I'm trying to add a parameter at the end of a url obtained from the database as follows:
This is giving error because of the ID value, which is an integer...how can I convert it to string here? I can do it in code behind, but I just want to know how it can be done within the Eval function...
NavigateUrl
='<%#Eval("Filepath") + "&ID="+DataBinder.Eval(Container.DataItem,"ID")%>'
I have a stringvariabel in a form I shall insert in a SQL database in a integer field. I try to convert it in the parameterlist:
myComm.Parameters.Add("@UtstyrID",
SqlDbType.Int).Value =
Convert.ToInt32(e.Record["UtstyrID)"]);
but it only store the value 0 and not the value of the e.Record["UtstyrID)"])
I have a datagrid and I set up the paging based on how many rows there are like this
With dgBookings
.AllowPaging = True
.PagerStyle.Mode = PagerMode.NumericPages
.PagerStyle.PageButtonCount = 5
.PageSize = 5
End With
Is there a way to set the horizontal-align in the code too I tried adding this
.PagerStyle.HorizontalAlign = Right
and I get this errorArgument not specified for parameter 'Length' of 'Public Function Right(str As String, Length As Integer) As String'.
Currently using VS2008, VB.NET, SQL. I have a FormView from a Data Source that is getting some fields that are stored as Decimals in the SQL Database.
I am grabbing the field from the FormView as such:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
I need to take this value, and convert it to an Integer, then send it along to an API. I have the API Calls done, tested and working, but I'm getting an error as when it is getting this value, the API is returning "Must be an Integer" error.
What I have tried so far:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
Dim AvgTicket1 As Integer
AvgTicket1 = Double.Parse(AvgTicket.Text)
Do something with AvgTicket1
I have also attempted to Round the Value, then convert it and call it - no luck.
Checking the value of AvgTicket1 (Writing it out to a Label or Response.Write) shows "100", where the database value was 100.00. But the API is still getting 100.00, apparently. Any other conversion method that I've attempted states errors that the Label cannot be converted to Integer.
What are some methods I can successfully convert this value to an integer from a label?
I am being passed a date in this format DepartDate=40683, in vb.net however i cant figure out how to convert the integer into a regular date.
View 2 RepliesWhen I try to run the following code it always spits out the hex representation, not the integer representation. Most of the examples I found on MSDN said this should work. What am I missing?
var stringBuilder = new StringBuilder("8");
int j = 0;
foreach (char item in stringBuilder.ToString())
{
j = Convert.ToInt32(item); //returns 38, need return to be 56
}
edit I should have made clear that I know the difference it's returning the hex value. I'm outputting the value to a file, and in that file, it still shows the hex value, not the integer, so I don't think it has anything to do with the debugging environment. edit2 Looks like a PEBKAC problem. Looked at the code that was writing to the file, and it was using a .toString("X") method, changing it to a Hex value. The fact that it was hex in my debug environment was what confused me.
int no = int.Parse(hidden_field.Value.TrimStart()); it cause the error: input format was not in correct format. how to fix it?
View 5 RepliesI have the following code reading in my xml file and sorting it by ID:
Dim ds As New DataSet
ds.ReadXml(Server.MapPath("/posts.xml"))
Dim dv As New DataView(ds.Tables(0))
dv.Sort = "id desc"
The only problem is that it isn't sorting it numerically (it's sorting it alphabetically 1, 10, 11, 2, 24, 3, 4...). It appears as though I have to convert that column into integers, but I haven't been able to figure out an efficient way to do that.
im ds As New DataSet
ds.ReadXml(Server.MapPath("/App_Data/posts.xml"))
'ds.Tables(0).Columns(0).DataType = TypeOf(Decimal)
Dim dv As New DataView(ds.Tables(0))
'dv.Sort = "date"
I want to split a string that taking both string and integer values like (Cmp_12). I want to use them in Separately.

my link button -
<asp:LinkButton runat="server" ID="lbtnEdit" Text="edit" OnClientClick="javascript:msgDisp('<%# Eval(LocationId).toString() %>')" />
and the javascript msgDisp is-
<script type="text/javascript" language="javascript">
function msgDisp(lid) {
alert(lid);
}
</script>
but it is not giiving LocationId in pop but the whole string <%#......%> is comin in popup message. How can I pass Eval values in javascript.
I have the following:
<EditItemTemplate>
<asp:Button ID="wrqst_need_ind_btn" runat="server" Text = "Create WR"
onClientClick="javascript:popUp('popup_createWR.aspx')"
CommandArgument='<%# Eval("dvc_nm") + "|" + Eval("data_orgtn_yr") %>'/>
</EditItemTemplate>
I want to pass in as two additional params the Eval("dvc_nm") and Eval("data_orgtn_yr") to the popup function.
UPDATE:
I tried by removing the single quotes from insode the <% %> tags. Which gave me this:
onClientClick='<%# "javascript:popUp(popup_createWR.aspx," + Eval("dvc_nm") + "," + Eval("data_orgtn_yr") + ")" %>'
which complied, but when I clicked the button I did not get a pop up, the page just posted back and reloaded and said errors on page, but no popup...
I am currently binding a Nullable bit column to a listview control. When you declare a list view item I need to handle the case when the null value is used instead of just true or false.
<asp:Checkbox ID="Chk1" runat="server"
Checked='<%# HandleNullableBool(Eval("IsUsed")) %>' />
Then in the page I add a HandleNullableBool() function inside the ASPX page.
protected static bool HandleNullableBool(object value)
{
return (value == null) ? false : (bool)value;
}
This works fine but I need to use this in several pages so I tried creating a utility class with a static HandleNullableBool. But using it in the asp page does not work. Is there a way to do this in another class instead of the ASPX page?
<asp:Checkbox ID="Chk1" runat="server"
Checked='<%# Util.HandleNullableBool(Eval("IsUsed")) %>' />
<asp:TemplateField HeaderText="Is Activate ?">

I want to Show that, when IsActivated is true text will be "User Is Active" and when false , the text will be "User Is not activate" ...
