Issue deleting last row from Grouping DataGrid

[Gopinath Jayamuni]

Hi,

I am facing issue when i delete last row from the grid and try to select any of the other row from the grid. Datagrid datasource is custom collection. Please find attached a sample application using which you would be able to replicate the issue.

Steps to replicate the issue
1. Check the checkbox of last row and click on "Delete" button.
2. Again check the checkbox of the last row and click on "Delete" button"
3. Now try selecting or DoubleClick any of the row,
following error message is displayed
"Specified argument was out of the range of valid values.Parameter name: Index was out of range. Must be non-negative and less than the size of the collection."

Even though my actual application is more complex (event based & database driven) than the attached sample application the issue that i am facing is the same.

Environment :
Visual Studion 2003
Sysncfusion version 4.101.0.50

Thanks,
Gopi

Hi Gopi,

You need to change the position of the CurrencyManager before the delete the record from the GridTable. Below is a code snippet

this._gridNoteSearch.Table.GetCurrencyManager().Position -= 1;

Hi Haneef,

Thanks for your reply. Your sample code solves
the issue that i was facing but i have one more issue that stills persists even with your fix. I have modified your sample code inorder to replicate it in the application.

Please follow the below steps inorder to replicate the issue.
Step 1 : Double click on the last row of the grid. This will pop up a window.
Step 2. Click on the "Delete" button in the popup window.
Step 3. Once i delete the record from the custom collection system throws exception "Specified argument was out of the range of valid values"

I am unable to trap/avoid this error. It will be of great help if u can give fix this issue.

Hi Gopi,

You can change the position of the CurrencyManager before the delete the record from the grid. Here is a code snippet

if( this.manager != null )
this.manager.Position -= 1;
int index = _criterias.CriteriaList.IndexOfCriteriaId(_criteria.Id);
_criterias.CriteriaList.RemoveAt(index);
this.Close();
