Getting xml from GridView datasource

Hi there,

I'm trying to generate xml from the datasource of rad gridview. Following is how I'm binding data to the grid:

radgvParticulars.MasterGridViewTemplate.DataSource = dsTODetails.Tables[1];

I'm wrote the following code to extract the xml from the datasource:

DataSet ds = (DataSet)radgvParticulars.DataSource;
string strXml = ds.GetXml();

This throws an InvalidCastException - "Unable to cast DataTable object to DataSet object". Then I tried the same by writing the below code:

DataTable dt = new DataTable();
dt = (DataTable)radgvParticulars.DataSource;
DataSet dsnew = new DataSet();
dsnew.Tables.Add(dt);
string strXml = dsnew.GetXml();

But this throws another exception: "DataTable already belongs to another DataSet".

I'm unable to proceed further. Pls help.

Regards,
Pramod Goutham.

RadChildFrom Minimum Size

Hello i am using several RadForms as child forms for an mdi. Part of this is letting the user decide the size of each RadForm by entering values in textboxes(height and width textboxes). I have tried to put the resizing of forms in the text changed events, but that does not seem to be working, as the radform seems to default to a different size before the user has a chance to enter the full value. Why is this? I have tried setting the minimum size of these radforms to be really small as well, but it still seems to default to some other values. On a seperate note, i had this functionality with the resizing in the Leave event of the textbox. However the problem with that is if the user has entered values for a child form, and clicks on a different child form, it resizes the new child form instead. All these child forms are being created at run time and i am using Winforms Q2 SP1 2008. A work around for either one of those cases would be good. Thanks in advance.

Alt. Rad Control question

I am using the carousel control in my app because of the gradient background and itemreflection properties.

Do you have any other controls, such as a panel control, that will allow me to add labels and have it reflect on the parent control? I also need to be able to add a gradient as well.

Bug in RadTrackbar?

When using a RadTrackbar with a minimum value below 0 and maximum above 0, setting the value 0 zero sets the handle to the wrong position.

So let's say the minimum is -50 and the maximum +50 setting the value to 0 should position the tracker in the middle. But it sets it to the farmost left.

Is this a bug?

Thanks,
Gerard van Eldik.

GridViewCheckBoxColumn has strange border in filter row

Hi,

I'm using a GridViewCheckBoxColumn in a filter grid, that I'm adding at run time. If there are no rows in the table whe the column is added, the checkbox in the filter row has a strange half square at the bottom and the gradient background of the checkbox is gone. This is also the case if I add the checkbox column before I add the row. All the other checkboxes (in the data rows) look normal. On the other hand, if I add the rows first, then the checkbox column, the checkbox in the filter row looks just like all the others.

Any ideas on how to fix this would be appreciated.

Thanks,
Kevin
