It was the data in the dataset, I had some records that had '\0' in a char(1) column, and the grid paging would just not work with those records in the dataset. It would do the post back, but not update the grid after the response, it would just stay on the first page and not throw any errors.

Hello ,

Do you use AutoGenerated columns or you manually declare the columns in the markup?

Hope hearing from you

The columns are declared in the markup.

Hello,

Thank you for the update.

I am glad that you have succeeded to solve the issue.

I didn't test that, I just fixed the bug, so the null characters weren't being inserted into the db.

Hello,

Were you able to solve the issue by setting datatype and AllowNull properties_

Hope hearing from you.

I'm guessing it is because the column definition we have is like this, missing the datatype and AllowNull:

<igtbl:UltraGridColumn BaseColumnName="C/D" Key="C/D" Width="40">

<CellStyle HorizontalAlign="Center"></CellStyle>

<Header Caption="C/D">

<RowLayoutColumnInfo OriginX="9" />

</Header>

<Footer>

<RowLayoutColumnInfo OriginX="9" />

</Footer>

</igtbl:UltraGridColumn>

Hello asanders0001,

Thank you for tha clarification.

As you  have null values ('\0') in the column I used the following declaration ot the column :

<igtbl:UltraGridColumn BaseColumnName="CharColumn" DataType="System.Char" AllowUpdate="Yes"

                            IsBound="false"  AllowNull="true"  >

                            <Header>

                                <RowLayoutColumnInfo OriginX="2"></RowLayoutColumnInfo>

                            </Header>

                            <Footer>

                                <RowLayoutColumnInfo OriginX="2"></RowLayoutColumnInfo>

                            </Footer>

                        </igtbl:UltraGridColumn>

DataColumn column = new DataColumn();

        column.DataType = System.Type.GetType("System.Char");

        column.ColumnName = "CharColumn";

        column.AutoIncrement = false;

        column.Caption = "CharColumn";

        column.ReadOnly = false;

        column.Unique = false;

        table.Columns.Add(column);

for (int i = 0; i <= 20; i++)

        {

            row = table.NewRow();

            row["RowNum"] = i;

            row["DisplayValue"] = "DisplayValue " + i;

            row["CharColumn"] =  '\0';           

            table.Rows.Add(row);

        }

And I was not able to reproduce the issue.

Can you please modify my sample code in order to encounter the behavior?

Hope hearing from you.
