Need help with hiding LinkButton in DataList

[News]

Hi,

I need help with datalist and linkbutton. I need a LinkButton to display in
datalist if datafield "is_measure_cus tomchecklist" in a db table set to
true.

Here is the code (in parts):

<asp:DataList id="dtl1"
runat="server"
DataKeyField="p rogram_id"
OnItemCommand=" DoItemSelect"
OnItemCreated=" Item_Created"
OnItemDataBound ="BindProgramGr id" >
<ItemTemplate >
<%# Container.DataI tem("name") %> &nbsp;
<asp:LinkButt on Visible="false" ID="managecheck list"
CommandName="ma nagechecklist" Text="Manage Checklist" CommandArgument ='<%#
DataBinder.Eval (Container.Data Item, "is_measure_cus tomchecklist") %>'
Runat="server" />
</ItemTemplate>

<SelectedItemTe mplate>
<b><%# Container.DataI tem("name") %></b> &nbsp; <asp:LinkButt on
CommandName="Ed itprogram" Text="Edit Program" runat="server" /> &nbsp;
<asp:LinkButt on ID="managecheck list" CommandName="ma nagechecklist"
Text="Manage Checklist" CommandArgument ='<%#
DataBinder.Eval (Container.Data Item, "is_measure_cus tomchecklist") %>'
Runat="server" />
.....
</SelectedItemTem plate>
1. I tried with this method but can not get commandargument (understand that
commandargument is not part of DataListItemEve ntArgs):

Sub Item_Created(se nder As Object, e As DataListItemEve ntArgs)
If e.Item.ItemType = ListItemType.It em Or e.Item.ItemType =
ListItemType.Al ternatingItem Then
' Retrieve the Label control in the current DataListItem.
Dim lbtnManageCheck ist As LinkButton =
CType(e.Item.Fi ndControl("mana gechecklist"), LinkButton)

lbtnManageCheck ist.visible = False
If lbtnManageCheck ist.CommandArgu ment.toString() Then
lbtnManageCheck ist.visible = True
End If

End If
End Sub
2. I tried another way, here I can get to command argument value but setting
of the link button to visible is not working:

Sub DoItemSelect(se nder As Object, e As DataListCommand EventArgs)

If e.Item.ItemType = ListItemType.It em Or e.Item.ItemType =
ListItemType.Al ternatingItem Then
' Retrieve the Label control in the current DataListItem.
Dim lbtnManageCheck ist As LinkButton =
CType(e.Item.Fi ndControl("mana gechecklist"), LinkButton)

lbtnManageCheck ist.visible = False
If lbtnManageCheck ist.CommandArgu ment.toString() Then
lbtnManageCheck ist.visible = True
End If

End If
End Sub


Can anyone advise what is the better way to get this thing working. I need
link button to appear in DataList on condition "is_measure_cus tomchecklist"
is true
Thank you...

In #2 you wrote:

If lbtnManageCheck ist.CommandArgu ment.toString() Then
lbtnManageCheck ist.visible = True
End If

try using:
If lbtnManageCheck ist.CommandArgu ment.toString() = "True" Then ....

the .toString() method will evaluate to Boolean True if is returns anything,
I believe you are looking for the text string "True" since you are using the
toString() to convert the CommandArgument contents to a text string...

Hope this helps! :)

Problem is, in the #2 it does not matter if it is True or "True" as I can
set the control visibility in that Sub, in the #2 method I can not get the
value of the CommandArgument which has the value of db field
"is_measure_cus tomchecklist". I can get this value in #1, where I can not
set the visiblity of the LinkButton...
