I got few check box (depend on settings) that created during run time, some time the number of check box is 3, sometime is 5. And the check box ID also change based on the settings.
How can I search for ALL these check box and return its ID? I do not want to use javascript.
I have creted a checkbox for each column of grid at the top of the header in row created event. I need to check wheather checkbox is checked after button click event.
//Build custom header.
GridView oGridView = (GridView)sender;
GridViewRow oGridViewRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
TableCell oTableCell = new TableCell();
//Add Staff_ID
CheckBox chkStaffID = new CheckBox();
chkStaffID.ID = "chkStaff_ID";
chkStaffID.Text = "Hide";
chkStaffID.CheckedChanged += new System.EventHandler(chkStaffID_CheckedChanged);
chkStaffID.AutoPostBack = true;
oTableCell.Controls.Add(chkStaffID);
oTableCell.ColumnSpan = 1;
oGridViewRow.Cells.Add(oTableCell);
Once i select the checkbox on different columns then after firing the button click event i want to get which checkbox is check and unchecked.
I have a web user control with dynamic LinkButton think an event in which you assign events to them (LinkButton.Click + = new EventHandler (Method)).The problem is that these events do not run, I did test creating and if you run statically.Why is it??I need to be created dynamically at runtime.For Examples :
for (int i = 0; i <= 5; i++)
{
Button boton = new Button();

I have a form that does a loop to create checkboxes. Here is the code in the loop:
LeftPosition+=120;
cbxDrives.Top = TopPosition;
cbxDrives.Left = LeftPosition;
cbxDrives.Text = d.Name;
CheckBox cbxDrives =
new
CheckBox();this.Controls.Add(cbxDrives);
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 created one user control in which I have taken a gridview. Columns of this gridview are getting generated dynamically. (i.e. I read Column name from Xml file) But now I want my first coloumn of this gridview as a checkbox field.
I am giving my code snippet for reference.
This is function to create Grid.
[Code]....
I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.
When page loads,I get error - Specified cast is invalid!
The code is as follows...
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="dsResults"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" OnRowUpdated="GridView1_RowUpdated">
<Columns>
<asp:TemplateField HeaderText="COMPLIANT" SortExpression="RESULTS">
<EditItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("RESULTS") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("RESULTS") %>'
Enabled="False" />
</ItemTemplate>
</asp:TemplateField>
Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.
Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.
I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.
I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.
Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.
how i can edit and update Checkbox.
where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.
I am trying to allow for multiple selection check boxes that are created dynamically.
The Following code is written for each row in the dataTable (I print it as HTML code)
<input type='checkbox' name='multiCheck' id='chk{1}' value='{1}' runat='server'/>
however, on the server side (after postback) I can't read them from the Request Object. How do I "mark" them so I can read them at the postback?
protected void DeleteSelection_Click(object sender, ImageClickEventArgs e)
{
int multiIdsToDelete = Request.Form["multiCheck"]; <-- In the Future will be added to an array so I can do the delete for each row selected.
}
Im basically listing a set of facilities in a datagrid. Like so:b Projectorcb Laptopcb TelevisonIn roomview, a check appears where a facility is availble in a room. This part works fine.The user can then edit the facilities, by clicking on the check beside each facility. When the update button is pushed I need to record the value of the checkbox, however I cant get the value of the checkbox.eres my codebehind:

I have a editable gridview. When I click on edit button corresponding to a row in the gridview I provide two textboxes to enter two new values.2 textboxes as I have 2 columns. Now this textbox are generated at runtime.I want to access this textbox in javascript and perform validation on them.This is the html syntax.
[Code]....
I 'have' to use IE 6.0.
I have already tried document.getElementbyID for the table and getElementsByTagName adn they are not working.
var curValue = document.getElementById("<%=TableGridView.ClientID%>").rows;
curValue is 1 in IE and 4 in firefox.
In design time I created a Gridview and a delete button in a page test.aspx:
[Code]....
The program stopped at statement "if ((row.Cells[COL_INDEX_SELECTED].Controls[0] as CheckBox).Checked)",
because it cannot find the checkbox created before.
I tried to shift all the code in Page_Load to Page_Init, but the ticked checkboxes are still lost.
I could find the ticked checkboxes names in its request object parameters(this.Request.Params.AllKey) if I setup a breakpoint on the error statement.
Does anyone konw what's happening and how to retrieve the selected rows?
I have a question connected with controls and event handling. Lets say I want to create a LinkButton.
protected void loadLinkButton()
{
ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("MainContent");
LinkButton lnk = new LinkButton();
lnk.ID = "lnikBtn";
lnk.Text = "LinkButton";
lnk.Click += new System.EventHandler(lnk_Click);
content.Controls.Add(lnk);
}
Here is the event handler:
protected void lnk_Click(object sender, EventArgs e)
{
Label1.Text = "ok!";
}
If I run the loadLinkButton function inside Page_Load everything is ok. But when I try to run the loadLinkButton by clicking simple button, link button is created but event is not handled.
protected void Button1_Click(object sender, EventArgs e)
{
loadLinkButton();
}
I there any way to solve it? Or loadLinkButton must always regenerated on Page_Load, Page_init etc.
How would I transfer the values of an array created at runtime from one page to another? I tried using Response.Redirect because single values are getting transferred, but this isn't working properly with the array.
View 1 RepliesI have a drop down list (created during form design) with auto postback enabled. And I use AJAX to prevent 'visible postback'.
When a user choose an item from the drop down list, the system will then perform a postback and created a set of form control's such as label, drop down list and text box for entry.
Then, I will have a button (created during form design), and when I click on the button, i want to find for the form control that are created after the post back, but I cant find them!
I wonder if those form controls are render to the web form?? But I have no problem finding the drop down list that is created during design time.
I have a checkbox on my page that must be ticked and to validate it I am using a custom method as below. The problem is that I now put the checkbox and method within a Create User Wizard custom tempalte and when I submit the form it does not activate the validation check. If I put a normal button on the page outside the tempalte it works. Not sure If I a missing something. Perhaps I can activate it in Created User Event handler in code behind. All Button in my create user Event.
<asp:Button
ID="StepNextButton"
runat="server"
CommandName="MoveNext"
OnClientClick="ShowMP();"
align="middle"
CausesValidation="True"
Text="Submit
my Profile"
/>
aspx
<asp:CheckBox ID="Terms" runat="server" />
<asp:CustomValidator ID="valTandCs" ClientValidationFunction="ValidateTandCs" runat="server" ErrorMessage="Please accept Terms and Conditions before submitting."></asp:CustomValidator>
Javascript
<script language="javascript" type="text/javascript">
function ValidateTandCs(source, args)
{
args.IsValid = document.getElementById('<%= Terms.ClientID %>').checked;
}
</script>
I would like to find a way of running custom validation on a checkbox list. The reason why is because they were a radiobutton list. Then our client decided they wanted to be able to uncheck them (without a clear button) so in the end I had to change them to checkbox lists and make them mutually exclusive. On some of them, one must be selected and I downloaded this: [URL] to set them as required - worked nicely. Perhaps there's a way of building on this further to create some sort of custom checkbox validation. why I need this custom validation is because when the built form checkbox list = flat or maisonette then floor level is then required.

View 8 Repliesi would like to uncheck a checkbox in my gridview when the user clicks on that row... how do i do that in vb.
also, when trying out my website, when i do uncheck the checkboxs and click on the link to go back to the home page, the gridview on that page which links to the same table does not update the checkboxes with the new values.
I am new to ASP.NET and i have created a page where i am calling Fullname of person in Checkboxlist. When a user selects some names and clicks sendmail button , it should go into sql find out the email addresses of selected names and convert them to a mailto:aaa@ymail.com;abc@gmail.com; ask the user whichever mailaccount the user wants to use to send the mail to them.
