What Dynamic SelectCommand In SqlDataSource
Nov 17, 2010
I have a DDL with 2 options: "Trainer" & "Observer." I'd like to use the selection from that DDL to reference a field in the SqlDataSource SelectCommand.
There are 2 fields in the table that may be referenced in the SelectCommand:
"Trainer_Oracle_ID" & "Observer_Oracle_ID." I'm trying to do something like:
WHERE @Oracle_ID_Type = <%=DropDownList_Oracle_ID_Type.Text%>_Oracle_ID
i.e. User selects "Trainer" and the SelectCommand references the field called:
"Trainer_Oracle_ID."

With asp 2.0 and vwd 2005, I have a page with a radiobuttonlist, textbox and gridview with edit/delete. Using the radiobuttonlist, the user selects a search type and then enters the criteria in the text box. the click event of a submit button checks the rbl.selectedindex and chooses a sqldatasource.selectcommand with the where clause getting its criteria from the textbox. The gridview loads the data, but the edit/delete are not working. Code and relevant markup is below

I have an ASP.NET 3.5 web form with a DropDownList bound to a table of company names in a database. I also have a data bound GridView which I would like to update with data from the database depending on the company name selected in the DropDownList, so that the SelectCommand for the GridView's SqlDataSource is:
SELECT Registration, Telephone, Profile FROM {CompanyName}_VehicleData
Where {CompanyName} is whatever is selected in the DropDownList. I've used the Command and Parameter Editor to create a ControlParameter pointing to the SelectedValue of the DropDownList, but I don't know how to write the SelectCommand query to concatenate the parameter to '_VehicleData'.

I have a GridView bound to a SqlDataSource with a default SelectCommand defined as such:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" DataSourceMode="DataSet"
ConnectionString="<%$ ConnectionStrings:MyConn %>"
ProviderName="MySql.Data.MySqlClient"
SelectCommand="select * from blah blah" />
There are cases where I have to change this query dynamically at runtime, so I do the following:
SqlDataSource1.SelectCommand = sql; // 'sql' is the new query
GridView1.PageIndex = 0;
GridView1.EditIndex = -1;
GridView1.SelectedIndex = -1;
GridView1.DataBind();
updatePanel.Update();
This works just fine actually, but when I click the pagination controls, the result set defaults back to the SelectCommand defined in the SqlDataSource1.

I have a SqlDataSource setup in the markup on my page. After some new requirements, I am trying to find a way to modify the SelectCommand before the data is filled for the first time. The SelectCommand below will now be used by default since we'll always have the first param. I am faced with a need to modify the SelectCommand though, adding a second session parameter along with it. I tried to override the OnInit method but it didn't seem to help...it still used the default query. Is there a best way to accomplish this? Here is the section of markup I am referring to:

In an asp.net 3.5 web app, I have a page with the following markup/code (this is the brief version, but I believe I got all the relevant info).
[Code]....
The form contains 2 different record types, accessed using the paging controls, depending on the ParentSR field; a parent SR will be something like '1234' while its sub-record will be something like '1234.1'. There are only a few differences in the fields used between the 2 different record types and that is why they are stored in the same table. However, the activity depends on the record type. When browsing from the parent record to the sub-record, the itemtemplate loads fine (notice in the formview's datasource
query, that the sractivity_id field is being pulled along with the subquery value). But when going to edit the record, the page throws an error:
System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentOutOfRangeException: 'ddlActivity' has a SelectedValue which is invalid because it does not exist in the list of items.
If i click 'back' and retry, it may take 3 attempts, but then the edittemplate will load just fine. I should also point out that this error does not always occur. I've been trying to figure this out for a couple months and it is driving me nuts, mainly due to the fact that I can't reproduce the error in development--it seems to only occurr in production. Anyone with any thoughts on what is going on?

I have a database with two columns: Retailers or Traders. A row can have only one of them with values while the other must be 'Null'. Both are nvarchars kinds. What I am trying to do is to show data if a radio button is selected for either Retailer or Trader. So I constructed a SelectCommand statement which is getting column names of either 'Retailers' or 'Traders' as a parameter but the SelectCommand statement still returns all records. What can I do?
<asp:SqlDataSource ID="dsSearchResults" runat="server" ConnectionString="<%$ ConnectionStrings:AdoFabricsConnection %>"
SelectCommand="SELECT Name,Address1,City,State,Zip, Telephone, Email_Address, TO_THE_Trade, Retailer,

I have a page has Listview and Datapager inside UpdatePanel. When I refresh the new SQL results and bind by pressing link buton outside of the update panel, I get correct results. (get new SQLselect statment, rebind to listview, update updatepanel)
However, the SelectCommand is not bound right or some other reason, if I press datapager, I won't get no results.
I'm guessing it's caused by not passing new dynamic selectcommand since my datapager and listview works first update.

1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

I am trying to pass a variable within a selectcommand statment in ASP.NET and I have researched online how to do it but I can't seem to find a way to do it...What I am trying to do is write a code for a web page that will display a page with useful links on it where the links are separated into different topics and where everything is dynamically grabbed from a database. This is what I have so far:

I build a DetailsView and assigned datasourceID= SqlDataSource1
I bulid select command at runtime.
string selectcmd = "SELECT * FROM CDInfo WHERE CDID=@id";
SqlDataSource1.SelectParameters.Add("@id", Request.QueryString["id"]);
SqlDataSource1.SelectCommand = selectcmd;
//The only problem is that I try to call the select method
//but the compiler tell me I have to add a DataSourceSelectArguments
SqlDataSource1.Select();
//I don't know what argument to add, so I put DataSourceSelectArguments.Empty
// But it says variable "@id" must be decleared
//I don't Know what's going on.

I have a question related to <asp:SqlDataSource's SelectCommand. How to pass a querystring like <%# Eval("PhotoID") %> in the selectCommand. The whole frontend code is attached. I put
<%# Eval("PhotoID") %> and the photoid gets printed in the page.
<%# Eval("PhotoID") %> is the current displayed picture's PhotoID.
I want to pass this PhotoID or I want to pass <%# Eval("PhotoID") %> to the select command dynamically. I have tried the following approaches:
1) <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:aspnetdb %>" SelectCommand="SELECT UserName, commentDesc, uID FROM photo_comment_view Where pID = @pID"> <SelectParameters><asp:Parameter Name="pID" DefaultValue="7" /></SelectParameters> </asp:SqlDataSource> The above works but it gives only information about PhotoID 7, but there are other photos; How to set pID's value to <%# Eval("PhotoID") %> in ASP .NET's frontend page? then I also tried,
2) <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:aspnetdb %>" SelectCommand="SELECT UserName, commentDesc, uID FROM photo_comment_view Where pID = <%#'Eval("PhotoID') %>"></asp:SqlDataSource> Gives Parser error: Parser Error Message: The server tag is not well formed.
What I should do so that I can pass current PhotoID to SelectCommand? The frontend code:
<%@ Page Language="VB" MasterPageFile="~/Default.master" Title="Your Name Here | Picture Details"
CodeFile="Details.aspx.vb" Inherits="Details_aspx" %>
<asp:content id="Content1" contentplaceholderid="Main" runat="server">

My SqlDataSource has no selectCommand defined in the .aspx page. Instead I define it in the code behind dynamically depending on some parameters that the user selects and then clicks a button to perform the query (custom search filters basically). The problem is that when I click on a different page in my dataPager, or I click to sort any of the columns the gridview becomes empty when the page refreshes. I did a check and the selectCommand becomes empty when the page posts back. Is there a way to prevent this from happening?
