Hello,
I'm new with ASP.NET and I need to create dynamic buttons.
<script runat="server">
Sub submit(Source As Object, e As EventArgs)
button2.Visible = True
lbl1.Visible = True
button3.Visible = True
End Sub
</script>
<script runat="server">
Sub submit1(Source As Object, e As EventArgs)
lbl1.Text += 1
End Sub
</script>
<script runat="server">
Sub submit2(Source As Object, e As EventArgs)
button2.Visible = False
lbl1.Visible = False
button3.Visible = False
End Sub
</script>
<html>
<body style="height: 184px">
<form id="Form1" runat="server">
<asp:Button id="button1" Text="ADD" runat="server" OnClick="submit" />
<p>
<asp:Button id="button2" Text="COUNT" runat="server" visible="false" OnClick="submit1" />
</p>
<p>
<asp:Label id="lbl1" Text=0 runat="server" Visible=false />
<asp:Button id="button3" Text="REMOVE" runat="server" visible="false" OnClick="submit2" />
</p>
</form>
</body>
</html>
I made this code but it's not really a dynamic, because it uses visible true/false commands.
Can any one help me to make them dynamic.
Thank you.

The term dynamic button means that instead of using an object in the webform, you create the object in code, in the code behind page.
in vb
Dim txt_FirstName_Field As Textbox
txt_FirstName_Field = new TextBox
With txt_FirstName_Field
.ID = "txtFirstName"
.Text = "SomeValue"
End With
controls.Add( txt_FirstName_Field );
I don't remember the last line for code behind pages

i am creating an application, in which i am providing user to download a file only if he is login. if he is logined in then he will be redirect to login page first once login again he will be back to that download page. this is done. but the problem is when i directly going to login page then it doesn't work it goes to null reference please help me to solve this problem. tnx in advance

How are you sending the user back to the original page after he logs in. perhaps you are setting some page url in session or query string.
If yes then, perhaps when user lands on login page directly this value is null. SO you need to check if this value is null and perhaps push the user to the home page.

i am storing page url in a session as it was previously visited and then send to that page, when it is reffer from that download page it works perfectly but when it is going directly to the login page it gives error of null ref to that session
|
|
|
|

Session["url1"] = url;
string s = Request.QueryString["page"].ToString();
if (Request.QueryString["page"].ToString() == null)
{
Session["s"] = Convert.ToString(0);
}
else
{
Session["s"] = Convert.ToString(1);
}
}
if (b == true && Session["s"] == Convert.ToString(1))
{
Session["logintrue"] = "logintrue";
Session["member_name1"] = member_nm;
Session["member_email1"] = member_eml;
Session["member_id1"] = member_id;
string s = Request.QueryString["page"].ToString();
Response.Redirect(s);
}
else if (b == true && Session["s"] == Convert.ToString(0))
{
Session["logintrue"] = "logintrue";
Request.QueryString["page"].ToString();
Response.Redirect("~/member.aspx");
}
else
{
lbl_error.Text = "Invalid email or password";
}
condition is somthing like this... it lands to link stored in "s" which is the download page link, but it doesn't work when user directly lands to login.aspx

You have to capture the previous url, and write it to a temp location before on or before Page.Load. You may want to consider url encoding the url before storage, and url decoding before sending them back to where they came from.
Make sure you capture the complete url including querystrings.
So write the capture, and make a textbox to store it in, then check the value. Then write the redirect, and the url in the browser url bar for accuracy.

Hi, As i think you are using query string to redirect to the login page when user is not login. By doing so you are using Response.QueryString() in your login.aspx.vb or .c# page which results null reference error when opening directly. So checking of querystring exist or not is must here.
As Shown:
If Not IsNothing(Request.QueryString("id").ToString) Then
Dim id As String = Request.QueryString("Id")
End
Great day ahead!

You will probably find more information in the twitter forums[^].
Binding 100,000 items to a list box can be just silly regardless of what pattern you are following. Jeremy Likness

Hi All,
I have an app and it retrieves images from database (image column) and shows the user in a spesific format. However, I use a generic handler(.ashx file) to show the images, it does not show more than 1 image. It only shows 1 image the other images appear like they don't exist. My code is like below;
In aspx page: It prints
In ashx page: I get the byte[] of the images and I write context.Response.BinaryWrite(buffer);
context.Response.Flush();
What can I do? Thx.

Hi, hoping someone can give me hint to solve this. I have a multiview web control in a aspx page with in master page. each view with in multiview has ascx page. by default first index of the view is set to active. as the page needs to go though the standard page life cycle so it will run all page load events of ascx even though i sent the first view to be active view. in one of the ascx page with in the view has a repeater control and i am loading a data in page load event in that ascx and its being executed everytime even though this control is not with in active view.
so in aspx active view index change i added a dataload function for this page so when this the control is in the activeview the data source get bind to the control. these all is working fine. my problem is how do i get the updated dataset from ascx to aspx so i could store it in session or something without adding any function in page load event of user control. please help

In the ascx control you can have a public property that can return a dataset, if the databind is called already and null if it is not called. from the page you can directly use this property to get the dataset out of the control.

but repeater control has drop down list, textbox and are editable and I need to get the value of them as well. how do I do that?
here is a details of my issue
ViewState is disabled through out the entire aspx page
Page contains a multiview control which has views and views has user controls
prev and next button
clicking prev or next button saves current data (SET()) within user control and loads data(GET()) of next user control (if it has any)
one of the user control in a view has editable repeater control. in page load of this control I am binding the repeater as
Repeater.DataSource = List of object
Repeater.Databind()
The problem is, this page load is being called disregard the view being active or inactive.
So I need to bind the repeater else where in the user control
so in my GET() function in aspx (where I load the user control with repeater) I bind the repeater by declaring repeater object as property in ascx as
Me.RepeaterAsProperty.DataSource = List of object
Me.RepeaterAsProperty.DataBind()
I removed databind codes from ascx. upto now it works all good.
When I click next button when this user control is active, I need to save modified data with in this repeater. so in SET() function
I run a loop to get Me.RepeaterAsProperty.Items which is empty. I dont know how to get this working.

Here is my jquery code.
if ($("#ddlRptType").val() == "Monthly") {
var url = "reportPage.aspx?rpttype=" + $("#ddlRptType").val() + "&mm=" + $("#ddlMonths").val() + "&yy=" + $("#ddlYear").val();
window.open(url);
}
else if ($("#ddlRptType").val() == "Daily") {
var url = "reportPage.aspx?rpttype=" + $("#ddlRptType").val() + "&date=" + $('#dailyDatePickerBox').val();
window.open(url);
}
Here is my server-side processing upon page load:
string rpttype = Request.QueryString["rpttype"];
switch (rpttype)
{
case "Monthly":
string mm;
string yyyy;
mm = Request.QueryString["mm"];
yyyy = Request.QueryString["yy"];
GetMonthlyData(rpttype, mm, yyyy);
break;
case "Daily":
string stringdate;
stringdate = Request.QueryString["date"];
GetDailyData(stringdate, rpttype);
break;
}
I have a dropdownlist where I could choose between, daily, weekly and monthly. I verified that the query string is being passed from my jquery code to my receiving page, but sadly it won't proceed to my GetDailyData method. But when I choose Monthly, it works just fine. I put a break point at line:
stringdate = Request.QueryString["date"];
but I can't see its value. I've been trying to debug this for 2 days but I can't figure it out. Thank you guys!
