View 4 RepliesI've got a simple upload form. Here's my code:
[code]....
You are supposed to be able to select which gallery you want to upload a logo image for, and then select your image file and click the upload button. Here's my upload sub:

My problem is that the data bound listbox gallerySelect's selectedIndex is always -1. I know its because it's data bound but I don't know what I have to do to be able to get the value.

I am designing a program that will let me enter the name of an item to swap and adds the swap to an array list when a button Add is pressed. Once the item is added to the array list a Sub Procedure should be called which displays the contents of the array list in a list box.
The system will also allow me to remove items from the array list using a Remove button
followed by updating array list.
I have done some part which puts item into the listbox1 which i named lstSwapList.I would need some assistance on the Sub Procedure to display the Value or Description on the other listbox2 which i have also named lstContent,if a value is selected from the listbox1.
I would also want to know how to update the Listbox content,However i hv added a sample of the way i guess it may be.
Any complete solution from anybody on the Sub Procedure and the Update Swap procedure will be greately appreciated.
The script below is what i have done so far.
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub lstContent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstContent.SelectedIndexChanged
End Sub
Protected Sub lstSwapList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstSwapList.SelectedIndexChanged
End Sub
Protected Sub btnAddSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddSwap.Click
Dim SwapValue As String = "Sixty Pounds"
Dim Counter As Integer = 8
Dim SwapN0 As Integer
lstSwapList.Items.Add(SwapValue)
lstSwapList.Items.Add(Counter)
lstSwapList.Items.Add(New ListItem("300", "1"))
lstSwapList.Items.Add(New ListItem("ASP.Net", "2"))
lstSwapList.Items.Add(New ListItem("Programming", "3"))
SwapN0 = lstSwapList.SelectedValue
For Counter = 0 To -1
SwapN0 = lstContent.Items.Count
Next
End Sub
Protected Sub btnDeleteSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDeleteSwap.Click
lstSwapList.Items.Remove(lstSwapList.SelectedValue)
End Sub
Protected Sub btnUpdateSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateSwap.Click
End Sub
End Class

Sub UpdateSwap(ByVal valueA As String, ByVal ValueBAs String, ByVal ValueC As Integer, ByVal ValueD As Date)
I've got a grid view on my form that is bound to a data table at run tim. The data table is returned by a function rather than direct from the DB so I can't set the datasource at runtime.
I bind the grid in the page_load event like this:-
Code:
Dim _dt As System.Data.DataTable
_dt = _srvc.GetVinylShutters(0)
_dt.Rows.Add(_dt.NewRow)
grdShutters.DataSource = _dt
grdShutters.DataBind()
(_dt.Rows.Add(_dt.NewRow) is just there to add a blank row in, otherwise I wasn't seeing any columns at all)
I've then got the following snippet which I want to use to hide some underlying columns:-
Code:
For Each col As DataControlField In grdShutters.Columns
Select Case col.HeaderText
Case "OrderID", _
"ShutterID", _
"ModelID", _
[Code] ...
The thing is, wherever I put this it doesn't seem to hide the columns. If I break into the code I can see that grdShutters.Columns.Count equals zero althought I can see that the bound datatable has 38 columns.
I've tried the Page's Load, LoadComplete and PreRenderComplete events as well as the gridview's DataBound, RowDataBound and RowCreated events. I get teh same result in all of them. The grid doesn't actually have any columns until it appears on the screen.
I would like to know how i could display data from an itemtemplate or any other form views/data-bound controls without having it render in tables? i know theres control adaptors, but is this reliable and will it work with asp.net 3.5?

I've been using the Item Inserted event for my data controls, such as details view. I'm wondering if there are advantages to doing this with the data sources instead of the data control. There is a lot of overlap in the events provided by these two types of controls. Are there advantages to using the events raised by the data source instead of the ones raised by the data control itself. Should I be using the events raised by the data source instead of the control used to enter the data?
View 2 RepliesI have a foreign key (TeamID) in a GridView. I use a TemplateField to display it as the lookup value (TeamName) in a label, and a dropdown for editing. When row is selected and SelectedIndexChanged is fired, I want to access the TeamID. I can get the TeamName from the label. I tried putting the TeamID in DataKeyNames, but that fouled up my dropdown when saving (it reverts to the original value). So, how can I get the TeamID?
View 1 RepliesI am using gridview to display some columns with autogenerate column as 'true' and not added boundfields,headers.
And i am used stored preocedure for data source in gridview and i used dataset for gridview databind.
The gridview columns comes dynamically for each time.
When I bind my listview with a typed dataset the textbox is filled with spaces up to its max length.
For example if I have "ABC" in the typed dataset and the textbox has a max length of 5 it will actually bind "ABC ".
I know I could trim it ont he databound event, but I shouldn't have to.
I'm having a problem sorting a dropdown that I've bound to a SQL Server data source. I've narrowed the problem down to the fact that I have a static item at the top of the dropdown with the data-bound items appended afterwards. If I remove the static item (<asp:ListItem Value="-1" Text="All" />) the ORDER BY part of the select clause works fine. How can I get around this issue? What I would like is to have the "All" static item at the top of the list with the data-bound items sorted alphabetically afterwards. I'm using Visual Studio 2010 and ASP.NET 4 if it makes any difference.

I am looking for a method to format gridview bound data using javascript.
I know you can have custom formating in Eval using:
[Code]....
But I am looking for a way to perform this task on client side, rather than doing it on the server.
For example if I want to format a date field being bound in a custom way, something like emails date received in gmail. (Only show time if it is today's date [15:30] and only show day and month if it is this year date [14 Jan] and show the full date if it is not this year [10/10/2009].
So, how I use javascript to format a field (ie. custom date format or setting a control visibility)?
I have a gridview, which on the row data bound method that inserts a row when comparing values on a particular field. If the two values are different, a new row is inserted, if not no row is inserted. This coding is working as a grouping gridview, and is working correctly. However, I have problem, and problem is counting the rows between each group, which I want to display in my blank row between each group, the value of which I am holding in a hiddenfield.
When I try to do it, the first group doesn't show the result, but is displayed on the next group. I am pretty sure that I am doing something wrong. My approach is that if the value between the last row and the existing row are different, then the value is one, on the next row data bound event, if the values are the same then the value is increased by one, else the value is one because it is a new group. Here is my code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
Table tbl = e.Row.Parent as Table;
TableCell cell = new TableCell();
CheckBox chk = new CheckBox();
Label lbl2 = new Label();
HiddenField rowValue = new HiddenField();
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Visible = false;
}
else
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Session["count"] = 1;
Label lbl = (Label)e.Row.FindControl("lblValue");
string str1 = ((Label)(lbl)).Text;
string prevStr= (string)Session["previousStr"];
if (prevStr== str1)
{
lbl.Visible = false;...................
I have some data which contains angle brackets in some of the fields.Even if properly escaped as <: or > (or even the hex codes), or contained in CDATA, in Visual Studio 2005 ASP.Net, the field data is being truncated at the first angle bracket. If I replace the data with curly braces, it displays fine.Is this a parser defect in the TreeView control? I can use Response.Write and see that the data provided by the XmlDataSource is fine. Example:
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
This truncates right after TT Description. If I change to curly braces or parentheses, it displays fine.
I have a web form, and an "add vendor" button. Click the button, a modal dialog pops up (ajax:ModalPopupExtender). User selects one of two radio buttons which shows a data bound asp:View in an update panel - this view is data bound to a single row and must be populated by the user. However I also want to provide a cancel button which should close the modal dialog and reset the bound view.
However what is happening is that the ModalExtender closes, but when the "add vendor" button is presented again, it's still bound to the same data. Do I need to clear my data source? How so I reset the forms/views so that when the 'add vendor' button is clicked again the form is presented as it should be (IE the 2 select options, picking one re-binds the asp:View)?
is there a way to get the PropertyName of a data bound control? For example:
I have a text box like this:
[Code]....
How can I get the info that this text box is bound to the property with the name "Test"?

View 1 RepliesI have a dropdownlist in the edititemtemplate of a detailsview. The dropdownlist is bound with an objectdatasource. The detailsview is bound to a seperate objectdatasource which connects it to the insert method. When the page loads the dropdownlist is bound properly.

I am using a DetailsView component (dvExpertsData) bound to a SqlDataSource (sqldsExpert) with a field that has a ItemTemplate (Field[9]) with a checkbox component (chkbxAvailable) assigned to it. The idea is to have only this item updated out of all the data presented, so I do not have a requirement for editing an other data. sqldsExpert's SELECT query is a call to a stored procedure as is the UPDATE query.
