问题 I have a DataGrid which is being bound dynamically to a database query. The user enters some search text into a text field, clicks search, and the code behind creates the appropriate database query using LINQ (searches a table based on the string and returns a limited set of the columns). It then sets the GridView datasource to be the query and calls DataBind(). protected void btnSearch_Click(object sender, EventArgs e) { var query = from record in DB.Table where record.Name.Contains

问题 I am in the situation of working with large amount of records in a grid. Instead of, binding all records into the grid. why we should not bind set of records which are belongs to 5th page. 回答1: You can enable paging on your GridView by setting AllowPaging to true and PageSize to the number of records you wish to display per page. The advantage of paging is that you can bind the full data source to your GridView and allow the user to move between pages, it's much less programming on the server

问题 I've searched around and haven't found a solution yet. I have a Gridview populated by a Stored Procedure that is called by a DropdownList. The query works fine and gives me a table with values. You'll see that I programmed text in the first column to be converted to Hyperlinks. Everything works fine with the exception that the first row (that's not the Header row) doesn't have a link. In fact, the hyperlink address is applied to the next row instead. And so it bumps the rest of the links down
