Hi Melba,
I'm attaching the example again. Please let me know if you still have trouble retieving this. I'm using version 5.102.0.37
The steps you listed are not what I'm doing. The second dropdown gets populated by selecting a different option from the first drop down, not by clicking the button.
1. Create sample with 2 dropdowns and 1 button.
2. Both dropdowns are populated with data on initial entry.
3. Select a different option in first dropdown. The second dropdown gets repopulated with data based on first dropdown selection.
4. Select an option in dropdown 2. Click the button. You'll see that the selected value from dropdown 2 does not reflect what was just populated using the callback from changing value in dropdown 1. The selected value from dropdown 1 is correct.
The scenario that I'm working with is that the user changes dropdown1 which causes data in dropdown2 to change - I'm using the syncfusion callback to accomplish this. Then they click a button to run an excel report but the value in dropdown2 is not getting saved so when I run the report using the selected value from dropdown2, I'm always getting the initial value, not the value that was just repopulated by the callback.
Hope I'm explaining this. If you can't open my example, I can try to copy and paste here.
Thanks
