Add additional values to batch edit new values

Is there a way to add additional key/values to the change data so that it will be available in the OldValues and NewValues Hashtables?

I have a grid of data that could be edited from different pages at the same time and I need to pass an additional key/value pair with the change data to track DB Concurrency issues.

// callback function
function cell_changed(sender, args) {
var row = args.get_row();
var field = args.get_columnUniqueName(); // column
var value = args.get_editorValue();

var timestamp = row.getAttribute("data-ts");

// how can I add an addition change to pass back with the newValues
cell.add_change("ts", timestamp);
}

// is this close?

var id = sender._masterCleintID;
var editor = sender.get_batchEditingManager();
var changes = editor._changes[id];
changes[{rowIndex}] = {
{field} = {
originalValue = {
"ts": timestamp
}
}
}

Does this only work on the client side

Is there any capabilities in this control to have the image saved on the server vs. having them saved/downloaded to the client's computer. I'm not seeing anything, but i just want to confirm.

I'd love to have a tool that lets me pass in a URL and create the image based on the rendered page and have that image saved on the server.

Thanks!

Where did the RadComboBox ClientState data go?

Apparently at some point in time, when you wanted to get the selected row data from a RadComboBox from a calling form you look to the Request.Form item with the _ClientState in it's key. For example If I had this on Form1:

<telerik:RadComboBox ID="cbTabDup" runat="server" Height="100px" Width="100px" Skin="Default"

AutoPostBack="true" DropDownWidth="300px" HighlightTemplatedItems="True" MarkFirstMatch="true"

ShowDropDownOnTextboxClick="true">

<ItemTemplate>

<table cellpadding="1" cellspacing="0" class="Main" width="250px">

<tr>

<td width="100px">

<%#DataBinder.Eval(Container.DataItem, "Code")%>

</td>

<td nowrap>

<%#DataBinder.Eval(Container.DataItem, "Description")%>

</td>

<td style="display: none;">

<%# DataBinder.Eval(Container.DataItem, "ID") %>

</td>

</tr>

</table>

</ItemTemplate>

<HeaderTemplate>

<table cellpadding="1" cellspacing="0" class="Main" width="250px">

<tr>

<td class="ComboHeader" width="100px">

Code

</td>

<td class="ComboHeader">

Description

</td>

</tr>

</table>

</HeaderTemplate>

</telerik:RadComboBox>

and submitted it to Form2 using:
Response.Redirect("Form2.aspx", True)

In Form2 I could do something like this and get the values:

For Each key In Request.Form.AllKeys

If InStr(key, "cbTabDup_ClientState") > 0 Then

Dim clsRad As New clsRadComboRequest

clsRad.RadClientState = Request(key).ToString

clsRad.SetValues()

sDupText = clsRad.RadText

sDupDescText = clsRad.RadDesc

iDupInd = clsRad.RadValue

Exit For

End If

Next

Except for some unknown reason now, the Request array key containing the "cbTabDup_ClientState" is EMPTY? Where'd it go?

How do I bind only one node?

How do I bind only one node to a datatable or dataset(or sqldatasource I would like to use cache so it does not load every call as well)

<telerik:RadNavigation ID="RadNavigation1" runat="server" CssClass="siteMainMenu">

<Nodes>

<telerik:NavigationNode ID="NavigationNode1" Text="Home" runat="server" NavigateUrl="/">

</telerik:NavigationNode>

<telerik:NavigationNode ID="NavigationNode2" Text="Products" runat="server">

</telerik:NavigationNode>

<telerik:NavigationNode ID="NavigationNode3" Text="Support" runat="server">

<Nodes>

<telerik:NavigationNode Text="Tutorials"></telerik:NavigationNode>

<telerik:NavigationNode Text="Samples"></telerik:NavigationNode>

</Nodes>

</telerik:NavigationNode>

</Nodes>

</telerik:RadNavigation>

I have a dynamic list of products that I want to display as a drop down under NavigationNode2 "Products".

I suspect I would do something on nodedatabound but not sure what?

Thanks, Marty

Custom tooltip content

Is there any way that we can customize the content of the tooltip functionality in the RadPivotGrid?

I essentially want to be able to customize the tooltip that appears on a row header using load-on-demand functionality to display some content that would not always be needed, and would otherwise slow down the pivot grid significantly if I always had it render with the control.

Parent data source

Hi,

I'd like to access the parent data source from a column template. Something like this:

<telerik:GridTemplateColumn DataField="Number" HeaderText="Number">

<ItemTemplate>

<%# ((MyCollection)Parent.DataSource).MyProperty %>

</ItemTemplate>

</telerik:GridTemplateColumn>

where MyCollection represents a class I use to populate RadGrid and MyProperty is a property of this class that I'd like to access.

Is it possible to accomplish that?

Thanks,
Leszek

Drag and Drop grid rows

Hello rich Telerik Community,

I am into a strange problem, and couldn't find any clue that what's wrong!!

I want to use the drag and drop functionality of rad grid which is very attractive and effective for the experience of my user. The drag and drop function is working for the first item in the grid, but it doesn't work for the following items.

I am getting the error in the console window of my chrome broswer

Uncaught TypeError: Cannot read property 'attributes' of null
b._saveCellAttributes
Telerik.Web.UI.GridTableView.get_dataItems
Telerik.Web.UI.GridSelection._selectRowInternal
Telerik.Web.UI.GridSelection._click
(anonymous function)
b

I noticed that this error pops up when I click on the row. I don't know what is this. I am afraid that I will not be able to isolate the code for this problem, so it would be nice if someone can share their experience if they had this same issue. Any general idea will help me, I can give it a try.

Thanks

Improving your Filtering for Built-in Checkbox sample

Hello I used your documentation sample to develop a tri-state checkbox filter for boolean fields.
The problem with your sample is that every time a boolean filter is applyed (or cleared) all the other filters are reset.
Is there any way to improve your sample, so that when I clear the boolean filter, it is only removed from the current ones, without clearing all?
