In my application if I get an exception I catch it and send stackTrace through email. I also need the values of parameters passed to this function. I can get the names of function and parameters using MethodBase class of System.Reflection.

I haven't used these in awhile. I was just wondering is it possible to pass values or parameters to a user control from the aspx page. Say you register a control and then use it using something like
<uc1:SampleUserControl id="SampleUserControl1" runat="server"></uc1:SampleUserControl>
style syntax. Can you pass parameters in there?
I want to set ASP.net custom validator error parameter text through client side javascript. How can access it via sender, args parameters in my function?
View 1 RepliesI am very new to Asp.net--I think this should be very straightforward, but it's not working for me. I'm tyring to pass a variable between pages (actually it's from the same page, but same idea) to query a database and fill a grid.
I'm using this line to call the page:
<a href="Webform2.aspx?letter=A">A</a>
and this for the query and grid
<asp:AccessDataSource ID="AccessDataSource1" runat="server" DataFile="database.mdb" SelectCommand="SELECT [Hyperlink], [Type], [Language] FROM [List] WHERE [Alpha]=@letter">
<SelectParameters>
<asp:querystringparameter DefaultValue="B" Name="Alpha" QueryStringField="Alpha" Type="String" />
</SelectParameters>
</asp:AccessDataSource>
I want it to fill the grid with values where [Alpha] = "A" (passed value) but it fills it with values where [Alpha] = "B", my default value.
I'm having trouble figuring this error out. I have a grid on an ASPX page that displays data from a stored procedure in an SQL Server 2008 database. When the page loads, I get the following error:
"Procedure or function <sp_name> has too many arguments specified."
Here is the code for the grid and the datasource:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" ShowFooter="True" OnRowDataBound="GridView1_RowDataBound"
AllowSorting="True">
[code]....
Here's the code from the stored procedure:
ALTER PROCEDURE [dbo].[sp_GatewayMerchants]
-- Add the parameters for the stored procedure here
@StartDate DateTime,
[code].....
The datasource is passing 4 parameters, and the stored procedure is accepting 4, but when the page displays I get the error mentioned above.
EDIT: Here's the code behind for the template column. But I'm not sure how this could be causing extra parameters to the SP.
protected void Command_Click(object sender, EventArgs e)
{
var merchantID = Convert.ToInt32(((LinkButton)sender).CommandArgument);
[code].....
If I remove the ASP:LINKBUTTON the code works. So why would a LINKBUTTON be causing this?
Assuming a static method like below is called from ASP.NET page,can a different thread(b) overwrite the value of s1 after the first line is executed by thread(a)?If so, can assigning parameters to local variables before manipulation solve this?
public static string TestMethod(string s1, string s2, string s3)
{
s1 = s2 + s3;
....
...
return s1;
}
Is there are a simple way to recreate such thread safety related issues?
I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>
I'm using a code-behind function (called TestFx) in my binding expression. I'm passing a string and the function accepts a string but I still get a runtime error saying invalid args.
But if I change the method to accept an object and inspect the value, "it's a string!"
ProductDescription:
<asp:Label ID="ProductDescriptionLabel" runat="server"
Text='<%# TestFx(Eval("ProductDescription")) %>' />
<br />
Below is my aspx
<asp:ObjectDataSource ID="InvitationObject" runat="server" UpdateMethod="EmailUpdate" SelectMethod="ListEmail" TypeName="InvitationDataObject" OnSelecting="InvitationObject_Selecting" > <SelectParameters>
My gridview has hyperlink field which will redirect to another page when clicked. Is there any way to hide the values from being shown in the URL? I do not wish to have encrypted values as well.
http://localhost:3042/Customer/CustomerDetails.aspx?custid=123456
Any way to show it as
http://localhost:3042/Customer/CustomerDetails.aspx only?
I hope this makes sense. I want to pull the largest record from an Access dB if no parameter is passed in a QueryString.
Under normal situations, my query might look like this; http://www.XYZ.com/videos.aspx?id=1
What I would like to do is have the page "http://www.XYZ.com/videos.aspx" load the MAX ID record by default. I tried this, but it won't even load the page portion that is suppose to contain the data and returned no errors;
<asp:AccessDataSource id="AccessDataSource2" runat="server" DataFile="_database/92592_Web.mdb" SelectCommand="SELECT *, (SELECT MAX(ID) FROM myMovies) as Max_IDFROM [myMovies] WHERE ([ID] = ?)" CancelSelectOnNullParameter="False">
<SelectParameters> [code]...

View 3 RepliesI have a SQLDataSource control that is calling a database stored procedure, and passing quite a large number of paramaters, and the stored proc returns records that populates a gridview control. When I walk through the code behind to determine the values being passed, is there any way that I can see exactly how the parameters are being formated and passed to the stored proc?
View 2 Repliesi have passed the values from clientside using querystring. Below link displaying like URL>..i want to encrpyt the following code
?id=vidhansabha&cat_name=Industries&email=rafi045@gmail.com&mobile=9786629228
so I have a web programming assignment for university where I'm building a website that uses an Access database but I have hit a brick wall with something.I'm using parameterized queries to query my database. For one of my queries, I want to be able to take a bunch of parameters that are optional, and if they aren't needed I'll pass in a value of null and I'd like the part of the where clause relevant to them to evaluate to true. This is straightforward in most databases, from my understanding you could do something like to make param1 an optional parameter.
WHERE ((@param1 = ARandomColumnName) OR (@param1 = null))
However this can't be done using Access, as all parameters in a query are represented by a ?. Every ? is assumed to refer to a different parameter, so if you want to use a parameter more than one (like the above code I wrote does) then you'd have to pass it twice. This seems hacky to meSo what do I do? I have spent *hours* googling and banging my head on the desk. I'll cry if I missed something really obvious
I have a page like this In my SQL, I want calculate some value between these days And this is my code;

This is my first foray into jquery. I wrote a function that will wrap four sides and four corners around a div, effectively placing a border around a box. I would like to pass in height, width, and a third parameter to indicate hoe much padding that particular box should get. How can I do this?
<script type="text/javascript" src="/Scripts/jquery-1.4.1.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$(".smallBox").wrap("<div class='sbox-top'>" +
"<div class='sbox-bottom'>" +
"<div class='sbox-left'>" +
"<div class='sbox-right'>" +
"<div class='sbox-tl'>" +
"<div class='sbox-tr'>" +
"<div class='sbox-bl'>" +
"<div class='sbox-br' style='padding:5px 5px;'>" +
"<div style='background-color: #f2f0f1;padding:0 5px;'>" +
"</div></div></div></div></div></div></div></div>");
});
</script>
internal static void GetUserData(int userId, out string userName,
out string userEmail, out string userPassword)

{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@UD_ID", SqlDbType.Int).Value = userId;
cmd.Parameters.Add("@UD_UserName", SqlDbType.NVarChar, 100).Direction = ParameterDirection.Output;
cmd.Parameters.Add("@UD_Password", SqlDbType.NVarChar, 100).Direction = ParameterDirection.Output;
cmd.Parameters.Add("@UD_Email", SqlDbType.NVarChar, 100).Direction = ParameterDirection.Output;
cmd.ExecuteNonQuery();
userName = Convert.ToString(cmd.Parameters["@UD_UserName"].Value);
userEmail = Convert.ToString(cmd.Parameters["@UD_Email"].Value);
userPassword = Convert.ToString(cmd.Parameters["@UD_Password"].Value);
}
}
}
and the call
string userEmail;
string userName;
string userPassword;
MemberHelper.GetUserData(userId, out userName, out userEmail, out userPassword);
Sometimes I need to get just one parameter from the out parameters, how can I call the function when I want to get just one:
string userPassword;
MemberHelper.GetUserData(userId,"","",out userPassword);
I am using 3 web controls ,two are cascading dropdownlists used to filter gridview control bound to a datasource.
My question is , How to define multiple queries in stored procedure that takes parameter values from the controls declared using sqldatasource.Also, return all data when i set default control value to say 'null'.
NB: one paramaterised query for cascading dropdownlists and another for other control.
I'm using AJAX Page Methods, but I can't seem to be able to pass the needed parameters:
function getFavStatus() {
//favs is a list of DOM <imgs> that I want to modify their img.src attribute
for (i = 0; i < favs.length; i++) {
PageMethods.isFavorite(favs[i].alt,setFavImg(favs[i]));
}
}
function setFavImg(fav, response) {
fav.src = response;
}
The problem that I can't figure out is how to use the "response" from PageMethods, AND pass the DOM object to the callback function.
I've also tried doing something like this:
function getFavStatus() {
for (i = 0; i < favs.length; i++) {
PageMethods.isFavorite(favs[i].alt, function (response) {
favs[i].src = response;});
);
}
}
In this case, the response works properly, but i is always > favs.length, because it has already iterated through the loop... Edit: My PageMethods.isFavorite signature is: [System.Web.Services.WebMethod] public static string isFavorite ( string p_id )
i am looking for a function that takes two string parameters
str1 = "hello how are you today mr john"
str2 = "how today"
and in return it shoud highlight the words "how" and "today".
I have an MS SQL function that is called with the following syntax: SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = 7 AND LocationName = ''Default'' ', 10) The first parameter passes a specific WHERE clause that is used by the function for one of the internal queries. When I call this function in the front-end C# page, I need to send parameter values for the individual fields inside of the WHERE clause (in this example, both the ClientID & LocationName fields) The current C# code looks like this:
String SQLText = "SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE
ClientID = @ClientID AND LocationName = @LocationName ',10)";
SqlCommand Cmd = new SqlCommand(SQLText, SqlConnection);
Cmd.Parameters.Add("@ClientID", SqlDbType.Int).Value = 7; // Insert real ClientID
Cmd.Parameters.Add("@LocationName", SqlDbType.NVarChar(20)).Value = "Default";
// Real code uses Location Name from user input
SqlDataReader reader = Cmd.ExecuteReader();
When I do this, I get the following code from SQL profiler:
exec sp_executesql N'SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable
(''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)',
N'@ClientID int,@LocationID nvarchar(20)',
@ClientID=7,@LocationName=N'Default'
When this executes, SQL throws an error that it cannot parse past the first mention of @ClientID stating that the Scalar Variable @ClientID must be defined. If I modify the code to declare the variables first (see below), then I receive an error at the second mention of @ClientID that the variable already exists.
exec sp_executesql N'DECLARE @ClientID int; DECLARE @LocationName nvarchar(20);
SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable
(''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)',
N'@ClientID int,@LocationName nvarchar(20)',
@ClientID=7,@LocationName=N'Default'
I know that this method of adding parameters and calling SQL code from C# works well when I am selecting data from tables, but I am not sure how to embed parameters inside of the ' quote marks for the embedded WHERE clause being passed to the function.
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:
<asp:Literal
ID="CommentFooterLiteral1"
Visible='<%# Eval("Approved") Or IsModerator() %>'
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 need to send som parameters to the callback function of my AJAX call, how can i do that: ex.
