[CLOSED] DirectEvent tabchange in tabpanel tab.items.count always 0 on server side.

[ViDom]

Hi,

similar question being asked before here is link: http://forums.ext.net/showthread.php...count-always-0

but I need to use DirectEvent in my case is there any way for getting this items count and pass it through extraparams or something like that?

Edit:
I found something like this :

"tab.items.getCount()"

but how to pass it through extraparams?

Regards,

Hi @ViDom,

Example

<ExtraParams>
    <ext:Parameter Name="count" Value="tabPanel.items.getCount()" Mode="Raw" />
</ExtraParams>

Access it in the DirectEvent handler this way.

e.ExtraParams["count"]

Hi @ViDom,

Example

<ExtraParams>
    <ext:Parameter Name="count" Value="tabPanel.items.getCount()" Mode="Raw" />
</ExtraParams>

Access it in the DirectEvent handler this way.

e.ExtraParams["count"]

That's my point but it's throw exception :

Property 'ExtraParams' does not have a property named 'Name'.

Maybe I doing something wrong? here's my code:

<ext:TabPanel ID="tPanel" AutoHeight="True" runat="server" Height="40" Border="false" Collapsed="True" Visible="False"
            Collapsible="True" Title="Zlinkowane listy" ActiveIndex="0">            
            <DirectEvents>
                <TabChange Before="if (!this.ignoredFirstTabChange) { this.ignoredFirstTabChange = true; return false; }" OnEvent="tPanel_TabChange">
                    <ExtraParams Name="count" Value="tab.items.getCount()" Mode="Raw"></ExtraParams>
                </TabChange>
            </DirectEvents>
        </ext:TabPanel>

btw. your code

tabPanel.items.getCount()

will produce javascript error tabPanel is undefined in sencha docs there is tab element in tabChange event;)

Edit solution for my problem:

<ext:TabPanel ID="tPanel" AutoHeight="True" runat="server" Height="40" Border="false" Collapsed="True" Visible="False"
            Collapsible="True" Title="Zlinkowane listy" ActiveIndex="0">            
            <DirectEvents>
                <TabChange Before="if (!this.ignoredFirstTabChange) { this.ignoredFirstTabChange = true; return false; }" OnEvent="tPanel_TabChange">
                    <ExtraParams>
                            <ext:Parameter Name="count" Value="tab.items.getCount()" Mode="Raw" />
                    </ExtraParams>
                </TabChange>
            </DirectEvents>
        </ext:TabPanel>

Please try this.

Value="this.items.getCount()"

[ViDom]

Please try this.

Value="this.items.getCount()"

there is no problem with

Value

there is error occured because ExtraParams does not contain property named

Name

Is it normal? because I've no warning in markup (normally resharper make warning/errors if something does not exist.)

for clear all doupts:

I don't need to count of tabs in tabPanel(your code does that) but what I need is get count of items in specific activated tab:)

Please have another look at my example. You missed <ext:Parameter>.

[ViDom]

Please have another look at my example. You missed <ext:Parameter>.

Yeah that was the problem. Now I feel like a total noob in ext.net :(

Thanks again Daniil your help is invaluable:)
