How to reset a gridcontrol ?

[Puthirak OM]

Hi,

How can i reset a GridControl object ?
i.e. i want to reset a GridControl object to it's initial state
(the state when it was first allocated).

I'm using SyncFusion Essential Studio WPF 7.3.0.20

Thanks.

Hi Puthirak,

Thanks for using Syncfusion products. The GridControl works totally on how you define the styles, either through QueryCellInfo or manually setting those styles.

(1) Through QueryCellInfo, then you would have an underlying store, which you could simply set it to NULL and reset the Model.RowCount and Model.ColumnCount.

(2) Manually applying styles, then you simply clear the internal lists maintained in the Model as,

this.grid.Model..VolatileCellStyles.Clear();
this.grid.Model.Data.Clear();

Finally, you would have to force the grid to refresh,

this.grid.InvalidateCells();

Hi,

Thank you for your quick answer.
But unfortunately, it didn't help me solve my problem.

My problem concern the interaction between the selection
and the covered cell.

After several "reset" of the grid, the selection of the covered cell doesn't work properly, i.e. the selection doesn't cover all the covered cell.

I've join a code snippet where you can reproduce the problem.
You need to switch mode several time and play with the selection
between each switch.

Hi Puthirak,

Thanks for the sample. The CoveredCells.Ranges had to be refreshed internally to make the selection work, We added a new method called InvalidateRanges(), that would clear out the CoveredCells.Ranges. For now, I added a workaround in your sample to make it work. If you need this fix, you can download the next week's development build that would be published in our website.

Hi,

Again thank you for your quick answer.
The file that you'd attached seems to be missing.
I'm looking forward to the next week build.

Any equivalence of InvalidateCells(); in a GridDataControl?
By the way, I found amazing that the grid's display is stil working even if we destroy the ItemsSource.
Where can I find a real explanation of the GridDataControl behaviour?

Actually, I don't want to reset the grid, I just want to change its ItemsSource.
The amazing thing is that if change the ItemsSource, the grid is still linked to the old ItemsSource.

Hi Puthirak,

Thanks for your interest.

We have added the new property named “ClearAllOnItemSourceChange” in our latest RC build published in the below forum :

http://www.syncfusion.com/support/forums/general/91019/essential-studio-2009-vol4-rc-v74015-available-for-download.

You can clear all the link related to the Old ItemsSource by using this property. Use the below code for enable this property.

[Xaml]

x:Name="grid"
AutoPopulateColumns="True"
AutoPopulateRelations="False"
ClearAllOnItemSourceChange="True">


Please let us know if you need any more details.

Thanks
Ganesan.

In 8.2 how do I reset the filter on a GridDataControl? I'm reusing the same GridDataControl object bound to a given class object (collection) which I then clear and repopulate as needed but the filktering stays intact.
