Hi,
i am using a charting component to generate graphs for which data is dynamically gets bind from db
In my page there is an image creation button is there, if a user clicks on that an image download dialogue will be displayed
The code i am using for it is
MemoryStream mstream = new MemoryStream();
try
{
Chart1.Save(mstream, ChartImageFormat.Png);
byte[] byteArray = mstream.ToArray();
Response.AddHeader("Content-Disposition", "attachment; filename=report.png");
Response.AddHeader("Content-Length", byteArray.Length.ToString());
Response.ContentType = "image/png";
Response.BinaryWrite(byteArray);
}
catch
{ }
finally
{
mstream.Flush();
mstream.Close();
}
The image downloading works fine, but after image download if i rebind the report again from db the page is taking too long to load, some times page loads partially,some times page gives some xml error, which i will work fine if i dont click image generating button only binds the report.
In my local system this works fine, but in staging server(IIS 6.0) it is giving the above problem

Hi,
now it is working fine,
i just put Response.End() after Response.BinaryWrite(byteArray);
and it is working,although i dont know the exact reason why

hello,
i have a strange phenomenon which happens only at the remote site.
it doesnt happen in my local machine.
i noticed that the PageInit is called twice in the master page.
i know that because i trapped there an Exception that writes to a file
the information of the Exception.
the file was written twice with the delay of approx 300 msec between them.
(i use a tick counter to construct the file name)
in the local machine the file is written only once.
does anyone have an idea why this happens ?
tnx,
avi

Well, do you know that you can also debug a remot site from VS?

mm.. interesting.
i put a trap for all the events and all of them loaded only once.
(pageload, pageinit)
the twice load happened only when there was an exception.
the exception was called twice.
is there a retry or something?
|
|
|
|
|
Is the Page_Load event also called twice?
If so, look into this link[^]

Hi all,
I have view of some example (globalization) to develop a multilingua web site. But still cant success on it.i have create a .resx file call rsc.zh-CHS.resx in floder App_GlobalResources. Then using the the code following to display selected language. And also use a dropdownlist to select a preferral language
private ResourceManager rm;
protected void Page_Load(object sender, EventArgs e)
{
CultureInfo ci;
if (!IsPostBack)
{
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
rm = new ResourceManager("rsc", Assembly.Load("App_GlobalResources"));
ci = Thread.CurrentThread.CurrentCulture;
LoadData(ci);
}
else
{
rm = new ResourceManager("rsc",Assembly.Load("App_GlobalResources"));
ci = Thread.CurrentThread.CurrentCulture;
LoadData(ci);
}
}
public void LoadData(CultureInfo ci)
{
lblCNName.Text = rm.GetString("lblCNName", ci);
lblENName.Text = rm.GetString("lblENName", ci);
}
I get a error in LoadData() and said that:
Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "rsc.resources" was correctly embedded or linked into assembly "App_GlobalResources.qb8c2ydr" at compile time, or that all the satellite assemblies required are loadable and fully signed.
Note: my example come from http://ashrafur.wordpress.com/2008/01/17/multi-language-supported-web-site-in-aspnet/[^]
any tips are welcome.

If you are just displaying data in the UI , I would recommend a repeater. it is much lighter.
As for deleting 0 values simply add a constraint to your where clause in the proc where you are retrieving data.
|
|
|
|

Here is a code might help you. I think you are using MSSQL server 2005.
SqlConnection cnnew SqlConnection(...your_connection_string....);
SqlCommand cmd=new SqlCommand();
cmd.Connection=cn;
cmd.CommandText="your_proc";
cmd.CommandType=CommandType.StoredProcedure;
...
...
SqlDataAdapter adp=new SqlDataAdapter(cmd);
DataTable dt=new DataTable();
adp.Fill(dt);
GridView v=new GridView();
v.DataSource=dt;
v.DataBind();
form1.Controls.Add(v);
..

logic 1:
When you fetch the values from the table, write query like this
select case empty_column when 0 then '' from table_name
where <condition>
logic 2:
If you use gridview, in GridView1_RowDataBound event you can check like this,
if (e.Row.Cells[1].Text.Equals("0"))
{
e.Row.Cells[1].Text = "";
}
Hope it helps you.

If I choose Datemodified or Teaser for example, its fine. But I dont seem to have the right syntax for a nested value. Any ideas or am I going about this in the wrong direction?

I am assuming you are loading the xml to a dataset before binding the grid. Since you have nested xml, they will be loaded as different datatables I think. If this is the case, you can use the merge function to marge the datatables in your dataset and get it to display in your grid. This will be my first try.. There are many other way to do this. It all depends on the complixity of your xml structure
|
|
|
|
|
After loading an XML file into DataSet; DataSet creates number of DataTable instances so you have to decide which datatable instance you want to use.
For Example,
DataSet ds=new DataSet();
ds.ReadXml(....);
// List of DataTables
for(int i=0;i<ds.tables.count;i++) {
="" messagebox.show(ds.tables[i].tablename);
}=""

Hi,
I have a GridView which is showing a number of records.
Each record can be grouped by a column called "Status" and there are several possible status values, e.g. New, Open, Closed, Deferred, etc.
I've added a drop-down list and a button which allows me to choose one status value to be displayed in the list. I do this by setting the .FilterExpression property on my GridView and this works great. However, now there are loads of records on the system, I really need to be able to apply one or *more* status values to filter the GridView on. So I'd like to be able to choose, say, "New" and "Deferred".
I started off by adding a number of checkboxes, one for each possible status with the idea that I'd read the values and build a suitable filter expression but it's really clumsy looking.
What I'm looking for is a more elegant way of building up my FilterExpression string using checkboxes. Can anyone suggest an approach?
Thanks - and have a great weekend

Try CheckBoxList
You can iterate through the list and get the text value of each item whose Checked value is True.

how to handle changepassword button click event in changepassword control.
I didn't get its click event plz help...
|
|
|
|
|
The ChangePassword controls changes the password through the MembershipProvider specified in the web.config.
Look into ChangingPassword and ChangedPassword Events. These events will be fired before and after respectively if you click 'Change Password' button.
|
|
|
|
|
why do you need click event of changepassword control. You can use ChangePassword1_ChangingPassword() event instead.
