Web Forms :: Read File From Sql Server Varbinary (max) Field?
Dec 20, 2010I have a function that will take a file uploaded by a user of my system and store the contents of the file into a varbinary(max) field in a sql server database. I then display the filename of the file in a data grid for the user to see as a link button. When the user clicks on the link button, I want the file to be read from the database and served out to the user as a prompt to download the file. How can this be accomplished? The upload is fine, it is the download I can't figure out. Here is what I have so far.

I get the download to prompt, but it is showing the name of my .aspx page as the file to be downloaded.

Sep 10, 2010I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?

View 4 RepliesConditionally Make A DetailsView Field Read - Only?
Jan 26, 2011Say I have a DetailsView with a bunch of fields, and I want only certain kinds of users to edit a few of them. They're too few to split them into another DetailsView, so what I'm thinking is to find some way to only allow a user to edit them based on some code-behind logic, effectively making them read-only at will.
I feel it's important to mention that the fields are both TemplateFields, not normal BoundFields with ReadOnly properties. For some reason the required functions don't jump at me from reading the documentation. Oh and I need eveyone to see their specific values, I just want to restrict edit access to them.

Web Forms :: Field Validators Doesn't Work When Field Is Manipulated With Ajax
Sep 3, 2010I have defined a field validator that works fine on normal behavior on a page:
<asp:RequiredFieldValidator runat="server" ErrorMessage="errroooorr" ControlToValidate="TextBoxHouseNumber" Display="Dynamic"></asp:RequiredFieldValidator>
Now if I dont insert any text in the TextBoxHouseNumber field, and push submit, the FieldValidator fires as it should. But if I now click a button that automatically fills the TextBoxHouseNumber with text from a Jquery/Ajax function, the field validator still shows. Itīs like "Hey, the user hasnt made any changes to the textbox, so I wont bother check it".
Forms Data Controls :: A Required Input Field DropDownList If Old Records Have Null In This Field?
Apr 1, 2011I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".
Web Forms :: Required Field Validator Not Catching Empty Field?
Feb 3, 2010I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
