GridDataItem - Text is Empty when Visible = false

[Lars]

Hi Telerik,

since the Version 2013.1.220.35 we have a problem accessing data on the "old" way.

If you have a GridBoundColumn, which is set to Visible=false, the Text Field is not rendered anymore.

So an access like

GridDataItem item = e.Item as GridDataItem;

string Value = item["columnID"].Text;

does not work anymore. I get a "  " as result.

I know, that this is not the correct way, to access data. We do it like

string Value = item.GetDataKeyValue("ID")

in most scenarios. (<MasterTableView DataKeyNames="ID">) needed of course.


But is this a feature in the new Version, or is it a bug.
We have to clear this, because we will have many adaptions in the application, if this is not supported anymore!

Thanks for your help.

Hi,

This is reported as a bug with the latest version of controls. Try setting Display property as false instead and access the column value.

Thanks,

Hi,

There is a difference between "Breaking Change" and a "Bug". The difference is that the "Breaking Change" is done intentionally to provide better functionality, but since it is braking the previous functionality we are informing everyone that they may observe such a change and what are the possible ways for the moment.

On the other hand a bug is unexpected behavior that was not intentionally introduced and that is causing the control to behave abnormally.

With all this said, the accessing of columns marked as Visible=False won't be possible for future versions as it was done intentionally to increase the performance of the control. More information on what approaches are supported could be found in this sticky thread.

I hope this information helps to distinguish both terms.

All the best,
Andrey

Hi

don't use Visible="false" on your GridBoundColumn/GridNumericColumn.

try this to hidden your collumn and still get the value :

RadGrid1.MasterTableView.GetColumn("UniqueName").Display = False
