Hello,

I am trying to apply a filter on initial load but continue to get an error. I have followed this example http://www.telerik.com/help/aspnet-ajax/grdapplyingdefaultfilteroninitialload.html which seems pretty simple but I get an error: "Expression expected",.. "Exception Details: System.Web.Query.Dynamic.ParseException: Expression expected". Any help would be great.

Thanks

How to get filter to work with GridDropDownColumn ListTextValue instead of PK/IDs?

Is there a way to make the filter work with text entered for a RadGrid GridDropDownList and respect the lookup values (ie a databound lookup) for ListTextField instead of the numeric ID?

Also, similar question: When a GridDropDownList column is grouped in RadGrid, the ID is displayed in the group header instead of the databound ListTextField value. So it shows xxx: 1830 instead of xxx: Bob Smith ?

Problem with filtering the Radgird.

I have a grid with three columns and I want user to enter their filter values and then click "Search Filter" button which is outside the grid.
Two columns have a textboxes for filter and the last column has a combobox with checkbox in it.
Everything works fine when the textbox columns are filtered. Problem occurs when the combobox with checkbox is selected. it returns no data found. You can see the image attached and also Client and Serverside codes.

Do let me know where am I going wrong...Any help will be appreciated.

Thanks

Hidding "InitInsert" button when in edit mode

Hi,

I'm trying to accomplish this: I need to hide my "Add own content" buttons when user enters Insert mode. To handle this, I subscribed ItemCommand event and check if CommandName is "InitInsert". If is, I set EventSource element visibility to false. That works great.

What's giving me hard time is EmptyDataTemplate. I placed my "Add own content" button in this template, but then after clicking it, layout changes, so of course setting visibility of this button to false have no meaning. I figured out, that I could handle LayoutCreated event and then find this button and hide it. There I encountered another problem: how to find out, whether I'm in Insert mode or not? InsertItem property of ListView is null, when I know that I entered insert mode. I looked through other properties and cannot seem to find out how to verify mode in which ListView is.

My question are:

1. How can I find out whether I'm in insert mode or not?

2. Is there any other way I can hide "add own content' button when in insert mode?

Thanks in advance,

Pako
