FIX. RadGridView - having groups, filters, sort descriptors and search query in the GridViewSearchRowInfo may leave the grid in an invalid state
Workaround: handle the SortChanging and FilterChanging events and clear the search criteria from the search row. The stored search string can later be restored in the SortChanged and FilterChanged events

string filter = string.Empty;
private void RadGrid_FilterChanged(object sender, GridViewCollectionChangedEventArgs e)
{
    this.radGrid.MasterView.TableSearchRow.Search(filter);
}

private void RadGrid_SortChanged(object sender, GridViewCollectionChangedEventArgs e)
{
    this.radGrid.MasterView.TableSearchRow.Search(filter);
}

private void RadGrid_SortChanging(object sender, GridViewCollectionChangingEventArgs e)
{
    this.filter = this.radGrid.MasterView.TableSearchRow.SearchCriteria;
    this.radGrid.MasterView.TableSearchRow.Search(null);
}

private void RadGrid_FilterChanging(object sender, GridViewCollectionChangingEventArgs e)
{
    this.filter = this.radGrid.MasterView.TableSearchRow.SearchCriteria;
    this.radGrid.MasterView.TableSearchRow.Search(null);
}

Hi Kamel,

The search feature in RadGridView is working asynchronously. At the moment two independent async operations are happening at the same time, the first one is the default async implementation of the search and the other one is the async update in the project. At some point this results in an invalid state of the grid causing the error. We have investigated the discussed scenario in details and we have decided to introduce a new property IsSearchAsync. The default value of the property will be set to true. Setting the property to false would perform the search synchronously and with this setting the discussed in the issue exception should not be thrown. 

The R2 2018 SP1 release is scheduled for later this month, approximately around 20.06.2018.

Regards,
Hristo

Hello,

The issue is being investigated at the moment and likely it will be resolved for the R2 2018 release. At the moment, however, I cannot confirm an estimated date for the fix. You can subscribe to the item and be updated when its status changes.

Dear CustomerService,

We have the same issue on one of our Solution which is impacting several hundreds users with a around (1 crash / user / day). The provided workaround suggesting to empty the Searchbox is not satisfactory.

When could you provide a new version with this important fix?

Thank you and best regards,

Kamel
