I have one table control "table1"
And added controls to it in click event of one button as :
[Code]....
but i cant retrieve this controls in click event of another button. i think it is because of postback.
I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here
my code...

I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
Here's the design I want:
ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.
I'm looking to add controls dynamically to a table across multiple functions. I'm trying to convert this from a C# app to a web app using asp.net, though this is my first time using asp.net with no web development background. I read the creating tables dynamically in the FAQ but I'm still not sure how to do this.
When pressing the submit button on my form, it will create a table in a place holder. Eventually I would like it to generate urls based on the users input and do this in a function other then the one I created my table in.
In my C# app I was able to add text to a listbox using: lstOutput.Items.Add("Text"); across multiple functions but I'm having trouble doing this with a table.
I understand that my table is a local variable in the submitButton_Click function, but how do I make it global to add rows, cells and controls to it in other functions?
My current code which doesnt work:

I have a web page where users need to enter customer contact information. They could enter from 0 to an infinite number of contacts.
I created this page code on page:
<ajaxToolkit:ToolkitScriptManager runat="Server" EnablePartialRendering="true" ID="ScriptManager1" />
<asp:PlaceHolder ID="phCustomerContacts" runat="server" EnableViewState="true">/asp:PlaceHolder>
<asp:LinkButton ID="btnAddContact" runat="server" OnClick="btnAddContact_Click" CssClass="LinkButton" Text="Add Contact"/>
In my code behind I added this:
public void btnAddContact_Click(object sender, EventArgs e)
{
IList<CustomerContactProfile> customerContacts = new List<CustomerContactProfile>();
if (ViewState["CustomerContactList"] != null)
customerContacts = (List<CustomerContactProfile>)ViewState["CustomerContactList"];
CustomerContactProfile contactProfile = (CustomerContactProfile)LoadControl("~/Controls/Embedded/CustomerContactProfile.ascx");
customerContacts.Add(contactProfile);
foreach (CustomerContactProfile contact in customerContacts)
phCustomerContacts.Controls.Add(contact);
ViewState["CustomerContactList"] = customerContacts;
}
This code doesn't work because the ViewState can't handle storing all of that control data. However, I cannot think of another way to store the controls that were already added.
The viewstate of the asp:PlaceHolder control doesn't save anything and I need the controls to be saved so that if a user puts in some data to the first control that the data isn't lost when they add a second one and so on.
I have a table with 4 cells and three rows. All rows have a textbox in it. I have a button at the top. I want to add a new row in that table when that button ic clcikded with same formatting as above row. Above row format is like this.
<tr valign="top">
<td>1.
</td>
<td align="left">
<asp:TextBox ID="txtC1Fname" runat="server" Width="150px"></asp:TextBox>
</td>
<td align="left">
<asp:TextBox ID="txtC1LName" runat="server" Width="150px"></asp:TextBox>
</td>
<td align="left">
<asp:TextBox ID="txtC1DOB" runat="server" Width="150px"></asp:TextBox>
</td>
</tr>
How Can I do this ?
I am returning an IList to my model of data about users. I want my end users to be able to select which columns they want to see.
I know I can do this with a huge "if statement" however, I know there must be a better way. I have created an Enum with the column names. I feel if I could take the IListItem.EnumName I would be set. However, I'm not too sure on how to do this.

I've been searching for hours trying to figure this out. I understand that somehow I need to recreate the control in page_load. I think seeing the code will let us better understand what I'm trying to do.

I have the following code, i add code for required validator, but when you make selection from dropdown to create the table, the page generates an error. Should the logic be somewhere else to add it to the table? i mean, dont they have to be there so when you submit the form, it fires the validation?
[Code]....
Here is the error that comes up, when i make a selection from my dropdown that creates the table.
Line: 938
Error: Sys.WebForms.PageRequestManagerServerErrorException: Control 'rfvtxtCam1' referenced by the ControlToValidate property of 'rfvtxtCam1' cannot be validated.

View 1 RepliesI have a custom control and I want to dynamically insert a link to a stylesheet.
Might not be the best solution of the year but it needs to be done.
Everytime I try, Page.Header is null.
I have a custom DDL that lives in my Server control library. Currently I add this control to a table by strongly typing the name of the control, the customary way.
Control_Library.Report_NumberDDL newDDL = new Control_Library.Report_NumberDDL();
What I want to be able to do is dynamically create that control by pulling the control name from a table. So I would have the name of the control in my code, in this case "Report_NumberDDL", and I would like to then create the control without having to strongly type it.
Something like this, though I know this doesn't work:
string controlName = "Report_NumberDDL";
Control_Library."controlName" controlNum1 = new Control_Library."controlName"();
Edit:I tried to do this:
Type type = Type.GetType("Control_Library.Report_NumberDDL");
object control = Activator.CreateInstance(type);
But on the CreateInstance(type) I get a null value exception. So the Type isn't getting created correctly.
I have a usercontrol (ascx) that I want to dynamically add to a page.
Neither the control nor the page has a namespace (thanks crappy vendor).
When I use the following, it tells me it cant find the "type or namespace"
StayTunedControl = (UserControler_StayTuned)LoadControl("~/UserControler/StayTuned.ascx");
Page.Controls.Add(StayTunedControl);
StayTunedControl.StayTunedID = Convert.ToInt32(IncludesStayTunedMeta.Value);
After some tweaking to the namespaces, etc, I am now at a point where the 3rd line above generates the following error:
'System.Web.UI.UserControl' does not contain a definition for 'StayTunedID'
I was hoping that casting StayTunedControl as type (UserControler_StayTuned) would fix this.
I am fairly new to ASP.Net and web programming in general and I am having issues trying to add values from a dropdown list in my gridview to another table.
Here is my scenario. I have 2 tables in my SQL Express DB. When editing the values of table2 in a gridview, I would like to show some data from table1 in a dropdown so users can select a value from table 1 and enter that value in table 2.
I have the Gridview setup to show table2 data.
I created a field template and inserted my dropdown list and linked it to my table1 data source.
When I run my web form, I can click to edit one of the fields in the gridview, and my dropdown list correctly displays the data from table 1, but when I try to update the table2 with the dropdown value, it doesn't correctly update. The row in table2 never updates.
posting the dropdown value from table 1 into the appropriate field in table2..
Again, I am new to this and have been following the tutorials etc on this site, but can't find one pertaining to this topic.
I have a usercontrol that uses a callback to update itself. If I add the control to the aspx page everything works fine. However, when i add the control using Page.LoadControl and Control.Add on a Placeholder i get the following error: "The target 'ctl00$ContentPlaceHolder1$ctl00' for the callback could not be found or did not implement ICallbackEventHandler". I tryed assigning the ID of the control also which failed with the same error. I am using asp.net 2.0.
View 11 Replieshow to add dynamically control to a table
View 3 RepliesI have a dynamic html table. I can create new rows by clicking 'add' button at runtime.
Each row has 3 textboxes and a fileupload control. A row can be submitted after filling the textboxes and browsing the file for upload.
A 'submit' button is there to submit a row(which will also upload the selected file).
If i select a row, fill it, choose a file to upload after browsing and click submit button, it works fine.
The problem is that if I fill a row (and not submit) and 'add' a new row, my previously selected file (filepath) disappears.
What can I do to keep the file path remain after adding new rows?
i have n ASP .net page containing a HTML-control Table (LoginTable) with a background image, i want to change the background image. the Asp page has have a masterpage also. the code i am using is,
ContentPlaceHolder Cphmain = (ContentPlaceHolder)Page.Master.FindControl("CpHMain");
HtmlTable htmlTable = Cphmain.FindControl("LoginTable")
as
HtmlTable;
htmlTable.Style.Add(HtmlTextWriterStyle.BackgroundImage,
"./images/eventmanagement.jpg");
The find control method is returning null value
here is the requirement:
i have a lable a textbox, and two buttons(+ and - button) on my asp.net page.
so when i click on the plus button it should add the the whole collection of controls to the page(i.e. lable, textbox and two buttons). And when i click on minus button it should remove the collection.
This should go on.meaning whenever i click on any plus button the control collection should get added to the page.
I am wondering what will be the best approach to do it.
I'm listing some controls at my web page dynamically, either I'm adding newline with Label's.
Label newLine = new Label();newLine.Text = "<br/>"; myPanel.Controls.Add(newLine);
How can I do it in a different way?
