Trying to get a value from a linkbutton...

Hello,

In my codebehind I am creating a Radgrid and adding the columns to the grid. One of those columns is a GridButtonColumn. The code looks like so...

    
                                Dim clmbtnGRDMAIN1 As New Telerik.Web.UI.GridButtonColumn  
        
                                clmbtnGRDMAIN1.DataTextField = rowCOLUMN.FIELDNAME  
        
                                clmbtnGRDMAIN1.HeaderText = rowCOLUMN.EXTERNAL_READABLE1  
        
                                clmbtnGRDMAIN1.UniqueName = rowCOLUMN.FIELDNAME  
        
                                clmbtnGRDMAIN1.HeaderStyle.Width = rowCOLUMN.GRIDWIDTH  
        
                                clmbtnGRDMAIN1.CommandName = "TEMPID" 
        
                                grdMAIN1.Columns.Add(clmbtnGRDMAIN1)

This works fine, it creates the button with the proper information. But what I want to do, is that after a user clicks on the link button, gather the value.

The Telerik example says to put some code in the ItemCreated event. Such as this...

    
                    If e.Item.ItemType = Telerik.Web.UI.GridItemType.Item Then 
        
                        Dim item As Telerik.Web.UI.GridDataItem  
        
                        item = e.Item  
        
                        Dim LinkButton1 As LinkButton  
        
                        LinkButton1 = item("TEMPID").Controls.Item(0)  
        
                        LinkButton1.CommandArgument = e.Item.ItemIndex.ToString()  
        
                    End If

This works and the index is correct.

But, when I try to get the value in the ItemCommand event, I get nothing. The code is here...

    
                        Dim index As Integer = Convert.ToInt32(e.CommandArgument)  
        
                        Dim item As Telerik.Web.UI.GridDataItem = grdMAIN1.Items(index)

And if I then do a Response.Write(item("TEMPID").Text, -1) it comes up with a space when it should contain a string of numbers.

Anyone have any idea what I'm doing wrong or how I can get this value properly? I'm having a heck of a time trying to do this. I feel as though it should be easier to get a value out of a link.

Thanks
Kevin

AJAX in Master Page?

I've added a simple combobox in a MasterPage that has a AJAX Web Form inside. The error I'm getting is:

'~/Telerik.Web.UI.WebResource.axd' is missing in web.config. RadScriptManager requires a HttpHandler registration in web.config. Please, use the control Smart Tag to add the handler automatically, or see the help for more information: Controls > RadScriptManager

I've added an httpHandler in my web.config under system.web settings (Windows 2003 server). Ideally this will be moved to the machine.config once I see it working.

What else can I check?

Filering Problem in Chrome (Dev Channel)

Hi,

we are testing our application with the latest Dev version of chrome (not released yet).
It seems like filtering the grid columns doesn't work with standard text based filters.
The item command event never gets fired and the value is lost on the next rebind.
Filtering columns where we have dropdown boxes as filter option still works as expected.
Also reordering columns via drag and drop doesn't work.

Could you comment on whether this is a chrome issue or a problem with the rad control?

Cheers,
Michael
P.S. tested this with Q3/2008 and Q1/2009

RadMenuItem in CommandItemTemplate - trying to use the commandName scenerio to call itemCommand()

Hi,
     I am trying to use a radmenu in a grid.
     I would like to use the menuitem to select Insert (add a new record, rather than a linkbutton). I am wondering how to get the commandName scenerio to work here so I can use the ItemCommand() method ?
     I have been searching for a sample of how to even use the itemClicked event to call the itemCommand() method.
thanks for your time.

Set focus on page load

I need to set the focus (selected menu item) on page load and can't figure out how to do it correctly. In code behind I tried

this.RadMenu1.Items[0].CssClass = "rmFocused";

and that works but it never loses focus no matter which menu items are clicked. I can't figure out how to make it lose focus when another menu item is clicked. I tried a client side event to set the CssClass and it does not work, nor does item.focus() - can't get any client side event to make it focused on loading. Seems a very simple task I want to do - just focus the darn item onload and take focus off when another item selected - simple eh? lol

[Solved] Is it possible to Serialize a DateTimeCollection?

I'm storing selected dates as a DatetimeCollection in a custom object.
I want to be able to store that object in viewstate, but I've been gettting the Serialization error

"Telerik.Web.UI.Calendar.Collections.DateTimeCollection is not marked as serializable"

i've already marked the class itself as Serializable, is there any way to serialize this?
or should I store the selected dates as an array or some other format?

Thank you
Deb
