I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action.
[HttpPost]
public ActionResult Manage(ProductOptionModel DataToAdd)
{
if (!ModelState.IsValid)
{
return View(DataToAdd);
}
var ProdServ = new ProductService();
if (DataToAdd.ID != 0)
{
//Edit Mode.
DataToAdd = ProdServ.EditProductOption(DataToAdd);
ViewData["Message"] = "Option Changes Made";
}else
{
//Add
DataToAdd = ProdServ.AddProductOption(DataToAdd);
ViewData["Message"] = "New Option Added";
}
var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID};
return View(RetModel);
}
So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. I have debugged the code and checked that the RetModel variable is empty.
public DataRow GetItem(ENTITY_TYPE EntityType, long EntityID)
This fetches a row and returns it. Pretty simple.
However I can't test in the method to see if the row was fetched, as the method has to end with:
return ds.Tables[0].Rows[0];
If the row wasn't fetched, this errors as there is no row at position 0.
I can't do this:
DataRow dr; if (ds.Tables[0].Rows.Count == 1) { dr = ds.Tables[0].Rows[0]; } return dr;
.. because then I get an error that I can't return an uninitialised variable (dr).
I can't stipulate what the columns are and return a "blank" DataRow as far as I can see, because it's dynamic so I don't know what the columns will be. There doesn't seem to be a way to instantiate the DataRow return var except by assigning, er, a DataRow. Which I may not have.
I don't really want to switch to using the ItemArray and pass arrays about, I'd rather just pass the DataRow object as this is in a loop which might process a lot of rows.
Ok so I am trying to setup a WCF web service. I thought I had my .svc and webConfig ready to go, but when I hit this service all I get is a blank page.
I'm new to WCF and this is definitely a rookie question. Why does my browser show/return nothing when I type this URL: http://localhost/service.svc/root, using the code below. I was hoping I would see an xml respone like: <double>56.78</double>. service.svc
I'm having a lot of trouble with this, and all the examples that I've found online tell me different things, so II added a DataSet to my project and added my database table to it. (DataSet should be ready)I added a CrystalReport to my project and in the Details section, I right clicked and chose "Database Expert" under "Database". I expanded "Project Data" and found my DataSet...I selected my table and added it to the "Selected Tables" list.In the CrystalReport designer, I used the "Field Explorer" to add 5 of my database fields (just for testing purposes). The report added their names to the "Page Header" and the fields to the "Details" section.On some button click, I use the following code to show the report:
[Code]....
where "conn" is my global SqlConnection.where "CrystalReportViewer1" is obviously the viewer I have put in my aspx page.where "DataSet1" is the DataSet I created and holds my table.where "CrystalReport.rpt" is obviously the report I created.and I used the following code to make sure that myDS actually was loaded with the data:
[Code]....
So the DataSet is definitely loaded with data, the CrystalReport is found (because before I was having trouble with loading into oRpt), and no exception is being thrown because the "Catch" section is never reached.I'm sure it's something dumb I'm doing, but does anyone have any suggestions? I know if I can figure this little problem out, I can expand it to the more complex things I want it to do. But currently, I can't get anything to show,
Very new to C# although I have alot of older coding experience. Not much object orientated programming though. Anyways, I have a .net program I'm working on, basically to work on my skills although it will prove to be useful. I am keeping track of my work schedule. Currently, I am populating a datagridview from a sql 2008 express db. My columns are: date worked, hours, paid, and paidon. What I want to do is add an empty row whenever the date corresponds to a date that is "Monday". My goal is to line break every week. So that each work week (Mon-Sun) is seperated by a blank row. I would rather not actually have this blank row in the database. I would like the gridview to do this on the fly. Here is my gridview code in my default.aspx file:
I have a GridView bound to an ObjectDataSource. Most of the columns are directly databound, however one column is not - it's value is determined in code. The value is being calculated correctly at the RowDataBound event, however when there is more than one data row in the GridView, the calculated fields for all of the rows is blank, but the top row displays the bottom row's calculated field
I found code [URL] that allows multiple-row inserts, and tried to convert it to vb.net. I can't get the blank grid with 5 rows to show up -- for some reason the datasource won't bind.
is there a way in crystal report to remove blank space between two data field for example
Field 1 Field 2
how do i make it the distance between Field 1 and Field 2 become closer and look like this
Field 1 Field 2
without changing the position of the Field 2 in the report design... i need this cause the data in Field 1 is different for each user and i need the Field 2 to have a smaller font size than the Field 2 so i cant use formula since formula only allow 1 font size.
As per database designer's logic if there is no data in above field then he replace empty to 0 and in my gridveiw 0 is displaying whereever the cell is empty.
Now I just want to replace 0 to empty.
One more thing that if it displays 0 in a hyperlink Field then it should not be displayed.
The data binding is done manually in the code behind, which means you have to manually write the onpageindexchanging in there too. Normally that's done like so:
[Code]....
When you click to the next page on such a page, it is only blank if you have if(!Page.IsPostBack){} around your manual data binding. Well on this page with multiple gridviews I don't have that. But it's still blank when you click to the next page.
While uploading excelsheet to datatable and bind it to gridview it will check blank data in excel sheet and when it will bind to gridview,the row in which blank present that row will be in red background color and the other row will occur in normal back color.
my gridview column coming from database dynamicly it may be 10 or it may be 20. i added a blank row in grid throughdata table . i want to write something in this row and change color.
GridView: grvResultPrimary Key: FLTIDTextBox: txtRemarksThere is a button named btnAdd in the FormView named FormView2.txtRemarks is outside the form.The scenario is that if user wants to add a record with empty textbox and click btnAdd then how to restrict user to add empty row to gridview?I have tried Validation by controling txtRemarks but it is not helpful for me because in the page there is a FormView1, FormView2 and grvResult.If I am applying validation then all other updation methods of FormView1 and grvResult are disturbing.Simple is that I want to give option to user that without empty data using txtRemarks, user can enter data to grvResult.
I have searched all over the internet and there are just too many solutions that basically is not working for me right now unfortunately. i just want to display my gridview header and I dont want to add a blank row in any form.
I'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.
I get a message like this if I change the "State" field to blank when doing an update
The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.
I have a dropdown box control, populated by an Access data source, and linked to a form control which renders an appropriate record detail when a selection is made. All works as intended. My issue is that each rendering of the page shows the dropdown box carrying the link to the first record, with the detail portion of the page already complete with the information for that record.
I'd much prefer that the dropdown box would carry some text, like "Click to select..." leaving the detail part of the page empty at the first iteration of the page, allowing the user to pick the first record. I can't seem to find any way around this problem with the control or the data, unless I add a record at the top of the file that carries the text.
I am trying to update the value of a cell in a gridview at the same as conducting a post back to the DB....
Currently I am not able to even find teh control to puchthe data back to the cell, do I need to update the DB first then let the query read the updated record?
[Code]....
How can I get the new birthdate back into the ("studentDOBLabel") on the template at the same time I update the DB?
I want to make a link in databound data which is stockQtt. How can I do that? and I want target is blank and the link page is AdjStock.aspx below is coding.
but when I click on imagbutton it didn't do any thing..I put break point and checked @ID value that was "_page" and I checked IMG Delete. Command Argument value was "".I used .CommandArgument for Linkbutton in other page I don't know is it right to use it for imagebutton?
