Hi,

When i load an xml file into a datagridview, it loads a few nodes which i rather not load in the datagridview.

This is the content of the xml file:

<root>
<book>
<price>20</price>
<title>whatever</title>
<timeProduced>60958234643051454<timeProduced>
</book>
</root>

And it loads all 3 nodes (price, title and timeProduced);

And i dont want to load the timeProduced node.

This is how i load the xml file into my datagridview:

DataSet xmlDoc = new DataSet();
xmlDoc.ReadXml(path);

this.grdSmsHistory.DataSource = xmlDoc;
this.grdSmsHistory.DataMember = "book";

How can i prevent that?

Thanks in advance!

hi,

i think you can do that by integrating through the DataMember property of the dataGrid ofcourse after assigning the data source for the data grid.

you can do so in the properties panel of the DataGrid.

hope it helps

good luck

Hi,

Thats exactly how i have it although not in the property panel of the datagrid.

I've used DataMember twice, but that caused an error which closed the program.

DataSet xmlDoc = new DataSet();
xmlDoc.ReadXml(path);

<code>xmlDoc.Tables["book"].Columns.Remove("timeProduced");</code>

this.grdSmsHistory.DataSource = xmlDoc;
this.grdSmsHistory.DataMember = "book";

Deleting item from listview error...

Hi all,

If i have selected the last item in the listview... example the index is 3 that means it is the fourth item, right... if i delete this item... and refresh the listview, i get an error that says: "InvalidArgument=Value of '3' is not valid for index. Parameter name: index". I think this is because it tries to select the deleted item again as this was the last item selected before the delete and refresh. How do i clear the index as so that there is no selected item?

Thank you in advance...

After deleting the item from the listview, are you using the index property somewhere?

Because when you delete the item from the listview, its value from the selectedindices collection is also deleted.

Check once?

System.Windows.Forms.ItemCheckEventArgs e
to delete the item from the arry we have:

//remove the item from the arraylist<br />
_myArrayList.RemoveAt(e.Index);

After we removed the item from the arraylist... we clear the items from the listview and for each entry in the arraylist we add into the listview...

export OLAP in SSAS 2005 to excel pivot table

Hi genius,

Nice to meet you here!

When developing BI programs with SQL Server 2005, I got this problem:
Users want the report should be exported in office excel 2003 format, and stored in PIVOT TABLE.
We have decided to use OLAP tech in SSAS(SQL Server2005 Analysis Services) to generate cubes.
If we just use excel as a client tool, and create a pivot table which connects to the cube database, it's ok.
But, the users want to download the excel file from a web page, further more , they want to filter the data through the web page.

How can I do?

Help inline.

Thank you!

CurrencyManager and threading

Hi everyone,

I'm sure i've read everything i can find on the web about CurrencyManager and Databinding and I still can't find a (good) answer to a really annoying problem.

I've solved the problem enough to get development moving again but the hack breaks every law of OO programming known to man and i'm sure will cause other problems for me down the line.

I'm trying to raise an event from a collection class that has its data updated by a class that sits monitoring some web services on a background thread. This collection is bound to a DataGridView. When data arrive in the collection class it raises a ListChanged Event. I then get the delightful cross-threading... error. I've tried inspecting the ListChanged.Target and it's a CurrencyManager Object. I've looked at the CurrencyManager object on MSDN and it has no Invoke method. I thought cool it's got a bindings collection, one of those will be a control and i'll invoke against that, this seemed to make sense until i realised that there were 0 items in the bindings collection.

My truly filthy hack is to pass a control from the UI into the monitoring class. This is obviously very wrong as this class should know nothing about the objects connected to it.

Does anyone know how to find a control given a CurrencyManager, why i don't appear to have any items in the bindings collection or how i can get my event to fire on the UI thread by any other means.

Thanks in advance,

Russell

How to handle "New string added" event in ListBox?

Hi Everybody,

I have a multi-column listbox.
I need to change the width of the listbox,
based on the string length. I've written
the code in a function 'ResetLBWidth'.

This function should get called whenever I add a
string to the list box. How can I handle this?
I don't find any event like "NewItemAdded"..

Suggest me a path to achieve this.

Thanks in advance,
Sarvan AL

There is no any event like "NewItemAdded" for listbox.

If you are mannually filling the listbox then the whole control is in your hand. You can call the method ResetLBWidth where you are adding the data to listbox.

If you have assigned some data source to the list box and your data source is changing then you have DataSourceChanged event to map.
