I explain my Project
Step:1
I created a Dynamic textbox.(eg:4)
Step:2
I saved data into xmlfile based on textbox.
Step:3
I retrieve from xmlfile based on textbox(on that save format).
I finished first 2 steps. my problem is 3 step.
Please Help me.
I send my code for u reference:

Declaration part
public static System.Windows.Forms.GroupBox gb;
public static string ModifiedPath = Path.GetDirectoryName(Application.ExecutablePath) + "\\Folder\\dataText";
Step:1
To create a groupbox and textbox:

gb = new GroupBox();
gb.Name = "GroupName";
gb.Text = "Virtual COM Port";
gb.Font = new System.Drawing.Font("Microsoft Sans Serif", 9F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
gb.Width = 300;
gb.Height = 150;
gb.Left = 10;
gb.Top = 15;
this.Controls.Add(gb);
int i;
for (i = 0; i < 4; i++)
   {
   TextBox txt = new TextBox();
   txt.Name = "Textbox" + i.ToString();
   txt.Text = "Testtext" + i.ToString();
   txt.Width = 150;
   txt.Height = 20;
   txt.Left = 100;
   txt.Top = 20 + (txt.Height * i) + (10 * i);

   gb.Controls.Add(txt);
   }

Step:2
To create a xmlfile and saved data from textbox.

string sFilename = xmlpath;
XmlDocument xmldoc = new XmlDocument();
XmlDeclaration xmldec = xmldoc.CreateXmlDeclaration("1.0", null, null);
xmldoc.AppendChild(xmldec);
XmlElement xmlele = xmldoc.CreateElement("Root");
xmldoc.AppendChild(xmlele);
for (int index = 0; index < 4; index++)
   {
   string targetTextBox = "Textbox" + index;
   //Try to find the textbox
   int textBoxIndex = gb.Controls.IndexOfKey(targetTextBox);
   if (textBoxIndex != -1)
      {
      TextBox foundTextBox = (TextBox)gb.Controls[textBoxIndex];
      Userprefrenece.txt1 = foundTextBox.Text;
      }
   String str = "port" + index.ToString();
   XmlElement port = xmldoc.CreateElement(str);
   xmlele.AppendChild(port);
   port.InnerText = Userprefrenece.txt1;
   }
xmldoc.Save(sFilename);
MessageBox.Show("Saved Successfully");

In my XML file data:

<?xml version="1.0"?>
<Root>
<port0>NARAYANAN</port0>
<port1>DELL</port1>
<port2>C#.NET</port2>
<port3>SUCCESS</port3>
</Root>

Step:3
??????(What will i do)
My output like this,

textbox1 =Port0 data
textbox2 =Port1 data
textbox3 =Port3 data
textbox4 =Port4 data

What is the problem?

Sergey Alexandrovich Kryukov 25-May-11 3:07am

You never explain what you want to do. As to Step 3, it looks like you want to read your mind.

Solution 1

I am not able to understand completely what you want in the third step.
If you want to read the xml and put it in those 4 textboxes , then here is how it goes:

C#

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(sFileName);
XmlElement rootElem = xmlDoc.DocumentElement; //Gets the root element, in your xml its "Root"

for (int i = 0; i < rootElem.ChildNodes.Count; i++)
{
    string name = rootElem.ChildNodes[i].Name;
    string value=rootElem.ChildNodes[i].Value;
    gb.Controls["Textbox" + (i + 1).ToString()].Text = name + " " + value;
}

Try now.

for (int i = 0; i < rootElem.ChildNodes.Count ; i++)
{
string name = rootElem.ChildNodes[i].Name;

Hi,
Thanks for help. I need another help.I have a Checkbox/Radio button in my form .I created Dynamically.
I have a 2 check box (created Dynamically).
One box is checked.Another one is unchecked.i saved data into XML.How can i get the value.Please clear my doubt.

Tarun.K.S 25-May-11 8:22am

What are the checkboxes for?

naraayanan 25-May-11 8:38am

Hi friends,
Step:1
I have a created Textbox,combo box and check box in my form(Dynamically).
Step:2
Insert values into XML like this structure.

<root>
<port0>COM5-Naraayanan-True</port0>
<port1>COM6-Mohan-False</port1>

Here ,COM5 is a Combobox value
Naraayanan is a textbox value
True is a Checkbox value(Checked).
But my Problem is when I read a XML. I got a result except Checkbox.Please tell me how to solve my Problem.
I give my readxml coding
gb is a Group Box in my form .
string sFilename = xmlpath;
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(sFilename);
XmlElement rootElem = xmlDoc.DocumentElement; //Gets the root element, in your xml its "Root"

for (int i = 0; i < rootElem.ChildNodes.Count ; i++)
{
string name = rootElem.ChildNodes[i].Name;
string value = rootElem.ChildNodes[i].InnerText;
string[] words = value.Split('-');
txt1 = words[0];
txt2 = words[1];
txt3 = words[2];

gb.Controls["Combobox" + (i + 0).ToString()].Text = txt1;
gb.Controls["Textbox" + (i + 0).ToString()].Text = txt2;
gb.Controls["RB" + (i + 0).ToString()].Text = txt3;

}
Last line is problem.Please How to solve my Problem?
Regards,
Lakshmi Narayanan

Lakshmi,
You can convert control type to Checkbox to solve your issue.

string sFilename = xmlpath;
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(sFilename);
XmlElement rootElem = xmlDoc.DocumentElement; //Gets the root element, in your xml its "Root"

for (int i = 0; i < rootElem.ChildNodes.Count ; i++)
{
string name = rootElem.ChildNodes[i].Name;
string value = rootElem.ChildNodes[i].InnerText;
string[] words = value.Split('-');
txt1 = words[0];
txt2 = words[1];
txt3 = words[2];

//I think "(i+0).ToString()" can be replaced by "i", When you let string type plus other types, they will automatically converted to the string type, this is a default mechanism in the c#.
gb.Controls["Combobox" + i].Text = txt1;
gb.Controls["Textbox" + i].Text = txt2;
(gb.Controls["RB" + i] as CheckBox).Checked = bool.Parse(txt3);
}

Solution 2

Hi Lakshmi,
I saw your issue, look my code below, it may be helpful.

string name, text, targetTextbox;
XmlDocument xml = new XmlDocument();
xml.Load(sFilename);
foreach (XmlElement item in xml.DocumentElement.ChildNodes)
{
    name = item.Name;
    text = item.InnerText;
    targetTextbox = name.Remove(0, 4);
    string targetTextBox = "Textbox" + index;
    //Try to find the textbox
    int textBoxIndex = gb.Controls.IndexOfKey(targetTextBox);
    if (textBoxIndex != -1)
    {
        TextBox foundTextBox = (TextBox)gb.Controls[textBoxIndex];
        foundTextBox.Text = text;
    }
}

What if Lakshmi renamed the textboxes? :rolleyes:

naraayanan 25-May-11 4:13am

Hi Xiaobei,
Thanks for help.I try it but it's not working . i send my code for u reference
string sFilename = xmlpath;
string name, text, targetTextbox;
XmlDocument xml = new XmlDocument();
xml.Load(sFilename);
for (int index = 0; index < 4; index++)
{
foreach (XmlElement item in xml.DocumentElement.ChildNodes)
{
name = item.Name;
text = item.InnerText;
targetTextbox = name.Remove(0, 4);
string targetTextBox = "Textbox" + index;
//Try to find the textbox
int textBoxIndex = gb.Controls.IndexOfKey(targetTextBox);
if (textBoxIndex != -1)
{
TextBox foundTextBox = (TextBox)gb.Controls[textBoxIndex];
foundTextBox.Text = text;
}
}
}

Please help me

Lakshmi,
Sorry for late.
Added "FOR" loop is not needed because I have used "Foreach" loop to loop through each node in the XML file.
I'm sorry for my mistake: I copy some code from you but i forget to change the name of the variable...
Look my code below:

string name, text, targetTextboxIndex;
XmlDocument xml = new XmlDocument();
xml.Load(sFilename);
foreach (XmlElement item in xml.DocumentElement.ChildNodes)
{
name = item.Name;
text = item.InnerText;
//Tarun's method is also good,simple and useful.
//But I think You can config a name mapping between XML node name and Textbox name to replace the HARDCODE.
targetTextboxIndex = name.Remove(0, 4);
string targetTextBox = "Textbox" + targetTextboxIndex;
gb.Controls[targetTextBox].Text = text;
}

Xiaobei

Xiaobei Zhang 25-May-11 21:24pm

Hi Tarun,
I think Lakshmi can create a config file to mapping XML node name and Textbox name to solve this issue.

Tarun.K.S 26-May-11 2:55am

Hmmm right, her XML is not well structured.
