How to get the value of a textbox which is inside a webdatamenu?
posted

This is my webdatamenu:

<ig:WebDataMenu ID="Mimenu" runat="server" Width="100%" Height="40px">
<Items>
<ig:DataMenuItem Key="Numero" >

<Template>

  <%--The value of the text box is according to what the user enters ... although by default is number 1 --%>


<asp:TextBox runat="server" ToolTip="N&#250;mero" Key="NumeroP"
Rows="0" Columns="0" Width="30px">1</asp:TextBox>


</Template>
</ig:DataMenuItem>

</Items>
</ig:WebDataMenu>

---------------------------------------------------------------

in the CondeBehind

int NoP = Convert.ToInt32(Mimenu.Items.FindDataMenuItemByText("NumeroP").Text);

Here I want to get the value that brings the box but I can not always throws me an error:

Object reference not set to an instance of an object.

Thanks very much!

Before it got so

<igtbar:ultrawebtoolbar id="Mimenu" runat="server" Width="100%" Height="30px" ItemWidthDefault="150px">


<Items>

<igtbar:TBTextBox Rows="0" ToolTip="N&#250;mero" Key="NumeroP" Columns="0">
</igtbar:TBTextBox>
</Items>
</igtbar:ultrawebtoolbar>

------------------------------------------------------------------------------------------

int NoP = Convert.ToInt32(Mimenu.Items.FromKeyTextBox("NumeroP").Text);

    Hello Mary,

    First you would need to find the DataMenuItem that contains the TextBox control:

    

    DataMenuItem item = Mimenu.Items.FindDataMenuItemByKey("Numero");

    Once you have this, then you can use FindControl get access to the control within the Template:

    

    TextBox numeroP = item.FindControl("NumeroP") as TextBox;
    

    if (numeroP != null) {
    

       int NoP = Convert.ToInt32(numeroP.Text);
    

    }

    For more information about using FindControl, please see the MSDN documentation on the method.
