I have a datagridview with HTML strings. Using a CellDoubleClick event, I am displaying the html string in a WebBrowser control.
In Form1
private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
try
{
if (e.ColumnIndex != 0 && e.RowIndex != -1)
{
string s = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
this.f2 = new Form2(s);
f2.ShowDialog();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
In Form2
private IHTMLDocument2 doc;
string reply;
public Form2(string reply)
{
InitializeComponent();
this.reply = reply;
}
private void Form2_Load(object sender, EventArgs e)
{
webBrowser1.DocumentText = reply; <--- string from DataGridView
IHTMLTxtRange range = doc.selection.createRange() as IHTMLTxtRange;
range.pasteHTML(webBrowser1.DocumentText);
range.collapse(false);
range.select();
doc = webBrowser1.Document.DomDocument as IHTMLDocument2;
doc.designMode = "On";
}
Using the above code, I can successfully display the HTML string as a plaintext, however I am unable to edit it. Alternatively, if I use this code:
private IHTMLDocument2 doc;
private void Form2_Load(object sender, EventArgs e)
{
webBrowser1.DocumentText = reply; <--- string from DataGridView
doc = webBrowser1.Document.DomDocument as IHTMLDocument2;
doc.designMode = "On";
IHTMLTxtRange range = doc.selection.createRange() as IHTMLTxtRange;
range.pasteHTML(webBrowser1.DocumentText);
range.collapse(false);
range.select();
}
It will be a blank form, but I will be able to write to it.
I have a feeling it has to do with range.pasteHTML(webBrowser1.DocumentText); being in the Form2_Load method, but I'm unaware of any other method that will allow me to display the HTML string from the DataGridView upon opening Form2.
I want to allow users to be able to edit the HTML string as plaintext (after which it will be converted back to HTML and displayed in the datagridview).
