You can't assign anything to the FileName property of the upload control. That would be a serious security hole, as you could access the contents of files on the client system by automatically uploading them.
The user has to select the file to upload.
Despite everything, the person most likely to be fooling you next is yourself.

I have a nested gridview using javascript to show and hide a child grid, I would also like to show or hide ALL child grids by clicking a checkbox. The javascript I am using is pretty popular, as you can see I have it set to have all children open, I populate the plus and minus button from the RowDataBound event because not all my parents have children. My javascript knowledge is very bad, what I need help with is:
How to make the ShowAll function, the HideAll function, and the call to it from the checkbox, also, how to sent the count to the functions because not all my parents have children. Thanks in advance for any help.
--Javascript--
<script language="javascript" type="text/javascript">
function expandcollapse(obj,row)
{
var div = document.getElementById(obj);
var img = document.getElementById('img' + obj);
if (div.style.display == "block")
{
div.style.display = "none";
if (row == 'alt')
{
img.src = "../../images/plus.gif";
}
else
{
img.src = "../../images/plus.gif";
}
img.alt = "Expand Child Tasks";
}
else
{
div.style.display = "block";
if (row == 'alt')
{
img.src = "../../images/minus.gif";
}
else
{
img.src = "../../images/minus.gif";
}
img.alt = "Close Child Tasks";
}
}
function ShowAll()
{
}
function HideAll()
{
}
</script>
--RowDataBound--
if (e.Row.RowType == DataControlRowType.DataRow)
{
GridViewRow row = e.Row;
int taskID = (int)DataBinder.Eval(e.Row.DataItem,"TaskId");
if(taskmanagement.GetChildrenTasksCount(taskID) > 0)
{
showChildButton.Attributes.Add("style", "display:block;");
GridView gv = new GridView();
gv = (GridView)row.FindControl("grvChildGrid");
ClientScript.RegisterStartupScript(GetType(), "Expand", "<SCRIPT LANGUAGE='javascript'>expandcollapse('div" + taskID + "','one');</script>");
gv.DataSource = taskmanagement.GetChildrenTasks(taskID);
gv.DataBind();

Please could you paste your code.
Are you sure are reading all the records.
How are you binding the data?
|
|
|
|
|
objDDL.fillDDL(ddlState, "codstate", "", False, Constants._DDL_Default_Select)
objDDL.fillDDL(ddlDistrict, "CODDistrict", "", False, Constants._DDL_Default_Select)
objDDL.fillDDL(ddlCity, "CODcity", "", False, Constants._DDL_Default_Select)
using ddlstate,district,city tables
|

First thing is Debug the application
And see what you are getting from database.
Thanks and Regards

dont call sqlReader.Read()
just set the datasource for the dropdown, the DataTextField, and the DataValueField, to whatever column you want them to be(the text field is what is displayed) and call the DataBind function on the drop down.
Please remember to rate helpful or unhelpful answers, it lets us and people reading the forums know if our answers are any good.

|

the person above has given the exact answer....this is what msdn has to say about the Reader.Read()----Advances the reader to the next block of data in cases where the reader contains more than one block.So the first call gets u past the first record i believe.

Hi
I am trying to use the ajax timer control.
I have got it working in my app so the time is running at real time i.e. updating every second.
The problme is the rest of my app is grinding to a halt because of the timer control.
The timer control sits in the master page but every other page takes a lot longer to load than before
Any ideas?
thanks

Also my controls that have autopostback now dont work
|
|
|
|
|
Might be your timer control is taking more CPU time than other process.
Its total gyess not sure 
[Edited]
You should always remember that even though partial updates are not as heavy on the server as real postbacks, the server is still contacted, and when using timers, you may get a lot of partial postbacks, which can slow things down. Always use as high intervals as possible, and consider if contacting the server is really necessary or not.

Does the ajax control run the page load code when it refreshes even a small part of the page?
|
|
|
|
|
|
So putting a timer control on a page which has controls which autopostback is not a good idea yeah?
How annoying, I will have to scrap the timer control.
Be good if you could re-load the page without the whole code running

Instead of document.getElementById('LeftTD').style.display='block';
Have you tried:
document.getElementById('LeftTD').style.display='table-cell';
Hope this helps,

hi all,
I used this site a reference for many thing . I got answers from other,s post itself .Rarely i posted questions
Now i am facing a problem . I were using module variables in application .Now we chnaging to session varibles
I am using an object of a class in each webpage . since i dont want to declare that object in each function i am declaring at the form level
when i was using module variable it was not giving any error
i changed it to session variable . Now it s giving an error
error is pasted below
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.
so i added EnableSessionState="True" to page directive . then also it is giving error
this is the code that gave the error
Partial Public Class Chart
Inherits System.Web.UI.Page
Dim ObjCls As New MVCTM.ClsFetchApply("", Session("country"))
Dim OraMod As New MVCTM.ModMain(Session("country")) Dim dt As New DataTable()
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
when i changed the declaration in to form load it is not giving any error

No. When the Page object is created it's too early to use Session variables, as it's determined later if the page is sessionless or not.

Can you not say something like:
Dim ObjCls As MVCTM.ClsFetchApply
Dim OraMod As MVCTM.ModMain
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ObjCls = New MVCTM.ClsFetchApply("", Session("country"))
OraMod = New MVCTM.ModMain(Session("country"))

Hi All,
In a .aspx page i run some heavy javascript code that takes 7-10 seconds to be completed,before starting
this processing i display a .gif image,In this image a dot automatically rotates.This image shows the user that
processing is being done and he should wait.Rotation of dot is in-built in this image.
But when javascript code runs,in image this dot stops rotating.
i just know that this happens due to heavy javascript code.
Please provide some solution or some other alternative.
Thank You.
