问题 I would like all rows where in particular field name 'hello' is present to get colored green. I tried this on customdrawcell : if abstable1.fieldbyname('somename').asstring = 'Hello' then cxgrid.canvas.brush.color:=clGreen But it wont work... what am I missing here ? 回答1: Don't try to change canvas colors in the Grid.

问题 I have a set of TextBox that will automatically compute the 'total' based on 'gross amount' ( user input ). Each text box has a condition that is based on another text box. My computation works perfectly, but I need a CheckBox to allow the user to decide whether to remove the 'tax' or retain it. Every time the CheckBox is checked, the value of the text boxes that I have became zero. Can anyone help me with this? Here is what I have so far. JavaScript $(document).ready(function () { Number

问题 I am trying to submit a JS function from the code behind of a "DisplayBrandGridView_RowInserting" event. When the RegisterStratupScipt runs, nothing happens and the JS function is not even hit. After a record is inserted into the DB (which is successful from within this event), I need to immediately execute the JS function which will show a button to add data to another table. Note that this JS function works fine when executed from the client side. I don't care whether it's executed from the

问题 I have a devexpress nested gridview. Both the master and detail gridviews have link buttons for edit and add new activities. After either inserting new row or updating an existing row, I have to show a message box saying "Your update has been saved successfully". This could be a simple javascript alert box or a message displayed on the page itself. Both the gridviews use objectdatasource. I tried the following codes in the RowUpdated event of both the gridview and the objectdatasource: System

问题 The DevExpress XAF does much basis work for you, it creates a database based on your business objects, and dynamically generates a UI based on these, with basic functions like add, delete, sort etc. already present. This leaves me wondering how to go about properly designing and modelling an application built on this framework.

I am sending my code. private void B_Click(object sender, EventArgs e) { Button bt = (Button)sender; int productId = (int)bt.Tag; AddProductDataContext db = new AddProductDataContext(); decimal Quantity; decimal.TryParse(txtCalculator.Text, out Quantity); gridControl1.DataSource = from inv in db.Inventories where inv.RecId == productId select new { inventoryName = inv.InventoryName, Quantity, Total =

问题 I need to check if there is any row checked in a Master-Detail AspxGridView. With the master I can use grid.GetSelectedRowCount()>0 But how can I check it with the detail rows using JS? Thanks in advance 回答1: to accomplish this you need to assign a unique ClientInstanceName to each detail grid and then access that particular detail grid on client side using the assigned ClientInstanceName, which in turn should include the master's grid row ID part, ie detailGrid_1 for the first row,
