Select Rows from RadFilter results (in RadGrid)

I need some help. I have a RadGrid with a RadFilter to generate mailing lists. Once I have filtered RadGrid, can I select the rows based on the filtered results?

From a mailing list perspective, I want to add each row from the filtered list to another mailing jobs table.   So I want to iterate through the filtered RadGrid to get only the rows from the filtered set.

Can someone give me guidance?    Thanks in advance.

Problems with your sample code

Hi

I am trying to leverage the c# code you have at the following url:

http://www.telerik.com/help/aspnet/grid/grdfilteringfordatetimecolumnwithdataformatstring.html

Whilst there are several syntax errors I have been able to overcome most of them,
but the following line has me stumped:

string currentPattern = (TextBox)filterItem(((Pair)e.CommandArgument).Second).Controls(0).Text;

I get an error which says.

'filterItem is a variable but it is used like a method'.

What is this line supposed to be?

In the process you might want to clean up the other syntax errors too.

TIA

Custom filter date

Hello,

I build a class with Telerik Advices to custom filter date.

My RadFilter bind a RadGrid.
I can save filters in a sqlDataBase.

When I choose a value in my custom combo filter date : no problem.
I save it : no problem
I load it the same day : no problem

But if I load it the next day or after : I must select the value, again.
It is very restriction for users which save their filters.

Internet Explorer Bug with bulleted lists

Hi there,

Our users have come across a bug that only seems to effect IE (IE7 8 and 9 tested).

If you type the following over 3 lines:

line 1
line 2
line 3

Select it, then set its font size to say, 12px. So far so good. Now, with it still selected, turn it into a bulleted list. All 3 lines are put under one bullet point, and the following markup is produced:

<ul>

li><span style="font-size: 12px;">line 1<br />



    line 2<br />



    line 3</

span></li>

</

ul>

Whereas, Firefox and Chrome both render:

<ul>

li><span style="font-size: 12px;">line 1</span></li

<li><span style="font-size: 12px;">line 2</span></li

<li><span style="font-size: 12px;">line 3</span></li

</ul>

IE does it properly if you do it the opposite way, first a bullet list, then the font size.

I have just upgraded to Q3 2010 and the problem still exists.

Sorry if this is in the wrong area.

Regards,

RSPCA Victoria

Problem with set_virtualItemCount for radGrid in radWindow with radWindowManager

I have a rather complex scenario.

I'm creating a set of coordinating User Controls that give me a tabbed interface where the tabs are Help, Search, Search Results, List, Edit, New, View, and some customizable functions. I'm turning these into a fully ajaxified interface controlled by instantiated JavaScript objects in an external JS file so that I can have multiple interfaces on the same page that use this interface. I have to say that this would be much, much more difficult without you guys at Telerik.

When I did this, I was able to instantiate a single interface on a page and it all worked perfectly. Very snappy response since it's all Ajaxified. So, for the next step, I took this interface and placed it in a RadWindow within a RadWindowManager so that I could utilize it in a desktop-like MDI interface like you have in the demos section. When I did this, things started to go funky. To start, I was getting postbacks on things like tab clicks, grid sorting and paging, and stuff like that. I also noticed that the counts in the RadGrid pager were messed up.

To address this, I'm taking a step at a time in order to focus on a single problem with minimal complexity.

I've been able to recreate a situation where I have a radGrid within a radWindow within a radWindowManager, and I'm ONLY calling set_virtualItemCount(5) in order to test updating the pager on the RadGrid. When I load this page, it shows 21 items in 2 pages. When I click the button to trigger the JavaScript, it remains at 21 items in 2 pages.

IF I REMOVE the RadWindowManager, and just have a standalone RadWindow, clicking the button changes the page count information to 5 items in 1 page. And, of course, if I take out the RadWindow as well, clicking the button changes the page count to 5 items in 1 page.

Can you figure out what's going on here?

Here's my code. It's all self-contained (no external JS file):

I'm hoping, of course, that this uncovers the root of all of my problems with this solution. I have to say that I don't have a 100% grasp on all of the details with the postbacks, but I clearly was able to reproduce this problem.

I've tested this in Firefox 4.01, IE 9 (using modes for IE 8 and IE 9), Chrome 12.0.742.91, and safari 5.0.5.

Thanks for your assistance.

RadWindow + RadDockZone + IE7: Overflow problem

Hello,

I'm having a problem with RadWindow and RadDockZone, when the contents of RadDockZone is larger than the size of the RadWindow, in Internet Explorer 7, the RadDockZone overflows the RadWindow, creates the scroll bar, but the content overflow the RadWindow.

In real case I have in the RadWindow, one RadDockZone with some fields, and another below, with a RadGrid. But did this example that simulates the same problem:

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

<telerik:RadScriptManager ID="telerik_ajax_manager" runat="server" OutputCompression="AutoDetect" />

Overflow test: RadWindow + dockZone

<telerik:RadWindow ID="rad_window" runat="server" Title="Overflow test: RadWindow + dockZone" Modal="true" Width="500px" Height="400px" Behaviors="Close"

VisibleStatusbar="false" VisibleOnPageLoad="true">

<ContentTemplate>

<telerik:RadDockZone ID="dock_zone_1" runat="server" BorderStyle="None" >

<telerik:RadDock ID="dock_1" runat="server" Title="Dock Zone 1" Resizable="false" EnableDrag="false" DefaultCommands="ExpandCollapse">

<ContentTemplate>

test <br />

</ContentTemplate>

</telerik:RadDock>

</telerik:RadDockZone>

<telerik:RadDockZone ID="dock_zone_2" runat="server" BorderStyle="None" >

<telerik:RadDock ID="dock_2" runat="server" Title="Dock Zone 2" Resizable="false" EnableDrag="false" DefaultCommands="ExpandCollapse">

<ContentTemplate>

test <br />

</ContentTemplate>

</telerik:RadDock>

</telerik:RadDockZone>

</ContentTemplate>

</telerik:RadWindow>

</asp:Content>

Tested in FF3, FF4, IE7, IE8, IE9 and chrome. And the problem only occurs in IE7. I tried some solutions with css, but could not resolve satisfactorily.

It would be a bug? or just something that I'm setting wrong?

Z-order problem with grid filter

Hi

I have a somewhat complicated problem with z-ordering some of my UI elements.

The Site Master part of my page contains a RadMenu control, this has a z-index of 7000.

Elsewhere in my my page I have a docling area with several panels.

Originally when I undocked one of the panels I saw some controls bleeding through, because of
their higher z-index. My Site Master RadMenu was one of the problem controls, but so were
the Date and Time picker icons in a gris filter I have in part of my page.

So I decided to detect the undocking of my panel and bump its z-index to 7001.

This solved my problem.

Until!!!!!

I was then asked to put a grid in the dock area with filtering on a GridBoundColumn.

This shows a filter control that extends a dropdown when clicked.

Well this dropdown has a z-index less than 7001 so it appears behind my undocked area.

I thought this would be as simple as writting some jQuery in the doc ready function to tweak
the z-index of the dropdown, but either my selector is wrong or something else is preventing
me from affecting the z-index of the div you generate.

Help greatly appreaciated.

Creating a dock with initial parent as RadDockLayout

Hi Telerik,

I noticed something weird going on with my code and I was wondering if there was a way to avoid this scenario.

When I create a RadDock I attach it to a RadDockZone via "RadDockZone.Controls.Add(dock)". This sets the RadDock's Parent to RadDockZone.

When I recreate a RadDock on Page_Init, I allowed the RadDockLayout to move the RadDock into place during RadDockLayout_LoadDockLayout. This sets the RadDock's parent to RadDockLayout.

Thus, this code is necessary and I would like to condense it into something more sensible:

//The dock's parent can change. When it is first created the dock's parent is the DockZone, but after

//recreation the dock's parent is RadDockLayout.

RadPane pane = null;

if (Parent.GetType() == typeof(CormantRadDockZone))

{

pane = Parent.Parent as RadPane;

}

else

{

RadDockLayout dockLayout = Parent as RadDockLayout;

RadDockZone zone = dockLayout.RegisteredZones.Where(registeredZone => registeredZone.ID == DockZoneID).FirstOrDefault();

pane = zone.Parent as RadPane;

}

try

{

Chart.Height = new Unit(pane.Height.Value - 42, UnitType.Pixel);

Chart.Width = new Unit(pane.Width.Value - 22, UnitType.Pixel);

}

catch (Exception ex)

{

Logger.ErrorFormat("Unable to adjust chart dimensions. Reason: {0}", ex.Message);

}

Is my problem clear? How can I avoid this?
