I have to freeze the first column in a data grid. i have done freezing part but the issue is vertical and horizontal scroll bar movement getting slow. in my data grid each row contains 18 textboxes and 18 image buttons.if number of rows count around 15 then the scroll bars working almost properly.issue in morethan 15 rows
For freeze i am using CSS.Platform is asp.net1.1
in CSS i am using below given codes. div#div-datagrid { width: 200px; height: 200px; overflow: auto; } /* Locks the left column */ td.locked, th.locked { position:relative; cursor: default; left: expression(document.getElementById("div-datagrid").scrollLeft-1); } /* Locks table header */ th { font-size: 14px; font-weight: bold; text-align: center; background-color:Navy; color: white; border-right: 1px solid silver; position:relative; cursor: default; top: expression(document.getElementById("div-datagrid").scrollTop-4); z-index: 10; } /* Keeps the header as the top most item. Important for top left item*/ th.locked {z-index: 99;}
I'm building an n-tier application, with the web client and the class library separate. I'm also using the factory pattern of development, using interfaces to act as containers for different objects they are associated with. The problem I'm expreriencing is that I declared a public interface class in the class library and I can create an instance of it in in my aspx pages but whenever I declare it in my custom control code-side, i get an error, like so:
Error 20 The type or namespace name 'IContentMaker' could not be found (are you missing a using directive or an assembly reference?)
notge that I have inherited the class library namespace using the 'using' keyword just in case you are wondering. My code is like so:
using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using TQO_Classes ; //importing the class library project public partial class PageContentMgr : System.Web.UI.UserControl { private IContentMaker _data; //this line throws the error, it works fine on aspx pages
I've build a custom server control inheriting from WebControl. Basically it is a kind of button. All is working perfectly except one thing: the PostBackUrl is inoperative.
I probably forgot to implement something. Actually I just added the property PostBackUrl. Probably I should also implement an interface of call something.
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.
I have Datagrid , i want to clcik on row and get data in textbox , but my textbox is FreeTextBox control,i tried to use javascript but work for asp.net control not working for freetext box control, how i can capture this code is sample code but it work for asp.net control but not working for my freetextbox

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
I have 2 datagrid (using .net 1.1). I need to access column of second grid ( i need to make a column of second grid as disabled) when i click "Cancel" link button in First Grid. How can this be done?
I am looking at implementing a custom MappingSource as side project. It needs to be something along the lines of AttributeMappingSource and XmlMappingSource, except that it won't be using attributes or xml. This has been a problem so far. All the documentation I've seen uses these two, and only these two. I know how to define the new classes and implement the abstract methods, but there are a few problem. Let's take a look at the mapping source first:
public class CustomMappingSource : MappingSource { protected override MetaModel CreateModel(Type dataContextType) { // it is suggested to create a new metamodel and pass in // the current metamodel held in the datacontext. return new CustomMetaModel(GetModel(dataContextType)); } }
Ok so far, except that it's a new generic context, and no model exists yet. For example, I want to be able to do this:
DataContext = new DataContext(connectionString, new CustomMappingSource());
Now let's look at one of the CustomMetaModel's overriden methods:
public override MetaTable GetTable(Type rowType) { // there are no methods or collection exposed in 'this' to // add, remove or alter the table mappings. }
How do I do this? as you might be guessing at this point, I am looking into building a FluentMappingSource. NO! Don't point me to FluentLinqToSql. I have it and their mapping source isn't even derived from MappingSource.
I have "Order" object with Columns Ticket,OTP and CustomerName etc.Intially on DataGrid, I'm binding Ticket only , when user clicks on "Column Chooser" button, another windows appears to pickup CustomerName,OTP columns to add specified column dynamically on Datagrid. Environment : Asp.net ,C# with Object Data source
Public Class Order { publc void Order() { } public string Ticket { get { return this.strTicket; } set { this.strTicket = value; } } public string OtpNumber { get { return this.strOtpNumber; } set { this.strOtpNumber = value; } } public string CustomerName { get { return this.strCustomer; } set { this.strCustomer = value; } } } }
I've been working on implementing a custom section in the web.config file for a little something I'm working for the past few hours, but I can't seem to get it working. The following is what I'd like to use as my XML structure:
JS:function customButton_OnClick(s, e) { if (e.buttonID == "customButtonId") { e.processOnServer = confirm("Really want to delete?");[code]....
now on the server side I user linq to delete specified row and then submit changes to my DataContext and then DataBind() on my grid.
Problem is that sometimes standard ASPxGridView loading panel is shown for about 1 second ant then my row dissapears so it behaves properly but sometimes loading panel stops mooving. and I need to move mouse over my grid or click button so that my Grid is updated(row dissapears).
The problem is when i go to a URL that does not exist is still uses the 404 error page specified in IIS Manager.Question: How can I make it use the error.aspx page I have created? Why do the settings in IIS Manager override the web.config?
I have a gridview that I want to implemenet a custom pager template using the data pager. How would I go about implementing the IPageableItemContainer, where would I put the code, in a sperate class, in the page class that I am implementing the gridview in and how to implement the code on a gridview.
In my asp.net application, users are created by the administrators & those users need to log-in into the system using their own email/password or openid. So what is the best option to implement in this scenario?
I mean, as users can't register them self,do administrator required to associate each openid with the users & what kind of table structure do I need?
And do I also need the log-in interface like that of [URL] showing multiple types of authentication(default & openid from various providers)?
I need to implement simple quiz in asp.net that displays question, its options and user can answer these questions by checking options and submit the result.
I think ListView is the best control to implement in a way that each Item is question and I need to display Option of the question using check box list.
In ItemTemplate, how can I specify such condition that give me the list of options to select for the user for the particular question in the same row. Just like this:
1. Question Text goes here: (Options to select for the user)checkbox1 goes here; checkbox2 goes here
2. Question Text goes here: (Options to select for the user)checkbox1 goes here; checkbox2 goes here and so on
