Extending GridDataItem

Hello, I am migrating a control from GridView to RadGrid. With GridView, I was able to extend the GridViewRow class:

Public Class GridViewSearchRow

Inherits GridViewRow

ReadOnly Property SearchValueEntry As ISearchValueEntry

Get

Return FirstChildControl(Of ISearchValueEntry)()

End Get

End Property

Public Sub New(…)

MyBase.New(…)

End Sub

End Class

In its containing grid (an extension of GridView), I was able to instantiate my custom row by overriding GridView’s CreateRow function:

Protected Overrides Function CreateRow(…)As GridViewRow

If rowType = DataControlRowType.DataRow Then

Return New GridViewSearchRow(…)

Else

Return MyBase.CreateRow(…)

End If

End Function

In Telerik, I am able to extend the GridDataItem class:

Public Class RadSearchRow

Inherits GridDataItem

ReadOnly Property SearchValueEntry As ISearchValueEntry

Get

Return FirstChildControl(Of ISearchValueEntry)()

End Get

End Property

Public Sub New(…)

MyBase.New(…)

End Sub

End Class

Is there a similar way to ensure that all objects in the .Items() collection are added as RadSearchRow? I’ve noticed that the RadGrid’s GridDataItems are created within the CreateChildControl() sub, but since CreateChildControl() isn’t a function (like GridView’s CreateRow) I’m not sure how to mimic it.

Thank you very much.

LinkManager does not work as expected in IE8

Hello all,

I am using IE8.

I have the following lyperlink in the editor:

<a href="http://www.yahoo.com">http://www.yahoo.com</a>

I want to modify it using the LinkManager so the result will be as follows:

<a href="http://www.someotherwebsite.com">http://www.yahoo.com</a>

To do so, I selected the link and loaded the LinkManager. Then, I simply changed the URL to [http://www.someotherwebsite.com] and clicked OK (linkmanager1.jpg). Surprisingly, the markup still points to http://www.yahoo.com (linkmanager2.jpg).

This is working as I expect in IE7. Do you have any idea how can I fix this in IE8? I am using Telerik version 2009.3.1314.35.

Thanks,
Rez

Not working fine in firefox as Expected

Hi,

I am planing to use RadEditor control for my project use, So initially I am evaluating online Rad-editor app from here:

http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx

My basic requirement is make working app in all the browsers (IE, Firefox, Opera, Chrome, Safari) and dealing with adding custom controls to Editor, Image Manager, adding large range of tables, much more formatting, etc..

I found some of interesting thing while evaluating Rad-editor under FireFox v3.6.12 browser. Here are the few of issues I found in Firefox browser which are working great in IE8.

I can't able to delete the table using 'delete' key from keyboard, but I can delete by right-click on table->table delete
I am not able to set the absolute position to the Image/table/(any custom control) to change location of it.
When I move mouse over the Image, mouse pointer image is not changing in Firefox as like IE.
When I insert any Form Element in firefox, it is not selectable like in IE.

Please let me know about of your support on these issues once I use the Rad-editor?

Thanks,
Srinu Dhulipalla

Select a row using javascript

I am migrating an application from another company's control which selects an item in javascript under certain conditions. I can't seem to select a row.

    var grid = $find("<%=rgItems.ClientID%>").get_masterTableView();
    for(i=0;i<rowCount;i++) // rowCount set from hidden variable
{
   if (something is true)
   {
   grid.selectItem(i); // doesn't work
    }
}

Client-side data source manipulation

So I'm trying to accomplish something I'm finding a bit hard.

Grid on a page. I want to return to the grid a streamed set of records. JSON or XML or whatever. I need the grid to incorporate those records as they arrive on the client. Incorporating them will mean inserting them into the grid in the proper position based on some sort of sort criteria. Removing duplicates, expanding nodes, pushing results onto the next page.

Basically the server will take a long time to return all the results, and I want them to appear in the list as the server has them.

Doing this on the server isn't that hard. I already have the data being retrieved through a series of iterators just fine. Just trying to figure out the best way to deliver them client side.

Anybody have any examples of doing something like this?
