DataSource Controls :: SqlDataSource : Make Condition Only If Data Is Not Null?
Feb 21, 2011
I have a SqlDataSource connected to database and use a parametrized query to fetch out data.Query has got a very large varchar field on which i have to perform a search.To make search, i have 2 combobox and a textbox organized in this way
MAIN CATEGORY (combobox)-> CATEGORY TYPE(combobox) -> MODEL(textbox).
Based on main category choose, category type is filled from database. At last, it's added a "nothing" combobox item.Now i should search into big varchar field adding category type condition but, if nothing is specified, i should make identical search like all combobox value are selected. How should i, in your opinion, make this using SqlDataSource?

In following SQL query: SELECT DISTINCT CodeID, CodeDesc FROM Faults.TblFltClearCodes AS TblFltClearCodes
I am getting a list but there is no null value.Within this query I would like to get only one NULL value at the top and then the list.How to do this? Explicitly I am not allowed to give a null value in the table in DB.

what i would like to do is when the value of my sqldatasource is returned, then if it is null, run a code, in my case, redirect them to the login page, heres my code:
string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString;
string insertSql = "SELECT * FROM LoggedInUsers WHERE UserId = @UserId";
using (SqlConnection myConnection = new SqlConnection(connectionString))
[Code]....
Now what i would simply like to do is, if the select statement searches the database, and the result is not found, the simply redirect them to "register.aspx"

I have a FormView which is bound to an SQLDataSource. When a user clicks on a save button the form, I need to write any changes made to the FormView back to the table.
I have a Stored Procedure on my MSSQL 2005 database that should be executed when the user clicks on the save button.
It appears the Update is firing, but when I trap the DbCommand object in the SQLDataSource's 'Updating' event, all of the parameters that should be passed to the Stored Procedure are coming through as NULLs. Consequently, the Stored Procedure isn't updating anything.
In the click event of the save button I'm explicitly firing the SQLDataSource's Update method:
[Code]....
The parameters in the SQLDataSource <UpdateParameters></UpdateParameters> section appear to be correct.
Can anyone give me an idea on what to investigate to figure out why it appears the Update is only picking up NULLs?

I have a gridview which I connect by C# and SqldataSource. I use asp.net 2.0 - 3.5.
I want to parameterized the queries and how do I do this in the C# file ? how do I set the selectparameters in C# ?. I do not want to do this in the aspx fil.
My code in C# is:
SqlDataSourceMachineName.SelectParameters.Clear();
SqlDataSourceMachineName.SelectCommand = "Select MachineName from tblMachine inner join tblLocation on tblMachine.MachineLocationID = tblLocation.LocationID where tblLocation.LocationName = 'New York' and
tblMachine.StatusID = '1'";

In my grid I have three fields: Action date, type name and TypeId. I want to make the Edit linkbutton disabled when the type name is either 'Accepted date' or 'Received Date'. I can do it if there is one condition by the following code, but I can not pass both.
<asp:LinkButton
ID="lbEditAction"
runat="server"
CausesValidation="False"
CommandName="Edit"
CssClass="LinkButton"
Height="19px"
Text="Edit"
Enabled='<%# Not "Accepted Date".Equals(Eval("ActionTypeName")) %>'
Width="39px"></asp:LinkButton>
Is there a way to do this?

i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?

I want to retreive some data from an SqlDataSource using it's Selected event I've tried
DataView dv = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty)
but here it's going into in infinite loop and then it gives me an StackOverflowException error in ASP.Net Development Server (my dev machine) and if I publish to IIS it requires me an user name and password to connect to server and gives an InternetExplorer error "Sys.WebForms.PageRequestManagerServerErrorException. An unknown error ... status code returned was 400. The SqlDataSource is in an UpdatePanel. Maybe this is why I get this.

I know this sounds odd. I have a SQL DB that I am pulling data from. I have to some math functions to get a percentage. So I am pulling all the data in my code and building a data table with the results. I am then trying to pass this into a chart control that I have, but it fails because the data source is not correct for the chart control. I know that the chart control will accept a SQLDataSource control as a data source because a built a example with it before using it in my project.So my question is how can I use the Data Table as a data source for a SQLDataSource Control? Or is there a way I can pull the data from my DB andapply the math needed in a stored procedure or something similar that I could create the procedure on my SQL server then add a SQLDataSource control to my page and use the stored procedure as the source for the SQLDataSource Control.

I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:
[Code]....
<truncated>
What I want is to grab the screenshotId from the SqlDataSource when the usp_GetOrderDetails stored proc gets called and populate it into a field on the page called screenshotId. I then want to use this screenshotId to get an image from the database based on Id. populating the screenshotId field. How do I do this - do I need to have something like OnDataBound or something like that?

Is there anything special you have to do to retrieve Filestream data using a SqlDataSource? I'm using VB and have this as my sqldatasource:
<asp:SqlDataSource ID="SqlDataSourceReadPD" runat="server" etc...
SelectCommand="SELECT [PDIPAttachment] FROM [PositionDescriptions] WHERE ([CP_IDString] = @CP_IDString)">
<SelectParameters>
<asp:Parameter Name="CP_IDString" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
PDIPAttachment is a FILESTREAM column in my table called PositionDescriptions
and this is some of my VB cod:
Dim dv As DataView = DirectCast(SqlDataSourceReadPD.Select(DataSourceSelectArguments.Empty), DataView)
Dim dr As DataRowView
For Each dr In dv
Dim data as Byte() = System.Text.Encoding.ASCII.GetBytes(dr("PDIPAttachment").ToString())
Next
The Filestream data has a PDF file in it, but what I"m getting back in "data" are 13 bytes consisting of: "System.Byte[]".
