In Datagrid the Error tooltip does not pop up even though ErrorIcon is displayed
-
Hi, i have made a form which follows the following logic :- The form displays various panels which are used to get criterias from the user. then form.layout is suspended and the following algorithm executes : 1. Based on these criterias i add various column to a datatable say dtRecordsReturned. 2. Then datagridcolumnstyles [some of them are instances of classes i inherited from datagridcolumnstyle] are made and added to a datagridtablestyle , which is then added to the TableStyle property of a datagrid say dgRecordsReturned. 3. the dtRecordsReturned is then bound to a dataview dvRecordsReturned. 4. dvRecordsReturned is bound to the dgRecordsReturned. 5. then records(rows) are added to dtRecordsReturned by executing a sqlQuery. 6. Then Values of some of the columns of each row are set according to the criterias got from the user. While doing this some special conditions may arise, which i am displaying to the user by setting an errormessage on that particulare column by calling .SetColumnError(columnname,strSpecialContidionDescription). 7. then the panel [pnlRecordsReturned] which contains dgRecordsReturned is brought to the front by calling pnlRecordsReturned.BringToFront(). 8.Finally the form.Resumelayout() is called. Now the Problem i am facing is that though the ColumnErrorIcon is displayed in the columns, no tooltip message pops up when the cursor is hovered over the icon. I tried using .RowError instead of .SetColumnError still the result is similar. ErrorIcon appears in the rowheader but no tooltip message pops up. Any Suggestions? Thanks
