I have big filter coming from database by using storedprocedure. This stored procedure contains about 12 parameters. In asp.net page I select these values and after doing that I want to pass these values to SqlDataSourec which is bound to gridview. How can I pass these values to SqlDataSource, manually in codebehind?

I am trying to add a hyperlink to the below listview. This hyperlink passes multiple parameters to the next page? I am trying to achieve the below, works with a gridview but not below.
View 4 RepliesI try to pass two parameters to code behind
Into gridview
Visible='<%# Show(DataBinder.Eval(Container, "DataItem.Id").ToString()) %> + <%# MostrarBotonBorrar(DataBinder.Eval(Container, "DataItem.Rol").ToString()) %>'
in codeBehind:
public bool Show(string value,string value2)
{
if(value == LbluserInvisible.Text)
{
return true;
}
else
{
return false;
}
}
I am creating a grid with a code behind and in the hyper link column I would like to pass some parameters before passing users to a new page. If I just use one parameter, the CustomerID in the dataNavigateUrlFields and dataTextField then the
linkField.DataNavigateUrlFormatString = @"/details.aspx?Customerid={0}";
statment works fine.
Now my requirement is to pass multiple parameters and when I tried the following it gave a
'A field or property with the name 'System.String[]' was not found on the selected data source.'
Here is the code snippet:
HyperLinkField linkField = new HyperLinkField();
string[] dataNavigateUrlFields = { "CustomerID", "CompanyName", "FirstName" };
linkField.DataNavigateUrlFields = dataNavigateUrlFields;
string[] dataTextField = { "CustomerID", "CompanyName", "FirstName" };
linkField.DataTextField = dataTextField.ToString();
linkField.DataTextField = "CustomerID";
linkField.HeaderText = "Customer ID";
linkField.DataNavigateUrlFormatString = @"/details.aspx?Customerid={0}&CompanyName={1}&FirstName={2}";
Does some one know how pass the multiple parameters via the hyperlinkfield in C#?
I need to pass parameters via a gridRowView to a button I have a gridView that currently allows row selection via a radio button What I need to do is based on that selection is pass the parameters to one of 4 button options within the footer. This will then open a new page based on those values. I'd got this working using a hyperLinkButton and querystring but now I'm really struggling with the new requirement "it must be a button" selected this way
Here's my code, if it helps anyone to see it?
<asp:GridView
ID="gvSavedChanges"
runat="server"
AllowPaging="True"
AllowSorting="True"
AutoGenerateColumns="False"
CellPadding="4"

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?

I have ASPxDataView and ASPxRadioButtonList within item template. i also have two SQLDataSource's (first fill ASPxDataView, second ASPxRadioButtonList). They are using other database tables connected with the foreign key. Is there any way to pass parameter to my second sqlDataSource (id) to fill RadioButtonList property ? i mean select * from TABLE2 where id = @id ; (@id is a value from TABLE1 which is a value of column returned by first sqlDataSource)
View 3 RepliesI have asked similiar question before where I have two control on the page header says "username" and "gender". User can select both the control or either one and the page will execute searching based on the criteria supplied. So if username supplied
SELECT * FROM [this_table] WHERE username = @username
and if gender supplied
SELECT * FROM [this_table] WHERE gender = @gender
and if both supplied
SELECT * FROM [this_table] WHERE username = @username AND gender = @gender
I know this sounds not very complicated but in my case, I am having like more than 10 controls up there. It is something likeusername, gender, age, date of brith, title, father name, frst name, last name, blur blur blur and it's a lot then I started to lost. if i were to use if else caluse on code-behind and produce query, it would end up writing a lot of if-else and if i use stored procedure (with if-else) then my stored procedure would contains a lot of if-else statement. I am fairly new to this concept and if I'm on the wrong track, please correct me. Is there any better way to save my hair without actually going through each
if-else statement to build the query ?p.s. I'm using GridView and SqlDataSource command to display the result back on .aspx page.
I am trying to check whether a username exists in my database before inserting the new row & display a message to the user if it does.
On my SqlDataSource my InsertCommand looks like this:
InsertCommand="IF NOT EXISTS (SELECT * FROM Users WHERE UserName = @UserName) BEGIN INSERT [Users] ([UserName], [FirstName], [LastName], [City], [State], [Country], [CompanyName], [Active], [PasswordHash]) VALUES (@UserName, @FirstName, @LastName, @City,
@State, @Country, @CompanyName, @Active, @PasswordHash) END"
This works as expected: If the username is unique, the row is created.
If the username already exists, the row is not added.
The problem is, if the row already exists, the insert is rejected but the user is not notified.
So my question is, is there a way I can notify the user?
Maybe something like: InsertCommand = "If Not Exists (select....) Begin Insert...Else Notify User Somehow End This is a basic database, I'm not using the built-in membership provider nor will be.
In one of the web page say "Default1.aspx" I have a Gridview.I am using 2 DataKeyNames in Gridview. i.e., DataKeyNames="G_Name, Param_ID" Also, I have one Hyperlink inside Gridview, upon clicking, page navigates to other page say "Default2.aspx"
code of "Default1" page:
<asp:GridView ID="GridView1" runat="server" DataKeyNames="G_Name, Param_ID" AutoGenerateColumns="False" Width="100%" PageSize="8" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging">
<Columns>
<asp:BoundField HeaderText="Goal Name" DataField="G_Name" Visible="false"/>
[Code]....
code of "Default2" page:
protected void Page_Load(object sender, EventArgs e) {
if (!Page.IsPostBack) {
string name = Request.QueryString[0].ToString();
string id = Request.QueryString[1].ToString();
}
}
I want to pass multiple parameters in querystring. I wrote above code.
Problem is: I am unable to write the correct syntax for Hyperlink NavigationUrlTherefore, it is giving me below error:
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'GF_Name, Param_ID'.
at Line:
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("GF_Name, Param_ID","~/Default2.aspx?Name={0}&Id={1}") %>'
Text='<%# Eval("GF_Name") %>'></asp:HyperLink>
how to resolve it.

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?
if i do this to set the fetch parameters:
dsList.SelectParameters["client_id"].DefaultValue = Session["client_id"].ToString();

dsList.InsertParameters["client_id"].DefaultValue ="1234";
it keeps saying its null, i dont understand why it woudl be doing this?

a FormView that is linked to SqlDataSource1a Repeater control (inside the formview) that is linked to SqlDataSource2Thus representing a simple "1 to many" or "parent/child" relationship in the database!qlDataSource1 is simple in that it just retrieves a straight set of records from a table and they are displayed back in the FormView (nothing special happening there).SqlDataSource2 has parameters that filter the contents of the repeater based on the record that is shown in the Formview. This would normally be simple enough to set up by setting the parameter to the formview.selectedvalue property.HOWEVER - THE PROBLEM ARISES...The formview has multiple DataKeyNames because the table that the SqlDataSource1 links to has a compound key. So to filter the Repeater correctlySqlDataSource2 needs to map 3 parameters to 3 data key values in the formview.Any ideas how to do this?I've tried setting the SqlDataSource2 parameters to:
<SelectParameters>
<asp:ControlParameter ControlID="FormView1" Name="Parameter1" PropertyName="DataKey(0)" />
<asp:ControlParameter ControlID="FormView1" Name="Parameter2" PropertyName="DataKey(1)" />

I am trying to pass the parameters dynamically thru Sqldatasource and get the results in grid view. Based on the dropdown list selection it has to show the results in grid view. When I hard code its giving correct results but when passing thru parameters i'm unable to get the results in grid view.
Output shud be something like this:
Select the value: 123
124
125.
Lets say user selects '123', the query it runs in sqldatasource is Select col1,col2,col3 from table1 where col1 LIKE '123%'
results will be 12301,12302,12303 with other columns in grid view.
