Dear My Friends of Senior Programmer,

Please Help me, my Problem is cannot retrieve and load the color from my XML file into datagridview (EVENT: FORMTES3_LOAD). the application isn't error but the display of my Datagridview become irregular.

below is my FULL Source Code:

Note : the component is windows form, button, colordialog and datagridview



Imports System
Imports System.IO
Imports System.Xml

Public Class FormTes3

Dim Doc As XmlDocument = New XmlDocument

    Dim rowClicked As Integer
    Dim colorName As String

Private Sub CreateNewColorElement(ByVal rowID As Integer) ', ByVal columnIndex As Integer)

        'Create Row Node & ID Attribute
        Dim rowNode As XmlNode = Doc.CreateElement("Row")
        Dim idAttribute As XmlAttribute = Doc.CreateAttribute("rowID")
        idAttribute.Value = rowID.ToString
        rowNode.Attributes.Append(idAttribute)

        'Column Node
        Dim columnNode As XmlNode = Doc.CreateElement("Profile")

        'BackColor
        Dim backColor As XmlAttribute = Doc.CreateAttribute("BackColor")
        backColor.Value = colorName
        columnNode.Attributes.Append(backColor)

        rowNode.AppendChild(columnNode)
        Doc.DocumentElement.AppendChild(rowNode)

    End Sub


Private Function GetHexColor(ByVal colorObj As System.Drawing.Color) As String
        Return "#" & Hex(colorObj.R) & Hex(colorObj.G) & Hex(colorObj.B)
    End Function


    Private Sub DataGridView1_MouseUp(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseUp

        Dim result As DialogResult

        If e.Button = Windows.Forms.MouseButtons.Right Then

            rowClicked = DataGridView1.HitTest(e.Location.X, e.Location.Y).RowIndex

    result = ColorDialog1.ShowDialog()

            If result = DialogResult.OK Then

                Dim rowIndex As Integer = rowClicked

   DataGridView1.Rows(rowClicked).DefaultCellStyle.BackColor = ColorDialog1.Color   'Running Well

                colorName = GetHexColor(ColorDialog1.Color)
CreateNewColorElement(rowIndex)

 ElseIf result = DialogResult.Cancel Then

                Return

            End If

        End If

    End Sub



  Private Sub FormTes3_Load(sender As Object, e As System.EventArgs) Handles Me.Load

        ' Populate the grid
        DataGridView1.Columns.Add("Column1", "Column 1")
        DataGridView1.Columns.Add("Column2", "Column 2")
        DataGridView1.Columns.Add("Column3", "Column 3")

        DataGridView1.Rows.Add("A", "B", "C")
        DataGridView1.Rows.Add("A", "B", "C")
        DataGridView1.Rows.Add("A", "B", "C")
        DataGridView1.Rows.Add("A", "B", "C")
        DataGridView1.Rows.Add("A", "B", "C")

        'In your constructor 
        Doc.AppendChild(Doc.CreateElement("DataGridView"))

        If System.IO.File.Exists((Application.StartupPath + "\test.xml")) Then
            Dim row As Integer
            Dim column As Integer
            Dim backColor As String

            Doc = New XmlDocument
            Doc.Load((Application.StartupPath + "\test.xml"))

            For Each node As XmlNode In Doc.SelectNodes("//Row")
                row = Convert.ToInt32(node.Attributes("rowID").InnerText)
                MsgBox(row)

backColor = node.FirstChild.Attributes("BackColor").InnerText
                MsgBox(backColor)

                DataGridView1.Rows(row).DefaultCellStyle.BackColor = Color.FromName(backColor)


  Next

        End If

    End Sub



    Private Sub FormTes3_FormClosing(sender As Object, e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
        'Doc.Save((Application.StartupPath + "\DataGrid.xml"))

        Dim saveFile As SaveFileDialog = New SaveFileDialog
        saveFile.InitialDirectory = Application.StartupPath
        saveFile.Filter = "XML files (*.xml)|*.xml"

        Dim dr As DialogResult = DialogResult.Yes

        If (MessageBox.Show("Do you want to save XML Style?", "Grid Style", MessageBoxButtons.YesNo, MessageBoxIcon.Question) = dr) Then
            If (saveFile.ShowDialog = DialogResult.OK) Then
                Doc.Save(saveFile.FileName)
            End If

        End If

    End Sub



End Class





Thank you in advance for any help you can provide, my brothers :D

Your problem seems to be how you read you XML file. You could do something like this:

Dim name as string
 
 Public Sub Load(ByVal p_XMLfilename As String)
        XMLFilename = p_XMLfilename
 
        Dim x As New System.Xml.XmlDocument
        x.Load(p_XMLfilename)
 
        Dim x_nodes As System.Xml.XmlNodeList = x.SelectNodes("DataGridView")
        For Each node As System.Xml.XmlNode In x_nodes 
 
            For Each node2 As System.Xml.XmlNode In node
                Select Case node2.Name
                    Case Is = "FirstName" : name = node2.InnerText
                   
                End Select
            Next
 
        Next
    End Sub


There also seems to be a problem regarding the storage of the values in you xml document.
