I've been programming with VB for a little over 2 years, however have never had any formal education. So the extent of my education is as follows:
I want to know how to do a mouseover for an image on my webpage, I look online for someone who's done it in VB and I try and duplicate their code and then play with it until I get the results I want.
So as you can see there is a wealth of VB coding that simply escapes me because I just haven't desired to include it or needed to include different aspects of VB in my programs / web developments. What I want now is big enough that so far (one week of online searches) I've uncovered no site or forum that has given me a tutorial on how to go about implementing what I want into my Microsoft Web Development project. The old sources for information are only good for one or two aspects of a coding procedure, not an entire overhaul of my current .aspx files. Not to mention a bias towards hard coding in pure <html>, I get a lot of that when someone doesn't have the patients to address my question.
When I created my new project it automatically populated an Accounts folder with a Changepassword.aspx, Changepasswordsuccess.aspx, registration.aspx, and Login.aspx. I've successfully prevent the program from logging in the user after they register with a simple " ' " before an authentication line in the registration.vb code; however, the login.vb code and the login.design.vb code is simple beyond me, and I've yet to find a site that spells it out for me.
I've created an online test. However, the intent is to have the users only take the test once, thus after they register with their email address I want my site to send them an email with an account activation link. Once they click on this link by visiting their inbox they can then take the test.
How to change a column from hyperlink field to button in Gridview?
My current code is as follows
<asp:TemplateField HeaderText="Click">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# Eval("ID", "Detail.aspx?ID={0}") %>'
Target="_blank" Text="Detail"></asp:HyperLink>
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</asp:TemplateField>
I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Below is my code
<asp:GridView runat="server" ID="gridManageClients" AutoGenerateColumns="False" OnRowCommand="gridRowCommand">
<Columns>
<asp:BoundField DataField="Clientid" ItemStyle-Width="75px" />
<asp:BoundField DataField="ClientName" ItemStyle-Width="300px" /> [code]...
Ive got a list of records in a gridview (from an SQLDataSource) where a field value is set to True. I've also added a "reset" button in a template field at the start of the row in the Gridview.
What I would like to do is allow the user to click the reset button on a particular row and 'reset' the true value to 'false' (updating the source data).
I created a gridview that is bound with an SQL datasource - I added a gridview button column. I need to update/insert 'Y' on a specific cell in the row when I press the button
This is my gridview code
[code]....
The button column I have says delete on it but it shouldn't really delete it - Once I press the button it puts a 'Y' on a column that is filtered out by my sql statement in the sql datasource
I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button
Data Data Button
Data Data Data Button
Data Data Button
Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
sender.CommandArgument
for example returns and empty string.
I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.
I have little strange question. I would like to Validate my Page Controls on the button click which is there in the User Control. This user control is placed on the Page. If I check Page.IsValid property on button click event, it returns false. But Validation Summary message doesn't popup. So user doesn't know what's happening. It will not save the information and it won't give the validation message too.

I have a text field set up to accept a date: [Code]....
how to get the validator to make sure that the YEAR is acceptable. For instance, I can enter a year of "0000" and the validator will not catch it or display the error message. I can even enter a year of "9999" also. The only time the validator catches it is if I input something like "45/95/7589" for the date.
