A question about Bind()

Question

User-36691632 posted

hey, guys

I am have a little problem in my aspx page with GridView control.

I have a bind like this:

<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="false" CommandName=""
       Text="Edit" PostBackUrl='<%# "FormEdit.aspx?RID=" + Bind("RuleID") %>'></asp:LinkButton>
</ItemTemplate>
And looks like it does not work. I am wondering how can I make it work. All I need is just to click it to FormEdit.aspx page with the RID as parameter.
Any inputs are welcome. Thanks.

if you're just posting to another page, i'd use a hyperlink instead of a linkbutton

Like this:

<asp:GridView ID="GridView1" runat="server">
  <Columns>
    <asp:HyperLinkField DataNavigateUrlFields="RuleID" 
                        DataNavigateUrlFormatString="FormEdit.aspx?RID={0}" 
                        Text="Edit" />
  </Columns>
</asp:GridView>

Hey,mbanavige

I got another similar question. For example:

<asp:BoundField HeaderText="Pair Type" DataField='<# Bind("RuleType")#>' />
Here, the rule type in database is the rule type id, I have a function to GetRuleTypeDescription(int nRuleType) to get the description for the rule type. So, actually, here, I want to do something like GetRuleTypeDescription((int)Bind("RuleType")), in asp.net 1.0, seems we can do similar stuff, but in 2.0, it won't compile.

Bind provides two-way binding to support editiing of the bound values.

When you are going to wrap the bound value in a function, you should use Eval (for one-way binding) instead of Bind.
So it would look more like this:

    GetRuleTypeDescription((int)Eval("RuleType"))
