hi all,
got a nasty one. Trying to get the selecteditem that a user clicks in an gridview, however the gridview is in an update panel. At first i thought the problem was with the session state - but what actually happens is the update panel does a postback sends everything back to the server but the server only sends back whats in the update panels.
The main problem is when a user clicks the button, this causes an asynchronous postback the event fire in a different order to normal so i detected the button that was pressed after the page load event has fired and therefore miss capturing from session.
Has anyone solved this?
Here is my code: -
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
<br />
Dim selectedItemID As Integer = CType(Session("SelectedItemID"), Integer)<br />
<br />
End Sub
Protected Sub itemsGridView_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles itemsGridView.RowCommand<br />
<br />
Try<br />
<br />
Dim selectedItemID As Integer = CType(Session("SelectedItemID"), Integer)<br />
'Check for custom CommandName Argument<br />
If e.CommandName = "SelectItem" Then<br />
<br />
' Convert the row index stored in the CommandArgument<br />
' property to an Integer.<br />
Dim index As Integer = Convert.ToInt32(e.CommandArgument)<br />
<br />
' Retrieve the row that contains the ImageButton clicked<br />
' by the user from the Rows collection.<br />
Dim row As GridViewRow = itemsGridView.Rows(index)<br />
<br />
' Get a handle on ImageButton clicked<br />
Dim imgbtnItem As ImageButton<br />
imgbtnItem = row.Cells(13).Controls(0)<br />
<br />
<br />
selectedItemID = row.Cells(0).Text<br />
<br />
'Session("SelectedItemID") = selectedItemID<br />
<br />
End If<br />
Catch ex As Exception<br />
MsgBox(ex.Message.ToString, MsgBoxStyle.Information, "ItemsGridView RowCommand Error!")<br />
End Try<br />
<br />
<br />
End Sub

ASP.NET defaults the upload limit to 4MB. You can increase this in the web.config file. See this[^]

Hi
You can upload larger files by changing maxrequestLength in Web.config section.
<configuration>
<system.web>
<httpruntime executiontimeout="1800" maxrequestlength="400000">

I don't know how to handle specific to textbox but you can enable it for the whole page add removed="return false" to the body tag and check
If you don't want alter the textbox value better to make that textbox readonly

Most of the GDI+ classes are slow and performance costly. You should call it's Dispose() method when you are done with the instance. This forces instant memory claim. Wrap your instances in "using" keyword, which ensures the disposal.

Hello all, I have two queries related to user control.
One, how can i include a .js and .css file in an .ascx page? Are we allowed to use tag, if yes then can I just include them as usual by using tag?
Two, I have an HTML(not aspx) page which i want to convert to a user control. I have javascript functions being called on the "load" and "onmousedown" event for the body of the HTML page. But since user contriol do not have body so how do I implement it...?
Please help...

Yes you can do that. Or you can include them in the page where you will use them.

HTML you can convert to user controls. Since it doesn't have a body tag, you should call OnLoad events inside the page where you use them.

Hi,
i created one user control, in that control i called function. But it is not working when i used that user control in my form.
But the same coding can be working in pages.
Can any one help me?
In my user control i created one table like this,
I write the code in server side as follows,
HtmlTableRow htr,htr1;
HtmlTableCell htc;
htr = new HtmlTableRow();
htc = new HtmlTableCell();
htc.InnerHtml = "Sutheesh Visible";
htr.Cells.Add(htc);
SampForum.Controls.Add(htr);
htr1 = new HtmlTableRow();
htr1.ID = "Hello";
htc = new HtmlTableCell();
htc.InnerHtml = "Sutheesh Invisible";
htr1.Cells.Add(htc);
htr1.Style.Add("display", "none");
htr.Attributes.Add("onClick", "ShowHide('" + htr1.ClientID+ "')");
Ftable.Controls.Add(htr1);
JavaScript:
function ShowHide(cell)
{
alert(cell);
if(document.getElementById(cell).style.display=="none")
document.getElementById(cell).style.display="inline";
else
document.getElementById(cell).style.display="none";
}

Thanks for ur reply friend.
The page cannt find document.getElementById(cell), because it (cell) is created in usercontrol.

Have you checked the page source ? Verify the alert is giving the same name which is there in the page source.

Thanks Navaneeth, Finally i got the answer by ur clue, i saw the page source it was different from the id. It includes usercontrolname_id.
Now my user control is working fine.... Thanks alot..
