Hi Sorin,
Thank you for your interest in Syncfusion Products.
You can retain the selection state for a TabStrip control on a master page when each item redirects to another aspx page by using below code:
[Javascript]
window.onload=function()
{
//Callback to get the previous and current tab selection
CallbackPanel2.callback();
}
[c#]
protected void CallbackPanel2_CallbackRefresh(object sender, Syncfusion.Web.UI.WebControls.Shared.CancellableCallbackEventArgs e)
{
this.previousTabHidden.Value = this.CurrentTabHidden.Value;
//Get Current selection
value = Application["selectedvalue"] as string;
//Get previous selection to remove selection
value2 = Application["curentetab"] as string;
if (value != null)
{
foreach (TabStripItem item in this.TabStrip1.Items)
{
if (item.Selected == true && item.Text == value2)
{
item.Selected = false;
}
if (item.Text == value)
{
item.Selected = true;
}
}
}
}
Please refer the sample in the below link which illustrates the above:
