Could you give me an example of what you mean?
Thanks!

Sure.
Here you are:
MyObjectType myObj = (MyObjectType)Session[myObjSessionIndex]

Okay, so something like this?
string strPartNum = (string)Session(what the heck would my index be? Don't I give it a name or something in parenthesis?)
Thanks again for your help!

your index is the name in of your variable.
Store object in session
Session[name] = object
Retrieve from session
object = Session[name].ToString()
name is any string variable
ex:
name= "myObjectSessionKey";

Okay, I don't think I'm doing this right. In my first .aspx.cs page I declared:
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
Session["ptNum"] = strPartNumberInputReference;<br />
if (Page.IsPostBack)<br />
{<br />
<br />
BindData();<br />
}<br />
}
In the second aspx.cs page I did:
Session["test"] = object;<br />
object = Session["test"].ToString();
But the compiler doesn't like object just hanging out like that. What am I missing?

What type is your object?
try
object = (myObjectType)Session["test"];

I placed the following in the second .aspx.cs page:
object = (string)Session["test"];
I get the error "identifier expected"

Can you send code snippet, please?

No problem! Here is page one aspx.cs:
protected string strPartNumberInputReference;<br />
.<br />
.<br />
.<br />
<br />
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
Session["ptNum"] = strPartNumberInputReference;<br />
if (Page.IsPostBack)<br />
{<br />
<br />
BindData();<br />
}<br />
}
Page 2 code behind:
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
object = (string)Session["ptNum"];<br />
if (!Page.IsPostBack)<br />
{<br />
<br />
BindData2();<br />
test2 = txtTest.Text; <br />
}<br />
}
|
|
|
|
|
On which line the compiler complains?
Have you declared/initialized object variable?
But first check, that it is not a keyword?

Now the session variable is giving me a different problem
Basically what I'm trying to do: On the first page user enters a partnumber and the datagrid populates based on that partnumber. User goes to second page, second page already recognizes part number and populates a new grid based on that partnumber.
The BindData function for the first page works fine:
private void BindData()<br />
{<br />
strPartNumberInputReference = txtPartNumberInput.Text;<br />
<br />
<br />
string SQLString = "SELECT w.weight, wt.Description AS wtDescription, p.PartNumber from weights w INNER JOIN weighttypes wt on wt.ID = w.weighttypeid INNER JOIN Parts p on w.PartID = p.ID WHERE p.PartNumber = @PartID"; <br />
SqlCommand cmd = new SqlCommand();<br />
cmd.Connection = new SqlConnection(strConnectSQL);<br />
cmd.CommandText = SQLString;<br />
cmd.Parameters.Add ("@PartID", strPartNumberInputReference);<br />
SqlDataAdapter adapter = new SqlDataAdapter(cmd);<br />
adapter.Fill(ds);<br />
<br />
dgParts.DataSource = ds;<br />
dgParts.DataBind();<br />
<br />
<br />
}
Page Load where session variable is:
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
Session["ptNum"] = strPartNumberInputReference;<br />
if (Page.IsPostBack)<br />
{<br />
<br />
BindData();<br />
}<br />
}
So on the second page I have:
public string test2;<br />
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
test2 = (string)Session["ptNum"];<br />
if (!Page.IsPostBack)<br />
{<br />
<br />
BindData2();<br />
; <br />
}<br />
}<br />
<br />
private void BindData2()<br />
{ <br />
string SQLString = "SELECT w.weight, wt.Description AS wtDescription, p.PartNumber from weights w INNER JOIN weighttypes wt on wt.ID = w.weighttypeid INNER JOIN Parts p on w.PartID = p.ID WHERE p.PartNumber = @PartID";<br />
SqlCommand cmd = new SqlCommand();<br />
cmd.Connection = new SqlConnection(strConnectSQL);<br />
cmd.CommandText = SQLString;<br />
cmd.Parameters.Add ("@PartID", test2);<br />
SqlDataAdapter adapter = new SqlDataAdapter(cmd);<br />
adapter.Fill(ds2); <br />
ds2.Tables[0].TableName = "Weights";<br />
dgWeights.DataSource = ds2;<br />
dgWeights.DataBind();<br />
<br />
}
But I'm getting the error:Prepared statement '(@PartID nvarchar(4000))SELECT w.weight, wt.Description AS wtDes' expects parameter @PartID, which was not supplied
I'm trying to pass the test2 as the parameter which should be the strInputNumberReference from page 1.
So I think I still have something incorrect.
Again, thank you SOOO much for helping me with this!

You are welcome.
Check with the debugger, where exactly you fall down.
Unfortunatelly, I have to do my staff now.
Can not figure out the problem straight.
Just one thing: shouldn't you specify command type? Text/SP

One more note
"object" is a keyword, if I remember it correctly

Well, actually not a string, but an object.

Hi all,
I'm trying to save changes made to a web parts page to the db, I can add the webparts programatically but they disappear on the first postback. I've read about extending the WebPartManager class to use the SetPersonalizationDirty() function, but as I'm still fairly new to using WebParts I'm not sure how to do this.
Basically what I would like to know is how to gain access to the class itself to write an override function, or whether or not I can put the function in the existing code.
Thanks in advance for any help or suggestions, Cheers.
A humble novice,
Lil Turtle

Hi there,
Because the SetPersionalizationDirty is defined as below:
protected void SetPersonalizationDirty () So you cannot override this method, what you may do is to inherit from this class, and define a new public method which in turn calls the protected method SetPersionalizationDirty. The sample code looks something like;
public class MyWebPartManager : WebPartManager
{
public void ExSetPersonalizationDirty()
{
SetPersonalizationDirty();
}
}
|

Thanks for the reply, and the info. I implemented the changes you suggested and the code runs wonderfully.
Thanks again.

I created a drop downlist dynamically and i am unable to capture its values i.e its view state.
I know that view state can't be retained for dynamically created controls .pls suggest a way out to retain the view state.
|
|
|
|
|
Actually, the dynamic control can persist data in the ViewState as the static control does. The important thing when working with the dynamic control is that you need to choose the right event to readd the dynamic controls. If this happens after the ViewState is loaded, then it will loose its ViewState data. For more information, you should read about the control life cycle in MSDN.

if you want to see the selected value each time, it is easy...
give it an ID, say idListBox.
while creating it, get the value from form variables to determine the selected value:
...
selVal = request.forms("idListBox")
loop
create a list item
if value of the item = selVal then add "selected" to the item
add item
end loop
...
That's it...

hi all
i have a string in dd/mm/yyyy (e.g 26/06/2006) i wants to insert in database as datetime format. the data type in database is DataTime.
pls send the syntex.
thankX

First parse the string into a DateTime value:
DateTime theDate = DateTime.ParseExact(theString, "dd/MM/yyyy", CultureInfo.InvariantCulture);
Then you can use the DateTime value in the call to the database.
