i need to display some text boxes, and have the ability for the user to "add another row"
i tried a datalist and a repeater, but it does not show anything at all, when the controls are blank.
<asp:DataList id="dlIso" runat="server" RepeatColumns="2" RepeatDirection="vertical" >
<ItemTemplate>
[Code]....
so in this case "test" does now show at all..
what is the best way to get this accomplished?
My button gets a commandargument of empty string even though the commandargument gets set. I have verified it gets set to the correct ID in debug mode, but then when I go to access this commandargument later in the repeaters ItemCommand event the commandarguments are empty string. And I have no idea why. I end up getting a sq foreign key exception because it is inserting an ID of 0 from the empty string values. There is no other code regarding the repeaters buttons that would be resetting it.

<asp:Repeater ID="repeaterAddresses" ViewStateMode="Enabled" DataSourceID="sqlFacilityAddresses" runat="server">
<ItemTemplate>
<Select:Address ID="AddressControl" runat="server" />

I have placed a button on data repeater (called datarepeater1) so that it is repeated with other controls. When I click this button, How do I access/reference the text value of a textbox control called TxtAnimalID on the same row? (This would be something like the current row I am on).
View 2 RepliesI need to be able to trigger events when a user clicks on a radio button that is generated within an control on my page.I've added an OnSelectedIndexChanged handler to the RadioButtonList and created a function in my code behind that should handle the selection of the RadioButtonList's ListItems, but I don't know how to pass a value to that function.Here's my code:
<asp:Repeater runat="server" ID="rptQuestions">
<HeaderTemplate><table width="100%"></HeaderTemplate>

I'm using a repeater ListOfArticles and have controls inside it like ddlSizes and btnSelectArticle. Normally you can just double click the control and in the aspx.vb page you can specify an action. I have heard something about Findcontrol, but can't figure out or find much information that I understand. I don't want to sound like an ass, but I would really prefer help for the aspx.vb page and not in C# or Javascript.
An example of what I'm trying to do is, once you've clicked btnSelectArticle the label lblSelection receives the following values Amount: txtAmount - Size: ddlSizes.SelectedValue.
<asp:Repeater ID="rptListOfArticles" runat="server" DataSourceID="objdsArticleList">
<asp:DropDownList ID="ddlSizes" runat="server" AutoPostBack="True"

Does datarepeater control has a bug? I tried to anchor a text box control inside the DataRepeater.Item, but it didn't work. At the property window, I set Anchor = Top, Left, Right. Anchor Right doesn't work properly.
View 1 RepliesI am not able to get an empty point to break the line and be skipped in MSchart. I am using a spline chart for the data and when it reaches an empty point I want to line to break. I have tried setting the marker-style and border-width to nothing and 0 and also tried setting them in code but no success.
View 1 RepliesI have a Data Repeater to which I need to add x number of images depending on their existence in the database.I need the images added within hyperlinks for Javascript functionality. In order to dynamically add the hyperlinks and images I have placed them within a panel in the data repeater and am adding them in the ItemDataBound event.The problem is that only the first image is being written to the datarepeater.[code]

I have a database with lots of fields, some of which are still empty and are to be filled in at a later stage. Is there any way of writing an IF statement (or any other method) that will allow these empty records to be 'shown' in my textboxes in Visual Studio, without receiving the error:
Conversion from type 'DBNull' to type 'String' is not valid.
I got a text box and a panel.The textbox is at the bottom, and the panel is above it, making a open white space above it.The thing I want, is that when i type "run" into the textbox.The empty space should start displaying messages of its actions.Just like in command prompt.If you open a cmd window. (make it small) then type in "ipconfig" (as an example), the text that shows up, makes the scroll bar, follow it down.

I am using VB.Net with Framework Version 2.0.
Ive got a Form application in VB.NET.I have many text boxes on one form (about 20). Is there anyway to check them all at once to see if they are empty instead of writing out a massive line of code to check each one individually such as
If txt1.text = "" Or txt2.text="" Then
msgbox("Please fill in all boxes")
I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1
row2 tour 1
tour1 subtotal
[Code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater
I am running Visual Basic 2008 express edition. My controls toolbox is empty. There are also no properties for the form controls on my project. Just blank. I have removed the .net framework v2.0. I had the .net framework v3.5 installed at the time, and thought I didn't need the older version (v2.0). Do I need v.2.0 for the tools? If so, where can I get a copy? What's the filename called?
View 2 RepliesI have a parent repeater with nested repeaters.My problem is I am trying to use 'Next' and 'Previous' buttons to rebind my repeater (rptTabContent) and thus the inner repeaters also, but when I try to manipulate the state of these links during the ItemCommand event they are overwritten by the bind.

I am dynamically displaying some controls in a TableLayoutPanel. The problem I'm faced with is that I want the controls to be displayed in a specific order, instead of just filling the TableLayoutPanel from 0,0 till the end of the panel.
I have 5 columns and 5 rows.
1st row is for buttons only, 2nd row for combobox, 3rd row for radio button.
I want it to be displayed like this:
Button1 Button2 Button3
Combobox1 Combobox2
RadioButton1 RadioButton2 RadioButton3 RadioButton4 RadioButton5
[Code]....
I have inserted a form into my project that a friend sent over. The form works but if I add more controls to it they are not displaying.
The controls are all there in the <form>.designer.vb file but are simply not displaying when I run the form.
I have looked around the net but can find no reference to a similiar problem.
I've tried using the method in the link below, but unfortunately this only works with .exe files. I want to be able to display icons from all filetypes in picturebox's.

So I was wondering if maybe there's a quick edit I can do in the method above to make it work, or even a completely different way of doing it?
I have a report that i'd like to display an Image for each record. But not all records have an image. The problem I have is that the last image is then repeated in the next record.
I would like to know how to have any empty field display a default image.
Code I have in report
Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
Me.Image21.Properties("Picture") = Me.PhotoLink
End Sub
Photolink is a textfield and Image21 is an Image.
i am creating TableLayoutpanel dynamically and placing labels in each cell..and i given label Dock Property Fill. all or ok But TableLayoutpanel Right side Border and Bottom Side border not displaying properly.
View 5 RepliesAssume you have controls A, B, C, D and E all with a Visibility property. You also have states 1,2,3,4,5 and 6 in which various combinations of your controls would be displayed. Currently this is being handled by switch statements for each state: i.e.
Select Case PageState
case "1"
a.visible = false
b.visible = true
[code]....
As you can imagine, this becomes a pain as every state needs a show/hide statement for each control. How can I refactor this so that adding controls and/or states becomes trivial?My first instinct is to extend the control and add a collection of states that it should display for but this sounds like overkill.
Edit:I was deliberately vague in my question in case this has other implications. In my current instance the "controls" in question are ASP Panels. Does that change anything?
After click the ok button all controls of displaying data should be clear in dataentry form. If i enter some data in the Combobox or Textbox for saving the data into the database, If i click the OK button all controls of displaying data should be clear, B`se i want to enter next record, so how can i do this?? Is there any Refresh Property is there?

I have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

This must've have been asked before but I couldn't locate it. In a mixed code project (VB and C#) we were debugging some old Visual Basic code where a statement as follows could be found:
If Request.Params("xxx") <> "" Then
'do something
I considered this a bug as Request.Params could be null, in which case the statement would've become false which wasn't the idea. So I thought. I just found out, -- probably for the tenth time and I will keep forgetting -- that the following two statements are not equal, while Nothing in VB should be equal to null in C# (thought I):
if(String.Empty == null) // always false
If String.Empty = Nothing Then ' always true
Should I dismiss this as a typical Microsoft backward compatibility effort, or should I consider this a huge error in the VB.NET compiler? Does anybody know the Microsoftean opinion on this oddity?
