I need to get selected items on checkbox and set as string format like (value1,value2,value3) from the checkbox i selected
For Each row As GridViewRow In GridView1.Rows
If row.RowType = DataControlRowType.DataRow Then
Dim CheckRow As CheckBox = (TryCast(row.Cells(1).FindControl("chckSelector"), CheckBox))
If CheckRow.Checked Then
Dim scode As String = TryCast(row.Cells(2).FindControl("lblsstorecode"), Label).Text
lbltest.Text = 'this i want to get the value like this (value1,value2,value3) from checkbox that i selected
End If
End If
Next
Depending on why you are using the GridView control, you might me able to accomplish this easier by using a CheckBoxList instead. In Asp.net what you describe is accomplished very easily with a CheckBoxList as follows:
In .aspx:
<asp:CheckBoxList ID="Itemlst" runat="server" RepeatColumns="1">
<asp:ListItem Value="">Item 1</asp:ListItem>
<asp:ListItem Value="">Item 2</asp:ListItem>
<asp:ListItem Value="">Item 3</asp:ListItem>
</asp:CheckBoxList>
</br>
<asp:Button ID="Button1" runat="server" Text="Button" />
</br>
<asp:TextBox ID="TextBox1" runat="server" Width="400"></asp:TextBox>
Then in the code behind:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim selected = New List(Of ListItem)
Dim itemcount As Integer
Dim csvlist As String = ""
For Each item As ListItem In Itemlst.Items
If item.Selected Then selected.Add(item)
Next
itemcount = selected.Count
For i = 0 To itemcount - 1
csvlist = csvlist & selected(i).ToString & ","
Next
csvlist = Mid(csvlist, 1, Len(csvlist) - 1)
TextBox1.Text = csvlist
End Sub
The Windows Forms CheckedListBox would probably work similar if you are developing a desktop application.
