Hi,

I'm using the code below to display data from a DataGrid in a combobox:

 ComboBox2.DataSource = (From col As C1.Win.C1TrueDBGrid.C1DataColumn In C1Data.Columns Select col.Caption).ToList()
       

How do I modify the code to display data in the combobox only if the field name in C1Data exist in an xmlmfile?

For example if Main.xml contains the following data elements (NSC,FIF,AGD,UVN) in C1Data contains the following columns((NSC,FIF,NAS, PCS,NMN) I want the dropdown list to only contain (NSC,FIF)

Thanks,

Victor

Hi Fernando,

The XML format file is in the following format:

<Root>
<Fields>
<NSC></NSC>
<FIF></FIF>
<AGD></AGD>
<UVN></UVN>
</Fields
</Root>

Thanks,

victor

Hi Victor;

This should do what you are looking for.
'' Holds the node names of the XML document
Dim xmlTagNames As List(Of String)
'' Load the XML document
Dim xdoc As XDocument = XDocument.Load("Main.xml")
'' Get the names of the nodes
xmlTagNames = (From n In xdoc.Root.Element("Fields").Descendants()
               Select n.Name.LocalName).ToList()
'' Filter out the needed columns.
ComboBox2.DataSource = (From col As C1.Win.C1TrueDBGrid.C1DataColumn In C1Data.Columns
                        Where xmlTagNames.Contains(col.Caption)
                        Select col.Caption).ToList()

Hi Fernando,

It works. Thank You.

Is it possible to modify the code using multiple xml files? For example I want to load the combobox with values in the Grid matching fields in both Main.xml and Sub.xml. Other option is to create one xml file from Main and Sub.xml and use the existing code.

If necessary I can open a new issue.

Hi Victory;

I believe you would be better off using one XML file because you will then need to read in two or more XML files then query both and then combine the results into one list.
