Async request failed error
New Discussion
Hi
I've added the Webdata grid in the ASPX (vb.net) page and here is the code snippet of the source page (HTML)
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
<asp:Button ID="Button1" runat="server" Text="Button" />
<ig:WebDataGrid ID="WebDataGrid1" runat="server" Height="350px" Width="400px">
<Behaviors>
<ig:Selection CellClickAction="Row">
<AutoPostBackFlags CellSelectionChanged="True" ColumnSelectionChanged="True"
RowSelectionChanged="True" />
</ig:Selection>
<ig:RowSelectors>
</ig:RowSelectors>
<ig:Activation>
</ig:Activation>
<ig:EditingCore>
</ig:EditingCore>
</Behaviors>
</ig:WebDataGrid>
<ig:WebScriptManager ID="WebScriptManager1" runat="server">
</ig:WebScriptManager>
</form>
</body>
</html>
In the code behind, the code snippet is
Public Class personXXX
Public name As String
Public age As Int16
Public gender As String
Public status As Boolean
Public State As String
End Class
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
WebDataGrid1.EnableDataViewState = True
BuildGrid()
Else
End If
End Sub
Private Sub BuildGrid()
Dim dataTab As New DataTable
Dim colDB As New DataColumn
Dim objRow As DataRow
WebDataGrid1.Rows.Clear()
colDB = New DataColumn("RowID", Type.GetType("System.Int16"))
dataTab.Columns.Add(colDB)
colDB = New DataColumn("Name", Type.GetType("System.String"))
dataTab.Columns.Add(colDB)
colDB = New DataColumn("Age", Type.GetType("System.Int16"))
dataTab.Columns.Add(colDB)
colDB = New DataColumn("Gender", Type.GetType("System.String"))
dataTab.Columns.Add(colDB)
colDB = New DataColumn("Status", Type.GetType("System.Boolean"))
dataTab.Columns.Add(colDB)
colDB = New DataColumn("State", Type.GetType("System.String"))
dataTab.Columns.Add(colDB)
Dim per1 As New personXXX With { _
.name = "Eliza", _
.age = 27, _
.gender = "Female", _
.State = "CA", _
.status = True
}
Dim per2 As New personXXX With { _
.name = "Sarah", _
.age = 22, _
.gender = "Female", _
.State = "GA", _
.status = True
}
Dim per3 As New personXXX With { _
.name = "ema", _
.age = 22, _
.gender = "Female", _
.State = "MD", _
.status = False
}
Dim per4 As New personXXX With { _
.name = "rachel", _
.age = 20, _
.gender = "Female", _
.State = "MD", _
.status = True
}
Dim per6 As New personXXX With { _
.name = "jim", _
.age = 22, _
.gender = "Male", _
.State = "MD", _
.status = True
}
Dim per5 As New personXXX With { _
.name = "jack", _
.age = 32, _
.gender = "Male", _
.State = "CA", _
.status = True
}
Dim personArr As personXXX() = {New personXXX(), per1, per2, per3, per4, per5, per6}
For introw = 1 To 6
objRow = dataTab.NewRow()
objRow(0) = introw
objRow(1) = personArr(introw).name.ToString
objRow(2) = Integer.Parse(personArr(introw).age)
objRow(3) = personArr(introw).gender.ToString
objRow(4) = personArr(introw).status
objRow(5) = personArr(introw).State
dataTab.Rows.Add(objRow)
Next
WebDataGrid1.DataSource = dataTab
WebDataGrid1.DataBind()
End Sub
When I click on the checkbox in the grid, I get an error, see attached.
Any help?
