Disable button by checking validators and invoke server side event

Scenario: - Check whether any validator is triggered. If triggered then don't postback and don't disable the button. If all validators are valid then disable the button and call the server side event.

Solution:-
To solve this scenario , I found out one simple solution using javascript

<script type="text/javascript" language="javascript">
function fnValidate(obj)
{
for(var i=0; i<Page_Validators.length; i++)
{
ValidatorEnable(Page_Validators[i]);

if (Page_Validators[i].isvalid)
{
obj.disabled=true;
}
else
{
obj.disabled=false;
break;
}
}

if (obj.disabled==true)
{
<%=Page.GetPostBackEventReference(btnSubmit)%> }

}

</script>

Call this javascript function in button's OnClientClick property as follows.

<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="fnValidate(this);" CausesValidation="true" OnClick="btnSubmit_Click"/>

Enum to Datatable Function Using Vb.net

In this post I have given simple vb.net snippet to convert Enumeration data to datatable, so that we can use the enumeration datas as master table or lookup table

Shared Function EnumToDataTable(ByVal typEnum As Type) As DataTable
Dim ddlTypnames() As String = [Enum].GetNames(typEnum)
Dim arrddlTypVals As Array = [Enum].GetValues(typEnum)

Dim dt As New DataTable
Dim dr As DataRow

dt.Columns.Add(New DataColumn("values", GetType(Int32)))
dt.Columns.Add(New DataColumn("names", GetType(String)))
Dim i2 As Integer
For i2 = 0 To ddlTypnames.Length() - 1
dr = dt.NewRow()

dr(0) = CInt(arrddlTypVals(i2))
dr(1) = ddlTypnames(i2)

dt.Rows.Add(dr)
Next i2

Return dt
End Function

Using this function

Dim dt As DataTable
dt = EnumToDataTable(GetType(EnumSample))

Happy Coding!
