  I have 100 textboxes in the group header section of the report returned from the data reader and would like to check if the text box has value or not. I would like to display “-” on the textbox does not have any value displayed. Please help.

  Hi Josie,

  You can handle the ‘GroupHeader_Format’ event to get the Text property of your TextBox(es). In the handler, you can check if the value is equal to an empty string you can then assign ‘-’ to your TextBox.

  Please find attached a sample implementing the same.

  thanks for providing the sample code. My case is a little bit different. I have over 20 text boxes in the group header section and will be tedious to check all of them like this for 20 text boxes. I would like to create a function that I can use for another report too if possible.
  
  if (this.textBox1.Text == “”)
  
  this.textBox1.Text = “-”;

  I was hoping to write a for each loop and check if the control is a textbox; if it is empty, then apply “-” for those textboxes with no value.

  Hi Josie,

  In case you are having multiple TextBoxes you can use a foreach loop to iterate over all of the controls in your GroupHeader to check if they are a TextBox with a text of “” if yes you can replace it with “-”.

  Please find attached the updated sample for the same.
