I have a framepage(index.htm) which calls a 100% webform(one.aspx) which then contains two iframe webforms(a.aspx, b.aspx).
Now, in a.aspx, i have a treeview with checkboxes, next to each of the items. On check of each of these checkboxes, i pass the selected values to b.aspx, by using javascript and the top frame to pass values inbetween the pages.
For example, if the user checks on Name, Age and Gender in the treeview, i populate the same in b.aspx. Now i want to be able to let the user add conditions to these.
these conditions could be
Age : Greater than 20 and Less than 40
Gender : Male
Name : Contains Steve
But my problem is what is the best way to display Name, Age and Gender and populate a dropdown next to each of them and then based selection of each of these dropdown selected, one textbox or two textboxes should be displayed, depending on whether it is a range or a single value.
I am using a placeholder to generate columns, and row would have Age, Gender and Name, and a dropdown in the next column which would be contain the conditions. And then based on the condition, either one textbox would be made visible or two, depending on which condition is selected.
Now, i am facing this problem, as i have generated the dropdown which gets a feed from the dB, i can seem to access the individual textboxes in the placeholder.
my code is as follows:
PLACEHOLDER CODE
' Add Table Literal Control
litLabelfiller = New LiteralControl
litLabelfiller.Text = "<table border='0' width='100%' cellpadding='3' cellspacing='0'><tr><td align='left' valign='top'>"
phCondition.Controls.Add(litLabelfiller)
' Add TextBox Control
txtColumnP = New TextBox
txtColumnP.ID = "txtColumn" & strFieldNum
If Not FieldName = "" Then
txtColumnP.Text = FieldName
End If
txtColumnP.Width = Unit.Pixel(100)
txtColumnP.BorderWidth = Unit.Pixel(0)
phCondition.Controls.Add(txtColumnP)
' Add DropDownList Control
ddCondition = New DropDownList
ddCondition.ID = "ddCondition" & strFieldNum
ddCondition.AutoPostBack = True
AddHandler ddCondition.SelectedIndexChanged, AddressOf PopulateTextBoxes
populate_condition(ddCondition)
phCondition.Controls.Add(ddCondition)
' Add TextBox Control
txtRange1 = New TextBox
txtRange1.ID = "txtRange1" & strFieldNum
txtRange1.Visible = True
txtRange1.Width = Unit.Pixel(100)
phCondition.Controls.Add(txtRange1)
' Add TextBox Control
txtRange2 = New TextBox
txtRange2.ID = "txtRange2" & strFieldNum
txtRange2.Visible = True
txtRange2.Width = Unit.Pixel(100)
phCondition.Controls.Add(txtRange2)
' Add Closing Table Spacer Literal Control
litLabelfiller = New LiteralControl
litLabelfiller.Text = "</td></tr></table>"
phCondition.Controls.Add(litLabelfiller)
and the METHOD to access the dropdown, for example if the value of the dropdown is 8 or 9, then i need to make two textboxes visible as the condition would be a range rather than just one value.
Sub PopulateTextBoxes(ByVal sender As Object, ByVal e As EventArgs)
Try
Dim c As Control
Dim dd As DropDownList
Dim txt1 As TextBox
Dim txt2 As TextBox
For Each c In phCondition.Controls
If c.GetType Is GetType(DropDownList) Then
dd = CType(c, DropDownList)
Response.Write("Dropdown " & dd.SelectedItem.Value & "<br>")
If dd.SelectedItem.Value = 8 Or dd.SelectedItem.Value = 9 Then
Dim cName As String = CType(phCondition.FindControl("txtRange1"), TextBox).Text
' this is where i need to make the txtRange1 and txtRange2 textboxes are made visible
Else
' make only txtRange1 textboxes are made visible
End If
End If
Next
Catch ex As Exception
lberror.Text = ex.Message & "<br>" & ex.Source & "<br>" & ex.StackTrace
End Try
End Sub
any suggestions/advice is welcomed.
Thank you
