GridView Control Is Only Partially Populating Itself
Sep 27, 2010
[code]Whenever my GridView populates, if there is no value to return from my _dataSet for a field, my GridView stops populating after that. Shouldn't it skip that and continue populating the rest of the grid? It seems the GridView won't accept an empty/null value. is?
I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.
Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?
A panel with enabled scrollbars has many buttons. If I push the tabulation key, focus navigates between buttons.When a partially visible button has focus, the panel scrolls itself in order to completely show the button.
I have a page that has two dropdownlists(one for the locations, and the other for departments), an employee search textbox and a button. On the other page, I have a gridview. Now, what i want to archieve is that when a user types an employee's name in the textbox control, selects a location from the location dropdownlist, and a department from the departments dropdownlist, and click the button(search), the gridview on the other page must show the reqiured information of a SINGLE employee. Only one row must show.
I have created a database for the employees. I know how to do this with the autopostback but i have not tried it using a button's click. NB: the gridview should show only one row of a selected employee. I'm using ASP.NET VB
I have a vb.net website with a gridview that currently has exam questions displaying vertically in each row like this:
Name question answer ----------------------- Joe question1 answer1 Joe question2 answer2
[code]....
But I would like to change it, so that each question is a header, like this:
Name question1 question2 question3 ---------------------------------- Joe answer1 answer2 answer3 Jill answer1 answer2 answer3
This makes it more readable since each user is only listed once.I would like to stick with a gridview instead of rewriting all my code.I am actually binding my data to the gridview via some other programmers class. I am using LINQ like this:
I have the following code in my asp page: Imports System.Data.SqlClient Imports System.Data Partial Class _Default Inherits System.Web.UI.Page [Code] .....
And while the page doesn't throw me any errors, I'm also not seeing any data in my datatable.
My windows application uses a webservice (sql server backend) and now I'm trying to create a new form that has a datagridview control on it and I'm uncertain how to set it's datasource. I'm using visual studio 2005 and I have little experience using the datagridview control. In my webservice, I started the code that will be the datasource - should i be returning a dataset? I know that this code isn't correct, but I'm not sure what it needs:
<WebMethod()> _ Public Function SetMyDataSource() As DataSet Using DBConn As SqlConnection = New SqlConnection(sConnectionString) SetMyDataSource= Nothing
I have a tab control in my form and inside it I put a listview. What I wanted to do is populate the listview everytime I clicked on each tab. But I don't know how to do it.
Here is the bit of my code
Public Class Form2 Private Sub PopulateRecords() Dim TSR As New ADODB.Recordset Dim STRSQL As String = ""
I am having trouble with .net again. I have a series of 10 text boxes. I want to be able to populate them from an array and read there values into another array. In vb6 I would create a text box array with 10 text boxes / indices. I could then populate them by txtbox(i).text = arrVal(i) and to reference them arrVal(i) = txtbox(i). I am stumped I can create 10 text boxes on a form if I have to, but I want them somehow tied to each other as they were in vb6.
I know the code to find the input boxes in question.. basically the html is like so HTML <input type="text" name="username" class="inputbox"> i know enough to use WebBrowser1.Document.Forms.GetElementsByName("username") to find the text box...but I need to know how to send the contents of say TextBox1.text to the form on the web page...i can't figure it out for crap...I just assume give up and use sendkeys to tab to the textbox even thought its 80% unreliable....
I have a VB.NET application that I wish to store on a shared server. It is a GUI application that also calls a few external .dll's. I'm running into an error message that says "That Assembly Does Not Allow Partially Trusted Callers". I've seen several posts that mention I should add the following line to my AssemblyInfo.vb file:
<Assembly: AllowPartiallyTrustedCallers()>
This still doesn't seem to solve the problem. Anyone know what to do? I'm hoping to compile and store the .exe on the server for other users to access.
I decided to get rid of some of the junk in my computer, so I selected all the .tmp files and deleted (nearly) all of them. I then emptied the recycle bin... Then I set to work on trying to get some code to work (in an excel 2007 macro enabled workbook).
I now have two problems: 1) excel will not let me record a macro and 2) when I run one sub routine, excel tries to run every sub routine associated with the workbook.
other than removing and re-loading Office 2007? I'll try logging off and then logging on again - if that works, I'll let you know.
First, I changed my ILS function to be simply: Public Overrides Function InitializeLifetimeService() As Object Return Nothing End Function
Then I included this in my Program as well as A. As Timiz0r pointed out, Form inherits MarshalByRefObject, so I didn't have to include a Inherits statement on my main class (which already inherited Form). This was the big thing, because I didn't include it originally. Next, I changed my AppDomain setup to be:
Dim _ADomain As AppDomain = AppDomain.CreateDomain(Name) Dim item As New A item = CType(_ADomain.CreateInstanceAndUnwrap(GetType(A).Assembly.FullName, GetType(A).FullName), A)
With these changes I can now use separate instances of the DLL COM object as desired.
Original Question I am writing an application that creates a list of objects, each referring to a DLL, and each object placed in its own AppDomain to keep the instances of the DLL from interfering with each other. Taken another way:Program maintains a List(Of A)A is created as an instance of AppDomain using CreateInstanceAndUnwrap Each A refers to mirror.dll, which is including in the application's references
I have a transparent layer on the top of a form. I need to display only some part of that transparent form.
-edited- If you think of a map and traffic signal icons displaying on the map. There are a map image layer and a traffic signal icons layer, which is tranparent except icons. if you move the map location, the traffic signal icons should move along with. if the certain area of map does not appear on the screen by moving, corresponding traffic signal icnos should disappear as well. This is what I am trying to do here. Moving the trasparent form is straightforward, but I need to hide some portion of that transparent form.
[Map] [Traffic sig] here I need to show "fic s" part only.
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol. Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
i am devloping app in vb.net and ms sql express compact 2005 .evrything works well. but when i used a third party dll file report viewer and one from skineengine system give me the error"assembly does not allow partialy trusted callers".
at first when i used report viewer it works,but letter it throw me error,same for skineengine. so that is the case of disallowing third party custom dll files.
i even set <Assembly: AllowPartiallyTrustedCallers()> in assemmbly.info
I added an image as the background image for a form in VB.net. When I run the program, after approx. 5-6 seconds, the image partially overlays itself, as in an offset overlay of the underlying image. I never had this problem in VB6, but I did have it the other time I used a background image on a form in VB.Net.
I've been looking around on the internet for something to do this, but I have not found anything straightforward. Can anyone help? I just want to draw an image that pretty much "Highlights" an area in a bitmap. Anyone know how to do that?
I have a data table that I am updating. The table has 5 rows.The first row in the data table that has an ID of 1 will not update with new values, but the rest of the data table does update, I can't figure out why.
It is an access database I am updating, Is there a problem with my Update String? Because it updates all of my table except for the first row that has an ID of 1.
Dim sqlSSRTotalUpdateParameters As String = "UPDATE [SSRTotalChecker_" & FullName & "] SET [Totals]=@Totals,[Category]=@Category,[Materials]=@Materials, [Labour - Field Effort]=@LabourFE," & _ " [Labour - PMO]=@LabourPMO, [Labour - Supervision]=@LabourSuperv, [Labour - Administration]=@LabourAdmin," & _
I am entering data in a dataGridView, I have a column named with 6 characters.The first 3 characters are always "HHH"When I enter in this cell, Is there any way to put automatically these 3 characters and start to write in the fourth one?
this works partially but if I close the reg key as shown I get an error [code]So my question is how/where do I place the Myreg.close and OldReg.Close commands???
ive got a small code which takes a strign given by the user, searches for all folders with in a folder for matches then lists them, which is this:
vb If e.KeyData = Keys.Return Then Dim lb1s As String = Application.StartupPath() ''The folder to search in
[Code]....
The results are added to a listbox and all works great, but how do i get it to add partial matches aswell? For example if the search string is 'testing' and theres folders called 'testing on' 'testing testing' etc to show those in the results aswell?
I have a gridview that uses a stored procedure for its select statement. The stored proecedure accepts a varchar and a bit. I want a checkbox outside of the gridview to change the value of the bit. I've set the parameter to the checkbox but it doesn't seem to be working.
Out of 70 users of my application 2 are getting the following message when they to run the application... That assembly does not allow partially trusted callers. The reason for the error is that by default .net applications run from a network location have limited permissions. You need to use caspol.exe to add the network folder where your application is being run from to the Trusted Zone. If you do a search on these forums you will find plenty examples of how to do this. It is fairly simple. It will have to be done on every machine that will be running the application and a simple cmd file can be made to do this. The only difference is that I've asked our service desk to install the application to the local C drive which I believe they did.
