Enhanced RadGrid Filtering

Hi,

I am trying to implement enhanced filtering as described on this page http://www.telerik.com/help/aspnet-ajax/grid-basic-filtering.html and in this video http://www.telerikwatch.com/2008/09/telerik-watch-minute-enhancing-radgrid.html.

The idea is to allow the user to enter filter expressions like >=27, *ed and <>100 then hit Enter to execute the filter. My problem is with numeric fields which don't allow non numeric characters to be entered in the filter text box so you can't enter <>= characters.

I am using version 2011.3.1115.35

I have created a very simple page that demonstrates the problem. (see below) The page has a grid that uses the Products table in the Northwind sql database as a datasource. Any advice would begreatly appreciated.

Thanks

Terry

Here is the code for an example page that demonstrates the problem:

//Disable filter menu from showing [BROWSER BUG FIX]

cancelFilterMenu = true;

if (tableView == null)

tableView = $find(gridId).get_masterTableView();

//Try to auto set the filter function

var filter = Telerik.Web.UI.GridFilterFunction.Contains; //Default

[Solved] Extreme CPU/Memory when in iframe

Hi,

We have discovered a really nasty thing with the RadListBox. In my sample below, the CPU will hit 100% and memory will go up to about 2GB (happens in both IE10 and Firefox, Chrome seems unaffected) for about 10 seconds. Will often crash the browser since we hit the 2GB limit if other tabs are open...

This only occurs when the listbox is located inside an iframe, in my example I did this using a RadWindow, but a normal IFrame would do the same...

Here is the main page:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="window.aspx.vb" Inherits="TestaTredjepartWeb.window" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="s" runat="server">

</asp:ScriptManager>

<div>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">

<Windows>

<telerik:RadWindow ID="RadWindow1" runat="server" VisibleOnPageLoad="true" AutoSize="true" NavigateUrl="listbox.aspx">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

</div>

</form>

</body>

</html>

And here is the content page:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="listbox.aspx.vb" Inherits="TestaTredjepartWeb.listbox" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="s" runat="server">

</asp:ScriptManager>

<div>

<asp:UpdatePanel ID="up" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<telerik:RadListBox ID="rlb" runat="server" Width="330px" AllowReorder="true" AutoPostBackOnReorder="true" EnableDragAndDrop="true">

<Items>

<telerik:RadListBoxItem Text="aaa" />

<telerik:RadListBoxItem Text="bbb" />

<telerik:RadListBoxItem Text="ccc" />

<telerik:RadListBoxItem Text="ddd" />

<telerik:RadListBoxItem Text="eee" />

<telerik:RadListBoxItem Text="fff" />

<telerik:RadListBoxItem Text="ggg" />

<telerik:RadListBoxItem Text="hhh" />

</Items>

</telerik:RadListBox>

</ContentTemplate>

</asp:UpdatePanel>

</div>

</form>

</body>

</html>

The listbox need to have autopostbackonreorder and be located in an updatepanel.
To get this behavior:
1. Move one item up or down by drag and drop.
2. Move the cursor outside the radwindow (the mousout of the window will trigger this behavior)

When profiling the script, it is the following function that is the problem:

RadListBox._onDocumentMouseOut

RadEditor w/ custom link manager not pasting html at correct position in IE7+.

We are using the RadEditor with the LinkManager.ascx dialog (v2012.3.1308.45). We had to extend the link manager to add additional attributes to the link. To do so, we modified the _insertClickHandler function in link manager to the following:

_insertClickHandler: function (e) {

var modifiedLink = this.getModifiedLink();
modifiedLink.setAttribute("LinkOptions", "2");

var args = new Telerik.Web.UI.EditorCommandEventArgs("LinkManager", null, modifiedLink);
//backwards compatibility
args.realLink = modifiedLink;
Telerik.Web.UI.Dialogs.CommonDialogScript.get_windowReference().close(args);

},

This worked fine in our previous version of controls (v2011.something). After upgrading this now returns a link without the added attribute at the beginning of the editor.

Expected results:

some text.....
< a href LinkOptions="2" / >
some text....

Actual results:
< a href / >
some text...
some text...

I also tried the following:

_insertClickHandler: function (e) {
var modifiedLink = this.getModifiedLink();
modifiedLink.setAttribute("LinkOptions", "2");

var args = new Telerik.Web.UI.EditorCommandEventArgs("LinkManager", null, modifiedLink);
//backwards compatibility
args.realLink = modifiedLink;

var editor = this._clientParameters.editor;
editor.pasteHtml(args.value.outerHTML);

Telerik.Web.UI.Dialogs.CommonDialogScript.get_windowReference().close();
},

Not handing in args to the close routine keeps the added attribute and paste position and works well in chrome, but not in IE. How can I return the link I want at the cursor position? This worked great in previous versions. I don't want Telerik assuming that 'LinkOptions' is an invalid element and stripping it before it gets to the editor.

Thanks

MDI Example question

Hi,

I am new to telerik and slowly working my way through the product so please excuse my ignorance.

I have looked at the Window MDI example which I think might be quite a nice way to present my Dashboards and BI Forms. Where I am a little confused is that in the menu item you place the URL in the value property as opposed to the navigate URL property. The challenge I have is that normally, if using a standard menu, I would put something like ~/Sales/DailySales.aspx in the navigate URL property but the same does not work for the Value property.

In all the examples I have seen the all call external URL's using a fully qualified URL. If I try and use ~/sales/DailySales.aspx it cannot find the page.

What am I doing wrong?

RadGrid Frozen Column Issue

I'm having an issue with frozen colums and the RadGrid. The problem exist with IE9 and Chrome. When the webpage completes rendering the Radgrid paints with all rows showing (in this case there are only four rows) then it collaspes to 2 rows showing with a vertical scroll bar.
After resizing the webpage manual (by one or two pixels) the Radgrid will repaint all four rows will show, the vertical scroll bar goes away, and the frozen colums work as expected. As a hack, I tried using the windows.onload event to resize the window and move the window to see if that would fix the issue--it does not. I also tried the onGridCreated function and it did not resolve the issue. Any ideas?

Thanks

Reduce Number of ScriptResource Files

Is there a way to reduce the number of ScriptResource.axd files that load when a page is requested? I routinely have upwards of 20 of these files load each request.

Get Row Index Value - Server Side

I am having some trouble figuring out how to get the row index value from the radgrid.

Using Microsoft Gridview I 've been able to accomplish the following:

Dim row As GridViewRow = DirectCast(btnDetails.NamingContainer, GridViewRow)

'Grab the LabAcc_PK and feed it to the Lab details datasource
' finally, rebind the detailview

DBConnect.Open()

cmd.Connection = DBConnect
cmd.CommandType = Data.CommandType.StoredProcedure

cmd.CommandText = "usp_GetLabAccountDetails"

'Add Parameters of SQL Procedure

cmd.Parameters.AddWithValue("LabAcc_PK", Convert.ToString(Gridview1.(row.RowIndex).Value))

How do I do the same thing but using the radgrid.

thanks -

How to disable right-click on links?

Hi,

I am using RadEditor with the InsertLink dialog, which opens a custom dialog.
when I select the link and right-click on it, I get a context menu and when I choose set link properties, I get an exception regarding the dialogs handler which is not registered in my web.config. I tried to add it, but I still get the exception.

Finally, I decided to disable the right-click on link items.
I tried your example:

  <telerik:EditorContextMenu TagName="A" Enabled="false">
      <telerik:EditorTool Name="SetLinkProperties" />
      <telerik:EditorTool Name="Unlink" />
    </telerik:EditorContextMenu>

but I get an exception regarding spell-check:

'..\App_Data\RadSpell\en-US.tdf' is missing. The spellchecking functionality of RadEditor requires a dictionary file named 'en-US.tdf' in the '..\App_Data\RadSpell\' folder. Please, ensure that all needed dictionary files from the original RadEditor distribution are present. See the help for more details Controls > RadEditor > Spellchecker

How can I cancel the option to right-click on a link? Why do I get spellchecker error?
or how can I show my dialog on "set link properties"?

do you have any idea?

Thanks for your help.
