i would like to develop a hierarchical grid view programmatically. The firstrow(masterTableview) im adding it at design time.
Im doing that using the code below, but its not adding the griddesignview(children for the first row) Does anyone see whats wrong with the code im using here:
Master.ParentlocationID is matched to TableView.LocationID, im also using a dataset as my datasource.

 

adapter.Fill(dsData);

 

 

 

 

 

GridTableView tableSubLocation = new GridTableView(rdgLocation);

 

rdgLocation.MasterTableView.DetailTables.Add(tableSubLocation);

tableSubLocation.DataSource = dsData;

 

 

 

 

 

tableSubLocation.Width =

 

 

 

 

Unit.Percentage(100);

 

 

 

 

 

 

GridRelationFields relationFields = new GridRelationFields();

 

tableSubLocation.ParentTableRelation.Add(relationFields);

relationFields.MasterKeyField =

 

 

 

 

"LocationID";

 

relationFields.DetailKeyField =

 

 

 

 

"ParentLocationID";

 

 

 

 

 

 

GridBoundColumn boundColumn;

 

boundColumn =

 

 

 

 

new GridBoundColumn();

 

tableSubLocation.Columns.Add(boundColumn);

boundColumn.DataField =

 

 

 

 

"LocationID";

 

boundColumn.HeaderText =

 

 

 

 

"LocationID";

 

boundColumn =

 

 

 

 

new GridBoundColumn();

 

tableSubLocation.Columns.Add(boundColumn);

boundColumn.DataField =

 

 

 

 

"Location";

 

boundColumn.HeaderText =

 

 

 

 

"Location";

Hi Omlac,

"RadGrid does not support mixing declarative grid columns with grid columns added dynamically at runtime. You should either create all the columns in the grid programmatically, or else define them all in the ASPX file."

Check out the link below for more information on programmatic creation of hierarchial grid.

Thanks,
Princy

Hello,

and what if I want to programmatic add a new column to an existing Detail Table?

something like that.

<MasterTableView> 
   <detailtables> 
        <Gridtableview> 
 
            <columns> 
              <gridboundcolumn></gridboundcolumn
              <gridboundcolumn></gridboundcolumn
              <gridboundcolumn></gridboundcolumn
 
                How to insert more columns here, using the code behind? 
 
            <columns> 
        <gridtableview> 
 
   </detailtables> 
 
<columns>......</columns> 
<MastertableView> 

I used this successfully to add to the master table, but I cant add to the detail table.

                GridBoundColumn boundColumn; 
                boundColumn = new GridBoundColumn(); 
                RadGrid1.MasterTableView.Columns.Add(boundColumn); 
                boundColumn.DataField = "valor"
                boundColumn.HeaderText = "Valor"
                boundColumn.UniqueName = "valor"
                boundColumn.DataFormatString = "{0:R$###,###.##}"
How can I do the same with DETAILTABLES ?????

Thanxs
