Can anyone teach me how to scroll news or data which is present in SQL Server Database on the web page using asp.net
Thanks in advance.

Well, the first thing to do is decide on a method to retrieve the data from the database. I would recommend stored procedure for that. Then you should create a data access layer to encapsulate the calls to the stored procedures. Once your retrieve the data, you can show it using a GridView control, a repeater or a DataList depending on your requirements. In a general view, that's all I can think of right now. Check for articles here on codeproject, I'm sure you will find some examples. If not, you will surely find something online. If you have more specific questions, you can post them here to discuss them.

ASP.NET can't do anything in scrolling. You can use some javascript or HTML marque to do scrolling. Get details from database and format it with the javascript you are using for scrolling. Set the string to a literal control. You are done.

what wil be the correspomding vb.net code for this:-
if(!Convert.IsDBNull(TxtBxMp .Value)
{
cmd.Parameters("@no_mp_record").Value = CType(TxtBxMp.Text, Int32);
}
|
|

|

Well, this is not valid code. It's missing a ), and CType is already nasty VB code, C# does not support it ( I just double checked ).
Replace the ! with Not, replace the {} with then and endif, remove the semicolon, and you're probably there.

hi
First of all C# doesnt support CType
VB code
If Not Convert.IsDBNull(TxtBxMp .Value) Then<br />
cmd.Parameters("@no_mp_record").Value = CType(TxtBxMp.Text, Int32)<br />
End If

ya , i also think so. but i had problem which i posted over here in response i got this soln. .
the problem is:
there are textboxes where i am entereing the int type value.here i am using sp to
save the value.if i am giving all the values in the textboxes the its working fine.but if i
am not giving all the values in the textbox means if i left some textbox with giving any value
.then its showing error as:" Message="Conversion from string " to type 'Integer' is not valid.".
where i have written the code as" cmd.Parameters.Add("@no_mp_record", Data.SqlDbType.Int)
cmd.Parameters("@no_mp_record").Value = CType(TxtBxMp.Text, Int32) "
and in the database i have defined its value as null and also in storeprocedure i have done accaordingly.
i have executed the sp seperately n its working.
why i am getting the error. or what will be solution for the error

TextBox.Text Return String If u pass nothing then it return String.Empty means "" and It can not convert "" to Int.Thats why u r getting this error.
Pass 0 if TextBox.Text=String.Empty Or Pass String Value to SP Instead Of Int.

Dear all,
I am using asp.net, C# , Sql Server 2005.
I am using datalist control and bind it like
<itemtemplate>
<asp:imagemap id="ImageMap3" imageurl="<%# DataBinder.Eval(Container.DataItem,"Photopath1") %>" runat="server">
<%# "Category : " + DataBinder.Eval(Container.DataItem,"Categoryid1") %>
<asp:imagemap id="ImageMap1" imageurl="<%# DataBinder.Eval(Container.DataItem,"Photopath1") %>" runat="server">
<%# "Category : " + DataBinder.Eval(Container.DataItem,"Categoryid2") %>
Here I am binding category and image path field.
Now these are static field I would like to know whether Is it possible to dynamically bind these field. That mean based on dataset filed can I be able to bind all the filed irrespective of its field defined
Thanks

Do you mean to dynamically find the fields and show whatever is there ? The GridView at least has an AutoPopulate property that will just show whatever is in the data source.

when you bind the dataset to the datalist control, ItemDataBound Event of the datalist control fires for each item in the datalist. In the Event you can find the control and assign the data item value to the control.

Other than the GridView that Christian has already recommended, I would also take a look at the Repeater Control[^].
It will repeat whatever HTML layout you want to use for each item in a list.

Hi all,
I'm pretty new to AJAX programming, and just started integrating the Microsoft Ajax toolkit etc. to VS2005. I followed the first sample and built a webpage containing a ScriptManager and an UpdatePanel, in which I've put a textbox and a button, and saw that AJAX worked fine to update this part of the page without the need to refresh the whole page.
But then I replaced my textbox / button controls with a self-made WebControl, which creates an HtmlTable in the CreateChildControls, containing rows and cells, and these cells contains linkbuttons with Events behind. This control was in the ContentTemplate of the UpdatePanel.
But when I click a linkbutton of my WebControl, the whole page gets postback and refreshed ... So my question is :
How can I build an AJAX enabled WebControl so it can behave like the standard textbox / button controls ? 
Do you guys know a good tutorial or book about that ?
Thanks !
Stéphane

It's worth mentioning that you do not need the AJAX toolkit, it's a framework designed to make AJAX happen automagically, but you get far greater control by writing your own code. If you choose to use the toolkit, make sure you always make clear you're using it, as your question is not an AJAX one, but a question on the MS AJAX toolkit.
A linkbutton in general creates a postback, I'm not sure how this relates back to textbox and button controls, or what exactly you're after ? you want the linkbuttons to use AJAX ?

Hi !
And thanks for answering me !
I'm sorry for my confusion between AJAX and MS AJAX ... Maybe they should have kept "Atlas" as the Framework name to avoid mistakes ...
In fact I'm not a Javascript fan, and never was ... The MS AJAX seemed to be a good solution for me, as it could give me the ability to use AJAX benefits without wondering about how it is implemented behind ...
My first try was to put in an UpdatePanel, a textbox and a button. In the eventhandler of the button, using C# code in the codebehind file, I put a statement like this :
<br />
protected void btnUpdate_Click(object sender, EventArgs e)<br />
{<br />
txtTest.Text = "This is a test";<br />
}<br />
At runtime, a click on the button generates a PostBack but the page doesn't move, only the textbox gets some text in it.
Then, to ensure a linkbutton can do that, I've added a link button in the same UpdatePanel. Here is the code :
<br />
protected void lkbAnotherTest_Click(object sender, EventArgs e)<br />
{<br />
txtTest.Text = "Link clicked";<br />
}<br />
The same : at runtime, the click on the linkbutton generates a postback but with the "AJAX behaviour", only the textbox got some text in it, the rest of the page didn't move.
But when I put a WebControl self made which is composed of a table with rows and cells themselves composed of many linkbuttons, at runtime, when I click on a linkbutton of my WebControl, the whole page gets refreshed ... I'm then wondering why ! And how I could get it work !

Sounds like you are trying to redirect at the wrong point in the page flow. What event are you trying to call Response.Redirect from?
