Hi All,
I'm using ajax modal popup in my application. Following are the steps which I wrote to call modalpopup
1. Add User Control as an modal pop up (DeletePopUp.ascx)
2. In aspx page calling ajax extender (Support.aspx) through panel
2.a) In side Panel1 calling user control
<asp:panel id="Panel1" runat="server" cssclass="modalBox" xmlns:asp="#unknown">
<asp:updatepanel id="updPerson" runat="server" childrenastriggers="false" updatemode="Conditional">
<contenttemplate>
<asp:button id="btnCancelPerson" runat="server" causesvalidation="false" text="X">
CssClass="FlowRight" BackColor="Transparent" />
<uc:deletepop id="DeletePop" runat="server" xmlns:uc="#unknown">
2 b) Calling Ajax modal pop up in same page
<ajaxtoolkit:modalpopupextender id="ModalPopupExtender1" runat="server" xmlns:ajaxtoolkit="#unknown">
TargetControlID="changePwdTitle" PopupControlID="Panel1" BackgroundCssClass="modalBackground"
Drag="true" OnCancelScript="Cancel()" CancelControlID="btnCancelPerson"/>
3. Css class (Corporation.css)
.modalBackground {
background-color: Gray;
filter: alpha(opacity=50);
opacity: 0.5;
}
.modalBox
{
background-color : #f5f5f5;
border-width: 3px;
border-style: solid;
border-color: Blue;
padding: 3px;
width: 250px;
}
It's working fine in Mozilla browser but not supporting IE(any version). In IE Popup come on top and the parent page content go down. It breaks whole page.
I'm using .net 2008 and css2.1.
Please help me to come up from this solution.
Waiting for positive reply....it's very urgent
Thanks in advance

Hi, you must input a trigger code in your update panel.
<trigger>
<asy.... controlid="button1">
</trigger>
Thanks

Hi, I think change your tr to table tag inside of your updatepanel
<td>
<asp:updatepanel id="UpdatePanel1" runat="server">
<contenttemplate>
<table>
<tr>
<td class="style2">
select any one</td>
<td>
<asp:dropdownlist id="DropDownList1" runat="server" autopostback="True">
<asp:listitem>a</asp:listitem>
<asp:listitem>b</asp:listitem>
<asp:listitem>c</asp:listitem>
</asp:dropdownlist>
</td>
</tr>
<tr>
<td class="style2">
your select is</td>
<td>
<asp:label id="Label1" runat="server" text="Label"></asp:label>
</td>
</tr>
</table>
</contenttemplate>
</asp:updatepanel>
</td>
Hope this one can help
Thanks

Hi,
I have a datalist with a button in it. I want to display this button when Advance user logins and make the button invisible when simple user logins. So I want to make the button in the Datalist invisible dynamically. Please tell me how I can acess a button in a datalist to my code. Please reply me if you know any solution to solve this.
Thanks in advance.

for(int i=0;i<datalist1.items.count;i++)>
DataList1.Items[i].FindControl("Button1").Visible = false;
Hope this wil do...

u can write the code inside datalist_Itemcreated event
if session(USerNAme) = "super" then
DataList1.Items[i].FindControl("Button1").Visible = true;
else
DataList1.Items[i].FindControl("Button1").Visible = false;
endif
hope this code will work....

I have two user controls. The first user control starts a table with one row with 3 columns and starts a second row and starts the second cell. The second user control ends what the first control started.
I place the first user control on a page, then I add say a list box and finally add the second user control. The outcome of this is the Top, bottom and sides of the table are predefined in the user controls.
Now my problem... The listbox is not visible. I think it is hidden behind the user control.
When I View Source the tables appear to be correct. Does anyone have any ideas why the listbox does not appear?
Here is the code:
Top User Control "PanelTop1"
<%@ Control Language="VB" AutoEventWireup="false" CodeFile="PanelTop.ascx.vb" Inherits="UserControls_Panels_PanelTop" %>
<table cellpadding="0" cellspacing="0" width="100%">
<tr>
<td class="PanelTopLeft" width="14px">
<asp:Image ID="Image1" Height="1px" Width="14px" runat="server" />
</td>
<td class="PanelTopFill" width="100%">
</td>
<td class="PanelTopClose" width="41px">
<asp:Image ID="Image3" Height="1px" Width="41px" runat="server" />
</td>
<td class="PanelTopRight" width="23px">
<asp:Image ID="Image2" Height="1px" Width="23px" runat="server" />
</td>
</tr>
<tr>
<td class="PanelLeftFill">
</td>
<td colspan="2" >
Bottom User Control "PanelBottom1"
<%@ Control Language="VB" AutoEventWireup="false" CodeFile="PanelBottom.ascx.vb"
Inherits="UserControls_Panels_PanelBottom" %>
</td>
<td class="PanelRightFill">
</td>
</tr>
<tr>
<td class="PanelBottomLeft">
</td>
<td colspan="2" class="PanelBottomFill">
</td>
<td class="PanelBottomRight">
</td>
</tr>
</table>
Page Usage:
<table cellpadding="0" cellspacing="0" width="100%">
<tr>
<td colspan="3">
<uc2:PanelTop ID="PanelTop1" runat="server" />
<table class="PanelTable">
<tr>
<td>
<asp:ListBox ID="ListBox22" Visible="true" AutoPostBack="true" Rows="20" Width="100%"
runat="server" BackColor="#FF0066"></asp:ListBox>
</td>
</tr>
</table>
<uc3:PanelBottom ID="PanelBottom1" runat="server" />
</td>
</tr>
<tr>
<td>
</td>
</tr>
</table>

I want to say I found the problem but the truth is I removed the table around the list box and it worked!
I replaced the table and it still worked! I don't know what the problem was but it is fixed now.

Hey folks,
I need to build an application that does some local file manipulation (editing, copying, etc.) on the behalf of the user.
How restrictive is ASP in terms of client side machine access?
I could just write a client-server app instead, but seems like that would take bit more effort.
Thx
NIK

All you need is to give the asp user account permission to the folder where the files are located. It is that simple.
[edit] my bad. I did not read OP post completely. There is no way you can access the client machine from asp.net  [/edit]

Really!!!
So I can just use something like
string path = "C:\\MyFiles\SomeFile.Txt";
File.OpenText(path);
...
in code behind?
|
|
|
|

No. Actually, ASP/ASP.NET will not have any access to the client's computer drives at all. I think only an ActiveX control might be able to access client files. Doing what you wrote would open SomeFile.Txt in the C:\\MyFiles directory of the server.

my bad. I have to read your post again. scottgp is right, you can not access client machine from asp.net. I read your post as you want to access server files.
The only way you can access client machines is through explicit permission of the use and other technologies such as activex.
sorry of the confusion, I take my earlier post back

No worries, at least I can make an informed decision.
I am kind of inclined to just do this old-school and roll my own pseudo database and write the app in straight C/++. It will be screaming fast and have no platform dependencies. The time I would have spent ramping up on SQL, .NET, DAO, IIS, etc, can be spent on implementation.
Thanks again for the input.

I have a query suppossed to return average values (SELECT AVG(DATA_VALUE)....).
However, it returns null when no data is present for the matching criteria.
I am using a data reader to read the value. like:
<br />
dr = cmdSelect.ExecuteReader();<br />
if (dr.HasRows)<br />
{<br />
dr.Read();<br />
string getAvg = dr.GetString(0);<br />
if (getAvg != null)<br />
{<br />
valArr[0] = Convert.ToDouble(getAvg);<br />
log.Add(...);<br />
}<br />
else{...}<br />
} <br />
Funny thing is - dr.HasRows is true because the query is returning a record even though the value is null. I also tried GetObject(0) instead of GetString(0), and tried cmd.ExecuteScalar() instead of ExecuteReader(), but still could not manage it. Its going to an Exception saying - "Data is Null. This method or property cannot be called on Null values."
Any help? Thanks.

all you need is DBNull[^]class
<br />
if (! DBNull.Value.Equals(dr[fieldName])) <br />
{<br />
}
