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

ok, thank you, so I'll link id for each control so my c code, for example if I want to fill a select controle by a "select client from id_clt" I'll do it:
in DAL:public SqlDataReader selection (string agrecvt)
{
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "selectioncvt";
cmd.CommandType = CommandType.StoredProcedure;
using (SqlDataReader dr=cmd.ExecuteReader())
{
while (dr.Read())
{
agrecvt = Convert.ToString(dr["@agremcvt"]);
}
return dr ;
}
}
in BLL: public SqlDataReader selection(string agrecvt)
{
try
{
return cvtdal.selection (agrecvt );
}
catch
{
throw;
}
finally
{
cvtdal = null;
}
}
and in code interface:
protected void Page_Load(object sender, EventArgs e)
{
busniss_object.Classe_cvt cvt = new busniss_object.Classe_cvt();
Select4.DataSource = cvt.selection();
}
but it does'nt work if you can correct my code, thank you

I fill it with a DataTable like this...
DataTable Dt = new DataTable("Dt_Source");
Dt.Columns.Add("Id", System.Type.GetType("System.Int32"));
Dt.Columns.Add("Name", System.Type.GetType("System.String"));
Dt.Rows.Add(1, "Text1");
Dt.Rows.Add(2, "Text2");
Dt.Rows.Add(3, "Text3");
Dt.Rows.Add(4, "Text4");
Select1.DataSource = Dt;
Select1.DataTextField = "Name";
Select1.DataValueField = "Id";
Select1.DataBind();
good luck!

Dear all,
Im new in this and hope to get some advice.
I want to build a webservice that has to get some data as parameter from the client application. the data from the client side are records from there database.
my websercie has to send then these data to a soap server through 'HttpWebRequest'.
Can i get the data as Datatable? and then send as stream to the soap server?
Or maybe there is a better easier ways? your suggestion please
Thanks in advance.

A datatable is going to add a lot of overhead. I would suggest creating a class that represents the stuff you have in a row. That would then be a parameter of your web service. Those are known as "complex types" in the web services world. How you send it on after that depends on what is on the receiving end. Just saying it is SOAP doesn't give enough detail to say what kind of format it would accept. Are you doing anything with the data on the web server before you send it on? It seems like you are adding a middle man for no reason.

Hi T M Gray,
Thank you for reply!
By creating a class that represents the stuff in a row, the client app has to send then each record separately, so they have to call the webservice once for each record. Don't we have this way more overhead then sending the entire datatable at once?
And yes the webservice is acting as middle man between internet and the soap server for security reasons. the webservice has to send the data as string to that soap server.

Are you binding the dropdown in page_load event. If so is it within if(!Ispostback) ?
I think thats the problem you did not bind the dropdown within if(!Ispostback)
I think this may help u.............

Your problem could it be like sandympatil said! or maybe you're setting the same dropDownList1.DataValueField in the data source...
for example I have as source:
-column1----column2
---------------------
-red------------value1
-blue-----------value1
-orange-------value1
-black----------value1
and dropdownlist is
dropDownList1.DataTextField = "column1";
dropDownList1.DataValueField = "column2";
look out that. If that's so, the post back always select the first option with 'value1'... Ahh! I recommend you to use ajax CascaddingDropDownList Here!![^]

I tried the following but they won't work:
myDataGrid.DataSource = null;
myDataGrid.DataBind();

DropDownList1.Items.Clear();
|
|
|
|
