阅读更多关于 How to filter dojo categorized treeGrid?

问题 I have dojo treeGrid that works fine. It shows projects with cost categorized by year. Also it shows totals. But when I try to filter it by one of column it mess up the grid (breaks categories and filter records improperly). Do I use grid.filter properly? I need to keep categorized structure but remove/filter certain records. Or should I refresh jsonStore somehow instead? //HTML <div id="treeGrid"></div> <a href="javascript:void(0)"> <span id='button1'>Filter</span> </a> //JavaScript var

dojox.grid.DataGrid: how to access data from a click event?

阅读更多关于 dojox.grid.DataGrid: how to access data from a click event?

问题 I'm using Dojo 1.5 (including dojox). I have a dojox.grid.DataGrid where each row represents a user. When I click a row, I want to redirect to a URL like /users/USER_ID. The user ID is one of the fields in the grid, so all I need to do in my onRowClick callback is to grab the user ID for the row that was clicked. The click event contains a rowIndex property, and, indeed, I found a (rather old) post elsewhere that suggested I should be able to do: var row = dijit.byId('grid').model.getRow(e

阅读更多关于 Set datagrid to show just 5 rows per page

问题 I am using DOJO for data grid presentation <div id="grid_log" dojoType="dojox.grid.DataGrid" store="log" structure="window.layout_log" queryOptions="{deep:true}" query="{}" clientSort="true" rowsPerPage="5"> </div> but problem is that grid_log doesn't show just 5 rows per page. What is wrong with this tag ? Why ignores rowsPerPage="5" ? 回答1: It's look like the rowsPerPage value isn't pages that are "viewed" - but rather, "virtual" pages. That is, the grid only renders portions of itself at a

How do you conditionally style a cell in a Dojo data grid?

阅读更多关于 How do you conditionally style a cell in a Dojo data grid?

问题 Essentially what I want to do is to apply additional CSS classes to individual cells in a data grid based on the value of the cell. An example would be to color the text red when a dollar value is negative. The only solution I've found was to use the formatter of the column to create a string for a span that has the class based on the value passed in. I figure there has to be a better way. 回答1: When specifying the structure, you pass in an object that represents the widget configuration for a

问题 I am adding a new blank row to a dojox.grid.DataGrid, and want to focus in the first cell of the new row. I add the row by calling: var new_row = {}, attributes = store.getAttributes( items[0] ); dojo.forEach( attributes, function( attribute ) { dojo.forEach( attributes, function( attribute ) { new_row[ attribute ] = null; } ); } ); store.newItem( new_row ); I believe the following code will do the focusing: grid.focus.setFocusIndex( row_index, 0 ); grid.edit.setEditCell( grid.focus.cell, row
