What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")

I have a list of servers, all exposing the same web service interface, that I need to call from my code.
i.e.
[URL]
My code needs to get this list of servers and invoke the same function on all of them.
I added a web references to this service, and I use "Dynamic" URL behavior. This is supposed to let me create an instance of the server proxy object, set the URI property at runtime, and then invoke the web methods, right?
But it seems the code generated by VS assumes the URI will come from the application's config file, which isn't the case for this app.
public SharpEyeWebService() {
this.Url = global::Company.DotNet.MyProject.Properties.Settings.Default.MyWebService;
if ((this.IsLocalFileSystemWebService(this.Url) == true)) {
this.UseDefaultCredentials = true;
this.useDefaultCredentialsSetExplicitly = false;
}
else {
this.useDefaultCredentialsSetExplicitly = true;
}
}
Is it safe to ignore the default URL the constructor uses and employ the approach I described above?

I'm using a listview control to show a list of categories/subcategories
<%# Eval("SubCategory1")%> When the user clicks the SubCategory1 link, the list view should fill up with the next subcategory, SubCategory2. The problem is off course that <%# Eval("SubCategory1")%> is hard-coded. I need it to change to <%# Eval("SubCategory2")%>...and so on, as the user is drilling down into the sub-categories.
So is there a way to change <%# Eval("SubCategory1")%> dynamically?

View 4 RepliesIn one of the interview, I was asked why should we have to go for Single Design pattern, instead of just creating static methods. Because creating static methods also serve the same purpose, i.;e avoiding flooding of objects.

I'm trying to do the following for asp.net combobox:
Text='<%# IIf(Eval("Name").ToString().Equals(""), Bind("Other"), Bind("Name") %>'
What I'm trying to do is if the "Name" column is empty then bind to "Other" column, otherwise bind to "Name" column. Anyone know the right syntax, keep getting object not set to reference. I'm doing this in VB.Net.
I tried binding a ListBox to an Object Data Source, but I can’t get the field to show up in the Data Source Configuration Wizzard for the ListBox. I got it working programatically populating the listbox using the DataReader but I’d like to be able to use the Object Data Source (Unless there are compelling reasons not to that I haven’t heard of yet.)

I can bind the data into a gridview. However, only the attributes are displayed(which is: category and ID). I need the elements to display out too (which is: Name,Description,Latitude and Longtitude).
Would anyone be kind enough to solve this problem for me?

View 1 RepliesI was just wondering if it is possible to bind data using DataBinder.Eval on a html tag with runat=server attribute. For example i want to do something like:

but it doesn't work. does this mean i have to use the asp.net hyperlink control?

I wanna use the DetailsView control without binding it with a datasource (just in insert mode) but the problem is when I try to get the values of the fields throught ItemInserting event handler I found the e.Values property empty however there are some fields.
Note: I wanna use it (The DetailsView control) [instead of allign the fields manually] because there're already a theme for it in whole the system and I don't want to do that again from scratch for custom template.
I have been led to believe that the best point to bind your controls is the PreRender. As all the controls are ready and this is the last stage before rendering etc. Is this correct or should controls be bound at a different point?
