ajax/javascript postback to codebehind from radlistview

Hi I have a radlistview that gets random items from the database, each item has two buttons inside add to wishlist, add to cart.
I wanna do a clientside event to a javascript that triggers an event in codebehind without
reloading the webpage. Each button has two arguments that needs to be posted
back to a code behind event.

I cant use ajaxpanel for the radlistview considering it's getting random items, it wont work because the id value of the index wont be the same after postback. didnt even work when I put the buttons directly inside a radajaxpanel.

What I would like to know what is the best way in with RadControls to do this with javascript AJAX event...

A working sample would be appreciated because I have searched all over the web and in teleriks vast resources but havent been
able to find something that works nor figure it out on my own. this will also trigger a external
ajaxpanel to reload and show the result of the button clicked but thats an easy fix when the rest is solved.

Thanks,

Ajax

Text Alignment

I have an odd question. I have a radgird that I allow edit and insert here is a sample of a column

<telerik:GridTemplateColumn HeaderText="Description" SortExpression="Description" UniqueName="Description" >

<ItemTemplate>

<asp:Label runat="server" ID="lbDescription" Text='<%# Eval("Description")%>'></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadTextBox ID="tbDescription" Width="300px" TextMode="MultiLine" Text='<%# Eval("Description")%>'

runat="server" />

</EditItemTemplate>

</telerik:GridTemplateColumn>

The problem is the label "Description:" is aligned vertical center on the RadTextBox. Is there a way to align it Vertical Top?

                foreach (GridDataItem dataItem in radGrid.MasterTableView.Items)
                {
                    (dataItem[columnName].Controls[0]).Visible = false;
                }
            }

Returning Values from a Dialog and doing something

I want to use a window as a means of collecting data, validating when the user presses OK then if all is OK, return to the parent form and save to the database.

Your "Returning Values from a Dialog " sample doesn't actually return to the code behind part, but updates the form using a java script.

I'm not very familiar with scripts and would prefer to do the work in the code behind part of the form.

How can I do this?

Thanks
Jeremy

Use of FindItemsByKeyValues troubles

Hi.

I'm using a RadGrid object and I want to find an item by its keys values.

The dictionary is a Hashtable that is filled with a foreach iteration.

Hashtable d = new Hasthable();

for (int i = 0; i < partK.Length; i++)

{

d.Add(partK[i], partV[i]);

}

GridDataItem[] gdis = listGrid.MasterTableView.FindItemsByKeyValues(d);

I'm using the following example. Dictionary d is filled with the following values:

-      d   Count = 2   System.Collections.Hashtable
+      ["MVFCodCIA"]   "035"
+      ["MVFRefXRisk"]   "70000598"

At the listGrid, if I make the following question at the inspection window I have this:

listGrid.Items[7].KeyValues   "{MVFCodCIA:\"035\",MVFRefXRisk:\"70000598\"}"   string

So the item exists.

When I debug the code, gdis.Length is 0, so the FindItemsByKeyValues doesn't find me the item I'm searching.

Am I doing something wrong?

Thanks.

OnKeyPress and caret position

Hello,

Is there a feasible way of determining what the new value will be of an input control inside of a OnKeyPress client-side handler?

- I've seen a lot of postings here showing sender.get_value() + args.get_keyCharacter() - but of course that assumes that the user is typing straight through and the cursor is at the end of the control. Not always the case! ;)
- The reason I'm looking to do this is to implement regex validation in real time (keydown or OnKeyPress), before the control loses focus. OnValueChanged and OnValueChanging occur on blur. (ASP.NET validation on post-back is clumsy and not appropriate for the circumstances we need this).

Ideally, though, Telerik could release a RegEx version of RadTextBox!

Thanks,

- Mike

Getting 'htmlfile:Unexpected call to method or property access' error

I am getting the 'htmlfile:Unexpected call to method or property access' error while I select a Treeview node and click on a button on the second attempt. i.e first I select a node and click on the button which opens a Radwindow pop up and then when I close the Radwindow , I make a Ajax request on the parent page to refrsh the Treeview control. Once that is done , when I select some other node and click on the button (to update the information opening a Radwindow) , I get the above error mentioned. I read in several of your threads that It is related to IE 8 and the latest version of RadControls for ASP.NET AJAX resolves this issue. But I have the latest 2011 1Q SP2 version, but still it's not resolved.

Thanks
Madhu
