Row with id '30' already appears in the hierarchy with parent id '27'. Each row in a self-reference hierarchy can appear only once in the hierarchy

Having more than one dock using embedded forms

Morning,

I'm trying to embed a form that has a RadDock into my main application RadDock. The idea is that an end user would search for a project and the project would be loaded into the main forms RadDock (rdkMain). This would allow for more than one project to be shown at any given time. The project form could have multiple vendors which each would be loaded into the project RadDock(rdkProject). I understand that windows will only allow for a single form to be set to IsMdiContainer. Is there any way of doing this?

Thanks,

James

RadGridView with group/summary rows only on bottom

Hi,

I have a GridView where I'm adding a grouping, and then summarizing some values for each group. I'm trying to get the grouping / summary rows to ONLY show at the bottom of each group. It seems that by default when adding a group that a group row always shows up at the top of each group. Here is a snippet of my code:

GridGroupByExpression groupExprCol1 = new GridGroupByExpression("col_1 Group By col_1");

grid1.GroupDescriptors.Add(groupExprCol1);

GridViewSummaryItem

sumItemValue = new GridViewSummaryItem("value", "{0,12:#,0;(#,0)}"

    GridAggregateFunction.Sum);

GridViewSummaryRowItem sumGroupCol1 =

new

GridViewSummaryRowItem();

sumGroupCol1.Add(sumItemValue);

grid1.MasterTemplate.SummaryRowsBottom.Add(sumGroupCol1);

The end result that I'm trying to achieve would look similar to this:

Col 1	Col 2	Value
AA	Yes	1
AA	No	2
AA	No	2
AA	Yes	5
Total AA:		10
BB	No	3
BB	No	2
Total BB:		5
CC	Yes	4
Total CC:		4

So basically I'm trying to avoid displaying a group header row at the top of each group, and just show a summary row at that bottom of each group. Any help would be greatly appreciated. Thanks.

GridViewImageColumn.IsVisible = READONLY?

Either this is a bug or I'm doing something really, really silly! My money's on the 2nd option :)

I have a grid with a GridViewImageColumn that I have to set .IsVisible = False.

No matter what I do, it flips back to 'True'

What am I doing wrong?

BTW - This happens both at-runtime (dynamically setting the IsVisible property for this column = False does nothing) AND it happens at design time: You can load up the grid, select the Columns property, select the GridViewImageColumn and try changing IsVisible from True to False. Doesn't work :(

Any help would be very much appreciated!

RadRibbonForm title text getting cut off

Sometimes when we set the text of the RadRibbonForm it gets cut off and has "..." added to the end. It's not consistent though, that's what it making it hard to diagnose. It also doesn't seem to matter how many characters long the text is - the last 10-15 pixels of the text gets replaced with "...".

Is there any property that can be set to change this behavior so that all of the text always shows on the title bar?

Border in template

Hi,

I'm working with a RadGridView and add a Template on it with :

GridViewRelation relation = new GridViewRelation(gridView.MasterTemplate, template);

Then I'm trying to customize the view of my gridview because I would like delete all borders on my Template.

I'm trying to do that but it's not enough to delete all borders. What I could do more ?

private void gridView_ViewCellFormatting(object sender, CellFormattingEventArgs e)

{

GridDetailViewCellElement childCell = e.CellElement as GridDetailViewCellElement;

GridGroupExpanderCellElement expanderCell = e.CellElement as GridGroupExpanderCellElement;

if (e.CellElement.ViewTemplate.Parent != null)

{

e.CellElement.BorderBoxStyle = BorderBoxStyle.SingleBorder;

e.CellElement.BorderWidth = 0;

e.CellElement.Padding = new Padding(0);

}

else if (childCell != null)

{

childCell.BorderBoxStyle = BorderBoxStyle.SingleBorder;

childCell.BorderWidth = 0;

childCell.Padding = new Padding(0);

childCell.PageViewElement.Header.Visibility = ElementVisibility.Collapsed;

childCell.GridViewElement.DrawBorder = false;

childCell.GridViewElement.GroupPanelElement.DrawBorder = false;

RadPageViewStripElement stripElement = childCell.PageViewElement as RadPageViewStripElement;

if (stripElement != null)

{

stripElement.DrawBorder = false;

stripElement.BorderBoxStyle = BorderBoxStyle.SingleBorder;

stripElement.BorderWidth = 0;

foreach (RadPageViewItem item in stripElement.Items)

{

item.MaxSize = new Size(0, 1);

item.Visibility = ElementVisibility.Hidden;

}

Thanks for your help,

Simon

RadLabel AutoSize and Refresh

I am using a RadLabel to show the status and results of a process that builds the data for a GridView. Click a button to start that process and the text set to "Please wait while your list is being built..." then I do a refresh() on that control. At the end of that process the text is set to "Row Count: xxx".

Even though I have the label set to autosize, the full text ("Please wait while....") is cut off at the length of whatever the text was at the beginning of the process. My current workaround is to make this autosize = false and pad the text with enough trailing blanks so that it is always longer than "Please wait while your list is being built...".

I replaced that RadLabel with a Microsoft Label and that works fine.

Is that a bug with that RadLabel?
