C# - Cannot Pass A Input From Text Box To A Query String And Then Keep The String In This Box?
May 28, 2010I have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?
MVC :: Query String Parameters And View Model Fields?
Feb 15, 2010i just noticed that if my controller has a parameter with a name that matches the name of a field in my view model, and the view emits the value of the model's field, the value emitted is that passed in the query string, not the one set by the controller. is this by design?
here is what i mean:
my view model:
public class MyViewModel
{
int id;
string name; [code]....
sending a request to "create?id=1234" emits "1234" in the hidden field instead of "1".

How To Set Value To Html Hidden Fields
May 23, 2010I have scenario, where there are html hidden fields, the page can be redirected to itself, with parameters, I have sessions too. Now depending on session value I want to set some hidden values, so that it can be picked up from javascript and can do certain operation. But, the problem is I have no idea about how to get/ set values into html controls using asp.net, and also do not know whether this is possible or not. it is imperative that I need some way to hold some data that can be set using asp.net and can be picked up by javascript. Since session can not be used for this purpose, so I need some other way.
View 2 RepliesSet Parameter Value Without Using Hidden Fields?
Jul 6, 2010I've been using .NET for a little while now. And, I now want to learn to use it the RIGHT way. And, by that, I mean I shouldn't be using hiddenfields on my .aspx page and setting values for those hidden fields in my codebehind. Problem is, I don't know how to ask the question.. so bare with me.. getting a value from a gridview, detailsview, or in this case a DataList when it's bound on a .aspx page, and passing it into my stored procedure? Here's my code of how I do it now..
here's the label for the Department from my datalist, which is on my .aspx page
<asp:Label ID="lblFullDept" runat="server" Text='<%# Eval("FullDept") %>' />
here's the hidden field from my .aspx page
<asp:HiddenField ID="hdnFullDept" runat="server" />
And now for my code behind - where I find the value during the databound of the datalist, and then set the value equal to the hidden field.
Protected Sub dlInfo_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dlMnfo.ItemDataBound
Dim lblFullDeptCompare As Label = CType(e.Item.FindControl("lblFullDept"), Label)
hdnFullDept.Value = lblFullDeptCompare.Text
End Sub
And finally, the sql portion, where the value is passed as a parameter...
Protected Sub doInsertActivation()
Dim conn As SqlConnection
Dim comm As SqlCommand
Dim reader As SqlDataReader
Dim connectionString As String = ConfigurationManager.ConnectionStrings("xyz").ConnectionString
conn = New SqlConnection(connectionString)
comm = New SqlCommand()
comm.Connection = conn
comm.CommandType = Data.CommandType.StoredProcedure
comm.CommandText = "abc123"
comm.Parameters.AddWithValue("Department", hdnFullDept.Value)
conn.Open()
reader = comm.ExecuteReader()
reader.Close()
conn.Close()
End Sub
Yes, this works, but I just feel like I need to learn a more efficient way of doing this, as I'm constantly grabbing data and inserting it into sql.
