Hi Steve,
Thanks for your post!
Yes, DataGridView.RowTemplate property is used for the default row template
of new created rows. So if you change the DataGridView.RowTemplate property
before the DataGridView is bound, DataGridView will use this modified value
to display the rows. However, if you change this property after the all the
rows are created, its modification will not reflect on existing rows. If
you add a new row into the DataGridView, the new row will reflect this new
DataGridView.RowTemplate value.
Below is the sample code demonstrates my statement:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Me.DataGridView1.RowTemplate.Height =
Me.DataGridView1.RowTemplate.Height + 10
Dim dr As DataRow
dr = dt.NewRow()
dr("column1") = 100
dr("column2") = "item100"
dt.Rows.Add(dr)
End Sub
Dim dt As New DataTable
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
dt.Columns.Add("column1", GetType(Integer))
dt.Columns.Add("column2", GetType(String))
Dim i As Integer
Dim dr As DataRow
For i = 0 To 5
dr = dt.NewRow()
dr("column1") = i
dr("column2") = "item" + i.ToString()
dt.Rows.Add(dr)
Next
Me.DataGridView1.DataSource = dt
End Sub
End Class
If you click the Button1, the new added row will be 10 pixel heigher than
original rows.
To change the existing rows height, you should enumerate through the
DataGridView.Rows collection to get each DataGridViewRow reference and
change its Height property. The code snippet below demonstrate this:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button2.Click
Dim i As Integer
Dim dgvr As DataGridViewRow
For i = 0 To Me.DataGridView1.Rows.Count - 1
dgvr = Me.DataGridView1.Rows(i)
dgvr.Height = dgvr.Height + 10
Next
End Sub
Hope this helps!
