Hiding column in hierarchical grid: formatting issues

I have a hierarchical grid where the parent and the children all use the same column headers such as follows. Everything looks fine when I show the Action column. When I hide the Action column, however, the column's contents remain in the child rows (e.g., where the Type is Child in the example below) and the formatting is messed up (see below).

ActionColumn.Visible = true;

ID Parent Name Type Action

1 - Note Parent O:E:D

2 1 Reply Child O:E

3 2 Reply Child O:E

4 - Note Parent O:E:D

ActionColumn.Visible = false;

ID Parent Name Type

1 - Note Parent

2 1 Reply Child O:E

3 2 Reply Child O:E

4 - Note Parent

I'm setting the grdNotes.Columns.FindByUniqueName("Actions").Visible = ShowActionColumn (where ShowActionColumn is a bool property set by the user preferences) in the Page_Load event.

What else needs to be done to hide the contents of the child row's column contents? (I've already tried setting toolbar.visible=false, but to no avail.)

FWIW, here's the definition of the grid:

<telerik:RadGrid ID="grdNotes" runat="server" OnColumnCreated="grdNotes_ColumnCreated"

RadGrid display bug?

Hello!

I have 2 problems with displaying RadGrid.

I have attached a picture displaying it.

First problem (RED square): Every time there is a vertical scroll displayed we get this strange white space. Any idea how to fix this?

Second problem (BLUE square) apears when client side colum resizing is possible. We think that the last column should always be connected with the right side of the grid just like the fist one is connected with the left side.

Thanks for your help!

Add tool: <tool name="RelativePosition" />

Hi,

I use the editor for subcontent on pages, and therefor the AbolutePosition is no go.

Then the content is shown relative to the top left corner of the browser, and not the DIV where I place the content from the Editor.

So please add RelativePosition as well :-)

Best regards,
Christian

Self Hierarchy and DetailTables

I have a Grid setup with a self hierarchy with additional detail tables. When I expand a top level entry, I correctly see the children (both the linked detailtables and also the self hierarchy entries). But when I expand the next level of a entry from the self hierarchy, the linked detailtables are not displayed.

I am using the NeedDataSource method on the Grid, which checks if the event is from the detail table or not.
And also using the DetailTableDataBind as described at http://demos.telerik.com/aspnet-ajax/grid/examples/programming/detailtabledatabind/defaultcs.aspx, and when I step through the code in the debugger, the DetailTableDataBind never gets called for the detail tables when I expand below the first level.

An example of what I am trying to do is a Folder table and a File table. You can have Folders within Folders, and Files in Folders. If I expand the top level Folder, I can correctly see the child folders and files, but when I expand one of the child folders, it only shows folders. It seems to skip over the detailtables.

Is this a bug, or might I be overlooking something?

Thanks,
Eric

Change Web Service method client side?

I am looking to change the web service method via a client side, and was wondering if there is a way to do it. I could not find one myself.

The context I am using it in is alongside a dropdownlist. The combobox searches for records based on the type selected in the dropdownlist. I change the method for when the list changes. I am trying to reduce my server side calls, and would love to be able to handle all this clientside.

Default expand

I have a very, very basic grid with a nestedviewtemplate and would like for it to be defaulted to be expanded. I thought that was the default already but it isn't. What am I doing wrong?

Get/Set Column Width from Client-side

Hi there,

I would like to store and restore column widths of a RadGrid from Javascript but unfortunately I can't find a method to set the width of a column. Is there such a function in the client-side API?

Best regards,

[Solved] ToolBarMode splits a toolbar

Hi,
I've been customising the toolbars and going through the instructions quite heavily the last couple of days. I've noticed a few quirks that I'll probably ask a few questions about later, but this one bugs me:

When changing the following property to 'Default', one of the menu bars is chopped off and the toolbar icon that is supposed to be on the same line is now on the line below.

    
            <property name="ToolbarMode">ShowOnFocus</property>

How can I prevent this from happening? The toolbar above and below this are working fine. Changing it back to 'ShowOnFocus' it works normally again.

Thanks,
Jason.
