Hello,

In a gridview, I am using a GridViewDecimalColumn to display numeric data.

The problem is that I would like to be able to use the two arrows key (Up and Down) to scroll on my GridView, and not have my data being increased or decreased when using them. Is there a way to disable the increasing and decreasing of data when using these keys ?

If not, is there a possibility to use another column type (GridViewTextBoxColumn for example) and then, how can I manage it so only numeric values can be typed into it ?

Thank you for your help.

Hello Bruno,

Thank you for writing.

You can have a column with only numeric values without using the GridViewDecimalColumn in two ways.
1. You could use a GridViewMaskBoxColumn with MaskType set to Numeric and Mask set to N0 (N zero).
2. You can use a GridViewTextBoxColumn and handle the KeyPress. Here is a code snippet which demonstrates how to do this:

private void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
  if (e.ColumnIndex == 0)
  {
    RadTextBoxEditor editor = e.ActiveEditor as RadTextBoxEditor;
    RadTextBoxElement element = editor.EditorElement as RadTextBoxElement;
 
    element.KeyPress += new KeyPressEventHandler(element_KeyPress);
  }
}
 
void element_KeyPress(object sender, KeyPressEventArgs e)
{
  if (!Char.IsNumber(e.KeyChar))
  {
    e.Handled = true;
  }
}

I hope this will help you. if you have further questions, I would be glad to help. Greetings,

Thank you for your answer.

Finally, I solved the problem by acceding to the SpinEditor of the column, and setting property InterceptArrowKeys to false.

Code sample :

GridSpinEditor spinEditor = this.radGridView.ActiveEditor as GridSpinEditor;
((RadSpinElement)spinEditor.EditorElement).InterceptArrowKeys = false;
