I'm having a problem with the results of a Gridview. The SQL statement I use works in SQL Management Studio, but in my .NET app, it only display a few of the results. The part of the SQL that seems to be effecting it is in the where statement I use like:

't By the way, I'm using an image control to display the binary data and I'm aware that that will only work to display images, I just don't how to access all the other types of files once uploaded.

When i bind data to this grid view, i get an error saying column "PM 2" was not found. For some reason, the program is dropping the .5 from the column name. I am exploring the possibility of replacing the number with alphabets only but this may not be possible as the end user may not find it user friendly. Is there a way for me to get around this problem? I get a similar problem with B(a)p, it drops everything after the B. Any ideas on how to get the gridview to bind column names with special chars in it?
i have a gridview in each row of gridview row i hve 2 columns. in each row i need a button to enter date, when i click button one calender shld popup and data shld be display at end of the row
I'm quite new to ASP.NET programming, so excuse me if my question is dumb.I have the need of showing a grid (A GridView ?) of boolean values. But instead of showing checkboxes, I want to show the cells filled with black (value is true) or white (value is false). I understand I can do that by crafting a TemplateField and changing the style of the cell to select the correct background color and never displaying an actual value. I have not tried but I think it could work. The grid will contains 99% of boolean values and will contain something like 20 rows of 100 columns (2000 cells).
Now I would like to have that grid edited in place at client side, that is with JavaScript, changing the style of the cell when the user clicks on the cell. There would be a submit button somewhere to postback the whole thing.Is that possible ? Any hint for programming it ?Since I have a lot of webforms which needs to display that kind of grid, I would like to go further and design a custom GridView (or other control) that I could install in the toolbox and reuse easily.
Not sure if what I am trying is right way or not but just explain what I am trying to achieve - On my form I am displaying some data in a gridview; one of them being a default date. I also have a button which when clicked displays a modal window (using modalpopupextender) with a text box and an OK and Cancel button. What I am after is is there any way I can display, within the modal window the default date value so that the user can see what this value is and enter an appropriate date value into the textbox in the modal window.
I have the following code: using System; using System.Collections; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using Oracle.DataAccess.Client; // ODP.NET Oracle managed provider using Oracle.DataAccess.Types;
namespace MyTestApp { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { OracleConnection conn = new OracleConnection("User Id=UID; Password=PWD; Data Source=XE; Pooling=false"); try { conn.Open(); } catch ( OracleException oe ){ Console.WriteLine("ERROR : " + oe.Message); } if ( !Page.IsPostBack ) { if (conn.State == ConnectionState.Open) { // get data GetMoleculesToShow(conn); } } // clean up connection conn.Dispose(); } static void GetMoleculesToShow( OracleConnection conn ){ String division; String rxotc; String molecule_name; String prodnum; String proddesc; String molecule_class; String nonactive; // create command object and set attributes OracleCommand cmd = new OracleCommand("schema.package.procedure", conn); cmd.CommandType = CommandType.StoredProcedure; //Bind values cmd.Parameters.Add("mol_to_show_cur", OracleDbType.RefCursor); cmd.Parameters[0].Direction = ParameterDirection.Output; try { // Execute command, have parameters populated cmd.ExecuteNonQuery(); // Create OracleDataAdapter, data provider object to populate dataset OracleDataAdapter da = new OracleDataAdapter(cmd); //Populate dataset with "molrefcur" DataSet ds = new DataSet(); da.Fill(ds, "mol_to_show_cur", (OracleRefCursor)(cmd.Parameters["mol_to_show_cur"].Value)); //Verify dataset is begin populated //DataTable dt = ds.Tables[0]; //foreach ( DataRow dr in ds.Tables[0].Rows ) //{ // division = dr["division"].ToString(); // rxotc = dr["rxotc"].ToString(); // molecule_name = dr["molecule_name"].ToString(); // prodnum = dr["prodnum"].ToString(); // proddesc = dr["proddesc"].ToString(); // molecule_class = dr["molecule_class"].ToString(); // nonactive = dr["nonactive"].ToString(); //} if (ds.Tables[0].Rows.Count != 0) { // display dataset values GridView gvMolecules = new GridView(); gvMolecules.DataSource = ds.Tables["mol_to_show_cur"].Rows; gvMolecules.DataBind(); } } catch (OracleException oe) { Console.WriteLine("ERROR : " + oe.Message); } finally { cmd.Dispose(); } } } }
The dataset is being populated, however when the page renders, the data nor the gridview are visible. I have tried using both IE and Firefox, binding / not binding the columns, AutoGenerateColumns Y / N with no success. As I am new to all of this ( VS2008, ASP.NET, C# ) I can't help but to think I am overlooking something basic.
I am using the following : - VS 2008 - MS Vista SP2 - Oracle XE ( local )
i have a table with a bindary data field in it (excel, pdf, word files etc).
In gridview i want to have a colum that the user can click on to open or download that file. The file is stored in the database and not on the directory.
I have searched some things but only came up with complex stuff.. I am trying to stay away from complex because i am a total noob.

I have a Gridview with a hyperlink field. The hyperlink will open a pdf file from a folder in the root of the web if there is a corresponding file. My problem is that there may or may not be a corresponding file and if there isn't a file then a browser window opens up and the contents of the folder are displayed. This folder will be maintenanced from day to day adding and removing files. coding something that will either disable the hyperlink were there is no corresponding data or just pop up a message that there is no corresponding data to view.

I need to display some data in a gridview. Its shipping data.
Part of the data can come from a generic database query. Static shipping data that can be looked up from the database. Part of the data is external and has to be queryed from USPS. Any suggestions on what is the best way to accomplish this.
Should I just programmatically fill the gridview from the code behind doing the database lookup manual and filling the gridview with manual data then going out and filling the rest of the gridview with the data obtained from the USPS service?
I have seen several Web Sites that use GridViews that have lookup fields with different Value and Text Fields (as in drop down lists) but I can't seem to figure it out how to display the Text Field in the Item Template when the Text Field is not in the datasource. .
Here's what I have. I have a Gridview whose datasource is a Linq to SQL Invoice table, e.g.
InvoiceID CustomerID InvoiceNumber
THe Customer table is related to the Invoice Table thru the CustomerID. The relationship is defined in SQL Server and is displayed in the DBML.
I have created a template field for the CustomerID field in the Gridview. I would like to display the CustomerName when the Item Template is displayed and a DropDownList in the Edit Template. The DropDownList works great, but I cannot seem to figure out how to display the CustomerName in then Item Template.
I seem to remember seeing in some video that you can simply drag the CustomerName into the CustomerID Item Template Field. But I can't seem to find the customerName field. The DataSource includes the Customer Table because of the relationship, but no fields are displayed.
I suspect this is real simple, but I cannot seem to find an article or video that explains how to do this.
I have a gridview and would like to display one of 5 icons depending on the value returned from the database for that row (simply just A, B, C, D or E). Which event in my datagrid should I be looking at to check what value I'm getting? I presume once I can check a value I can simply set an image source using if statements?
I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?
I have an object datasource which is using Business object as a myconnection
The method i have defined under myconnection is
Publicstatic DataTable getfn(String dtype, String did, String dprefix, String dname) { datable table = new datatable(); then declared stored proceedure and defined parameters and assighned values
In the stored proceedure it has a query like select column1,coloumn2,coloumn3 As Call from table where I need to take data from Call and display it to the gridview through object datasource .
