问题 So I have been following this guide for data binding on Windows Forms controls (MAD props to the author, this guide is great), and I have used this to create a custom class and bind a DataGridView to a collection of this class: class CompleteJobListEntry { private string _jobName; private Image _jobStatus; private DateTime _jobAddedDate; private string _jobAddedScanner; private string _jobAddedUser; private string _jobLastActivity; private DateTime _jobActivityDate; private string

问题 I have looked through your questions as well as elsewhere on the internet for the past two hours and cannot find a solution for my problem anywhere, or at least I didn't understand it if I did. I apologize in advance if this appears redundant or inane. Let me be clear: the issue is that I am somehow NOT implementing the approach correctly, but I understand (or think I do) how it is supposed to be done. I have a gridview on a form in which I want to display custom objects representing

问题 The error I got when I change the datasource of BindingSource "databinding cannot find a row that is suitable for all bindings row that is suitable for all bindings" this.RemoveAllBindings(); // My work-around for the meantime bdsOrder.DataSource = _ds.Tables["orders"]; // errors here on second time around(first time is blank datatable, second time is when i open existing record, then it errors), dataset comes from Remoting bdsOrderDetail.DataSource = _ds.Tables["order_detail"]; bdsPhoto

问题 We are binding a DataGridview using BindingSource . So in the main thread we have given like this. class1BindingSource = new BindingSource(); class1BindingSource.DataSource = class1List; this.dataGridView1.DataSource = class1BindingSource; After that i have a placed a background worker in the form and is triggering in a button click. i.e. in the button click this.backgroundWorker1.RunWorkerAsync() In the BackgroundWorker DoWork Event i am trying to update the BindingSource and there by trying

问题 How can I update a column value in a binding source with code? I am trying for something similar to this: CustomersBindingSource.AddNew(); CustomersBindingSource.Current["CustomerID"] = Guid.NewGuid(); This code currently errors stating: "Cannot apply indexing with [] to an expression of type 'object'". Any help re-writing this is greatly appreciated! 回答1: BindingSource's Current property is very generic in what it returns: type object. Object doesn't define an indexer so your [] doesn't work

问题 I am using Vb.Net to load data from sql server database. I have the car datatable as follows: I load car details and distinct model values as follows: sql = " select * from car" daCar = New SqlDataAdapter(sql, sqlConn) daCar.Fill(dsDataset, "car") sql = " select distinct model from car" daCar = New SqlDataAdapter(sql, sqlConn) daCar.Fill(dsDataset, "model") Now when I load the form I have two bindingsources and have one combobox to display the distinct values of the model so user car modify
