z-index in 2013Q1

Have you changed the default z-index in 2013Q1?

I had a css overlay "eu cookie warning" which is now obscured by a radpanelbar since upgrading to 2013Q1.

I have fixed this by explicitly setting a very high z-index for the overlay, which is fine.

But can you confirm whether this is a bug, or do you have a new updated list of default z-indices for all controls.

[Solved] Save client side changes before/after NeedDataSource event?

I'm trying to have a radgrid that uses the needdatasource event to allow filtering/sorting, but how do I keep client side changes made to the grid in between loads?

For example, the page loads, then a user clicks a button which changes the selected row on the client side. The user then sorts/filters and the changes are gone. I would like those changes to be preserved. The changes are actually committed to the server on another button click. Is this possible?

How To: RadPanelBar Expand From Code Behind

Hi, I have a Panel Bar on a page that will display different errors for different reasons (from a query string).
I want to tell the Panel Bar (On Page Load - a protected void will be called) to Expand or Enable certain RadPanelItem(s).

Code Behind:

protected void LoadPanelItems()

{

RadPanelItem expired = rdPnlStatusError.FindItemByValue("ExpiredPassword");

RadPanelItem locked = rdPnlStatusError.FindItemByValue("AccountLocked");

RadPanelItem invalid = rdPnlStatusError.FindItemByValue("InvalidLogin");

RadPanelItem forgot = rdPnlStatusError.FindItemByValue("ForgotPassword");

var errCode = GetError(Request.QueryString["eCode"]);

switch (errCode)

{

case "ValidExpired":

expired.Expanded = true;

locked.Enabled = false;

invalid.Enabled = false;

forgot.Enabled = false;

break;

case "AccountLocked":

locked.Expanded = true;

expired.Enabled = false;

invalid.Enabled = false;

forgot.Enabled = false;

break;

case "Invalid":

invalid.Expanded = true;

locked.Enabled = false;

expired.Enabled = false;

forgot.Enabled = false;

break;

case "ForgotPassword":

forgot.Expanded=true;

invalid.Enabled = false;

locked.Enabled = false;

expired.Enabled = false;

break;

}

It doesn't work - is there any way I CAN get that to work?

Expandable controls cause scrollbars?

Hello,

I am not sure if this is a Window issue or a DropDownTree issue, so I am just putting this here.

I am using a Window as a modal popup set to AutoSize based on the initial content. Inside of this I have several controls, of them the DropDownTree. When the DropDownTree is expanded it causes the Window to force scrollbars to appear both Vertically and Horizontally. I am looking for one of two possible solutions to correct this so there are no scrollbars on the Window: 1) Allow the DropDownTree to expand outside of the Window instead of inside of it. 2) Have the DropDownTree shift when expanded so it operates more like the ComboBox where it is aware of the Window's frame and adjusts its height accordingly, and then places the scrollbar inside the tree instead of the Window.

Thanks for the help.

RadChart

Hello,

We are using Telerik.web.chart charts and then convert them to images using chart.Save()

I works fine when I use from web application, however if I invoke using windows service it throws an

"Object reference not set to an instance of an object." error.

Stack trace suggests at Telerik.Web.UI.RadChart.Save(Stream stream, ImageFormat imageFormat).

however radchart object itself is not null but scriptmanager property is

Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request

is there a way to generate images using telerik.web.UI outside http context or is it a completely different error.

cheers Vijay

Grid Losing Data in Multiview After When Any View Is Updated

Hello,

I have a strange problem with the behavior of radgrids that are located on different views within a multi-view after any any update is performed within any of the views themselves. After initially populating the the various grids within the different views, everything looks fine and switching between the views causes no issue. However, as soon as I do anything that initiates an update it causes all of the radgrids within the various views to lose most of their information and only display partial information of the first line. I have included screenshot below of what one of the grids looks like after initial databinding and then what it looks like after updating any of the views in the multiview.

I have tried hooking into the NeedDataSourceEvent, but that does not do anything to help the problem. Additionally, I also tried setting the RenderActiveView mode to both false and true and this did not solve any problems either. One other thing to note is that I don't even have to update data or controls within one of the views for this to happen. For instance, if I simply click a button that has code behind to change the view that is currently active, the same problem happens.

Following is the markup for the multiview:

Grid Javascript error trying to collapse group

var d=typeof(z)==="undefined"?false:true;
if(typeof(z)==="undefined"){z=l;
}if(!this._owner.ClientSettings.AllowGroupExpandCollapse){return;
}var x=l.id.split("__")[0]; <-- 4094

l.id is not defined at line 4094.

The page containing the datagrid with grouping is in an iframe.

l.name is the same of our web apps iframe, why should the javascript need to know the id of the page.

The javascript appears to be for the radgrid.

Any ideas...?

[Solved] Remove Check All Check is not working as expected...

PLEASE SEE ATTACHED IMAGE for screen captures...

I have a bit of code that is called to remove all checked items in various radcomboboxes with checkboxes...

My code works great to remove their selections, but if they use the check all option and then opt to clear all selections (a button event) all the checked items are unchecked EXCEPT for the check all...

function clearCheckedItems(combo) {

for (var i = 0; i < combo.get_items().get_count(); i++) {

combo.trackChanges();

combo.get_items().getItem(i).set_checked(false

);

		// The following code I was hoping to use to clear the checkall box...

//var element = combo.get_dropDownElement();

//var checkAll = $telerik.$(element).find(".rcbCheckAllItemsCheckBox");

// So what do I need to do at this point to clear the check all checkbox...??

combo.commitChanges();

}

FilterExpression Linq Syntax?

What exactly is the syntax for the FilterExpression? Sometimes it looks VB-like, other time C#-like. For example:

IsEmpty: (it["Member"] = "")
NotIsEmpty: (it["Member"] <> "")
IsNull: (it["Member"] == Convert.DBNull)
NotIsNull: ((it["Member"] != Convert.DBNull))

The first two linq expressions use = and <>, which is VB-like, but the second two use == and !=, which is C#-like!

Note: These were generated one after the other on the same grid with no other changes. Column type is GridBoundColumn (created in code-behind) with DataType = System.String.

ImageManager Broken After update to 2013.1.220.40

I have a Rad Editor with the ImageManager enabled. The image manager displayed correctly until up updated from 2012.2.912.40 to 2013.1.220.40.

It is almost as if the default skin is no longer being applied. I have not skin specified on the RadEditor or in the Web.config.

See attached images.

Again, this worked until I updated telerik. No other changes were made.
