I am trying to create a recipe system that will pull material amounts from an already built inventory database upon request for testing purposes of the different recipe runs. What is throwing me for a loop is that each time a user will request a recipe comparison they will have a different number of recipe trial runs for comparison purposes. In order to do this I'm guessing you will need to generate a gridview-like control with a dynamic number of columns which would be specified on a web form page prior to arriving at the recipe formulation page which will contain the control for the recipe formulation. As a result the user will have different columns and rows on this formulation page, with the rows being a static number of 30 (30 being maximum amount of ingredients to include in each recipe). The columns will contain the recipes to be compared, i.e. ProductRun1, ProductRun2, ProductRun3, where the number of ProductRunX will be determined by user input. So the user when they come to this aspx page will be presented with a blank editable grid of X columns by 30 rows deep. The left-most column will contain the ingredient names in a drop down box for users to select to input into their recipe and the rest of the columns will be editable fields where the user can type in the amount of each material to be used. The setup will look roughly like this:
| ProductRun1 | ProductRun2 | ProductRun3 |
ProductRun4 | ... |
-------------------------------------------------------------------------------------------------------
Material1 | Material1_Amt | Material1_Amt | Material1_Amt | Material1_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material2 | Material2_Amt | Material2_Amt | Material2_Amt | Material2_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material3 | Material3_Amt | Material3_Amt | Material3_Amt | Material3_Amt | ...|
-------------------------------------------------------------------------------------------------------
(...)
-------------------------------------------------------------------------------------------------------
Material30 | Material30_Amt | Material30_Amt | Material30_Amt | Material30_Amt | ...|
-------------------------------------------------------------------------------------------------------
So my question is how would I go about tackling something like this and what controls would I use. All of the forum posts around the internet show the GridView control being tied to data in a database already and not having the ability to have a fully blank and editable table upon the page loading so that it can accept user input. Another wrench into the situation is that the column numbers can vary. What control would be used in this situation or would it be better to use just a repeater of textboxes to build this type of control? Another thing is once the control is built how can you pull the data from such a control with the intentions of entering it inside a sql server database?
I have a gridview that has the following colums Category, Weight , and an option to delete row. I user would like to be able to highlight two columns in excel Category, Weight and then past them from clipboard to gridview.
View 1 RepliesI have started creating a DAL and have successfully bound my adaptor and the query within the adaptor to a gridview.
In lots of the intranet type apps I code in regular ASP for myself I often have a few columns with little icons in that do various things for that rows identity, such as drill down to more details, overlay a graph, text the person via an ajax call, send em an email via ajax and so on.
I think Ive got the hang of styling elements of each row depending on the data but Im completely at a loss as how to add a column which would have an icon whos url link properties would be dependant on the data.
EG
ROW1 | Name | Email Address | ICONFOR EMAIL(with a querystring id matching the row id) | ICON FOR MORE DETAILS (with a querystring id matching the row id)
I realise I am probably looking at this the wrong way but its difficult when you are almost on autopilot doing these things in classic ASP.
is there a way I can add a column dynamically from code behind to the gridview in my page?
View 5 RepliesI'm just wondering if anyone can assist me with this gridview problem
I have this Sql statement that outputs a gridview like this
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
* These columns are placeholders
I want to include a footer total that looks like
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
Final Total 4
Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.
I have a Gridview on my aspx page. On my page_load event I check for a record in the database, if the record exists for that row in the gridview I would like to add a new column in the same gridview and add a button control to it. This adding of new column in the Gridview should happen in the codebehind (c#). see the code I wrote for this, but when I run it, it does not create any column on the gridview page.

how to setup a edit option in the drop down...
Example:
I have a drop down for 6 colors...and user didn't find the color which he wants...can I place a last option as new or Edit or something which allows the user to enter the color he wants in the dropdown or change that drop down to textbox to enter data... If this is possibly then how can i capture those values in the code behind...

It resides in a html table, what i would like to do is on a keypress, such as the "insert" key, i would like to add the same control again directly on the next row, I have used programs that do this, but for the life of me can't figure out how its done...
View 1 RepliesI 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:

View 1 RepliesI have seen code for adding columns at runtime but here is another scenario for you. I am using a SQLDatasource control for my gridview. And the data returned can have different columns based on the filter meaning one time I may have a column A1, A2, A3 and another time I may have A2, A3, A4. Is there any way I can look at the columns when it is binded at the beginning and add the columns first?
I really need to use the SQLDatasource though because I am connecting to an AS400 and it is using a connection already made in the webconfig and do not know any other way. I do if it was MSSQL server but not this.
I am returning an IList to my model of data about users. I want my end users to be able to select which columns they want to see.
I know I can do this with a huge "if statement" however, I know there must be a better way. I have created an Enum with the column names. I feel if I could take the IListItem.EnumName I would be set. However, I'm not too sure on how to do this.
I have the default membership table that was added automatically, then just used server explorer to add more columns, like FirstName, LastName, etc. In my code I can access all the default columns, but not the ones I created. Any thing special I need to do?
Here is how I access the table. using user. gives me all columns, but the one I created.
string userName = User.Identity.Name;
MembershipUser user = (MembershipUser)System.Web.Security.Membership.GetUser(userName).ProviderUserKey;
I am using subsonic in asp.net forms C# and I have an instance where I need to loop through a recordset and for each one call the Database to get specific information from a view about that record.
in this instance it is a venue, loop through and for each venue I show there spend and there budget, but I am at a loss as to how I can say use a gridview, execute more code on each row and then add more columns to that row.
just as an update i have been playing with the idea of something like this:
DataSet ds = new DataSet();
ds.Tables.Add(LinqToDataTable(club.All().Where(x => x.level == 1)));
ds.Tables.Add(LinqToDataTable(ViewBudgetSpend.All().Where(x => x.periodfrom == curperiod)));
DataRelation relation = new DataRelation("budgets",ds.Tables[0].Columns["clubId"],ds.Tables[1].Columns["clubid"]);
ds.Relations.Add(relation);
still working this out though.

This is the code which I am using for altering the number of columns in a table in the DB. so with this code i am able to add new coulmns dynamically. Now my major requirement in this is to obtain the headercount from the user( say "telephone number" and "language") and based on it generate the columns dynamically in the table in the DB.
I have a stroed procedure which is mapped in myEDMX file under EntityContainer >>Function Imports. When I add or remove a column from the stored procedure, I am not able to remove the old columns from the model. I right click on the stored procedure in Model browser and got to Edit Function Import. The return type is complex.
I select "get column information" and get the updated return fields but can not update the collection. It will work if I click on "Create New Complex Type" but it will generate a new name for the collection and the old collection is still in the mode. I even tried deleting and adding the stored procedures and can not get it to work. I can only edit the edmx.cs and the XML to remove it but there is got to be a better way.

I am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
