Hi,
I've made a menu manually by creating linkbuttons, each time i click on a button, i get the rest of the items in this way. the menu was created in a MASTERPAGE!
item 1 subitem11
item 2 subitem12
item 3 subitem13
item 4
and if i click on item 2 - what was before disappears and i get the subitems for item 2. and its working great.
anyway, when i click on any of the items, i change the color of this item, then i Response.Redirect it to the desired page. when i redirect it to the page it loses all of the proporties i have set to this specific linkbutton. Is there anyway i can save those proporties each time i redirect to another page?
here is the C# code i've made:
protected void LinkButton1_Click(object sender, EventArgs e)
{
this.LinkButton1.ForeColor = System.Drawing.Color.Red;
this.LinkButton2.ForeColor = System.Drawing.Color.DimGray;
this.LinkButton3.ForeColor = System.Drawing.Color.DimGray;

Why Link button ? Why not ASP.NET Menu ?

ASP menu is more flexible than Link Buttons!
but if you want to use LinkButtons, set it's style of selected in the page load event
|

Yeah a menu control could be just great, the only problem i couldnt design it the way i need it to be
like this :

Hello,
I´m a ex-programmer turned manager.
We will start development on a new ASP.NET web application and I wonder what are the best options for implementing membership services nowadays. We want to be able to support other databases other than MS SQL and the application should be hosted "on the cloud" or "on premises" depending on customer whim. Also, it would be great to be able to authenticate against AD and LDAP.
Microsoft membership? WCF Authentication, Role and provider services? My own custom machinations? Your custom machinations.
I just want some input so I can understand what my software architect says.
Thank you.

Hi,
My site is based on ASP.NET (C#) with sql server as the data source.
My Task:
Create a table based on the data source and when data is changed on the data source (sql server) update
the client table, but only update the cell with the data the was changed and not all the table – no page refresh.
Let’s say that checking for updates happens every 10 seconds.
There should be no data manipulation by the client such as insert/update/delete.
It’s something like a stock ticker that only updates data when it’s needed and only the data the was changed.
There’re lots of technologies out there: Ajax, Comet, jQuery, Linq etc.. and I’m getting lost with a task that shouldn’t be so complicated.
Comet requires a constant connection between the client & server and can be trouble when working with lots of clients.
What the right way to go?
Can you point me to a sample of such grid?
Thanks,
Assaf.

Given these requirements you will need to use Ajax to make an out of band call to retrieve the database info. From there JQuery will help, though it isn't necessary, with updating the DOM if necessary. That's it. There are plenty of examples on Using AJAX.

can you please point me to an example that do this?

How about here[^]?

google id full of examples but most of them are much more complicated in terms of user/client events and lack the part of DB changes that are being fetched by the client.
i'll appreciate an example.
Thanks,
Assaf.

Google is not going to provide you with a ready made solutions, neither are we. You have to learn to think for yourself.

Before you start to learn how
to do the updates you need something
to update.Have you already done something
similar to this ?
1. Create aspx page
2. Add to it a GridView
3. Fill a dataset from sql query
4. Set the GridView data source to the
dataset and bind
After this you can add methods to

the client table, but only update the cell with the data the was changed and not all the table
You can use updatepanel or XmlHttpRequest Object
or even an iframe to get the new data from server
without a page refresh.
Once you have this data you can then compare it to
existing data to find changes then update only the
cells whose data has changed.
Do you have any working code now ? If not follow the
steps i have laid out asking for help as needed.

Use an ajax update panel (UpdatePanel1) triggering a Timer Tick (Timer1) function which contains the UpdatePanel1.Update(); and that's all

i'm not new to asp.net. but it's my 1st steps in asp.net ajax.
updatepanel looks to me as the answer to my task, can you point me to an example?
Thanks,

If you're using Visual Studio 2008 or Visual Web Developer 2008, you can see the tools for Ajax Extensions or if is 2005, look here[^]
then add the timer and an update panel like...
<asp:Timer ID="Tmr_Update" runat="server" ontick="Tmr_Update_Tick">
</asp:Timer>
<asp:UpdatePanel ID="UpdPnl_UpdateEvery_5Sec" runat="server" UpdateMode="Conditional">
< ContentTemplate>
your content here
< /ContentTemplate>
< Triggers>
<asp:AsyncPostBackTrigger ControlID="Tmr_Update" EventName="Tick" />
< /Triggers>
< /asp:UpdatePanel>
You add a trigger and that means that the content template of the update panel will update every Tick event for the Tmr_Update Control...
you can Add the interval of the update like
Tmr_Update.Interval = 5;
Ahh don't forget the scriptManager before the tag
<asp:ScriptManager ID="SM_Detail" runat="server">
< /asp:ScriptManager>
Good luck

Thanks PunkIsNotDead,
your replt is very helpfull and it's the base for what i'm doing.
insted of "your content here" i'm using a datagrid that updates.
but the tricky part is that i want to be able to update only the certain cell data that was changed and not the whole grid.
also there could be n grids on my page and i can't know on advance how mant grid should be, also during running more grids can be added.
currently every "Tmr_Update_Tick" i'm doing a merge between the current datatable and the new one that i'm getting from the DB.
how can i do cell update, maybe even highlight it when there's a change?
also use n grids when n is known before runung?
my code right now shows one grid with the current data and one grid with only the changes:
.aspx
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:Timer ID="Tmr_Update" runat="server" ontick="Tmr_Update_Tick"/>
<asp:UpdatePanel ID="UpdPnl_UpdateEvery_5Sec" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="Server"></asp:GridView>
<br /><br /><br />
<asp:GridView ID="GridView2" runat="Server"></asp:GridView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Tmr_Update" EventName="Tick" />
</Triggers>
</asp:UpdatePanel>
.cs
protected string connStr = "xxxx";
protected DataTable dTable = new DataTable();
protected DataTable dTable1 = new DataTable();
protected void Page_Load(object sender, EventArgs e)
{
//On Load
Tmr_Update.Interval = 100000;//seconds
if (!IsPostBack)
{
GetDT(ref dTable);
BindGridView(ref dTable);
}
}
private void GetDT(ref DataTable myDT)
{
SqlConnection conn = new SqlConnection(connStr);
conn.Open();
SqlCommand objComm = new SqlCommand();
objComm.Connection = conn;
objComm.CommandType = CommandType.StoredProcedure;
objComm.CommandText = "someSP";
SqlDataAdapter dAd = new SqlDataAdapter(objComm);
dAd.Fill(myDT);
conn.Close();
}
private void BindGridView(ref DataTable myDT)
{
GridView1.DataSource = myDT;
GridView1.DataBind();
}
protected void Tmr_Update_Tick(object sender, EventArgs e)
{
//
GetDT(ref dTable1);
//dTable.Merge(dTable1);
DataTable d3 = new DataTable();// = dTable1.GetChanges();
d3.Merge(dTable);
d3.AcceptChanges();
d3.Merge(dTable1);
GridView1.DataSource = dTable1;
GridView1.DataBind();
GridView2.DataSource = d3.GetChanges();
GridView2.DataBind();
dTable = dTable1;
}
Thanks,
Assaf.

Hi! you could use jQuery highlight effect Here[^]. Is the first thing I think you can use in to Highlight a cell.
And try using a updatepanel in a
<asp:templatefield headertext="Prueba">
<itemtemplate><asp:updatepanel runat="server" id="UpdPnl_Test" updatemode="Conditional">
< ContentTemplate>
< div class="DivTest">< %#Eval("DataToUpdate")%>< /div>
< / ContentTemplate>
< Triggers>
< asp:AsyncPostBackTrigger ControlID="Tmr_Update" EventName="Tick" / >
< / Triggers>
< / asp:UpdatePanel>
< / ItemTemplate>
< / asp:TemplateField>
and on the timer.tick event you must compare the last data and the new. and performing the jQuery event in which divs satisfy the condition of "diferent than last time" or something like that.
 That would be hard men...
would be like < div... ...showHL='< %#Eval("UpdateThis")%>'> ...
and in the DataTable add a column with 'UpdateThis' to change (from false to true for example) in case that the last data changed too. And in script side you must select all divs that have changed every post back (or timer.tick)
$(document).ready(function(){
$('div[showHL="true"]')effect(
$("#effect").effect(selectedEffect,options,500,callback););
//callback function to bring a hidden div back
function callback(){
setTimeout(function(){ $('div[showHL="true"]').removeAttr('style').hide().fadeIn();
}, 1000);
});
note: jQuery function is not tested and i'm not sure of if it's sintax is ok too.

hello everyone,
I'm working on n-tier application and I want to use html controls, for example, instead of dropdownlist I'll use the select and instead of gridview I'll use a html table,
the problem that I could not fill them using sql query, and all the result of research on google there are php, if someone can help me in this level, thank you

Well, all ASP.NET controls render as html controls so I don't see what the issue is.
I know the language. I've read a book. - _Madmatt

This should be fine and there must not be an issue filling either one. Both expose similar properties to fill the values.
membre123 wrote: instead of gridview I'll use a html table,
This is tough! Though Gridview is rendered as table but the way values are defined for both, pagination, sorting, etc will be missing in Table... It cab be done with effort!...
What is the reason you are trying to convert them so? Ultimately ASP.NET controls are rendered as HTML only!
Further, what exact issue you are facing while filling them using SQL query - i dont find any reason you shouldn't be able to!

Hi! use in select and table like this...
<select id="yourAspSelectID" runat="server"></select>
<table id="yourAspTableID" runat="server"><tr><td>Content</td></tr></table>
And then you could reference it's id in code behind!
good luck
