[Solved] Delete LinkButton firing when Enabled = False

Im in version 2010.3.1215.35 using IE 8.

Even though I have disabled my Delete LinkButton in the ItemDataBound event, and it looks disabled, I am still able to click it, which prompts me with the delete comfirmation message. When I click to confirm, it deletes my record.

Here's my code behind where I disable the LinkButton

protected void RadGridWorkRequestAsset_ItemDataBound(object sender, GridItemEventArgs e)

{

//Other code here

if (e.Item is GridDataItem)

{

var editItem = ((GridDataItem)e.Item);

var deleteButton = (LinkButton)editItem["DeleteColumn"].Controls[0];

if (deleteButton != null)

{

deleteButton.Enabled = false;

}

//Other code here

}

Here's my LinkButton on the ASCX page:

<telerik:GridClientDeleteColumn ConfirmText="Delete this record?" ButtonType="LinkButton" UniqueName="DeleteColumn" ConfirmTitle="Delete" ConfirmDialogType="Classic" CommandName="Delete">

</telerik:GridClientDeleteColumn>

I will also create a ticket so I can send you a small sample project to duplicate the problem.
Just posting for the forum users.

See attached screen shot.

Changing column width not working

If I set the width of a column in the master table view (using HeaderStyle.Width) and then set the width again to something different, the width doesn't change and seems to get stuck at the first width that had been set. (this is using TableLayout=Fixed and UseStaticHeaders=true, and AutoGenerateColumns=true)

Is there any way to clear the columns completely in the master table view so they are recreated when autogenerating new columns?

RadEditor added to a Server Composite Control

I have successfully added a radeditor control inside a server compositecontrol:

protected override void CreateChildControls()

{

Controls.Clear();

_txtBox = new TextBox();

_txtBox.ID = "txtEdit";

_edrBox = new RadEditor();

_edrBox.ID = "edrEdit";

_txtBox.TextChanged += new EventHandler(txtBox_TextChanged);

_edrBox.ValueChanged += new EventHandler(edrBox_ValueChanged);

this.Controls.Add(_txtBox);

this.Controls.Add(_edrBox);

}

But the problem is, when the server control is placed inside a formview and that formview is ajaxified by a radgrid (ie, in a master/detail relationship, clicking a row on the radgrid should refresh the details inside a formview), an Ajax javascript error shows up that a null reference is detected at the time of sys.load????

Attached is the javascript code (from microsoft ajax) showing the error where variable a is NULL.

How to execute validation and updating of fields of the form before Ajax request (async postback)?

Before to begin Ajax request (async postback), I execute JavaScript function, which validate and correct values of the form (removes hyphens from telephone number). Call of alert() shows that value of a field has changed. However, to the server transferred not changed value of a field (old value - before correction).

Example: I typed '55-55-55' in field and clicked button. Value of a field changes on '555555', but to the server transferred old value (before correction) - '55-55-55'. I need to transfer the corrected value. How it to make?

RadGrid paging issue

I have a RadGrid that binds to a web service which pulls data from a SQL database. There is a Workflow that inserts records into the database which are displayed in the RadGrid, but I've noticed that when new records are inserted into the database from Workflow that the page index is reset to the first page. So, two questions: First, is this typical behavior for the RadGrid or did I do something on my own to cause this? Second, if this is typical behavior, is there anything I can do to maintain the page that I was on when the new record was inserted into the table?

Thx in advance!

Yahoo-style scrolling scroll bar dragging is ok, but scroll bar button click is not... (IE8)

Even in your second example of your demos page "Yahoo-style scrolling" i'm experiancing the problem : http://demos.telerik.com/aspnet-ajax/grid/examples/client/virtualscrollpaging/defaultcs.aspx

while scrolling the bar with dragging, updates the records well, update panel is also working fine. but if i scroll the grid by scroll button down to the end, the update panel just blinks and seems to lose it's visibility, the records get updated after a while. By the time the update panel is lost and the grid refreshes with the newer records, neither client nor server events can be fired...

Exactly the same problem i'm having here, using IE8. But in Chrome it works perfectly fine...

Any solutions to this???

Trial Version Menu

When I'm not in debug mode on my machine, I am not able to test the functionality of the menu control due to a javascript error (I've seen another post detailing this limitation). I need to be able to do this to ensure that this control works on a Blackberry browser before I'll be able to make a case for buying the control for my company. Is there any way around this problem?

Thank you.

DestroyOnClose still caches - with example!

Hi All,
DestroyOnClose seems to be one of those topics that reoccurs but never really gets resolved.
I am suffering from the continued caching problem regardless of the DestroyOnClose variable. The thing that has ended most other threads on this has been a Telerik support person being unable to replicate or asking for an example. So I have done one up. The simplest I can think of. Since I cannot attach the project here, please see the code below.
Using this example :

Start the solution using MainPage as the start page
Click on the Launch1 button
A modal popup window will appear, with the string "Launch1" on the second line - as expected.
Close the window.
Now click on the Launch2 button.
The modal reappears, bearing the same content - is should say "Launch2" in the text.

I am using 2010.3.1109.40 version of the Telerik.Web.UI.

Please help me out with this.
Thanks,
Steele.
