Cancel closing

I saw the recent post on how to hide the closing button. I need something different. I basically want to do this:

void dockPanel3_Closing(object sender, System.ComponentModel.CancelEventArgs e)

{

dockPanel3.Visible =

false;

e.Cancel =

true;

}

Instead of closing the dockPanel, I just want to hide it so that I can reconstitute it later without losing its contents.

Currently, the "Closing" event is never called, even when I close the whole application.

Thanks.

BindingSource with hierarchic tables

Hello
I am testing the GridView in order to buy it if it answer my needs.
I am lookin for an example of how to bind the gridview to the dataset through a BindingSource.
Something like:

Add relation = "Table1_Table2", "Table1" & "Table2"

masterBindingSource.DataSource = myDataSet;
masterBindingSource.DataMember = "Table1";

detailBindingSource.DataSource = masterBindingSource;
detailBindingSource.DataMember = "Table1_Table2";

gridView1.DataSource = masterBindingSource;
gridView1.DataMember = "Table1_Table2";

In your example i see that i have to create the GridViewTemplate & relation & MasterGridViewTemplate.ChildGridViewTemplate.
But you are not using the BindingSource.

Can you give an example of using a BindingSource for hierarchic of 2 tables?

Thanks Yael

Binding column to checkBox with bindingSource

Hi
I have a Hierarchy GridView.
I bound the dataset to bindingSource, and the Grid to the bindingSource.
The bound works well.
I update the data in the grid through textbox that is bounded to the bindingSource.
I have a column name 'Active' that is 0 or 1. This column is bounded to a checkbox and also works OK.
The problem is when a add new row through the bindingSource:
bindingSource.AddNew();
The new added row is acting strange. A new empty row is added to the grid.
But in the bounded textbox it is showing the former current row with it's values.
When i remove the bind from 'Active' column to the checkbox, the AddNew works fine. The textbox show the new empty row.
When i bind the 'Active' column to a textbox the AddNew works OK.

Can you help me figure out what is wrong?

Adding rows quickly

I want to add 1000 rows to a RadGrid that has 8 columns quickly, and I want the user to see them added real-time.

Currently I'm able to add about 10/second...is that the quickest it can be?

Thanks.

Also, when this is processing (and also later when I update rows) the form itself flickers...suggestions for that as well?

Tool tip Pop up on Mouse over on a Chart

Hi,

I need to show a tool tip pop up on mouse over on a chart.

exact requirement is like:

i have a Line chart with dates on X-axis and double values on Y-axis.

In general on mouse over on any chart we will get tool tip which shows the value at that point.

instead i need to show a pop up kind of thing (like wise context menu/ Data table which has one column and multiple rows) on mouse over.which should have 5 different data items which i need to get from XML/DataBase for that particular date where Mouse was currently placed.

Can any one provide the approach to do this? is this possible with RadControls?
If so please provide some sample application/ Code.

Thanks in advance.

regards,
kiran
