Forms Data Controls :: Can Someone Get This C# Script To Work In Vb.net?
Aug 13, 2010
Here is the link:
http://www.link-exchangers.com/webspider_src.zip
This has 6 projects and the C# spider works fine when you load it. It has the c# classes and there is also a folder for the vb.net classes. They are the same as the c#, and they do the exact same thing.
So I want to see this thing work in VB.NET. Can someone get this to work? If so, then can you upload your solution and provide a link to it like the one above?
I have been trying to get it to work for 2 weeks. My attempt to convert the code to a web site application is stuck because of a addhandler line. Here's the link to my code:
http://www.link-exchangers.com/website6.zip
I converted the form.cs to vb.net with a conversion tool. There is just 1 error. Thanks for looking at it.

I've inserted some changes into the page in which the gridview is nested, and I'm not sure what I did, but it managed to somehow disable the "Update" button operation.When I click on "Edit" - It goes into edit mode perefectly. But when I click on "Update" the page refreshes itself without doing anything (it stays in Edit mode).As I mentioned, everything worked great until now, but a small change somewhere probably gets in the way. The changes I was talking about were adding some ajax into the page, but most of it was ultimately left out. (No UpdatePanels what so over... Only a TextEditor, that I had there before).

It works in IE. I guess it could depends on that Firefox does not read I have a gridview showing images from a unc path like:
<asp:imagefield dataimageurlfield="Imageid"
dataimageurlformatstring="\ymerilderkomp_{0}.jpg" [code]...
Firefox is showing the alternativ text.

I have added AllowSorting to my Gridview but it does not work. Is it because I am explicitly creating my columns.....not autogenerating them?
<asp:GridView ID="grdEvents" runat="server" EnableTheming="False"

AlternatingRowStyle-CssClass="GridEvenText" AllowSorting="true" autogeneratecolumns="false" datakeynames="SERIAL,JOURNAL" >
<AlternatingRowStyle CssClass="GridEvenText"></AlternatingRowStyle>
<Columns>
<asp:BoundField HeaderText = "SERIAL" DataField="SERIAL" Visible="false" />
<asp:CommandField AccessibleHeaderText="LOG" CausesValidation="False"
HeaderText="LOG" SelectText="View" ShowSelectButton="True" />
<asp:BoundField HeaderText = "FIRSTOCCURRENCE" DataField="FIRSTOCCURRENCE" />

Buying books, googling, reading these and other forums. I should have gone through beginners before jumping into advanced, so please forgive the question if it is an obvious error (which I am sure it must be).I have a list bod whic has a list of roads in it. The user selects a road (and since I dont know how to just make a selection send to the formview by clicking on a road in the listbox, the user then must click on a SUBMIT buttonave 2 different surface types, you are either hauling on aggregate roads or bituminous roads - but most hauls will only have one surface type.I followed the instructions for doing my listview edit/update/insert/delete from (http://basgun.wordpress.com/2007/12/29/listview-control-in-aspnet-35-4/)

I have a repeater, and within it I have a button that shows up for each data entry. I would like it so that when I click the button, a certain action takes place, however this does not work. When I click the button nothing happens at all (the page just refreshes), however as soon as I move the button outside of the repeater, it then works.I used to get this error when when I pressed the button:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration"
But I then disabled event validation...when I disabled it I didn't get the error anymore, but the button remained useless.

I've got in a gridview with two EditItemTemplate, which are dropdownlist. for the fisrt one I need autopostback because it's used in the second.So to bind the second dropdownlist, I'm useing the GridView1_ItemUpdating, but it doesn't work. It never goes into this funktion and so on updating the column with the second dropdownlist has Null values.What's wrong?That's my code:

I would like to create a gridview that gets data from a datasource but doesn't display it in the normal fashion based on my table layout.
Example:
Table layout is:
Name Emp# Dept# Booking Code# AccessId
This is how it looks in the gridview but I would like it to look like:
Name: John Doe Dept#: 12
Booking Code#: 1234 Booking Code#: 67
AccessId: 33
What data object will give this?Gridview won't work I think.

I have a gridview with several ItemTemplates. The first contains a checkbox the rest contain textboxes. I then added dynamically some bound controls like this:
BoundField bdfPrivName = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfPrivName, "PrivName", "Priv Name");
BoundField bdfDescription = new BoundField();
clsUtilities.SetBoundFieldLeft(ref bdfDescription, "PrivDesc", "Description");
BoundField bdfLive = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfLive, "Live","Active?");
grdExisting.Columns.Add(bdfPrivName);
grdExisting.Columns.Add(bdfDescription);
grdExisting.Columns.Add(bdfLive);
I then use FindControl to locate the checkbox and textboxes and perform my logic based the result
foreach (GridViewRow gvr in grdMissing.Rows) {
mckbAny = (CheckBox)gvr.FindControl("ckbAdd");
mtxtApplyDate = (TextBox)gvr.FindControl("txtAddApplyDate");
mtxtDateToAdd = (TextBox)gvr.FindControl("txtAddDateToAdd");
mtxtDateToRemove = (TextBox)gvr.FindControl("txtAddDateToRemove");
etc.
This all worked fine. I then got a request to put the bound fields as the second, third and fourth columns, after the check box and before the textboxes. I found that this was easy to do by changing the Add's to Inserts as follows:
grdExisting.Columns.Insert(1, bdfPrivName);
grdExisting.Columns.Insert(2, bdfDescription);
grdExisting.Columns.Insert(3, bdfLive);
It looked fine of the page, but the FindControls, all of them fail to work.

I'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.
For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.
why I have to click twice for some rows? And how do I fix this?

According to the docs. [URL] There is an Separator Template for a DataList. However, when I use the built-in tool tip help, it does not show. If I manually type in a separator template it crashes my design time environment completely...
Not sure what I'm missing here. I tried an imagetemplate and a line but thats not really working because I need the image in the data field area not the headertext area.

I have a Datagrid one of the colums is a checkbox and when it is selected I' m supposed to update that row. I have a button to update this outside the Datagrid. It seems to work well for the first two rows but after that meaning starting 3 to any it just doesnt update no errors but doesnt update. When I look into the id it seems to be empty.

I have the following code in an aspx form for an asp:Repeater
<ItemTemplate>
<tr class='<%#Container.ItemIndex % 2 == 0 ? "normalRow" : "alternateRow" %>' >
<tr>
<td>
<asp:LinkButton ID="LinkButton1" runat="server">blabla
<%#DataBinder.Eval(Container.DataItem, "ListName")%>
</asp:LinkButton>
</td>
</tr>
</ItemTemplate>
Which produces a syntax error (and a sqiggle blue underline) on
<%#Databinder.Eval(Container.DataItem, "ListName")%>
the build tells me I have an invalid character in the position before the opening <%
above
This only happens after I add the conditional class for the <tr> tag
"<tr class='<%#Container.ItemIndex..."
before I add the above line (to replace the <AlternatingItemTemplate>) everythings ok.

I am making checkbox in datagrid, no matter what I try, I cannot get the right result from checkbox. Even I check or not check the checkbox, the result is false. It is like somehow the result is always the default value of the checkbox.
Here is code:
private void OrderButton_Click(object sender, System.EventArgs e)
{
CheckBox x;
foreach ( DataGridItem dgItem in DataGrid1.Items)
{
x = (CheckBox)dgItem.FindControl("OrderCheckBox");
