Is there a way to define a <Columns> outside of a GridView in my .aspx file such that I can use those <Columns> in multiple GridViews in the same page? I have two GridViews that will have the same DataSource type, just with different content, and I'd rather not repeat all my customized TemplateFields in each. This seems simple enough, it's just I'm new to ASP.NET. Coming from WPF, it feels like I should be able to define my <Columns> in some parent "Resources" area, define its TargetType, give it a key, and then reference that key wherever I want those <Columns> to appear.
How can I get several GridViews on a single page to share the same Column widths?
I have four GridViews with (essentially) the same columns in each. They have unique headers and represent data from different queries. I want to maximize readability by allowing the columns to be dynamically sized based on the data but I don't want each GridView to do it independently. Having same-named columns one above the other with different widths looks very sloppy. Instead want all four GridViews to choose the same size for column 1, the same size for column 2, etc.
In windows apps I believe there is a property for this called SharedSizeGroup which allows you to set columns from different controls to collaborate when deciding on the optimum size.
Can this be achieved at all in ASP.NET? Is it just too much to ask because the dynamic column widths are up to the browser?
I see on the bottom of blog pages a sharing buttons (Twitter and Facebook), where if clicked the link behind (which is normally the blog page url) the fshare button takes the clicker to the blog site facebook page respectively.
How does one do this in asp.net 2 , does one one use the <%# %> in the url part of these share buttons, are there any examples of how this is done?
I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns() { // The first column to begin to insert the columns in the GridView int columnIndex = 5; BoundField aoColumn = new BoundField(); aoColumn.HeaderText = "New Column 1"; gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback gvMyGrid.Columns.Add(aoColumn); // works fine columnIndex++; foreach (MyEntity my in _myEntityCollection) { BoundField myColumn = new BoundField(); myColumn.HeaderText = String.Format("{0:d}", my.StartDate); gvMyGrid.Columns.Insert(columnIndex, myColumn); columnIndex++; } }
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.
I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:
in asp.net page user able to select gridview Columns, and it will hide remaining columns and that selection done by check box with column list bellow is Image link , what exactly I am looking for [URL] it look bellow after selection of column done [URL]
I've created a new ASP.NET website. I've generated an Entity Data Model from my database and have dropped a entitydatasource and gridview onto my page and wired up the gridview to pull from the entitydatasource. Now I get columns like this: id extension prefix did_flag len ten_id restriction_class_id sfc_id name_display building_id floor room phone_id department_id
In each case where the item is named something_id this reflects a foreign key relationship in the database - and I did choose to have the EDM expose foreign key relationships. I'd like to make it so the gridview pulls in the values for these foreign keys rather than just showing the ID numbers - so, for example, department_id might have a value of "101" right now but it should pull from the department table "Marketing".
I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
I am developing an web application. One of this form has a textbox. When the user enter chars i need to fetch the records from db and display as 4 columns in AUTOCOMPLETEEXTENDER CONTROL TOOL KIT and it's column name also. When the user click any one of the row, i need to get the 2nd clicked column name and display it in textbox.
how to display 4 columns and it column name in autocompleteextender control?
I am trying to arrange the report parameters in three columns instead of two columns. I have about 13 report parameters . Is there a setting anywhere to be done.
I have a gridview with predefined columns and a selectcommand. Why do I get the columns twice? I want to keep the predefined columns and the selectcommand, but avoid getting the columns double.
i have dataset ds with 4 coloums. the 4rth colom has values either '1' or '2'. i want to split this ds into 2 datasets ds1 and ds2 depending upon whether 4rth colom is '1' or '2' .
then i want to bind gridview1 to ds2 and gridview2 to ds22.
I'm creating a table in an asp.net code behind dynamically, and I want to have a footer row that only has 2 cells. The first should span all the columns in the table-1. Is there some way other then keeping track of the # of columns in the table manually for me to set the colspan to be # of all the columns in the table-1? Preferably a HTML or CSS solution?
I've the following code which successfully makes an average for all the columns from a table. What I need to do though is ignore certain columns in this equation.
Dim totalNumber as Double = 0 Dim count as Integer = 0 For x = 0 To xyz123.Tables(0).Columns.Count - 1 Dim current as Double = 0 If Double.TryParse(xyz123.Tables(0).Rows(0)(x).ToString(), current) AndAlso current <> 0 Then count += 1 totalNumber += current End If Next Dim averageRating as Double = totalNumber / count
I apologize for the odd title. I've been trying to figure out how to do this and can't quite put it into words. Basically, I need to try to display a GridView with a whole bunch of columns (37 in one case) in two "rows" of columns. More or less.
So instead of this:
Column1 Column2 Column3 Column4 Column5 Column6 Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data
I'd like something like this:
Column1 Column2 Column3 Data Data Data Data Data Data Data Data Data
Column4 Column5 Column6 Data Data Data Data Data Data Data Data Data
As in the example there can be multiple rows returned which all need to be displayed. I'm trying to stop a very large horizontal scroll bar being required. I've been searching as much as I can but haven't found anything that fits what I'm looking for.
I have 2 asp.net mvc2 projects in a solution. One is normal site for visitors use and the other one is admin back-end which is going to be separated by sub-domains like [URL] and [URL] The scenario is like admin will add a new item(e.g product) with image and [URL] will use that image to display product. Both application are sharing one db. so there is no problem to get the item details that is coming from the db. but for item image that has been uploaded in admin directory([URL]- any idea how to get it from general domain [URL]to display? Also what is the best way of separating the resources like image files or even css or js files across sites and how to access them?
I have 2 projects, where they both can upload attachments into a directory.
The problem is how do you get the projects to be able to access each others attachments or even save these attachments in the same folder...
At the moment my ProjectA saves uploads into its "uploads" folder... But when you are running ProjectB it doesnt have the same uploads folder (if that makes sense)
I have a web application (MainApplication) where many of the pages contain a custom Web Control that looks for some content in a cache. If it can't find any data within the cache, then it goes out to a database for the content. After retrieving the content, the Control displays the content on the page.
There is a web application (CMS) in a subdirectory within the aforementioned web application. Users use this CMS to update the content pulled in by the MainApplication.
When a user updates some content using the CMS, I need the CMS to clear the relevant portion of the cache used by the MainApplication. The problem is that, as two different web applications, they can't simply interact with the same static cache object.
The ideal solution would be to somehow share an instance of a cache object between both web applications.
Failing that, what would be the best (performance-wise) way of communicating between the two web applications? Obviously, writing/reading to a database would defeat the purpose. I was thinking about a flat file?
I begin with MVC and this technology is very efficient !
I would like to create several applications mapped with a common applicaton Users Accounts. The aim is to isolate logical parts. The problem is always the same : how to communicate easily between users db and appli db ? Do I continue to use my poor View mechanism from SQL Server (db1.Users.UserId inner join db2.Users.UserId) or is it a better way with super MVC?
