Hello everyone.

How do I make a button edit accept numbers only? Is there any way you can do this? If possible give an example.

Hi Ulisses,

Thank you for contacting Syncfusion Support

To restrict the ButtonEdit to allow only numbers, you can handle the KeyPress event of TextBox element of ButtonEdit as shows in the following code example. 

 

//Invoke the KeyPress event 

this.buttonEdit1.TextBox.KeyPress += TextBox_KeyPress; 

 

private void TextBox_KeyPress(object sender, KeyPressEventArgs e) 

{ 

if (char.IsDigit(e.KeyChar)) 

{ 

e.Handled = false; 

} 

else 

{ 

e.Handled = true; 

MessageBox.Show("Allows Only Numbers "); 

} 

 

} 

 

We have prepared the sample for the same,you can download it from the following location:
