I keep a label on the master page of my site that indicates when the site was last updated. I wanted to know if there was a quick and easy way to have the system update the date in the label everytime i compile the solution so the last updated field is always correct even if i happen to forget to update it manually.
View 3 RepliesI am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
I am using
public int deleteProduct(int ProductID, int rowid) {
// Create the Database object, using the default database service. The
// default database service is determined through configuration.
Database db = DatabaseFactory.CreateDatabase();
DataSet productsDataSet = new DataSet();

The above code am using but throwing below error how to resolve
"Update requires a valid UpdateCommand when passed DataRow collection with modified rows."

I am using an EntityDataSource with a FormView on VB.NET application. The FormView contains an AjaxControlToolKit TabContains with multiple tabs. Due to the fact that each tab is a naming container, Bind doesn't work properly for updating values (as discovered from reading other posts on stackoverflow). I instead have to declare UpdateParameters on my EntityDataSource. Example markup is as follows:
<asp:FormView ID="fv" runat="server" DataSourceID="eds" DataKeyNames="ID">
<EditItemTemplate>
<asp:TabContainer ID="tc" runat="server">
<asp:TabPanel ID="tp" runat="server" HeaderText="Tab 1">
[Code]....
This works great, until a customer is edited and their name is set to nothing (assuming in this case, a null name is allowed). The Name UpdateParameter is set to Null but the ObjectStateEntry is not set to modified for Null properties, even if previously the Entity had a value specified. As long as the name is changed to something other than Null, everything is updated correctly.
I found a workaround by putting the following code in the Updating event of the EntityDataSource.
Dim ose As ObjectStateEntry = context.ObjectStateManager.GetObjectStateEntry(action)
For Each p As Parameter In eds.UpdateParameters
ose.SetModifiedProperty(p.Name)
Next
This makes sure that each property in the UpdateParameters has its state set to modified. It works, but it seems like a hack and I can see it causing problems down the road. Is there anything else I could do?

I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:
$("#MyList_btnAddAll").click(function(e) {
e.preventDefault();
$('#MyList_lstAll option').appendTo('#MyList_lstSelected');
});
The code has two ListBoxes in fact, one a "source" and the other a "destination". As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected. These are rendered in the browser as <select> elements, as you'd expect.
The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback.
I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data? But in the codebehind after postback the ListBox contents haven't changed. Does anyone know what might be going on and what I can do about it?

View 1 RepliesThere is a field called school which is a dropdown menu, I manually edit items and made it like these: select school, name of 6 elementaries and 2 middle schools, and a high school.I have another field called grade level, which is a drop down menu too, i manually entered the grade items for it: select grade, Kindergarten, 1, 2, 3......12.
I would like after user selects a school in the drop down menu, the field called grade level dropdown box' data source will be updated according to school. For example, if it is a middle school selected, the data source of grade level will be updated to 6, 7 8 grade, if it is elementary the grade will be updated to 1, 2, 3, 4 5 etc. In this way later, when user goes to select grade it will show appropriate grade level lists according to schools.
I have a web page into which a user control is loaded. This user control contains a ListView. In the Page_Load event handler of the user control I have this code:
listView1.DataSource = TaskList; // Note: "TaskList" is a data table
listView1.DataBind();
It should be noted that the TaskList data table is actually instantiated in the web page. The user control then obtains a reference to it.
Everything described to this point works fine. Where I'm running into trouble is when I add a new row to TaskList. I had *thought* that the ListView control was dynamically connected to the data table, such that when I altered the contents of the data table in any way, that the changes would be automatically reflected in the ListView.
Since my content is embedded in my master page, if I place an update panel around my complete Master page controls including the content placeholders, are the content pages automatically included?

View 2 Replies<asp:Repeater ID="Repeater2" runat="server">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>
<asp:Button ID="Button2" runat="server" Text="Button" />
</ItemTemplate>

Lets say I have the above situation, and I need to update the appropriate label based upon which button is clicked. I have no idea how to do this. I can find a label via: (Label)Repeater2.Controls[0].Controls[0].FindControl("Label1");
But that only gives me the same label each time (so no matter which button I click the same lablel gets updated). How would I find the correct label to update?
I have an Asp.net page which requires certain sections to be partially updated automatically at an interval of 5 seconds. I was planning to use the good old Timer control with the AJAX Update Panel for this purpose, but after a bit of reading on this control i found out that it may have some problems especially if,
1) The time difference between the async event performed ( 4 seconds ) by the update panel and the Timer's tick interval ( which is 5 seconds ) are quite small, the update panel will be held up in the async operation all the time.
2) Also, the fact that timer control doesn't work very well with Firefox.
I just wanted to get your opinion as to whether if i should go ahead with the timer and update panel approach, write some custom javascript that does the partial page update or some other strategy altogether.
If I make a change to my database (let's say I add a column to a table), is there any magical buttons that I can click to have my Linq to SQL model update to reflect the changes to my table? I had to create two additional columns yesterday, and both times I found myself destroying and then recreating the Linq model.
View 2 RepliesI found some code on the web and it threw me off. Look at the code below. You will notice only when the Hits == 1, does the cache get added. After that, the cache object isn't updated. It begs the question, does the object when updated, update the cache as well automatically? The answer here would make me remove some code in some of my classes.
public static bool IsValid( ActionTypeEnum actionType )
{
HttpContext context = HttpContext.Current;
if( context.Request.Browser.Crawler ) return false;
string key = actionType.ToString() + context.Request.UserHostAddress;
var hit = (HitInfo)(context.Cache[key] ?? new HitInfo());
if( hit.Hits > (int)actionType ) return false;
else hit.Hits ++;
if( hit.Hits == 1 )
context.Cache.Add(key, hit, null, DateTime.Now.AddMinutes(DURATION),
System.Web.Caching.Cache.NoSlidingExpiration,
System.Web.Caching.CacheItemPriority.Normal, null);
return true;
}
I would only guess that I would need to add the lines after the if statement:
if( hit.Hits == 1 )
context.Cache.Add(key, hit, null, DateTime.Now.AddMinutes(10),
System.Web.Caching.Cache.NoSlidingExpiration,
System.Web.Caching.CacheItemPriority.Normal, null);
else if (hit.Hits > 1)
{context.Cache.Remove(key);
context.Cache.Add(key, hit, null, DateTime.Now.AddMinutes(10),
System.Web.Caching.Cache.NoSlidingExpiration,
System.Web.Caching.CacheItemPriority.Normal, null);
}
