Custom

[Andrew Rosenblum]

A GridDataControl is bound to an ObservableDataCollection. No columns are defined in xaml.

Data looks like:
Book ABC DEF
Price 1.2345 1.4567
Change .03 .04

So the price is a decimal which should be formatted one way and the 'change' is a percent which should be formatted a different way. A column would contain multiple types.

What would be an easy way to do this?

I would like to make them custom types MyDecimal and MyPercent. Then create 2 IValueConverters.

If common is my namespace, converters are declared in xaml:



What is the xaml to the converters to the types in a GridDataControl? A full xaml file is attached.

Hi Andrew,

We have analyzed your requirements and this can done by using ValueConverter property in VisibleColumn. Also we have prepared a sample based on this and please find the sample under the following location.

Can DataTemplates be set in the xaml without defining Visible Columns in the xaml?

In the attached code, the xaml file defines Visible Columns.

In the thread DataTemplateSelector, the c# delegate sets the data template:
private static void ModelQueryCellInfo(object sender_, GridQueryCellInfoEventArgs e_)
{
if (e_.Style.CellValue is IDecimalNumber)
{
e_.Style.CellType = "DataBoundTemplate";
e_.Style.CellItemTemplateKey = e_.Style.CellValue.GetType().Name + "Template";
}
}

The delegate would set a cell with an object of type NoDecimalNumber (which extends IDecimalNumber) to the NoDecimalNumberTemplate.

Can NoDecimalNumber be assigned to NoDecimalNumberTemplate in xaml?

Hi Andrew,

We have analyzed your requirements and this can done by using ItemTemplate. Also we have prepared a sample based on this and please find the sample under the following location.

Can the DataTemplate be assigned in xaml? We don't want to use code like the QueryCellInfo delegate.

Hi Andrew,

It is not possible to set the DataTemplate in XAML when VisibleColumns are not in XAML. DataTemplates can be assigned specific to columns only and not to Grid.

Please let us know if you have any questions.

Thanks,
