I linked some data to a datagridviewcomboboxcolumn via the designer , the problem is that when i display it, no default value is displayed, i want to display a default value for each cell, i tried with displaymember property of the DataGridViewComboBoxcell class in the constructor of the form, but i get an error. I dont know whats the property i have to change an in what eventhandler i must do it.
Thanks for your help!

You need to set the DataPropertyName property to the name of the field in your row.

Hope this helps.

i did what you say but, the problem still, i think datapropertyname doesn´t solve my problem. The combobox list all the values i want but the defaul value, is null, i must choose a value to change that. I just want to put the display default value manually. I think you get a better idea if i put an image but i cant.
Thanks!

i put an image in my avatar so i hope it can help you undestand my problem

Hi andresvite,

I am sorry to say DataGridViewComboBoxColumn doesn't offer default value property. Do you use data binding in your application?

If you use databinding, you can put a loop statement to set each datatable cell with a default value.

If you do not use databinding, you can put a loop to set each dataGridView cell with a default value.

Hope this helps you.
If you have any question, please feel free to tell me.

Sincerely,
Kira Qian
