But what's baking my noodle is trying to figure out how to programmatically set a checkbox to checked.
The scenario is I have some rows in a GridView that are associated to another value in a dropdown. So, when I select the value in the dropdown, I'd like the checkboxes in the GridViewRows that are associated with that value to be already checked.
Problem: The check value is not persisted in the database. There's no field for it. The checkbox on the GridViewRows is an ASP TemplateField.
So I iterate through the rows and would like to check whichever checkboxes I need to based on whatever condition.
I am using YAF as my online forum. I've synched user account databases between YAF and my own application, but call 'Membership.Providers["YafMembershipProvider"].CreateUser' at the same time as I create my own members. However, there's a problem... My users are identified by email address for logon. So now the forum shows everyone's email addresses.
YAF has an option called 'display name'. Is it possible to programmatically create this as well?
I want to use a single Crystal report (.rpt) file for two actual reports, changing only the title and the data. I've got the data working, but I can't seem to get the title part right. I tried to follow this
tutorial, but when I do my report just disappears (whether I set the parameter or not). I created a "Report Title" special field and dragged it to my page header. Then I brought up the formula editor on the report title display string and clicked on my title parameter. So the formula ends up being
{?Title}
I'm sure I'm probably just making a rookie mistake here.
The error that I'm getting in Visual Studio is "Overload resolution failed because no accessible 'GetUser' accepts this number of arguments". I don't understand why it's not working.
I would like to generate an excel sheet aout of a table in asp. The exporting works fine using an in-house developed framework to export the table. The problem that I'm having is that dates are just written in columns as strings and not initialized with the proper cell format. Is there any way to format the date without any 3rd party software by just setting the value of a cell with a string??
I have created a web application will will eventually be the holding place for several reports. Rather than creating a new webform for each report, I want to use the same report viewer for all of the reports. I have created an AccountSummary dataset (AccountSummaryDS.xsd) that has two tables, one for the header information and one for the details. I have two webforms in the app, a Default.aspx that captures the necessary employee information for the query and the ReportForm.aspx that has the reportviewer control.
I came up with the code below for a Windows form application but am having issues translating it to be used in a webform.
I've tried to get a list of the IDs of the controls, but when I try to access he ID field of control at index 0 I get a null reference exeption, even though the collection has a .Count == 5. Any clue why or if it can be done and how? I've tried this both in Page_Load and off a button_click event.
Assuming you need the ID to set the proper tab index via the control collection object, the following code should produce the list of the names of the 5 controls. The output is '01234' to the multiline textbox... (the values of x)
then I would like to set the class for the li according to the controller value. How do I do that?
Something like: if controller == "home", then set the class for the li with the home id to active.
I just started learning MVC and am very new to the syntax. when you respond to this posting provide syntax, as I am coming from code behind background.
Is there a way of setting the default unchecked value of a checkbox? Am not using a databound control. This is passing data from a form and would like it to pass false as opposed to null when unchecked.
I am trying to programmatically set some lables inside a DetailsView that is populated by an ObjectDataSource. The detailsview is handled in an unusual way with one TemplateField that has one ItemTemplate that has one table that has two rows of significance and a boatload of bound items. I'll be working on the EditTemplate next. But now I need to set the top row lable values programmatically baised on the type of data that comes-up. I have scoured the Internet looking for ideas and found two possible approaches - neither worked. I get the error about something not being set to an instance of the object - or something like that.
Here is the ObjectDataSource:
[Code]....
Here is the DetailsView:

My first approach was to set the OnSelected property to the following code in the code behind, which executes:
[Code]....
My second approach was to delete that OnSelected property and try the following code in the code behind:
how i can add checkBox in gridview instead of (alpha or beta ) at tbl.row.add for is_active ?when is_active is true then checkbox.checked = true and else if is_active is false then checkbox.checked = false ??
I have a form with a checkbox list, the values of which are value = "1" value = "2' ...etc (amount of boxes not fixed). These values correspond to an id field in a database and are stored when a new user is entered. When reloading this info I want to populate the checkboxes according to how the user originally checked them. What is the correct way to do this?
while (reader.Read()) ( i = Convert.ToInt16(reader["Id"]); CheckboxList1.Items.FindByValue[i].Selected = true; }
The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.
On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.
I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.
This creates multiple check boxes on the form, and this works fine.
However, in the code behind for my button that the user clicks to execute the form, I cannot figure how how to read the values for the checkboxes. I've tried:
foreach (CheckBox cbxDrive in cbxDrives) { }
but cbxDrives is not recognized.
I need to read through all of the checkboxes to see their values, so that the appropriate actions can be performed in the code behind.
I have a formview in edit mode, with submit button and checkbox. I want to click the button and have it test to see if the checkbox is checked. The ID of the checkbox is "TestCheckBox". I figured it would be something like, If TestCheckBox.Checked then, but if I type in TestCheckBox it says it's not declared, even though it is a control in the formview.
I have a GridView with one checkbox and some fields. Now what I want is to set this checkbox dynamically on the execution of a particular function.
ie..i have a mailsend function in my code.. when this function executes the checkbox in my gridview should be set dynamically.. How do I go about acheiving this?
<asp:TemplateField HeaderText="Approval" Visible="false"> <InsertItemTemplate> <asp:CheckBox ID="Approved" runat="server"/>This must be checked to allow the insert. </InsertItemTemplate>
i'm attempting to set regular html checkbox's checked value based on if a master asp checkbox is checked or unchecked. The normal html checkbox is located in an asp repeater control that is populated in the page load event. MAIN .ASPX PAGE <asp:CheckBox ID="ChkMaster" runat="server" OnCheckedChanged="ChkMaster_CheckedChanged" AutoPostBack="true" /> [code]...
The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
