Why are you using 150 TextBoxes for 32 Elements?

Regardless of that there are thousands of examples of how to do data binding on t'interwebs. Use Google or Bing and search for c# databinding.

And all these elements must be shown to the user?? Maybe make use of a different control instead of TextBoxes...

Like the other member are saying ... it is very hard to help. We aren't exactly sure what you are trying to accomplish. You must try and explain your problem better.

Your question is not clear at all. Are the lengths of the table column 32 and the textbox 150 characters? Is the width of the text box 150px? (If so, you can restict the number of characters to 32 to help.

As for binding, try googling the phrase "c# textbox binding", you get lots of results.

The last time I looked, 32 * 6 wasn't 150. Why 150 textboxes (we ask again)?

This is far too many for the user to comprehend or fill in reliably in one go.
At the very least I suggest you create a wizard to enter each row at a time and ensure they add 32 rows somehow. Better yet, it sounds like an interface re-design might be appropiate.

As keefb says, that is way too many. Plus, what happens when suddenly you need to up it from 32 to 40 rows? Or add another column? Just what are you going to call these textboxes, that makes it easy to work out what is going on?

Think again. When did you see a database example that used textboxes for each row? What do database examples use?

Hi there,

I use a custom progressbar with text in a custom control and I update the text with a timer.The text is shown and everything works but the text over the progressbar mess up instead of being updated.When I minimize the main form and maximize it back, it updates. All of my attempts(using update(),refresh() and invalidate()) are useless.Could you please tell me what I should do?
note: I use the same control on another form but this time not in a custom control and it works like a charm

Is it possible to post some of the code?

//this code is in a custom control's class and the custom control is in main form

DateTime dt_starttime; //this takes the start time from a button on mainform when clicked
TimeSpan ts_elapsed;

public void tmrSure_Tick(object sender, EventArgs e) //this is triggered from the main form

// taking the elapsed time
DateTime dt_now = DateTime.Now;
ts_elapsed = dt_now.Subtract(dt_starttime);

theBestProgressBarEver1.CenterText = string.Format("{0:00}:{1:00}", ts_elapsed.Hours, ts_elapsed.Minutes); //CenterText is to show text

//normally the code is spreaded,I collected the pieces together to be able to post

Try setting the text within the progressbar with this piece of code: http://www.codeproject.com/Messages/3207094/Text-over-Progressbar[^], I think it will work!

thanks Programm3r
I solved the issue by putting ProgressBar.Refresh() on top in the timer event before the text property of the progressbar gets changed. But before, I had put it in the bottom of timer and didn't work. Anyway, thanks for dealing.

There is an article here on CP about serializing Dictionaries (amongst other things). Unfortunately, for you, it uses XML Serialization. In case it may offer you some clues, here is a link Yet Another XML Serialization Library for the .NET Framework[^]

Text over Progressbar - Question

Re: Text over Progressbar - Question

22-Sep-09 1:25

Hi all,

I found the following code, that allows one to write a string on a ProgressBar ... Only thing is that I can't get it to work Confused | :confused:

Can anyone else make it work, and if so ... what am I doing wrong?

// call the method
SetProgressBarText(progressBar1, null, ProgressBarTextLocation.Centered, Color.Black, SystemFonts.DefaultFont);

// Set the ProgressBar Text method
private void SetProgressBarText(System.Windows.Forms.ProgressBar Target,
    //The target progress bar
string Text,
    //The text to show in the progress bar
ProgressBarTextLocation Location,
    //Where the text is to be placed
System.Drawing.Color TextColor,
    //The color the text is to be drawn in
System.Drawing.Font TextFont
    //The font we use to draw the text
)
{
    //Make sure we didn't get a null progress bar
    if (Target == null)
        throw new ArgumentException("Null Target");

    //Now we can get to the real code
    //Check to see if we are to add in the percent
    if (string.IsNullOrEmpty(Text))
    {
        //We are to add in the percent meaning we got a null or empty Text
        //We give text a string value representing the percent
        int percent = (int)(((double)(Target.Value - Target.Minimum) / (double)(Target.Maximum - Target.Minimum)) * 100);
        Text = percent.ToString() + "%";
    }
    //Now we can add in the text
    //gr will be the graphics object we use to draw on Target
    using (Graphics gr = Target.CreateGraphics())
    {
        gr.DrawString(Text,
        TextFont,
            //The font we will draw it it (TextFont)
        new SolidBrush(TextColor),
            //The brush we will use to draw it
            //Where we will draw it
        new PointF(
            // X location (Center or Left)
        Location == ProgressBarTextLocation.Left ? 5 :
            //Left side
        progressBar1.Width / 2 - (gr.MeasureString(Text,
            //Centered
        TextFont).Width / 2.0F),
            // Y Location (This is the same regardless of Location)
        progressBar1.Height / 2 - (gr.MeasureString(Text,
        TextFont).Height / 2.0F)));
    }
}

public enum ProgressBarTextLocation
{
    Left,
    Centered
}

Many thanks in advance
