Hi David,
We have analyzed your reported issue and it is due to set Width as “0” for first and second columns. If you want to hide specific columns, we can use a column property “Visible” as false. Make sure that we can’t hide “TreeColumnIndex” column.
<ej:TreeGrid runat="server" ID="TreeGrid" TreeColumnIndex="2" BeginEdit="beginEdit" EndEdit="EndEdit" Height="100%" >
<Columns>
<ej:TreeGridColumn HeaderText="PhilipsID" Field="ID" Visible="false" />
<ej:TreeGridColumn HeaderText="PhilipsMatrixDataID" Field="DataID" AllowFiltering="false" Visible="false" />
<ej:TreeGridColumn HeaderText="Vendor" Field="Vendor" EditType="Dropdown" />
<ej:TreeGridColumn HeaderText="Model" Field="Model" EditType="Dropdown" />
<ej:TreeGridColumn HeaderText="Software" Field="Software" EditType="Dropdown" />
<ej:TreeGridColumn HeaderText="Ϭ" Field="DataElement" EditType="Dropdown" />
<ValidationRule>
//....
</ValidationRule>
</Columns>
</ej:TreeGrid> |
Please let us know, if you need any other assistance on this.
