Documentation for using a checkbox with a gridview has the following statement:Because a check box can display only a selected or an unselected state, a CheckBoxField object can be bound only to a field with a Boolean data type or a string that can be parsed byParse.No example has yet been found to explain how using Parse to control the value of theis done. Interestingly enough I can find a fine example for the unlikely scenario of embedding a bulleted list in a grid cell.
I could use the DataContractJsonSerializer Class and have custom Classes defined. However, am not sure how keys like "$" would get converted to in .Net.
After much head scratching as to why my returned Json string is breaking JSON.parse, I have realized that it is the returned dates that it doesn't like.

I'm using the following code to upload images, pdf files, word files and excel to a sql table as binary data. However, I can only figure out how to display the images but am clueless about the other type of files. What adjustments do I need to make so that with a button click I can access the other files? '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.
I'm trying to display data from this table in a gridview using template fields. Here's an example of a label in my item template
[Code]....
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'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:

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.
in my asp.net+access web code in vb. There is three labels named (tata.text,tvs.text,msu.text) is there any option on clicking on the label named tata.text the data pertaining to tata be displayed in a gridview in another page or a popup display in same page.
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 )
