Edit mode stays after rebinding the datasource

For example:

1. I put row(index) 1 in edit mode

2. page posts back and I rebind a new datasource

3. after postback row still expanded and in edit mode even.

I want to clear all the expanded and edit mode items after post back.

I call this code from a button's onclick event:

                     private void LoadGrid(Int64 p)         
                    {         
                        grd.Rebind();         
                        grd.DataSource = BL.GetAll(p);         
                        grd.DataBind();         
                    }

Filter multivalued column using radcombobox

I want to use a radcombobox to filter a radgrid column. There is a great example of doing this and I can tweak the example to use a checkbox plus label template in the combo box.

I am running into problems when the column is not just a string field but a multivalued field. For example I have a Person entity and that person has a property that is a list<School>. We bind the column to the Schools property and use a repeater in the template to display the schools. I can successfully build the combobox but am having trouble filtering for records where people only have the selected schools.

Radgrid performance large table with Scrolling, Filtering, Sorting

Hello,

I would like to present about 10,000 records per page, I might need paging if more than 10000 records are on the table (Sql Server db).

I need filtering, and sorting, and scrolling.

I know there are several techniques to optimize radgrid, but I would like to know...

Which technique should I look at for loading and displaying data in this case?

Thanks,
Simone

AutoPostBackOnFilter="True" ShowFilterIcon="False"

ASP.NET v4.0.30319
IE 8.0.7600.16385
Windows 7
Telerik.Web.UI 2011.1.519.40

When i have a

telerik:GridBoundColumn

with these set

AutoPostBackOnFilter="True" ShowFilterIcon="False"

and I use the tab key to move off the filter textbox sometimes it does not filter and sometimes it does. Also if it filters 2 times in a row it locks the textbox from entry until I click another filter icon or paging control on the screen. The tab button navigates to another textbox that does not have AutoPostBackOnFilter or ShowFilterIcon set at all. The text box locking has existed in the last 2 version as well. I just upgraded to test if it fixes it.
