Feature Request

Hi,

before the DropdownTree comes up, we used RadComboBox with embedded RadTreeView in the ItemTemplate.
In the Databindings of the RadTreeView there where some nice settings like this:

<DataBindings>

<telerik:RadTreeNodeBinding CheckedField="isChecked" Expanded="True" CheckableField="isSelectable" />

</DataBindings>

Would be nice to have this settings in the DropdownTree too.

Kind Regards

Thomas

Index Outside Bounds of Array

The rows in my grid need to be updated with the value of a checkbox. The rad dropdown gets a value, then based off of that value, the checkbox gets an assigned value of 'active'(checked) or 'not active'(unchecked). When the user clicks on 'Save', each checked box will then take the ID and associate it to the ID of the dropdown list. Debugging stops at the GridCommandItem line and throws the error `Index was outside the bounds of the array.` Can someone please help me out here? I don't work with arrays much so I don't know how to fix this.

<telerik:RadDropDownList ID="MarketDropDownList" runat="server" DefaultMessage="--Select Market--" Width="200px" DataSourceID="ddlDataSource" DataTextField="MarketName" DataValueField="MarketID" AutoPostBack="true" OnSelectedIndexChanged="MarketDropDownList_SelectedIndexChanged">

PivotGridAggregateField with Calculated DataField

Hi:

I am trying to emulate a given Excel pivot table with the RadPivotGrid control. This pivot table has a calculated field used on the ‘∑ Values’ section with a ‘SUM’ aggregate function. I haven’t found a way to correctly set the PivotGridAggregateField tag. The formula for the calculated field is to divide other two fields, ex. field1/field2. What happens is that for each row Excel do: sum(field1) / sum(field2).

I am using ASP.NET 4.5, Windows 8, Internet Explorer 10.0.9200.16721, Telerik v.2013.2.717.45, C#.

The provided help will be appreciated.

Thanks!

Jose

e.Row.Cells.GetCellByName always returns null

Hello,

There is an issue with Radgrid excel exporting.

I have followed this example exactly http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/excelmlexport/defaultcs.aspx
except i make a call to the database on the code-behind rather than using a sqldatasource.

but on ExcelMLExportRowCreated i try to get a CellElement by cell name but it always comes back as null. i disabled autocreating columns because i create my own on the aspx page and i set a HeaderText, DataField, and UniqueName for each one. The datafield and UniqueName are the same and i use that when i call GetCellByName. Why is this not working?
What am i missing?

Please reply/fix asap.

Thanks.

How to use RadConfirm in a Similar way like Confirm

I have scenarios like :

function hello() {

if(confirm("hello"))

alert("yes");

else

alert("no");

}

I wanted to confirm this confirm to radconfirm. so I wrote a code like :

function hello(){

showconfirm();

if (test) {

alert("yes");//Here I might use some local variables

}

else

alert("Cancelled");//Here I might use some local variables

}

function showconfirm() {

radconfirm("Hello", confirmCallbackFunction);

}

function confirmCallbackFunction(arg) {

test = arg;

}

As radconfirm is non-blocking so an alert with "Cancelled" is always prompted without waiting for the value set from the radconfirm.. I can't do all the works in confirmCallbackFunction function because I will have some local variables in hello() function. In this case how can I use blocking radcofirm ?

I mean , I want to block the further code processing until a button is clicked from the confirm. I want the further codes to be processed after clicking one button in confirm. Thanks in advance for your help.

IE8 issue when inserting flash and media

When inserting flash or media in IE8, its adding two attributes (i.e. originalAttribute and originalPath) twice into the embed element, which is creating problem in rending the content. This error will occur when disabling EditorFilters.ConvertToXhtml filter. Is there any workaround for this problem?

FYI here is the generated markup:

<OBJECT classid=clsid:D27CDB6E-AE6D-11cf-96B8-444553540000 width=150 height=150>

<param name="Movie" value="/admin/static/qa3/usermedia/FrogLifeCycle.swf"/>
<param name="play" value="true"/>
<param name="quality" value="high"/>
<param name="wmode" value="transparent"/>
<param name="loop" value="false"/>
<param name="menu" value="false"/><embed src="/usermedia/FrogLifeCycle.swf" originalAttribute="src" originalPath="/usermedia/FrogLifeCycle.swf" originalAttribute="src" originalPath="/usermedia/FrogLifeCycle.swf" width="150" height="150" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" quality="high" wmode="transparent" loop="false" menu="false"></embed></OBJECT>

Excel-like filtering

Hello,

I saw that in Radcontrols for Winforms there is something called "Excel-like filtering". I really like it and I was wondering if it is possible to create filtering similar to "Excel-like filtering" in web application using existing components or maybe telerik is planning to create component like that.

Regards,
Kuba.

[Solved] Wrapping text in an Excel cell via GridExcelBuilder

When using the GridExcelBuilder to add and format a new row when exporting from the RadGrid, is there a way to set a cell within the row to wrap text? This would give the same effect as if you invoked the "Alignment > Text Control > Wrap Text" option in the Format Cells property sheet in Excel. Hopefully the code snippet below will give an idea of what I'm trying to do.

    
            protected void Grid_ExcelMLExportRowCreated ( object source, Telerik.Web.UI.GridExcelBuilder.GridExportExcelMLRowCreatedArgs e ) 
        
            { 
        
                if ( e.RowType == GridExportExcelMLRowType.HeaderRow ) 
        
                { 
        
                    RowElement myNewRow = new RowElement(); 
        
                    CellElement myNewCell = new CellElement(); 
        
                    myNewCell.StyleValue = "myNewStyle"; 
        
                    myNewCell.MergeAcross = e.Row.Cells.Count - 1; 
        
                    //now call the hypothetical property which doesn't seem to exist... 
        
                    myNewCell.WrapText = true; 
        
                    //etc... 
        
                } 
        
            }

Thanks,

[Solved] Comma is treated as letter.

Hallo Telerik Team

I am using two radtextboxes in my login.aspx with password strength checking enabled for the second textbox. I am following this http://www.telerik.com/help/aspnet-ajax/input-textbox-pasword-strength-checker.html tutorial. The issue is that if the user enter coma it is treated as a usual letter instead of a special character. Is this intended or some inadvertent pitfall in the control?
