I know this is an old question but no one ever answered the first part, to set width in percent. That can easily be done with FillWeight (MSDN). In case anyone else searching comes across this answer.

You can set DataGridAutoSizeColumnMode to Fill in the designer. By default that gives each column FillWeight of 100. Then in code behind, on FormLoad event or after binding data to grid, you can simply:

gridName.Columns[0].FillWeight = 200;
gridName.Columns[1].FillWeight = 50;

And so on, for whatever proportional weight you want. If you want to do every single column with numbers that add up to 100, for a literal percent width, you can do that too.

It gives a nice full DataGrid where the headers use the whole space, even if the user resizes the window. Looks good on widescreen, 4:3, whatever.

or Simply you can go to the form and when you call the data to be displayed you set the property  like   datagridview1 columns 0  width   150  datagridview1 columns 1  width   150  datagridview1 columns 2  width   150enter code here  So simple worked so fine with me Bro

Most of the above solutions assume that the parent DateGridView has  AutoSizeMode not equal to Fill   If you set the  AutoSizeMode for the grid to be Fill  you need to set the AutoSizeMode for each column to be None if you want to fix a particular column width  and let the other columns Fill    I found a weird MS exception regarding a null object if you change a Column Width and the  AutoSizeMode is not None first   This works  chart AutoSizeMode    DataGridViewAutoSizeColumnMode Fill      add some columns here chart Column i  AutoSizeMode   DataGridViewAutoSizeColumnMode None  chart Column i  Width   60    This throws a null exception regarding some internal object regarding setting border thickness   chart AutoSizeMode    DataGridViewAutoSizeColumnMode Fill      add some columns here     chart Column i  AutoSizeMode   DataGridViewAutoSizeColumnMode None  chart Column i  Width   60

i suggest to give a width to all the grid s columns like this    DataGridViewTextBoxColumn col   new DataGridViewTextBoxColumn    col HeaderText    phone              col Width   120  col DataPropertyName    if you use a datasource  thegrid Columns Add col         and for the main or the longest  column let s say address  do this    col   new DataGridViewTextBoxColumn    col HeaderText    address   col Width   120    tricky part  col MinimumWidth   120  col AutoSizeMode   DataGridViewAutoSizeColumnMode Fill    tricky part  col DataPropertyName    same as above  thegrid Columns Add col     In this way  if you stretch the form  and the grid is  dock filled  in his container  the main column  in this case the address column  takes all the space available  but it never goes less than col MinimumWidth  so it s the only one that is resized   I use it  when i have a grid and its last column is used for display an image  like icon detail or icon delete    and it doesn t have the header and it has to be always the smallest one
