DataGrid - Sorting Problem

[Mubashar Ahmad]

Dear Frnds

I m using DataGrid Control in my project.

On the mouse Up event i get the information from DataGrid row using Currencty Manager. code is below

private void dgPassengers_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)

{

string tHistoryId;

if (dsInquiry.Tables["QueryHistory"].DefaultView.Count > 0)

{

HistoryId = ((DataRowView)cmQuery.Current).Row["HistoryID"].ToString();

this.HistoryId = tHistoryId;

this.DoAction(InquiryActions.EditQuery);

}

}

it is working fine. but when i click on the Column header it sorts the Grid and it should also give the information of the row where the Record pointer is located. but it gives wrong information.

or we can say it doesn't move the record pointer to the row it was pointing before sorting.

please give suggestion

thanks and regards

Hello,

The data grid won't retain its current position after being re-sorted. You
should restore the position manually, possibly by remembering a unique row
primary key and searching the row's position in the updated data view
accessible through the CurrencyManager's List property by the stored primary
key.

Thanks Dmitriy Lapshin

your suggestion is quit reasonable now please let me know how can i capture
sort event. i dont think that datagrid provides such event. and tell me also
is it a event of dataGrid or
DataGridColumn.

thanks once again and Regards

There's no dedicated event. You can capture the grid's MouseDown event and
determine whether the user has clicked on a column header by using the
grid's HitTest method.
