Question

I am trying to add the templateFields‘ values of my gridview into a List(Of String). Those templateFields consist of 2 Labels. What I am trying to achieve is

1. To be able to loop through every row of the GridView, getting the repetitive templateField values.

2. Store the row’s TemplateFields1 values in a string.

3. Add that string into a list of strings.

Here’s my code:

For Each row As GridViewRow In GridView1.Rows`
    Dim stri As String
    Dim ttt As Label = DirectCast(row.FindControl("Title"), Label)
    Dim desc As Label = DirectCast(row.FindControl("lblDescription"), Label)
    stri = ttt.Text.ToString & desc.Text.ToString
    Dim list As New List(Of String)
    While (stri <> Nothing) 
        list.Add(stri)  ' Add every new string in a new index of the list 
    End While
Next

So in the while loop, take stri store it in list(0) and then continue the for loop, get the next stri and store it in a new index of list(1) while keeping list(0) and so on until all templateField stri is completed.

Any thoughts or suggestions ?

Answer 1

You must create the list outside the loop. I’d also replace the While loop with an If statement:

Dim list As New List(Of String)

For Each row As GridViewRow In GridView1.Rows
    Dim ttt As Label = DirectCast(row.FindControl("Title"), Label)
    Dim desc As Label = DirectCast(row.FindControl("lblDescription"), Label)
    Dim stri As String = ttt.Text.ToString & desc.Text.ToString

    If (Not String.IsNullOrEmpty(stri)) 
        list.Add(stri)
    End If
Next
