Hi Team,
1. I want to have a placeholder in the row that appears in xamdatagrid when the property AllowAddNew=True. Please refer to the sample image. We had this feature in xamgrid as shown in the image.
I want the same feature where I can have a different placeholder for every field. For example for the field SKU - the placeholder should be "Enter SKU", for Name- the placeholder should be "Enter Name".
2. Secondly, how I can customize or modify the expansion button which is shown in front of a row?
How can I put a text or another image instead of this "+" and "-" symbol?
Thanks.
Hello Vivek,
I have been investigating into the behavior you are looking to achieve and I have some information for you. I will answer your inquiries in the order they were asked.
1. The placeholder does not exist in the XamDataGrid in the same way as in the XamGrid – the placeholder for the XamDataGrid must match the data type of the column as the placeholder will be the initial value of the cell.
The route to having a placeholder value in the Add New Record is to handle the InitializeTemplateAddRecord event of the grid. The event arguments of that event can net you the TemplateAddRecord, which you can then add a value to the Cells of. For example:
private void XamDataGrid_InitializeTemplateAddRecord(object sender, Infragistics.Windows.DataPresenter.Events.InitializeTemplateAddRecordEventArgs e) { DataRecord record = e.TemplateAddRecord; record.Cells[0].Value = 1; }
2. The expansion indicator can be modified by re-templating the ExpansionIndicator element. The default template of the ExpansionIndicator can be found in the PrimitivesGeneric_Express.xaml file commonly found at the following directory with Infragistics controls installed:
C:\Program Files (x86)\Infragistics\<version>\WPF\DefaultStyles\Windows\PrimitivesGeneric_Express.xaml
Please let me know if you have any other questions or concerns on this matter.
Hi Andrew,
Thanks for the suggestions, how can I style the placeholder for the foreground, font, etc? Also, currently, it is showing as a value in the cell area when the user clicks in the cell it needs to be removed first so that the respective value can be entered by the user, I want that the placeholder should act as empty text in Combobox so that when the user clicks in the cell the placeholder should disappear and when users click outside the cell it should be visible. How to achieve both these functionalities?
I have put together a sample project that uses an alternative route to achieve this requirement by re-templating the CellValuePresenter element and using a custom-derived Field for the styling.
In the attached sample, the relevant code for achieving this is in the CVPStyleDictionary with an added TextBlock named “addNewPlaceholder.” There is also an added MultiDataTrigger in the ControlTemplate.Triggers for binding to the AddNewRecord to set the Visibility of the TextBlock and ensure that the value of the cell is null to show it again as it will not show in edit mode.
I hope this helps you. Please let me know if you have any other questions or concerns on this matter.
