gridview

问题 I want to build an app that displays images in a gridview by using the picasso library. The images are retrieved by a remote server. Should I make an AsyncTask class or is this class handled by Picasso Library itself? All the picasso tutorials I have seen so far seem a bit vague. Thanks, Theo. 回答1: Its very simple to use picasso lib for loading images in gridview, as demonstrated here, class SampleGridViewAdapter extends BaseAdapter { private final Context context; private final List<String>

问题 I'm trying to set up my very first WPF ListView/GridView and having trouble with styling the column headers. I currently have 3 issues.

I want to remove the MouseOver effect. This screenshot has the mouse over the 3rd column which turns the background to white. How can I override the horizontal

问题 I've got a WPF ListView/GridView spec'd in XAML. The first column uses a CellTemplate to specify icons and the others use DisplayMemberBinding to populate themselves. The icons column is 20 wide, the icons 16 but they're getting truncated by margins/padding/something. I can't work out where it's set. Here's the essentials (I've removed some columns because they're the same): <ListView.ItemContainerStyle> <Style TargetType="{x:Type ListViewItem}"> <Setter Property="IsSelected" Value="{Binding

问题 This might be quite a strange question since usually people bind only complex types to a gridview. But I need to bind a List of Int (the same is for strings). Usually, as the property to bind one uses the name of the property of the object, but when using a Int or a String, the value is exactly the object itself, not a property. What is the "name" to get the value of the object? I tried "Value", "" (empty), "this", "item" but no luck. I'm referring to a gridview in a web form. Update There's

问题 I have a GridView, using a custom adapter (myAdapter extends BaseAdapter), where each item in the grid holds an ImageButton. getView() is working fine. However, from elsewhere in my code, how can I update the image (setImageResource) for one particular item in the grid based on its position in the GridView? So far, I've added this to my adapter class: public void changeImage() { Log.d(TAG, "Image change"); this.ImageButton.setImageResource(R.drawable.newImage); } And would like to write

问题 Need some help to solve this.

问题 I have a GridView control in an Asp.net application, that has a <asp:buttonField> of type="image" and CommandName="Delete" . Is there any way to execute a piece of javascript before reaching the OnRowDelete event? I want just a simple confirm before deleting the row. Thanks! EDIT : Please Note that <asp:ButtonField> tag does not have an OnClientClick attribute. 回答1: I would use a TemplateField instead, and populate the ItemTemplate with a regular asp:Button or asp:ImageButton, depending one

问题 I would like to change the text of the autogenerated "select" column in an ASP.NET GridView control. The text needs to be changed to the value of a DataField . I suspect that there is a very logical way to do this but I am missing it. I am able to add controls and data via the pre-render event but is there an easier better way? 回答1: Use the TemplateField and place into it buttons or linkbuttons with appropriate CommandName property: ButtonField.CommandName Property You may set this button
