hi all,
I have ListBox with multiple item selection mode on. I have problem reading data after POSTBACK. I mean I do not know how to get selected value from Listbox if there are more then one selected Items.
Thanks

|
|
|
for(int i=0;i<=ListBox1.Items.Count-1;i++)
{
if ( ListBox1.Items[i].Selected )
}
|
|
|
|
|
Dim array(ListBox1.Items.Count) As String<br />
Dim i As Integer = 1<br />
<br />
<br />
For index As Integer = 1 To ListBox1.Items.Count - 1<br />
If ListBox1.Items(index).Selected Then<br />
<br />
array(i) = ListBox1.SelectedValue<br />
i = i + 1<br />
End If<br />
Next

I am trying to include a Javscript file in all of my pages using the following line, written into the section of my master page.
<script runat="server" language="javascript" src="~/Javascript/MAD.js"></script>
For some reason I get the following error
Parser Error Message: Cannot use 'javascript' because another language has been specified earlier in this page (or was implied from a CodeFile attribute).
Any ideas how I can get around this as I need the runat tag and the ~ root symbol to find the file from all directories.
Thanks

Just Remove runat="server" code

"as I need the runat tag and the ~ root symbol to find the file from all directories."
Did I not make that bit obvious enough?
Lose the runat tag and the ~ symbol means nothing a will never work. Sometimes pages are one folder level up sometimes two, sometimes three. Therefore I have to use the runat attribute.

You're right that you need the runat="server" for the ~ symbol to work, however it will never work like you want it to, because then it will be treated as server-side script. So another approach is recommended. One idea would be to use full url paths, which could be constructed in the codebehind. Like:
string webroot = Request.Url.ToString().Replace(Request.Path, String.Empty);
Page.ClientScript.RegisterClientScriptInclude("mad", webroot + "/Javascript/MAD.js");

Hi,
In my application i have a "asp:dropdownlist" control on whose selectedIndexChange event i need to call a javascript function.
But i get build error:Too many characters in character literal.
If i remove 'runat=s"server" then its doesn't give build error, but on load of page, it doesn't show the control.
<asp:DropDownList runat="server" ID="ddListSelect" EnableViewState="true" CssClass="ddListStyle"
style="z-index: 102; left: 384px; position: absolute; top: 40px" Width="117px"
OnSelectedIndexChanged="javascript:openPopupNew('frmPopup.aspx')" >
<asp:ListItem Value="Spain">Spanish</asp:ListItem>
<asp:ListItem Value="Turkey">Turkish</asp:ListItem>
<asp:ListItem Value="England">English</asp:ListItem>
</asp:DropDownList>
What can i do get rid of the build error, n for the javascript code to get executed successfully?
Could anyone plz help?
Thanks

there is no 'onclick' event for an "asp:dropdownlist"
and i need to show popup when user selects an item from the dropdownlist only..not on click of dropdownlist
|
|
|
|
|
The OnSelectedIndexChanged is server event and not suitable for your purposes. The client-side event you are looking for is onchange. So in the codebehind write:
ddlListSelect.Attributes.Add("onchange", "javascript:openPopupNew('frmPopup.aspx')");

if you just want to only show records(not 4 editing) to user then give me db query
|
|
|
|
|
Yes i want to show only 4 record in one row in table contain its pg information then this information should add below next row. my data database query is as below.Its not for editing.
str = "select BachlorDegree,B_Grade,B_PassingYear,B_Institute,LangKnown from EducationalInfo where UserId=" & cndid
this shows first 4 column.

if u r trying to get only one candidate record of Grd and PGrd from 2 different tables and show it to grid then try this type of logic
dtGrd (this table contains Graduation info agiant CandidateID)
dtPGrd (this table contains PG info agiant CandidateID)
dt (this table contains that columns which u want to show from both ur above tables)
dim dr as DataRow<br />
<br />
if dtPGrd.rows.count>0 then<br />
<br />
dr=dt.NewRow<br />
dr.item("ColumnName")=dtPGrd.rows(0)("ColumnName")<br />
dr.item("......<br />
<br />
dt.rows.add(dr)<br />
<br />
end if<br />
<br />
<br />
if dtGrd.rows.count>0 then<br />
<br />
dr=dt.NewRow<br />
dr.item("ColumnName")=dtGrd.rows(0)("ColumnName")<br />
dr.item("......<br />
<br />
dt.rows.add(dr)<br />
<br />
end if<br />
<br />
Grid_View1.DataSource=dt<br />
Grid_View1.DataBinding()
if u want to do this for many candidate then use this logic in lop
Hope it's helpfull for you

I have the following function writen in asp.net with vb script. when click the update button everthing is getting updated except "date" I tried to update using date.parse also but no use. The same code was woking fine previous say a week back. I have not made any changes also. But I am not finding any reasons for this. this is happening whereever i have used date. Insertion or updation of date and searching based on date is not working.
Function update()
Dim flag As Boolean
flag = False
Dim tran As SqlClient.SqlTransaction
Dim a As String
a = txtexpdate.text
Dim d As Date = Date.parse(a)
If txtremark.Text.Trim = "" Or lblcustname.Text.Trim = "" Or txtcustdrno.Text.Trim = "" Or txtbore.Text.Trim = "" Or txtstroke.Text.Trim = "" Or txtapplication.Text.Trim = "" Or txtrod.Text.Trim = "" Or txtpress.Text.Trim = "" Or txteqpmodel.Text.Trim = "" Then
lblstatus.Visible = True
lblstatus.ForeColor = Color.Red
lblstatus.Text = "Fields can not be left blank !"
Exit Function
ElseIf IsNumeric(txtbore.Text.Trim) = False Or IsNumeric(txtstroke.Text.Trim) = False Or IsNumeric(txtrod.Text.Trim) = False Or IsNumeric(txtpress.Text.Trim) = False Then
lblstatus.Visible = True
lblstatus.ForeColor = Color.Red
lblstatus.Text = "Bore,stroke,rod and working pressure should have numeric value !"
Exit Function
Else
If dbconn.State <> ConnectionState.Open Then
dbconn.Open()
End If
Dim comm As New SqlCommand()
comm = dbconn.CreateCommand
tran = dbconn.BeginTransaction
comm.Transaction = tran
Try
comm.CommandText = "update D_proposal set cust_drw_no='" & txtcustdrno.Text.Trim & "',cust_name='" & lblcustname.Text.Trim & "',typ_cyl='" & txttypcyl.Text.Trim & "',cushioning='" & txtcush.Text.Trim & "',bore='" & txtbore.Text.Trim & "',stroke='" & txtstroke.Text.Trim & "',application='" & txtapplication.Text.Trim & "',category='" & txtcat.Text.Trim & "',sada='" & txtsada.Text.Trim & "',rod='" & txtrod.Text.Trim & "',wrk_press='" & txtpress.Text.Trim & "',eqp_mdl='" & txteqpmodel.Text.Trim & "',mounting='" & txtmounting.Text.Trim & "'where pno='" & lblpno.Text.Trim & "'"
comm.ExecuteNonQuery()
'comm.CommandText = "update D_task_det set associate='" & txtassociate.Text.Trim & "',exp_date='" & txtexpdate.Text.Trim & "',remark='" & Replace(txtremark.Text.Trim, "'", "''") & "' where pno='" & lblpno.Text.Trim & "'and task='" & lbltask.Text.Trim & "'and leader='" & txtleader.Text.Trim & "'and revision='" & txtrevista.Text.Trim & "'and reassign='" & txtreassigsta.Text.Trim & "'and hold='" & txtholdsta.Text.Trim & "'"

Catch ex As Exception
tran.Rollback()

Finally
comm.Dispose()
dbconn.Close()
End Try
Return flag
End If
End Function
Private Sub btnsave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsave.Click
update()

What is your date column datatype in Database ? Have you tried running the same query in query analyzer ? If so what error you got ?
|
|
|
|
|
Now it is working. I have changed the enableviewstate property of all the controls to true and readonly property of datetextbox(text boxes where we have date value) to false. But i want datextbox readonly. What can I do for this?

If U create your website page with ".aspx", then U must use AJAX control in it. Coz game site must Have interactive interface.
If not U can make your website from macromedia Flash

Hi,
I have two problems here.
1. When I open a page, when some criterias met, I want all the textbox, drop down box etc to be disable. I know I can disable them one by one but there are just too many of them and I have 10 similiar page, so I was wondering whether is there anyway that I can use a few line of codes to disable all of them.
2. I am using server side window.open as below
public void Window_Open(string url, bool resize, int height, int width, int scrollbar)
{
System.Web.HttpContext.Current.Response.Write("");
System.Web.HttpContext.Current.Response.Write("window.open('" + url + "','','resize=" + resize + ",height=" + height + ",width=" + width + ",scrollbar=" + scrollbar + "');");
}
Which works well but when it will refresh my parent page and cause all my fonts to become larger. I need to hide the link button which call Window_Open(...), so I have to put it as server side control so it only appear when some criterias are met. So is there anyway I can stop the page from refreshing from the server side?
Thanks in advance.
J Liang

1: Place the controls you want disabling inside a panel and disable the panel.
