[Solved] Rating column doesn't export to CSV/Excel

Hi everyone,

We are using a grid column and it's displayed correctly in the grid.
We have implemented an export function (using RadGrid1.MasterTableView.ExportToCSV();).
The resulting file is a CSV or excel without any value under the rating column.

Are there any known issue with the export of a rating column?

Thank you

Regis

Viewstate - The state information is invalid

Hi All:

Like others, I am experiencing the following error in my orders selection grid.

The state information is invalid for this page and might be corrupted.

at System.Web.UI.HiddenFieldPageStatePersister.Load()

The grid allows filtering and contains 2 RadDatePickers. If I change a value in the picker and press enter, I get the above error. If I tab out of the field then no error.

I have tried EnableLinqExpressions="False", but no luck.

Rad Chart - Expand Chart Area remove Legend & Title

Hi Guys

I am using the Chart control to display some dashboard summary data. The page area I have is not that large, so I need to maximise its use!

Issue: I want to remove the title and legend and stretch out the chart size and utilise the title and legend area!

Now I have removed the Chart title (set visible to false) and tried a number of settings on the Legend - (set visible to false, changed the legend position etc), although when I remove the title and legend, the space on the top for the title and on the right side for the legend is not utilised for chart I am displaying. I have also tried increasing the width and height of the chart, but again this increases the total canvas size and we are still left with the blank space on the top and right. I either need to be able to reduce the size of the canvas the chart sits on, or increase the chart size utilising the blank space on the right and top of the chart.

Can this be done?

I have attached an image of my graph for reference, and coloured blue the area I need to utilise.

Adding a custom attribute to an HTML element

Is there a simple way to add a custom attribute to a selected HTML element?

For example, I want to add an ID attribute to H1 tag for use with an anchor link. I was using standard anchor tags, but the issue is that they are not visible in edit mode. It makes working with anchors for non-HTML savvy people very hard.

Any ideas would be greatly appreciated.

Getting Top/Left in OnClientDragEnd

Hi,

I'm looking into the OnClientDragEnd event of the radWindow control. I want to get the window to simulate a snap to grid. in the event, I've tried the using the following:

- sender.getWindowBounds().x
- sender.get_Left()

Both always return the position of the window before the drag. i've looked at the online demo, but it doesn't look at the co-ordinates. Is there another property I need to look at for the dropped left/top?

BTW: on the bottom of the screen for the demo, it mentions 2 parameters expected, but says "sender" is the tooltip, not RadWindow.

Regards

Bobby

Radgrid issue with the shift key in multiselection

I wanted to know if there is a solution to a radgrid issue with the shift key in multiselection. When i do a multiselection of rows with shift key pressed, the radgrid doesn't throw a postback when the shift key is released.

I was testing some alternatives with the onkeyup event over radgrid but doesnt work well with shift key (dont throw event until ctrl key is pressed) , instead the event it works better with the ctrl key.

However i would appreciate a better solution that doesn't imply handling the key events.

I been follow this issue in this threads

http://www.telerik.com/community/forums/aspnet/grid/how-to-capture-special-keys-ctrl-shift-click-in-server-side.aspx

http://www.telerik.com/community/forums/aspnet-ajax/grid/selection-with-shift-doesn-t-work-as-expected-strange-behaviour.aspx

Thanks in advance.

[Solved] set_currentItemIndex with Animation

Hi!

In this thread I read about the animation feature with the set_currentItemIndex()-Method

So I tried it. But it does not work for me. Here is what I've done to get it work:

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadRotator ID="RadRotator1" runat="server" DataSourceID="xmlDataSource1"

FrameDuration="360000000" Width="675" ItemWidth="675" Height="265" ScrollDirection="Up"

ItemHeight="265">

<ItemTemplate>

<div class="itemTemplate">

<img src="Images/<%# XPath("filename") %>" style="border: 0px;" alt="banner" />

</div>

</ItemTemplate>

</telerik:RadRotator>

<asp:XmlDataSource ID="xmlDataSource1" runat="server" DataFile="banners.xml"></asp:XmlDataSource>

<div class="nav">

<a href="#" onclick="javascript:setNewContent(0);">Banner 1</a>

<a href="#" onclick="javascript:setNewContent(1);">Banner 2</a>

<a href="#" onclick="javascript:setNewContent(2);">Banner 3</a>

<a href="#" onclick="javascript:setNewContent(3);">Banner 4</a>

<a href="#" onclick="javascript:setNewContent(4);">Banner 5</a>

</div>

here the js:
function setNewContent(selectedContentIndex) {
    // finding the radRotator
    var rotator = $find('<%= RadRotator1.ClientID %>');
 
    rotator.set_currentItemIndex(selectedRotatorItem, true);
}

But doesn't work. What I have to do? //EDIT: What does not work? -> The animation does not work... the banner changes but without animation

Also it would be nice if you could show me how to turn off auto-scrolling, cannot find anything how to do this.

Thanks in advance!

RadConfirm problem Firefox 5.0

I'm using RadConfirm on a linkbutton to confirm a delete action. Since firefox 5.0 the button doesnt seem to continue the delete event untill i click it a second time. So first it shows the confirm, if I click ok, it does nothing untill i the linkbutton again. On older versions of firefox (havent tested 4.0) , IE or safari no problem..

I'm using the 2010 Q3 release.

I took the telerik examples and changed the button in the example into a linkbutton and noticed that it also stopped working on firefox 5.0.
Is there a workaround for this problem?

Thanks
Jonathan
