properties editor doesn't support fields-prompt

hi,
I just upgrade my Aspnet ajax to ver 2011 Q1, my question is: in Grid's properties editor, I couldn't find fields-prompt support for DataKeyNames input, parent table relation defining (as attachment)..., even I've defined the DataSouce name. RadGrid doesn't support this feature or I got the wrong design step?

System.Security.SecurityException is coming while fetching data in radgrid from sqlConnection object
I have uploaded the site to netfirms.com, they are only supporting Medium Trust Level.

I have used templates for editing in radgrid.

filter by DataKeys or DataItem's text?

I am using a RadFilter with a RadGrid. So far I have only got the RadFilter to work when my FilterExpression's FieldName is equal to a GridBoundColumn's DataField.

I have a column where the text displayed to the user is a concatenation of 3 fields from my DataSource. However, I want the user to be able to filter by each of these fields individually. Adding the individual fields as DataKeys did not work. Right now I have it working by having 3 GridBoundColumns with DataField set to each of the 3 individual fields, and Visible=false. Are there any performance implications to this approach? Even if there aren't any, I still think it's messy code. I would prefer to use the DataKey if possible.

I have another column where the value from my DataSource is an int. However, to get the value I display to the user, I cast this int to an enum and call ToString(). I am building my filter expressions programmatically. Right now it seems like I would have to build a RadFilterEqualToFilterExpression<int> for this column. However, all my other columns would use RadFilterEqualToFilterExpression<string>. My code would be much simpler if I could use RadFilterEqualToFilterExpression<string> for all my columns. Is it possible to filter by DataItem["uniqueName"].Text?

Thank you!

Grid FilterRow doesn't render correctly in IE8 compatibility mode

Hi all.

I posted a reply to this post ( http://www.telerik.com/community/forums/aspnet-ajax/grid/grid-renders-differently-from-development-when-in-production.aspx#963065 ) yesterday but wanted to start a fresh post incase no one is monitoring that post any more

I have a grid with a filter row that renders incorrectl when IE8 is used in compatibility mode. I have attached 3 images to show what they look like in different scenarios..

Image 1 shows the header of my grid in IE8 with compatibility mode turned off.
Image 2 shows the same header in the same browser with compatibility turned on.
Image 3 shows the same setup as image2, but with the FilterControlWidth set to 50px, which is much narrower than the filter icon's required space.

The code for the first column (Customer Reference) is shown here...

This is the same code used to generate Image 1 and Image 2.

<telerik:GridBoundColumn

HeaderText="Customer reference"

DataField="External_Document_No"

SortExpression="External_Document_No"

FilterControlWidth="108px"

FilterListOptions="VaryByDataType"

>

<HeaderStyle HorizontalAlign="Left" Width="158px" />

<ItemStyle HorizontalAlign="Left" Width="158px" />

</telerik:GridBoundColumn>

This is the code used to generate Image 3...

<telerik:GridBoundColumn

HeaderText="Customer reference"

DataField="External_Document_No"

SortExpression="External_Document_No"

FilterControlWidth="50px"

FilterListOptions="VaryByDataType"

>

<HeaderStyle HorizontalAlign="Left" Width="158px" />

<ItemStyle HorizontalAlign="Left" Width="158px" />

</telerik:GridBoundColumn>

It seems that the FilterControlWidth option is only setting the textbox and not the overall width of the filter item (the textbox and the filter button)

Any ideas why the filter row doesn't all sit nice and neatly on one row?

Header Item Misalignment

v.2010.3.1317.40

I am using the grid client side databinding with vertical scrolling and static headers. I initially set the page size to 50 so the scrolling takes affect when the grid is bound. On the gui when i change the page size or filter the grid so that the scroll bar becomes unnecessary the grid header and item rows become misaligned. This misalignment happens on IE9/IE9 Compatibility, Chrome, FireFox, and Opera. The grid is in a div width 950px. I have also tried removing all header widths and div width and the misalignment still happens. I am not using ItemStyle-Widths or GridLine properties. Here is the grid and the type of client side databinding. Also i have attached the images of what is happening.

How do i get the header and item rows to align when I change the page size or filter?

I did just see something interesting happen as i was entering this post and retesting the grid. I was using IE9 with the menu bar hidden. I then changed the page size and the grid misaligned. I then clicked alt to show the menu and the grid aligned itself. If i could make the grid do this when after databinding thing would be great.
