sir my code contains many for loops for checking the datatable is this is the problem
|
|

It very well could be. You really should try not to query the database inside for loops. It can be a big performance killer.

sir its not a database its just a datatable sir
|
|

Sorry, kind of late here and eye are going Even with datatable you can still get a performance hit looping through it over and over. You aren't accessing the database at all with the datatable, what I mean is refreshing the datatable, hence still hitting up the database?

Sounds like you are making calls to the database. You might want to experiment with a gridview. Or minimize the amount of looping you need to do.

Well, it depends. If you ask the ASP.NET web developer like me, I will tell you to learn about ASP.NET 3.5, MVC or WCSF, LINQ and Silverlight. Those are the future of the web.

Each one has there own benifits and future.
Eace course has their won features.

hey can any one help me to create the pdf files from database table data in asp.net
|
|
|
|
|
You probably need to use some third-party library for creating pdf on the fly.
ASP.NET create pdf[^]
|
|
|
|
|
its better to transfer the necessary data into XML and translate it using .FO.
a third party tool like ibex can develop its PDF data from the .FO file

iam using dropdown list. The dropdown list items are assigned by datatable.now in this dropdown list some items should be hide to the user is it possible or not.
|
|
|
|
|
You should remove those items before binding with Dropdownlist. You can remove those unwanted items from either SQL query or remove from code.
|
|
|
|
|
You can remove the items which are not appropriate to display for corresponding users... while of course no need to write back to db, otherwise, you will remove them for good...

You can use Javascript timer or ASP.NET Ajax Timer control.

Hi Everyone,
I get the error:The name 'postComment' does not exist in the current context
groups.aspx.cs doesn't see what's in the groups.aspx. I can't use the option of putting the code inside the aspx together. I would like to know how to access the textbox from the aspx.cs page
I have two pages:
groups.aspx
groups.aspx.cs
I have created a button in the groups.aspx as follows:
<asp:textbox id="postComment" runat="server">
Now I want to access it from the groups.aspx.cs to insert the contents of what was entered in the text box to the database as follows:
protected void postBtn_Click(object sender, EventArgs e)
{
SqlDataSource PostDS = new SqlDataSource();
PostDS.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString();
PostDS.InsertCommandType = SqlDataSourceCommandType.Text;
PostDS.InsertCommand = "INSERT INTO GroupChalkboard (Text, GroupID, UserID, CreatedDate) VALUES (@Text, @GroupID, @UserID, @CreatedDate)";
PostDS.InsertParameters.Add("Text", postComment.Text);
PostDS.InsertParameters.Add("GroupID", pid.ToString());
PostDS.InsertParameters.Add("UserID", User.Identity.Name);
PostDS.InsertParameters.Add("CreatedDate", DateTime.Now.ToString());
PostDS.Insert();
}
Thank you.

Actually, those are not two pages. This is just one page and its code-behind file.
1. In Groups.aspx, the code file should be set to groups.aspx.cs.
CodeFile="groups.aspx.cs"
2. Check whether that textbox has runat="Server" or not.

The thing is that I have created the button and the textbox inside the Datalist, and because of that I can't access it directly. I don't know how to access it from the DataList. Here is the code:
I removed the open tags because it's not showing the code otherwise:
asp:datalist id="DataList1" runat="server" datasourceid="ChalkDL">
itemtemplate>
asp:textbox id="postComment" runat="server">
asp:button runat="server" onclick="postBtn_Click" id="postBtn" text="Post!" />
/itemtemplate>
/asp:datalist>

There are some events called Item_DataBound or Row_Created event. In those events, you can find the control..
For example:
TextBox txt = e.FindControl("controlname");

I just find a possible solution but for some reason I get an error:
System.Web.UI.WebControls.TextBox PostText = (System.Web.UI.WebControls.TextBox)DataList1.FindControl("postComment");
The name 'DataList1' does not exist in the current context
The data list was declared as:
asp:datalist id="DataList1" runat="server" datasourceid="ChalkDL">
And what's weird is that I can find DataList1 as an option in the properites and methods drop list when I start typing it.
What can be the reason for it?
