gridview

问题 I have a GridView which is databound, on button_click I want to read the GridView row by row each column and read the value of each cell in a row and update a table in database? I also know how to check if that cell contains null. I am trying something like this and got stuck: protected void SAVE_GRID_Click(object sender, EventArgs e) { int rowscount = GridView2.Rows.Count; int columnscount = GridView2.Columns.Count; for (int i = 0; i < rowscount; i++) { for (int j = 1; j < columnscount; j++)

问题 I have a GridView implemented and activated the mGridView.setChoiceMode(GridView.CHOICE_MODE_MULTIPLE_MODAL); mode. Now I have the possibility to select multiple items from my grid when I perform a long click on one item. I want to achieve this behavior on a normal, short click. Is this possible? 回答1: First, I'd suggest to think if this user scenario is what you have been looking for. By default, in Android UX to select something you do long press and it's a pattern users used to. So, maybe

问题 I've searched in google there's an easy way to delete a record with confirmation using this code: <asp:templatefield HeaderText="Delete"> <ItemTemplate> <asp:Button ID="deleteButton" runat="server" CommandName="Delete" Text="Delete" OnClientClick="return confirm('Are you sure you want to delete this user?');" /> </ItemTemplate> </asp:templatefield> But when i run it and click delete and clicking "yes" to confirm. this error appears: The GridView 'PendingRecordsGridview' fired event

问题 I have a GridView that has a DataSourceID pointing to an ObjectDataSource. The ObjectDataSource points to a method that returns a LINQ IQueryable by using the TypeName, SelectMethod, and SelectCountMethod properties of the ObjectDataSource control. What happens is that the data loads properly upfront. However, on postback, if I remove the rows from the GridView and try to rebind using the explicit GridView.DataBind(), it doesn't work. I know LINQ is returning the proper rowcount and such

问题 I am trying to get the selected row of the GridView , and I know that I should be able to get that information based on the OnSelectedIndexChanged event. Whenever I click on the row, the event does not fire. <asp:GridView ID="GridView1" runat="server" GridLines="None" Width="930px" CellPadding="4" ForeColor="#333333" onselectedindexchanged="GridView1_SelectedIndexChanged2"> <AlternatingRowStyle BackColor="White" /> <EditRowStyle BackColor="#2461BF" /> <FooterStyle BackColor="#507CD1" Font

问题 I am trying to do efficient paging with a gridview without using a datasource control. By efficient, I mean I only retrieve the records that I intend to show. I am trying to use the PagerTemplate to build my pager functionality. In short, the problem is that if I bind only the records that I intend to show on the current page, the gridview doesn't render its pager template, so I don't get the paging controls. It's almost as if I MUST bind more records than I intend to show on a given page,

问题 I'm using Picasso with a GridView, loading 200 images over the network. Right now it looks like Picasso is not triggering an image load over the network until the image starts to come into view on the screen. Is there a way to have Picasso pre-fetch the next N images in the list so that the experience is better? I am using an Adapter to put the images into the Gridview. 回答1: I am prefetching images into a cache very successfully using Picasso like so: if (BuildConfig.DEBUG) { Picasso.with
