Adjust DataGridView's columns to fill available space if the grid is smaller and use scroll in case the grid bigger than the space available

问题

I want to adjust all columns of a DataGridView according to the required space to show all its data completely. If the space required is smaller than the available space i want the grid to fill this exceeding space, but if the available is space is not enough to display properly all columns i want to DataGridView create automatically a scroll. Is there an easy way to do this?

回答1:

Click over the DataGridView and select "Edit Columns...", then go to "Layout" and set "AutoSizeMode" to "Fill".

Hope this is what you're looking for.

Cheers

If you want to keep your table (DataGridView) formatted such that all of the columns are automatically sized, but one column in particular fills the remaining space, you can do something like this:

//Store the number of columns in a variable
int columnCount = dataGridView.Columns.Count;

//If we want the last column to fill the remaining space
int lastColumnIndex = columnCount - 1;

//Loop through each column and set the DataGridViewAutoSizeColumnMode
//In this case, if we will set the size of all columns automatically, but have
//the last column fill any extra space available.
foreach(DataGridViewColumn column in dataGridView.Columns) 
{
    if (column.Index == columnCount - lastColumnIndex) //Last column will fill extra space
    {
        column.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
    }
    else //Any other column will be sized based on the max content size
    {
        column.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    }
}

//Turn the scrollbars on for the DataGridView if needed
dataGridView.ScrollBars = ScrollBars.Both;

Go to DataGridView Property select "AutoSizeColumnsMode". Set "Fill".

DataGridView properties -> "AutoSizeMode" to "Fill" does fill up all the available space, however if a column is large enough to occupy majority of grid space, then rest of the columns size would shrink.

May be you can try "AutoSizeMode" to "AllCells". This not only fills up entire grid but also makes enough space to view all columns(with horizontal scroll bar)
