[CLOSED] Multicombo deselect all problem

Hi,

Can you tell me what's wrong with this code. I would like to deselect all selected items when unchecking the first item. But it's not working:

Code:

<%@ Page Language="C#" %> <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %> <!DOCTYPE html> <html> <head id="Head1" runat="server"> <title>MultiCombo</title> </head> <body> <form id="Form1" runat="server"> <ext:ResourceManager ID="ResourceManager1" runat="server" /> <ext:MultiCombo ID="MultiCombo1" runat="server" Width="260"> <Items> <ext:ListItem Text="Select All" Value="0" /> <ext:ListItem Text="Item 1" Value="1" /> <ext:ListItem Text="Item 2" Value="2" /> <ext:ListItem Text="Item 3" Value="3" /> <ext:ListItem Text="Item 4" Value="4" /> <ext:ListItem Text="Item 5" Value="5" /> </Items> <Listeners> <Select Handler="if (index==0) #{MultiCombo1}.selectAll();"/> <BeforeDeselect Handler="if (index==0) #{MultiCombo1}.clearValue();"/> </Listeners> </ext:MultiCombo> </form> </body> </html> Martin

Hi Martin,

A component instance and an array of selected records are passed to a MultiCombo's Select listener. There is no the index argument. So, a JavaScript error occurs if select an item.

As for deselecting all. The BeforeDeselect listener fires for every deselect items. So, a recursion occurs there.

Though, even if avoid recursion this way:

Code:

<BeforeDeselect Handler="if (!this.beforeDeselectLocked) { if (index === 0) { this.beforeDeselectLocked = true; this.clearValue(); this.beforeDeselectLocked = false; } }"/>

the clearValue method call clear the value, but doesn't clear selection.

Here is a test case to reproduce.

Code:

<%@ Page Language="C#" %> <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %> <!DOCTYPE html> <html> <head runat="server"> <title>MultiCombo</title> </head> <body> <form runat="server"> <ext:ResourceManager runat="server" /> <ext:Button runat="server" Text="Clear" Handler="App.MultiCombo1.clearValue();" /> <ext:MultiCombo ID="MultiCombo1" runat="server"> <Items> <ext:ListItem Text="Item 1" Value="1" /> <ext:ListItem Text="Item 2" Value="2" /> </Items> </ext:MultiCombo> </form> </body> </html>

Works now...using BeforeSelect instead of Select solves the other issue also..

Thanks !
