Question

I want to populate a dropdownlist with comma seperated values from a textbox. I have below code:

sDDvalues = txtValues.Text

Me.DropDownList1.Items.Clear()
Dim months() As String = {sDDvalues}
Me.DropDownList1.DataSource = months
Me.DropDownList1.DataBind()

I have entered in the textbox like: value1, value2 and “value1”, “value2” and ‘value1′,’value2’, but every combination is returned as 1 option:

<option value="'value1', 'value2'">'value1', 'value2'</option>

Entering the actual values for months() like: {“value1”, “value2”} returns a correct dropdown:

<option value="value1">value1</option>
<option value="value2">value2</option>

Does anyone know how to solve this, so it populates from the values in the textbox?

Thanks in advance!

Answer 1

It should be:

Me.DropDownList1.DataSource = txtValues.Text.Split(New Char() {" "c, "-"c})

So completed:

Me.DropDownList1.Items.Clear()
Me.DropDownList1.DataSource = txtValues.Text.Split(New Char() {" "c, "-"c})
Me.DropDownList1.DataBind()

Input in the textbox would be like: value1 value2 value3

If you wanted to have it split at a comma then use:

Me.DropDownList1.DataSource = txtValues.Text.Split(",")

Input in the textbox would be like: this is my value1, this is my value2, this is my value3

Thanks for the responses!
