Hello!

I am trying to implement the similar to this
http://demos.telerik.com/ASPNET/prometheus/Dock/Examples/DynamicDocks/DefaultCS.aspx article functionality.

I also have 2 RadZones (the second is like a cart).

But the difference is:
instead of "Add Dock" i have "Search" button. So on its click I have to completely change (clear and add found items) the first RadZone and, possible some elements from the second one.

My current Search method is:


private void SearchSongs()
zoneSearch.Controls.Clear(); 

zoneSearch.Docks.Clear();

CurrentDockStates.Clear();

DataTable dt = <-- getting data

RadDock rd = new RadDock();

rd.UniqueName =

Guid.NewGuid().ToString();

rd.Text = dr.Title;

rd.Title = dr.Title;

rd.ID =

string.Format("RadDock{0}", rd.UniqueName);

rd.DockMode =

DockMode.Docked;

rd.Commands.Add(

new DockCloseCommand());

rd.Commands.Add(

new DockExpandCollapseCommand());

rd.Command +=

new DockCommandEventHandler(dock_Command);

CreateSaveStateTrigger(rd); //  <--   but here an exception occured. actually, inside the method here: UpdatePanel1.Triggers.Add(saveStateTrigger);

zoneSearch.Controls.Add(rd);

can you give me a clue how should I manage this situation?

and what should I do to add another button handler (for instance, search2Button).

I hope the provided code is enough. All the code similar to the sample's one and another commands connected to moving, closing etc Docks works ok. The only problem (and difference) is in Search button work.

Thank you and the best regards,
Boleslav

1. Subscribe to the ItemCommand event
2. Determine whether or not the command being fired is a filter command
3. Determine whether or not the filter command matches a given column
4. If so, string parse the entire sql where clause used by the grid so that you can parse out the particular predicate you're interested in
5. Then, string parse the predicate to access the given value you want to reformat
6. Reformat that value and replace it in the where clause
7. Store the reformatted where clause somewhere because you'll then have to...
8. Subscribe to the NeedDataSource event
9. Replace the grid's default FilterExpression with your custom version
