first create a datatable

DataTable dt = new DataTable("TestDT");<br />
        dt.Columns.Add("ID");<br />
        dt.Columns.Add("NAME");<br />
        for(int n=1; n<3; n++)<br />
        {<br />
          DataRow dr = dt.NewRow();<br />
          dr["ID"] = n.ToString();<br />
          dr["NAME"] = n.ToString() + n.ToString();<br />
          dt.Rows.Add(dr);<br />
        }

then add datatable to Dataset

DataSet ds = new DataSet("TestDS");<br />
ds.Tables.Add(dt);

Create dataviewmanager
DataViewManager dvm = new DataViewManager(ds);
bind it to datagrid
dataGrid1.DataSource = dvm;

and finish

You can try something like this:

Javascript Code:

<script language="javascript" type="text/javascript">
function confirmdissociation ()
{
//alert("In Code");
if (confirm("Are you sure to perform this action?")==true)
{
document.getElementById("TextBox1").innerText ="true";
return true;
}
else
{
document.getElementById("TextBox1").innerText ="false";
return false;
}
}
</script>

In Code Behind:

private void Page_Load(object sender, System.EventArgs e)
{
Button1.Attributes.Add("onclick", "confirmdissociation();");
}

ObjectDataSource does not display valid BLL classes from BIN folder

Greetings!

I've got a slight problem with an ObjectDataSource i'd like to get your input on.

I've got an ASP.NET website created with two added references: A data access layer, and a buisness logic layer. The DLL's are both located in the BIN folder of the website.

The BLL classes are outfitted with the [System.ComponentModel.DataObject] and should be visible from the DataObjectSource's datasouce dropdown. However, they're not. I noticed something rather odd: I had only 1 page defined (default.aspx), and when i tried to define a data source for the ObjectDataSource, no classes were available what so ever. I then added a class to the "App_Code" folder and tried again. This time it cought on to all my TableAdapters and their underlying classes in the DAL.

It still refuses to include any of the BLL classes.

Can anyone shed light on the situation? Smile | :)

Thank you in advance.

Hi there,
Do you see the business classes listed in the combox if you uncheck the checkbox "Show only data components" in the Configuration DataSource dialog box?

If i check "show only data components" i get a list of the table adapters available from my DAL dll. If i uncheck it, i get a list of all the classes related to my defined DataSet (Table, Row, etc). But there is no sign of the BLL classes, even tho it exists as a reference in the "BIN" folder. It puzzles me.

I even tried to copy one of the classes from my BLL dll directly into the APP_CODE folder, but the ObjectDataSource still won't recognize it, no matter if i check or uncheck "show only.."

Thanks for your input!

Here's the culprit, the class needs to be declared as public.

, it's because of VS as it by default generates the class template with the default access modifier, and I guess you simply use it.

If u ask me there is no need to write in javascript. u just use the code behind.

if u still want to use javascript i think there is some way in the code behind file itself.

u can also include javascript just like u did for normal asp pages. using the <%%> and script tags.

i am not sure abt this. coz i have never used it.

Who's a clever boy then - that's quite a trick....how are you doing AJAX?

lavanya_satheesh wrote:

Kinda - Page.RegisterStartupScript allows you to code the js as text in the codebehind, then squirts it at the page

lavanya_satheesh wrote:

Except that <%%> will cause it to runat server.

To add some client side js, just add :

<br />
<script language="javascript" type="text/javascript"><br />
code goes here<br />
</script><br />

stringVariable = dataGridView.Rows[index].Cells[index].Value.toString();

stringVariable = dataGridView.Rows[index].Cells["ColumnName"].Value.toString();

stringVariable = dataGridView.CurrentRow.Cells[index].Value.toString();

in the data grid properties make the column as the template column and then add check box inside...

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
