XML, C# Windows Forms and one heck of a headache

[datastreamcowboy]

Here's the deal I'm relatively new to C# and i got this windows form that i would like to use to edit the data in an XML file. I can use XMLRead and make a tree view that works.. but how do I get let's say the value in <owner> to show up in to the textbox so it can be entered if it is a new datafile or editited if its an old one.

I got the loading of the XML file working... tested it with the tree view.

<document>
<surface>
<owners>
<owner id="1">Sum dum guy</owner>
<address>1070 0 West Addison Chicago, Il</address>
</owners>
</surface>
</document>


the problem could also be in how I am trying to load the data into the textbox it's self. I tried to copy the node.value to string tOwner. and then use that variable later on down inthe code to be the text int he text box...

private void InitializeCompo nent()
{
.... stuff .....


this.textOwner. Location = new System.Drawing. Point(511,50);
this.textOwner. Name="textOwner ";
this.textOwner. Size = "new System.Drawing. Size(100, 20);
this.textOwner. TabIndex = 3;
this.textOwner. Text = txtOwner;


.... more stuff .....

}

ok.. found the problem.... kinda... i got a string to show in the field of the text box... ruled that one out...


is it better to put the XML file in to a string and read/write it usign XMLReader/XMLWriter or as a dataset?

[datastreamcowboy]

ok i have set up XmlReader

while (reader.Read())
{
     switch (reader.NodeType)
     {
          case XmlNodeType.Element:
               if (reader.Name == "owner")
               {
                     tOName = reader.Value;
               }

// ------ more code here

ok when i use reader.Name i get the variable to fill the text box with owner, but if i use reader.Value.. i get nothing..... <scratching head>

ok i got it fixed... i can read my XML document.... and fill in the form.. and here is how:

the xml document

<? xml>
<document>
   <surface>
      <detail state="TX" county="Johnson" description="See LTC." />
      <owners>
         <owner id="1" name="Sum Dum Guy" />
      </owners>
      <abs anumber="A-1314" />
      <tabs>
         <tab id="1" itype="mineral deed" fdate="03/04/2006" />
         <tab id="2" itype="warranty deed" fdate="03/01/2006" /> 
      </tabs>        
</document>

then here is how t fill out the form...

private void cmdLoad_Click(object sender, EventArgs e)
{
   XmlDocument document = new XmlDocument();
   document.Load(@"c:\sample-data.xml");          // replace with file name var.
   XmlNodeList owners = document.SelectNodes("/owners/owner");
   foreach (XmlElement owner in owners)
   {
      // fills in the tOwner textBox
      this.tOwner.Text = owner.GetAttribute("name"); 
   }

// Here is the tricky part we are going to gen the textboxes on the fly @ load
// call the onload method of the base class to ensure the Load
// event is raised correctly
   base.OnLoad(e);

// get number of rows
   XmlNodest tabs2 = document.SelectNodes("//tabs/tab");
   int x = 0;
   foreach (XmlElement tab2 in tabs2)
   {
      x++; // Row counter
   }

   // let's fill the arrays with data
   XmlNodeList tabs= document.SelectNodes("//tabs/tab");
   int c = 0;   // another counter
   string[] itypes = new string[x]; // create array for itypes
   string[] fdates = new string[x]; // create array for fdates

   foreach (XmlElement tab in tabs)
   {
      itypes[c] = tab.GetAttribute("itype");
      fdates[c] = tab.GetAttribute("fdate");
      c++;
   }

   this.SuspendLayout();

   int topPosition = 33;
   int zCounter = 0;
   while (xCounter < x)
   {
      TextBox TextBox = new TextBox();// Creates a new text box
      TextBox.Top = topPosition;           // Top Position of the row
      TextBox.Left = 11;                        // Left Side of the column
      TextBox.Text = itypes[zCounter];   // fills in from the array
      TextBox.Size = new System.Drawing.Size(98,22);  // TB Size

      // add it to panel
      panel1.Controls.add(TextBox);

     TextBox textFdateBox = new TextBox();
      textFdateBox.Top = topPosition;
      textFdateBox.Left = 115;
      textFdateBox.Text = fdates[zCounter];
      textFdateBox.Size = new System.Drawing.Size(100,22);
      // add it to panel
      panel1.Controls.add(textFdateBox);

      zCounter++;
      topPosition+= 24; // drop down for next row
   }
  // resume the the form's layout logic 
  this.ResumeLayout();
}
