Programmatically adding TabPage Contents into DataGrid from XML File 1

[annethorne]

Hi,

We are creating a C# Windows application using VS 2005.

It reads in an xml file and creates tab pages that each
have a datagrid that holds the specific information
for that tab's node.

We have been able to programmatically give the tab.text
(the label on the tabs), but when we try to add the
specific data for each tab into a datagrid on the
tab's page, all of the data gets added instead of the
data for just that node.

Perhaps we need to clear the grid first???

Any help would be appreciated.

Thank you in advance,
Anne




Here is a portion of the xml file we are using.

Hi Anne,

I've had a quick look at your code, I can see that you are creating the tabpage and then creating the abcPage for the tab page. However within the InitializeComponent of abcPage, there is use of pannel.

this.panel1 = new System.Windows.Forms.Panel();

I would have thought that you would be connecting the datagrid to the tabpage not the pannel of the form. This may mean that instead of getting a data grid for each tab page, You get a single datagrid for your form.

I haven't tried this myself, but if it was my program this is what I would be having a look at.

I hope this helps

Good Luck
MJ
