Questions on UI for ASP.NET AJAX Forum

Hi,

I have a multiple row grid, where I want its initial state to be all inline editable. The user can then immediately start entering the details into the fields.

When the user saves the grid, all fields are saved, and any field that has been provided with valid data, becomes a plain text link (which will link to something else on click) - IE its no longer an editable field but a plain text link.

Therefore I start with a fully inline editable grid, which becomes a mixture of inline editable and plain text fields, depending on what has been entered.

Could you advise how this could be acomplished with telerik grids as I can't see anything like this in a demo.

Thanks

[Solved] Block scroll on dragging

Hi all,
I've a radgrid with scrolling enabled, and I should drag a row to a radtreeview. Everything works fine except dragging to a node located south-west (or south) of the grid. In this case, drag and drop works well, but during dragging radgrid starts scrolling until I drop the row.
Any ideas to solve this?
Thanks

Diffrent ascx in the EditForm for Grid

Hello,

I have a RadGrid and I have two diffrent ascx files.
I want to dynamicly load one or the other when the user press the Editbutton is this possible?

I understand that I can set a ascx to load with the

EditFormSettings-UserControlName

But that will set only one ascx for my whole grid. When the user press the Editbutton I have to check that row/item and if a specific Colum has value "1" then I want to show one ascx if it has something else I want to show the other. I tried to catch the ItemDataBound event and change the

RadGrid1.MasterTableView.EditFormSettings.UserControlName

To something else but I guess that is to late and that the usercontrol has already been loaded at this point.
Can I in some way set every row/item to have a diffrent usercontrol open when edit is pressed, or is there another event that I can catch BEFORE the control gets loaded?

Thanks in advance.

Help debugging AJAX behavior

I can't figure out why some pages require me to have a proxy manager control, while others are AJAXified automatically...

my scenario:

masterpage: <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"/>
page: (with 2 usercontrols, uc1 affects uc2)

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="uc1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="uc2" UpdatePanelRenderMode="Inline" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

uc1: has a radgrid - need an ajaxmanagerproxy on the page with the radgrid updating itself in order for the the page to update. All controls need to be included as an ajaxsetting to update.
uc2: all controls post back within the usercontrol, no ajaxmanagerproxy needed

Any ideas on what this can be or how I can figure out what's happening?

Thanks,
Reuven
