Problem with Rebind() in DataGrid

[Sathya]

void rdItemsGrid_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "UpdateAll")

{

foreach (GridDataItem editedItem in rdItemsGrid.EditItems)

{

if (editedItem.EditFormItem.IsInEditMode)

UpdateItemPermission(editedItem.EditFormItem);

}

rdItemsGrid.Rebind();

}

else if (e.CommandName == "Update")
{
if (e.Item.IsInEditMode)
UpdateItemPermission(e.Item as GridEditableItem);
rdItemsGrid.Rebind();
}
}

The Rebind() method which is used in Update All block works fine. But when i call the Rebind method in the Update block, which is highlighted in red, I get the following Error.

DataBinding: ' System.Data.DataRowView' does not contain a property with the name '....'

Description: An unhandled exception occured during the execution of the current web reequest.Please review the stack trace for more information about the error and from where it originated in the code.

Exception details: System.Web.HttpException :DataBinding: ' System.Data.DataRowView' does not contain a property with the name '....

Can you kindly help me in solving this issue.

Hi Sathya,

Commands like Edit, Update, Delete etc will call Rebind() implicitly, you don't have to call Rebind() explicitly. You can also refer the following help article which explains the Grid commands that call the Rebind implicitly.

Thanks

Actually the problem is, i have a master table and  detail table. When i update the value in the detail table, the detail table values are pefectly updated. But at the same time i want the updated values to be reflected in the master table.So i tried to used this Rebind() method.

What should i do to reflect the detail table values both in the master table as well as the detail table?

Hi Jana!

I'm having exactly the sam problem.
When I update a record in the detailtable (with an usercontrol edit form), I can update the detailtable with the following code:

 

 

If

 

(e.CommandName = RadGrid.PerformInsertCommandName) Then

 

 

 

e.Item.OwnerTableView.Rebind()

 

End

 

If

 

However if I try something similar to refresh the mastertable:

 

e.Item.OwnerTableView.ParentItem.OwnerTableView.Rebind()
or
radgrid1.MasterTableView.Rebind()

I get the following error:

Cannot unregister UpdatePanel with ID "..." since it was
not registered with the ScriptManager. This might occur if the
UpdatePanel was removed from the control tree and later added again,
which is not supported.

Did you manage to solve this issue?
Thanks in advance,

Ricardo.

Hi Ricardo,

This seems like a problem with the ajax settings, for example when using an AjaxManager.
If the issue persists, you can open a formal support ticket, and send us a small project, demonstrating your setup, for additional review.

I had this same issue.  I have discovered a workaround, although if there's a better solution I'd love to see it.

But to fix the issue, I just had a flag in the code behind of the page, called "RebindGrid" that i declared and initialize to false, then in the itemCommand handler I set it to true, then in the Page_PreRender event, i check it, and if true, I call RadGrid.Rebind().  that seems to do the trick.  for some reason, you just can't call it from within the ItemCommand handler, but you can call it on any other event handler in the page.
