How to change gridpanel selection model selection mode (single/multiple) from client side (javascript)?

[reezvi]

Hi guys,

Is there a way to change gridpanels selection model using javascript?

Hers is my problem - my target gridpanel is with checkbox selection model (by default single select). It's in an user control page. When using this user control inside an ext window, i want to change selection model's selection mode to multi select based on some conditions.

I tried changing the selection mode from code behind but all without any affect. Possibly a viewstate issue. Here's a snippet i tried, but it resulted the grid to disappear!! :(

grdAuditableUnit.SelectionModel.Clear();  
//CheckboxSelectionModel csm = new CheckboxSelectionModel();  
//csm.ID = "CheckboxSelectionModel1"; 
//csm.CheckOnly = false;  
//grdAuditableUnit.SelectionModel.Add(csm); 
grdAuditableUnit.SelectionModel.Add(new CheckboxSelectionModel { CheckOnly = false });  
///grdAuditableUnit.Reconfigure(); 
grdAuditableUnit.Render();

Any help with small exaple is highly appreciated. Thanks

Hi,

Here's the snippet under Listener for changing selection model of a grid from client side - #{yourTargetGridPanel}.getSelectionModel().singleS elect=true;

If you set the value to 'false', it will by default prepare the selection model for multi select.

Hope it helps.
