My hunch is that it is not a MinWidth issue, as I have experienced these in the past - though I'm not 100% certain.

The version of the control I am using is 8.3

It would be great if you could post a small sample project that we could run to demonstrate the error. With a code snippet, there are just too many unknowns.

Yes the RowLayouts are very complex.  Icreate a hierarchical view of the datasets.  My hunch is that it IS a bug.  The code is pretty complex I'm not sure if you can reproduce because it may be hard to figure out, but I'll post it anyways:

First I have to create a hierarchical data set:

private DataSet CreateHierarchicalDataSet(DataTable v_DataTable, Int32 v_highestLevel)

        {

            // declare a new DataSet

            DataSet hierarchicalDataSet = new DataSet("HierarchicalDataSet");

            // pass DataTable for each hierarchical level

            Int32 intLevel = default(Int32);

            for (intLevel = 0; intLevel <= v_highestLevel; intLevel++)

            {

                // pass DataTable and extract rows for this level

                DataRow[] levelDataRows = null;

                levelDataRows = v_DataTable.Select("SortLevel=" + intLevel.ToString());

                // test to see if any rows were selected

                if ((levelDataRows != null))

                {

                    // create a new data table and add the rows and columns

                    DataTable levelDataTable = new DataTable();

                    levelDataTable = v_DataTable.Clone();

                    levelDataTable.TableName = "SortLevel" + intLevel.ToString();

                    DataRow dataRow = null;

                    foreach (DataRow dataRow_loopVariable in levelDataRows)

                    {

                        dataRow = dataRow_loopVariable;

                        DataColumn dataColumn = null;

                        DataRow newDataRow = levelDataTable.NewRow();

                        foreach (DataColumn dataColumn_loopVariable in v_DataTable.Columns)

                        {

                            dataColumn = dataColumn_loopVariable;

                            newDataRow[dataColumn.ColumnName] = dataRow[dataColumn.ColumnName];

                        }

                        levelDataTable.Rows.Add(newDataRow);

                    }

                    // create a primary key and add to the data table

                    DataColumn[] Keys = new DataColumn[1];

                    Keys[0] = levelDataTable.Columns["SortID"];

                    levelDataTable.PrimaryKey = Keys;

                    // add table to DataSet

                    hierarchicalDataSet.Tables.Add(levelDataTable);

                    // if this is >= level 1 then create and add relationship

                    if (intLevel >= 1)

                    {

                        Int32 intParentLevel = intLevel - 1;

                        string strThisLevel = "SortLevel" + intLevel.ToString();

                        string strParentLevel = "SortLevel" + intParentLevel.ToString();

                        DataRelation relLevel = new DataRelation(strThisLevel, hierarchicalDataSet.Tables[strParentLevel].Columns["SortID"], hierarchicalDataSet.Tables[strThisLevel].Columns["SortIDLink"]);

                        hierarchicalDataSet.Relations.Add(relLevel);

                    }

                }

            }

            return hierarchicalDataSet;

        }

Sort level = depth of the tree.

SortID is the primary key

SortIDLink is  the row's link to a parent node (if not the top most row [SortLevel = 0]).

In the InitializeRow Event:

void TransactionGrid_InitializeRow(object sender, InitializeRowEventArgs e)

        {

            // attempt to turn off expansion indicator

            if (e.Row.HasChild())

            {

                e.Row.ExpansionIndicator = ShowExpansionIndicator.Always;

            }

            else

            {

                e.Row.ExpandAll();

            }

            //Comment Column

        }

Once the dataTable is populated I will construct a demo  table:

public DataSet MakeTable(DataSet dtsTemp)

       {

           DataTable dt = new DataTable();

           dt.TableName = "Clients";

           dtsTemp.Tables.Add(dt);

           dt.Columns.Add("Amount", typeof(System.Int32));

           dt.Columns.Add("Name", typeof(System.String));

           dt.Columns.Add("SortID", typeof(System.Int32));

           dt.Columns.Add("SortIDLink", typeof(System.Int32));

           dt.Columns.Add("SortLevel", typeof(System.Int32));

           dt.Rows.Add(new object[] { 800, "Richard P. Joines", 0 , -1, 0});

           dt.Rows.Add(new object[] { 644, "Jimmy Yanzee", 1, 0, 1 });

           dt.Rows.Add(new object[] { 646, "Yiminey Zoo", 2, 0, 1 });

           dt.Rows.Add(new object[] { 234, "Lead Saunders", 3, 0, 1 });

           dt.Rows.Add(new object[] { 754, "Rick H. T.", 4, -1, 0 });

           dt.Rows.Add(new object[] { 754, "Nancy Red", 5, 4, 1 });

           dt.Rows.Add(new object[] { 346, "Earl Bwon", 6, 5, 2 });

           dt.Rows.Add(new object[] { 643, "Marvin K. Mooney", 7, 5, 2 });

           return dtsTemp;

       }

We then create a hierarchical dataset and initialize the grid:

 DataSet dtsTemp = new DataSet();

 transactionGrid1.DataSource = MakeTable(dtsTemp);

 transactionGrid1.TransactionTableName = "Clients";

this.DataSource = CreateHierarchicalDataSet(dtsTemp.Tables["Clients"] , 3);

Well, 8.3 is pretty old, so this could easily be a bug that has been fixed along the way. But like I said, there are also so cases where the grid simply cannot handle this because of the complexity of the RowLayouts.

If you can post a small sample project demonstrating the issue, I'd be happy to take a look and try it in the latest version to see if the issue still occurs.
