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).
I am currently using DevExpress ASPxGridView and want the selection check box to show a redcross image on selection or empty when unselected. Is there any javascript library to do such a thing. If so can you provide me an example.
try to have custom controls in a DevExpress grids detail row. When ever a row is expanded I would like to load data into those custom controls based on the Masters Key.I am using the detailrow expended method.
protected void grid_DetailRowExpandedChanged(object sender, ASPxGridViewDetailRowEventArgs e) if (e.Expanded) { int id = Convert.ToInt32(grd.GetRowValues(e.VisibleIndex, "ID")); ... }
The problem is I don't know how to access the custom controls in the expended detail row. I don't see any Row or Items properties on the grid, which would have been with a FindControl().
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 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'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:
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?
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 am trying to display checkboxes in front of every row in list view. So that after selecting the desired checkboxes user clicks on delete button and we should delete that records.
I have some simple shopping cart using DataTable and Session, all data are in datalist after user click "Add" the record go to gridview. how can i add delete button to delete row from the gridview?
I have custom gridview that inherit from the regular gridview.
On of the features is that is has a built in page size dropdown in an extra header row.
Another feature is that this extra header row has a place holder where aditional controls can be added but here is where I have some problems.
When I add a control that is created outside the gridview to the gridviews builtin placeholder and tries to do anything that performs a postback the gridview dissepears, but appears again on a new post back.
Here is the code for the gridview:
[Code]....
And this is the way it is used in a usercontrol on page, the gridview is called gvList and the control that I try to add to its placeholder is the phrExtraHeaderControls:
[Code]....
What can be wrong, is the viewstate messed up in the postback so that the gridview can't be rendered?
How can I customize automatically generated command button, e.g. Delete?
I want to add a client confirmation on deleting and in the same moment I want this button would be generated on setting AutoGenerateDeleteButton="true". Is it possible??
In IIS 7.0 integrated mode after deleting all headers with Response.ClearHeaders() IIS would add some other headers like Server and X-Powered-By which reveals good information to hackers. How can I stop this behavior (consider I still need to add my custom headers) ?
However, the error message is never displayed and the processing continues. What's strange is that the custom validation method is called, finds the field, and properly sets up e.IsValid to false. It does not matter whether I check Page.IsValid or not, because the error message is not displayed anyway. It works if I remove the CommandName="Delete" from the button.
With Google I found the following solution, which seems to indicate someone has had a similar issue:
[URL]
But I want to make sure that this solution is the way to go. I mean, is custom validation really not supposed to work with a delete button in a databound control, seriously?
I'm attempting to create a custom control that extends the Table class. Inside of the table will be rendered a number of different controls based on a specified identifying property. On some of these controls, however, I need to specify validation for data types and requirement.To me, the most logical way of doing so is to add validators to the table and set their appropriate properties to specify which controls to validate. In doing so, however, I've discovered that none of the validators added will even render on the page in which the control is added. So is this a valid construct?Here's an example of what I mean:
I have created a custom control which uploaded files to the server . These uploaded files list that is the name of the file and the file path i save in a session and the files i save to a temp directory .
Now, I want to delete these files as well as clear the session when this control is no longer used .How do i find whether the control is no longer used in the page . I should be doing this from the Custom control and not from the Page ?
I have been trying find a way, where whan a basic user wants to reset a record due to a typo. The use has to get a admin to enter there user password to confirm the update. this is based on a sql server 2008 DB that will execute a stored procedure to perfom the reset update. I am coding in c# working on a 3.5 framwork. I have seen thare a many confirm popup message box options but none for a password to confirm.
My code is not updating the sql database. I am definately passing the correct information in to this function, and it runs without errors. If I exec the procedure with the passed in data, it works great. Can someone tell me what is missing?
