Repopulating and Reselecting same Row in DevExpress Grid
Repopulating and Reselecting Rows in DevExpress Grid
In a DevExpress Grid control, reselecting a row after repopulating the grid involves preserving the key value of the selected row and then reselecting it using the updated data. Below is a step-by-step guide to achieve this:
1. Save the Key Value of the Selected Row
When a user selects a row, save the key value of that row. The key value is usually obtained from the underlying data source. Replace "YourKeyFieldName"
with the actual field name that represents the unique key for each row.
2. Repopulate the Grid
After repopulating the grid with updated data, update the grid's data source and refresh the view.
// Repopulate your grid here (e.g., fetching updated data from the database) yourGridControl.DataSource = GetUpdatedData(); yourGridControl.RefreshDataSource();
3. Re-select the Row Using the Key Value
Find the new index of the row with the saved key value and select it.
int newIndex = gridView.LocateByValue("YourKeyFieldName", selectedRowKey); gridView.FocusedRowHandle = newIndex; gridView.SelectRow(newIndex);
Replace "YourKeyFieldName"
with the actual field name used as the key.
Make sure to handle cases where the key value might not exist in the updated data (i.e., the row was deleted or the key value changed).
This approach assumes that your grid is bound to a data source where each row has a unique key. Adjust the field names and types according to your specific implementation.
So now you can select any row in devexpress gridview and after rebinding the grid the same row will be selected.
