Change child row in datasource doesn''t affect the expanded grid

[Evgeny Tishkin]

I've created hierarchical grid using Customers sample and tried to change Child customer in datasource having all the grid expanded. But this datasource change didn't update the corresponding child row in the grid. I had to reexpand parent row to see the changes.

What is the best work around for this problem?

Thanks,
Evgeny

Hi Evgeny,

You can call the Table.EndEdit method to commit the changes in a grid. Here is a code snippet.

this.grid.GetTable("TableName").TableDirty = true;
this.grid.GetTable("TableName").EndEdit(); // commit the changes in a grid.
this.grid.GetTableControl("TableName").Refresh();

Best regards,
Haneef

Haneef,

Is refreshing the whole grid the best workaround for updating one child row in grid?

Isn't it the grid bug? We came accross it even in Syncfusion 2.x.

Thanks,

No, you can refresh the particular row by using the RefreshRange method. Below is a code snippet.

this.grid.GetTableControl("TableName").RefreshRange(GridRangeInfo.Row(updateRowIndex));

It won't help in case we need to add or remove child rows. Only collapse->expand parent row can help. That is rather clunky and slow.
