How to resize the column widths proportionately when the grid is resized in the virtual grid in WinForms Grid Control?
Resize the column widths
Step
1: Using the
built-in property
Set the AllowProportionalColumnSizing to True to auto-resize the columns when the grid is resized.
//Enable auto resizing the columns when Grid is resized.
this.gridControl1.AllowProportionalColumnSizing = true;'Enable auto resizing the columns when Grid is resized.
Me.gridControl1.AllowProportionalColumnSizing = TrueStep
2: Using
workaround
To auto-size
the columns, you can use the grid.ColWidths.ResieToFit and create
an array of doubles. For example, in this array, colRatios computes the ratio
of each column width to the grid.ClientSize.Width.
This gives the proper proportion value for each column. Then you can subscribe to the grid.QueryColWidth and provide the size of the column widths by multiplying this ratio by the grid's width. Set e. Handled = true. You can refer to the following codes.
double gridwidth = this.gridControl1.ClientSize.Width;
for (int i = 1; i <= this.gridControl1.Model.ColCount; i++)
{
colRatios[i - 1] = (double)(this.gridControl1.Model.ColWidths[i] / gridwidth);
}
…
void gridControl1_QueryColWidth(object sender, GridRowColSizeEventArgs e)
{
e.Size = (int)(colRatios[e.Index ] * this.gridControl1.ClientSize.Width); e.Handled = true;
}Dim gridwidth As Double = Me.gridControl1.ClientSize.Width
For i As Integer = 1 To Me.gridControl1.Model.ColCount
colRatios(i - 1) = CDbl(Me.gridControl1.Model.ColWidths(i) / gridwidth)
Next i
…
Private Sub gridControl1_QueryColWidth(ByVal sender As Object, ByVal e As GridRowColSizeEventArgs)
e.Size = CInt(Fix(colRatios(e.Index) * Me.gridControl1.ClientSize.Width))
e.Handled = True
