"Cannot set property 'control' of undefined" error when using CommandItemTemplate

I have a radgrid and since I have custom buttons, I am using the CommandItemTemplate. But it throws "Cannot set property 'control' of undefined" error! When I comment out this._RadGrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.Top; It does not throw the error and ofcourse the CommandItemTemplate is also not visible.

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

this._RadLoadingPanel.ID = "_RadLoadingPanel";

this._RadLoadingPanel.Transparency = 30;

[Solved] how to add column which is updated using code and can be sortable

How do I add column which is updated using code and can be sortable?
I have RadGrid, which get the data using Entities Framework query.
I added label (lblTest1) to get additional information which isn't returned by the query, but in this way the column isn't sortable (because it's not one of the query outcomes).
Is there a different way to update the column so it will be sortable using the field data or is there a way to sort according to this label?

aspx:

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" CellSpacing="0"

    var item = (Item)e.Item.DataItem;

    MoreInfoRepository moreInfoRepository = new MoreInfoRepository();

GridCalculatedColumn and EnableLinqExpressions=False cause Exception

Hi,

we have encountered a problem with the GridCalculatedColumn and EnableLinqExpressions = false where we receive an Exception on every PageLoad

Minimal Test Case:

<telerik:RadGrid ID="RadGrid1" DataSourceID="XmlDataSource1" runat="server" Width="990px"

EnableLinqExpressions="False">

<MasterTableView AutoGenerateColumns="False">

<Columns>

<telerik:GridBoundColumn runat="server" UniqueName="value1" DataField="value1" HeaderText="Value 1" />

<telerik:GridBoundColumn runat="server" UniqueName="value1" DataField="value1" HeaderText="Value 2" />

<telerik:GridCalculatedColumn runat="server" Expression="value1 + value2" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

<asp:xmldatasource id="XmlDataSource1" runat="server" datafile="Source.xml" xpath="DataPoints/Point"/>

source.xml

<?xml version="1.0" encoding="utf-8" ?>

<DataPoints>

<Point Value1="1" Value2="2"/>

</DataPoints>

This yields the Exception:

Replacing custom paragraph styles with the default ones does not work

Hi Guys,

I am experiencing the following problem:
I created my custom paragraph style "Small" for the FormatBlock Dropdown. It wraps text in <smal> tag and works as as expected.
However after applying this paragraph style it is not replaced with the <h1> etc. default styles when I choose them in the dropdown.
Steps to reproduce:
1. Put any text to the editor. For example: Test
2. Select it and click on the custom "Small" style in the FormatBlock Dropdown.
Result in the HTML view: <small>Test</small>.
3. Select the word again and click Heading 1 default style.
Result in the HTML view: <h1><small>Test</small></h1>.

On the other hand when I choose Heading 1, Heading 2, Menu etc. default styles successively, the current value replaces the old one:
<h1>Test</h1> => <h2>Test</h2> => <menu>Test</menu> => ...

Is this an expected behavior with the custom paragraph style or not?
Can you offer how to fix this issue in some simple way?

Best Regards,
Yuriy

RadFilter doesn't work with Arabic or persian context

Hi,
I'm using telerik RadFilter with RadFilterSqlQueryProvider but unfortunately I couldn't filter my datasource with persian or arabic contexts.
as I checked the generated result by RadFilterSqlQueryProvider it misses N keyword for Navarchar fields for example when we are filterring a nvarchar field we should write TSQL such this : select * from x where Name Like N'%رضا%' but the filter control just gives select * from x where Name Like '%رضا%' which can only work on varchar fields not Nvarchars.
I set the culture to both arabic and persian cultures but nothing happened.
Any help to solve this issue will be appreciated .

RadGrid NeedsDataSource, IQueryable<> and disposing of datacontext

I have a radgrid that calls NeedsDataSource.
I have a method like this:

protected void RadGridParentComponents_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

var result = new Inventory().GetComponets(this.HiddenFieldTag.Value);

RadGridParentComponents.DataSource = result;

}

Which in turn calls this bll bit of code... GetComponents

public IQueryable<TagInformationComponentView> GetComponets(string tag)

{

using (var dbContext = new TIPWebITLibrary.DAL.TIPWebITDataContext())

{

if (String.IsNullOrEmpty(tag)) { throw new ArgumentNullException("tag", "Null or Empty is not allowed"); }

var parent = dbContext.tblTechInventories.Where(x => x.Tag == tag).FirstOrDefault();

//TODO: Check to ensure it is a parent

var result = from c in dbContext.tblTechInventories

join p in dbContext.tblTechItems on c.ItemUID equals p.ItemUID

join t in dbContext.tblTechItemTypes on p.ItemTypeUID equals t.ItemTypeUID

where c.ParentInventoryUID == parent.InventoryUID

select new TagInformationComponentView()

{

InventoryUID = c.InventoryUID,

ProductName = p.ItemName,

ProductType = t.ItemTypeName,

Serial = c.Serial,

Tag = c.Tag

};

if (result.Count() == 0)

return new List<TagInformationComponentView>().AsQueryable();

return result.AsQueryable();

}

Now the question:

I know I can't wrap this in a USING because the context will be disposed and the RadGrid does not like this...
How do I dispose of the context when I am done with it correctly?
I have used .toList() in the past but from what i have read this method does not leverage the full power of the radgrids queryable functionality.. Am i wrong in this or what?
