Hello,
I have a placeholder inside an update panel as showing in the below Code block.
I dynamically create some Comboboxes as showing below
I also have a submit button.
I want to get the selected value of the dropdownlist when the button is clicked.
I tried
but it didn't work. I also tried
but it didnt either work.
The controls of the Fields placeholder seems to be nothing in both approaches.
Could you please help me?
Thanks in advance,
Peny
I have a placeholder inside an update panel as showing in the below Code block.
<

asp:UpdatePanel
ID

"UpdatePanel36"
runat

.....
Dim
dropDownList
As
DropDownList
dropDownList =
New
DropDownList
dropDownList.ID = array_action_ids(i)
dropDownList.Visible =
True
dropDownList.DataSourceID =
"SqlDataSource2"
dropDownList.DataTextField =
"LEGAL_PHONE_NUMBER"
dropDownList.DataValueField =
"LEGAL_PHONE_ID"
Fields.Controls.Add(GetLiteral(
"<td>"
))
Fields.Controls.Add(dropDownList)
Fields.Controls.Add(GetLiteral(
"</td>"
))
.....
I also have a submit button.
I want to get the selected value of the dropdownlist when the button is clicked.
I tried
Dim
dropdownlist_phone
As
DropDownList =
CType
(Fields.FindControl(
"DropDownList_Phone"
), DropDownList)
but it didn't work. I also tried
Dim temp_Placeholder as Placeholder = CType
(UpdatePanel36
.FindControl(
"Fields
"
), Placeholder
)
Dim
dropdownlist_phone
As
DropDownList =
CType
(temp_Placeholder
.FindControl(
"DropDownList_Phone"
), DropDownList)
but it didnt either work.
The controls of the Fields placeholder seems to be nothing in both approaches.
Could you please help me?
