Rtb @ C#

[RPG2KILL]

when i change text color at RTB by SelectionColor, i see the selection flickering.
how can prevent the RTB from updating view, until i finish coloring?

My question:
Is there another way to color text on rich text box, without using SelectionColor(,)?

Coloring text with SelectionColor() is not good enough, because its take too much time, and i see the text selected and unselected.
I have lot of text to color and it take many seconds till it finish.

you may try out,
richTextBox1.Focus();

richTextBox1.SelectionColor = Color.Red;

richTextBox1.SelectionFont = new Font ("Courier", 10, FontStyle.Bold);

try

{

int start = richTextBox1.SelectionStart;

int len = richTextBox1.SelectionLength;

System.Drawing.Font currentFont;

FontStyle fs;

for(int i = 0; i < len; ++i)

{

richTextBox1.Select(start + i, 1);

currentFont = richTextBox1.SelectionFont;

fs = currentFont.Style;

//add style

fs = fs | style;

richTextBox1.SelectionFont = new Font(

currentFont.FontFamily,

currentFont.Size,

fs

);

}

}



private void RemoveFontStyle(FontStyle style)

{

int start = richTextBox1.SelectionStart;

int len = richTextBox1.SelectionLength;

System.Drawing.Font currentFont;

FontStyle fs;

for(int i = 0; i < len; ++i)

{

richTextBox1.Select(start + i, 1);

currentFont = richTextBox1.SelectionFont;

fs = currentFont.Style;

//remove style

fs = fs & ~style;

richTextBox1.SelectionFont = new Font(

currentFont.FontFamily,

currentFont.Size,

fs

);

}

}



private void button1_Click(object sender, System.EventArgs e)

{

AddFontStyle(FontStyle.Bold);

}
