    hi,

    i used the textbox inside the panelbar i used the following codes the find the controle but the value i'm getting from the textbox is null

    foreach (RadPanelItem PanelItem in RadPanelBar1.GetAllItems())
    {
    RadTextBox txtAge = RadPanelBar1.FindControl("txtAge") as RadTextBox;
    RadTextBox txtWeight = RadPanelBar1.FindControl("txtWeight") as RadTextBox;
    health.Age = Convert.ToInt32(txtAge.Text);
    health.weight = Convert.ToInt32(txtWeight.Text);
    }

    the value of txtAge and txtWeight is always null even if i gave different value in runtime
    how to get the value of the textbox entred in run time.

    Regards

    Hi Priya,

    You should first find the item which contains the textbox and then use FindControl method as it's demonstrated here.

    This is a bit of a crosspost from the ASP.NET forum (where I erroneously posted it in the first place)

    Using an item template makes the process in the demos (and the helpfile) a bit hard to follow.
    This is because in the walkthrough for placing controls in an itemtemplate we are required to add a radpanelitem with no text.

    So this code, as recommended in the demo and helpfile:
    Dim txtbox as textbox = DirectCast(RadPanelBarName.FindItemsByValue("RadPanelBarValue").FindControl("ControlID"), textbox)
    will not work


    I have found that it works if you add the reference to the item containing the template first, such as:
    Dim txtbox as textbox = DirectCast(RadPanelBarName.FindItemsByValue("RadPanelBarValue").Items(0).FindControl("ControlID"), textbox)



    Note where I reference "Items(0)" and call its FindControl method.
