FieldName property of GridViewDecimalColumn does not like a string with two underscores

Hi,

I'm creating a GridViewDecimalColumn as follows:

GridViewDecimalColumn col = new GridViewDecimalColumn();

col.Name = node.Name;

col.FielName = node.Name;

col.HeaderText = friendlyName;

When setting the FieldName property, if node.Name = tb_Column then everything is fine. However, when node.Name = tb_Column_1 then I get a FormatException - Input string was not in a correct format.

Do I need to format that FieldName property in any special way or something?

Thanks

ExcelExportFormatString on GridViewDateTimeColumn does nothing

Ok,

Yet again, another issue that I am facing with the GridView control... :-)

Here are the steps for creating and populating my grid:

1. I construct my columns (mostly, GridViewTextBoxColumn, GridViewComboBoxColumn, GridViewDecimalColumn and GridViewDateTimeColumn) programmatically on form load. First of all, I construct these columns using xml data for the Fieldname properties etc.

Here is an example:

foreach (XmlNode mapNode in mappingXmlDoc.SelectSingeNode("Mappings"))

{

// Maps to GridViewDateTimeColumn

if (elementPrefix == "dt")

{

GridViewDateTimeColumn col = new GridViewDateTimeColumn();

col.Name = mapNode.Name;

col.FieldName = mapNode.Name;

col.HeaderText = friendlyName;

radGridView1.Columns.Add(col);

}

2. After I constructed these columns, I go ahead and initialize the grid by assigning it a datasource. The DataSet in turn is populated with xml data:

DataSet dsData = new DataSet();

dsData.ReadXml(xmlFile);

radGridView.DataSource = dsData.Tables[0];

The xml data that I read into the DataSet looks like this:

<assets>

<asset>

<tb_Desc></tb_Desc>

<dt_MoveDate><dt_MoveDate>

</asset>

</assets>

3. When setting following properties on the GridViewDateTimeColumn as follows:

foreach (GridViewDataColumn in radGridView1.Columns)

{

string[] strArr = col.FieldName.Split(new char[] {'_'});

// This way I know its a GridViewDateTimeColumn

if (strArr[0] == "dt")

{

((GridViewDateTimeColumn)col).ExcelExportType = DisplayFormatType.Custom;

((GridViewDateTimeColumn)col).ExcelExportFormatString = "dd.mm.YYYY";

((GridViewDateTimeColumn)col).FormatString = "{0:dd.mm.YYYY}";

}

nothing happens... I've tried to set the properties both before and after I set the gridview's datasource with no success.

Also, I'm using the ExportToExcelML class for exporting and I always end up with data for the date field looking like this: 1/27/2011 12:00:00 AM in both the grid and exported excel spreadsheet which is wrong.

Is there anything I'm doing wrong somewhere?

I appreciate your help.

Thanks

RadDateTimeEditor defaults to 1 Jan 1753

Hi,

Any idea why my RadDateTimeEditor columns always defaults to 1 Jan 1753 on selection?

I've looked at the properties that RadDateTimeEditor expose but can find anything relevant.

Is there a why to default it to DateTime.Now maybe?

Thanks

Appointment, Resources, AppointmentResources and INSERT issue with Identity

I am struggling with databinding the RadScheduler.
I have the tables created, the constraints/relationships set up just fine.
When I assign a resource to an existing appointment, the row is added to the AppointmentResource relationship table just fine into the database.

However, when I try to assign a resource to a new appointment, I get a constraint error.
When I remove the constraints, I see values like -4 in the AppointmentId column in the AppointmentResource table.
So, I'm assuming that, since the AppointmentId in the Appointment table is set to IDENTITY, the code that handles the relationships doesn't know the AppointmentId yet when creating the rows to add to the AppointmentResource table.
Is anyone aware of this, and do you have a workaround? I'm thinking the only workaround is to bind to objects and do the database code myself..

Document name highlighting in docking manager.

Hi all,
I have a docking manager in my project which all the tabs are populated and they can be closed whenever needed. My issue is that, the CURRENT TABS name should be bold and the names of the remaining tabs should not be so. I am using the dockingmanager_tabchanging to do this, but the problem is that i am not able to undo the changes to the style to the previous tab. So if I have 3 tabs open and I click on one tab, the font changes to bold, now when I click on the next tab the previous TAB'S bold style needs to go away. How can I do this? Can I get a count of the tabs in the docking manager and undo all the styles or something like that I could not do it. Any help would be greatly appreciated.

Private Sub dockingManager_DockTabChanged(ByVal sender As Object, ByVal e AsTelerik.WinControls.Docking.DockTabChangedEventArgs) HandlesdockingManager.DockTabChanged

In this event e.Tab.Text just gives the changed tab text.
Is there any way we can change the text style of all the tabs that are open. Probably some where deep down the object structure. Again any help would be great.

End If

Thanks

Filterbox suddenly loses its textbox while typing?

I have a very irritating problem with RadGridView. Look at the video: Filter box suddenly becomes Non-Editable by itself

I am using Q1 2008 SP1. The filter it seems has suddenly become non-editable, at least from the way the textbox vanishes, but if I press on any key like 'd' or 's' or 'q' then this same filter box will show up its filter textbox.

Anyone knows how to get rid of this 'weird' problem?

Thanks
Sunil

Textbox backcolour

Hi,

I am new to radControls so this will most likely be something simple.

I have a textbox which I would like to change the backcolour but when I change the backcolour in the properties, nothing changes.

What am I missing?

Thanks
