ExtractValues & hotfix 1425

[Piyush Bhatt]

After applying hotfix 1425 - my code to extract values is failing. This is what I have:

- A grid with few columns and a selection checkbox.
- A button outside of grid.
- I select the checkbox
- click the button and on server side I do following in OnClick of button:

GridEditableItem selRow = grid1.SelectedItems[0] as GridEditableItem;
        Hashtable rowValues = new Hashtable();
        //get row values
        selRow.ExtractValues(rowValues);

        //set values from the selected row
        DateTime date = MyConverter.ToDateTime(rowValues["Date"], DateTime.MinValue);

----
the ExtractValues() function does not give error but all values inside the hashtable are null. The keys are correct, but no values!

Why? This was working find in earlier version of release but started breaking after 1425. Please help us soon.

Thanks,
Piyush

Hello Piyush,

Do you use InPlace editing for your grid? In case you use EditForms edit mode, note that you will need to invoke ExtractValues() method for the respective GridEditFormItem instead, namely:

GridEditFormItem selRow = (grid1.SelectedItems[0] as GridDataItem).EditFormItem as GridEditFormItem;
Hashtable rowValues = new Hashtable();
//get row values
selRow.ExtractValues(rowValues);

Detailed explanation about the inplace and edit forms edit mode specifics can be found in the online help.

No I don't have Inplace editing in my grid. The grid is for readonly purpose and used only to select a row. What should I do in this case?

Hello Piyush,

Review the explanation/linked article from my previous reply and let me know whether this helps. The ExtractValues method is used to extract the data from the editable fields in the grid.

As I explained in the earlier mails, I am not doing this in any grid events. I am doing it outside of a grid events. So, none of the extractValues helped in that case.

Finally I used
DataItem selRow = RadGrid1.selectedItems[0] as GridDataItem;
selRow["WhateverUniqueColumnName"].Text  - to get the value.

Its working in 1425 - I hope you are not planning to stop this.

Thanks,
Piyush

Hi Piyush,

The ExtractValues(dictionaryObj) method fetches the data from editable grid rows only. If you want to get the values from the selected grid item, this can be done through the Text property of the corresponding cell.
