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="Número" 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="Número" Key="NumeroP" Columns="0"></igtbar:TBTextBox></Items> </igtbar:ultrawebtoolbar>
------------------------------------------------------------------------------------------
int NoP = Convert.ToInt32(Mimenu.Items.FromKeyTextBox("NumeroP").Text);
Hello Mary,
The event is fired because you have AutoPostBackFlags-ItemClick set to "On". What you can do however is handle the ItemClick JavaScript event for the control and cancel it if the item's key is "Numero". For more information please see the following thread:

Thanks very much
I was a big help
But now I find detail, if I want to enter a value in the text box automatically sends me to the event webdatamenu and I can not enter my courage ... do not know why this happens or I am doing wrong
sorry for the inconvenience that may have caused my questionthank you very much
<ig:WebDataMenu ID="Mimenu" runat="server" Width="100%" Height="40px"
AutoPostBackFlags-ItemClick="On" OnItemClick="BH_ButtonClicked"
><Items><ig:DataMenuItem Key="Numero" ><Template>
<asp:TextBox runat="server" ToolTip="Número" Key="NumeroP"Rows="0" Columns="0" Width="30px">1</asp:TextBox>
</Template></ig:DataMenuItem></Items></ig:WebDataMenu>
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); }
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.
