How to display the value of a NumericUpDown Cell in Hex, Dec, Oct and Bin formats?

[Dongxian Li]

Hi,
I have a gridControl that has a NumericUpDown cell, I need to show the value in Hex format(0x1d2c), Decimal format(234), Octal format(343) or binary format(010101) according to user preference, how can I do this?

Thanks

You will have to derive a cell control to manage this. I do not have a sample for this, but here is a link to derived cell numericupdown that supports decimal increments. http://www.syncfusion.com/support/user/uploads/fractionnumericupdown.zip

This shows how you can tweak the behavior using s derived numericupdown celltype.

Hi,

I used this model and it works fine. But the problem is we can''t type in decimal values into this control (up down button works fine but user sometimes may overtype a decimal number in), is that anyway we can support this as well?

Million thx!

Hi Eric,

Could you try this code to accept the decimal Keystrokes in a FractionNumericUpDown Cell. Here is a code snippet

//in FNumericUpDownCellRenderer class
protected override void OnKeyPress(System.Windows.Forms.KeyPressEventArgs e)
{
base.OnKeyPress(e);
//digits only in column2
if(!char.IsDigit(e.KeyChar))
{
if( e.KeyChar != ''.'' )
e.Handled = true;
}
}

Here is a modified sample.

Let me know if this helps.
