I cant get the summary row to show in my grid. This is the code I have for setting upo summary row
GridViewSummaryRowItem totals = new GridViewSummaryRowItem();
totals.Add(
new GridViewSummaryItem("Total", "{0}", GridAggregateFunction.Sum));
this.radGridView1.MasterGridViewTemplate.SummaryRowsBottom.Add(totals);
Am i missing something? Are there more properties i need to be setting on the grid or column or master view for the summary row to show ?
Thanks

Hello, Ive been testing some of your controls and I love them, they are awesome. But Iam having a problem with the RadRibbonBar control. I cant find how to change a chunks border color. It seems like this should be really easy but I cant find how to do it anywhere. Ive tried using the theme builder but it seems like the designer stops just short of having the chunks in it. The theme builder stops at ExpandableStackLayout with nothing below it in the tree and if I use Edit UI Elements thats where all of the chunks properties are located. Now if try to use Edit UI Elements to try to change the chunks properties it only changes the "add new group" border color in Visual Studio's designer not any of the existing chunks border colors. I have also tried changing the color through code but I cant find a border color property anywhere. I know this has to be possible because the different themes the control comes with have different color borders on their chunks. Can you please point me in the right direction with a bit of sample code. I'm probably going to feel really stupid when you show me.... probably right in front of my face. Thanks for the help and for a great product.

I'm finding that if I call BestFitColumns, the column widths are set to one pixel. I'm guessing this is happening because I call it too early, before the columns have been filled with data. Can you suggest a good time to call this method? Also, is it possible to combine the best fit behavior and still make one of the columns be "stretchy" -- i.e. take up the remaining space? My goal is that all but one of the columns would size to their content, and that the remaining column would stretch to consume the remaining space.

I'm wondering how I could catch the event when you click on the "delete row" in the default context menu.
What I want to do is when I click on that, it removes the row from one gridview and it has to be added to another gridview.
I was searching in the helpfiles but I didn't find anything that could help me.
thanks in advanced

An error occurs in the cellFormating event:
in the first databinding of gridview the error does not happen , but if I try a second databinding, for refresh the gridview,
the following error occurs:
in the first databinding of gridview the error does not happen , but if I try a second databinding, for refresh the gridview,
the following error occurs:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object.
at Telerik.WinControls.Primitives.TextPrimitive.MeasureOverride(SizeF availableSize)
The code where the error occurs is the folowing:
| private void gvPremios_CellFormatting(object sender, CellFormattingEventArgs e) |
| { |
| if (e.CellElement.ColumnInfo is GridViewDataColumn && !(e.CellElement.RowElement is GridTableHeaderRowElement)) |
| { |
| GridViewDataColumn column = (GridViewDataColumn)e.CellElement.ColumnInfo; |
| if (column.DataField == "MyColumn") |
| { |
| if (e.CellElement.Children.Count > 0) |
| return; |
| RadLabelElement element = new RadLabelElement(); |
| element.Text = "<html>This is a test..." |
| e.CellElement.Children.Add(element); |
| } |
| } |
The strange thing is in the "element.text" property, that if I not put the the tag "<html>"... the error does not happen, but, i need formating the field with a html code...
And the property "DisableHTMLRendering=false" is not working as it should, leaving the whole column unconfigured.

I've got something strange...
My third child, when having only 1 row, it's not showing the row.
I took a screenshot of it
http://picasaweb.google.com/gerbrand.adlogix/TelerikViewIssues?feat=directlink
I'm not doing anything special in my code to make the grid. I've got it only with one record. When I have more records, I get to see them.

I'm finding that the Grid doesn't use the font of its parent for the column headers and cells. Is there a way to cause it to do so?

Hey guys,
First and formost, this may not be an actual bug - there's a good chance I'm doing something a little bit abnormal.
I have a RadGridView (named gvwManifestLines) with these three columns:
| GridViewTextBoxColumn lengthColumn = new GridViewTextBoxColumn(); | |
| lengthColumn.UniqueName = "LengthColumn"; | |
| lengthColumn.HeaderText = "Length"; | |
| lengthColumn.DataType = typeof(Int32); | |
| lengthColumn.FieldName = "itemLength"; | |
| lengthColumn.FormatString = "{0}cm"; | |
| this.gvwManifestLines.Columns.Insert(i++, lengthColumn); | |
| GridViewTextBoxColumn widthColumn = new GridViewTextBoxColumn(); | |
| widthColumn.UniqueName = "WidthColumn"; | |
| widthColumn.HeaderText = "Width"; | |
| widthColumn.DataType = typeof(Int32); | |
| widthColumn.FieldName = "itemWidth"; | |
| widthColumn.FormatString = "{0}cm"; | |
| this.gvwManifestLines.Columns.Insert(i++, widthColumn); | |
| GridViewTextBoxColumn heightColumn = new GridViewTextBoxColumn(); | |
| heightColumn.UniqueName = "HeightColumn"; | |
| heightColumn.HeaderText = "Height"; | |
| heightColumn.DataType = typeof(Int32); | |
| heightColumn.FieldName = "itemHeight"; | |
| heightColumn.FormatString = "{0}cm"; | |
| this.gvwManifestLines.Columns.Insert(i++, heightColumn); |
I am handling that gridview's CellFormatting event as follows:
| private void gvwManifestLines_CellFormatting(object sender, CellFormattingEventArgs e) | |
| { | |
| GridViewCellInfo cellInfo = this.gvwManifestLines.Rows[e.CellElement.RowIndex].Cells[e.CellElement.ColumnIndex]; | |
| if (e.CellElement.ColumnIndex == this.gvwManifestLines.Columns["LengthColumn"].Index || | |
| e.CellElement.ColumnIndex == this.gvwManifestLines.Columns["WidthColumn"].Index || | |
| e.CellElement.ColumnIndex == this.gvwManifestLines.Columns["HeightColumn"].Index) | |
| { | |
| if (cellInfo.Value == null || | |
| cellInfo.Value is DBNull || | |
| (int)cellInfo.Value <= 0) | |
| { | |
| e.CellElement.FormatString = "n/a"; | |
| } | |
| } | |
| } |
Essentially, I am using the length, width, and height values to calculate the volume per line in the volume column (omitted). I am doing a calculation in the grid's CellEndEdit for the length, width, height, and volume columns that will allow the user to either a) fill in length, width, and height to calculate the volume, or b) just enter in the volume and have the length, width and height ignored.
My implementation for this is to treat a value of '0' in the length, width or height column as a signifier that the calculation should ignore those three fields. However, it is confusing to have 0cm * 0cm * 0cm = 1000cm^2, so in the case of 0cm I want the display format to show as 'n/a'. It has a nicer feel.
This all works fine. The only problem is that when I pass the mouse over a cell that contains an 'n/a', the cell reverts back to '0cm' again until I click somewhere in the grid. There's a good change that the user will be doing a lot of back-and-forth waiving of the mouse around in the app, and this just looks sloppy.
What I wanted to do was to move my code in the CellFormatting handler into a private method, and then recall this method from within the CellMouseMove event. However, I am unsure how to use the MouseEventArgs to extract the relevant cell's row and column index information from the grid.
Additionally, there could be a better solution to this problem - I'm all ears!
Essentially, this isn't mission critical. It can wait for a bit, so I'm not going to be too worried about tinkering my way to a solution. I figure I'd just post here and see what comes up.

By default TextPrimitive renders the '&' character as an underscore on the following character, like a menu hotkey. I need to actually display an ampersand on the screen. I found that if I double the character ("&&"), the TextPrimitive displays the ampersand. However, it no longer sizes properly to the text it contains. I'm wondering if the TextPrimitive sizing code thinks the ampersands will cause underlines even though the rendering code draws an ampersand.

i currently loop through a month view to find out if certain cells have been selected
i need to expand upon this, and check if any appointments already exist on a selected cell but cant seem to find any property or method within the cell item that will allow me to check this.
any help is greatly appreciated.
Cheers,
Craig
