It appears there is some kind of issue with calling ClearDataSource on a postback and the presence of the "Multiple controls with the same ID error" being thrown when a Template control exists in the WebDataGrid.
I have a template column with a checkbox and if I use the ClearDataSource call before rebinding the WebDataGrid on a postback I get the "Multiple controls..." error presumably related to the checkbox. If I comment out the ClearDataSource my postback works just fine and I don't get the fatal error but then, even though I'm rebinding the WebDataGrid (with a refreshed object List<T> collection pulled from the db) on the postback, the OnInitializeRow event handler does not fire again - it will fire on the intiial page load and that's it - which also is a problem as I set some custom cell tooltips when the InitializeRow event is fired - seem's I'm darned if I do, and darned if I don't. Anyone have any thoughts.
Hello majensen,
There was a very similar development issue. Would you test your project with the latest service release for your version, and check whether this error still happens.

I am facing the same issue. has this been fixed in a later release?
It is not fixed as of 2010.3 SR 2056 - I am trying to work with Infragistics to get it resolved - I provided an example solution to them.
I've got this same error as well. This has been fixed in the past for us back in 2009.2 I think.
Managed to find a workaround. Add
"grid.Rows.Clear();"
Before calling ClearDataSource.
Hi,
It is strange in my case.
When on local development machine, I try to open the page it gives me same id error.
Then I access the development server from a remote machine, the page opens with no problem.
Then I open locally and now it opens...
I tried grid.rows.clear() it worked now, but I do not know it is beacuse I first logged from a remote
machine or not... (my version is 10.V3.2120)
Cheers
I have the same problem with WebDataGrid Version=10.3.20103.2073, and the DataBind code below
private void BindData()
{ this.WebDataGrid1.Rows.Clear(); this.WebDataGrid1.ClearDataSource(); this.WebDataGrid1.DataSource = this.ods_DataPointValueSet.Select(); this.WebDataGrid1.DataBind(); //this.WebDataGrid1.DataSourceID = "ods_DataPointValueSet"; //.DataSource = this.ods_DataPointValueSet.Select(); }
The workaround is also not working for me. Getting the same error with 10.3.20103.2073
Tried the workaround - regretfully it does not work for me - get the same error regarding duplicate control id's - this is in 10.3.20103.2056.
