I wish to know if it is possible to directly reference a control's value within an SQL Command? I remeber seeing something that caught my attention at one time, but I can't seem to remember where I found it. I am just trying to see if this method could work without having to declare parameters. Here is a sample idea of what I am trying to use:

i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource();
sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString();
sq.SelectCommandType = SqlDataSourceCommandType.Text;
sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1";
string result = sq.Select(some overload that's stopping me);
I'm trying to programatically reference a FileUpload control which I have within an ItemTemplate. I get a 'Name FileUpload1 is not declared' error message. Code below:
Code is as follows:

Here is data binding expression (dropdown list is nested in gridview)

Code Behind has function which looks like

The whole reason for passing the reference is to save round trip to database and not to use SESSION
I'm customizing a NopCommerce store, and am using a gridview to display and sort the products. All that works well. I like how the external pager (user control) works with the gridview, with one exception -- it uses the hyperlink control, so I lost viewstate, which I need to retain for both the search page and to retain the gridview sort options. Based on the page selected (from the pager control), I query the database and rebind the gridview. So, I switched the user control to use LinkButtons instead of Hyperlinks. This is the sample code for one of the buttons:
[Code]....
I set a breakpoint inside the lbCommandClick method, but it never gets hit. Reading other posts tells me that I would have to add the dynamic controls in the OnLoad method, but since this all happens based on other data on the page (say search results), I don't think I can do it onLoad. However, the link buttons do work to cause a postback, and my viewstate is saved correctly. The only problem is that I do not know which button was clicked. I could check Request.Params["__EVENTTARGET"] onLoad, but that is kind of a hack -- I'd much rather be able to set the event handler in the user control and use the CommandArgument property. But, what I have tried so far fails.
Especially one that would allow me to set the EventHandler in the User Control? (e.g. OnlbCommand="PagerLBPageChange" )
I am trying to implement adding a new record using the Gridview footer.
I have an example that works finethat I got from [URL]
My situation is a little different .. as I am using master page and the Gridview is in a page derived from the master page.
I have tried:
Dim txtNewName As TextBox = DirectCast(GridView1.FooterRow.FindControl("NewName"), TextBox)
"NewName" is the ID of the textbox in the footer of the Gridview.
When I try referencing ... txtNewName.Text ... it returns a null value.
There must be some trick to referencing this .Text value when using the Gridview that is within a Content Place Holder that results when using a page that was created using a master page.
how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...
I am doin a project in asp.net 3.5 and sql server 2005. In my project it need a condition where i click a button and a .pdf page is directly open where the .pdf document are stored in server.
I can do the things but it show a opening box seeking open/save option.
I just want to open directly the .pdf page on clicking the button.
I have a page with one dropdownlist and one grid. when dropdownlist's selected index is changed i generate a BindingList with some data based on the dropdownlist's selected value. this BindingList is binded to the GridView with one readonly column (eg: Item) and one column for entering data (eg: qty).
i need the Qty column to directly editable (without pressing edit, then goes to edit mode). and update this values back to BindingList's corresponding Item when the qty cell's focus is changed.
I can directly use to read and display Excel or CSV files using asp web control(GridView, sqldatasource etc). I do NOT want to upload the file first to an sql database before reading them, I just want to read the files directly. I am using asp.net 2.0 and c#.
View 3 RepliesI'm not even sure if this is the correct approach for this -
I have a DB that stores information, as well as a location to where images are stored
ie ProductImage = ~/ProductImages/BulkRetail.JPG
I'm using a repeater to list all the products, which works fine for all the labels I use but not for the image location. I'm using something like this, but it doesn't work:
<asp:Image runat="server" ImageAlign="Left" ImageUrl='<%# Eval("ProductImage") %>' />
can you please help me to brainstorm the possible causes of this error. I've got a paged repeater with localisation bound programitcally to an sqldatasource using a stored proc. I can post code if needs be but it's rather long. I'm looking for typical causes of this error + will make note for future reference!

Im not sure why we have SiteMapProvider and SiteMapDataSource. I mean i know we can have different providers ( like XmlSiteMapProvider, SQLSiteMapProvider etc) but then why there is SiteMapDataSource added in between the Server Control and these Providers? why cant we directly assign SiteMapProvider to TreeView or Menu Control? The way it works right now Menu Control ->SiteMapDataSourve->SiteMapDataProvider

I started a C# web project in Visual Web Developer. I dropped a grid view in with designer and connected to my remote SQL database with the designer dialog based wizard. All is well there. I have in my program also a textbox where a user enters a zip code and clicks a button 'search'. When the user clicks search I want to run the SQL command "select * from flat_list where zipcode='userszipcode'". In other words the userszipcode is dynamic and different every time. It is my understanding I should use a SQLDataSource object but I do not know how.
