Hi,

I need to implement several level nested hierarchy with possibility to check (or select) multiple rows, but also whole groups or sub-groups of rows (let say that for rows of orders for customers from different countries I need to group every orders of each customer together and every customers from each country together and then be able to select multiple orders – one by one or every for selected customers or every for selected country – so that after selecting one subgroup, each row of this sub-group will be selected).

I would like to use grouping for this – but I was not able to simply add check-boxes in header lines.

<telerik:GridGroupByExpression>

<telerik:GridGroupByField FieldName="countryName" HeaderText=" <input type='checkbox' onClick='CountryRowSelecting()'> " />

</SelectFields>

<telerik:GridGroupByField FieldName="countryId" SortOrder="Descending" HeaderText="Country" />

</GroupByFields>

</telerik:GridGroupByExpression>

<telerik:GridGroupByExpression>

<telerik:GridGroupByField FieldName="customerName" HeaderText=" <input type='checkbox' onClick='CustomerRowSelecting()'> " />

</SelectFields>

<telerik:GridGroupByField FieldName="customerId" SortOrder="Descending" HeaderText="Customer" />

</GroupByFields>

</telerik:GridGroupByExpression>

But then I was not able to properly handle these events, I think there should be some easier way.

I was also trying hierarchical grid (but I would like it with grouping more), but there with multi-rows grouping, when I selected whole category, just one sub-level subcategories was selected (but I need it for each level- e.g. after selecting some country, each order for each customer from this country would be selected).

Does radgrid somehow enable this desired behaving?

Thanks

Jan

Hi jan,

The functionality can most easily be achieved in a hierachical structure. As a starting point, you can use the following example, which shows how to access the different elements of the hierarchy. A similar approach can be used to achieve the effect of selecting the inner level(s) by selecting the master record. Also, attached to this message, is a small working application, which handles a very similar functionality.
I hope this helps.

Hello Le,

You would have to add seperate expressions to your GroupByExpressions collection to achieve the required. Check out the code below :

c#:

                            //First expression          
                    GridGroupByExpression expression1 = new GridGroupByExpression();          
                    GridGroupByField gridGroupByField1 = new GridGroupByField();            
                            
                    gridGroupByField1 = new GridGroupByField();          
                    gridGroupByField1.FieldName = "FirstName";          
                    gridGroupByField1.HeaderText = "FirstName";                  
                    gridGroupByField1.FormatString = "<strong>{0}</strong>";                  
                    expression1.SelectFields.Add(gridGroupByField1);          
                              
                    gridGroupByField1 = new GridGroupByField();          
                    gridGroupByField1.FieldName = "FirstName";          
                    expression1.GroupByFields.Add(gridGroupByField1);          
                      
                    //Second expression          
                    GridGroupByExpression expression2 = new GridGroupByExpression();          
                    GridGroupByField gridGroupByField3 = new GridGroupByField();          
                             
                    gridGroupByField3 = new GridGroupByField();          
                    gridGroupByField3.FieldName = "PlaceFrom";          
                    gridGroupByField3.HeaderText = "PlaceFrom";                 
                    gridGroupByField3.FormatString = "<strong>{0}</strong>";          
                    expression2.SelectFields.Add(gridGroupByField3);                  
                              
                    gridGroupByField3 = new GridGroupByField();          
                    gridGroupByField3.FieldName = "PlaceFrom";          
                    expression2.GroupByFields.Add(gridGroupByField3);          
                    // Add the expressions to the GroupByExpressions collection          
                    RadGrid1.MasterTableView.GroupByExpressions.Add(expression1);          
                    RadGrid1.MasterTableView.GroupByExpressions.Add(expression2);          

Thanks
