Image manager xhtml invalid attribute: longdesc=""

Hi,

When I use the Image Manager to insert an image into the contents of the RadEditor a link like <img alt="" src="" longdesc="" /> is inserted (when I switch from the design view to the html view).
This is not xhtml compliant.
It is unclear to me why the attribute longdesc="" is inserted instead of title="".

Please inform me how to change longdesc into title when inserting images.

Regards

Editor

buttons on selected treeview node

Hello,

I have seen the implemented solutioin for this here:

http://www.telerik.com/community/forums/aspnet/treeview/show-image-at-right-side-of-selected-node.aspx

however I have not been able to use this for multiple buttons to the right of the selected treeview node...

I have tried everything to get my code working, and am trying to copy how the radfilter creates the buttons in the rfTool div box...

right now i have the following as a nodetemplate:

<NodeTemplate>

<div>

<asp:Label style="display:inline;" />

<asp:Label style="display:inline;" /></div>

<div>

<a id="tnb1" class="tnTool" >firstButton</a>

<a id="tnb2" class="tnTool" >firstButton</a></div>

</NodeTemplate>

with the following css defined:

.tnTool

{

background-image: url('/Images/FileExplorerToolbarSprites.png');

visibility:hidden;

text-indent:-3333px;

text-decoration:none;

float:left;

white-space:nowrap;

width:0px;

height:0px;

}

.boolTreeHover .tnTool

{

display:inline;

visibility:visible !important;

width:18px;

height:18px;

}

#tnb1.tnTool:hover {background-position:0 -18px;}

#tnb2.tnTool:hover { background-position:0 -36px;}

the class "boolTreeHover " is applied to the "selectedCssClass" property of the node in the code-behind.

the attached image shows what is rendered...

for some reason i *cannot* get the two anchor tags to render inline with the other two labels...

if i put the whole template into one div box, it renders on the same line, but the float:left css renders the buttons BEFORE the labels, rather than after.

any help would be greatly appreciated... thanks!

IE compatibility tag for RadGrid doesn't work

Hello,

our RadGrids which are created dynamically in code on server side, were rendered properly in IE 8.

However, in IE 9, it is not he case.
headers and columns are mislined, and both columns and headers don't take 100% width of the screen.
They are squezeed to left and about 50% of the width.
Using

<

meta http-equiv="X-UA-Compatible" content="IE=8" />

doesn't help

For now, We would prefere to keep our site IE 8 compatible and force documents to IE8 mode
What prevents IE to use IE8 mode for RadGrid on our pages?

Version of telerik we use is 2010.1.415.35

Thanks,
Marijana

Set Grid Hierarchy Programmatically

Hi,
I have a requirement to build a RadGrid entirely programmatically that is capable of:
a) Filtering
b) Showing a detail table

In order to get filtering working I can't use simple databinding with a dataset so I've chosen to use an ObjectDataSource . The problem is that I can't seem to set the "SelectParameters" for the ObjectDataSource that populates the detail table (you seem to only be able to do this declaratively).

////Create ObjectDataSource for Detail table

myDataTable2 = new DataTableWrapper(sourceDataTable2);

t = myDataTable.GetType();

objDataSource = new ObjectDataSource();

objDataSource.ID = "myDataSource2";

objDataSource.TypeName = t.AssemblyQualifiedName;

objDataSource.SelectMethod = "GetDetailTable";

//objDataSource.SelectParameters <-- need to set this somehow but it is readonly!!!!

objDataSource.ObjectCreating += new ObjectDataSourceObjectEventHandler(objDataSource2_ObjectCreating);

this.Controls.Add(objDataSource);

If anyone can help me I'd appreciate it.

Thanks,

Nick

Event for Server-Side Select All?

I have a TreeList that allows multiple row selection (server-side) and has a TreeListSelectColumn. This configuration also creates a checkbox in the header that allows all rows to be selected/deselected. When an individual row is selected the expected ItemCommand event is triggered on the server-side. However, when the select-all checkbox in the header is checked and all rows are selected, the subsequent postback does not generate ItemCommand events. Is there a particular event for this select-all postback? Any recommendations for capturing these selection changes?

Grouping with Programmic Filtering

I've getting an error on the grouping of my grid. I get the "Column ? does not exist in table" however it's here. I have a form with several ways to filter the grid. I need to group the grid based on the first 4 columns.

RadGrid databinding question

Hi,

I have a page that has a normal asp button and a radgrid. My radgrid uses the NeedDataSource command which is used because my radgrid has paging. However, when my page loads, the needdatasource will trigger and bind my radgrid with data. Is there any way I can load my page and not have the grid bind anything until the user clicks the button thats on my page?

In other words when the page is loaded, the radgrid will be empty, and only have data when the user clicks the button. It works if I remove the needdatasource, but I need this because of my paging. Any advice?

Thanks!

color:red !important;

}

Protected Sub rtvNav_NodeDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles rtvNav.NodeDataBound

e.Node.Enabled = False

e.Node.DisabledCssClass = "Custom"

End Sub

but this did not override the color, i.e. the node is still gray. I found the following post http://www.telerik.com/community/forums/aspnet-ajax/treeview/disabled-node-font-color.aspx but it is almost two years old and not sure if it still applies. The solution is problematic for me as well. The solution says to define

.RadTreeView_Default .rtDisabled .rtIn

{

color: black !important;

}

Problems:
1. The user is allowed to select their own theme so I'd have to define this for all of Telerik's themes
2. I only want to apply this to a specific tree in my application and not all the trees in my application. There could be multiple trees on the same page, one with the new style, and multiple that should behave in the default way (i.e. disabled nodes grey).

What can I do to get disabled nodes to color differently in one situation and not the next?
