Windows Form Dynamic Controls Access ....

[sgavathe]

How would i access dynamically created windows form control.


I have Labels and TextBox generated dynamically from the database.

I want to create an XML from both controls.


something like

<Sample>
<Labes1.Textl > TextBox1.Text </Labels1.Text>
<Labes2.Textl > TextBox2.Text </Labels2.Text>
<Sample>

I am stuck in building the Loop while i am accessing form controls.

Have you tried XML Serialization?

Thanks for pointing out the serializer.

Nope, I haven't tried that.


The way i was trying to build XML was with string concatenation.


string Sample = "<Sample>";

sample += "<Label1.Te x>"

sample += "<Text1.Tex t>";

sample += "</Label1.Text>";


so it could build at the end like

<Sample>
<Labes1.Textl > TextBox1.Text </Labels1.Text>
<Labes2.Textl > TextBox2.Text </Labels2.Text>
<Sample>




This is how i was trying to do,

if (ctrl.GetType() == typeof(Label))
            {
                 
                string LabelText1 = ctrl.Text;
                teststring += "<" + LabelText1.ToString() + ">";

                // Ignore the control unless it's a text box.
                if (ctrl.GetType() == typeof(TextBox))
                {
             

                    string TextBoxText = ctrl.Text;
                    teststring += "<" + TextBoxText.ToString() + ">";
             

                }

                    teststring += "</" + LabelText1.ToString() + ">";   

            }

I am doing something wrong in the Loop.

There is also the System.Xml namespace. It has all kinds of handy XML utilities.

Thanks,

I don't see a loop in the above posted code....

I definitely recommend checking out XML Serialization.. .and also consider using StringBuilders instead of adding to strings...this saves on memory, time, and CPU resources.

Thanks for the help.

I am still not being able to get that working?

I am populating the form controls dynamically with label and texts, which is coming from another XML.

Then i am asking user to add value in the textbox and i want to build the XML again with those values in

<Label1> Text.value</Lable1>

Any help would be appreciated.


Thanks

I have got it working with string builder .... Thanks for pointing that out.

StringBuilder MyStringBuilder = new StringBuilder("<data>"); 
                     
                foreach (Control childControl in this.Controls)
                {
                    // Find a Particular Control by its Type
                    if (childControl.GetType().ToString() == "System.Windows.Forms.FlowLayoutPanel")
                    {
                        foreach (Control cc in childControl.Controls)
                        {

                            //ProcessControls(cc, xmlData);
                            if(cc is Control || cc is Label || cc is TextBox) 
                            {
                            
                            //if (cc is TextBox || cc is Label)
                            //{
                                if (cc is Label)
                                {
                                    string LabelText1 = cc.Text;
                                    //xmlData += "<" + LabelText1.ToString() + ">";

                                    MyStringBuilder.Append("<" + LabelText1.ToLower().ToString() + ">X</" + LabelText1.ToLower().ToString() + ">");
                                }

                                if (cc is TextBox)
                                {
                                    string TextBoxText = cc.Text;
                                    MyStringBuilder.Replace("X", TextBoxText.ToString());

                                }
                            
                            }


                        }
                        
                    }

                   
                }
                MyStringBuilder.Append("</data>");
