Questions on UI for ASP.NET AJAX Forum

Hi,

I have a function that iterates through all the nodes and places the checked nodes into a list. The problem is that it will miss any child nodes of collapsed parents because the parents are created on the server side with Telerik.Web.UI.TreeNodeExpandMode.ServerSideCallBack.

I believe what is happening is that because these nodes are defined requiring a callback, that their children are not written out to the browser until that AJAX callback is fired. Because of this, they do not come up in the tree.get_allNodes call I use to iterate through all the nodes at the time I use it because the parent nodes in question have not been expanded (i.e., the child nodes in question have not been added to the document).

Forcing all the nodes to expand prior to checking for checked nodes works, but is unwieldy.

Does anyone have any suggestions or ideas about how I might work around this? I'm not that familiar with using this control, so I thought maybe a more experienced user might be able to guide me in the right direction.

Any help appreciated.

Thanks,
Ted

Is there a way to prevent collapsing?

One can set it to be expanded on load as well as to not collapse on blur, but is there a way to force it to always be expanded? Various events will still collapse it and make the app look clunky. :<

i would like to use it like a listbox but with the filtering of a combobox (letter decoration of matched strings, etc ). I currently do it with standard asp.net listbox control and textbox control but want the rich text, etc. :>

Thanks.

Hidding detail grid rows but allowing the footer sum row to show.

I have a master/detail RadGrid that is using the detail row footer to display a sum of the detail rows. What I need to do is to display only the detail row footer row values but hide all of the actual detail rows. How can I do this?

Thanks,

Steve Holdorf

NumericPages pager shows one page only

Hello!

I use a RadGrid that receives data from a webservice. The webservice returns items and count in "Count" property. But NumericPages pager shows only "1" in pager bar. I have a lot of items and pager should show several pages. NextPrevNumericAndAdvanced shows message "Displaying page 1 of 151, items 1 to 15 of 2261." in this case. It means that count is recieved correctly.

What's the reason of this NumericPages pager behaviour? How can I get it to work properly?

Thanks for your help!

PS: Telerik.Web.UI.dll version is 2008.3.1105.35.

Detect Ajax early

I've got a RadGrid in an UpdatePanel and I'm using a ScriptManager. What's the earliest point in the page life cycle that I can detect I'm in an Ajax call, for example when a user clicks the edit button in the RadGrid? Specifically, can I detect that the user has clicked the edit button (or any other Ajax action) at PreInit? If so, how?

Thanks,
Kevin

Selectable Content

Hi Folks,

Really looking forward to using the pivot grid, looks like a great feature.

One concern/idea I have from sampling the demo's is the inability to select content from a single column.

When using pivot table's in a spreadsheet program, it allows the dataset to be filtered and grouped by specific columns and rows, your pivot grids allow for this, but when trying to select the data from one column to extract or copy the Telerik PivotGrid does not allow for this, it selects data from other columns on lower rows.

Unsure how easy it would be to allow for the user to be able to scroll to select the data from one column, but if this was not possible then perhaps check boxes to allow for row and column select to enable some way to extract specific data?

I know the pivot grids are new, so thought I'd put in my two cents and hopefully see something along these lines be implemented in the future.

Regards
Ryan

Return bool value from Javascript

I am having a Grid view where I will have a column with Status Y/N. If the status is N I will show a Pop up saying do you want to approve, If ok was pressed I would like to return true from Javascript and need to update my table and allow user to edit the details if cancel I would like to return false from Javascript and make edit false.

This is my script

<script language="javascript" type="text/javascript">

function confirmCallBackFn(arg) {

if (arg == true) {

//should retun true

}

if (arg == false) {

//should retun false

}

</script>

In my ItemDatabound I will have some code that will check for N . If found I will show a pop up as follows

rdwndwPersonal.RadConfirm("Are you sure?", "confirmCallBackFn", 300, 100, null, "My Confirm");

From here I would like to return true/false from script so that if true I will update my table if not I will make edit to false.

TreeNodeExpandMode: b.toUpperCase is not a function

I am upgrading Telerik RadControls for ASP.Net Ajax from 2008.2.826 to 2009.2.701. For the most part things seem to be working well except for a few skinning issues and one very nagging JavaScript error.

The JavaScript error I need some help on produces the following:

b.toUpperCase is not a function.

Sys.__upperCaseTypes[b.toUpperCase()]=this; This is where it bombs (MicrosoftAjax.js)

Called by:

c.registerEnum(b,"TreeNodeExpandMode",{ClientSide:0,ServerSide:1,ServerSideCallBack:2,WebService:3}); (RadTreeViewSripts.js)

It seems like the object (b) being pass to the Sys.__upperCaseTypes does not implement the toUpperCase method.

Any help would be appreciated.

Thanks,

Andy Espinosa

How to retrieve updated data in RadGrid

Can someone show me how to retrieve data back from RadGrid row. This should not be a night-mare, but it turn out to be.

And looks like we have no support here from Telerik, after we bought the products.

Thanks.
