows and I show it to be unambiguous with the state of my window.

The only thing I can think of is that there's something weird going on with the Upload control? Its generated markup is more complex than expected.

Thanks

Sys.WebForms.PageRequestManagerParserErrorException on Telerik Q1 2008

Occasionally, I got the same message Sys.WebForms.PageRequestManagerParserErrorException:: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Details: Error Parsing near 'Telerik.Web.UI.2008.'. I thought it only happened on Telerik 2007 version. Are you sure it caused by my version is still a trial version one or something else ?

Input control disapears in a TabStrip + PageView

Hi,

on Sharepoint 2010 we create an ASPX Layout Page with multiple PageViews. The PageViews are dynamically added to TabStrip by code-behind. If we put the RadUpload in the PageView it doesn't shows the File-Input Control. After first click on "Upload"-Button the input is visible and can be used. I think the problem is related to the postback of TabStrip-Click ... but how to prevent/to require a full postback to the current PageView ...

Screenshot:

I have defined four slidingpanes in the slidingzone in the aspx file.
In the InitComplete event method I have added two new panes and removed one exisiting pane.
When I load the page, I get the error message.
When I only add panes all working fine without the error
Only when I have removed an existing pane the error occurs after page is loaded.

I'm using the the telerik version 2011.2.712.35

Any idea why the error occurs?

Best regards,
