How To Use DataTriggers In Silverlight DataGrid

In a Silverlight page I have a datagrid (items loaded from a SP list) and below it a dataform that lets the user make edits to the items displayed in the datagrid when a row is selected from the datagrid.  However, when a user makes an edit to an item using the dataform, the datagrid doesn’t get refreshed when I re-query (via CAML) the SP list to refresh the datagrid.  Only if I change another item in the dataform, does the datagrid then refresh as expected. Code when I Edit the list item in the dataform: public void EndEdit() { ClientContext context = new ClientContext(ApplicationContext.Current.Url); context.Load(context.Web); _skills = context.Web.Lists.GetByTitle("Skills_NewRequest").GetItemById(skillId); _skills["TimeStamp"] = TimeStamp; _skills["Parent"] = Parent; _skills.Update(); context.ExecuteQueryAsync(OnRequestSucceeded, OnFailListener); } private void OnRequestSucceeded(Object sender, ClientRequestSucceededEventArgs args) { Deployment.Current.Dispatcher.BeginInvoke(BindData); } private void BindData() { //MessageBox.Show("Your request has been submitted!"); }   And here’s the code for refreshing the datagrid: private void dataFormNewPending_EditEnding(object sender, DataFormEditEn

I tried to delete more than one row in datagird in silverlight, using chechbox checked, and binding to itemsource. I have following code: ---------------------- Orderlist = (System.Collections.ObjectModel.ObservableCollection<SilverlightWebService.Order>)dgOrders.ItemsSource;  System.Collections.ObjectModel.ObservableCollection<SilverlightWebService.Order> orderlist1 = new System.Collections.ObjectModel.ObservableCollection<ConcourseSilverlight.SilverlightWebService.Order>(); foreach (SilverlightWebService.Order aorder in Orderlist) { if (aorder.CheckedItem == false) orderlist1.Add(aorder); }  dgOrders.ItemsSource = orderlist1; -------------- DataGrid will be repopulated. But values selected will be defaut ones, that means data selected is not retained. may be itemsource is changes. how can I resolve this        

Hi,

Many of you might have noticed that the WPF DataGrid looks very blah compared to the Silverlight DataGrid.

Here are the WPF DataGrid Screenshot and Silverlight DataGrid Screenshot.

See how in the Silverlight DataGrid the lines are better, there are alternating row backgrounds and the selected row also looks better.

I am surprised the WPF DataGrid doesn't use the same styles by default as the Silverlight.

Has anyone styles the WPF DataGrid to make it look like the Silverlight DataGrid and if so can you share the templates with me?

Or is there a built-in theme in WPF DataGrid that looks close to the Silverlight DataGrid?

Thanks

Hi there,

 

I am parsing a table in my Silverlight application. Lets say the table is as follows

*   A   B   C

A   1   2   3

B   3   4   6

C   2   2  2

I do not know before hand the column names, how many columns there are so, as far as I know, I can only see a solution to presenting this as a table with the traditional unbound data strategy as in windows forms.  However, my solution is in Silverlight, so I necessarely need to bind to an object.  But as said, I do not know the object properties, so I got stuck.  Please help; this seems like it should be very simple to display a parsed table.

 

Many thanks. 

 

In this post I will show you how to select single check-box control when you have single check-box control in each row of the datagrid control. As you all know that check-box controls are normally used for the multiple selection and radio buttons are used for single selection. But there are sometimes requirement that control should be check-box and selection should be single. Mean if user view data in the datagrid control then he/she should only select one check-box at a time not more then one. Main page is shown in the Image 1. Here you can see that I have placed check-box control in the first column of the datagrid control which I have also highlighted.

In this post what I want to learn and to share something like how to get the selected items from the data grid control of the Silver light using MVVM. You can see the main output of the example code in the Image 1, here you can see that I have a data grid control and three button with label Add, edit and delete records. Let me explain you what is happening in the example code, user is allowed to select multiple record from the grid and the selected records Ids are displayed in the "Selected Ids" area. If user select only one record then add and edit buttons are enabled and if records are more then one then add and edit buttons are disabled. Similarly If number of selected item count is shown in the delete button text.

Even if mobile dev is not my every day work, thanks to the .Net Compact Framework, it's still .Net programming.

Here is the scenario:

You come back home, you have a windows mobile phone wifi capable and you want to quickly get access to your phone pictures from your home network.
You just activate the Wifi, run my app and then browse to the provided link from any computer on the network.

The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

Before we talk about jquery inside any itemtemplate (repeater, gridview, datagrid), we need to understand the basic use of jquery functions

Listboxes are very tricky to set selected items in grid - there is no real nice way to do it. It would have been great if Microsoft included a property that accepts an array or comma separated values - or anything! But they only allow each item in the list to be selected individually. The way to do this in a grid is a bit messy, but it is fairly simple to implement. When a row is created (as per the event), select the items of the listbox as per the datagrid source data:
