Drag and drop fires only once

Hi

I'm trying implement drag and drop functionality in my user control which is actually one of my custom wizard steps.
I've implement all most all parts of code in the online demo http://demos.telerik.com/aspnet-ajax/grid/examples/programming/draganddrop/defaultcs.aspx and faced with next situation : drag and drop fires only once. After this it doesn't work anymore unless I refresh page. Does anybody know how to fix it?

Thank you

How to Filter a Column without PostBack?

Hi everyone.

I'm new with Telerik Controls, and I have a question. I use DevExpress Controls a long time ago, and I remember that I can Filter the Columns data without PostBack, only tiping de text, and the grid Filter.

But, with the Telerik Grid... I can't do this... always fired a PostBack... and this is so slow...

Can I filter my Columns Data only by tiping the text I want to search???

Please help me...

Regards...

How to pass Form Template Edit Form textbox value to code behind

I have a RADGrid named 'RadGrid1' in my aspx page.

RadGrid1 has a form template edit form and this edit form contains:

A text box with an ID 'txtEmail' for editing the email address of the selected record
A button with an ID 'ButtonA'

What I am trying to do is:

When user click the 'ButtonA' button,
I want to send the email address information shown in the 'txtEmail' text box of the selected record to the code behind file's 'ButtonA' onClick event procedure.

I need to know the correct syntax/code for doing this.

Code behind file:

protected void ButtonA_Click(object sender, EventArgs e)

{

string EmailAddress = // How can I get the email address information shown in the ‘txtEmail’

// text box in the Form Template Edit Form

}

Thank you. :D

int itemOffset = context.NumberOfItems;

int endOffset = Math.Min(itemOffset + ItemsPerRequest, data.Rows.Count);

comboData.EndOfItems = endOffset == data.Rows.Count;

List<RadComboBoxItemData> result = new List<RadComboBoxItemData>(endOffset - itemOffset);

for (int i = itemOffset; i < endOffset; i++)

Hi, I've a boundcolumn named total and i want to filter that column having values range between x to y. 

i copied codes from demo in this link and modified for myself to decimal range.

thats my issue :

when i fill range textboxes (ex: ToValue=5 and Fromvalue=1) and press filter button

this.startValue

 has "1 5" and this.endValue has "5".



i changed the order of textboxes and realized that the first textbox always gets the both boxes value with a space between them.



Am i missing something or is this a bug??

Reverse(Crosspage postback)

I came across this article: http://www.telerik.com/help/aspnet-ajax/tabstrip-web-pages-cross-page-postback.html

Is there any so that I can have tab strip to get posted back (instead causing post-back) from (instead to) a different Web page from the one that contains it.
