Hi
I am using Visual Studio with C# to develope a Web Application. I am using a DataList and binds it to a DataTable. When I run the application and the relevant page loads, the DataList is not displayed. I am using the following code:
private void Page_Load(object sender, System.EventArgs e)
{
string tableName = "Categories";
DataSet ds = categoriesDB.LoadCategories(tableName);
DataList_Categories.DataSource = ds.Tables[tableName];
DataList_Categories.DataBind();
}
The DataSet is holding data because when I bind it to a DataGrid on the same page to test it, the DataGrid displays the data correctly. What am I doing incorrectly or incompletely?
Thanks

Hi there. What does the ASP.NET markup of the datalist control look like? Also, you might want to check the Visible property of the control.

hi minhpc_bk
Thanks. I checked ASP.NET markup and I did not set up the ItemTemplate properly. It displays fine now. I am just struggling to get info out of the DataListItem when I have selected an item in the DataList.

DepLast = Convert.ToInt32(dt.Compute("SUM(essencbd_amount)","doc_date < '"+DateFormat.strYYYY+"/"+MM+"%' AND totalcode = '"+dsD.Tables[0].Rows[i][0]+"' ")) ;
i write this code but it give a error for this part"totalcode = '"+dsD.Tables[0].Rows[i][0]+"' ")) "
and that error massage is :
Cannot perform '=' operation on System.Decimal and System.String.

i am not sure but you can check it. normally the below statement returns a string and i think you are trying to add the returned string value to totalcode(probably a decimal).
dsD.Tables[0].Rows[i][0]
so you better to convert the same to decimal as shown below.
Convert.ToDecimal(dsD.Tables[0].Rows[i][0].ToString());
cheers.

You have to show the relevant code.
The = operator is not used in the code that you are showing, it's inside a string. The string is then fed to the dt.Compute method, so either you have to explain what that method does, or show the code for it.

This is horrible code. Consider refactoring it over several lines, that way you'll see the error more clearly and the compiler will be more helpful to you.

Hi,
I designed a menu with macromedia dreamweaver.It created a javascript and a file like *.js by it self.
I wanted to use this menu in my asp.net project therefore i copied the html codes and files from macromedia and pasted into my project.
When i run my asp.net project i can see the menu but the menu is not working properly.
It's colors must change when the mouse is on but not work.
How can i use macromedia projects in asp.net.
I want to include the macromedia codes in my project like this:
"<!--#include FILE="sol1.htm"-->"
how can i do it?
Thanks.

Are you sure you maintained the relative paths between the files correctly?

how to transfer data from a excel file into sql server's table.
Thanks in advance

first you must select a database and tables from enterprise manager which you want to insert excel table into.
then click the right button of the mouse and select import data.
The menu steps show you how to solve this problem.
|
|
|
|
|
but i can't use enterprise manager
i have to do that programatically in my asp.net application.
