Tab container

hi all,

i have placed the tab container in side a datagrid. tab container will appear in the item command of datagrid. if i set the active tab index as zero. i got some error.

57 line 17 char

argument out of range exception

1495 line 38 char

this.get_element().style is null or not an object.

if i remove that active tab index property tab container works fine.

how to close the tab container?

Hi Balaji,

Can you show me your relevant code so that I can reproduce your issue?
A stripped simpler version of your code would be better.

Looking forward to your reply.

hi,

here is my code snippet

protectedvoid dlHostels_ItemCommand(object source,DataGridCommandEventArgs e)

{

tabcontainer tbc=new tabcontainer();

tbc = (TabContainer)dlHostels.Items[e.Item.ItemIndex].FindControl("TabContainer1");

Label lblInfo =newLabel();

TabPanel tp = new tabpanel();

tp.controls.add(lblinfo);

tbc.controls.add(tp);

//i have added three panels to this tabcontainer.

tbc.activetab=0; // problem with this tabindex. if i didnt mention anything then it works fine.

}

Tab Index

hai,

i had placed tab control inside multiview panel which has the view index 1.in the page load event i show only view index 0.my problem is when i click the the button to change view index to 1,tab panel does not appear properly[i.e css not applied] and active index changed event also does not fire.how can i use tab panel inside multiview with visibility set to false.

thanks in advance

Hi,

Is your tab is displaying?,,,,,or not displaying....tab is usually coming with a default css (tab__xp)...if its ok..then check your web config..is it configured for ajax supporting...i think u created your website using File->Newwebsite->Asp.net website instead of this use File->New->website->Ajax enabled website...than ajax supporting tags will automatically comes in web config...please confirm this..if its ok then check your bin folder from ajaxtoolkit dll,if its not there copy that dll to bin folder..

Hi Kumaran,

The sample you provided itself is correct.

As the error message indicates, please don't use code block in your page, use assignment in code behind instead.
