DataSource Controls :: Modifying The SqlDataSource SelectCommand Prior To Loading A Page?

Sep 28, 2010

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 still used the default query. Is there a best way to accomplish this? Here is the section of markup I am referring to:

DataSource Controls :: Dynamically Changing SqlDataSource.SelectCommand From FormView.ModeChanged?

Nov 17, 2010

In an 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).


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?

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

Using Parameters To Configure The Table Name In An SqlDataSource SelectCommand?

Dec 15, 2010

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'.

Changing SqlDataSource.SelectCommand At Runtime Breaks Pagination?

Jul 23, 2010

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 %>"
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;

This works just fine actually, but when I click the pagination controls, the result set defaults back to the SelectCommand defined in the SqlDataSource1.

DataSource Controls :: Pass QueryString In SelectCommand From Code Front?

Jan 7, 2011

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">

DataSource Controls :: Maintaining A Custom SelectCommand Across Page Loads?

Feb 19, 2011

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?

DataSource Controls :: Filter - Select Date In Ddl And Use Selectedvalue In Gridview SelectCommand

Nov 7, 2010

I've got a gridview which works fine. I use dropdownlists which are filled with distinct values of the columns. So when I select an item in a drompdownlist the gridview refreshes based on the selected value. When I have a column which uses string values, I can start the filter with a default % value to use in my select paramaters. But when I have a date column, I can't use that. I use a datasource for the gridview and I prefer to leave codebehind out if this is not needed. Now I use >= in my gridview select to show all rows. but I want to use only = to make the filter work correct when I select a date in the ddl and use the selectedvalue in the gridview selectCommand

<asp:DropDownList ID="ddlUpdateDatum" DataSourceID="dsPopulateUpdateDatum"
AutoPostBack="true" DataValueField="UPDATEDATE" runat="server"
CssClass="selectinput" AppendDataBoundItems="true">
<asp:ListItem Text="All" Value="01/01/1900"></asp:ListItem>
<asp:SqlDataSource ID="dsPopulateUpdateDatum" runat="server"
ConnectionString="<%&#36; ConnectionStrings:GAMSYSTEMSqlServer %>"
And I use this in the gridview datasource:
ConnectionString="<%&#36; ConnectionStrings:DBSqlServer %>"
SelectCommand = "SELECT * FROM [messages] WHERE AND UpdateDatum >= @UpdateDatePar ORDER BY UpdateDatumDESC"
<asp:ControlParameter Name="UpdateDatePar" ControlID="ddlUpdateDate" PropertyName="SelectedValue" Type="string" />

DataSource Controls :: Dynamic SelectCommand Won't Be Passed After Partial Page Update?

Mar 11, 2010

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.

DataSource Controls :: Possible To Join With A #Temp Table?

Feb 13, 2010

I can join with a regular SQL table fine but this won't work:

SELECT normalTbl.*, tmp.fld1 FROM normalTbl
LEFT JOIN #Temp tmp ON tmp.joinID = normalTbl.joinID

All tmp.fld1 values are shown as NULL even though fld1 contains valid values and the joinID matches the normalTbl (when I call SELECT * from #Temp). If I do the same exact thing with a regular table, fld1 shows the correct value. What am I doing wrong?
