Change An Asp Datapager's Pager.PagedControlID Property At Runtime?
Sep 20, 2010
This property was originally set in the aspx file, however I want to change it to select programatically on page load. I set the Pager.PagedControlID property, but I receive the following error message on this line:
Pager.PageSize = Convert.ToInt32(ListLength);
Page properties cannot be set because no IPageableItemContainer has been found. The ID I am using I copied and pasted out of the inline aspx and I checked it is correct.
I'm using datapager in my listview control and I want my datapager to always set to default as numeric pager field equals to 1 every time. I change the items of the dropdownlist as its pagesize where dropdownlist is set to autopostback. For example if the currentpage is on page 3 but when I select any item from the dropdownlist I want to set the datapager back to its default as numeric pager field goes back to 1. How do I do this?
In my repeater m using linkbutton for paging. I want javascript or code... My question is at run time when I am clicking on linkbutton its color get change... When I click on another button its color get reset...
I've created links in the listview which is attached to the datapager. When a user clicks a link they see content to the left but the datapager changes from any page to page 1.
I am trying to make Datapager with listview inside updatePanel but i need that datapager maintains the page Index even the page has been refreshed, i tried QueryStringField but now it causing postback
how to do and why QueryStringField causing Postback even the controls are inside UpdatePanel.
Is possible change text in this button, and how? Default is "First", but i need change language.
Second is, inside DataPager I have <asp:NumericPagerField ButtonCount="4" /> but it isnt work without Javascript. Can I make it work without Javascript.
title says all. I guess we all get into situation like this one on daily basis. Pager as UI is useless if there is less than PageSize items in DataObject binded to ListView or other types of Dababindable objects.
I'm using a DataPager for a ListView, it works well, I'm using ButtonType:Image to style it but I want to change the image while mouse over, but I can't, I've tried some with ButtonCssClass but there's no good result. Here is my DataPager:
[Code]....
So, is it possible to change the image while mouse over?
I have a scenario where and array consists of values of different types.
During runtime I need to cast the current index to its type to get its property value
for eg: I have an array events[100];
the current index events[i] could be of any type say TYPE1.The TYPE1 could have multiple properties.During runtime, while iterating, I need to get all the properties and values of TYPE1 by casting the events[i] to the specific type, which I form as xml string and pass to DB.I'm at loss what way of reflection would achieve this.
P.S: I dont know the property of current index at runtime, which is why I'm collecting all the properties and dumping in DB.
I'm building a custom web control with a public property which I only want to be available in design time (i.e. make it unavailable in code behind). The DesignOnly attribute promises to do just that, but when I set [DesignOnly(true)] it has no noticeable effect whatsoever:
[Bindable(true)] [Category("Appearance")] [DefaultValue(null)] [Localizable(false)] [DesignOnly(true)] public string MyProp { get { return ViewState["MyProp"] as string; } set { ViewState["MyProp"] = value; } }
The property still appears in code behind IntelliSense. Setting a value to it in code behind works. In these respects, the behavior is just as if the attribute had never been set. And I've cleaned and rebuilt the complete solution. Twice.
I have an example about Products Catalog using LinQ and ListView, DataPager, It works fine but I don't why but something's wrong with my DataPager while I click to change page, I must click 2 times on data pager link to change page.Here is my code:
I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.
When page loads,I get error - Specified cast is invalid!
Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.
Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.
I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.
I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.
Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.
how i can edit and update Checkbox.
where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.
I am trying to use jGrowl in ASP.NET, but am getting a Microsoft JScript runtime error: Object doesn't support this property or method error when trying to run the page in IE.
I am trying to validate my gridview checked checkboxs, using code below.
I get "Microsoft JScript runtime error: Object doesn't support this property or method" error when button is clicked and i used breakpoints to check strangely, i am getting back gridViewx count=3 in javascript function. my gridview has nested gridview?
CodeBehind.aspx page on_load ActiveAssignButton.Attributes.Add("OnClick", "return IsCheckBoxSelected(" & GridView2.ClientID & ")") html page function IsCheckBoxSelected(gridViewx) { if (gridViewx != null) { var chkBoxes = gridViewx[0].getElementsByTagName("input"); for (i = 0; i < chkBoxes.length; i++) { if (chkBoxes[i].type == "checkbox" || chkBoxes[i].type == "CHECKBOX") { if (chkBoxes[i].checked == true) { return true; } } } alert("At least one ticket needs to be selected!"); return false; } }
I am writing a Web Application in ASP.NET using C#. Whenever I run it, I get three types of Runtime Javascript Errors.
My Problem is that even though I am running a new Web Application with out any modification, then I also get the same errors.
These are the errors:
Microsoft JScript runtime error: Object doesn't support this property or method at document.addEventListener("mousemove", updateLastMouseMoveCoordinates, false); Microsoft JScript runtime error: Object expected at divSurveyInit(); Microsoft JScript runtime error: Object doesn't support this property or method at enter code here: document.addEventListener("mousemove", updateLastMouseMoveCoordinates, false);
I have a datapager connected to ListView1, and after 10 records have been added to the ListView any further input of records gets added to the next page, but this now current page is not displayed, so how do I get it to change to the current changed page automatically ?
(with a gridview control you could just use this below:-)
In my website1, I posted some data to my website2 by doing an HttpWebRequest.The data are posted successfully but what I wanna do is change the imageUrl in website2 after website1 fired some data. When I try to debug, I can see that it passes through the code of changing the ImageUrl, but when I view the source of website2, I can't see the imageUrl being change at all... Does anyone have a clue?
i m using embed tag for displaying video file.i want to change file in src attribute of embed tag runtime when i click on button.how can i access embed tag in my .cs file .
At runtime I would like to be able to change the ascx to another path, it would still be inheriting from the same usercontrol codebehind, it would just be a different template.
I'm filling a previously created DataGridView on an ASP.NET Web Form dynamically with a DataTable, but I want to change the name of the columns that appear on that DataGridView, and I simply can't figure out what I'm doing wrong. Below is the code:
DataTable dtUsuarios = DBManager.RunSqlGetDataTable( @"select b.UserName, c.Email, c.IsLockedOut, c.LastLoginDate, case when e.RoleName is not null then 1 else 0 end Admin from dbo.aspnet_Applications a join dbo.aspnet_Users b on a.ApplicationId = b.ApplicationId join dbo.aspnet_Membership c on b.ApplicationId = c.ApplicationId and b.UserId = c.UserId left join dbo.aspnet_UsersInRoles d on d.UserId = b.UserId left join dbo.aspnet_Roles e on d.RoleId = e.RoleId where a.ApplicationName = 'Mont Blanc Catalogo'"); dtUsuarios.Columns["UserName"].Caption = "Nome Usuário"; dtUsuarios.Columns["Email"].Caption = "E-mail"; dtUsuarios.Columns["IsLockedOut"].Caption = "Bloqueado"; dtUsuarios.Columns["LastLoginDate"].Caption = "Último Login"; dtUsuarios.Columns["Admin"].Caption = "Administrador"; DataView dvUsuarios = new DataView(dtUsuarios) { Sort = "UserName" }; gdvUsuarios.DataSource = dvUsuarios; gdvUsuarios.DataBind(); //gdvUsuarios.Columns[0].HeaderText = "Nome Usuário"; //gdvUsuarios.Columns[1].HeaderText = "E-mail"; //gdvUsuarios.Columns[2].HeaderText = "Bloqueado"; //gdvUsuarios.Columns[3].HeaderText = "Último Login"; //gdvUsuarios.Columns[4].HeaderText = "Administrador";
Setting the values changing the caption of the DataTable doesn't work, and after the DataBind, the Columns.Count property for the DataGridView return zero columns! After executing the code, everything appears normally at my asp page, but the captions are wrong.
I have tabs in a page. Each tab has a background image of fixed length. So when the text for the tab is bigger("arrangement help"), it displays "arrangement" in one line and "help" underneath. My goal is to display arrangement and help in one line. Tabs have to customizable.I am using css for regular tabs.
#tabs a { float:left; background:url("../images/selection_deselect_bg.jpg") no-repeat right top; margin:0; text-decoration:none; width:105px; text-align:center; height:24px; font-size:12px; color:#00779c; font-weight:bold; text-decoration:none; }.
I have an bigger image and i am able to get the size of the text in tab. But how to use bigger image for the tab? How to use change background on runtime.
