Forms Data Controls :: Checking A Value In A Method Before It's Inserted (Formview C#)
Nov 18, 2010
I've been pickling my brain trying to do this for a couple of days but to no avail. I have the following in "FormView1" which I'm just using in insert mode:
I'd like the contents (i.e. whatever the user wants to insert) to be passed to a method where it will be checked against any existing values in the database.
I have a SQL 2005 database table with a column that has a datatype of nvarchar(255). It holds URLs.I created a FormView to edit records in the SQL table. The value for this column gets put in a TextBox in the FormView.When trying to edit the record, any text placed in the textbox gets truncated at 50 charactersI checked the TableAdapter in my dataset, and in the properties for that column, it has "255" for MaxLength.
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminsertedevent?
I'm trying make FormView insert a new row into a database table via a stored procedure.My code runs without error but nothing appears in the database table.
I have a FormView that is loaded with a records from my DB. Some of the fields may be blank or null. I am trying to check the value of some of the text boxes to verify that the user has updated the fields prior to allowing a DB update from the Edit Template.
I can not seem to get the correct syntax on the if statment to check the value of the text box....
It is  working on button click , becuase i when store the values from datalist into my database , the values got inserted .. but when i am trying to store those value in temporary datatable its not working
[WebMethod] public static ProductDetails[] DisplayMessage(string name, string price,string obj, string id) { string emailid = HttpContext.Current.User.Identity.Name; ; string date = DateTime.Now.ToString(); string s = HttpContext.Current.User.Identity.Name;
I have a series of classes that loosely fit the following pattern:
public class CustomerInfo { public int Id {get; set;} public string Name {get; set;} public class CustomerTable { public bool Insert(CustomerInfo info) { /*...*/ } [code]...
I have a Customer database table with a text field named customerPicture with the name of the JPG file.
I have made a Customer Entity class with the LinQ to SQL Designer.
I also have a FormView displaying Customer instance binding with a LinqDataSource.
My problem is:
I want to make some modifications when some control want to bind the customerPicture field.
For example, when my FromView want to show the field customerPicture I want to return not only the JPG file name, I want to modify this string to add the complete file path and perhaps resample the image to a determinate width and height.
I know that is posible to defeine a partial class named Customer to implement certains partial methods, like OnCustomerPictureChanged(), but I dont know how to do this.
If I make, in this Customer partial class, a new method, for example getResamplePicturePath(), how could I invoke it from a FormView?
I have method that I call which needs to find all the panels in the page but it fails. I have another method that was created by the VS has the traditional paraeters such the object sender, EventArgs e that the similar code works fine but the (simplyfied) code below. It is clear to me that these parameters contain information that makes one method work while the other not, but I don't know why.
The code breaks on the last line of code: _pnlAssetInfo = (Panel.....
Is there an equivalent of the GridView.RowDataBound event for the DetailView and FormView controls in ASP.NET 3.5?I need to manipulate data after Selecting it from my database, but before it gets presented to the user. I've read the documentation but I think I've missed something because I can only find FormView.DataBound which is called after the entire control has been data bound. Something like an ItemDataBound event would be what I need....?!?
Is there one simple test that a person can do that covers all options where there could be a null, or "" value. When I google, I see so many options. I see:
if txtBox1.text IsNot nothing if txtBox1.text.toString isNot nothing if txtBox1.text <> "" if txtBox1.text.toString <> "" if isNull(txtBox1) Is there on test that can cover them all?
I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?
I have gridview, and in this gridview, I insert a new row dynamically depending upon a value from the database all the way down the table. Even though this is all working well, I need to access a number of controls that I added to the inserted row. Namely, a checkbox and label. When I try to access these controls, I am getting an error message - object not set to reference. Then I tried saying "Gridview1.Rows[rowIndexVal].Cells[1].Text = myTextVal", but what this does is to insert the value on a different row.
Therefore, I have two problems, which I am really desparate to try and solve:How do I access the correct row and control that I have added to my inserted row, andBecause I have a checkbox control on my inserted row, which has an event associated with it, how do I get the selected row the user clicked. When I try doing this using FindControl, I always get a row index of zero.I am using Table object and TableCell to add a new row dynamically to the gridview, and then using ColumnSpan to make it fit the number of columns in the gridview.
I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack) { //Initialize SetupDate to today. TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate"); setupdate.Text = DateTime.Now.ToShortDateString(); }
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.
I am working with GridView, When huge amount of Data is inserted in the GridView its columns became very thin all tall, however I want to Display the Gridview with Fix size and if the Data is hugeit only display the starting few words of Data.in other words I want to use gridView same like the GMAIL account where Data Display like this. .
I am using a Listview with InsertItemTemplate bound to a LinqDataSource with a child table in the ORM datacontext. This table has a relationship with a parent table in the OR/M datacontext. The record is to be inserted in the child Table. The parent table is bound to dropDownList in the InsertItemTemplate to provide a user friendly name. Using the ListView ItemInserted event in debug, I can follow the execution and no errors occur BUT no record is inserted. I confirm this by a showing all Table Data in the SQL Mgmnt Studio. The child to parent table seems to be causing the problem because when I delete the relationship in the OR/M .dbml , I am ABLE to insert records. I am using Scott Mitchells' Using ASP.net 3.5 ListView with Data Pager controls: Inserting Data as a model. I can provide code if required, but what is going on with the deleting of the relationship between child and Parent.
I'm coding with VB.NET and have a webform that includes gridview. The gridview captures data via a db view. Also the view includes all the parameters of the tables.
The problem is: when start program, there is only 2 rows seen on gridview. then i can insert something successfully. And when i checked from db i can see the new data. But in my form, newly inserted data doesn't seen. Even i restart the whole program, gridview always shows only 2 entries.
I am currently binding my Detailsview and Gridview together by a "ID" field selectedvalue "1". Which works great except for the fact that I don't want the user to have to go down to the gridview and select the page and then the record to view it in the detailsview.
I have 1 sqldatasource for detailsview and another sqldatasoure for the gridview. Both have the exact same select statement.
I want the gridview and detailsview to automatically display the last record inserted not the first record in the table.
This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.
after a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e. I'm looking for a kind of automatic 'postback' bringing my just entered data back
I have an object data source control. and to insert the control I add the object to the database then call databing on the gridview the DataSource control is bound to.
My question is - how would I know where the newly added row is? I can'y go by id, because the dbase creates the id.
I'm thinking maybe last data key, but based on the sort that would be accurate.
