i have an SQLdatasource in my page
i was trying to modify it as:
SQL.SelectCommand = "Select * from " + TXT_Tabella.Text;
because i want update dinamically my sql server tables but ,every time i am going to sort, or change page the selectCommand returns as before!
viewState is true! how can i have an SQLdatasource dinamyc by tableName? and how this problem occurs?
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:
<!-- Start MainContentRegion -->
<h1>Useful Links</h1>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"

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">

how to query the system date in selectcommand in gridview without using the codebehind. using c# .net
my code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" SelectCommand="SELECT * FROM tablename where date_today = <SYSTEMDATE>" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName
%>"
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?
View 2 RepliesI 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:
[code]....
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'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:DropDownList>
<asp:SqlDataSource ID="dsPopulateUpdateDatum" runat="server"
ConnectionString="<%$ ConnectionStrings:GAMSYSTEMSqlServer %>"
SelectCommand="SELECT DISTINCT(UPDATEDATE) FROM [messages] ORDER BY UPDATEDATE ASC ">
</asp:SqlDataSource>
And I use this in the gridview datasource:
<asp:SqlDataSource
runat="server"
ID="dsGridview"
ConnectionString="<%$ ConnectionStrings:DBSqlServer %>"
SelectCommand = "SELECT * FROM [messages] WHERE AND UpdateDatum >= @UpdateDatePar ORDER BY UpdateDatumDESC"
>
<SelectParameters>
<asp:ControlParameter Name="UpdateDatePar" ControlID="ddlUpdateDate" PropertyName="SelectedValue" Type="string" />
</SelectParameters>
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.
Suppose i am having 25 character length string and I want to bind only first 15 character of that string into the label control.
<a href="[URL]" >"<span class="name" style="text-align: left; font-family: Arial; color: #0094DA; font-size: 14pt">
<%#Eval("Name").ToString().Length >= 30 ? Eval("Name").ToString().Substring(0, 30) : Eval("Name").ToString()%></span></a>

View 2 RepliesCurrently, I have long script which does major processing and then puts data into temp table.
Finally I read data from this temp table to show on the chart, based on user's selection of parameter. So I can divide my query into two parts and while I am researching this,
Is it possible to do processing in one Datasource and read table from second datasource?Is it even possible?
If not, what is recommended method for this (breaking large processing into small one)?
There is a table contains thousands of records. when I run this query:
[Code]....
The application stucks...it takes too much time to execute this query...
What might be the reason for that?
Linq code sometimes takes too long to execute
View 4 RepliesI have a site that calls a long running stored procedure that eventually times out the UI. The procedure simply runs some logic in the database, and kicks of a secondary process. No data is ever returned to the UI, so I don't need the UI to wait for anything.Is there a way to call the stored procedure from the UI and move on without having the UI having to wait for the store procedure to complete?
View 4 RepliesI installed MS SQL Express 2008 with Advanced Services including Management Studio 2008. When I connect to the SQL server of my provider (shared hosting - one SQL server for many customers), it takes very long (up to serveral minutes) until all DBs are displayed in the object explorer (from which I then have to choose my DB). Somebody told me, the long waiting time occurs because Management Studio first checks rights (whichever rights that may be) with every DB that runs on the server.
But in Management Studio 2005 the behaviour is different - the DB Tree in the object explorer expands immediately! No waiting time! Does anyone know a solution for this? I don't want to install two separate versions of Management Studio just because of that!
I have an application which imports data from csv to sql server 2005. It is taking long time to import data from csv to sql server 2005. it has a timer. on tick of timer, I am checking if current rown in csv exists in database. If it exists, It is not added to sql server otherwise, It is added that row to sql server 2005. Also, In page load, It checks on each tick, whether user is logged in or not. it adds value to log file that user is logged in. How can I optimize this ?

I am working on a website hosted with GoDaddy, SQL Server 2005. I have a table in my SQL Server database with a full-text index. On my website, a user can type in search terms and the terms are then passed to a stored procedure in the database which performs the search. The first search takes about 45 seconds to get results. Subsequent searches return results immediately. I found a description of this problem in a Microsoft knowledgebase article:http://support.microsoft.com/kb/915850/en-usGoDaddy tech support says I need to purchase a dedicated server to make the changes suggested in this article.Surely there is some other solution. Does anyone know how to avoid this delay without changing the server configuration?
View 1 RepliesIn my app, I use the built-in membership for managing security. If I log into my app using my iPad or iPhone, I see some long string preceding the ReturnUrl. Here's an example of what it looks like: [URL] At that point, I'm at where I wanted to go but I'm logged off. If I try to go to another secure page, I have to log in again. And the cycle starts all over again.
View 2 RepliesI have a large(ish) text-box on my page that needs to hold a website URL. The text-box is reasonably wide however most URLs will not fit in on a single line. I want the website address to wrap a single line like this:

Does anyone know how to automatically wrap a string that does not contain line feeds / white space? (Yes - Wrap is set to true!)
