Hi all,

I have combobox Incidenttype(label of combobox) in my application in which i am doing the validation like if someone has not chosen anything in the combobox,it will throw exception that IncidentType Input is not in correct format.

I want to change the Exception message to Please Selcet value in Incident type.
Below is my code .

Xaml

<toolkit:datafield isrequired="True" label="Incident Type" verticalalignment="Center" xmlns:toolkit="#unknown">
<simstagcombobox verticalalignment="Center" horizontalalignment="Left" height="25" width="220" tagtypeid="9" selectedvalue="{Binding IncidentType, Mode=TwoWay }">

Code:
Public Property IncidentType As Guid
Get
Return _guid1
End Get
Set(value As Guid)
_guid1 = value
End Set
End Property

Please provide some solution it very urgent.

Hi,
Check the value before set. Below is the code sample

private IncidentType guid;
public IncidentType Guid
{
get
{
return guid;
}
set
{
if (value == null)
{
throw new Exception(Please Select value in Incident type.);
}
/* set the value here */
}
}

I have already tried it .but if we dont select any thing in combobox set doesn't hit because I am binding through selectedvalue.
