I am currently working on VB.net

I want delete rows from tablelayoutpanel while i select the checkbox.

When i am checked checkbox at a time rows should be deleted from tablelayoutpanel by using vb.net

What I have tried:

Private Sub Button5_Click(sender As Object, e As EventArgs) Handles Button5.Click

Dim row As Integer
row = TableLayoutPanel1.RowCount - 1
For col As Int32 = 0 To 6
Dim c As Control
c = TableLayoutPanel1.GetControlFromPosition(col, row)
TableLayoutPanel1.Controls.Remove(c)
Next
TableLayoutPanel1.RowStyles.RemoveAt(row)
TableLayoutPanel1.RowCount -= 1

End Sub

In this code, row will delete but from last.

Actually i want to delete row which is selected by user.

It appears you have set the row to be deleted as the last row in your code above

This line is the problem

VB

row = TableLayoutPanel1.RowCount - 1

Steps you should follow:

a. Loop through all Controls in TableLayoutPanel1
b. Find checkbox and see if it is checked
c. Get its position (row and Column) using GetPositionFromControl
d. Get the row
e. Delete the control
f. Delete the row

VB

DIM RowToDelete as Integer
For Each CNTRL in TableLayoutPane1.Controls
If (TypeOf CNTRL Is CheckBox) AndAlso DirectCast(CNTRL, CheckBox).Checked Then
		RowToDelete = TableLayoutPanel1.GetPositionFromControl(CNTRL).Row
		TableLayoutPanel1.Controls.Remove(CNTRL)
		Exit For
End If
Next

TableLayoutPanel1.RowStyles.RemoveAt(RowToDelete)
TableLayoutPanel1.RowCount -= 1

Hope this helps.
