Forms Data Controls :: Trying To Use A Couple Columns From SqlDataSource In Code Behind?
Jan 29, 2010
Basically, what I want to do is to get all my data in 1 statement and then pull data from that into a GridView. I already have the columns that I want displaying in the GridView, but now I want to insert a footer row in between the header row and all the datarows, that contains a couple columns that will be the same for every row in the GridView. So something along the lines of this:
I have a gridview that loads with a new datasource on button click event. On the gridview (which is located in a table columm incidentally) are 2 columns, a descriptor and a checkbox. The problem is that after postback, the column widths change, the checkbox column expands and the other column contracts. Is there a way to keep the gridview column sizes the same after postback?
I have been looking at this article: [URL] However, I have a question: Can't this be used with a sqldatasource, instead of binding the gridview behind? If so, how?
I have set a couple of my DetailsView fields to readonly=true. In Update mode the fields are readonly but in Insert mode they are not readonly. What do I do to set it to readonly or blank (no field for entry)?
I have tried several ways but just cannot figure our how to populate some formviews with the data I have brought up in a gridview.
Here is my code so far. I just showing the code behind because my gridview and forms are not a problem. Where I am stuck is at the GridView1_SelectedIndexChanged at the bottom of the code.
using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Web; using System.Web.UI;
I use MySQL database and SqlDataSource controls. I generate update and insert queries in my code behind.how I can get a list of columns from the SqlDataSource control?
I have been searching for some time on the net for guidance on this question. Finally thought I will ask here...
I have a gridview that needs to be generated from code behind. There is a column with a name field and the remaining columns give the different user-ids linked to that id. Like this:
-- NAME, ID1, ID2, ID3......
The Name column will be populated from a table that has the Name as well as number of ID's associated with that name. eg [Name1][3]
I need to display linkbuttons that link to user-id related documents in columns 2 to n for each name.How do I dynamically add linkbutton columns from code behind?
Can the select command of a SqlDataSource be given by code in the code behind file. Also by calling the SqlDataSource.Select can the select statement be executed?
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]
what i would like to do is when the value of my sqldatasource is returned, then if it is null, run a code, in my case, redirect them to the login page, heres my code:
string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString; string insertSql = "SELECT * FROM LoggedInUsers WHERE UserId = @UserId"; using (SqlConnection myConnection = new SqlConnection(connectionString))
[Code]....
Now what i would simply like to do is, if the select statement searches the database, and the result is not found, the simply redirect them to "register.aspx"
I'm binding a gridview from a webservice with 30 columns and 10 rows, I need to print the same in a PORTRAIT, for that i decided to display columns as rows and
I searched on this all morning, but I'm still not sure. If I create a session variable to pass some data between a couple of pages, does that variable time out after it reaches the timeout period set on IIS, or will it persist for the entire time the user keeps a session alive? For example, session variable is used shortly after login and then never again. Susy uses other pages for two hours and keeps session active. Did that first session variable die after 20 minutes, or is it still there 2 hours later?
I am developing web-app in .NET for 5 months (and enjoying it =)) and I am reading 3 books, all of them teachs at least 2 methods for acessing data: ADO.NET and SqlDataSource object.
I am used to work with ADO.NET method because I feel that even if it needs coding by hand, I can separate the SQL routines from the page and I can customize database routines better.
For now I am using DataReader mode because the application and the database is on the same server and there is only 1Gb RAM available so there is no advantage using DataSet on this moment.
Am I thinking this right? There are some things with SqlDataSource that I don't know how to do it well...
For example:
I have a routine that inserts a record on a table then gets the ID of this record using SCOPE_IDENTITY() function of SQL Server, than it uses this ID to insert another record on another table. Because I use a one-to-many relationship on multiple tables...
How can I work this situation using SqlDataSource object, is it even possible?
I have a table with articles. Every article has a column named category which value is either 1 or 2 On my landingpage the article headers are displayed as hyperlinks. All the articles with category 1 will be displayed in a repeater control on the left side of page and all the articles with category 2 will be displayed in another repeater control on right side of page. I know I can bind the repeaters to two different sqldatasource controls with different SELECT statements. But I wonder if I can do this by only using one sqldatasource control, and if this is better and proper way of doing it. If so, do I create a (datatable?) and do the sorting there?
i designed a gridview to update, delete the records using sqldatasource, (there is no code in my aspx.cs file) but i dont know how to add the new row the gridview. so that if the table is empty then i cant add / update / delete the data.
how to Add new record on gridview using SQLDatasource without any code behind code?
i am facing a minor problem but can't find out its syntaxi have listview, and inside the template i have 2 labels, in design time i bind 1 label to one column thatis 'type' and depending upon this type i want to bind other labels to different columnsif type is question than 2 label will have to show data of question columnif type is job than 2 label will have to show data of job, so on........how to accomplish this,in databinding event handler i can check the value of typebut i want to know the syntax of binding 2 label in run time, with different fields using EVAL
I am using Visual Web Developer (VWD)and I dragged in i.e created a Gridview. In the codebehind of the page, I will like to declare an sqldatasource and get data from a database using the sqldatasource and then bind the sqldatasource to the Gridview. PS: I know how to drag-in an sqldatasource and attach it to the gridview using VWD but this time, I want to do this declaratively in the codebehind.
