[Solved] Add a Column to an existing DetailTable via the code behind

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 ?????

[Solved] LoadingPanel Issue

Hello,

I have one problem regarding changing the Index of the Dropdownlist.

I have one Asp:Dropdownlist. And on the change of the Index of the dropdownlist, I am using Rad - Loading Panel. And according the field selected from the dropdownlist, my other controls like Textbox, Radiobutton & Date Pickers are being visible and Invisible.

But the prolem is the loading panel is seen along with the control which is already seen right now.

My requirement is when I change the value in the dropdownlist, the loading panel only should be visible and after the loading panel disappers, the controls should appear. How can I do this.

... did not implement ICallbackEventHandler message

Hi,

Just upgraded to the Premium Suite for some Xmas development work.

I have created a server-side control that renders a TreeView whose nodes are set to be populated on Callback.

On expanding the first node, I have the following error message popping up:

The target 'ctl00$ctl01$mainContentArea$treeNavigation$kbTreeView' for the callback could not be found or did not implement ICallbackEventHandler.

My server-side control is below:

                                                childTreeNode.Nodes.Add(childTreeNode);                                  
                                            }         
                                }

The serverside control KnwoeldgeBaseTree (represented by the class above) is within the Page as usual:

<KB:KnowledgeBaseTree id="knowledgeBaseTree" runat="server" />

So, as far as I know, I'm in the right place as far as the page lifecycle is concerned.

I've also tried rendering the tree in the Init stage of the server control. No change.

Can you please help me fix this?

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.

GridTableView tableSubLocation = new GridTableView(rdgLocation);

rdgLocation.MasterTableView.DetailTables.Add(tableSubLocation);

tableSubLocation.DataSource = dsData;

Add items to Grid on Load

How do you add items on load with the RadGrid?

There will always be the same few items added on data entry every time, but of course they could change sometimes, so I would like to add them to the grid, and then put the grid in edit mode.

Thanks,

Brett
