when i worked in .NET 1.1 i used to pass parameters to user control using the method- (if the name of the usercontrol is "tables")
dim r As tables =
CType(Page.LoadControl("~/usercontrol/tables.ascx"), tables)
and calling public property of the usercontrols.
the problem is that i can't the way to do it in 2008 ver of .NET, it is not recognize the usercontrol.... how can i pass parameters to the usercontrol in run time?
in my asp.net mark up I have a foreach loop that iterates through a simple list. In this foreach loop I am adding a new user control and attempting to pass in the value from the loop. However, this value just wont budge and get inside that damn control!
<%foreach (userInfo i in this.items)
{ %>
<uc1:ItemControl ID="ItemControl" runat="server" UserID='<%#Eval("userID") %>'/>
<%} %>
userID is a public property in the control, when it goes to set, the value is just literally :
<%#Eval("userID") %>. I've tried #Bind and =Value but nothing seems to work.
I am new to MVC, and trying something and got stuck somewhere in between.I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like
<input type="button" value="Search"
onclick="location.href='<%= Url.Action("action", "controller") %>'" />
I have called this usercontrol on some view through
<%= Html.Partial("ucName") %>
Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid.I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.
In this answer to my question of how to insert data into SQL Server he mentioned passing parameters instead of string concatenation like I currently have.
Is this really necessary for security? If so, what exactly is passing parameters? When i google it I get a lot about stored procedures. Is that what I want, I do not know about stored procedures....yet.
EDIT:
Ok, here is what I got. It seems to update the database correctly and eventually I will change the hard coded ints to inputs from a label. confirm if how I did this is not vulnerable to any sql injection or hacks.

Command.Parameters["@HL"].Value = 9;
Command.ExecuteNonQuery();
}
}
How do it do this. I have this at the moment

This takes a large INT and returns 4 strings from the BO structure HotelFacilities
If I set the private from string to AccommodationBO.HotelFacilities it is fine
If I set the public from string to AccommodationBO.HotelFacilities it moans because the Set section of the private property is wrong. But the set would be an INt.
All I actually want to do, is populate the BO Structure and passit to the user control using a property in the user control code behind. Is this possible ??

I have a particular scenario and I would like to know how I can implement it in the most efficient way. I also have some queries related to this. The application is a AJAX 1.0-Enabled ASP.NET 2.0 Web application.
I have a link, which when clicked I need to show a pop-up div. The contents of the div will be displayed using a usercontrol. The usercontrol will display the contents based on a query string value.
I would like to know:
1. How can I implement this in the most effecient way. I don't want to use a separate page on which I will have the usercontrol and then display the page in the div.
2. Suppose I call a JS function ShowDiv() on the click of the link, to display the pop-up div. Say, I call the function this way ShowDiv('querystring'). Now how will I pass the value 'querystring' to my usercontrol.
I am trying to use a parameter field where there is a subreport in my main report but i keep getting the error "subreport cannot be shown" when running the report.
p.s - I have just set the parameters the same in the subreport as the main report.
I have a page with a lot of pictures on it. I want the user to be able to click on the picture and either bring up a popup type of window passing it the Param name and value , or to have the picture be replaced with this object.
<object id="ADR2" type="application/x-Autodesk-DWF"
width="250" height="250"> <param name="dwffilename"
value="path" /> </object>
I have found a number of places describing how to bring up a popup window, but not on how to pass it the values.
I have a custom ExpressionBuilder in whixh I'm trying to add a list of optional parameters. My method would be declared as follows:
public static string GetResource(string expression, params object[] parameters) { }
The way I'm calling this method from an ASP.NET page is this at the moment:
<ext:Button ID="btnEdit" runat="server" Text="<%$ AppResources : edit_text %>">
Does anyone know how to perform this method call, but using optional parameters?
I have a simple Web Service method defined as:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string MyWebMethod(string foo, string bar)
{
// DataContractJsonSerializer to deserialize foo and bar to
// their respective FooClass and BarClass objects.
return "{"Message":"Everything is a-ok!"}";
}
I'll call it from the client via:
var myParams = { "foo":{"name":"Bob Smith", "age":50},"bar":{"color":"blue","size":"large","quantity":2} };
$.ajax({
type: 'POST',
url: 'https://mydomain.com/WebServices/TestSvc.asmx/MyWebMethod',
data: JSON.stringify(myParams),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (response, status) {
alert('Yay!');
},
error: function (xhr, err) {
alert('Boo-urns!');
}
});
However, this yields the following error (a breakpoint on the first line in MyWebMethod() is never hit):
{"Message":"No parameterless

I am creating a DataSet to attach to a report (*.rdlc). In the DataSet is a TableAdapter that has the GetData(@start, @end) function. Can someone please explain how I get values in to @start and @end? I have searched and seen that it might have something to do with overriding the Fill function in the DataSet code behind file. Please let me know.

I have a dynamic created drop down list - and I set the event of it to be like this:
ddlAnswer.ID = "ddlistAnswer" + QuestionID;
ddlAnswer.SelectedIndexChanged += new EventHandler(ddlAnswer_SelectedIndexChanged);
Please note that drop down list is dynamic, and in selectedIndexChanged, I would like to pass the "QuestionID" to that selectedindexchanged to work on my logic. Is there a way to pass it to that method as command argument or something?
Code:
protected void ddlAnswer_SelectedIndexChanged(object sender, EventArgs e)
{
//wanting that question id here
}
STR= "SELCT * from tbl1 ";
if (drpyrsal.SelectedValue != "--Select--")
{
STR= STR+ " and Year([frmdt])=" + drpyrsal.SelectedValue + " ";
}
if (drpmonth.SelectedValue != "--Select--")
{
STR= STR+ "and Month([frmdt])=" + drpmonth.SelectedValue + " ";
}
and execute it with dataset
how can i do the same with SP
SqlCommand cmd = new SqlCommand("usp_SP1", con); // Stored procedure
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@yr", drpyrsal.SelectedValue);
cmd.Parameters.AddWithValue("@mon", drpmonth.SelectedValue);
passing parameters from a datalist to another page.
this is how my app works:
i have a database ( access) a table with the following columns: id,title,desc,photo.
another table with the following columns: (startsin, endsin,price,tId)
on the first page (tourpack.aspx) i have a datalist, when user clicks on a button that is in the templateitem of the datalist, he will be transfered to another page called (showtour.aspx). what im trying to do is passing the ID parameter from the first page (table 1) to the second page (showtour.aspx) with the id number so he can see the specific details of that "tour" that are located In the second table.
Im wonding what the correct syntax is to pass 2 parameters from a Ascx control into a Vb.net function? Heres what I currently have:

Text='<%# FormatFooter(Eval("Anonymous"), Eval("DisplayName"), Eval("CreatedDate")) + "
" + GetModeratorStatus(Eval("UserId")) %>'
runat="server"
/>
The Function "FormatFooter", needs to pass in Anonymous and DisplayName parameters. Anyone know the correct syntax for doing this?

I'm trying to do a form submit to my controller through jQuery Ajax. The following code works for the most part, however, the ThreadId parameter does not get passed. If I call the controller directly without using jQuery, it gets passed, but when using jquery, I don't see the ThreadId after form.serialize(). WHat would be the easiest way to pass parameters (like ThreadId) to jQuery form post?
