Hi even I face the same issue. I use an Unboundcheckbox column. When I click any checkbox, the state of other checkboxes changes to "Partial" eventhough I had explicity set the mode as "bi-state" in the behaviour. My Infragistic version is: 11.2.20112.2055

 <ig:GEWebDataGrid ID="gridIJE" runat="server" FunctionalityCode="IJE_InvoiceJournalEntry" VisibleControl="True" Width="100%" StyleSetName="Office2007Blue" DisableControl="False" AutoGenerateColumns="False" ViewStateMode="Enabled" DataKeyFields ="RowID" EnableDataViewState="True" EnableAjax="False"> 

<Columns>

<ig:UnboundCheckBoxField HeaderChecked="False" Key="UnboundCheckBoxField_0">

<Header Text=""></Header> </ig:UnboundCheckBoxField>

Hello Yady,

Please let me know if you have any further questions regarding this issue. Did you manage to resolve it?

Hi,Sorry for the late response.I was occupied with my project tasks. My answer to your question is that i still face this issue. On initial page load my web data grid shows checkedbox column as bistate. When,  i clear the datasource of the Datagrid, and rebind the data again to it, i notice that the checkedbox column now shows as tristate. I use the below code to clear the data from the grid and to bind the data again to it.

 this.RolesDataGrid.ClearDataSource();
 this.RolesDataGrid.DataBind();
 this.RolesDataGrid.DataSource = LogicSEMaster.GetAllRoleDetails();
this.RolesDataGrid.DataBind();

RolesDataGrid is the webdata grid. I am using Infragistics v11.2 on my machine.

Let me know if i need to provide you with more info on this.

Thanks

Hi,

When you call ClearDataSource, you actually clear out all unbound values from the grid since it is assumed you are giving a new data source.

Hello,

Please let me know if David's notes hepled you to resolve the issue.

Hi Team,

                 I understand what ClearDataSource does, but is it related to the tristate checkbox column? I dont understand as to why the unboundcheckbox column shows as tristate when i cleardatasource and bind the data again. However, on the first page load it shows as bistate checkbox column.
