i want to ask how to i set variable in asp:sqldatasource in sqlcommand in asp.net c#....
This is my code
asp.net
<dx:ASPxListBox ID="lsAssignToko" runat="server" DataSourceID="SqlDataSource6"
TextField="NAMA" ValueField="ID" AutoPostBack="true"
EnableCallbackMode="True" SelectionMode="CheckColumn"

ConnectionString="<%$ ConnectionStrings:Ora2010 %>"
ProviderName="<%$ ConnectionStrings:Ora2010.ProviderName %>"
SelectCommand="SELECT ID, NAMA FROM REF_TOKO WHERE ID IN ( :inTOKO ) ORDER BY NAMA">
<SelectParameters>
<asp:SessionParameter Name="inTOKO" SessionField="inTOKO" Size="200" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
c#
string dummy = "";
string data = "";
string inTK = "";
string inTOKO = "";
//string inTOKO1 = "";
int pot;
for (int i = lsToko.SelectedItems.Count - 1; i >= 0; i--)
{
string tok = lsToko.SelectedItem.Text.ToString();
data = lsToko.SelectedItem.Value.ToString();
dummy = dummy + "" + data + ",";
int index = lsToko.SelectedItem.Index;
lsToko.Items.RemoveAt(index);
}
if (lsToko.SelectedItems.Count <= 1)
{
inTK = dummy.Length.ToString();
pot = int.Parse(dummy.Length.ToString()) - 1;
inTOKO = dummy.Substring(0, pot);
}
Session["inTOKO"] = inTOKO;
the problem is where in my variable inTOKO consist of couple of value...
Example
while variable inTOKO = one value success but while value inTOKO = two value error
inTOKO = 1101111 => success
inTOKO = 1101111,1211321 => not success

can capture return value from a SQL by using SqlConnection SqlCommand

I'm trying to determine whether it is better to declare the connection outside with it's own using statement or to create it inside the sqlcommand itself. This is in regards to a single command interaction with the database (no loops).

I am accepting query/queries from user (our support team) in a text box where user can enter only one query or multiple queries. I need to display result of all queries entered in the textbox. If it is SELECT statement then result of that statement in grid which is done. If UPDATE/INSERT/DELETE then total number of rows affected which is also done but if only one UPDATE/INSERT/DELETE statement is entered in the textbox.
If user enters 2 UPDATE statements and then a SELECT statement then how can I get number of rows affected for individual UPDATE statements just like SQL Server Qury Analyzer displays messages in its result pane.
e.g.
(6 row(s) affected) -- first UPDATE statement
(4 row(s) affected) -- second UPDATE statement
(16 row(s) affected) -- for SELECT statement (grid will also be displayed along with these messages).
I tried almost everything, SqlDataSource (returns count of first statement only), SqlCommand.ExecuteNonQuery and DataAdapter.Fill (returns count of last statement only).

I have a web page where a GridView will be shown with a column of different products and another column with checkboxes. Checking on the checkboxes will be equivalent to selecting the products. The selected products are saved to an arraylist. Then, the user has to click on a button located on the same page to analyze the selected products. On clicking the button, he/she will be directed to another page where a bar graph will be shown. The bar graph will be the result of having analyzed the products. How do I create the bar graph where the products are taken from the arraylist but I can make use of the datasource within the chart control to retrieve more detailed info(such as product sales) from the database, taking into account the products from the arraylist?

View 6 RepliesI have an arraylist:
Dim downloadsarray As New ArrayList
downloadsarray.Add(iconlink)
downloadsarray.Add(imgpath)
downloadsarray.Add(filesize)
downloadsarray.Add(description)
Which is the datasource of my repeater:
DownloadsRepeater.DataSource = downloadsarray
DownloadsRepeater.DataBind()
how I output the items in the array to the .aspx page. I usually use (when using sqldatareader as datasource):
<%#Container.DataItem("1stcolumnnamestring")%>
<%#Container.DataItem("2ndcolumnnamestring")%>
But this does not work when using the arraylist as datasource.
I have a GridView control of 5 columns out of which 2 are actually computed (there cell values comes from column 1, 2 and 3) columns. I want to save all the values of my gridview columns in a 5 dimension ArrayList and then lateron bind that ArrayList with a repeator control.

I have an arraylist that contains some values. (e.g. playerName). I also queried for values in the database (e.g. playerName, playerSales) and I need to match the playerName in the arraylist to the corresponding ones that I did a query from the database. (match those with the same playerName). From there, I need to create a bar graph with the respective playerName and their sales (playerSales).

I have a gridview, where I have made autocode using the wizard. However I need a dynamic SQLcommand from server side. I have tried this code, but it doesn't work, it works if I use this code from HTML (setting the sqlcommand in the SQLDataSource. I have deleted the sqlcommand from the HTML and instead I have implemented the code in the page_load event:
Code:
Dim str As String = SqlDataSource1.SelectCommand = "SELECT DISTINCT Beregning.bId, Informationer.Dato,Beregning.bType, Informationer.pNavn, Informationer.pNr, Informationer.Beskr, Beregning.uId FROM Beregning CROSS JOIN Informationer WHERE (Beregning.UserId = @UserId) AND Beregning.uId = Informationer.uId AND (Beregning.bType=@berType2) ORDER BY Beregning.bId DESC"
SqlDataSource1.SelectCommand = str But this code works, when I apply the SQLCommand in HTML:
Code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:IsoPlusConnectionStringDrift %>" SelectCommand='SELECT DISTINCT Beregning.bId, Informationer.Dato,Beregning.bType, Informationer.pNavn, Informationer.pNr, Informationer.Beskr, Beregning.uId FROM Beregning CROSS JOIN Informationer WHERE (Beregning.UserId = @UserId) AND Beregning.uId = Informationer.uId AND (Beregning.bType=@berType) ORDER BY Beregning.bId DESC'>

I have another class that creates the connection (see refined class half way down page) and I believe it connects or at lest I do not hit any of the exceptions in run time.
I would now like to insert data into my database but nothing is updated.
I am trying to follow this example but it is for reading.
I did run "querystring" on the show SQL Pane and it does execute correctly. It inserts data properly as a new row.
string queryString =
"INSERT INTO UserData UserProfileID, ConfidenceLevel, LoveLevel, HappinessLevel) VALUES ('a051fc1b-4f51-485b-a07d-0f378528974e', 2, 2, 2);";

{.....
a) SqlCommand.ExecuteNonQuery is used for update, insert and delete operations.
Besides the fact that by using ExecuteNonQuery instead of ExecuteReader we automatically know there won't be any query results returned, are there some other benefits/reasons why ExecuteNonQuery should be used?
b) Similarly, if we want a database operation to return a single value, we should use ExecuteScalar instead of ExecuteNonquery ,where with the latter result would be returned via SqlParameter. Is there any particular reason why we should prefer ExecuteScalar over ExecuteNonQuery?
I have an ArrayList of strings called 'vins'. I have set DataGrid1's data source set to 'vins'. When I check off create columns automatically at runtime the DataGrid is populated with the correct values from the arraylist, however I'm not sure how to reference them. I'm trying to make it so that a user can click on a link after any VIN number and have that referenced and deleted from the arraylist. bind this ArrayList to the DataGrid and then be able to reference them.
