Hey Andi,

Just wondering if this issue has been resolved yet as it is a bit of pain having to a Response.Redirect after every batch update.

Regards,

Adrian.

Handy,

Been having problems posting to this site, some internal issues, so please disregard this post as it is a test for me.

Glen,

I figured out what the issue was.  My original version had the markup defining the layout of the gird which never quite worked so I configured my grid in the Code-Behind in the PrepareDataBinding method.

However, I never actually removed the markup which was somehow interfering with the layout generated by the code-behind, so I removed the markup and this has resolved my issue.

Regards,

Adrian.

Glen,

I have already been using the settings that you provided and it still doesn't work. There is some slighly strange behaviour, let me explain some more.

I configure my hierarchical grid in the PrepareDataBinding method in the code behind:

WebGridColumnCollection rootColumns = grdEDMPortfolios.RootTable.Columns;
rootColumns.Insert(0, new WebGridColumn("chkEDM", AWBConstants.COL_REGISTRATION_ID, " ", new Unit("23px"), ColumnType.CheckBox, EditType.Checkbox, ""));
rootColumns.GetNamedItem("chkEDM").IsRowChecker = true;

WebGridTable childTable = grdEDMPortfolios.RootTable.ChildTables[0];
WebGridColumnCollection childColumns = grdEDMPortfolios.RootTable.ChildTables[0].Columns;
childColumns.Insert(0, new WebGridColumn("chkPortfolio", AWBConstants.COL_PORTFOLIO_ID, " ", new Unit("23px"), ColumnType.CheckBox, EditType.Checkbox, ""));
childColumns.GetNamedItem("chkPortfolio").IsRowChecker = true;

Here I hide various columns I don't need as well as added my parent row checker column "chkEDM" and my child row checker column "chkPortfolio". The grid layout settings you stated above are set in the markup.

I have also added a client side OnCheckBoxClick function to trigger a parent checkbox to check all children and vice versa. Here is is the code:

    function grdEDMPortfolios_CheckBoxClick(gridId, tblName, colName, checkboxValue)
    {
        var grid = ISGetObject(gridId);
        var selectedRow = grid.GetSelectedObject().GetRowObject();

        if (colName == "chkEDM")
        {

            if (selectedRow.Table.ChildTables.length > 0)
            {

                var childRows = selectedRow.GetChildRows("PortfolioCollection");
                for (var i = 0; i < childRows.length; i++)
                {
                    if(!childRows[i].GetCells().GetNamedItem("chkPortfolio").ForceNoEdit)
                    {
                        if (checkboxValue)
                        {
                            childRows[i].Check();
                        }
                        else
                        {
                            childRows[i].Uncheck();
                        }
                    }
                }
            }
        }
        EnableCopyToShell();
        return true;
    }

The behaviour I witness is as follows:

1. Click on one of the child check boxes.
2. Click the grid's refresh icon
3. The child checkbox is persisted after the grid refreshes.
4. Click on the child checkbox again then click refresh.
5. After refresh all child checkboxes are selected even though only one was selected.

Glen,

Is it not possible at all to:

• Define the hierarchical grid structure client side
• use the concrete collection classes e.g. CustomerCollection, OrderCollection - which impletement IHierarchicalList and IObjectRelates
• Populate Parent collection class and all of its children
• Then bind the grid in the IntializeDataSource method like I did earlier and have the grid display correctly.
