So Basically I want Filter Data With Clickable query Strings Parameter Values
Problem : How can i Make Url Like this and it is Dynamic
I'm having troubles passing a parameter to a handler in it's query string. I have a gridview with an image column, this column is defined as a TemplateField, as:
As you can see, the ImageUrl is a call to a handler that receives the EmployeeID in the QueryString, under the name ID. When I run it, the ImageHandler method receives the following query string "ID=<%" instead of "ID=<the result of Eval("EmployeeID")>", and of course, it throws a FormatException when using it as an int to get the EmployeeID. (If I type ImageUrl="~/ImageHandler.ashx?ID=<%# Eval("EmployeeID")%>" (using " instead of ') the compiler returns the error incorrect server tag) The complete markup is:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" SelectCommand="SELECT [EmployeeID], [LastName], [FirstName], [Photo] FROM [Employees]"> </asp:SqlDataSource> <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="False"> <Columns> <asp:BoundField DataField="EmployeeID" HeaderText="ID" SortExpression="EmployeeID" /> <asp:BoundField DataField="FirstName" HeaderText="FirstName" SortExpression="FirstName" /> <asp:BoundField DataField="LastName" HeaderText="LastName" SortExpression="LastName" /> <asp:TemplateField HeaderText="Image"> <ItemTemplate> <asp:Image ID="Image1" runat="server" ImageUrl='~/ImageHandler.ashx?ID=<%# Eval("EmployeeID")%>' /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> Could anybody tell me what am I missing here?

I have a page that is used to add info from a gridview into a user's profile. I have explained my issues after all of the code. Here is the applicable code(s) involved:
Protected Sub AddToCart(ByVal sender As Object, ByVal e As CommandEventArgs) For Each gvr In GridViewItems.Rows Dim txtGiftAmt As TextBox = (CType(gvr.FindControl("txtGiftAmt"), TextBox)) If txtGiftAmt.Visible = True Then Dim customPrice As String = txtGiftAmt.Text.ToString 'HERE is where I would like to set the new price variable value somehow End If Next Dim scart As New ShoppingCart scart.AddCartItem(e.CommandArgument.ToString()) Response.Redirect("~/ShoppingCart.aspx") End Sub
This sub is called by the following button when clicked:
[Code]....
Here is the sub from the ShoppongCart Class named AddCartItem:
[Code]....
Here is the problem that I am having: I have one specific item that allows user's to define their own price (for this item only). By putting this price in a session variable seems to be the easiest way to handle this (at least for me), but the session variable's value always "lags behind". By this I mean that the first time the items is entered, it uses the default value of cartItem.ItemPrice. The second time the same item is added (with the intention of a different price), this new item's cartItem.ItemPrice is set as the first session("customPrice").
Because the user is selecting his/her own price for this item, I am not worried about lack of security involved with using query string to pass this price, but I can't get the string passed to the ShoppingCart class correctly (shows up null). Is there a way to append this customPrice to the current page's query string before the Response.Redirect takes place? If I understand this correctly, the Response portion "posts back" to the current page before the Redirect sends us on our merry way, right?
my c# web application populating dropdowns with datas at run time... i.e my web form contains 3 dropdowns and one gridview.. dropdown1 populate with 'pgmtitle' which is fetch from database,when user select one item-pgmtitle from dropdown1,participants(BadgeNo,Name) of that pgm will be populated in gridview. when user click on the participant badgeno,dropdownlist3 will poputated with recieving officers name.. wen user select one of the recieving officer from dropdown3,his designation is dispalyed in a textbox,and dropdon2 will populated with feedback sentdate... this is my requirement... and my pblm is, when i choose another pgmtilte(say pgmtilte2) from dropdownlist1,previous value associated with(pgmtilte1) appended with dropdown2 and dropdown3.. here is my HTML code:-
how to pass through a query string parameter of an assignment id and then checking and validating this as a number and displaying the information returned on screen. At present I have code which displays the information on screen but this is by entering in the assignment id and by triggering the button click event, I've shown the code for this below:
.aspx <div> <b>Current Assignment</b> <br /> <asp:TextBox runat="server" ID="txtAssignmentID"></asp:TextBox> <asp:Button runat="server" Text="Get Assignment" /> <br /> <b>Date Started:</b> <asp:Label runat="server" ID="lblAssignmentStart"></asp:Label> <br /> <b>Status:</b> <asp:Label runat="server"></asp:Label> <br /> <b>Current Achievement Level:</b> <asp:Label runat="server" ID="lblAssignmentLevel"></asp:Label> <br /> <b>Date Last Calculated:</b> <asp:Label runat="server" ID="lblAssignmentCalcDate"></asp:Label> <br /> </div> .cs protected void cmdGetAssignment_Click(object sender, EventArgs e) { //Check the assignmentID is an integer int AssignmentID = 0; try { AssignmentID = TypeConv.CInt(txtAssignmentID.Text); } catch { } if (AssignmenttID > 0) { //Create new TCAAssignment object by passing the ID TCA Assignment Current Assignment = abc.TCA Assignment (AssignmentID); lblAssignmentStart.Text = Current Assignment.dDateCreated.ToString(); lblAssignmentStatus.Text = CurrentAssignment.rTCAAssignmentStatus.dDescription; if (!CurrentAssignment.dTCAAchievementLevel.IsNull) { lblAssignmentLevel.Text = CurrentAssignment.rTCAAchievementLevel.dDescription; } lblAssignmentCalcDate.Text = CurrentAssignment.dAchievementDate.ToString(); } }
Code example passing through a query string parameter of an assignment id would be great.
I have a dropdown list that won't populate data values from database using sql datasource. When i use the code behind, i was able to populate the data to the dropdown list. I dont know how to pass the Query String Parameter using code behind since i am new in asp.net. This is the code behind:
Imports System.Data.SqlClient Partial Class PhotoAlbum Inherits System.Web.UI.Page Dim oConn As New SqlConnection("Data Source=.SQLEXPRESS;" & _ "AttachDbFilename=|DataDirectory|ASPNETDB.MDF;" & _ "Integrated Security=True;User Instance=True") Dim oCmd As New SqlCommand() Dim oDR As SqlDataReader Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load oConn.Open() oCmd.CommandText = "SELECT [CategoryID], [Name] FROM Categories ORDER BY [Name]" oCmd.Connection = oConn oDR = oCmd.ExecuteReader() Me.categories.DataSource = oDR Me.categories.DataTextField = "Name" Me.categories.DataValueField = "CategoryID" Me.categories.DataBind() oDR.Close() oConn.Close() End Sub End Class
I will like to include the following information from sqlDatasource to the codebehind:
SelectCommand="SELECT [CategoryID], [Name] FROM [Categories] WHERE ([UserId] = @UserId) ORDER BY [Name]"> <SelectParameters> <asp:QueryStringParameter Name="UserId" QueryStringField="ID"/>
As you can see from the code behind, i was able to add :
"SELECT [CategoryID], [Name] FROM Categories ORDER BY [Name]".
But i will like to add all of this:
SelectCommand="SELECT [CategoryID], [Name] FROM [Categories] WHERE ([UserId] = @UserId) ORDER BY [Name]"> <SelectParameters>
I have a stored procedure that is close to working. It takes the values of a details view puts them into the respective table 'entity' then should also put the @@identity into 'entloan' and should put the LoanID which is in the query string of the page the detials view is loaded on, into the LoanID field of entLoan as well. Everything works except for getting the querystring value to pass to a insert variable on my stored procedure.
Stored Procedure
[Code]....
I do not have a LoanID Insert parameter set as it is not in entity table:

I have been playing around with different code in the backend but always get errors:
i have a function which returns a value from a query string parameter, i use it in more than 10 places in the webapp thus i have to rewrite the code every time, again and again.so to make it short, is there any way i can embed the code somewhere and keep referring to it through out my app?
We are using a asp.net page to submit data to server. what we do is we will pass as parameter in url Query string) and in page load we take that values and submitting to database I have these following doubt
1, What is the default event happening while we call a ASP.NET page is it a POST or GET? We tried to call this url from a mobile application, it is not happening , we are not getting any error also in the mobile application.
2, IF we are calling the url to submit data from mobile applications which one we have to use (GET or POST)
3, IF we are calling this url from an application running in PC to submit which one we have to use ?
Is it possible to attach the Username as a query string with the DestinationPageUrl or reference the value in the code behind. I've tried lgnExcel.UserName.ToString()
In the original site, master page has code-behind to check a query string parameter value. Depending on this value, code-behind dynamically modify some CSS property to hide / display master page elements.
As MVC2 has no code-behind because we are supposed to perform everything in the controllers, how should I proceed in this case ?
I see this : [URL]
It partially answers my needs but the query string processing is common to all pages. How can I move this processing in a common code section ?
I've a page in ASP.NET, whose appearance can change based upon a given parameter(say query string),
How can I achieve this in ASP.NET, Master pages concept won't work here, as even the contents of the page and positioning of the controls on the page can change based upon the parameter.
One solution I can think of is using XSLT, but is there any other solution I can use to solve this problem? Is there any concept of templates I can use here?
I am trying to set up a page that has two behaviors. I'm seperating them by URL: One behavior is accessed via /some-controller/some-action, the other is via /some-controller/some-action?customize. It doesn't look like the Request.QueryString object contains anything, though, when I visit the second URL...I mean, the keys collection has one element in it, but it's null, not 'customize'. Anyone have any ideas about this or how to enable this. I'd like to avoid manually parsing the query string at all costs :).
I have a SQL query I'm running in an ASP.NET page. The final parsed SQL needs to contain a list of string values in the WHERE [columnname] IN [values] format. For example, the final query might look something like this:
SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN ('ABC','DEF','GHI','JKL', /* etc */);
However, the string values in the WHERE clause need to be dynamic. Normally I use parametrized queries to make my code convenient and safe, so conceptually I'd like to do something like this:
String[] productCodes = { "ABC", "DEF", "GHI", "JKL" }; SqlCommand cmd = "SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN (@ProductCodes)"; cmd.Parameters.Add("@ProductCodes", productCodes);
However, this sort of functionality doesn't appear to exist in .NET. How should I go about implementing this? I could use a foreach loop on the array and run a query with a single value as a parameter for each value, but there could potentially be a hundred or so different values in the array and it seems like querying them separately would be very inefficient.
I've read another question where someone suggested a solution for strongly-typed int parameters, but that method would make me nervous about SQL injection when used with String values, especially since the client may very well be able to influence the input values.
i dont understand where is the problem with my code. i need to pass the request_id to another page but it is always passing the integer values as 0. whenever it comes to pass integer values it is passing it as 0 even if i perform conversion of string to int.
I'm using parameterized sql query to get data from database
string query = "Select * from employee where employee_city in (@value)";
strign city ="'NewDelhi','Bangalore','Mumbai'";
I'm using following code to achive this
[code]...
But this is not giving the result. If run the query in SQLServer query window as "Select * from employee where employee_city in ('NewDelhi','Bangalore','Mumbai')", records are there.
But the same query will not return any records from ADO.Net.
