I have searched around for a while but have not found any code in the demos or forum on how to make the update button in an edit form on radgrid onclick run some client side error checking (code for accessing the ids of the text boxes a plus) and then if it passes move on to the RadGrid1_UpdateCommand.

Thanks for your help

Rad Grid's Filter Options(Like Equal to..) Display below MenuBar

Hi,
I went through one issue.Problem is that I have RadGrid in a page whose Property AllowFilteringByColumn is set to true.
And there is one RadMenu on top of Page..So When My data is displayed in RadGrid and when I click
on column for filtering values then I get many Context Menu options Like(Greater Than,Smaller Than,Equal To.....),
these are the options on which based I want to filter my data.
But Problem is that those Context Menu options's height is more So those come below to Menu Bar.Is there any way so that
those options will come above of Menu Bar.I tried ZIndex in RadGrid but It does not work.
I hope I'll get my solution soon.

Thanks

Fixed number of lines on each page (PageSize), even last one

Hi,

I'm using a RadGrid with a fixed height in pixels. I've set the MasterTableView's AllowPaging property to "true" and the PageSize property to "19" (because I want to display 19 rows on each page).

My problem is that when I reach last page, which does not contain 19 elements (unless the total is a multiple of 19 but hey), then on that page the rows take all the available space in height. For example, if a page contains only 2 elements, I'm getting 2 rows each taking 50% of the total height.

Obviously what I would like is the rows height to stay the same accross the pages (I tried setting ItemStyle-Height to a fixed dimension but did not change anything). So, if I have a page with 2 rows, knowing that the PageSize is set to 19, I would like my 2 rows to be followed by the equivalent of 17 empty rows in height.

How can I achieve this?

Hope that makes sense.

Thanks,
Nicolas

Just for clarity sake:

- What I have (1st page on the left, 2nd page on the right, assuming PageSize=19 and I have a total of 20 rows):

RadGrid FilterList not complete

I've got an issue where the filter list is not showing all the list items. The top of the list is cut off and "NoFilter" is not showing. I think it might be a CSS setting but all the attempts to fix have failed. The RadGrid is inside column1 of a two column master page. Also, looks like the list is "double spaced" and therefore making the list longer than it has to be.

Anyone have any suggestions?

Thanks,
David

RadGrid Columns overlap in Mozilla Firefox.

Item Texts in RADGrid columns overlap in Mozilla firefox. I do not want to wrap the text and make it appear on the next line as we have calibrated Row height and Grid Height for specific scenario. I would rather prefer trim the text if it’s length is greater than the column width. Please suggest a way to handle this problem. I have set ClipCellContent OnResize = True. It works fine in IE7 but not in Firefox and Chrome.

NodeDataBound event does not fire

When your TreeView uses data binding the NodeDataBound event will not fire unless your

DataFieldParentID column has a null value. I found this when binding to custom objects; in my application in most cases the top most parent had a null value in the DataFileParentID column. Because it was a custom object (composite object) In rare cases my object was returning a zero length string as parent. This was interpeted as being not a valid parent by TreeView and therefore it wasn't consdered for the root, and therefore, the NodeDataBound event wouldn't fire.

Another clear indicator that this problem is occuring is when the TreeView is displayed on the page as empty.

Hope this helps others as my searches here didn't provide any insight into why the event wasn't firing.

TreeView - decision - data binding?

Hello,

Looking at all the available methods of data binding and code examples i'm having a hard time deciding on how to approach a relatively simple design.

1)
I need to populate a TreeView with data, possibly up to 500 nodes, maybe on demand. I'm using self referencing hierarchical data using ItemID and ParentID. I would like to be able to drag & drop nodes, and save the changes to the database.

2)
I would also like (on another page) to have 2 treeviews populated by separate queries. I would like to drag & drop from one tree to the other (one direction only) single nodes or entire branches. I would like to save the newly edited tree to the database.

Which databinding methods shoudl I use? Should I use a LinqDataSource, manually populate a dataset from LINQ or something else? I guess I would update changes to the database as they are made. I'm thinking of using a floating SortOrder field in the database. Which code samples should I look at ?

Your advice would be greatly appreciated, as I don't want to start in the wrong direction.

Thanks,

Michael

Ajax - User Control - Initiating Control

Hi :)

The scenario I have is this:

A Page containing

AjaxManager
A user control to be shown a little like a dialog
A main form user control

A Main form user control

An initiating user control

So I add a setting to the ajaxmanager that the initiating user control updates the control to be shown

but the initiating user control also updates the Main Form user control

I really want the initiating control to only update the user control to be shown like a dialog.

Does this make sense?
Any ideas?

Cheers Martin
