How to load grid based on values in xml file?

Hello,

I'm trying to load several grids based on the values in my xml file. For example my xml file is in the following format:

<?xml version="1.0" standalone="yes" ?> 
- <Root>
  <NSN_ID>1</NSN_ID> 
  <NSN>1305-00-028-1111</NSN> 
  <Type>1</Type> 
  </Row>
- <Row>
- <Root>
  <NSN_ID>2</NSN_ID> 
  <NSN>1305-00-028-1112</NSN> 
  <Type>1</Type> 
  </Row>
- <Row>

- <Root>
  <NSN_ID>3</NSN_ID> 
  <NSN>1305-00-028-1113</NSN> 
  <Type>1</Type> 
  </Row>
- <Row>
  <NSN_ID>4</NSN_ID> 
  <NSN>1305-00-028-1114</NSN> 
  <Type>2</Type> 
  </Row>
- <Row>
- <Row>
  <NSN_ID>5</NSN_ID> 
  <NSN>1305-00-028-1115</NSN> 
  <Type>2</Type> 
  </Row>
- <Row>
  <NSN_ID>3</NSN_ID> 
  <NSN>1305-00-028-1116</NSN> 
  <Type>3</Type> 
  </Row>
- <Row>
  <NSN_ID>4</NSN_ID> 
  <NSN>1305-00-028-1117</NSN> 
  <Type>4</Type> 
  </Row>
  </Root>

I would like to load Grid1 with NSN values where Type = 1, Grid2 with NSN values where type = 2, Grid3 with NSN values where Type = 3 etc..

Open in new window

How do I accomplish this when in the load event of my windows form?

Thank you.

What you can do is read the whole XML, get the structure according the nodes and create a dataset with it, then create the grids and assign to each one the differents filters of your dataset and on this way you will have one dataset with your xml and all the grids that you want by the filter that you select.

Here is how to read xml into a dataset

http://www.a1vbcode.com/snippet-2391.asp

Once you have the dataset, you can do this

Dim dTemp1, dTemp2, dTemp3 as New DataTable

With dataset1.Tables(0)
.DefaultView.RowFilter = "Type=1"
dTemp1 = .DefaultView.ToTable()
.DefaultView.RowFilter = "Type=2"
dTemp2 = .DefaultView.ToTable()
.DefaultView.RowFilter = "Type=3"
dTemp3 = .DefaultView.ToTable()
End With

grid1.DataSource = dTemp1
grid2.DataSource = dTemp2
grid3.DataSource = dTemp3

Hello,

I'm trying the code below, but getting error message "Can not find column "Type" ", any idea what I'm doing wrong?

Dim xmlPath1 As String
' ReaderOptions xml files
xmlPath1 = System.IO.Path.Combine(Application.StartupPath, "NSN.xml") 'grid1
'Populate dataset
dtsetcol1.ReadXml(xmlPath1)
Dim dTemp1, dTemp2, dTemp3 As New DataTable

With dtsetcol1.Tables(0)
.DefaultView.RowFilter = "Type=1"
dTemp1 = .DefaultView.ToTable()
.DefaultView.RowFilter = "Type=2"
dTemp2 = .DefaultView.ToTable()
.DefaultView.RowFilter = "Type=3"
dTemp3 = .DefaultView.ToTable()
End With

Grid1.DataSource = dTemp1
Grid2.DataSource = dTemp2
Grid3.DataSource = dTemp3

Thanks,

Victor

After reading the xml, check the Tables count. Set it as a datasource to a grid and see if the data is loaded correctly.

How do you check the Tables count? below is my xml file, could the format also be the problem?

<?xml version="1.0" standalone="yes"?>
<Root>
<Row>
<NSN_ID>0</NSN_ID>
<NSN>NA</NSN>
<Type>0</Type>
</Row>
<Row>
<NSN_ID>1</NSN_ID>
<NSN>1305-00-028-1111</NSN>
<Type>1</Type>
</Row>
<Row>
<NSN_ID>2</NSN_ID>
<NSN>1305-00-028-1112</NSN>
<Type>2</Type>
</Row>
<Row>
<NSN_ID>3</NSN_ID>
<NSN>1305-00-028-1113</NSN>
<Type>3</Type>
</Row>
<Row>
<NSN_ID>4</NSN_ID>
<NSN>1305-00-028-1114</NSN>
<Type>4</Type>
</Row>

<Row>
<NSN_ID>3</NSN_ID>
<NSN>1305-00-028-1115</NSN>
<Type>5</Type>
</Row>
<Row>
<NSN_ID>4</NSN_ID>
<NSN>1305-00-028-1116</NSN>
<Type>6</Type>
</Row>
</Root>

Did you try to set it as a data source to grid?

I'm using the following code for the grid, what should I be using?

Grid1.DataSource = dTemp1
Grid2.DataSource = dTemp2
Grid3.DataSource = dTemp3

Thanks,
