Hello Markus,

You can set the Edit property for each of the items from the detail table to true and invoke the Rebind() method for the corresponding child table to switch it in edit mode (the same approach presented for the master table from the help article linked in one of my previous replies).

To familiarize with the client/server API of RadGrid review the help articles linked below:

Hello Stephen,

thx for your help, I really appreciate your patience.

I already know the links your provided, but still I think that these helppages should go into more detail. A page that explains every single method and every single property would be great.

Anyway, back to my problem :-) :
I have a button on the page that switches to edit mode:

protected void btnEdit_Click(object sender, EventArgs e)
        {
            PutGridInEditMode();
            rgActionItems.Rebind(); //RadGrid
        }

        private void PutGridInEditMode()
        {
            int maxIndex = rgActionItems.Items.Count;
            for (int i = 0; i < maxIndex; i++)
            {
                rgActionItems.EditIndexes.Add(i);
            }
        }

Now, as the page is in editmode, I want to open every detailtable in editmode as well:

protected void rgActionItems_DetailTableDatabind(object sender, GridDetailTableDataBindEventArgs e)
        {
            ICollection<IKindActivity> coll = (ICollection<IKindActivity>)rgActionItems.DataSource;
            GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
            string mnId = dataItem.GetDataKeyValue("Id").ToString();

            foreach (IParent parent in coll)
            {
                if (parent.Id.Equals(mnId))
                {
                    e.DetailTableView.DataSource = parent.childElements;
                }
            }
        }

        protected void rgActionItems_TablePreRender(object sender, EventArgs e)
        {
            foreach(GridDataItem gdi in rgActionItems.MasterTableView.Items)
            {
                if(gdi.ChildItem.NestedTableViews.Length > 0)
                {
                    foreach (GridTableView view in gdi.ChildItem.NestedTableViews)
                    {
                        if (rgActionItems.EditIndexes.Count > 0)
                        {
                            foreach (GridDataItem gdi2 in view.Items)
                            {
                                gdi2.Edit = true;
                            }
                            //view.Rebind() throws NullPointerException
                        }
                    }
                }
            }

        }

The Items appear yellow, which should indicate that they are in editmode, but I can't edit the detailtables, only the parents.
If I remove gdi2.Edit = true, the detailtables are white, so gdi2.Edit does at least something, but not what it should do.
Please also see that xxx.Rebind() always throws a nullpointer exception, allthough the invoked methods (NeedDataSource etc.) don't throw any exception.
I also tried adding an EditButtonColumn, this approach puts the cells in editmode as expected - but this approach isn't appreciated by our customer.

Thx in advance for your help and kind regards

Alright, finally I "solved" this issue:

I set up a sample project that should demonstrate the problem, but everything worked out well there. I realized another bug (setting EditMode to InPlace in the codebehind class which avoids further detailtable loading) but the main thing worked well.
I then added the property "EditMode="InPlace"" in my project and suddenly everything worked in my solution too.
If I remove the "EditMode" property in the sampleproject, the project is still working. I hope I can reproduce the error somehow, b/c I really think this behaviour is kind of weird.

Should I open a support ticket that demonstrates this EditMode thing? I actually didn't investigate this behaviour any further b/c I don't need it in my project. Perhaps these problems are connected somehow.
Kind regards
