Facing problems when i add tabs dynamically from code.

[Subramanya Bhat]

HI,

I am having a requirement wherein i want to add the tabs based upon users selection dynamically thrugh code. I created a TABSTRIP with a default tab and a MULTIPAGE with a default page and gave a dropdown wherein user selects the value and click add tab button.

PROBLEM: When i click on the ADD TAB button first time the tab is getting created with the page but consequent clicks erases the old Pages.

heres my code

private bool CreateTab(string e)
{
if (!CartTabStrip.Items.Contains("Tab_"+ e))
{
TabStripItem TabItem = new TabStripItem();
TabItem.Text = e;
TabItem.ID = "Tab_" + e;
TabItem.PageViewID = "Page_" + e;
CartTabStrip.Items.Add(TabItem);
return true;
}
else
{
return false;
}
}


private void CreatePage(string e)
{
PageView TabPage = new PageView();
TabPage.ID = "Page_" + e;

TextBox text = new TextBox();
text.Text = e;

TabPage.Controls.Add(text);

CartTabs.Pages.Add(TabPage);
}

Thanks Rekha,

It helped.

But the problem is not solved fully.

1) This solution doesnt work if i put the menu control inside the Update Panel control to acheive Ajax Functionality.

2) What if the multipage is having a Gridgrouping control instead of textbox. How will you maintain the state of the existing controls.

Hi Subbu,

Thank you for being patient.

Regarding,
1) This solution doesnt work if i put the menu control inside the Update Panel control to acheive Ajax Functionality.
Please refer the below link for sample files which illustrates the working of Menu control inside the UpdatePanel,

2) What if the multipage is having a Gridgrouping control instead of textbox. How will you maintain the state of the existing controls.
Please refer the workaround sample containing a Gridgrouping control in PageView along with the video clip,

Hi Ali,

Thank you for contacting Syncfusion support.

We are unable to reproduce the issue reported that the pages are lost on adding newer pages from code behind. Kindly ensure whether you have provided unique ID for the PageView created dynamically. We have prepared a sample that allows you to add new TabItem integrated with new PageView created dynamically. Please check whether the issue reproduces in the shared sample. If not modify the sample to reproduce the issue at our end so that we can provide you an alternative solution.
