Evaluate the RadGridView to support the functional requirement

Hi,

I have a requirement and need to evaluate if RadGridView can support this.

I need to display hierarchical data in the grid. The data can span unto 4 levels. To clarify it further, say I have Manufacturer, Retailer and consumer. Here the consumer can directly purchase from a manufacturer. Or he can consume from a retailer. Also retailer can purchase from the manufacturer. I am interested in showing up the data in a user friendly format. I have tried these 2 options

1. Group by feature and realized that even when the consumer purchases directly from Manufacturer, the data for the consumer is displayed at 3rd level. Since the data is grouped on Manufacturer and then the Retailer. So here the consumer is shown as Manufacturer1-> Retailer (EMPTY)-> Consumer.
2. The other option was showing the data establishing relationship between tables. This served the purpose but the view is unfriendly. The user has to scroll up and down too much to view the data.

Please let me know if there is a possibility with RadGridView to support this requirement. To summarize it, I need to display data hierarch ally where I have Manufacturer, Retailer and Consumer. The Consumer can purchase from both Retailer and Manufacturer. And Retailer can buy only from Manufacturer. So the hierarchy can be

-Manufacturer1
    -Retailer1
        -Consumer2
        -Consumer3
    -Consumer1
-Manufactuer2
    -Consumer4
    -Retailer2
        -Consumer5
    Retailer2

RadButtonElement text disappears when form minimised

RadButtonElement text disappears after window is restored from minimised state (to system tray).

Attachment 01 shows state prior to minimising.

Attachment 02 shows state after restoring from minimised state.

Only this RibbonTab is affected (not Windows, or Create).

If another tab is selected, then window is minimised, and restored, text re-appears on Task List tab.

If window is minimised and restored without selecting another tab, text still does not appear.

Tried calling RepaintElements(). No change in behaviour.

Can't edit contents of a GridViewLookUpColumn

Forgive the cross-post, but I didn't realize until afterwards that GridViewLookUpColumn should be asked here instead.
I have a GridView that has three columns. The first is read only and named RuleKeyGuid. The second is called RuleKey, and the last is called KeyValue. I'd like for the second column to be a drop-down that suggests what the user might be looking for based on a data source. Here's what I entered:

    
            System.Collections.IDictionaryEnumerator iterator = sortedRuleKeys.GetEnumerator();

            while (iterator.MoveNext())

            {

                GridViewRowInfo rowInfo = radGridView_RuleKeys.Rows.AddNew();

                rowInfo.Cells[0].Value = ((RuleKey)iterator.Value).RuleKeyGuid.ToString();

                rowInfo.Cells[1].Value = ((RuleKey)iterator.Value).keyName;

                rowInfo.Cells[2].Value = ((RuleKey)iterator.Value).keyValue;

            }

            ((GridViewLookUpColumn)radGridView_RuleKeys.Columns[1]).AutoCompleteMode = AutoCompleteMode.SuggestAppend; 
        
            ((GridViewLookUpColumn)radGridView_RuleKeys.Columns[1]).DropDownStyle = RadDropDownStyle.DropDown; 
        
            DataTable dt = new DataTable(); 
        
            dt.Columns.Add("RuleKey", typeof(string)); 
        
            dt.Rows.Add("Mobile"); 
        
            dt.Rows.Add("Business"); 
        
            dt.Rows.Add("Fax"); 
        
            ((GridViewLookUpColumn)radGridView_RuleKeys.Columns[1]).DataSource = dt;

If I make changes in the grid to cells in the third column, it works just fine. But I can't change the second column. When I type, it seems to be accepting whatever I'm typing, but when I hit enter, it goes away.

I have two problems here.
1) The value that I've manually set the cell to doesn't show up unless it's a member of the DataSource.
2) The user cannot enter any value other than what is in the DataSource. If they type something in, it doesn't "stick". You hit Enter and the value reverts to whatever it was before.

How do I go about addressing this? They both seem to be related. Is there a setting I'm missing or am I approaching this problem incorrectly?

Fixed splitter on tool window

Hello,

I have a tool window in a Rad Dock on a form. I've set the Allowed Dock states so it can only be docked or hidden, but I also want to ensure that apart from this, it cannot grow or shrink (like having a fixed splitter). Is there a way to do this please?

Thanks

Richard

Drag and drop to/from multiple grids

Using the the example in this link I am trying to figure the best way to drop a row only on the specific grid you want to add it to.

For example, I have 4 grids in a docking panel. lets call them grids1 - grid4. grid1 and grid2 has values I want to share with grid2. grids 3 and grid4 do not except any drop. However, what is happening is that when I drag from grid1 to grid4 it addes the value to grid2. How can I tell if the grid I am hovering over is the grid that I want to add the value to.

Thanks
Stephen

Refreshing GridView after Insert

I have a gridview that uses outside controls to insert/update/delete rows.

I fill it with a tableadapter.

    
                    private void ManageLocations_Load(object sender, EventArgs e) 
        
                    { 
        
                        this.wISE_LocationsTableAdapter.Fill(this.locations.WISE_Locations); 
        
                    }

I insert/update/delete using custom calls. The following works fine -- it inserts fine and grid refreshes with inserted record -- but when I close the child form in which it is called, and then reopen the child form, the grid is missing the new record.

    
                    private void InsertLoc() 
        
                    { 
        
                        sh.InsertLoc(txtName.Text, txtZip.Text, string.Empty, string.Empty); 
        
                        this.rgLocations.Rows.Add(txtName.Text, txtZip.Text); 
        
                        this.UpdatePanelInfo(this.rgLocations.CurrentRow); 
        
                    }

The same thing with the update and delete. It is like the tableadapter isn't refreshing with the new data.

I am using a SQLCE db, and that db is in my bin folder.

Any ideas on how I can refresh the tableadapter so that the grid always reflects exactly what is in the db?

Thanks

Chad
